Brennan Benson 7afa4ee3dc test(e2e): read the tab strip's dock samples through a typed window field (#24052)
#24010's spec read them with Reflect.get, which the low-evidence lint rejects, so every PR's static analysis now fails on main.

Brennan Benson fceca5cece fix(sidebar): an agent's row stays while it runs, whatever its tab title (#23948)
* fix(sidebar): keep hook-less agent rows while the agent runs, whatever its title

Codex retitles its pane to the project name, so the sidebar's title-derived
row (which required the title to name an agent) vanished while Codex kept
running (#23767). Rows now take identity from the canonical pane resolver
over the pane's foreground-process read and launch record, then the title;
the title only decides idle/working/needs-input. The row still goes away when
the PTY exits, the process tracker proves the shell is back, or the title is a
shell or default title.

* test(dashboard): justify the partial store fixture's type assertion

* fix(sidebar): only a live process read keeps a plain-title agent row

Review of the previous commit found ghost rows: the tab launch record is a
latch nothing clears on WSL, after an SSH exit, or for a launch that never
started, and a parked pane's process read went stale because only the
mounted tracker re-derives it.

- The launch record returns to main's role: a fallback only for titles that
  show activity, ranked below a title naming another agent (pane reuse),
  matching the tab icon's order.
- A parked pane's command boundary retires its unconfirmable process read,
  like the mounted ladder's unavailable path; reveal re-reads it.

* fix(sidebar): confirm before a parked marker retires an agent; read Git Bash prompt titles as the shell

- A parked pane's end-of-command marker can be a nested shell's leak under a
  still-running full-screen agent, so confirm the foreground first (as the
  mounted ladder does) and retire the process read only on a shell or no
  answer. SSH/remote parked panes hold no incarnation to fence a host read
  with, so they still retire.
- Git Bash emits no command marks; its `$MSYSTEM:$PWD` prompt title
  (MINGW64:/c/repo) is now shell evidence, so a stale Codex read there no
  longer keeps a ghost row after Codex exits.

* fix(sidebar): trust only process-read agents for plain-title rows; per-worktree foreground selector groups by tab

A daemon reattach seeds the pane's foreground entry with its launch agent, which
can outlive the process while Orca is closed. The entry now records where its
agent came from (agentEvidence), and the sidebar/dashboard title-derived rows
only keep a plain-title row on an actual process read. Routing and the tab icon
are unchanged.

selectPaneForegroundAgentsForWorktree grouped every pane key per worktree; it now
groups by tab once per map identity and skips worktrees with no tabs.

* fix(sidebar): a parked pane's reattach keeps its own process read of the same agent

The reattach seed marked a returning parked Codex pane as launch-record
evidence, over the process read this session already took, so its row
blinked out on reveal and stayed hidden if the user left the tab before
the visible read landed. Keep the read when it names the same agent; the
seed still drops byte-routing trust.

* test(terminal): foreground confirmation publishes process-read evidence

* fix(sidebar): a cleared pane title retires the agent's process read

Codex clears its title when it exits, and the tab then shows its default
title. A pane without shell command marks never re-reads its foreground
process, so the retained read kept a "Codex · Idle" row after /quit
(permanently for a hand-typed Codex; about 15 s while the marked-pane
confirm ladder ran). Treat a blank title like the default title it shows.

* fix(sidebar): the pane's process monitor retires an exited agent's process read

A hook-less pane keeps its sidebar row from the tracker's foreground-process
read, but nothing re-derived that read in a pane without OSC 133 command
marks. After Codex exited there, a "Codex · Idle" row stayed: permanently
when the shell titles its prompt, or when a killed Codex leaves its last
title.

The pane's agent-completion process monitor already confirms an agent's
exit (no agent and no child processes, held past its settle window). It now
reports that exit to the tracker, which retires its own process read and
runs the confirmed-shell path the visible-pty read uses. A tracker read that
names an agent seeds the monitor, so hidden panes and panes the monitor had
not polled yet are watched too. A command read in flight still decides the
pane, and launch records or other agents' reads are left alone.

* fix(sidebar): a monitor-confirmed exit leaves the next agent in an unmarked pane identifiable

The process-exit retire published shellForeground:true and left the one-shot
visible sample settled; a pane without command marks has no command start to
lift either, so a Codex typed again after quitting was never read and lost its
row on retitle. Publish shellForeground:false and reopen the sample.

* test(terminal): justify the pane binding cast in the process-exit relaunch test

Jinjing 9cdbeba06d fix(tab-bar): keep the active tab visible when the tab strip scrolls (#24010)
* fix: keep active tab visible by docking to viewport edges

Makes the current tab easier to locate in many-tab scenarios. The active tab
now sticks to a viewport edge via sticky positioning when it would scroll out
of view, with a full-foreground indicator bar for better visibility and arrow
animation when a background tab opens off-screen.

* fix(tab-bar): reveal offscreen tabs instead of nudge animation

When a background tab opens beyond the visible area, automatically scroll
to reveal it (unless hovering the tab strip). This replaces the previous
arrow-nudge animation with direct visibility. revealTabStripElement now
handles keeping the active tab visible alongside the revealed tab when
both fit, or docks the active tab when needed.

* fix(tab-bar): reveal tabs by identity, not count increase alone

Detect opened tabs by comparing tab identities independently of count
changes. Newly opened tabs are now revealed even when the total tab count
stays the same—e.g., when a tab closes as another opens.

* fix(tab-bar): track tabs by identity for reliable reveal on open/close

Replace count-based tab detection with identity tracking so the strip
correctly reveals tabs when they're added, replaced, or when the active
tab closes and switches to a far-back history tab. Removes the tabCount
parameter and simplifies overflow navigation by using identity sets.

* fix(tab-bar): defer revealing tabs until pointer leaves

When a background tab opens while the pointer hovers the tab strip, defer
its reveal until the pointer leaves. This prevents the active tab from
sliding away mid-interaction. Also support client-hosted rows taking
active state while maintaining tab dock positioning.

Brennan Benson 75040eba5a test: open, seed and read the agent-session record store through one test harness (#23986)
* test: open, seed and read the agent-session record store through one harness

Tests that open the durable agent-session record store, seed it, or read
back what it persisted now go through agent-session-record-store-test-harness.ts
instead of calling AgentSessionRecordStore.open or touching agent-sessions.json
themselves. A later change that moves the store into the chat database then
changes the harness instead of every test. No production code changes.

Tests whose subject is the JSON file itself (its .bak recovery, salvage,
schema versions, permissions, and what older builds read back) keep reading
and writing the file directly; the storage move rewrites or deletes them.

* test: address the record-store harness by the host's state directory

The harness took the store's own folder, so each caller picked one
(join(root, 'store'), or 'agent-sessions' where a test read the store the
runtime owns). A later change that moves the store into the state
directory's journal database could not tell those apart, and would have
had to edit every caller again.

Every harness function now takes the state directory, the one the test's
journal database and recovery capsule already live in, and keeps the
store in the same subfolder the runtime uses. Callers pass that directory;
store-only tests pass their temp directory unchanged. Format tests that
share a directory with harness calls take the file path from
testAgentSessionStoreFilePath.

The folder name moves from a private constant in the runtime to
AGENT_SESSION_STORE_DIR_NAME beside the store's file name, so the harness
shares it without importing the runtime. Its value and every path built
from it are unchanged.

Jinwoo Hong c3183a4556 test(e2e): let the completed-worker fake Codex answer the --help probe (#24033)

Neil b7209b5ae9 perf(git): relist only the repo whose worktrees changed, and stop blocking main on sync git (#23998)
* perf(git): stop blocking main on the open-on-remote git cascade

`getRemoteFileUrl` ran up to 6 sequential `gitExecFileSync` calls on the Electron
main thread — `remote get-url`, then `getDefaultBaseRef`'s `symbolic-ref` plus up
to four `rev-parse --verify` probes — each with its own 15s timeout and no yield
between them.

A complete async twin already existed (`getDefaultBaseRefAsync` ->
`resolveDefaultBaseRefViaExec`, sharing DEFAULT_BASE_REF_PROBES), so the sync
cascade is deleted rather than converted. `getRemoteUrl`, `getRemoteFileUrl` and
`getRemoteCommitUrl` become async; all four downstream callers were already async
(`filesystem-git-url-handlers` inside `ipcMain.handle`, `runtime-git-diff-commands`
async methods) and the provider contract already typed both wrappers
`Promise<string | null>`, so no new async plumbing was needed.

Removes 3 of the 10 `gitExecFileSync` sites and the confusing name collision with
the unrelated async `getDefaultBaseRef` in hosted-review-creation-git-state.

The base-ref regression tests keep their coverage, repointed at the public async
`getBaseRefDefault`.

* perf(git): resolve the repo root in one sync spawn instead of two

getGitRepoRoot ran `rev-parse --is-inside-work-tree` and then `rev-parse
--show-toplevel` as separate blocking spawns. Each sync git call holds the main
thread for up to its whole 15s timeout, so the spawn count is the cost — and this
function is called twice per "Add Project" on a linked worktree, once directly and
once through getLinkedWorktreeMainRepoRoot's self-recursion.

Combined into one invocation. Safe only here: in a bare repo the combined form
exits non-zero, and both that throw and the plain `false` already land on the same
marker-scan fallback. probeGitRepo deliberately does NOT combine — it has to read
`false` cleanly to go on and detect a bare repo, which the combined form's exit 128
would misread as indeterminate.

* perf(git): rebuild only the repos whose authorized roots actually changed

One worktree create called `invalidateAuthorizedRootsCache()`, which dirties every
registered owner. The next authorization-requiring IPC then rebuilt by listing EVERY
repo — and the rebuild never consulted `dirty` when choosing what to list, so `dirty`
gated only whether a rebuild ran, not its scope. At 58 repos that is 58
`git worktree list` spawns, roughly ten seconds of git wall-clock through an
admission budget of four, to rediscover roots one repo changed.

Both halves were needed; scoping the invalidation alone changed nothing.

- `markAuthorizedRootsOwnerDirty` dirties a single owner, reusing the per-owner
  primitives `registerWorktreeRootsForRepo` already used. It leaves `baseRevision`
  and the per-repo revision map alone — that pair is the global side-effect-token
  fence, and bumping it would retire in-flight tokens for untouched repos.
- `rebuildAuthorizedRootsCache(store, onlyDirty)` re-lists only owners that are
  dirty, have no listing yet, or still hold recovered roots (those are retired by
  comparison against a fresh listing, so skipping them would strand them as
  authorized). Only `ensureAuthorizedRootsCache` passes `onlyDirty`; an explicit
  rebuild keeps re-listing everything because callers use it to force a refresh —
  `filesystem-auth.test.ts` pins that contract.

`invalidateAuthorizedRootsCacheForRepo` wraps the primitive and falls back to the
global form for an unknown owner or a missing store, rather than silently skipping an
invalidation and leaving a stale allowlist. Applied to the worktree-create path.
Changes that can alter the owner SET (store swap, host/WSL re-routing, nested-repo
import, folder->git upgrade) stay global. Removal paths are not converted yet.

The allowlist contents are unchanged and the failure direction is a false denial
rather than a false allow. The relist predicate is split into its own module so it is
testable alone and the cache file stays inside its line budget without a suppression.

* test(perf): measure what git orchestration actually costs the main thread

The existing churn probe (ORCA_MAIN_THREAD_DIAGNOSTICS=1) reported spawn-initiation
cost for git/gh/glab only — its 7 call sites all sit inside git/command-runner — so
it was blind to `spawnProcess`/`runProcess`, the repo's own mandated wrapper, and to
the blocking `execFileSync('ps')` per PTY resize. That understated total churn across
115 main call sites.

- `spawn-observer.ts`: a settable seam, since shared code cannot import src/main.
  Unregistered in the daemon/relay/CLI, where it costs one boolean check.
- `spawnProcess` brackets `nodeSpawn` and reports; exec-file-capture's own report is
  removed because it routes through runProcess and would double-count.
- `posix-pty-foreground-group` now reports its full blocking duration. Note this
  lands on the daemon, not main, whenever the daemon hosts the PTY.
- `ORCA_UNMINIFIED_MAIN=1` build flag, because a minified main bundle cannot
  attribute CPU-profile self time to real function names. Defaults unchanged.
- `main-thread-git-cost.spec.ts` + `analyze-main-cpuprofile.mjs`: sweeps concurrency
  against real registered repos, captures the churn lines and a V8 CPU profile of
  main per phase.

What it found, which is why this is worth keeping: at the width-4 admission ceiling
(~90 git:status/s) main sees ZERO event-loop gaps over 50ms and a worst gap of 23ms,
and is 85% idle. Git orchestration does not stall the main thread. Of the cost it
does incur, spawn-init is 58%, parse 5%, stdout drain 4%.

* test(perf): name the inspector params type the anti-slop gate requires

The broad `object` parameter trips anti-slop(no-object-parameters); the only
Profiler call that passes params sends `{ interval }`.

Neil fb52c0602a fix(terminal): release xterm's DEC 2026 render hold instead of waiting out its 1s timeout (#23920)
* fix(terminal): release xterm's DEC 2026 render hold instead of waiting out its 1s timeout

xterm paints nothing while DEC mode 2026 (synchronized output) is open and only
force-flushes after 1000ms. Codex wraps every draw in mode 2026, so any byte gap
or chunk split that loses the closing \x1b[?2026l freezes the pane for a full
second and then repaints in one burst.

Orca never emitted \x1b[?2026l anywhere, and three paths could destroy a TUI's:
the per-PTY pending cap drops buffered output wholesale (mode 2031 was already
salvaged there, 2026 was not), main sliced pending data at a blind 16KB offset
that can land inside an open frame or sever the 8-byte marker, and the renderer's
backlog warnings replace a queued tail that may hold the close.

- salvage the 2026 latch across dropped output, mirroring the existing 2031
  salvage, and append the release on both delivery sites
- ground 2026 in RESET_AFTER_BYTE_GAP and the replay baseline, and in both
  backlog warnings, so every drop path is self-healing
- make main's 16KB flush split frame-aware instead of a blind byte offset
- lift the synchronized-output scanner into shared/ so main and the renderer
  use one implementation

Closing a frame early costs one premature repaint; leaving it open costs a
second of blank screen, so the asymmetry favours always closing.

Also adds the reproduction this needed: the pre-existing typing bench observes
the xterm BUFFER, which the parser fills while rendering is held, so it scored
these freezes as fast echoes.

* fix(terminal): stop the renderer's queue drain cutting inside an open DEC 2026 frame

takeQueuedChunk sliced a queued chunk at a blind byte offset to fit the 16KB
coalescing budget, which can strand a frame's closing \x1b[?2026l in the residual
until a later drain. Same defect as main's flush split, same fix: reuse the
frame-aware split helper.

Usually masked because the drain coalesces adjacent chunks and reassembles what
main split, but not when the budget boundary falls inside a frame.

* fix(relay): keep the SSH path's bounded slice outside an open DEC 2026 frame

pty-handler split pending output at a byte offset with a surrogate-pair guard but
no synchronized-output awareness, so a frame straddling the 16KB wire slice had
its closing \x1b[?2026l stranded in the remainder — the same defect just fixed on
the local path, on the path AGENTS.md requires us to consider.

Placed before the surrogate guard so that guard keeps the final say, and floored
at 2 so frame alignment can never walk a healthy slice into the guard's
decrement and then into the chunkChars <= 0 pause-and-retry path.

Also drops a dead `splitAt === 0` branch in takeQueuedChunk: both callers pass a
positive limit and the helper never returns 0 for one.

The two new split tests were each confirmed to fail without their fix.

* test(terminal): sweep the DEC 2026 split helper over escape-sequence shapes and every limit

Covers OSC 52, DCS, repeated open/close markers and limits 1..len+3, asserting the
result never exceeds the limit, never reaches 0, and stays byte-exact. Also pins
that a buffer beginning inside an open frame degrades to the blind offset rather
than doing something worse, and documents that callers do not thread latch state.

* fix(terminal): ground DEC 2026 on the daemon slice, the recovery replays, and the process boundary

Four more sites could strand the latch, found by sweeping every path that drops,
splits, or replays terminal bytes.

- daemon-stream-data-batcher: the 64KB bulk-write slice used a surrogate-only
  clamp, and its remainder is HELD until 'drain' — "seconds for multi-MB
  backlogs" per the file's own note. A frame straddling that boundary parked its
  \x1b[?2026l behind the hold, blanking the pane past xterm's 1s timeout once per
  frame for as long as the backlog lasted. This is the default daemon-backed pane
  path, so it is the one users actually hit. The new
  clampToSafeBulkWriteSplitIndex frame-aligns first and surrogate-clamps last,
  and lives in daemon-stream-data-split alongside the policy it belongs to.
- replay-data-drain and remote-runtime-terminal-binary-snapshots wrote a bare
  \x1b[2J\x1b[3J\x1b[H, which does not clear mode 2026 — so on the SSH/remote
  reconnect path, the very event most likely to sever a frame, the whole replay
  could paint nothing.
- ipc-pty-attach: trimIncompleteTerminalControlTail can cut a half-written
  \x1b[?2026l while its opening marker survives in the replayed prefix.
- PROCESS_BOUNDARY_GROUND: the "process that armed these modes is gone" ground
  omitted 2026, the last unexplained gap in that file. A disable, so it still
  satisfies the recovery barrier's ownership scan (only ?25h may be an enable).

Recovery-path expectations updated where they pin the emitted bytes. Deliberately
NOT touched: apply-reattach-payload and ssh-snapshot-prepaint already ground via
buildSnapshotReplayPrologue.

Still unfixed, deferred with reason: terminal-output-frame-chunks.ts splits the
remote wire on accumulated UTF-8 byte width and needs a different shape than the
char-index helper; desktop clients reassemble in main's pending buffer, so the
exposure is mobile/web only.

* fix(terminal): emit the DEC 2026 release before the mode-2031 tail, and stop claiming the drop path writes it

Two corrections from adversarial review of the earlier commits.

1. Ordering bug I introduced. getDroppedMode2031RendererData ends with
   `state.tail`, which extractPrivateModeScanTail deliberately retains as an
   INCOMPLETE private-mode sequence so the next chunk can resolve it. Appending the
   2026 release after it put an ESC behind a dangling CSI, aborting it and silently
   losing whatever mode spanned the drop boundary. The release now goes first.

2. The drop-path release does not reach xterm in the dominant case, and the comment
   now says so instead of implying otherwise. live-data-callback's droppedOutput
   branch discards `data` and salvages only queries
   (salvageRendererQueriesFromDiscardedRestoreData handles CPR/DA1/OSC colour;
   \x1b[?2026l is not a query), so for hidden panes and visible panes outside
   foreground-restore backpressure the synthesized release was dropped. The grounded
   snapshot replay releases the latch instead.

   I tried writing it through writePtyOutputToXterm there and reverted: it consumes
   the pending hidden-output snapshot and broke
   pty-connection-hidden-snapshot-resize-signals ("re-restores a skipped alt frame"),
   so the release rides the restore rather than perturbing that state machine.
   Residual gap, documented: a cap-dropped pane whose restore never arrives.

The salvage is still load-bearing on the fall-through path, so it stays.

* fix(terminal): release DEC 2026 on the reattach clears, floor the split, and correct the freeze framing

Remaining findings from adversarial review.

- apply-reattach-payload's three bare-clear branches (:63 daemon snapshot, :229
  relay replay, :269 cold restore) had no release anywhere in their sequence: I
  checked all seven POST_REPLAY_* profiles reachable via chooseReattachReplayReset
  and none contains \x1b[?2026l. Only the buildMainModelSnapshotReplayWrites branch
  was grounded, so covering the streamed replay path and not the main reattach path
  was inconsistent. Verified no production code matches these clear strings — the
  three test updates are mock equality, and each was confirmed to fail without the
  source change.
- clampToSafeBulkWriteSplitIndex could return 0 (('\u{1F600}aaaa', 1) — alignment
  returns 1, the surrogate clamp decrements to 0), which would leave a zero-length
  slice that never shifts the batcher's queue entry and spin its drain loop.
  Unreachable from today's only caller, but it is exported with an unstated
  precondition. Floored at 1.
- Frame alignment could halve per-PTY flush throughput: main re-queues the
  remainder with eligibleRound = round + 1, so the shortfall cannot be refilled in
  the same round, and aligned size is floor(W/F)*F — 50% worst case in the 8-16KB
  band, which is exactly the full-screen redraw burst that reaches the pending cap.
  Alignment is now rejected below half the window, preferring throughput and
  letting the reset profiles release the latch.

Framing corrected throughout: bufferRows records a row range and clears nothing, so
the pane freezes on its last painted frame — it does not go blank. The real trade is
"stale but coherent for <=1s" versus "immediate partial frame", and
RESET_AFTER_BYTE_GAP (written alone, with no repaint behind it in the same write) is
the one site that can newly flash a partial frame. Said so at the constant instead
of implying the release is free.

* fix(terminal): rename the shape-flagged symbols the anti-slop audit rejects

CI's anti-slop gate rejects "shape" in symbol names as structural rather than
domain language: `shapes` -> `outputSamples`, and
`writeCodexShapedEchoProbeScript`/`codexShapedEchoProbeScript` ->
`writeCodexEchoProbeScript`/`codexEchoProbeScript`.

Neil bb667a33bd test: retire the last private-predicate duplicates in the leaked-internals sweep (#23949)
Sixth and final wave over the modules that export symbols only tests import.
Deletes private-predicate cases whose behavior is already asserted through the
module's real entry point, then makes the symbol private again.

Also removes three distinct junk shapes the earlier detectors missed:
- a self-comparison whose expected empty row was produced by the helper under
  test (`worktree-palette-search`), now a literal;
- expected values computed by a sibling helper rather than asserted
  (`terminal-theme`), now read through the production `getBuiltinTheme`;
- a negative control that cannot fail — `expect('json' in jsonlMonarchLanguage)
  .toBe(false)`, where `IMonarchLanguage` has no such key, so it guarded nothing
  while appearing to guard "does not attach the JSON language service".

Dead production code removed where tests were its only callers:
`refreshWindowsTerminalCapabilities` (a one-line alias for
`loadWindowsTerminalCapabilities({force: true})`), `readSpoolRecords`,
`buildAgentPromptSubmitBytes`, and `getCommitMessageModelCapability`.

About 70% of everything this detector flagged across the whole vein was a false
positive, so most modules were left untouched. Bounds consumed as test input,
`*ForTests` seams, non-hook cores of `useSyncExternalStore` hooks, and
value-position registrations all look identical to a leaked internal from the
outside and are not.

Brennan Benson 59b746ff3c feat(native-chat): one structured-chat journal database per host, owned by one process (#23613)
* feat(native-chat): one structured-chat journal database per host, owned by one process

Every structured chat on a state directory now lives in one SQLite file,
agent-session-journal.db, opened once by the process holding
agent-session-journal.owner: an empty SQLite file whose held BEGIN EXCLUSIVE is a
kernel byte-range lock, refused while another process holds it and released when
the holder dies.

- Stores own no connection: the per-chat handle, its close contract and the
  close-retry registry are gone; closing a conversation drains its writes, and the
  one connection closes last at teardown.
- The owner lock is taken at runtime start, before orca-runtime.json is written;
  a process that does not own the chats is not published and refuses every
  structured request with journalUnavailable and words that say what to do. It
  retries the lock with backoff and runs the full install once it holds it.
- A journal that will not open fails the host install: every chat says "Unable
  to load this chat." (journalCorrupt), and nothing is renamed, deleted or
  rebuilt. A newer build's database is refused and left byte-identical.
- An append is one INSERT. The listing status is a column, written after the
  rows it describes and keyed by (epoch, sequence).
- A per-chat journal from an earlier build is copied in verbatim (epoch UUID and
  every sequence) on that chat's first open, and its directory is retired only
  after the copy commits.
- auto_vacuum = INCREMENTAL, with freed pages handed back in bounded steps after
  every delete.

* perf(native-chat): key journal rows by block so one chat's rows sit together

Each chat's live epoch owns a block of row ids, block * 2^32 + seq, so a chat's
rows share leaf pages with nobody else's, a replay is one range scan, and
replacing or rewinding a chat deletes one contiguous range. Measured on the
largest real chat (61 MB) beside 19 interleaved peers: 39 ms and 7.5 MB of WAL,
against 214 ms and 102 MB for a (session_id, epoch, seq) key.

- Ids are computed in Number arithmetic, never bitwise. A sequence is refused
  outside [1, 2^32) and a block at 2^21, which keeps every id below 2^53.
- A replace, roll or import allocates a fresh block, moves the chat's pointer,
  and deletes the old block in the same transaction, so no orphan block exists.
- The listing status write moves into its own writer beside the column.

* feat(native-chat): copy a chat's per-chat journal again when an older Orca wrote it after a downgrade

A per-chat journal.db that reappears after its chat was copied in is the newer
history: an older build, run after a downgrade, attached the chat and wrote it.

- journal_imports records the (epoch, tip) each chat was copied from, in the
  copy's own transaction. A file already copied is never copied again, across
  any number of restarts after a failed rename; a file that differs always is.
- Newest writer wins, per chat, with a row saying the chat was continued in an
  older version of Orca. When both builds wrote past the recorded tip under one
  epoch, the copy takes a fresh epoch, so readers reset instead of skipping rows.
- Each copied directory retires to its own .imported-<epoch8>-<ms> name, so a
  second downgrade and re-upgrade never collides with the first.

* test(native-chat): fixture deps match the host journal database shape

Attach-flow and reconcile-attach fixtures stop passing a journal database those inputs do not take, and host and restore fixtures pass the one they now require instead of the removed journal root.

* test(native-chat): state why the runtime-state fixtures' existing casts are safe

* fix(native-chat): start up normally when this process cannot open the chat journal

A process refused the chat journal, because another Orca owns it or because its own journal will not open, failed startup restoration: the window booted in degraded no-save mode and a paired phone could not list any tabs. Startup restoration now treats the refusal structured requests are getting as having no structured host; terminals, tabs and saving go on, structured requests are still refused by the gate, and the install is retried on the next one. Any other install error fails startup as before.

* test(native-chat): name the owner-lock sweep test after the two sweeps it runs

* fix(native-chat): session history and terminal resume work while chats are refused

Session history (listing and preparing a resume) and a terminal typing a resume command only check whether a structured chat owns a provider session. In a process refused the chat journal they failed outright. They now take the refusal chats are getting as having no structured host, the same treatment startup restoration gets, through one shared helper; any other install failure still fails them. Chat requests keep the gate's refusal.

* test(native-chat): the first-work rename's fake journal saves the listing status

* fix(native-chat): open a chat whose per-chat journal file never got its schema

A crash between creating a chat's journal.db and creating its tables left an empty or schema-less file. Each chat used to open that file as an empty chat; the importer instead refused the open as "try again" forever. A file with no journal_sessions table is now read as never written, the same as one with no rows. A file that is not a database, or whose read fails, is still refused.

* fix(native-chat): let the event loop run between chats during startup restore

Opening a chat's journal is synchronous SQLite now that no per-chat directory
is created first, so the restore of every visible chat ran as one main-thread
task. Each chat now waits for a macrotask before it opens.

* fix(native-chat): import a per-chat journal in bounded batches

The one-time copy of an earlier build's per-chat journal ran as one
transaction, which blocked the main thread for 650 ms on the largest chat.
Rows now copy 512 at a time, each batch its own transaction, yielding to the
event loop between batches. The rows go into a block journal_import_blocks
reserves, which no reader follows and no other chat is allocated; the last
batch publishes the chat's pointer, repair marker and import marker together
and releases the reservation. A copy that stops midway leaves only that
block, which the next open clears and copies again. Two opens of one chat
import one after the other.

* fix(native-chat): refuse chats when the owner lock file cannot be opened

A lock file that is not a database, or cannot be opened, made the claim throw
before any refusal was recorded, so startup restoration failed on every
launch. The claim now sits in the same try as the database open and records
the same typed refusal.

* fix(native-chat): finish reclaiming pages a delete frees during a running pass

A reclaim pass ended as soon as the freelist stopped shrinking between steps,
so a second delete that freed more than one step's worth mid-pass ended it
early and left those pages on the freelist. A pass now ends only when a step
itself frees nothing, or the freelist is empty.

* test(native-chat): desktop session history is served while chats are refused

* fix(native-chat): a send to a chat holding a newer Orca's rows says to update

A chat opened read-only because a newer Orca wrote rows to it answered a send
with the generic write failure. It now refuses the way a database a newer Orca
wrote does, with the same reason and words.

* fix(native-chat): keep chat tabs while this process cannot list its chats

A process whose chats another Orca owns, or whose chat journal will not
open, has no structured host. Its session-tabs inventory still answered,
with no chat rows, and the renderer read that as "every chat was closed":
it removed the restored chat tabs and the next session save persisted
their placement away.

The inventory now says `agentSessionsUnverifiable` when the last tab
restore ran with chats on disk but no host to list them. The flag is set
and cleared at the per-client projection point beside the client-hosted
page hold, and the restore is memoised only once a host answered, so a
later lock takeover or journal open republishes the chats and clears it.
The renderer keeps agent-session tabs, and keeps cancellation tombstones,
against an inventory that does not affirm its chat set.

* fix(native-chat): say chats are open in another Orca, with this process's way past it

A process refused because another Orca owns the profile's chats sent the
generic `journalUnavailable` reason, so current desktop and phone surfaces
said "couldn't open this chat's history right now. Try again." — a step
that never helps while the other Orca runs.

The refusal now names its own reason, `journalOwnedElsewhere`, with the
refused process's kind (dev desktop, packaged, orcad) as a fact. Each kind
gets its own step: quit the other Orca, or give this one its own profile
(ORCA_DEV_USER_DATA_PATH) or data folder (ORCA_USER_DATA). The sentences
are added to the shared notice copy, the desktop catalogs in all six
locales, and the boot catalog.

A client that predates the reason reads it as none and keeps the code's
words; an unknown kind reads as the packaged app's step. The `message`
released clients print is unchanged. Which requests refuse does not change.

* fix(native-chat): restore chats on taking ownership, without a list to ask

A refused startup kept its hostless result, so after the owner quit this
process never installed a host, never reconciled restart leases, and kept
telling clients it could not list its chats until a desktop chat request.
Taking the lock now reruns startup restoration once and pushes the chats.

* test(native-chat): a navigation reply says chats are unverifiable while refused

* fix(native-chat): retry a refused owner lock at most every 5 seconds

The lock frees as its holder exits, but a refused process only learns that
on its next retry, and the 30 s cap left a second Orca refusing chats for up
to half a minute after the owner quit. One retry is an open and BEGIN
EXCLUSIVE on an empty file.

* fix(native-chat): install before deciding whether a takeover must republish chats

A list that landed on the refused startup after the lock was taken finished
after the takeover had already checked, so nothing republished. The takeover
now installs first, waits for any restore in flight, and restores only then;
the restore that clears "cannot tell" pushes the frames itself, so a list
that heals the inventory first reaches subscribers too.

* fix(native-chat): no takeover lands a host after the runtime stop

Quitting cancelled a refused claim's retry only at its end, so a retry firing
during the stop's awaits took the lock and installed a host the stop never
tore down, and the lock was then released under an open journal. The stop
now cancels the retry first, keeping the refusal, and repeats its teardown
while an install that began during it (a takeover already under way) is
pending, so no journal connection outlives the lock.

* fix(native-chat): show a thrown refusal in its own words, not its code

A refusal the host throws reaches the client as an RPC error whose message is
the bare code; its reason and facts ride only in the error's data, which no
client read. The chat pane's status line therefore printed
agent_session_journal_unreadable, a send took the bare "not sent" path, and
other writes said the outcome was unconfirmed.

One shared reader, agentSessionThrownRefusal, now reads the refusal from the
error data. A failed history read shows the refusal's read-history words, a
send keeps the refusal behind its Retry exactly as a returned refusal does, and
the other writes (desktop and phone) name the refusal instead of doubting the
outcome. The phone's read failure goes through the same reader.

* fix(native-chat): log a failed journal open once per distinct failure

Every chat request retries a journal open that failed, which is intended, but
each retry also logged the failure with its full stack: a junk database file
logged the same "file is not a database" error 189 times in a minute. The open
now logs a failure only when its code and message differ from the last one
logged, and forgets it once an open succeeds. The retry is unchanged.

The open moves to its own module beside the runtime, which had no room left.

* fix(native-chat): restore lists a chat from its per-chat file and copies it on first use

Startup restore opened every restored chat, and that open copied the chat's
per-chat file into the host database, so the first boot after an upgrade paid
the whole one-time copy before the chat list appeared.

A restore open now reads a chat that is still in its per-chat file straight
from that file, read-only, with the importer's own reader, and closes the file
before moving on. That read drives the listing, the status row and the
restart offer, as it did when every chat had its own file. The copy becomes
owed work on the chat's write queue: it runs before the chat's first write,
and a reader that reaches the chat awaits it. A chat the host already holds,
or that was copied before, still opens through the import and its reimport
rules, and so does a file whose read needs a repair written.

* fix(native-chat): no host stays registered after a stop an install spanned

Each teardown pass clears the registered host before it awaits an install in
flight, and that install registers its host when it finishes. The pass then
tore the host down but left it registered, so a request after the stop was
served by a host whose journal was closed. The stop now clears the slot once
its passes are done.

* fix(native-chat): checkpoint the journal with a full flush on macOS

synchronous = FULL fsyncs each commit, but macOS fsync leaves the drive cache
unflushed, so FULL alone does not survive a power loss there. With
checkpoint_fullfsync, each checkpoint uses F_FULLFSYNC; elsewhere it is a no-op.
The comment that said FULL alone was enough is corrected.

* fix(native-chat): delete a per-chat journal once its copy verifies

An imported chat's per-chat file was kept under an `.imported-*` name, which
doubled the disk its history takes. The copy now reads back from the host
database before it is published: its items, submissions, epoch and tip must
match the file's. Only then does one transaction publish the chat with its
import marker, and the file and its WAL files are deleted, the directory too
when nothing else is in it (a pre-SQLite transcript there is kept).

A copy that does not match is never published: the file stays, the chat is
refused as unreadable ("Unable to load this chat."), and the mismatch is logged
once. A file left behind by a failed delete or a crash matches the marker, so
the next open deletes it rather than copying it again; a file an older build
wrote after a downgrade still differs, and is still copied again.

* fix(native-chat): verify an imported chat a batch at a time

The check that a copied chat reads back as its per-chat file folded both whole,
each in one synchronous task: over half a second on the largest chat. Both
reads now go a batch at a time between turns of the event loop, like the copy
itself, and count rows as well, so a copy that lost a row with no item in it
is caught too.

* fix(native-chat): restore reads a chat's per-chat file a batch at a time

Restore folded a chat still in its per-chat file in one task, so the largest
chat's file held the main thread for about half a second at startup. The fold
now takes the file a batch of rows per turn of the event loop, into the same
fold a replay uses, and nothing reads it before it is done. The file is still
closed before restore moves on.

* fix(native-chat): end a per-chat copy on a turn of its own

A chat's first open ran the copy's last steps (the verified publish and the
per-chat file delete) and the replay of what was copied in one task. The copy
now yields before it returns, so the replay, which every open runs, is a task
of its own.

* fix(native-chat): commit a per-chat copy's batches without an fsync each

Each 512-row batch of a chat's first-use copy committed under synchronous =
FULL, so a large chat paid one fsync per batch, about a quarter of its first
open. The batches now commit under NORMAL, set and restored in the batch's own
task so no other chat's commit runs under it. The publish that makes the copy
visible still commits under FULL, and under WAL that sync makes every earlier
batch durable with it. A crash before it leaves only the unpublished block,
which the next open clears and copies again.

* fix(native-chat): roll back a chat journal transaction whose COMMIT fails

The shared connection's transaction rolled back only when its body threw. A
COMMIT that failed left the transaction open, so every later write, for any
chat, failed with "cannot start a transaction within a transaction", and reads
saw rows that never committed. Under the unsynced copy the failure also tried
to restore the sync level inside the open transaction, which SQLite refuses,
so the caller got that error instead of the COMMIT's.

One transaction helper now covers the body and the COMMIT, rolls back whatever
transaction survives, and rethrows the original error. Schema creation uses it
too. If that ROLLBACK fails as well, the connection is marked stranded: each
later use retries the ROLLBACK, and until one goes through every chat gets the
same "history unavailable, try again" refusal a journal that will not open
gives. The rollback that frees it also restores the FULL sync level.

* fix(native-chat): keep the chat journal connection until its close succeeds

Closing the journal dropped its connection handle before closing it. A close
that failed left the database reporting itself closed with the connection still
open, so the stop that retried the teardown found nothing to close and released
the owner lock over a live connection.

The handle is now dropped only once the close succeeds. A failed close keeps
the runtime pending and the lock held, and the next stop closes that same
connection before it releases the lock.

* fix(native-chat): publish the runtime only once it holds the chat journal lock

When this process could not open the owner lock file at all (a permission
error, or a file that is not a database), the runtime counted that as owning
the chats and wrote orca-runtime.json. That overwrote the real owner's entry,
so the CLI was sent to a process that cannot serve its chats.

A claim that throws is now refused like one another process holds: the runtime
starts but does not publish, the claim's existing retry keeps asking for the
lock, and discovery publishes once the retry takes it. Chats still get the
refusal for the failure itself, and startup restoration reruns on the takeover
the same way it does after another owner quits. A sole process whose lock file
never opens is not found by the CLI until it does.

* fix(native-chat): keep a chat's history when an older build started it over

The first copy deletes a chat's per-chat file, so an older build run after a
downgrade finds no file and starts the chat from nothing. On the re-upgrade that
fresh file was copied in as the newer history, replacing everything the shared
database held for the chat, and then deleted.

A file whose epoch is not the one last copied and that opens with
`session_created` is now kept: neither copied nor deleted, and the chat keeps
the history it has. A file that carried the copied epoch on is still copied
again, as before.

* test(native-chat): pin which chats startup restore copies

Restore copies a chat still in its per-chat file only when restore itself has
to write to it: settling what the last run left open, here a running tool call
or a send handed over and never answered. Every other restored chat stays in
its file until its first use.

* test(native-chat): pin the copy wait on a read that opens a chat restore opened

A read queued behind restore's open of the same chat reaches the conversation
through its own open rather than the listing. It must still wait for the
owed copy, or it reads the chat before its history is in the one database.

* fix(native-chat): record a set-aside per-chat file so no later open reads it

Setting aside a file an older build started over is decided once and kept in
the new `journal_set_aside` table (schema 2, additive), with the file's epoch
and tip as they were. Every later open of the chat skips the file without
opening it, across restarts and after the older build writes more to it:
anything written there grows from that build's own start, never from this
build's history.

The best-effort delete moves beside the per-chat file reader.

* fix(native-chat): set aside any per-chat file at an epoch this build never copied

A chat's per-chat file is deleted once its copy verifies, so a file that
reappears at another epoch was never this build's history, whatever its first
row says: an older build started the chat over, possibly rewinding it after
(`handle_forked`), or rolled the epoch of a file whose delete had failed.
Copying any of them would replace everything the chat holds, so each is set
aside. Only a file still at the copied epoch is copied again (it grew) or
deleted (it did not). The first-row check is gone.

* fix(native-chat): copy a reappearing per-chat file again only while this build has not written past the copy

A per-chat file that an older build carried on under the copied epoch was
copied again even when this build had also written to the chat since the
copy, or had rolled its epoch. The second copy replaced the chat's block,
so what was sent in this build after the copy was gone for good.

Now the file is copied again only when the chat still stands exactly as it
was copied: the same epoch and tip the import marker recorded. Otherwise it
is set aside like any other file that is not this build's history, left on
disk untouched and recorded so no later open reads it. A second copy
therefore never replaces rows this build wrote, keeps the file's own epoch,
and the fresh-epoch rewrite goes away. The row it adds now says the history
includes what the older version recorded, not that anything was replaced.

* test(native-chat): pin that a chat founded here keeps its history, and the v1 schema upgrade

A chat this build founded has a pointer and no import marker, so a per-chat
file an older build later starts for it is set aside. Nothing pinned that
half of the rule: letting such a chat be copied again replaced its history
and every test still passed. A second test pins that a database written at
schema version 1 upgrades in place, gaining the set-aside table and keeping
its import markers.

* test(native-chat): drop a lost copied row by patching the source, not wrapping it

* chore(mobile): restore the mobile lockfile to main's

* fix(native-chat): pass a classified journal refusal through a send or Stop unchanged

* fix(native-chat): refuse a read whose owed copy fails as a failed open does

* test(native-chat): measure only the replace's WAL in the block-key case

Opening the chats starts a free-page pass that waits one event-loop turn,
and the seed never yields one, so that pass was still pending when the
replace committed. It woke during the async stat and reclaimed the pages
the replace freed, adding ~500 KB of WAL whenever the stat lost the race
(Linux CI). Drain that pass before measuring and stub the replace's own.

* test(native-chat): the RPC fixture's status journal can save its listing status

The status feed now hands every projection to the journal, which decides whether it is worth saving.

* test(native-chat): state why the RPC fixture's status journal cast is safe

* fix(native-chat): refuse a per-chat copy whose rows differ from the file, not only its counts

* fix(bench): build the replay benchmark's baseline arm from the base tree and release its handles on failure

* fix(native-chat): retry a failed listing status save on the next read of a cached status

* refactor(native-chat): drop the chat journal owner lock; the process instance lock already guards the profile

The journal carried its own exclusive lock, with a retry loop, an in-process
takeover, lock-gated runtime discovery and a "chats are open in another Orca"
refusal. Every shipped process kind (packaged desktop, serve mode, orcad)
already refuses a second instance on one profile before the journal opens, so
the lock only ever mattered for dev desktops, which the next commit covers at
the process level instead.

The host now opens its one journal connection at install with no lock. What a
sole process whose journal will not open needs stays: the install refusal
recorded for the gate, the no-host startup path, and the unverifiable chat
inventory, now in structured-agent-session-host-refusal.ts. The unreleased
journalOwnedElsewhere reason, its processKind fact and their copy are removed.

* fix(startup): dev desktops take the single-instance lock, and a second one says why it quit

Dev skipped Electron's single-instance lock so parallel `pnpm dev` runs from
several worktrees would not quit silently, but two dev processes on the
default orca-dev profile then write the same stores at once. Dev now takes
the lock like packaged builds: a second launch on the same profile focuses
the first window and exits with code 3, printing one stderr line that names
the taken profile and how to run another copy (ORCA_DEV_USER_DATA_PATH).

Serve mode, the macOS diagnostic bypass and the E2E harness are unchanged:
an E2E launch still skips the lock unless it sets
ORCA_E2E_ENFORCE_SINGLE_INSTANCE_LOCK=1.

* refactor(native-chat): key journal rows by chat, epoch and sequence

Rows in the host's journal database are now addressed by the chat's own
identity, with `(session_id, epoch, seq)` as the primary key, the same
shape each per-chat file already used. The block-keyed layout goes with
everything built on it: the block column and its allocator, the 2^21
block ceiling, and the import's reserved block table.

A first-use copy writes its rows under the file's epoch, which the chat's
pointer does not name until the verified copy publishes it, so no reader
sees a half-copied chat. A try that stopped midway leaves only rows no
pointer names, and the next try deletes them before it copies again.
Replace, rollover and repair delete by (chat, epoch).

This build's history always wins: once a chat was copied or founded here,
any per-chat file that reappears is set aside, and the same-epoch copy
again after a downgrade is removed.

The bounded free-page reclaim after every delete is dropped;
`auto_vacuum = INCREMENTAL` stays at file creation, so a later periodic
reclaim can still be added. Session search keeps its own step.

The schema moves to version 3. Versions 1 and 2 were written only by
unreleased builds of this change and are refused as found, not migrated.

* fix(native-chat): open a chat journal a newer Orca wrote read-only instead of refusing it

After a downgrade, the host's journal database carries a newer user_version. It was refused
outright, so every chat's history disappeared. It now opens on a read-only connection, as the
per-chat journals did: each chat shows what this build can read, from the database or a per-chat
file never copied in, and every write is refused with "Chats were saved by a newer Orca. Update
Orca to keep using them." Nothing is written, copied, repaired or founded, and the file stays
byte-identical. A table the newer schema changed reads as the same read-only refusal, not damage.

* refactor(native-chat): leave the saved listing status to the change that reads it

Nothing in this change reads the per-chat listing status column: it was a stored copy of a fact
the status feed derives, written after every turn end and cleared on every epoch change. The
status_json / status_seq columns, their writer, the saved-status type, the status feed's save and
its retry on a cached projection all go, with their tests. The change that lists chats from a
saved status adds the column back beside its reader.

* fix(native-chat): a chat saved by a newer Orca says to update Orca, not to try again

When a newer Orca wrote the chat journal, this build opens it read-only. A send or a Stop was
refused with the reason `journalUnavailable`, so today's desktop and phone clients chose the
words for an open that can clear: "Orca couldn't open this chat's history right now. Try again."
Retrying never cleared it; only updating Orca does.

The refusal now names its own reason, `journalWrittenByNewerOrca`, whose words are "Chats were
saved by a newer Orca. Update Orca to keep using them." A read refused the same way names it
too. An older client does not know the reason, drops it, and falls back to the code's words
("Orca couldn't read this chat's saved history."), and released clients still print the message.

* fix(native-chat): a chat journal from an unreleased build reads as unusable, not as retryable

A chat journal database stamped with schema 1 or 2 was written only by unreleased development
builds of this change. Opening it threw a plain error, which every chat reported as "Orca couldn't
open this chat's history right now. Try again." Retrying never cleared it.

It now throws a named error that is classified as unusable, so every chat says "Unable to load
this chat." The one log line names the file, says an unreleased development build wrote it, and
says to move it aside. Nothing migrates or renames it.

* docs(native-chat): drop the second-Orca-owns-the-chats case from three comments

The chat-only owner lock is gone, so only a chat journal that will not open leaves a runtime
unable to list its chats.

* docs(native-chat): correct three chat-journal comments the redesign left behind

A per-chat file left without its WAL is set aside, not copied again; nothing runs an incremental
vacuum yet, so the auto_vacuum mode is kept for a later pass; and the idle sweep drops a chat's
in-memory fold, since a chat holds no journal connection.

* refactor(native-chat): stop exporting chat-journal names nothing imports

Each is used only inside its own module now; the teardown's export served a deleted test.

* test(native-chat): name the version-0 test for what it covers, and check every journal table

The test named 'migrates an older user_version forward' covers only a version-0 file that already
has its tables; versions 1 and 2 are refused. The table test now also checks journal_imports and
journal_set_aside.

* fix(startup): a second dev launch's exit line no longer claims it focused a window

The running dev instance may be a background launch or a server, which show no window. The line
now says only that this launch passed its request to that instance.

* fix(native-chat): a failed structured-chat install closes the journal connection it opened

The install opened the chat journal database and closed it only if the record store then failed
to open. A later failure, such as the model catalog wiring or the host constructor, left the
connection open, and the next install opened a second one in the same process. Every failure
after the open now closes it.

Brennan Benson 21d4ae9448 feat(agents): pre-trust the folder wherever Orca starts an agent (#23744)
* feat(claude): pre-trust worktrees Orca creates

Claude Code asks "Do you trust this folder?" on first launch in any folder it
has not seen, which blocks unattended launches in worktrees Orca itself made.
Orca now records where a worktree's content came from when it creates it, and
before each Claude launch writes Claude's own folder-trust entry for that
worktree's root (never the main checkout) when the new setting is on and the
content is the user's repository. Forks, bare commits, folder workspaces and
external checkouts keep Claude's prompt. The write takes Claude's lock, never
creates or breaks the file, runs on the SSH host itself, and is revoked when
the worktree is removed or the setting is turned off.

Launches that already pass --dangerously-skip-permissions also skip the trust
prompt for that one process only, via CLAUDE_CODE_SANDBOXED=1 on the command.

* fix(claude): parse the relay trust request with a schema and ship its search keys

* fix(claude): never write a WSL guest's trust into the Windows config

A WSL worktree's Claude reads the guest's own config. Two paths still wrote
its trust into the Windows host's ~/.claude.json instead: the Claude auth prep's
fallback (runtime 'wsl' but the host config dir, when the WSL home cannot be
resolved), which wrote a Linux-path key the removal revoke can never delete;
and the Agent Teams leader, which passes no auth or distro and wrote a UNC key.
Require the guest's own config dir, and treat any WSL worktree path as guest-only.

* revert(claude): drop the skip-permissions trust shortcut

Pre-trust stays limited to worktrees Orca creates from the user's own
repository. The per-launch CLAUDE_CODE_SANDBOXED prefix skipped Claude's
trust question in every folder for launches carrying the skip-permissions
flag (Orca's default Claude args), including the user's own folders and fork
PR worktrees, and the setting could not turn it off. Remove the prefix, the
inherited-variable strip that existed only for it, and the Agent Teams
leader-to-teammate propagation; restore the tests that pinned the prefixed
launch string.

* fix(claude): revoke SSH trust in the config file the grant used

At spawn the relay resolves Claude's config from the launch env, which carries
a CLAUDE_CONFIG_DIR set in Orca's Claude default env. claudeTrust.converge had
only the relay's own process env, so removing the worktree or turning the
setting off revoked in the default file and the grant outlived the worktree.
Send the config-file keys with the request, as the local revoke already uses.

* i18n(settings): translate the Claude worktree trust setting

* fix(settings): say Claude trust applies when Orca starts Claude

The description said Claude skips its trust prompt in any worktree Orca
created. Trust is written only when Orca itself starts Claude there, so a
`claude` typed by hand in a fresh worktree still asks. Say that, and bring
the es/fr/ja/ko/zh translations in line with the new text.

* fix(worktrees): treat a base on an Orca-added fork remote as fork content

A worktree based on a named ref was always stamped as the repository's own
content, so picking the fork remote Orca adds for a pull request (or a local
branch tracking it) as the base made a fork's code eligible for Claude trust.
At create time, read the repo's `remote.<name>.orca-created` markers and each
branch's tracked remote in one `git config` call; a base on such a remote is
stamped as a fork's content, and a read failure is not vouched for. Remotes
the user added, such as `upstream`, stay first-party.

* perf(claude): revoke worktree trust once per config file, not per worktree

Turning "Trust worktrees Orca creates for Claude" off read and parsed the
whole Claude config once per Orca worktree on the main process. Group the
revocations by config file locally and by SSH connection, and make
claudeTrust.converge take a batch of requests.

* feat(settings): one agent-wide "trust the folder" setting in Settings > Agents

Replace the Claude-only worktree trust toggle with a single setting,
agentWorkspaceTrustEnabled (on by default; unreleased, so no migration).
The row says what it does for every agent: agents Orca starts skip their
"trust this folder?" prompt in that worktree or folder, turning it off
stops new trust while existing trust stays, and while it is off unattended
launches (orchestration workers, automations, the phone) stop at the
agent's trust question until someone answers.

Translations for es/fr/ja/ko/zh. Also restores the `awaitingUnnamed` chat
catalog keys an earlier merge of main dropped from this branch.

* feat(agent-trust): pre-trust the workspace for every preset agent at PTY spawn

Every Orca-started agent PTY passes through one of the two spawn builders
with its declared launchAgent, which survives setup-script wrapping. The
builders now call one hook that, for a fresh launch (never a reattach or
restored pane) with the setting on, applies the agent's trust preset to
the worktree, folder workspace or main checkout it starts in.

- One dispatcher, applyAgentWorkspaceTrust(preset, workspacePath, launch
  context), carries what a writer needs: the final spawn env, the Claude
  managed-account auth prep, the WSL distro and the SSH connection.
- Claude joins the presets on both the claude and claude-agent-teams
  entries. Its writer stays grant-only in claude-folder-trust-file.ts:
  the file Claude reads (CLAUDE_CONFIG_DIR / custom-OAuth suffix / legacy
  .config.json / a WSL guest's own file), Claude's <file>.lock never
  broken and taken only when a write is due, atomic temp+rename keeping
  mode and symlinks, never creating the file, NFC + realpath keys.
- SSH Claude launches forward the optional claudeFolderTrust spawn field
  so the relay grants with its own spawn env; old relays ignore it and
  Claude asks. Other presets keep the SFTP writer. A WSL launch never
  writes the Windows home: non-Claude presets skip it, Claude writes the
  guest's file or nothing.
- Codex keeps the 20 s deadline its shared config lane needs; every other
  preset gets 1.5 s. A miss means the agent asks; trust bookkeeping never
  fails or blocks a launch.

Removes the Claude-only machinery this replaces: the eligibility/host/
lifecycle/spawn modules, the persisted creation content-origin field and
its classification, revoke-on-removal, the setting-off sweep, the
claudeTrust.converge relay method and the Agent Teams leader special case
(the leader pane now spawns through the hook with the claude preset).
The agent config types move to tui-agent-config-types.ts so the config
table stays under the line budget.

* refactor(agent-trust): delete the pre-spawn trust writes the spawn hook replaces

The spawn hook is now the only owner of agent folder trust, so remove
every other writer:

- the agentTrust:markTrusted IPC channel, its preload bridge and types,
  and all renderer callers (agent-trust-preflight and its callers in the
  background session, work-item direct launch, session continuation,
  worktree creation, folder workspace composer and session fork);
- the main pre-spawn sites: the createdWithAgent preflight in
  worktree-remote.ts, markLocalWorktreeTrusted/markRemoteWorktreeTrusted
  and the runtime's markWorkspaceTrustedForAgent family with the
  markTrusted ports of the runtime create flows;
- Codex's own launch-prep and resume-prep trust writes.

Each of those launches reaches a spawn builder with launchAgent set, so
the hook covers it. This also fixes a live gap: the worktree-remote.ts
copy of the preset switch omitted Antigravity, so an agy agent started
from a desktop worktree create still asked; the single dispatcher covers
it. Trust is also written on the host the PTY actually spawns on, which
removes the #11163 class of writing the wrong host's config.

* test(agent-trust): type the spawn-builder trust fixtures and prove the spawn waits for trust

The builder test passed untyped args (a string launchAgent) and cast its deps,
which failed tc:node. It now builds both spawn states from a fully typed deps
fixture and a typed restored pane, with no casts.

Adds a case that holds the trust write pending and checks the builder does not
finish until it settles, the ordering the deleted renderer and launch-prep
tests used to cover.

* fix(agent-trust): give SSH trust writes the 20 s deadline again

The dispatcher gave every non-Codex preset a 1.5 s budget, including the SSH
writers for Cursor, Copilot and Qoder, which make several round trips over the
link. Before this PR those writes had 20 s (desktop) or no limit (runtime), so
on a slow link an unattended SSH worker would now stop at the agent's trust
question. SSH writes get the 20 s deadline back; local non-Codex writers keep
the short budget, and Codex keeps 20 s.

The relay's Claude grant keeps the short budget: it writes the relay host's own
disk and does not cross the link.

* fix(agent-trust): never pre-trust a home folder or a filesystem root

A folder workspace can be the user's home folder or a disk root. Claude and
Copilot let a trusted folder cover every folder under it, so pre-trusting one
of those would silently trust everything on the machine for those agents.

One check, isHomeOrFilesystemRoot, now refuses them for every preset: the
dispatcher checks roots and this machine's homes (including the spawn env's
HOME and a cached WSL guest home), the SSH writer checks the remote home it
already resolves, and the relay checks its own home. The agent then asks, as
it would without Orca.

* refactor(agent-trust): drop the Codex launch plumbing that only carried trust

The spawn hook replaced the trust writes in Codex launch prep and resume prep,
which left the fields that fed them unread: CodexHomeLaunchContext.workspacePath
and .launchAgent, the resume prep's workspacePath, and the structured Codex
launch input's workspacePath (plus the extra target lookup that produced it).
Remove them and their plumbing; unavailableManagedHomePath stays.

Also removes test stubs of runtime trust methods this PR deleted, whose
not-called assertions could no longer fail, and two comments that still
described the old trust preflight.

* chore(reliability-gates): point the trust gate at the spawn-time trust tests

The agent-session trust gate still listed three test files this PR deleted
(the renderer preflight, the Codex launch-prep deadline and the e2e trust
completion suites), so check:reliability-gates, which runs in PR CI and in
pnpm lint, failed on missing files. Its invariant also described the deleted
IPC handler and pre-spawn writers.

The gate now covers what replaced them: the spawn builders holding the spawn
until trust settles, the fresh-launch and setting gates, the per-preset
deadlines, and the home and root refusal.

* fix(agent-trust): skip the relay Claude grant for a WSL shell

On a Windows SSH host whose pane shell is wsl.exe, Claude runs inside the WSL
guest and reads the guest's config. The relay still granted trust in the
Windows host's own .claude.json, writing the Windows home for a WSL launch,
which the local path never does. The relay now skips the grant there, so that
Claude asks, as a local WSL launch does when Orca cannot reach the guest file.

* perf(agent-trust): only agent launches wait on the trust hook

Both spawn builders awaited the trust hook on every spawn, including plain
shells, reattaches and agents without a preset. Awaiting even a resolved
promise adds microtask ticks ahead of the pane-spawn reservation check, and
this handler already keeps non-Codex spawns off an await because an extra tick
reorders those reservation races.

The hook now returns null when there is nothing to write, and the builders
await only a real trust write.

* test(agent-trust): keep the home and root cases off any real Claude config

The home and root cases ran the real Claude writer with the test process's
env, so a regression in the guard would have written trust for the home
folder and / into whatever Claude config that env named. They now point
CLAUDE_CONFIG_DIR at a folder that does not exist, and the writer never
creates a config.

* test(runtime): drop needless casts from the launch-host test

The renamed launch-host test kept three `as never` casts on launch options
that already match launchAgentTerminal's parameter type. The changed-lines
casting gate reads the renamed file as new and failed on them.

* test(agent-trust): type the Claude grant mock with the real writer's signature

The mock took an unknown target, so installing the real writer as its
implementation would not typecheck under strict function types.

* fix(codex): drop the launch context the trust move left unread in local spawn env

* fix(agent-trust): queue Claude grants per config file so a launch burst keeps them all

Concurrent grants in one process retried Claude's file lock in lockstep, so each
retry round admitted about one winner. Starting 12 Claude agents at once left 6
of them at the trust question with nothing logged. Grants for one config file now
queue in-process; only Claude's own writes contend for the lock. The relay shares
the writer, so bursts of SSH launches are covered too.

* fix(agent-trust): never pre-trust a folder above a home either

The guard refused only an exact home or a filesystem root. A folder workspace at
/Users, /home or C:\Users was still pre-trusted, and Claude walks up parent folders
for a non-git folder, so every non-git folder in the user's home became trusted.
The guard now also refuses any folder that contains a home, on every host, and is
renamed to say what it decides.

* perf(agent-trust): skip the SSH round trips for Antigravity, which has no remote writer

Every Antigravity launch over SSH now reaches the remote trust writer, which
resolved the remote home and realpath'd the workspace over the link before
writing nothing (the known remote gap). That delayed each launch by two SSH round
trips, and up to the 20 s deadline on a stalled link. It now returns first.

* fix(settings): keep the hidden folder trust row out of web-client settings search

The paired web client hides the host-only "Trust the folder" row, but settings
search still listed it, so searching "trust" opened the Agents pane with no
matching row. Its search entry is now filtered the same way as Agent Awake.

* fix(agent-trust): a failing breadth guard skips trust instead of failing the spawn

* docs(qoder): New Tab now pre-trusts through the agent-wide spawn hook

* fix(agent-trust): never pre-trust a home reached through a symlink

Every trust writer stores the workspace's resolved path, but the breadth
guard compared only the path as given. A folder workspace that is a
symlink to the home folder (or a real home picked while HOME names a
symlinked one, as on distros that link /home to /var/home) passed the
guard, and Claude, Copilot and Cursor then trusted the home itself.

The local dispatcher and the relay now compare given and resolved forms
of both the workspace and each home. The SSH writer resolves the remote
home alongside the workspace, in parallel, so it adds no round trip.
Local non-Claude WSL launches still skip before any filesystem call.

* fix(relay): a failing breadth guard skips Claude trust instead of failing the SSH spawn

The relay ran its home/root guard and homedir() before its catch, so a
throw there rejected the relay's terminal spawn. Same fix as the main
dispatcher's: the whole grant, guard included, is best-effort.

* fix(agent-trust): guard the path each writer stores, not the path Orca was asked to trust

The breadth guard checked the launch's workspace while each writer stored a
transformed path, so every new transformation opened a hole. Codex stores a
linked worktree's main checkout: with a git repo rooted at the home, a Codex
launch in one of its worktrees wrote trust for the whole home.

One relay-safe host module now computes the stored path (Codex's main-checkout
hop, then given and resolved forms of it and of each home), refuses a root, a
home or a folder above one, and only then writes. Main uses it for local and
WSL launches and the relay for Claude. An unknown home writes nothing, and the
WSL home cache is keyed case-insensitively by distro.

* fix(ssh): the relay writes every preset's trust on the SSH host itself

Codex, Cursor, Copilot and Qoder trust over SSH was written from the desktop
over SFTP: four or five round trips per launch, so it needed a 20 s deadline
that outlasted the 8 s draft paste, the 10 s phone wait and the 15 s web-client
create. It also skipped Claude's atomic rename, ignored CODEX_HOME, and stored
the worktree where local Codex stores the main checkout.

The unreleased `claudeFolderTrust` spawn field becomes `agentWorkspaceTrust`,
sent for every preset. The relay derives the preset from the `launchAgent` it
already receives and runs the same host writer main uses, on its own disk,
within 1.5 s and with no extra round trip. Antigravity still returns early on
the relay (its writer is unverified on SSH hosts), a WSL shell still skips,
and any throw means the agent asks.

Deleted: the SFTP preset writer, the remote Qoder writer, the SSH deadline
clause and the desktop-side SSH root pre-check.

* test(e2e): keep CLAUDE_CONFIG_DIR out of isolated Electron launches

The spawn hook now writes Claude folder trust into the config
CLAUDE_CONFIG_DIR names, so an e2e run started from a shell that sets it
could add trust entries to the developer's real Claude config. Also drops
a stale comment that still named Codex launch prep as the trust owner.

* fix(agent-trust): guard Claude's resolve() form of the workspace too

Claude's writer stores both resolve(path) and the realpath. The breadth
guard compared only the given path and its realpath, so a workspace
path that does not exist and climbs back with `..` (for example
<home>/missing/..) passed the guard while Claude stored a key for the
home itself. The guard now also compares resolve(path), so it sees
every form a writer stores.

* test(relay): pty.spawn writes agent trust before the agent's process starts

Nothing exercised the relay handler's call into the trust writer, so
removing that call, or no longer awaiting it, left every suite green
while SSH launches silently stopped pre-trusting. The new case holds the
trust call pending and checks the spawn waits for it, and that the call
gets the request, the declared agent and the final spawn env.

The reliability gate lists the new suite and records the resolve() form
the breadth guard now compares.

* fix(agent-trust): refuse a home only for agents that inherit trust from it

The home and root refusal applied to every preset, so Codex, Cursor and
Antigravity started asking in a home folder workspace, where they did not
before. Only Claude, Copilot and Qoder let trust on a folder cover the
folders below it; Codex matches its start folder or that folder's repo
root, Antigravity the exact folder, and Cursor itself never inherits from
a home, a folder above one or a shallow path. The refusal now reads a
per-preset table in the host module, so the local and relay writers share
the rule.

* fix(agent-trust): trust Codex at the folder it starts in, as before

Before this PR, Codex launch prep trusted the spawn's start folder. The
spawn hook trusted only the workspace root and skipped terminals with no
workspace, so Codex began asking in a floating terminal and in a subfolder
of a non-git folder workspace: its lookup checks the start folder, then
that folder's repo root, and a plain folder above it is neither. The hook
now passes the resolved start folder for presets marked as keyed by it
(Codex only), falling back to the workspace root.

* fix(agent-trust): pre-trust a structured Codex chat's folder, as before

Before this PR, creating a structured (native) Codex chat pre-wrote Codex
trust for its folder through launch preparation. The PR removed that write
and routed trust through the PTY spawn builders, which a structured chat
never passes. Codex's app-server trusts the folder itself only when the
chat's permissions can write it, so a read-only chat started running
untrusted and ignored the project's .codex config. Creating the chat now
calls the same dispatcher, behind the same setting, before launch prep.

Brennan BensonandClaude 29c49aec31 feat(native-chat): hold mid-turn messages in a host-owned queue (#23726)
* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and
`queryWindowsProcessRowsFresh` lost their last caller with the handoff. The
fresh-scan tests now go through `queryWindowsProcessDescendants({ fresh: true })`,
the teardown path that still depends on that contract.

* docs(native-chat): stop citing the removed handoff in lifecycle comments

Six comments still named the handoff coordinator, a handoff suspend, or a
terminal-owned session as live participants in the flows they describe.

The removed restart handoff test pinned this branch; nothing else did.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

* refactor(native-chat): drop the transcript helpers only the handoff called

appendLegacyTranscriptMessages fed the terminal transcript catch-up and
proveClaudeTranscriptBranch backed the terminal owner's exit proof. Both lost
their last caller with the handoff. Their tests now go through the live entry
points instead: the roster bounds through the legacy import, the pinned-read and
growth tests through the ancestry replay the history window uses, and the marker
rules through the string proof in their own file rather than the session-file
resolver's.

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is
mid-handoff (<stage>)." in the composer. With the handoff gone, the stages that
reach it are a chat that is still starting, or one whose previous agent process
has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* test(native-chat): type the stand-in roster decoder without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* fix(native-chat): a Stop that names no turn stops what the conversation has in flight

Between handing a message to the agent and the agent opening its turn, there is no turn id a
client could name, so a Stop in that gap was refused as "already finished" while the agent went
on to answer. A cancel's turn id is now an optional precondition instead of its target: with
none, the host withdraws what is queued and, when the journal still reads working, asks the
adapter to stop whatever the child has in flight. Claude's interrupt is session-scoped, so it
is guarded by fence and acquisition generation rather than a turn identity. Codex interrupts
the turn its latest turn/start answered with until the journal shows one.

A cancel that names its turn behaves exactly as before.

* fix(native-chat): Stop is there from the moment a message is sent

The composer showed Stop only once the agent had opened a turn, so for the second or two after a
send the chat read "thinking" with no way to stop it. Against a host that takes a Stop naming no
turn, Stop now shows whenever the chat reads working (a turn, a queued message, or a handed-over
one still unanswered) or this client still has a message on its way. Pressing it, or Escape,
first drops every outbox entry the journal does not hold yet, so nothing goes out after the
Stop, then sends the conversation-wide cancel. A send already on its way reaches the host ahead
of the cancel, which withdraws it there. Against an older host Stop still needs a running turn.

The unconfirmed-send probe moves into its own hook so the outbox hook stays in budget.

* fix(native-chat): Stop before a turn is gated on its own host capability

A host that accepts sends first (agent-session.accepted-send.v1) can still predate the cancel
that names no turn and would refuse it as invalid, since clients and hosts ship independently.
Hosts that take that cancel now advertise agent-session.conversation-stop.v1, and the renderer
shows Stop before a turn opens, and sends the no-turn cancel, only to a host advertising it.
Every other host keeps a Stop that needs, and names, a running turn.

The host capability probe the accepted-send hook used is generalized so both read one path.

* test(native-chat): a build advertises conversation stop exactly where its cancel may name no turn

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* fix(native-chat): Stop reads the one working rule every session list reads

While Claude retries a rate-limited request it never echoes the message, so no
turn opens: the sidebar read Working from the unanswered send while the composer
showed Send. The chat's working state, the host's session-list status and the
host's no-turn Stop check now call one shared rule instead of three copies.

* test(native-chat): a rate-limit retry pins only that no turn opens, not how its rows are kept

* fix(native-chat): Stop leaves a message waiting on its Retry, and does not show for one

A send that failed holds the queue until the user retries it, and one the host restarted under is
parked the same way. Stop counted both as still on their way, so it showed in an idle chat and
could never go away, and pressing it dropped the failed message along with its Retry.

* test(native-chat): the chat's Stop and a session list read the main agent alike over their own copies

The chat reduces its stream and a list reads the status feed. Driven through the real host for a
rate-limit retry with no turn, a subagent still running after the main turn, and the handed-over
child exiting.

* refactor(mobile): the chat reads the main agent's working state through the shared rule

Behaviour is unchanged: the same two terms, now from the one function the host projection and the
desktop chat read.

* fix(codex): a Stop naming no turn never interrupts an earlier turn

It fell back to the id an earlier turn/start answered with when the latest start went unanswered,
or when the journal showed a compaction Codex had not started, and reported that as stopped.

* fix(native-chat): a Stop naming no turn never says a turn had already finished

When the provider found nothing left to stop, for instance a turn that ended between the host's
check and the interrupt, the chat got "The provider had already finished this turn." for a turn
the Stop never named. It now ends quietly, as a Stop with nothing in flight does.

* fix(native-chat): one Stop the host could not settle no longer refuses every later one

A Stop naming no turn has one operation key per session. When the host could not settle one, it
answered every later Stop under the same id as unknown until the id expired. Once the host says
so, the next press is a new Stop; transport doubt still replays the same id.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* test(native-chat): read Stop operation ids without a cast

* fix(native-chat): a Stop whose answer was lost no longer swallows the next one

A Stop that names no turn has one operation key per chat. When its answer was lost in transit, the
chat kept the id, so every later Stop replayed it; the host answers a replay as already handled, so
for up to a day Stop stopped nothing. The id is now dropped once the call settles, however it
settles. A second press while the first is still on its way still shares its id.

* refactor(native-chat): a Stop naming no target keeps its operation id only for its own call

The chat kept each write's operation id per payload across calls, and dropped it only on some
settle paths. That is right for a write naming what it acts on, but a Stop naming no turn, and a
stop of every background task, share one payload with every later one, so any path that kept the id
made the next Stop replay as already handled and stop nothing. One path was still open: an answer
that arrived after the chat moved to a new fence.

Whether a write names its target is now decided once, before its id is picked. One that names none
keeps its id only while its call is in flight, so a press made meanwhile joins it, and releases it
when the call settles, however it settles. The release runs only while the key still holds that
call's id, so a joined call settling late cannot drop a newer one's. This replaces the per-path
exceptions for a thrown call.

* test(native-chat): read the Stop fences without a cast

* test(native-chat): pin the new id for a named cancel the host could not settle

After the Stop naming no turn moved to a per-call id, the only test of the unknown-refusal release
was gone, and the half that stays, for a cancel naming its turn, could be removed with every test
green.

* fix(native-chat): a Stop pressed after a new message stops it, even while the last Stop is unanswered

A Stop naming no turn shared its operation id with any press made while it was still in flight. The
host runs a chat's writes in order, so a message sent between two presses was accepted after the
first Stop ran, and the second press replayed that Stop as already handled and left the message
running, although the chat had already withdrawn it from the outbox.

A write naming no target now gets a new id on every press and is never kept, so each Stop acts on
whatever is running when the host reaches it. A write naming its target keeps its id exactly as
before. A double press can ask the provider to stop the same turn twice, which it tolerates.

* fix(native-chat): Stop no longer blinks off as Claude opens the turn for a message

Claude's echo of a sent message both answers the send and opens its turn. The echo settled the send
first, so the host published the message as answered one frame before the turn it opened, and for
that frame the chat read nothing running: Stop turned back into Send, and Working blinked off in
every session list, for tens of milliseconds on each turn.

The echo now settles the send after the turn it opens has been emitted, so the running turn is
published first.

* fix(native-chat): a message a Stop withdrew comes back to its sender's composer

A Stop withdraws every message the host holds but has not run, and S also
drops the ones this client had not handed over yet. Either way the message
left the chat and its text survived only in a hidden journal row and the
in-memory ArrowUp history.

The sending client now puts the withdrawn text and images back in that
pane's composer, after whatever is typed there. Withdrawn is read from the
rejection reason through one shared check, which the outbox reconcile now
uses too. The composer is written before the entry leaves storage, so a
failure between the two repeats the text instead of losing it, and an entry
storage no longer holds is never given back again, so a replay, a second
view or a remount restores it once. Only this client's outbox holds the
entry, so other viewers still see the message disappear. A failed Stop
withdraws nothing on the host and gives nothing back.

* fix(native-chat): withdrawn text put back during an IME composition is not lost

While the IME owns the field, the composer ignores a programmatic draft, and
the next composed keystroke wrote the draft without the restored text, after
its outbox entry had already been dropped. The composer now holds text
appended mid-composition, keeps it in the cache after each composed write,
and shows it once the composition settles, the way attachments that land
mid-composition already wait for it.

* test(native-chat): pin that only a withdrawn message comes back to the composer

* test(native-chat): set up the composer's window API for every describe in the composition-race file

* docs(native-chat): note that the withdrawn check reads the legacy reason until a typed category lands

* test(native-chat): pin that text put back mid-composition shows once, even beside a mid-composition clear

* feat(native-chat): host-owned queued-message draft store in the session journal

A queued mid-turn message is a draft row in the session's journal.db,
created idempotently at every writable open with no user_version bump so a
downgrade stays writable. Consume converts one draft into an ordinary
submission inside the journal writer's own transaction (exactly-once), and
a standing writer hook returns a consumed draft only when a committed row
newly settles its current consumed submission to a non-withdrawn rejection
— the same decision the reducer folds rows through. Open-time repair
re-derives returned state behind the stored fact; retention never prunes a
row whose refusal could still return it.

* feat(native-chat): queued-messages wire contract, dark capability, and send classifiers

The send result becomes a union: today's submission arm unchanged, plus a
capability-gated queued arm only clients that sent delivery:'queue-if-active'
ever receive. Whole-list queuedMessages fields ride the subscribe events and
history pages; Stop gains withdrawQueued with the withdrawn bodies in its
result; clear's result carries withdrawn drafts too. Both classifiers treat
queued as accepted/spent. agent-session.queued-messages.v1 is defined but
deliberately NOT advertised: the rollout prerequisites (Claude fold receipt,
integrated Codex steer matrix) are not in this host.

* feat(native-chat): queue a capable mid-turn send as a draft, drain it at turn end, and let Stop and clear return its text

A send carrying delivery:'queue-if-active' while the session owes work — or
behind an actionable backlog — becomes a host-held draft instead of a
submission. A serialized drain woken by journal commits, draft mutations and
conversation opens re-derives its gates from live facts (streamed-event
barrier first, backlog never a gate) and converts the oldest actionable
draft through the exactly-once consume; from that instant today's delivery
pipeline runs unchanged. Stop pauses the withdrawable frontier at the stop
step (a process-level pause set that survives handle eviction and, via the
per-process host instance, restarts), then withdraws it with the text in the
result for capable clients; /clear does the same for the superseded source.
The draft list publishes whole per emit with identity dedup, rides only the
final catch-up page, and attaches to history pages. queuedMessageSend
overrides queue policy only; queuedMessageDelete hands the body back.
Replays for all of it answer from op-stamped tombstone receipts.

* test(native-chat): pin mid-turn queueing against the real host

Accept (working/backlog/text-only/budget/replay), the one-per-settle drain,
returned cards with N1 overtake and the N4 re-send loop, Stop withdraw with
tombstone replays, the process-level pause across evict/reopen, Delete
receipts, /clear returning the withdrawn text, and publication (hydration,
unchanged-cursor insert, same-frame consume, identity dedup).

* test(native-chat): read the queued receipt ids before the wait closures

* chore(native-chat): SAFETY rationales on the sqlite row casts and a cast-free mobile narrowing

* fix(native-chat): queued-draft bookkeeping never costs a publish, an open, a clear or a history read

- Cache the draft list per draft-table revision. The drain re-checks on every
  journal publish, so each streamed delta was running a SELECT and parsing
  every draft body the handle had ever written (tombstones included).
- Open-time repair/prune failures are reported and skipped; they no longer
  fail opening the chat.
- /clear on a source with no drafts answers exactly as before: no empty
  `withdrawnQueued`, no empty write transaction, no extra publish. A draft read
  failure after the committed clear no longer turns it into a refusal.
- History pages read drafts through the same guarded reader as subscribers.
- Publication moves to its own module; the held-draft rule lives with the
  pause state; one pending-prompt check; drop an export nothing calls.
- Tests: restart-held drafts, pre-consume failure pause + Send retry, failed
  open repair, clear with no drafts.

* fix(native-chat): a Stop that withdraws a consumed draft's send gives its text back

A queued draft converted into a submission leaves the sender's outbox, so when
a Stop withdrew that submission before the agent received it, the text had no
holder: the draft stayed `dispatched` forever and nothing restored it.

- The returned-card rule now follows every effective `rejected` settlement of
  a consumed draft's submission, a Stop's withdrawal included, with the
  withdrawal reason stored as the fact (`dispatchWasWithdrawn`). The writer
  hook and the open-time repair share the rule, so no rejected submission can
  leave its draft `dispatched`.
- A capable Stop withdraws the cards it returned itself along with its
  frontier, stamped with its caller-scoped key: the text comes back once in
  `withdrawnQueued` and replays from the tombstone. An old client's Stop
  leaves a returned card.
- Stop's draft steps move to structured-agent-session-queued-stop.ts.
- Tests: Stop between consume and the agent's receipt for both client kinds,
  its replay, a crash after the withdrawal, restart in the window, and the
  repair of a hookless withdrawal.

* perf(native-chat): the queued-draft drain takes no serialized step while the agent works

The drain was woken by every journal publish and, with a draft waiting, queued
a serialized step (streamed-event flush included) per publish, only to find the
session still working. During a streamed turn that is one step per delta,
contending with Stop and every other mutation for the session's queue.

The pre-check now also skips while the session is working. Whatever ends the
work is itself a commit that schedules again, and the step still re-reads every
gate after its flush, so no wake is lost.

- Test: queued sends during a turn take no drain step; settling the turn drains.

* fix(native-chat): a clear withdraws queued text only for a caller that can take it back; paused reasons are markers

An older client running /clear had its source's waiting and returned drafts
withdrawn and their text returned in a `withdrawnQueued` field it does not
read, so the text was lost. Clear now mirrors Stop: `withdrawQueued: true` on
`agentSession.conversationCommand` (strict params, sent only when the
queued-messages capability is advertised) withdraws the drafts and returns
their text once, replaying from the tombstones. Without it the source keeps
its cards: the supersession fence already blocks the drain, and Delete still
hands the text back.

A paused card's reason was host-authored English on the wire. It is now a
typed marker (`send_failed`) the client localizes, like `returnedReason`; a
client treats an unknown marker as a plain pause.

- Tests: an old client's clear leaves the cards and its replay stays
  field-free, then Delete returns the text; a capable clear returns the text
  once and replays it; the paused marker.

* fix(native-chat): a draft pause that commits no journal row still reaches live subscribers

A pause writes no journal row, so it reaches subscribers only on the next
publish. Two pauses had none behind them: the drain's pre-consume failure
(the session is idle by then, so nothing else commits) and an old client's
Stop that interrupted nothing. A live card kept reading as waiting, with no
failure marker, until some unrelated commit arrived.

The drain now publishes after pausing a draft it failed to convert, and an
old client's Stop publishes when it paused a frontier.

- Tests: a failed conversion and an idle old-client Stop each reach a live
  subscriber as a paused card; both fail without the fix.

* fix(native-chat): a failed clear wakes the queued drain, a failed Stop withdrawal still publishes its pause

A conversation command can settle on the record alone (a retried clear that
fails), so drafts held behind its prepared phase waited for an unrelated
journal commit; the command controller now re-derives the drain when any
command finishes. A capable Stop whose withdrawal write failed never
published the pause it set, and a publish failure after a committed
withdrawal (Stop or clear) dropped the bodies from the answer; publishing now
happens outside the withdrawal and can no longer discard its result. Tests
reset the process-level pause set between cases: operation ids repeat per
test, so a shuffled order held later tests' drafts.

* refactor(native-chat): the draft store notifies through the journal's commit listener, the hold is a stored row fact, and one typed gate decides every queue hold

R1: every standalone draft-table transaction that changed rows (insert,
withdraw, hold, open-time repair) fires the journal's own commit listener
after COMMIT, so a draft or hold change publishes and wakes the drain through
the same path a journal row does — no call site can forget. All hand-written
publish/wake plumbing for draft changes is deleted; wakeQueuedDrain survives
only as the record-input wake (a conversation command can settle on the
record alone).

R2: the process-level pause set becomes a hold_reason column on the draft row
(pre-ship, so no migration): holds survive eviction and restart, keep their
send-failed marker across restarts, die with the session's journal, and are
cleared by consume and withdraw in their own UPDATE. The host-instance
derivation stays the one restart mechanism.

R3: one typed structuredQueueHold (blocked | command | prompt | working)
consumed by admission, the drain step and Send-now, with each caller's
override set written beside it. A capable send during a late-result /compact
now queues instead of being refused (PLAN §3.1); the dead prepared-command
branches and the drain's duplicated gate list are gone. prompt outranks
working so Send-now's one override cannot swallow it.

R4: one isUnsettledQueuedMessage predicate for the withdrawable/budget
filters.

Loop 4: a replayed send whose draft was refused answers with the returned
card, never the rejected submission, so the text cannot render twice. Rewind
completion was verified to publish after the record clears (the rewind path's
own publish; the open path's recovery precedes the open snapshot).

* fix(native-chat): a Stop with no drafts writes nothing, and a failed hold still lets a capable Stop withdraw

The stored hold turned Stop's in-memory pause into a draft-table write, so
every Stop (drafts or not, capability advertised or not) opened a BEGIN
IMMEDIATE/COMMIT. An empty hold now returns before the serialized write.

A hold that threw also emptied the frontier, so a capable Stop withdrew only
returned cards and left the waiting drafts unheld to auto-send after the
interrupt. The frontier is read once and survives a failed hold.

* fix(native-chat): a capable Stop with no drafts writes nothing

The empty-hold guard from the previous fix did not reach withdraw, so every
capable Stop still opened a write transaction after the interrupt, and a
closed handle turned its empty answer into a missing field. The draft store
now answers an empty withdraw without a transaction, for every caller.

* refactor(native-chat): Stop and /clear never withdraw queued drafts; no text rides the wire back

Adopt the host-owned-queue model end to end: a Stop holds the waiting
frontier ('stopped') for EVERY client and interrupts — the cards stay
published as paused, Send-now overrides per card, and the pause dies when
the user next starts a turn (an ordinary dispatched send lifts 'stopped'
holds in the same serialized step; 'send_failed' holds still need their
explicit Send). /clear carries the source's unsettled drafts to the
replacement session as born-held rows — identical for every client
version — then tombstones the source. Delete answers with no body: the
card leaving the published list is the outcome.

Removed (never shipped; the capability was dark and unadvertised, so no
wire compatibility is affected): CancelParams.withdrawQueued and its
refine, ConversationCommandParams.withdrawQueued,
CancelResult.withdrawnQueued, ConversationCommandResult.withdrawnQueued,
AgentSessionWithdrawnQueuedMessage, the Delete result body,
settleStopQueuedWithdrawal and the cancel finisher,
withdrawClearedSourceQueuedMessages, replayWithdrawnQueuedMessages, and
cancelPlan's tombstone replay. This also removes the defect where a
withdrawal took every row regardless of which client sent it (a phone
Stop pulled desktop-typed text): nothing moves text anymore, so a Stop
from one client can never relocate another client's drafts.

Hold and carry writes are bookkeeping: a failure is logged and never
gates the interrupt or the clear.

* feat(native-chat): a restart hold lifts like a Stop's, and paused cards say why

The user's next dispatched send lifts every stop-shaped hold in one
UPDATE: stored 'stopped' rows, and restart-held rows (host_instance
mismatch), which are adopted into the running instance — the same fact
the derivation reads, so no second copy of the hold exists. 'send_failed'
still requires its explicit Send. Publication now marks stop/restart
holds with pausedReason 'stopped' (an additive optional value on a dark
capability), so clients can caption them "sends after your next
message" and keep "couldn't send" for 'send_failed'.

* fix(native-chat): only a client's own send lifts a Stop's queue pause

The lift ran for every accepted host send, so orchestration mail, a
restart continuation and a launch prompt released drafts the user had
stopped (and adopted restart-held rows into the running instance). The
client-facing agentSession.send RPC now marks its sends as the user's
own; host-internal senders leave the pause alone. Also drops comments
still describing the withdrawn return-text rule.

* fix(native-chat): a Stop's queue pause lifts when the user's send starts its turn

The pause lifted as soon as the host accepted a user send, so a send the
provider then refused (a failed child start, a refused turn/start) had
already released the stopped drafts into the same failure. The host now
remembers a client's own send, in memory, until the provider answers it:
acceptance lifts the stop-shaped holds, a refusal forgets it with the
holds intact, and a later Stop supersedes it. Nothing is persisted, so a
restart between the send and its turn start leaves the cards held for the
user's next send rather than sending them unasked.

* fix(native-chat): a consumed draft's turn starting lifts a Stop's queue pause

Drafts are only ever a client's own sends, so a drained draft or a
Send-now is a user send for the pause: its submission joins the same
in-memory set a direct send uses, and the provider accepting it lifts the
stop-shaped holds. Before, a message typed while a stopped turn wound
down drained as a draft and left the older stopped cards held, so their
"sends after your next message" caption was false. A refused consumption
lifts nothing, a later Stop still clears the set, and orchestration mail
and restart continuations still never lift.

* fix(native-chat): queue a capable send behind a /compact and re-scope /clear's carried drafts

- A text send with queue-if-active during a /compact in flight is admitted on the
  compact's side lane as a held draft instead of being refused; it may only become
  a draft, so one the gate no longer holds is refused rather than dispatched.
- Drafts /clear carries to the replacement are fingerprinted for the replacement
  session, so the provider's echo folds into the sent bubble.
- The in-memory set of user sends awaiting their turn is capped; sends settling
  unknown no longer grow it without bound.
- Correct the userSend comment: the renderer's launch prompt goes through the
  client RPC and does set it.

* fix(native-chat): a returned queued card carries the typed rejection fact, like a rejected submission

A consumed draft the agent never ran comes back as a returned card. The card
kept only the rejection's sentence, while its submission now also records the
typed fact a client classifies from. A host-restart rejection's sentence
carries no legacy marker, so such a card could not be told apart from a
provider's refusal.

The draft table stores the submission's fact next to its reason
(`returned_rejection`, written by the same settlement that sets the reason,
and read back with the reducer's own fact reader), and the card publishes it
as `returnedRejection`. Both are overwritten on every return, so a re-sent
card never keeps an earlier refusal's fact, and a /clear carry inserts a plain
held draft with neither.

Retention moves to queued-message-retention.ts to keep the table module
within max-lines.

* fix(native-chat): fit the queue to main's typed rejections and compaction result

Main (#23026) dropped the disposition's fresh-id retry field, gives a
rejected dispatch a typed sentence plus fact, and types /compact's result.
The queued-draft disposition and the queue tests now use those shapes.

* fix(native-chat): draft bookkeeping can never roll back the journal row it rides

The queued-draft returned transition runs inside every journal append's
transaction. A throw there (a draft table an earlier build created without the
returned_rejection column) rolled back the journal's own rejection row, so a
Stop, a failed start or a provider refusal could not be recorded. The standing
hook now runs in its own savepoint: its failure is logged and rolls back alone,
and the open-time repair re-derives the missed transition from the committed
row. The draft table also gains any missing nullable column at open.

* fix(native-chat): a draft a Stop or restart took back waits again instead of blocking the queue

Cards A, B and C wait; the turn ends and the drain consumes A, but the agent
has not taken it yet. A Stop then pauses B and C and withdraws A's submission,
which made A a returned card. The user's next send lifted B and C, yet a
returned card blocks everything behind it, so B and C never sent although they
read "sends after your next message". A restart or close before hand-over did
the same.

Nobody failed the user there, so the draft now goes back to waiting at its own
position, under the hold that same event put on the drafts behind it: a Stop's
'stopped', or no stored hold after a restart, whose hold derives from the host
instance. It carries no refusal, and records its spent submission id in
consumed_as, so its next consume (the drain, or Send on the card) mints a fresh
id through the same path a returned card's re-send uses. Provider refusals and
other failures still return the card. The live settlement hook and the
open-time repair share one decision. After a Stop and the user's next turn,
A drains first, then B, then C, one per turn.

* fix(native-chat): Delete and Send on a queued card answer at once during a /compact

A /compact holds the chat's serialized lane for its whole provider call, and
the queued-card Delete and Send ran on that lane, so both hung until the
compaction finished. They now run on the side lane a draft-only send already
uses while a compaction is in flight: Delete completes at once, and Send
reaches its readable "wait for the conversation operation" refusal at once.
The drain stays on the main lane and keeps its command hold, so nothing sends
until the compaction settles.

* fix(native-chat): a re-sent returned card drops the refusal it came back with

Re-consuming a returned card left returned_reason and returned_rejection on the
now-dispatched row, so the row described a refusal that no longer applied. The
consume clears both in the same update that moves the card to dispatched.

* perf(native-chat): the queue gate reads pending prompts without rendering the journal

The prompt check ran on every send admission and drain step, and read
journal.snapshot(), which copies and sorts every item in the chat. It now walks
the reduced items in place with journal.visitItems; the answer is the same,
since the snapshot only sorts those items.

* fix(native-chat): a Stop that fails leaves the queued cards as it found them

Stop holds the waiting cards before it withdraws queued sends and interrupts
the agent. When a later step threw or the Stop was refused, the cards stayed
paused ("sends after your next message") although a failed Stop is meant to
change nothing. A failed Stop now undoes exactly what it added: each card it
held gets back the hold it replaced, a consumed card its withdrawal sent back
to waiting is released, and the user sends it had set aside can again lift the
pause. Holds an earlier Stop or a restart put on the cards stay.

The hold SQL moves to its own module, and the draft store's standalone
transactions share one helper.

* docs(native-chat): confirmed cancellation is no longer a queue rollout prerequisite

Stop withdrawing queued sends with a typed cancellation landed on main with
#23026. The comment gating the queued-messages capability now lists only what
remains: the Codex steer matrix (#21062), the Claude fold receipt, turn-owner
bars, and the desktop and phone clients.

* docs(native-chat): the Claude fold receipt and turn-owner bars have landed; Codex steer and the clients remain

* fix(native-chat): Send on a queued card during a /compact is refused before it takes a lane

Send-now chose its lane once, at entry. During a /compact it took the side
lane, where it could wait behind a Stop, then run after the compaction had
settled and append a real submission unserialized against the main lane.
While a compaction is in flight, Send-now is now answered with the "wait for
the conversation operation" refusal before entering any lane, and otherwise it
runs on the main lane. Only Delete keeps the side lane, whose compare-and-set
withdrawal is safe on either.

* fix(native-chat): a Stop that fails after reaching the agent keeps the queue paused

A failed Stop undid its queue holds whenever it threw, including after the
interrupt had already gone to the provider (a status-note write failing after
cancelTurn, or after stopping a starting agent). The turn could be stopped
while the cards drained as if no Stop was pressed. The Stop now marks the step
that reaches the provider, and undoes its holds only when it failed before
that. A Stop the agent refused answers ok and keeps its holds; the comment no
longer claims otherwise.

* fix(native-chat): a skipped draft settlement heals on the next drain step, not only at reopen

The draft settlement rides each journal append as bookkeeping, and a failure
there is logged and skipped. Only the open-time repair re-derived it, so a
consumed draft whose submission was rejected stayed dispatched (invisible, and
blocking nothing it should) until the chat reopened. The re-derivation is now
its own function, shared by the open-time repair and the drain: whenever a
dispatched draft's submission is already rejected, the drain step applies the
owed settlement first.

* fix(native-chat): one id is never recorded as a submission twice

A second submission row under an id the journal already holds replaces the
submission with a fresh pending one, so a rejected message could be handed
over again under its own id. Send on a queued card could do exactly that: if
the host died after it consumed the card under the operation's id but before
its answer settled, the rerun consumed again under the same id.

The journal now refuses a submission under an id it already records, so no id
is delivered twice whatever the caller does. And a Send-now rerun that finds
the card consumed under its own operation id answers with that submission
instead of consuming again.

* fix(native-chat): a waiting draft whose first send the agent echoed is withdrawn, never resent

A consumed draft goes back to waiting when its submission is rejected as never
delivered (a Stop's withdrawal, a restart, a close), and then sends again
automatically. That rests on the "never delivered" claim. If the provider then
echoes that message, the first delivery happened, and the automatic resend
would give the agent the same message twice.

The reducer already keeps such an echo apart, since a rejected submission may
not claim it, so the draft store reads it from the appended row itself: a
provider echo of a user message that no live submission claims, matching a
waiting draft whose spent submission is rejected, withdraws that draft the way
a Delete would. The echo-claiming rule is split out of the reducer's aliasing
so both read the same decision, and the per-row draft hook moves beside the
settlement re-derivation.

* feat(native-chat): a submission names the queued draft it hands off

Clients told a queued card's hand-off apart from other sends by comparing the
draft's id with the submission's id. That holds only for a draft's first
hand-off: a re-send, or a draft that goes back to waiting and drains again,
goes out under a fresh id, and the clients showed the card and the sent
message together, or restored text the host still held.

Every submission the host creates by handing off a draft now carries
queuedMessageId, the draft's id. It is written on the submission's journal row
as an optional key (older readers keep it and ignore it), carried by the
reducer, listed in the published submission schema (which otherwise strips
it), and stamped where the row is built from the consume itself, so no
hand-off path can leave it off; a caller naming a different draft is refused.
A direct send names none. The queued-messages capability comment makes the
link part of v1.

* refactor(native-chat): every queued draft goes out under a fresh submission id

A draft's first hand-off reused the draft's own id as the submission id, so
comparing a draft id with a submission id looked right in every first-send test
and failed only on a re-send or a requeued draft. Every hand-off now uses a
fresh id (the drain mints one; Send on a card uses its operation's id), so id
equality is never true and a reader must use the submission's queuedMessageId.

The host gets simpler: queuedMessageNeedsFreshSubmissionId is gone, consumed_as
is set on every dispatched row and cleared when a withdrawal sends the draft
back to waiting (its spent submissions stay findable by their link), the
consume refuses the draft's own id, and the consumedAs ?? messageId fallbacks
collapse. The delivered-echo check finds spent hand-offs by link.

A send this host queued, asked again (a lost answer's replay, or a rerun the
operation ledger no longer covers), answers from its draft and then from the
hand-off that names it, through one function. The rerun path used to be kept
from sending twice only because a submission sat under the send's own id;
with fresh ids that guard is now explicit. A Send-now rerun recognises its own
consume by the link instead of consumed_as.

* fix(native-chat): an echo withdraws a draft only if its rejected hand-off reached the agent

The delivered-echo rule withdrew a waiting draft when a provider echo matched
any rejected hand-off of it, including one a Stop rejected before it was ever
handed over. That hand-off is provably unwritten, so a matching unclaimed echo
is some other message, and the rule silently deleted the card. Only a hand-off
that was handed over and then rejected as never delivered can be disproved by
an echo now.

* fix(native-chat): a skipped echo withdrawal is re-derived before the draft can send again

The delivered-echo withdrawal rides each journal append as bookkeeping, and a
skipped hook left the draft waiting, so it later sent the same message a
second time. Nothing re-derived it. The draft store now also withdraws, in its
owed-settlement pass, each waiting draft that an echo already in the journal
proves delivered: an unclaimed provider user message (still stored under its
own id), carrying the draft's payload, appended after a hand-off that was
handed over and rejected. The live hook and the re-derivation share one
predicate. The pass runs at open and in the drain step, right before a draft
would send; it reads every item, so it never runs per streamed row.

* fix(native-chat): a rolled-back journal append leaves no draft state cached

The draft store caches its row list by revision. The per-row hook read that
list eagerly inside the append's transaction, after the consume in the same
transaction had already written and bumped the revision, so a failed COMMIT
left the cache showing a hand-off that never happened. The hook now reads the
drafts only once a row holds an unclaimed echo, and any rollback of a journal
append or of its bookkeeping savepoint invalidates the cache, so no other read
inside the transaction can leave it stale either.

* fix(native-chat): a replay of a deleted queued card answers withdrawn, not refused

Once a deleted card's tombstone is pruned, a replay of the send that queued it
found the draft through its last hand-off. When that hand-off had been
rejected (the card came back, and the user then deleted it), the replay
answered with the rejected submission, which clients show as a failed send
with a Retry. Only a withdrawn row is pruned while its last hand-off stands
rejected, so the replay now answers queued, withdrawn.

* refactor(native-chat): name the queue's pause-lift for what it releases

* chore(native-chat): one import of the mutation helpers

* feat(native-chat): a Stop pauses the whole queue, derived from the journal, with an explicit Resume

After a Stop, each waiting card was held on its own row ('stopped'), lifted
when the host saw, in memory, that a user send made after the Stop had its
turn accepted. The cards read "sends after your next message" one by one,
there was no way to resume the queue without sending something, and the
in-memory record of user sends was lost on a restart or eviction.

The pause is now the queue's, and derived rather than stored as a flag:
- 'stopped': the user's last Stop took effect at a recorded journal position
  and no turn a person asked for has started since. "A person asked for it"
  is the new `origin: 'client'` on the submission row (a send over the client
  send RPC, or a card they sent now); orchestration mail, a restart
  continuation, a host-sent launch prompt and the queue's own drain record
  `host` and never lift it.
- 'restarted': a waiting card was written by another host process and no
  person's turn has started since this conversation opened.
Resume (`agentSession.queuedMessagesResume`) lifts either. Send-now sends one
card; the rest stay paused until that card's turn starts, which is a person's
turn like any other.

The journal's row kinds are closed (an older build truncates a journal at a
row kind it does not know), so the one event the journal cannot carry, where
the Stop took effect, is recorded beside the drafts in `queued_message_pauses`;
everything after it is read from the journal. A Stop records it only once it
takes effect (after withdrawing queued sends, as it reaches the agent), so a
Stop that fails first leaves nothing to undo, and the per-row hold, its undo
and `userSendsAwaitingTurn` are gone. A card keeps a hold of its own only when
its conversion failed ('send_failed').

The pause is published once, as `queuePause` beside `queuedMessages`, on live
frames, catch-up and history. A /clear starts its replacement paused, as after
a Stop, since the carried cards were written for the context it discarded.

* feat(native-chat): a /clear's replacement queue reads paused because of the clear, not an interrupt

The replacement's pause was recorded as 'stopped', which clients show as
"Queue paused because you interrupted" although the user cleared the chat.
It is now its own reason, 'cleared', on queuePause.reason
('stopped' | 'restarted' | 'cleared'). It lifts and resumes exactly like a
Stop's: through Resume, or the user's next turn starting on the replacement.

* fix(native-chat): a queue pause covers only the cards it paused

A Stop recorded its pause fact even when the queue had no cards, and the fact
outlived the cards it did pause. The published list hid a pause over no cards,
but the drain still treated the queue as paused, so a card typed much later —
during an orchestration-mail turn, or a correction typed before the stopped
turn ended — sat under "paused because you interrupted" with no Stop of its
own.

A Stop now records its pause only if the queue holds a card when the Stop takes
effect (the hand-offs its withdrawal sent back included). The fact is retired
in the same transaction as the Delete, consume or withdrawal that empties the
queue, never from an async publish. A /clear's carry now lands each card with
its 'cleared' pause in one transaction, so a failed insert leaves no pause over
an empty replacement.

* perf(native-chat): the queue's pause reads the latest person's turn in O(1)

The pause is derived on every publish, per subscriber, and each derivation
copied and scanned every submission to find a person's accepted turn after the
Stop. The reducer now keeps that fact as it folds rows: the submission row of
the latest accepted turn whose origin is `client`. The Stop's and the
restart's lift both read it directly.

* fix(native-chat): a card handed off after a restart belongs to the process that sent it

A draft's host_instance was only ever the process that first wrote it (or
adopted it while waiting). A returned card from before a restart, sent again
in this process and then withdrawn back to waiting, still carried the old
process, so it raised a 'restarted' pause although no restart happened since
it was sent. Every hand-off (the drain, Send on a card) now stamps the
handing-off process on the draft in the consume's own update.

* fix(native-chat): a queue pause shows only while Resume would send something

After a Stop whose only remaining card was a returned one, or after a restart
with only a card held by its own failed send, the queue published a pause with
a Resume that could send nothing: a returned card waits for the user anyway,
and a held one for its own Send. The pause is now published, recorded by a
Stop, and kept only over a card it can hold back — waiting, with no hold of
its own. The fact is retired in the same transaction as the write that removes
the last such card, a hold or a refusal included.

The publication's dedup also compared only the pause's reason, so a pause
appearing or clearing with no readable reason could read as unchanged; it now
compares presence first.

* fix(native-chat): a queue pause counts only cards Resume would actually send

A waiting card behind a returned one is blocked until the user acts on the
returned card — the drain never sends past it — so a pause over only such
cards still offered a Resume that sent nothing. The rule for "a card Resume
would send" is now one function: waiting, no hold of its own, and not behind a
returned card. The publication, a Stop's record and the fact's retirement all
read it; retirement reads the rows in position order inside the same
transaction as the write that took the last such card.

* fix(native-chat): a returned card that blocks the paused cards hides the pause but keeps it

The last change retired a Stop's pause as soon as a returned card blocked every
paused card. Deleting that returned card then sent the cards behind it at once,
with no Resume — not what the user asked for.

The two rules are now separate. The pause is KEPT (recorded by a Stop, retired
in the same transaction as the write that takes the last one) while any waiting
card with no hold of its own exists, wherever it sits. It is PUBLISHED only
while such a card is not behind a returned one, so the header never offers a
Resume that sends nothing. Deleting the blocking card shows the pause again,
and the cards behind it wait for Resume or the user's next turn.

* fix(native-chat): a Stop pauses a card its withdrawal sent back even when that settlement was skipped

The Stop checked the draft table for a card to pause. When the per-row hook
that settles a withdrawn hand-off was skipped, that card was still
'dispatched', so the Stop recorded no pause; the drain later healed it back to
waiting and sent it, although the user had pressed Stop. Retirement had the
same blind spot and could drop a pause while such a card was owed.

What a pause holds back is now one predicate, judged inside the transaction
that records or retires it: a waiting card with no hold of its own (one SQL
EXISTS), or a dispatched card whose consumed submission was rejected with a
settlement back to waiting (read against the journal's submissions). The Stop
first runs the owed settlement, as the drain does; if that fails, the owed
card still counts, so the pause is recorded rather than skipped. recordPause
now checks inside its own transaction and returns whether it recorded, and any
draft-table write (and the per-row hook, the consume and the open-time
repair) retires a pause that no longer holds anything back.

* test(native-chat): pin the per-row hook's pause retirement; skip the judgement when no pause exists

The retirement test recorded its second pause over a queue with nothing to hold
back, so the recording returned false and the "retired" assertion proved
nothing; ablating the per-row hook's retirement passed every test. The hold
case now asserts the pause was recorded, and a new test has a delivered echo,
through the per-row hook, withdraw the last card a recorded pause holds back.

Retirement runs on every appended journal row, so it now checks the pause row
by key first and judges nothing when no pause is recorded. Two comments were
brought in line with the owed-hand-off rule and rewrapped.

* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and

the teardown path that still depends on that contract.

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

A send refused because the chat's owner is not settled showed "The session is

has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* fix(native-chat): the conversation outlives its agent

Opening a chat no longer starts its agent. A conversation is reached through one host
accessor that opens its journal at rest, and a send is what starts the agent, through
the delivery loop. One idle sweep, every five minutes, stops an agent that has been
quiet for thirty minutes and owes no work, then drops an open journal handle that is
only a cache. Its record, tab, status row and readers stay.

- hold and release are no-ops; hold still builds the host for shipped mobile builds.
- The holders, the holds, the release clock and the exit respawn are deleted.
- Options, the model list, the goal and the context meter answer at rest; a model pick
  at rest is recorded as intent for the next start.
- Compact, rewind, clear and goal changes start the agent first. A send does too when
  a rewind is still in doubt after the conversation opens.
- Orchestration routes mail and group addresses on ownership (the record plus the chat
  tab), not on whether the process runs. An open dispatch keeps its worker running.
- The restart continuation is a send; Resume all holds each slot until the message is
  handed over or rejected.
- A read error never replaces a loaded transcript, and shows the host's own words.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* fix(native-chat): a request that failed reads as failed

A structured chat whose only message the agent's start refused read as a
green finish, and a cancelled structured turn did too: the host published a
verdict only for turn records, and structured rows carried no `interrupted`.

The host projection now reads the session's latest request: its turn's
outcome, or `failure` for a send the agent or its start refused. A send
that was withdrawn, or left undelivered by a restart or a close, fails
nobody and makes nothing listable. The ingest publishes `interrupted` as the
hook lanes do, and every reader decodes the verdict through one accessor, so
a failure reads Failed on the dot, the rollups, history and `worktree ps`,
behaves like a cancellation in every clean-finish policy, and notifies as
"failed".

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): a verdict change republishes the mobile status projection

* refactor(native-chat): the store's retention trigger keeps its flag compare

A verdict change always moves the completion clock the same check already
reads, so a second verdict compare there caught nothing new.

* test(native-chat): a user message the provider journaled keeps its session listed

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* fix(native-chat): a restart offer ends when the chat's agent starts again

The offer used to end only when the chat's newest user message changed,
because opening a chat started its agent and that start could not be told
apart from real activity. Opening a chat starts nothing now, so the host
reads the fact it already publishes: a chat's status row goes from not
host-owned to host-owned exactly when its agent is started. At that edge the
offer and any failure record for the chat are withdrawn, unless the start is
a resume action's own (its continuation is the oldest undelivered message).

A continuation and a message racing to be first are decided at acceptance:
the continuation is refused, quietly and with nothing filed, when any other
message was accepted since the restart. A failed continuation start leaves
the offer retryable, and each resume action sends its own message id.

Deleted: the newest-user-message comparison, its journal reader, the
continuation filter, and the failure ledger's own "answered by the chat"
check. The marker still carries its message id for one release, so the
previous build can read it.

* fix(runtime): end a transcript stream when its client unsubscribes

Desktop: the IPC subscription controller was dropped as soon as the streaming
handler returned, which for most streams is right after it binds. A later
runtime:unsubscribe then found nothing to abort, so the host kept the subscriber
and derived and sent every publish to a channel no one listened to. The controller
now lives until the renderer unsubscribes, resubscribes the same id, or goes away.

Mobile: disposing an agentSession.subscribe stream now sends agentSession.unsubscribe
with the stream's frame id, so the host ends that subscriber and leaves a sibling
stream on the same socket running. The direct path now passes the frame id the relay
path already passed.

* fix(native-chat): a late provider-session update keeps a failed recovery record failed

A provider-session heartbeat that rewrites a completed recovery record kept
its interrupted flag but dropped the outcome it was copied with, so a live
failed checkpoint read as a clean finish until the next status write.

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* test(native-chat): the terminal-bell check asserts the renamed verdict field

The bell notification test still checked for agentInterrupted, which no
longer exists, so it could not catch a verdict leaking into a bell dispatch.

* fix(native-chat): a failed turn ranks like a completion for attention

Attention readers (completion time, Smart Sort, sticky retention, Cmd+J
Recent) now demote only a turn the user stopped. A failure is news the
user has not seen, so it keeps its completion time, ranks in the Done
class, stays retained after its pane goes away, and a retained failure
reads failed in the worktree rollup instead of done. Clean-finish
policy (hibernation, pane ownership, the value moment) still treats a
failure like a stop.

The retention trigger compares verdicts again: success -> failure no
longer moves the completion clock.

* fix(native-chat): one fact ends a restart offer: the chat moved on since the restart

The offer is live while no other message has been accepted in the chat since the
restart and its agent has not proved a start since. The offer list, the resume's
reservation check and the continuation's acceptance check all read that one fact,
so a message whose start then failed withdraws the offer too, and a stale click
finds nothing to act on.

The fact is read off the conversation's open handle, which the restart closed, so
it is retired durably whenever it may have changed: a message accepted, a start
proven. A close and reopen within the same run therefore cannot bring the offer
back. A continuation rejected before it reached the agent does not count, so a
retry after a failed start still runs.

Deleted: the quit-time gate on withdrawal, which changed nothing because the
withdrawal and the quit's own offer write share one queue; the per-action
"withdrawn" flag and the separate acceptance check it paired with.

* test(native-chat): an older build reads the restart offer this build records

The offer lives in a file the previous release reads after a downgrade. Pin that
against the pinned release's own capsule, and run the lane when the marker or the
capsule changes.

* fix(native-chat): read a restart offer against where the journal stood when it was taken

"Since the restart" was read off the conversation's open handle, which the idle
sweep closes: after a reopen, a message the user had already sent looked older
than the handle and the withdrawn offer came back.

The offer now records the journal position (epoch and sequence) at the moment
it is taken, and a message accepted after that position, or a journal on another
epoch, means the chat moved on. That is derived from the journal, so it holds
across any number of closes and reopens. An older build's offer has no position;
only a start withdraws it. Because the message half is now durable, the offer is
no longer rewritten in the recovery file on every accepted message; a proven
start still writes it, since only the host that saw the start knows of it.

* test(native-chat): wait for the listing's retire write before reading the recovery file

* refactor(native-chat): every journal row states which turn it belongs to

Rows gain a turn scope stated by the write that creates them: the open root
turn, or the conversation. A queued message takes its scope from its handover.
Rows stored before scopes existed are placed on replay by the root turn open
when they were created, so no persisted state is needed for them. Rewind keeps
each retained row's scope and producer, so a subagent's row stays its own.

* fix(native-chat): keep the terminal-backed chat's read error over its local echoes

Messages winning over a read error is right for the structured chat, whose read retries and whose
messages came from the transcript. The terminal-backed view assembles its list from local echoes
too (a launch prompt, a pending send), so a failed read there showed only those bubbles and no
error. Only the structured pane now keeps messages over an error.

* fix(native-chat): a start retries the exit settlement a failed journal write left owed

An agent exit whose journal settlement write failed releases the lease latched until a retry lands.
Reopening the chat used to be that retry; with reveal now only opening the journal, nothing retried
it before the next app launch, and every send was refused. The start the send needs now runs the
retry first, where the attach would.

* fix(native-chat): a failed main agent reads failed while its subagents still work

The verdict is now read from the main agent's own state, not the folded
row: a main agent that is done and failed has a verdict even while its
subagents keep the row working. Without mainAgent (history, worktree ps,
older hosts) the old combined-done rule stands.

Display marks the verdict through agentVerdictDisplayMark: a failure
outranks every combined state on the agent's dot, label, tab badge,
dashboard and activity rows; a stop marks only a done row, so a
successful or stopped main agent with live subagents still reads
working. Subagent rows keep their own state. The worktree card, terminal
tab and Cmd+J rollups share one pane fold and rank a pending question,
then failed, then working, monitoring, interrupted and done.

worktree ps publishes the main agent's outcome on a working row, and the
mobile mirror reads it. The store's change check, the paired-client
mirror's equality and its epoch now see a verdict change on a working
row, which otherwise moves no state or clock and left the worktree card
reading working. Clean-finish policy is unchanged: a working row is never
hibernated and has no completion time.

* perf(native-chat): answer the owner check without opening the chat

Worktree activation calls agentSession.handoffStatus for every chat tab in the worktree, and the
answer comes from the session record alone. Reaching it through the accessor opened each resting
chat's journal (a full read, the crash-boundary write and a restored status publish), then kept it
open for the idle window. It now checks the record and the adapter's support, as before this series,
and opens nothing.

* fix(native-chat): a read waiting on the session lock opens nothing once quit began

The accessor checked for quit before queueing the open, so a read queued behind a session task ran
its open after teardown had begun and indexed a journal no teardown step would close. The check now
runs at the open itself.

* test(native-chat): pin stated turn scopes, the upcast of unscoped rows, and rewind attribution

* fix(native-chat): /compact is a message the chat sends, run as a turn of its own

The conversation command RPC now accepts /compact into the queue like any
send and answers once it is handed over. The delivery loop opens the command's
own turn, starts the provider on it, and waits for the provider's end off the
session's queue, so messages typed meanwhile are held and delivered after it,
even when it fails. It settles by re-reading the journal: a child that died
meanwhile already wrote the verdict. Stop ends the command at once. The 180 s
completion window, the unconfirmed row and the recovery of an older build's
compaction record are gone; that record no longer gates anything. On Codex the
provider turn the command opens is claimed into the command's turn.

* fix(native-chat): read a failed resume's chat before calling it retryable

Whether a failed resume is retryable is the offer's own rule: the chat has not moved on since the
restart, read from its journal. The failure list read it only for a chat already open, so once the
idle sweep closed a chat the user had moved on in, its failure showed Retry again, and the click did
nothing. The list now opens the failed chats first, as the offer list does.

* test(native-chat): type the provider event sink the settlement test reaches for

* docs(native-chat): the worktree ps outcome comment no longer claims old hosts send it

The field is new: an old host sends no outcome at all, so a reader falls
back to interrupted. The removed clause said old hosts send it on done
rows, which never shipped.

* fix(native-chat): say the structured read keeps trying only where it does

The structured pane's "Orca keeps trying to load it" line never showed: the view state filled in an
untranslated fallback whenever the read error had no text, and the empty state prefers any message.
The view state now leaves the message out, so the structured pane shows that line and the
terminal-backed pane its own translated one. Mobile's structured lane does not resubscribe after an
error frame, so it no longer makes the claim.

* fix(native-chat): rows group under the turn their record names, not the one above them

Each row's turn is the turn its stated scope names, anchored on the entry
that opened it, or on the turn itself when the provider opened it unasked.
So /compact groups its own rows and the previous turn is untouched, a message
typed into a running turn joins it, and a provider-resumed turn folds under
its own Worked-for. A row reporting how a turn ended, an error or the
compaction separator, never folds. Desktop and mobile read the same keys; a
host that states no scope keeps today's positional grouping.

* test(native-chat): await the send's settlement instead of polling for the start

The at-rest send tests polled for the provider start with vi.waitFor's one-second default, which a
loaded machine outran. They now await the host's own settlement of the message.

* docs(native-chat): the status-store listing rule names provider-journaled user messages

* fix(native-chat): a restart offer resumes any time after the quit, and knows its own continuations

The continuation's message id was dated by the quit, and the ledger refuses a new id dated more than
a day back, so Resume or Retry a day after quitting was always refused (on main too). It is now
dated by the resume action.

Telling a rejected continuation from the user's own message read the operation ledger, whose rows
expire after about a day; after that a failed resume stopped being retryable. The offer now
records the continuation each action sends on its own capsule entry, bounded to the newest 16, so
the ids end with the offer. The ledger read is deleted.

* fix(native-chat): a /compact is not a request the sidebar, notifications or restart resume report

The sidebar's prompt, preview, verdict and instant, the turn-completion feed,
and the restart-resume marker read past a conversation command and its turn to
the last real request, so a /compact neither notifies nor re-dates the row,
and a command in flight is never offered as work to resume. An older client
shown a command's turn in the legacy form names the session's own agent.

* fix(orchestration): route no mail to a structured worker its orchestration released

A structured worker is routed on ownership, and a resting worker's lease is released, so ownership
held while its chat tab stayed listed. A worker the coordinator abandoned and then released, found
at rest by the release, therefore still took peer mail and @worktree: broadcasts, and each one
restarted its agent. Routing now also reads the orchestration's own resource row: once it is
released, direct mail, group addressing and worker-show's addressable answer drop the worker, as
they would a terminal worker whose terminal closed. The chat tab stays, and nothing new is stored.

* fix(native-chat): a failed retry names the user's prompt, not Orca's continuation

A resume's continuation is written to the chat before its start, so after a failed attempt the chat's
newest user message is that rejected continuation. A second failure then showed Orca's own restart
text as the chat's prompt. A retry now keeps the prompt its first failure named.

* test(native-chat): pin what a conversation command's admission refuses at rest and at handover

* test(native-chat): tests merged from the base state which turn their rows belong to

* fix(native-chat): a refused send notifies failed through the completion feed

The host's completion feed followed only the newest turn, so a send the
agent or its start refused, which creates no turn, read Failed on its row
but sent no notification. The feed now follows the session's latest
request, read from the projection the status feed already makes for the
commit: a turn keeps its id, a refused send is named by its journal item
key. It announces only while the session is idle, as the row reports a
verdict, so queued sends refused one commit at a time notify once, and a
withdrawn send falls back to a request already announced.

* fix(orchestration): read the released row optionally, as the authority does

worker-show's observation called the row lookup directly, which a runtime double without it threw on
and failed the structured tab-retirement release.

* chore(native-chat): one import per module and no unexplained casts in the turn-scope changes

* test(claude): pin which turn a Claude row joins, including a subagent's after the turn ends

* fix(native-chat): the status bar drops a restart offer the chat moved on from

The renderer re-read the host's restart offer only when a failed chat showed activity, so after a
message withdrew a pending offer the host answered no chats while the status bar kept counting one,
and clicking it opened nothing. The same watch now covers pending offers: a status change in an
offered chat asks the host again, once.

* fix(native-chat): a refused steer is read from the turn its handover named

The latest-request reader decided whether a refused send had joined a running turn by comparing
host clocks: its handover time against the previous turn's end. The handover row now states the
turn it delivered into, so the reader reads that instead and the clock comparison goes. A journal
written before handover rows stated a turn is scoped on replay from the turn open when each row
was written, which can differ from the clock reading only when a send and a turn's end share a
millisecond.

* fix(mobile): the native-chat controller contract carries the turn journal

The controller and overlay already pass nativeChatTurnJournal, but the
contract type never declared it, so mobile failed to typecheck.

* fix(native-chat): the live turn is the running turn, not the newest user row

A turn the provider opened on its own (a background wake, a resumed turn)
anchors on its own record, but the list still treated the newest user row
as the live turn. While such a turn ran, the settled user turn before it
lost its duration and the running turn's own rows were drawn as settled,
so its tool calls lost their live state.

nativeChatTurnMembership now answers both questions from the turn record:
each row's turn, and the live turn (the running root turn's anchor, else
the newest user row, which is also all an unscoped host has). Desktop and
mobile key liveness, the timing clock and the live status's row on it.

* test(native-chat): a turn the provider opened keeps its own clock

Pins that the local turn clock follows the live turn, so a wake after a
settled turn does not restart that turn's clock when no host durations
are recorded.

* fix(native-chat): a running turn no message opened draws its status on no row

Its live status belongs to the transcript-tail indicator alone. Once it
settles, its duration draws at its first row as before; a running turn a
message opened still draws on that message.

* fix(native-chat): every copy of a row carries the main agent's own status

History entries, sleep records and `worktree ps` rows carried a flattened
top-level `outcome`, copied under different gates and without the main agent's
clock. They now carry `mainAgent` (state, outcome, stateStartedAt), the type
the live row already persists and sends, and every copy site takes it with
`interrupted` through one function, `agentVerdictFields`.

- The accessor reads `mainAgent` then the legacy flag; the mobile mirror
  matches it line for line.
- Sleep records admit `mainAgent` with `normalizeMainAgentStatusField`, so a
  malformed value drops the field, never the record.
- Mobile dates a main agent that failed under live subagents by its own clock,
  as desktop does, and its row equality compares `mainAgent`.
- The activity feed reads a history entry's own `mainAgent` instead of
  rebuilding one; the sync key and history equality compare it.

* test(native-chat): pin the worktree ps verdict across host and phone versions

Pairs the real v1.4.212 host and phone row reader with this build: an old phone
reads a new host's rows by `interrupted`, a new phone reads an old host's rows
(no `mainAgent`) the same way, and a new phone reads a failure under live
subagents as Failed, dated by `mainAgent.stateStartedAt`. The release checkout
now carries the phone's self-contained row reader, and the lane runs when the
`worktree ps` row producers change.

* test(mobile): name the parity table's row for its role

* test(native-chat): a roster of idle or finished children does not keep an agent awake

The sweep reads owed background work through the shared child-work liveness that upstream's
release clock adopted; a child that went idle or finished is not work the agent still owes.

* fix(native-chat): a request that settles while the user is asked something notifies once

The completion edge waited for an idle session, and a pending prompt (including a
subagent's approval) is not idle. Structured chat has no other attention producer,
so a main turn that finished while a subagent waited on the user sent nothing
until the prompt was answered.

The edge now waits only on owed work (a running turn or an unanswered send), which
the projection reports even beneath a pending prompt. A request that settles with
a prompt pending announces once; the renderer words it "needs input" from the
host status mirror's `attention`, and answering the prompt keeps the same request
identity, so it does not announce again. The wire shape is unchanged.

* fix(orchestration): a task dispatched into a resting structured worker keeps it running

The sweep's open-dispatch check read only the worker-start dispatch that owns the worker's terminal
resource, so a task later dispatched to the same worker (orchestration dispatch --to, which writes a
dispatch with no worker row) did not count: after thirty quiet minutes the worker was stopped while
that task was open, and its coordinator read exited. Any unsettled dispatch addressed to the worker's
process incarnation now counts, derived from the existing rows.

* fix(native-chat): a command's wait ends when its child does

The delivery loop waited for a /compact only on the adapter's compaction
tracker, which learns of the child's end only on some exit paths: a Codex
exit or close, and a Claude close, never reach it. The wait then never
ended, so nothing queued behind the command was delivered again, Stop had
no child to answer through, and the tracker's leftover entry refused the
next /compact.

Every way a child ends passes endProviderChild, so the host now offers a
per-child end signal there. The loop races the tracker against it (the
dead-generation settlement has already written the command's verdict),
and on that end asks every adapter to release the command, so a later
command runs and no later provider turn is claimed into the dead one.
The adapters' own exit-time releases were unreachable (Codex) or covered
one path of several (Claude), and are removed.

The Codex RPC test harness moves to its own module so the exit can be
driven through the real adapter's connection callback.

* fix(native-chat): keep refusing sends during a command on an older host

An older host's controller still refuses a send while a conversation
command runs, so dropping the client's block turned every message typed
during /compact into a 'not sent' row with Retry there. The block stays
for hosts that do not run the command as a send-path turn, and goes only
for those that do.

The signal is one the client already holds: a host that runs /compact on
the send path states a turn scope on every journal row it writes, the
same fact turn membership uses to tell it from an older host. Both now
read it from one predicate. On an empty conversation, or one whose rows
all predate the upgrade, the signal is absent until the command's own
entry streams in, so that brief window keeps the old local refusal; no
capability or wire field is added.

* docs(native-chat): comments stop describing the hold this PR removed

Eight comments still justified orderings and teardown choices by a viewer or dispatch hold that
pinned the provider child. Nothing holds any more; the orderings stand for the binding's redrive
subscription and parked mail, and a chat's agent runs from a send until the idle sweep rests it.
Comment-only.

* fix(native-chat): the completion says when the user is being asked

A request that settles while a prompt waits on the user was worded "needs input"
from the renderer's status-feed mirror. Remote clients receive the status and
completion streams over separate sockets, so they can arrive in either order and
the wording could be wrong both ways.

The host already knows at emit time, so the completion now carries an optional
`awaitingUser: true` in that case and omits it otherwise. The renderer words the
notification from that field alone and no longer reads the status mirror. Old
clients ignore the field and word by outcome; old hosts never send it.

* fix(native-chat): a restart offer keeps the start its own continuation made

Whose start ended an offer was decided at read time, from whether the offer's continuation was
still the queued message. Once the provider refused that continuation, the child it had started
read as someone else's start, so the offer ended and its failure showed no Retry. The delivery
loop now records which queued message a start is for on the in-memory child, and the child's end
carries it; the offer counts a start as its own when that message is one of its continuations.

* fix(native-chat): a rewound turn still names the message that opened it

A Codex rewind rebuilds the epoch without submissions, so each sent message survives only under
its provider key. The kept turn records still named the submission key, so each turn anchored on
itself and its rows grouped apart from the message that opened it. The rewind now renames the
turn's opener along with the message.

* fix(native-chat): Stop ends only the command it names

Stop on a command turn abandoned whatever compaction the session had pending, so a late Stop for
an earlier /compact cancelled the one running now. The tracker now ends a command only when the
Stop names its turn, and the cancel reply reports whether it did.

* fix(native-chat): an agent gets a full idle window after its owed work ends

The sweep measured quiet only from the last journal row, so once a subagent, command, monitor or
dispatch that had outlived the window ended, the agent was stopped at the next tick. A child can
read done before the lead's wake-up turn writes anything, and stopping in that gap loses the
wake-up. The sweep now counts owed work it observes as activity, which gives the agent the full
window afterwards, as the release clock it replaced did.

* test(claude): the options-read fixture runs a live child

The fixture marked its conversation running with a hasProviderChild field the
session type does not have, so the read took the at-rest path and refused a
session with no record. It now carries a child, which is what the read checks.

* test(native-chat): host tests reach its collaborators through a typed seam

The rest-test rig and three test files read the host's private members with
Reflect.get and cast the result. The host now exposes one test-only accessor,
collaboratorsForTests(), and the subscribers class a subscriberCountForTests()
beside its existing retainedActivityCountForTests(), so the tests are checked
against the real types and the casts are gone.

* fix(worktree-status): a departed agent's failure yields to live work on the worktree card

A retained failed agent has no expiry, so ranking it with a live failure pinned the card to Failed over other panes' live work. It now ranks below working, monitoring and permission, and above every finished outcome.

* refactor(orchestration): one owner answers a structured worker's custody

Routing, group addressing, worker-show and the idle sweep each composed their own reading of
whether orchestration still holds a structured worker, so each new obligation or retirement state
had to be added to every reader. structured-worker-custody now derives both answers from the
worker-terminal list state coordinators see in worker-list: addressable is owned and not released,
and owed work is an active custody or an unsettled task dispatched to the same incarnation. The
owner's state is read through the remote dispatch attachment too, as the terminal transfer lookup
already does. Behaviour is unchanged; a settled worker awaiting its coordinator still rests.

* refactor(orchestration): owed work is an open dispatch on the worker's incarnation

A supervised worker's own dispatch context stays open exactly while the worker is active, so the
separate active-custody branch only repeated it. Owed work is now one fact, which also states the
policy that a worker awaiting its coordinator's decision may rest, and both custody decisions are
written once at the top of the module.

* docs(agent-status): a departed agent's failure ranks below live work on the worktree card

* fix(native-chat): a restart offer knows its continuations by a tag in their id

The offer recorded each continuation id in a list on its capsule entry, capped at 16, and a running
action's id in memory. Both could disagree with the journal: past the cap an old rejected
continuation read as the chat moving on, and a crash during a retry restored the failure's older
entry, which lacked the retry's id. Each continuation id now carries a tag derived from the offer
(its teardown and chat), then the action's own part, so any continuation of this offer, queued or
rejected, is recognised from the journal row and the marker alone. The persisted list, its cap and
the in-memory action map are deleted; the agent-start withdrawal keeps an offer whose own
continuation the start was for, read against the stored marker.

* test(runtime): the legacy-worker reveal test judges its stale snapshot inside the wait

The tui-idle probe reads through readTerminal, which now awaits the structured
worker check before the PTY read, so the probe's snapshot request starts a
microtask later. vi.waitFor missed it on its first check and polled again at
50 ms, the same moment the wait's own 50 ms timeout fired. The stale snapshot
then resolved after the wait had already timed out, so the test passed without
judging it, and the rejection landed before any handler was attached. Vitest
reported that as an unhandled error and failed the shard.

Polling every 1 ms sees the request within a few ms, so the snapshot is judged
while the wait is still pending.

* fix(native-chat): a message held behind /compact is drawn where it was handed over

A message typed while /compact runs was drawn above the compaction's result, between
itself and its own answer. The reducer kept every item at the sequence and timestamp of
the row that created it, and a queued message is created at acceptance, long before the
command it waits behind writes its result. The phone orders by that sequence and the
desktop by that timestamp, so both put the message first.

A queued message now takes its position from its handover row, the same row that already
states its turn scope. Everything the agent did before the handover, a command it waited
behind included, draws above it. This holds for every held message, not only /compact's,
and needs no client change: every client, older builds included, reads the position the
host publishes. A live batch already carries the item when its dispatch row lands, and
history pages cut the reduced timeline by sequence, so paging stays contiguous.

* fix(native-chat): a phone's send during /compact answers without waiting out the compaction

A client that predates accepted-send replies, which is every phone build, has its send
reply held until the host hands the message over. A message sent during /compact is not
handed over until the compaction ends, so the phone's 15 s request timeout fired first
and showed the message as unconfirmed.

That wait now also ends once the message is queued behind a running command. This is
read from the journal's running turn and needs no new state. Every other wait still
ends at the handover: behind a starting child or an ordinary turn, and for restart
resume, the command front door and orchestration, which keep the plain handover point.

* perf(native-chat): a rewind places provider items with one pass over the merged rows

A Codex rewind gives each provider item the old epoch never held the turn record for its
provider turn. It found that record by scanning every merged row, restoring each row's
body, once per provider item. That is quadratic, and it runs on the host's main thread
up to the journal's 10,000-row cap, twice per rewind. A rewind record written before
rows carried their scope holds no scope for any provider item, so it paid the full cost.

The merge now indexes turn records by provider turn id once, keeping the first match as
the scan did, and each provider item looks its record up.

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* fix(native-chat): a message waiting behind /compact is drawn after it until it is sent

A message sent while /compact runs is placed where it was handed over. It was still
drawn where it was accepted until then. /compact writes its result one step before the
handover, so for that step the waiting message sat above the compaction's separator.

A message the host accepted but has not handed over is not part of the conversation
yet, so both clients now draw it after everything the agent has done. The shared
projection moves it to the end, which is the order the phone draws. The desktop ranks
it with the other not-yet-sent rows, after the streaming preview. At handover it takes
its place from its handover row, which is also after the separator, so it never
appears above the compaction it waited for.

* fix(native-chat): the idle sweep reads owed work every tick

Owed work counted as activity, but the sweep read it only once the idle window had elapsed, so it
refreshed the clock at most once a window. Work that ended just before the next read left the
agent to be stopped at that read, moments after the work ended, which is the gap the refresh was
meant to cover. The sweep now reads owed work on every tick for a started agent, so the window
always runs from the last tick that saw work owed.

* fix(native-chat): a continuation handed to the agent stays sent

The offer read its own continuation as not reaching the agent while its dispatch was pending, which
also covered one already handed over and still unanswered. When the wait for that answer ended first,
the failure it filed read as retryable, and a retry sent a second continuation to an agent that may
have acted on the first. Only a continuation still queued, or rejected, is now read as unsent.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(cross-version): load the phone row readers without mobile's toolchain

Vite transforms a file against its nearest tsconfig, and mobile/tsconfig.json
extends expo/tsconfig.base.json, which the root-only cross-version lane never
installs. The worktree ps verdict suite imported the current phone row reader
from mobile/ directly, so CI failed with TSConfckParseError before any test ran.

The harness now imports a copy of the working-tree reader placed under the
checkout cache, where the root tsconfig applies, as it already does for the
release checkout's copy. Both readers are still the real files.

* test(cross-version): keep the checkout path-guard message and justify the copy import's cast

* fix(native-chat): a command ends only by its own provider answer or its child's end

Stop no longer settles a conversation command. It interrupts it like any turn,
and when the provider cannot take that (Codex has not opened the command's turn
yet, or Claude refuses the interrupt) it stops the child, whose dead-generation
settlement writes the verdict.

The pending command now lives on the provider child's own session instead of an
adapter-wide map keyed by session, so it dies with the child and nothing has to
release it. Claude's /compact is sent under a uuid the slot records, and only a
root result naming that input (or naming none) ends it; its outcome is read with
the ordinary result reading, so a stopped /compact is a cancellation.

* fix(native-chat): a command's settle answers its message before ending its turn

The two writes are not one batch. Writing the message's answer first means a
crash between them leaves a running command turn, which the stale-turn sweep
already settles, instead of an ended turn whose message reads as in flight
forever. The settle now writes only while the command turn is still running.

* fix(native-chat): "Worked for" counts from the handover, not the send

A message held behind /compact, or behind a cold start, used to count the wait
as the agent's work, although its row is drawn at the handover. Every handed-over
submission's turn, the command's own included, now starts at the handover row's
instant, falling back to the send time for a host that recorded none.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): the interrupted create's own retry continues again

The merge of main's lease-latch fix replaced that test's retry of the interrupted create, under its
own operation id, with a fresh start whose result nothing read. That fresh start passes with the
released-reservation continuation deleted, so the case the fix exists for went untested. The retry
and its assertion are main's again.

* docs(native-chat): three comments that still had views starting agents

A start with nothing queued now comes from a command, goal change or rewind; an interrupted compaction
left alone would refuse every send, so no agent would ever start to finish it; and a current host
raises the unattached read refusal only once quit began, with the attach window belonging to an older
host.

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* fix(native-chat): a second Stop on a command ends its child; one compaction verdict for every provider

A Stop's note now names itself in its key, so a later Stop on a command still
running reads, from the journal, that the provider was already asked and never
answered, and stops the child instead of interrupting again. Nothing is held in
memory for it.

Adds the rule both translators will read a compaction's end by: only a
compaction the provider reported is a success; none after Orca's interrupt is a
cancellation; anything else is a failure. A real Claude capture, pinned as a
fixture, is why: a stopped /compact ends in the same success result as a
finished one.

* test(native-chat): a reader's open settles the turn a failed exit settlement left running

An exit whose settlement write failed leaves its turn running in the open journal. PR 1's open now
settles it, and this pins the two reads that reach it here: a reader reopening a chat the idle
sweep closed, and a read that opens the chat before the restart restore reaches it.

* test(native-chat): the view-start test's starting window outlasts two subscriptions on a loaded runner

A subscription reads the conversation before it returns, so under load the two views took longer
than the create child's 300 ms start, which then exited before the test checked that it had not.
The child now takes a second to fail.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* refactor(native-chat): the provider's translator ends a command's turn; the loop holds no command state

A conversation command is now a turn of the provider child's own journal
pipeline. The adapter-wide tracker, its promise and the loop's settle step are
gone.

- Codex: the translator claims the provider turn that carries the command, scopes
  its rows to the command's turn, and writes the command's end in the same batch
  that settles that turn. Codex's own compaction marker is the success row.
- Claude: the command's turn is the translator's open turn until the result that
  answers the /compact input ends it. The command's own frames, such as the
  continuation summary, its echo and "Compaction canceled.", draw nothing.
- Both read the end with the one compaction rule: success needs the provider's
  report of the compaction; none after Orca's interrupt is a cancellation.
- The message resolves at the provider's receipt, as any send does: the Codex
  ack, or the Claude slash-command waiter on its result. The host writes a
  command's end only when the provider never took it.
- The delivery loop stops while a command's turn runs, and every journal commit
  re-wakes it through the session's serialize, so an end that lands while a step
  decides to stop is never lost. A child that ends first is settled with it.

* test(native-chat): pin a command's end to real /compact frames and to each path it threads

The captured /compact frames drive the Claude translator's command turn: a
finished compaction ends as a success with only the separator drawn; a stopped
one ends as a cancellation with no failure row, and the next send answers in its
own turn; a result naming another input ends nothing. The command's end is
checked at each point the ordinary result path threads through: the reopen latch
after a failure, the settling of a child still working, the context facts the
result reports, and the provider's own error row.

On the host: a message held behind a command is handed over when the command
ends just as the loop stops for it, a refused command settles as a failure and
the loop moves on, and a Claude child that exits mid-command settles the command
and hands what waited to a fresh child.

* test(native-chat): tests merged from the base state which turn their rows belong to

* refactor(native-chat): drop the child-end waiter nothing waits on

A command no longer waits for its child here: its turn ends from the provider's frames or from
that child's settlement, and the delivery loop is woken by the commit. The waiter and its test
were left from the earlier shape.

* fix(native-chat): a command holds the queue only while its child runs it

The delivery loop stopped whenever the journal showed a command's turn running. When the
command's child ended and its settlement could not be written, that turn stayed running with
no child to end it, and the loop's gate kept it from ever starting the next child, which is
what settles a gone generation's leftovers. Every later send was held for good, and Stop had
no child to end.

The gate now holds only while the conversation has a child: with none, the command belongs to
a gone generation, and the loop's start settles it like any turn a dead child left running.

* fix(native-chat): a Claude /compact succeeds only on its compaction boundary

The command's evidence counted Claude's `compact_result: 'success'` status as the compaction
done. That status comes before the boundary that replaces the history, so a Stop landing
between the two read as a finished compaction even though no boundary was ever written. Only
the boundary now counts, as the rule for both providers states; the capture's finished
compaction carries one, so it still reads as a success.

* fix(native-chat): a Claude child's exit says why the turn it ended stopped

When a Claude child exited mid-/compact, the command showed "Worked for 0s" and no reason. The
child's translator ends its open turn the moment the exit is reported, stamped with the exit's
instant, so by the time the exit settlement ran nothing was running. The settlement recognises a
turn the exit already ended by that same instant, but the Claude lifecycle event dropped it on the
way to the host, which then used its own clock, matched nothing, and wrote no row. When the clocks
did agree, the row was scoped to the running turn, of which there was none, so it landed outside
the turn it explained.

The exit's instant now reaches the host, and the exit row belongs to the turn the exit ended:
still running, or ended by the translator at that instant.

* fix(native-chat): a message waiting behind /compact draws below its live activity

A message sent while /compact runs waits on the host until the command ends. Both clients moved
it to the end of the transcript rows, but the running turn's live activity line ("Compacting the
conversation") draws after every row, so the waiting message sat between the command and its own
live status.

A row that is queued, and not what the live turn is for, now draws after that live activity: on
desktop outside the transcript window, below the activity line; on the phone in the list footer,
below the live status. A message whose own start is pending still draws above the activity that
start reports.

* fix(native-chat): only a running command holds a message below its live activity

A message is accepted, then handed over a moment later, and in between it reads as waiting. Every
message waiting behind a live turn drew below that turn's activity line, so an ordinary message
sent while the agent was working crossed below "Thinking" and jumped back up once it was handed
over, on desktop and phone. Only a conversation command's turn holds the queue on the host.

A message now waits below the live activity only while the running turn is one a command opened,
read from the entry that opened it. The phone test also typechecks, which the mobile test ratchet
requires.

* test(codex): the claim test names its notification params as a record

* test(native-chat): a read that reaches a crashed chat before the startup reconcile settles its turn

On desktop the chat on screen at relaunch reads before startup reconciles the leases, while the
dead process's lease still reads live. The open settles the turn it left running anyway, and the
restore that follows finds it settled.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* docs(native-chat): drop the removed dispatch hold from six comments

A worker's session no longer takes a dispatch hold, and no release clock
rests a chat by visibility; the agent-launch comments, the abandon test,
the teardown test and the refusal census still said so.

* test(native-chat): rest the owner-status chat through the idle sweep, not a hold

The activation-gate test from #22808 put its chat at rest by holding and
releasing it, and passed the release-clock grace. This branch deleted both,
so the case threw before it reached its assertions. It now moves the host's
clock past the idle window and lets the sweep stop the agent and close the
conversation, then asserts the same owner answer and activation gate.

* fix(native-chat): show the structured pane's retrying line when a read fails

The read transport always hands the pane the host's words, so the error
state's "Orca keeps trying to load it" line, which showed only when there
were none, was never seen: the pane showed the host's text twice, as its
subtitle and on the status line under it. The structured pane now always
says its read keeps retrying, and the host's text stays on the status line.
The terminal-backed chat is unchanged.

* fix(native-chat): a send the provider never received after a restart has no verdict

Restart reconciliation rejects a crash-stranded send that is absent from a
trustworthy provider history with reason 'not_delivered'. Nobody failed that
send, but the verdict allowlist did not name it, so after a crash the chat
read Failed, was listed, and could notify "failed". Give the reason a shared
constant (persisted value unchanged), add it to the no-verdict set, and treat
it as an internal marker so the Retry row no longer shows the raw string.

* fix(native-chat): a failed Codex compaction's late completion writes no turn of its own

Codex ends a failed turn with an error and then still completes it as failed.
The error settled the compaction and released its claim on the provider turn,
so the completion read that turn as an ordinary one and wrote a stray record.
The claim now lasts until the completion, which adds nothing to a command the
error already ended.

* test(native-chat): the mid-command exit case resumes its next child as a real one does

The case's fake started every child as a newly created thread with the same generation. The
store refuses a created link once the conversation has a thread, so the next child's start
failed and wrote its own error row, which landed before or after the case read the journal.
The next child now resumes the thread under its own generation, and the case reads the
journal once the waiting message is delivered, which also proves the loop moved on.

* test(native-chat): wait for a send's background start before the refusal oracle removes its store

An accepted send wakes the delivery loop, which starts the agent in the background. The oracle's teardown disposed the loop but did not wait for that start, so its lease write could create a temp file in the store directory while the directory was being removed, failing the test with ENOTEMPTY about one run in four. The teardown now drains tracked starts before it closes the journals.

* fix(native-chat): a start a message waited on gets one failure row, the delivery loop's

When a queued message's start failed, two writers could report it under the same row: the delivery loop, when the adapter settled the start without proving it, and the exit settlement, when the child's exit landed. The last one won, so the chat's row could name a different cause than the one the message was rejected with, or be written twice.

The exit settlement now writes the start's row only when no message is queued and the loop has not already recorded that start. A start for a command, goal change or rewind, with nothing queued, still gets its row from the exit.

* fix(native-chat): a /compact whose start failed says to run /compact again

The failure-words context named only /clear as a command to retry, so a
/compact whose agent failed to start read "Send your message to try again."
on its row, its rejected message and the command reply. The context now
carries any conversation command; the host derives it from the oldest
message still waiting on the provider, which is the one a failed start
fails first, and the /compact reply names it directly.

* fix(native-chat): a Codex /compact ends only on its turn's completion, below Codex's own error row

Since only turn/completed ends a Codex turn, Codex's turn-ending `error` is a row
inside the still-open command turn, and the failed completion that follows it is
the command's end: completed, outcome failure, at the completion's receipt time.
The command's own "Compaction failed" row was written on that completion too, so a
failed /compact read its reason twice.

The command turn now notes when Codex's turn-ending error for the turn it carries
was written as a row, and its end then adds no second row. A retried stream error
ends nothing and is not counted. The flag that let the error end the command and
kept the claim until the completion is gone with the error-driven end.

A test replays the captured failed compaction from the real app-server through a
claimed command turn.

* test(native-chat): main's crash-turn test states its row's turn, and a dead /compact settles on its recorded exit

Two tests the main merge brought together:
- The crash-turn test from #23456 writes a turn record through the event sink
  without options; every row here states its turn scope, and a turn record's is
  the thread.
- The /compact whose exit settlement could not be written no longer stays running
  until the next start: main now settles an open chat from the exit it recorded, so
  the command reads interrupted before the next message, which is then delivered.

* test(native-chat): main's new journal tests state each row's turn

The crash-turn, stale-turn and sink-queue tests main added wrote rows without a
turn scope, which every item write now states. Rows written inside a running
turn name that turn; the sink-queue batch and a send handed over with no live
turn name the thread.

* fix(native-chat): draw a queued turn's message after the earlier turn's rows

A message sent while A runs is written to the journal when it is sent.
When the provider queues it (Claude answers it after A), A's remaining
rows - its last tool run and its answer - are written after that
message, and the message's own turn opens only after them. Grouping put
those rows in A's turn, but the transcript still drew them in journal
order, below B's bubble and bar, where A's answer read as B's reply. This
is the residual #23671 left open.

A message that opened a turn now draws after the earlier turns' rows the
journal wrote after it, just before its own turn's rows
(nativeChatTurnDrawOrder, returned by nativeChatTurnMembership as
drawOrder). Desktop and mobile both draw in that order. A steer, and a
message that has opened no turn yet, stay where they were written. It
applies on hosts that state turn scopes and, through journal order, on
older ones.

* test(native-chat): run #23026's Stop tests against #23059's command turns

Two of #23026's tests call APIs #23059 changed, and failed after the
merge:

- codex-structured-conversation-stop: a compaction now goes through
  adapter.compact with the command run the host wrote (#23059), not a
  bare turn id, and answers with the provider's receipt. With the command
  claimed, a Stop that names no turn while the compaction's provider turn
  has not opened still interrupts nothing.
- main-agent-working-agreement: a provider row states its turn scope
  (#23059's appendItem contract); the retry and subagent rows are
  conversation-scoped.

* fix(native-chat): typecheck main's Stop and restore-grouping code against #23059

A Stop's compaction interrupt reads the narrowed requested turn, and the
restore-grouping test states whether each row reports its turn's outcome.

Brennan BensonandClaude c49388cd33 fix(native-chat): Stop is there from the moment a message is sent (#23026)
* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and
`queryWindowsProcessRowsFresh` lost their last caller with the handoff. The
fresh-scan tests now go through `queryWindowsProcessDescendants({ fresh: true })`,
the teardown path that still depends on that contract.

* docs(native-chat): stop citing the removed handoff in lifecycle comments

Six comments still named the handoff coordinator, a handoff suspend, or a
terminal-owned session as live participants in the flows they describe.

* test(native-chat): type the stalled snapshot drain without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* test(native-chat): pin that a start dead before proving owes no settlement

The removed restart handoff test pinned this branch; nothing else did.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

* refactor(native-chat): drop the transcript helpers only the handoff called

appendLegacyTranscriptMessages fed the terminal transcript catch-up and
proveClaudeTranscriptBranch backed the terminal owner's exit proof. Both lost
their last caller with the handoff. Their tests now go through the live entry
points instead: the roster bounds through the legacy import, the pinned-read and
growth tests through the ancestry replay the history window uses, and the marker
rules through the string proof in their own file rather than the session-file
resolver's.

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is
mid-handoff (<stage>)." in the composer. With the handoff gone, the stages that
reach it are a chat that is still starting, or one whose previous agent process
has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* test(native-chat): type the stand-in roster decoder without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* fix(native-chat): a Stop that names no turn stops what the conversation has in flight

Between handing a message to the agent and the agent opening its turn, there is no turn id a
client could name, so a Stop in that gap was refused as "already finished" while the agent went
on to answer. A cancel's turn id is now an optional precondition instead of its target: with
none, the host withdraws what is queued and, when the journal still reads working, asks the
adapter to stop whatever the child has in flight. Claude's interrupt is session-scoped, so it
is guarded by fence and acquisition generation rather than a turn identity. Codex interrupts
the turn its latest turn/start answered with until the journal shows one.

A cancel that names its turn behaves exactly as before.

* fix(native-chat): Stop is there from the moment a message is sent

The composer showed Stop only once the agent had opened a turn, so for the second or two after a
send the chat read "thinking" with no way to stop it. Against a host that takes a Stop naming no
turn, Stop now shows whenever the chat reads working (a turn, a queued message, or a handed-over
one still unanswered) or this client still has a message on its way. Pressing it, or Escape,
first drops every outbox entry the journal does not hold yet, so nothing goes out after the
Stop, then sends the conversation-wide cancel. A send already on its way reaches the host ahead
of the cancel, which withdraws it there. Against an older host Stop still needs a running turn.

The unconfirmed-send probe moves into its own hook so the outbox hook stays in budget.

* fix(native-chat): Stop before a turn is gated on its own host capability

A host that accepts sends first (agent-session.accepted-send.v1) can still predate the cancel
that names no turn and would refuse it as invalid, since clients and hosts ship independently.
Hosts that take that cancel now advertise agent-session.conversation-stop.v1, and the renderer
shows Stop before a turn opens, and sends the no-turn cancel, only to a host advertising it.
Every other host keeps a Stop that needs, and names, a running turn.

The host capability probe the accepted-send hook used is generalized so both read one path.

* test(native-chat): a build advertises conversation stop exactly where its cancel may name no turn

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* fix(native-chat): Stop reads the one working rule every session list reads

While Claude retries a rate-limited request it never echoes the message, so no
turn opens: the sidebar read Working from the unanswered send while the composer
showed Send. The chat's working state, the host's session-list status and the
host's no-turn Stop check now call one shared rule instead of three copies.

* test(native-chat): a rate-limit retry pins only that no turn opens, not how its rows are kept

* fix(native-chat): Stop leaves a message waiting on its Retry, and does not show for one

A send that failed holds the queue until the user retries it, and one the host restarted under is
parked the same way. Stop counted both as still on their way, so it showed in an idle chat and
could never go away, and pressing it dropped the failed message along with its Retry.

* test(native-chat): the chat's Stop and a session list read the main agent alike over their own copies

The chat reduces its stream and a list reads the status feed. Driven through the real host for a
rate-limit retry with no turn, a subagent still running after the main turn, and the handed-over
child exiting.

* refactor(mobile): the chat reads the main agent's working state through the shared rule

Behaviour is unchanged: the same two terms, now from the one function the host projection and the
desktop chat read.

* fix(codex): a Stop naming no turn never interrupts an earlier turn

It fell back to the id an earlier turn/start answered with when the latest start went unanswered,
or when the journal showed a compaction Codex had not started, and reported that as stopped.

* fix(native-chat): a Stop naming no turn never says a turn had already finished

When the provider found nothing left to stop, for instance a turn that ended between the host's
check and the interrupt, the chat got "The provider had already finished this turn." for a turn
the Stop never named. It now ends quietly, as a Stop with nothing in flight does.

* fix(native-chat): one Stop the host could not settle no longer refuses every later one

A Stop naming no turn has one operation key per session. When the host could not settle one, it
answered every later Stop under the same id as unknown until the id expired. Once the host says
so, the next press is a new Stop; transport doubt still replays the same id.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* test(native-chat): read Stop operation ids without a cast

* fix(native-chat): a Stop whose answer was lost no longer swallows the next one

A Stop that names no turn has one operation key per chat. When its answer was lost in transit, the
chat kept the id, so every later Stop replayed it; the host answers a replay as already handled, so
for up to a day Stop stopped nothing. The id is now dropped once the call settles, however it
settles. A second press while the first is still on its way still shares its id.

* refactor(native-chat): a Stop naming no target keeps its operation id only for its own call

The chat kept each write's operation id per payload across calls, and dropped it only on some
settle paths. That is right for a write naming what it acts on, but a Stop naming no turn, and a
stop of every background task, share one payload with every later one, so any path that kept the id
made the next Stop replay as already handled and stop nothing. One path was still open: an answer
that arrived after the chat moved to a new fence.

Whether a write names its target is now decided once, before its id is picked. One that names none
keeps its id only while its call is in flight, so a press made meanwhile joins it, and releases it
when the call settles, however it settles. The release runs only while the key still holds that
call's id, so a joined call settling late cannot drop a newer one's. This replaces the per-path
exceptions for a thrown call.

* test(native-chat): read the Stop fences without a cast

* test(native-chat): pin the new id for a named cancel the host could not settle

After the Stop naming no turn moved to a per-call id, the only test of the unknown-refusal release
was gone, and the half that stays, for a cancel naming its turn, could be removed with every test
green.

* fix(native-chat): a Stop pressed after a new message stops it, even while the last Stop is unanswered

A Stop naming no turn shared its operation id with any press made while it was still in flight. The
host runs a chat's writes in order, so a message sent between two presses was accepted after the
first Stop ran, and the second press replayed that Stop as already handled and left the message
running, although the chat had already withdrawn it from the outbox.

A write naming no target now gets a new id on every press and is never kept, so each Stop acts on
whatever is running when the host reaches it. A write naming its target keeps its id exactly as
before. A double press can ask the provider to stop the same turn twice, which it tolerates.

* fix(native-chat): Stop no longer blinks off as Claude opens the turn for a message

Claude's echo of a sent message both answers the send and opens its turn. The echo settled the send
first, so the host published the message as answered one frame before the turn it opened, and for
that frame the chat read nothing running: Stop turned back into Send, and Working blinked off in
every session list, for tens of milliseconds on each turn.

The echo now settles the send after the turn it opens has been emitted, so the running turn is
published first.

* fix(native-chat): a message a Stop withdrew comes back to its sender's composer

A Stop withdraws every message the host holds but has not run, and S also
drops the ones this client had not handed over yet. Either way the message
left the chat and its text survived only in a hidden journal row and the
in-memory ArrowUp history.

The sending client now puts the withdrawn text and images back in that
pane's composer, after whatever is typed there. Withdrawn is read from the
rejection reason through one shared check, which the outbox reconcile now
uses too. The composer is written before the entry leaves storage, so a
failure between the two repeats the text instead of losing it, and an entry
storage no longer holds is never given back again, so a replay, a second
view or a remount restores it once. Only this client's outbox holds the
entry, so other viewers still see the message disappear. A failed Stop
withdraws nothing on the host and gives nothing back.

* fix(native-chat): withdrawn text put back during an IME composition is not lost

While the IME owns the field, the composer ignores a programmatic draft, and
the next composed keystroke wrote the draft without the restored text, after
its outbox entry had already been dropped. The composer now holds text
appended mid-composition, keeps it in the cache after each composed write,
and shows it once the composition settles, the way attachments that land
mid-composition already wait for it.

* test(native-chat): pin that only a withdrawn message comes back to the composer

* test(native-chat): set up the composer's window API for every describe in the composition-race file

* docs(native-chat): note that the withdrawn check reads the legacy reason until a typed category lands

* test(native-chat): pin that text put back mid-composition shows once, even beside a mid-composition clear

* fix(native-chat): land a late settlement from a streamed turn's end after that turn's rows

A settlement that says a streamed turn ended waits for the session's event
sink to drain before writing its dispatch row. The journal reducer still
refuses to overwrite an accepted or rejected send.

* fix(codex): settle a send from the end of the turn Codex answered it into

The turn/start answer names the turn that holds a send. The send's echo
entry now keeps that binding, in memory only. If the bound turn is
interrupted without echoing the send, the send is withdrawn: Codex clears a
turn's pending input on interrupt, so the model never saw it. If the turn
fails first, the send is rejected in Codex's words. A completed turn settles
nothing, since Codex records pending input when it finishes and the echo is
still due. An answer read after its turn already ended is settled by that
end. The echo is still the acceptance and carries the item key.

* test(codex): a send settles from the end of the turn Codex answered it into

The fake Codex keeps 0.157's turn bookkeeping, and can deliver the turn/start
answer after turn/started or after turn/completed. The tests cover:
- a Stop before any echo withdraws the send, and the working rule reads idle;
- a steered follow-up is withdrawn when the turn is interrupted;
- a failed turn rejects the send in Codex's words;
- a completed turn leaves the send to its echo;
- a normal echo and a late echo;
- two steered sends in one turn;
- an answer read after the turn ended;
- a timed-out answer;
- child-thread turns;
- how a binding dies.

* refactor(native-chat): drop the stream flush before a late turn-end settlement

Nothing reads the order of a dispatch row against the turn's terminal row:
the reducer keeps a settled send terminal and the working state is derived
from both. The echo acceptance on the same path never waited either, and the
wait could drop the settlement on a failed sink barrier.

* fix(codex): settle a failed turn's sends at its end, not at its error

Codex keeps a failed turn's pending input and records it after the error
frame, before turn/completed. Settling at the error rejected a steered
follow-up the model had in fact received, so a Retry would send it twice.

* docs(codex): say a completed turn echoes what it took before it ends

Codex records a completed turn's pending input before `turn/completed`, so
a bound send that turn never echoed is left for recovery, not awaiting an
echo. The comments and one test title said the echo was still due.

* test(codex): settle a send whose answer is read after its turn failed or completed

A failed turn that ended before the answer rejects the send in Codex's words,
once; a completed one leaves it admitted and still armed for its echo.

* refactor(codex): read a failed turn's reason with the typed thread-fact reader

* fix(native-chat): a Stop that names no turn and ends nothing says why

The host sends a Stop naming no turn to the agent only while the chat reads
working. When the agent ended nothing, the Stop wrote no row, so it looked
ignored. It now writes one: Stop could not reach the agent, in the agent's
own words when it refused the interrupt.

* fix(codex): hold a cold send until Codex opens its turn, and stop the turn it opened

Codex answers turn/start before it opens the turn, and refuses an interrupt
until then. A Stop queued behind a cold send ran in that gap, named the
answered turn, and was refused. The send's handover now lasts until Codex
opens that turn, or provably will not: the turn ended, the primary thread
stopped running, or the child ended, bounded by the turn/start deadline.
A steered send, whose turn is already open, does not wait.

A Stop naming no turn now interrupts the turn the journal shows, else the
primary-thread turn Codex reported started and not yet ended. The per-start
answered id is gone: it was never cleared at a turn's end.

* fix(native-chat): give back a send already on its way only when the host withdraws it

Stop took the in-flight send out of the outbox and put its text back in the
composer at once. The send still landed ahead of the Stop, so the chat read
working for a moment before the host withdrew it, and a send the agent had
already taken came back as well. The in-flight send now stays until the host
answers it, and the withdrawn-message restore gives it back from that answer.

* refactor(native-chat): read a Stop's withdrawal through the rejection classifier

dispatchWasWithdrawn matched the legacy reason string. It now asks the
classifier, which reads the typed fact first and keeps that string only as its
own fallback, so a withdrawal written as a fact with a sentence is still given
back to the composer.

* fix(native-chat): a Stop Codex took but Orca could not confirm is not reported as reaching nothing

When Codex acknowledged the interrupt but Orca could not verify the turn's
processes ended, a Stop naming no turn wrote "it had no turn running to stop",
though the turn then ended as interrupted. The adapter now says the Stop was
taken but unconfirmed, and the row says Cancellation was not confirmed.

* fix(codex): a held cold send never delays closing the chat or quitting

A cold send's handover waits for Codex to open its turn, and that wait sat
in the session queue ahead of the close and quit eviction, so either could
wait out the 30 s request deadline. The host now releases those waits before
it queues a close or starts quit teardown, and the adapter releases them when
it is asked to close the child and on every exit, including one whose end
publication is backpressured.

* fix(native-chat): a refused Stop says the agent declined, and names it

"Stop could not reach the agent" was wrong: the agent was reached and
declined. The row now reads "Codex had no turn running to stop." or
"Codex didn't stop: <Codex's words>.", naming the chat's agent.

* fix(codex): a Stop waits for the turn Codex answered to open; the send no longer does

Codex answers turn/start before it opens the turn and refuses turn/interrupt
until then, so a Stop naming no turn in that window was lost. The send's
handover used to wait for the turn to open, and a close or quit needed its own
release to get past that wait.

Now only the Stop waits. A Stop naming no turn, finding no journal turn and no
open one, reads the turn Codex answered the latest pending send into and has
neither opened nor ended, and waits for it: bounded at 5 s, under the quit
eviction budget, and ended by that turn opening or ending, the thread going
idle or failing, or the child exiting. If the turn opened it is stopped;
otherwise the Stop reports that Codex had no turn running. The send returns at
Codex's answer, so a close or quit with no Stop pending is never delayed, and
the release plumbing through the adapter, router, close and quit is gone.

* fix(codex): the Stop's wait reads a stopped thread from the thread-facts reader main kept

Brennan Benson 2dc2693953 fix(native-chat): a turn a proven crash cut short reads interrupted (#23456)
* fix(native-chat): a turn a proven crash cut short reads interrupted, ending when it was last seen working

* fix(native-chat): end a probe-proven turn at the last row the journal wrote live

A revised item keeps its first sighting's timestamp, so a long command or a streamed reply read as ending when it started. The reducer now tracks the latest live row the same way it tracks all activity.

* test(native-chat): give the unexpected-exit fake journal its live-activity read

* refactor(native-chat): read the journal's live bound only for a probe-proven death

* fix(native-chat): mark what a journal open settles for a gone host as crash reconciliation

A crashed host's working roster is retired when the journal reopens. That row was
written live, so a probe-proven turn ended at the relaunch and counted the downtime.

* fix(native-chat): bound a probe-proven death with the last time Orca proved the owner alive

A crash mid-tool left the turn ending at the tool call's start, because Claude writes nothing
while a Bash call runs. The death evidence now records the lease's last renewal before the
death as lastProvenAliveAt, and the turn ends at the later of that and the last live row,
capped at the probe.

Parking a lease in recovery no longer stamps lastRenewedAt, since nothing proved the owner
alive then; a child that outlived Orca would otherwise have its turn count the downtime.

* test(native-chat): a failed acquisition parked in recovery keeps its last proof of life, and the timing read goes through the display selector

* refactor(native-chat): move the submission dispatch folds out of the journal reducer

Main grew the reducer to its line limit, so the live-activity bound tipped it over. The dispatch
row and echo-acceptance folds move unchanged into their own module.

* test(native-chat): a send or reader that opens a crashed chat settles a proven death interrupted

Main's open-time settle test still asserted the old rule, where only a watched exit proved a death.

* docs(native-chat): say which proofs of death record a last proof of life

* fix(native-chat): a proof of life bounds only the owner that wrote the turn

A start after a crash that spawned a child and then failed without proving it gone parks that
child for recovery; when recovery finds it gone, the proof of death carries its proof of life,
which is after the crash. The older turn then ended there and counted the downtime.

The journal now derives the fence of its newest live writer, and the lease that holds the proof
names the owner it released by the fence it moved to. The last renewal counts only when that
move was one step past the writer of the turn.

* test(native-chat): a crash with a send in doubt still ends at the last proof of life

The reopen settles that send at the new fence, so the owner check must read the fence of live rows only.

* fix(native-chat): a proof of death judges only the turn its own owner wrote

The settle read the record's latest proof of death for whatever turn a gone generation left
running. After a crash, a start that reserved a new fence cleared the relaunch's proof, and if
it then failed, its own child's death (a watched exit at the failure, or a probe finding the
child it left for recovery gone) ended the older turn an hour after the crash.

Every proof of death now records ownerFence, the fence of the owner or reservation it is about;
a fence names exactly one owner. The journal derives the fence each item was created at, and a
running turn is interrupted only by a proof naming its own owner; otherwise it is unverifiable.
Evidence older builds wrote keeps their rule. This replaces the derived one-step fence check.

* test(native-chat): every writer of a watched exit names the owner it released

A watched exit that names no owner reads the older rule, so the settle alone cannot tell a
dropped field; the writers are pinned directly, including past a recovery floor.

* test(native-chat): give the fake journal's cast its safety rationale

* fix(native-chat): a proof of death written after a chat opened revises the turn it left unverifiable

On desktop the chat on screen at relaunch opens before the startup reconcile has probed its owner,
so the open settles the cut-off turn unverifiable. When the reconcile then records the proof, it
re-runs the same settle for every open conversation, which revises that owner's unverifiable turns
to interrupted with the proof's end. Any later open re-runs it too, so a failed write converges.
Only upward, only for a proof that names the turn's own owner.

* test(native-chat): a chat read before the reconcile reads unverifiable, then interrupted

Covers the reconcile revising an open chat to the last renewal (27 s) and a subscriber being sent
both states, a start after the crash whose running turn the queued revision leaves alone, a failed
revision write converging at the next open, a proof about another owner or from an older build
never revising, and a second settle writing nothing.

* fix(native-chat): revise an open chat's turn wherever a proof of death is written

The store tells its listeners, once committed, of each record a transaction gave a new proof of
death, so every writer (the startup reconcile, a recovery that stopped a child which outlived
Orca, a failed start, a watched exit) triggers the same serialized resettle for a chat already
open. The reconcile's own callback is gone. Quit stops listening first, and a queued resettle is
drained with the starts.

* test(native-chat): a failed exit settlement is retried in place once the exit is recorded

Recording a watched exit now queues the same settle an open runs, so the turn converges without
waiting for the chat to be reopened. The reopen and read-after-restart cases now refuse that retry
too, so they still pin the open's own settle.

* test(native-chat): tests that pin a send settling a failed exit refuse the in-place retry too

The exit's release now queues the same settle, so two tests named for the send's settle refuse that
retry as well; the comments that said nothing retries it now say what does.

* fix(native-chat): name the explanation row by the death it explains, so a retried settle adds no second row

* fix(native-chat): end a crashed turn at its owner's provider output, never at a later send

A send accepted into a crashed chat before the proof of death wrote a submission row live, and the journal-wide last-live-row bound counted it, so the revised turn ended at the send and counted Orca's downtime. The bound is now the last row the owner's provider child wrote, per writer fence: submissions, dispatch rows and crash reconciliation are Orca's or the user's, and a newer owner's work says nothing about the dead one.

* fix(native-chat): end a crashed turn at its last proof of life, never at a timeline row

The end of a probe-proven death was the later of the last renewal and the last live timeline row. A send accepted into a crashed chat before the proof writes a row live, so the revised turn ended at the send and counted Orca's downtime. Rows cannot tell the agent's output from Orca's or the user's, so the end is now the last renewal alone, never after the probe, and never before the turn began. The journal's live-activity bound and the reopen's recovered marker, which existed only for it, are gone.

* feat(usage): show ZCode Coding Plan quota on current main (#23520)

Shows the ZCode Coding Plan quota in the status bar alongside the Claude and Codex usage readouts, reading the key from the user's own ZCode config.

Credentials are scoped tightly: the host must be an exact match in the allowlist, HTTPS on port 443 only, `redirect: 'error'`, and the key is checked for CR/LF before it reaches a header. The key itself is never stored or logged — account identity is an HMAC.

Both JSON inputs (a user-edited config file and the remote quota response) are narrowed at runtime rather than asserted, and the request cancels an unread response body on the error path so it cannot trip the undici parser crash (orca#8695).

* fix(mobile): paired clients re-derive a kept terminal after a cold restore (#23109)

* fix(mobile): paired clients re-derive a kept terminal after a cold restore

A renderer frame published before a cold-restored terminal's PTY registered
was fenced to an empty tab list and recorded as accepted, and the renderer
never resends unchanged content. When registerPty binds a surface the
accepted frame fenced out, re-merge that frame so the fence reads current
state.

* test(mobile): drive the live desktop window through the runtime's desktop seam

* test(mobile): the re-derive path never flushes the store synchronously

* test(mobile): a re-derived frame must not bring back a surface the host retired after accept

* fix(mobile): a re-derived frame changes membership only for the registering surface

The replay re-ran the whole accepted frame, so a surface the host retired
after accept (a phone close whose remote PTY is still exiting, or a closed
chat tab) came back. Every other surface now keeps the host's current
decision; the removal repair is extracted from the terminal retirement
helper so non-terminal tabs are removed the same way.

* test(mobile): a re-derived frame must not drop or disown a phone-created terminal the desktop has not published

* fix(mobile): a re-derived frame does not infer renderer retirements from its older frame

* revert(mobile): drop the replay of a fenced renderer frame

Reverts the production parts of a88e1eaa0a, f5b99d0003 and 5af1c6d97a: the kept
renderer frame, rederiveFencedRendererSurface and its registerPty call, and the
mergeRendererMobileSnapshot / removeMobileSessionSnapshotTabs extractions. The
fence will instead read the host's saved membership record. The test file stays
and is rewritten for that mechanism.

* fix(mobile): the paired-list fence admits a terminal the saved session still lists

After a cold restore the in-memory mobile snapshot and PTY table start empty,
so in a repo with host-authoritative terminal membership the fence dropped a
restored terminal whose renderer frame arrived before its PTY registered, and
paired clients never listed it. The fence now also admits a surface the host's
saved workspace session still lists (tab under the worktree, leaf in its
layout), and registerPty pushes the listing so pending-handle turns ready at
once. A restored pane whose PTY never returns is listed as pending-handle, as in
repos that are not host-authoritative.

* test(mobile): keep the desktop window stub's type assertion on its SAFETY line

* fix(mobile): coalesce the registration push for a listed restored terminal

registerPty pushed the paired list immediately on every registration that backs a
listed surface. The desktop's graph sync after a spawn already publishes the same
pending-handle to ready flip on the 50 ms coalescing window, so each restored pane
cost two pushes, and a restore of N panes cost N immediate full-list pushes per
client. The touch now rides the same coalescing window, which still covers a
registration no graph change follows.

The test's "unchanged" sync dropped the graph's tab, which is itself a change, and
its no-extra-push assertion ran before any coalesced push could fire; both are
fixed, and a restore of two panes is asserted to push once.

The fence comment no longer claims the new clause keeps pending leaves out of the
graph: once the surface is listed, its leaves pass the shared predicate through
that listing, as any listed surface's do.

* fix(mobile): read saved membership only from the worktree's own session partition

For a runtime-host workspace, emptying the owning partition re-routes session reads to a single
other partition that still lists the worktree. If that older copy lists a surface a retirement just
removed, a lagging renderer frame could re-admit it. The saved-membership check now reads only the
partition the worktree's host names, so it never trusts a fallback copy.

* test(mobile): pin the own saved partition for every workspace host kind

Also correct the immediate-emit comment: only an exit bypasses the window; a registration's ready flip coalesces.

* fix(mobile): size a terminal's first subscribe from the document's reported cell box (#23080)

* fix(mobile): size a terminal's first subscribe from the document's reported cell box

#22960 sent phone dims on a terminal's first subscribe by opening a throwaway
empty terminal (init 80x24 ""), awaiting its ready and measuring, behind a
per-document first-subscribe mark whose lifetime was tied to web-ready. That
cost a second xterm/WebGL instance and ~150 ms per open, plus lifecycle state.

The document now measures the cell box without a terminal (xterm 6's
CharSizeService strategy, rounded as the renderer rounds it) for every
text-size preset and reports it with its viewport in web-ready; a table,
because the text scale only reaches the document after that notify. Each
init's ready reports the box xterm actually laid out, which replaces the
probe's entry. The controller answers fitDimensions/measureFitDimensions from
that table and the view's layout with no message; without a table it asks the
document as before.

The session seeds an unmeasured viewport synchronously in subscribeToTerminal,
so the first subscribe carries dims by construction. Deleted: the empty init,
its awaitReady gate, deferFirstSubscribeUntilViewportMeasured and the
subscribedDocuments mark. The fit pass is unchanged and still covers a
document that reports no cell box.

* refactor(mobile): read the reported cell box through in-narrowing, not Reflect.get

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): correct the probe's cell-box guess from the box xterm lays out

The web-ready probe is a guess: building the WebGL addon creates no context,
so a context that fails on load lands on the DOM renderer, whose width is not
snapped and depends on the column count. Before, a ready box that differed was
only logged; the first subscribe had carried the wrong column count, the host
echoed it, the fit pass saw the viewport equal to the host's dims, and the grid
stayed slightly shrunk. The store also kept the WebGL width after a context loss.

The document now reports the box xterm laid out whenever it changes (from
onRender, which covers a renderer swap and a DPR change that
onDimensionsChange does not fire for, and at ready). The store replaces the
guess; when that changes the current text size's entry, the view calls
onCellBoxChange with xterm's grid and the session re-fits, running the bounded
fit pass if the dims moved (one resubscribe). Equal boxes do nothing.

The RN layout box now survives a document reload; the document's own viewport
only stands in until the view reports a layout (on the page, web-ready arrives
first). The mismatch console.log is gone, and the probe's rounding names the
xterm version it copies.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): correct each cell-box guess at most once, so a DOM renderer cannot loop

On the DOM renderer the cell width is the rounded canvas width divided by the
column count, so every re-init at new cols reported a new box. Each one counted
as a correction, a floor over floats could flip the fit between two sizes, and
each flip landed converged, which reset the resubscribe budget: an unbounded
series of full-snapshot resubscribes.

Only the first laid-out box for a guessed text size may be a correction; later
reports still update the store, so fits stay truthful, but never resubscribe on
their own. The fit's floor gains a 1e-6 epsilon so floating-point error at an
exact boundary cannot flip a column or row. New document tests pin the render
report after a renderer swap and the report at ready for a paused renderer.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): make xterm the only terminal cell measurer

The document builds its real terminal before web-ready, at the app's
text scale, and reports the box xterm laid out; the first init reuses
that terminal. The page-side prediction, the per-scale guess table and
the once-per-document correction are gone. The app remembers the box
per text scale for its lifetime, so a later open at a known scale
subscribes with phone dims at once. A box that changes at the same grid
(renderer swap, pixel ratio) refits the open terminal in place.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): keep commands queued before the terminal WebView first loads

A subscribe sized from the stored cell box can queue init before the
native WebView reports its first load start, which cleared the queue
and left the terminal blank. Only a reload now drops queued commands.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): re-init a document that lacks the subscription's init, and fit one frame width

- Web-ready now says whether the document holds the terminal's latest init
  (a reload before the first ready drops a queued one); the session
  resubscribes any initialized terminal whose document lacks it.
- One grid fit, shared by the app and the document, fed the unrounded frame
  width React Native laid out; it keeps exact fits whole at fractional pixel
  ratios. The document's viewport-width fits are gone.
- The page builds every document at the scale the view mounted with, as the
  native WebView does.
- A new document's first cell box is compared against the grid the
  subscribe fitted from the stored box.
- The terminal built before ready stays hidden until its first init.
- The cell-box census matches glyph-measurement techniques, not names;
  the store's unused clear() is gone.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): build the terminal before ready only for the view shown at mount

A session mounts one terminal view per tab, and each built xterm and a
WebGL context before ready: 20 tabs made 20 contexts at load, past the
~16 a page (or Android's shared WebView renderer) holds, and native logged
32 context losses. Only the view shown when it mounts builds early now;
the rest build at their first init as before. Deferring the WebGL addon
instead would change the reported box: the DOM renderer lays out 7.8x15
where WebGL lays out 7.667x15 at the same font.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): write a WebView document's start values into its page, not an injected script

Android ran the pre-content injected script after the document's own in
1 of 22 documents on the emulator; that document started with no text
scale or shown flag and built a terminal it should not have. The values
now sit in the page ahead of the document script, one source object per
start pair so a render never reloads the WebView.

* test(mobile): the pre-ready terminal measures and reports while hidden

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): measure only the laid-out frame, and refit on a new grid, not a new width

- A measure needs both of the frame's dimensions from React Native; the
  document's viewport-height fallback is gone, and before the first layout
  the handle answers no fit without asking the document.
- A frame width change that still fits the PTY's grid from the stored box is
  a no-op, so sub-pixel layout jitter no longer re-measures. The width ref is
  written in that effect rather than during render (react-doctor).
- One "last grid" ref: the last reported grid, or the one a subscribe fitted
  from the stored box.
- The page render rig measures through the frame it laid out, as the session
  does, and lets the replay's fit settle before its resize-refit witness.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): let only the current terminal document's ready flush

A reload kept the WebView and its onMessage, so the old document's late
web-ready flushed the queue into the reloading view and the new document
got a second init. Each document now gets its own view (keyed on a
generation the controller owns), every notify carries the generation of
the view that received it, and a web-ready from a replaced document
flushes nothing and stamps nothing.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): drop every notify from a replaced terminal document

One rule at the receive boundary: a notify from any generation but the
current one is dropped, whatever its type, not only web-ready.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): make fitDimensions a pure question; name each generation counter

- fitDimensions no longer records the grid. A width change to a new grid
  asked it first, so the DOM renderer's report of that grid's box read as
  "same grid, new box" and refit again. Only the first-subscribe seed
  (seedFitDimensions) records the grid the document's first report is
  checked against.
- viewGeneration counts the views, readyGeneration counts web-readies.
- replaceDocument no longer resets the load flag; the load-start reset
  stays as the guard for a view that reloads itself.
- The name-based lifecycle census is replaced by a behavioural test.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): typecheck the handle mocks, drop the unused cell-box get

- The two handle mocks carry both fitDimensions and seedFitDimensions,
  and the fake-timer acts return nothing, so the three test files check
  under tsconfig.test.json again.
- terminalCellBoxes.get had no product caller; the store's tests assert
  through fit.
- The load-start comment says what the controller does now.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): hold the grid the document has, ignore a replaced view's load start, dispose a failed pre-ready terminal

- The document reports a new grid even with an unchanged box, so an
  in-place reflow on WebGL is held before a later renderer swap at that
  grid; the swap then refits. The app's apply paths do not hold the grid
  themselves: the DOM renderer's box follows cols, and a grid held on
  apply would read its own box as a renderer change and loop. One
  writer (holdGrid) holds the seeded or reported grid.
- A load start from a view a replacement unmounted is ignored, as its
  notifies already are.
- A terminal whose open throws before ready is disposed, not only
  unreferenced.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): ignore every native event from a replaced terminal view

One wrapper binds each WebView lifecycle event (load start, error, HTTP
error, render process gone, content process terminated) to the view's
generation, so a replaced view's late event cannot reset, replace or
put an error over the current document.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* test(mobile): a DOM seed refits once on its first report, not on the refit's own

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): subscribe a terminal only after its document is ready

The document still builds its terminal before ready and reports the cell
box xterm laid out in web-ready; the app now subscribes after that ready
and fits from that box, so nothing is sent to a document before it is
ready. Everything that made a pre-ready subscribe safe goes: the
app-lifetime box store, the seed fit, the per-document view generations
and their event filtering, the init tracker and the hasInit resubscribe.
The native view reloads in place again and web-ready keeps main's reload
rule. Boxes are kept per view; the grid a document last reported still
guards the in-place refit against the DOM renderer's cols-dependent box.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): hold one reported cell box and the grid the subscribe fitted

The controller keeps only the box the current document last reported,
not a per-text-size store: the document re-reports on a scale change.
The subscribe after ready fits from that box and holds the grid it
fitted, so the DOM renderer's first report at that grid (a new box)
refits once in place and converges; refit and apply paths hold nothing.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): fit only a ready box at the app's scale; forget a reloaded document's box and grid

A reload keeps the document's mount scale, so a ready after a text-size
change reports a box at the old scale; that box no longer sizes the first
subscribe, which then takes the no-box path. A readiness reset drops the
old document's box and held grid, so the new document's first DOM report
at the same grid does not refit.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): give the terminal document its frame at init, and fit text scale over it only

A subscribe sized from the ready box sends no measure, so the document
had no frame when the text size changed and reported the pre-refit row
pitch. The app's init now carries the frame it laid out, in the fields a
measure uses; the router takes it from either. The text-scale fit reads
only that frame, with no viewport fallback.

* docs(mobile): say why a frameless text-scale change skips the resize

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): one cell box per terminal notify, not an array

web-ready and cell-metrics carry `cellBox: {fontScale, cellWidth,
cellHeight} | null`; the document's `laidOutCellBox` returns one or
null and the parser validates one object. The text-scale match moves
from web-ready into `handle.fitDimensions`, the one place a box is fitted.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): fit terminals in the app from the reported box; drop the measure round trip

The app already holds the box the document reported, so the refit and
the fit pass await the init's ready and call `handle.fitDimensions`
instead of posting `measure` and waiting on `measure-result`. The
document's measure, its retries, and the measure promise and timeout go.
The document still resizes locally on a text-size change, so every grid
the app sends (init, resize, reflow) carries the laid-out frame it was
fitted to. `holdSubscribedGrid` replaces `subscribeFitDimensions`, so
the only fits are `fitDimensionsFromCell` and `handle.fitDimensions`.
The render rig reads its fit from the ready box. The recorder adapter
mounts the new handle with the same recorded effects; the goldens it
mounts move on their adapterSha256 header only.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): keep the terminal frame in one ref, and notify a new width imperatively

The session held the frame in a height ref, a width ref, a width state
and the refit's own width ref. It now holds one `terminalFrameRef`
({width, height} | null until the first layout; a hidden 0x0 layout
keeps the last box). onLayout notifies a new width imperatively, as it
does height, and the refit's notify skips a width whose fit is the grid
the PTY has. `terminal-frame-width-refit.ts`, the width state and its
effect go. The subscribe's layout gate reads "no frame yet" directly.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): subscribe a held-back terminal on the frame's first layout only

`handleTerminalFrameLayout` ran on every onLayout; it now runs once, when
the frame first has a size. Later layouts only notify a new width.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): size the first subscribe inline in subscribeToTerminal

`sizeTerminalViewportFromCellBox` wrapped five lines in a 37-line
module; the subscribe now fits the ready box against the frame, holds
that grid and records the diagnostic itself. The helper's tests fold
into the subscription tests, which move to the subscription's name.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): drop the unreachable font-size guard on the reported cell box

xterm 6.1.0-beta.303 updates the render service's cell box in the same
task that sets `options.fontSize`: CharSizeService.measure fires
onCharSizeChange, and RenderService.handleCharSizeChanged runs the
renderer's `_updateDimensions` (DomRenderer.ts:359, WebglRenderer.ts:229).
`term.onRender` fires from RenderService._renderRows after the rows
are drawn (RenderService.ts:213, CoreBrowserTerminal.ts:538), and the
document writes its text scale and the font size in one task
(text-scaling.ts applyTextScale, terminal-init.ts init). So no report
can read a box between the font and the scale; the guard and its test
go. A new test pins the real order: no report when the font is set,
the new box at the new scale on the next render.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): one start seam, no source cache, the reported box as an object

- `useState` already pins each view's WebView source at mount (a new
  test re-renders at another text scale and gets the same object), so
  the module-level `webViewSources` Map goes.
- `initialTextScale` and `buildsTerminalBeforeReady` become one
  `start(): { textScale, shown }` seam.
- `reportedCellBox` holds the last reported box and grid, not a string key.

* test(mobile): repin the RPC recordings to this branch and re-record

The terminal refit now fits in the app from the reported box and reads

keeping its recorded effects. `baseline` is repinned to 21954dbd2f, the

* refactor(mobile): hold the reported cell box and its grid in one ref

The controller kept the box in `cellBoxRef`, the grid in a string
`lastGridRef` and wrote it through `terminal-held-grid.ts`. One
`heldRef` now holds `{ cellBox, grid }`, as the document's own
`reportedCellBox` does: web-ready writes the box, every cell-metrics
report writes both, `holdSubscribedGrid` writes the grid, and a
readiness reset clears it. Same write points, so the one-refit bound
holds; the DOM-loop and refit-once tests pass unchanged.

* refactor(mobile): the terminal document holds the grid and decides each refit

The document already kept the last reported box and grid; the app kept
a mirror of both to decide the refit. Now the document decides: its
`cell-box` notify carries `{ cellBox, refit }`, sent only when the box
changes, with `refit` a box that changed at a kept grid. web-ready
records the pre-ready terminal's box at its 80x24 grid, and the first
init that reuses that terminal holds the init's grid, so the DOM
renderer's first report refits once, as the subscribe's hold did. A
re-init no longer clears the record, so a new renderer at the same grid
still refits. The app keeps one `cellBoxRef` and `holdSubscribedGrid`,
`heldRef` and the grid on the notify go. The one-refit, DOM-loop and
renderer-swap tests move to the document with the same scenarios.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): one init options object, and a frame on every grid

`init` takes `{ cols, rows, data, preserveScroll, oscLinks, frame }`
instead of six positionals, and `init`, `resize` and `reflow` (handle

check reads `!dims` alone, and the controller's test file is named for
the `cell-box` notify it now covers.

The frame's onLayout made four calls and held the classification

height, subscribes the document held back for the first layout, and
notifies a later width change. `handleTerminalFrameLayout` is named for
what it does: `subscribeIntendedActiveTerminal`. The layout tests move
to that hook.

Surfaces ZCode CLI session history in AI Vault, so past ZCode sessions show up next to the other agents' instead of being invisible.

ZCode stores sessions in the same SQLite shape OpenCode uses, so this reuses the existing OpenCode lister and parser rather than adding a second scanner — the worker only varies the agent it stamps on each row. Discovery covers the native home and any WSL homes.

SQLite rows are narrowed at runtime rather than asserted: the statement API returns untyped column values, so the declared row shape is only a claim until something checks it, and a drifted schema or a database written by another tool reaches the same code.

* perf(ci): diff against the merge commit's first parent so PR checkouts can be shallow (#23562)

Every changed-path gate asked git for `--merge-base "$BASE_SHA" "$HEAD_SHA"`,
which needs the event payload's base SHA to be in the local graph. That is the
only reason two jobs cloned all 8127 refs' history. On a pull_request checkout
HEAD is already the merge commit, so its first parent is the base side and no
merge base has to be computed. config/scripts/git-pull-request-diff-base.mjs
resolved that for the two Node gates; the workflow's inline gates now use the
same helper through a small CLI rather than open-coding it.

code_paths gates all 22 jobs, so its checkout is charged to the start of every
one of them: measured 20.7s to 1.6s, keeping blob:none because its sparse tree
is ~7 files and leaves no blobs to refetch. Static analysis drops the filter
instead, since populating all 30,226 files makes blob:none force a second
promisor fetch: 23s to ~11s.

Verified on a real merge ref. At depth 50 the old and new forms produce
identical changed-file sets. At depth 2 the new form still works and the old one
fails with `fatal: bad object`, which is the failure a stale base would have
caused once the checkout stopped being complete.

Also drops the dead resolveBase + merge-base prelude in the changed-code gate,
whose result resolvePullRequestDiffBase already discarded on every PR.

* feat(mobile): the keyboard covers the page like a native screen, and the shell says its height (#23110)

The shell no longer shortens the WebView for the keyboard; it publishes the keyboard height like the safe-area insets, so native's keyboard lift, refit hold and dismiss key run on the page unchanged. Keyboard and inset arithmetic read the shell's OS through a host-os seam. One page-version floor (manifest pageVersion, shell floor 1) replaces per-feature accept negotiation; a page below the floor gets the existing update wall, a desktop with no bundle keeps native screens. iOS shell drops the form accessory bar and its own keyboard observers. Native session screens untouched.

* fix(agent-session): wait for in-flight session-store writes before teardown returns (#23545)

* fix(agent-session): stop lease renewal before the renewal's write lands

Clearing the renewal interval only cancelled the next tick. A tick already
past its guard still had a whole-file store transaction to commit, and the
store's transaction lock re-creates the store directory before it writes, so
that commit could land after host teardown had finished releasing everything
it touches.

`stop()` now resolves once the tick in flight has finished writing, and host
teardown's stop-lease-renewal phase waits for it. The three test harnesses
that model a host vanishing without a clean quit shared a copy of the same
incomplete shutdown; they now share one helper that waits.

The symptom was a CI flake: the refusal-oracle spec removes its temp
directory in `afterEach`, and a renewal landing mid-removal put the store
directory back, so the removal failed with ENOTEMPTY on the temp root.

* fix(agent-session): wait for the delivery loop's restart when abandoning a host

The abandon helper disposed the delivery loop and moved on. Disposing only
stops the loop's NEXT step: a step already past that check keeps going, and
the restart it runs for an accepted send reserves an owner, which is a store
commit. The store re-creates its own directory before every commit, so that
commit put the directory back under the temp-directory removal the test does
next, and the removal failed with ENOTEMPTY.

Quit already waits for exactly this work, in its drain-attaches phase — every
attach is registered with the task queue from enqueue. The helper now runs
the same drain, in quit's order, so it waits for both producers that reach
the store after the last awaited call returns.

Adds a regression test that holds the loop's restart inside its provider
acquisition and asserts abandoning does not return until it lands.

* chore: re-trigger PR checks

The push to 2ecc9c6e emitted no pull_request event, so the matrix never ran.

* fix(sidebar): clip worktree card content to its border (#23566)

* fix(runtime): answer terminal.subscribe at once for a pane the desktop already has mounted (#23512)

* fix(runtime): answer terminal.subscribe at once for a pane the desktop already has mounted

A mobile subscribe to a PTY with no headless model asked the renderer to
mount its tab and waited for a newer serializer settle. The renderer drops
mount requests for tabs it already has mounted, so a reattached daemon PTY
whose restored provider snapshot outranked the live renderer held the reply
for the full 3 s deadline. A live renderer screen now proves attachment and
is adopted directly; an unmounted pane still requests the mount and waits.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(runtime): treat any renderer answer, even a blank screen, as an attached pane

A fresh shell that has printed nothing has a registered serializer and an
empty screen; requiring non-empty data sent it back through the dropped
mount request and the 3 s wait. A blank screen skips the wait but does not
replace the chosen snapshot, so a parked pane cannot erase provider history.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(runtime): treat a mounted pane with unsettled output as attached

The stable renderer snapshot returned null both when no renderer answered
and when output advanced under every retry, so a desktop pane printing
continuously still took the dropped mount request and the 3 s wait. It now
returns a typed outcome (settled, moving, absent); moving skips the mount
and publishes the chosen snapshot, and late recovery still requires settled.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(runtime): adopt only a renderer-ordered screen when probing a mounted pane

The attachment probe read the terminal before knowing it would adopt, which
can reach the provider snapshot on the unmounted path; the read now follows
the decision. A seq-less renderer screen would replay every buffered chunk
on top of itself, so the probe keeps the chosen snapshot for it. The probe,
adopt and mount wait move into their own module to stay under the line cap.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(runtime): adopt a seq-less renderer screen when no output is pending

The seq gate only prevents a double replay of buffered output, so a settled
non-blank screen without a seq is safe when nothing is pending. That keeps
the better screen for a pane right after a deferred cold restore, before it
is renderer-ordered. The rule now applies after the mount wait as well.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(runtime): decide renderer attachment from the host's serializer flag

The mounted-pane probe re-derived attachment by serializing the renderer up to six
times, which cost ~7.5 s for a registered but unresponsive renderer on a busy PTY.
The host already holds that fact in the serializer readiness flag. The flag is never
cleared when a pane closes over a live PTY, so one null serializer answer falls back
to the mount wait: worst case is the old 3 s plus one 750 ms serialize.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(runtime): let the serializer's answer alone prove renderer attachment

serializeRendererTerminalBuffer already answers null when the host's serializer flag is
unset, so the separate flag accessor was redundant. The numeric-seq adopt test now
replays only the byte past the seam.

* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a

it. The read is queued again, as it was before the removal.

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

rules through the string proof in their own file rather than the session-file

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is

has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* feat(native-chat): a typed failure fact beside every failure sentence

Adds the shared vocabulary the host writes a failure with: a closed failure kind, a
provider diagnostic that says who it is for (a person, or a log), and a refusal cause
beside the refusal code. Status rows gain an optional failure fact and rejected
submissions an optional rejection fact; the dispatch row carries it, the reducer reads
it field by field, and the projection forwards it. Older rows and older readers are
untouched: every field is optional and the schemas stay open.

* fix(native-chat): durable failure rows and rejection reasons are written for a person

Every host writer that records a failure now writes a sentence for a person beside a
typed fact, instead of embedding a refusal's message, an exception or a composed exit
string. A provider's own words travel as a separate diagnostic from the places Orca
composes them - the Claude and Codex exit stderr (a log), Codex's JSON-RPC message,
Claude's compact_error and Codex's turn error (for a person) - and are never inferred
from a string afterwards. Not signed in and oversized history are typed at the
adapter that detects them.

Covers start and restart failures, the delivery loop, dispatch rejections (content,
queue-full, write failures, provider refusals), cancel and answer confirmation rows,
compaction, the rewind fallback, and not_delivered, which released clients printed
as it was. Two leaks close on the way: a settlement retry no longer writes Orca's
probe evidence into the exit row, and an attach or journal-sink failure is recorded
as Orca's fault rather than as the provider stopping. The legacy rejection markers
and the reasons on sends in doubt stay byte-identical.

* feat(native-chat): refusals name their cause, and a failed start is worded in one place

A refusal now carries an optional cause beside its code: one closed enum of the situations
a chat write can meet, set at every emitter a structured-chat write reaches. Returned
refusals build it with refuse(code, cause, message). Store and host paths that raised a
bare Error(code) now throw AgentSessionRefusalError, whose message is still the code and
which has no code property; the RPC error mapper handles it before any other passthrough,
keeps today's wire code and message byte-identical, and adds { refusal: { code, cause } }
to the error's data. The hold throws it, and restart-resume files the cause beside the
unchanged reason. The operation ledger stores the cause beside the code, so a replay names
the same situation as the first answer. The store fallback copy picks its words and cause
by situation, so a stale replay or a moved lease no longer reads as a latched owner.

Every failed start is worded by structuredAgentSessionStartFailure(cause, context), which
returns the row sentence and the typed fact together; the delivery loop, the exit
settlement and the dispatch that met a starting child all call it. Provider diagnostics
are capped at the lease record's 512 characters wherever a fact is built.

* refactor(native-chat): one reader of why a submission was rejected

classifyDispatchRejection(submission) returns { category, verdict, kind? }. It reads the
typed rejection fact when the row carries one this build can place, and the legacy
markers otherwise - all six, including not_delivered, which released clients printed as
it was. The verdict is null only for a withdrawal, a host restart and a closed chat;
write failures, a full queue and not-delivered stay failures. It replaces
dispatchRejectionReasonIsInternal and every string comparison against the markers: the
outbox reconcile, the rejection notice, and the send disposition, where a replayed
Stop-withdrawn send no longer surfaces as a failed send.

The journal reducer's echo-aliasing guard reads the narrow isWriteFailureSubmission,
which matches the typed kind or the legacy prefix in any dispatch state, so its behaviour
on legacy unknown rows is unchanged.

* test(native-chat): pin provider diagnostics where they are composed

The Claude exit status and stderr, the Codex stderr tail and Codex's JSON-RPC message are
each checked at the place Orca composes its own error around them, so the typed detail
is proven to come from the provider's value and never from Orca's wording.

* fix(native-chat): an attachment Orca refuses says which limit it broke

The content check's refusals (20 images, 5 MB per image, 20 MB in total, supported types) are
written for a person, but the rejection writer replaced them all with one generic sentence.
Each refusal now carries its own sentence, in MB rather than bytes, and the writer records it
beside kind attachmentInvalid. Only an attachment that could not be read keeps the generic
sentence.

* fix(native-chat): the chat tab table refuses with a typed cause

Showing a chat tab refused with bare Error('agent_session_conflict') and
Error('agent_session_identity_required'), the only chat-reachable refusals still thrown without a
cause (opening a chat from history can reach the second when the chat is removed mid-open). Both
now throw the typed refusal; wire code and message are unchanged.

* fix(native-chat): a compaction Codex refuses up front keeps Codex's words

When Codex refused thread/compact/start, the adapter passed on only Orca's wrapped error text and
dropped Codex's own message, so the chat's row read just "Compaction failed." The refusal now
carries Codex's message as the failure detail, as a compaction that fails later already did.

* fix(native-chat): an unreadable chat record no longer promises an update fixes it

The recordUnreadable copy said a newer Orca saved the chat, but the store marks a record
unreadable for damage and key mismatches too, where updating does nothing. The sentence now says
Orca can't read it and gives both next steps.

* fix(native-chat): a restart or a close leaves released clients a sentence, not a marker

host_restarted_before_delivery and provider_closed_before_delivery are not in the markers released
desktop and mobile builds hide, so they printed raw on every rejected message a restart or a chat
close left. Neither marker has shipped. New rows carry a sentence plus kind hostRestarted or
chatClosed, as not_delivered already did; the classifier still reads both markers, and the
verdict for both stays no-failure.

* fix(native-chat): log why an attachment could not be read

The rejected message now says only that the attachment couldn't be read, so the error that said
why (a missing file, a permission, or an unexpected throw) went nowhere. It is logged instead. The
content rejection moves beside the content check that owns its errors.

* refactor(native-chat): drop an unused thrown-refusal cause reader

It had no callers, and its comment claimed it looked through wrappers, which it did not.

* fix(native-chat): a compaction the provider never confirmed is recorded as unconfirmed, not failed

* fix(native-chat): an empty or non-user message is not recorded as a bad attachment

* fix(native-chat): an undelivered preamble's error ends in one period

* refactor(native-chat): a compaction ends as compacted, failed, or unconfirmed, never an unlabelled error

* refactor(native-chat): a failure's sentence is written only from its fact

A writer could choose its sentence and its kind separately, so five writers
put hand-written words beside a fact that said something else. One shared
constructor, agentSessionFailureWords(fact, { surface, agentName }), now
makes both, and the journal types refuse anything else: a status row, a
rejected message or a conversation command that carries a fact must carry
the sentence that constructor branded. Persisted rows keep their shape.

- The sentence table and the restart table move to src/shared, as the English
  default a client copy table can reuse.
- A rejection's legacy markers come from the same constructor. A write
  failure is now the bare `provider_write_failed` marker, which released
  clients already hide; its error goes to the log.
- An image Orca refuses carries which check it failed (and the limit) in the
  fact instead of a sentence; an empty message gets its own kind, and a
  non-user message is Orca's fault.
- The exit row, the interrupted compaction, the /clear failure and the rewind
  placeholder no longer carry their own words beside a fact: the exit row
  says what its fact says, and the placeholder carries no fact.

* fix(native-chat): a start that failed without an observed exit no longer blames the provider

Every untyped start error was recorded as "The provider stopped before it
finished starting.", so an Orca fault, a failed spawn or a close that ended
a start was blamed on the provider. Only an exit the adapter observed says
so now: the Claude adapter marks the error it saw the child exit with, and
anything else is a new `startFailed` kind, "<Agent> couldn't start.", keeping
the provider's diagnostic when the error carried one. A child gone with no
end observed, and a /clear whose new conversation was refused, read the
same way.

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* fix(native-chat): a chat a terminal agent still holds says to quit that agent

The merged base words a restart a terminal agent's claim refused with the
refusal's own message, which names the process. That message is Orca's text
and never reaches a durable row here, so the row read only "<Agent>
couldn't restart." and lost the one step that frees the chat. The restart
sentence now derives it from the refusal's cause: a claimConflicted refusal
adds "This chat is still open in a terminal agent. Quit that agent to
continue the chat here." The live refusal still names the process.

The restart-resume ledger test now sets up a claim the base still refuses:
a terminal owner that is proven running.

* refactor(native-chat): keep the changed files inside their lint limits

The legacy-marker lookup is a table, not a non-exhaustive switch; the
preamble tests read the error without a cast; and the Codex history refusal
goes through a named constructor so its file stays under the line limit.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* refactor(native-chat): refusals carry details keyed by their code

A refusal named its situation with one flat cause list shared by every
code, so nothing stopped a site pairing a code with a situation that code
never means, and the loose fields released clients read (fence, revision,
resolution, verdict, rewind reason) were written by hand at each emitter.

A refusal is now one variant per code with optional details: a reason that
code lists plus that code's own facts. refuse(code, details, message)
rejects a reason the code does not list at compile time, and it is the one
place the loose top-level fields are copied from details, so released
clients read exactly what they read before. A site that cannot name its
situation uses refuseUnclassified, which carries facts but no reason, the
same as an older host; there is no catch-all reason.

Thrown refusals put { refusal: { code, details } } in the RPC error's data
(wire code and message unchanged). The operation ledger, the restart-resume
record and a restart failure's embedded refusal keep details beside the
code and read them back against it; a row an unreleased build wrote with a
cause parses and reads as naming none.

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* test(native-chat): a restart-resume failure keeps its refusal details

The recovery capsule reads a failure's details back against the refusal
code in its reason: facts the code does not list and a reason another code
owns are dropped, and a record an unreleased build wrote with a cause
still parses, naming nothing.

* test(native-chat): import the failure words once in the provider child test

The merge left two imports of the same modules.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* fix(native-chat): a start the provider refused or Orca broke no longer says the provider stopped

A failed start whose cleanup proved the child gone was typed as
`providerStartFailed` whatever failed it: Codex refusing to resume a thread,
a timeout, or Orca's own store fault. The chat then read "The provider
stopped before it finished starting.", which was untrue, and the provider's
own words were dropped. A refused restart also inferred the same from an
`exited` verdict, which only says nothing runs now.

Only an exit the adapter observed names that situation now; anything else
is refused with no reason, keeping its verdict, and the chat reads
"<Agent> couldn't restart.". The provider's words travel host-side from
where the acquisition failed into the start-failure fact's detail, never
onto the refusal, and the sentence does not quote them. What failed is
logged once where the start failed.

* fix(native-chat): a refused /clear start keeps the situation it named

The replacement start that /clear makes built its own start-failure fact,
so a refusal that named its situation, such as not being signed in or a
history too large to restore, was recorded as a bare "couldn't start". It
now takes its fact from the same start-failure function as every other
start, as a new session that failed to start.

* fix(native-chat): the journal schema and comments describe a refusal's details, not its cause

The persisted failure fact's schema still described `refusal.cause`, which
this branch replaced with `details`. It now describes `details` as an
optional open object; a row an earlier build wrote with a `cause` still
parses. A comment and three test descriptions that still named the cause
now name the details.

* fix(native-chat): a Claude child that exits while being acquired still reads as the provider stopping

Now that only an exit the adapter observed says the provider stopped, the
exit the Claude adapter saw during acquisition has to be marked where it is
seen, as the exit after acquisition already is. Without the mark, a Claude
CLI that exited at spawn read "Claude couldn't restart." instead of "The
provider stopped before it finished starting."

* fix(native-chat): word a failed chat start's refusal as its start failure

A chat whose agent failed to start answered the create with the raw error: the launch strip read "Chat could not be started. claude stream-json exited (code 1): claude: not signed in", and the ledger replayed the same text. The first answer and the replay now carry the sentence the chat's start-failure row reads as ("The provider stopped before it finished starting.", "Claude couldn't start.", the not-signed-in and history-too-large sentences), and the raw error goes to the log. A store refusal's code and the unproven-exit marker are unchanged.

* fix(native-chat): show Claude's API retries as one sentence row

While Claude retried a refused request (a 429, say), the chat gained one red row per attempt reading "rate_limit", with the raw retry frame behind Details. Each retry run now writes one warning row that later attempts revise in place: "Claude is rate-limited and retrying." for a rate limit (error `rate_limit` or status 429), and "Claude hit a temporary problem and is retrying." otherwise. The row carries a `providerRetrying` fact with the provider's error type and status, and the frame as a log detail capped at 512 characters.

* fix(native-chat): tell the user to run /clear again when its new conversation can't start

When /clear's replacement conversation failed to start, the result told the user to "send your message again", which would go into the old conversation. The failure words now take the command the start was for, so a failed /clear reads "Codex is not signed in for the selected account. Sign in, then run /clear again.", "Codex couldn't start. Run /clear again." or "The provider stopped before it finished starting. Run /clear again." A message send keeps its wording.

* test(native-chat): expect a failed Claude create to be refused in a sentence

The runtime suites asserted the CLI's stderr reached the create refusal; it now goes to the log and the refusal reads as the chat's start failure.

* fix(native-chat): name the agent that stopped starting and say how to retry a failed start

A start the provider ended now reads "Claude stopped before it finished starting." (or "The agent ..." when the chat's agent is unknown) instead of naming "the provider". A start or restart that failed with a chat left to retry now ends in "Send your message to try again.", or "Run /clear again." for /clear; released clients print only this sentence. A message rejected at dispatch because its child died while starting names the same agent as the start's row.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* fix(native-chat): answer a create refused before spawn in the words its replay reads

A create that failed before any process started threw Orca's own error text as its first answer,
while its replay from the operation ledger read the generic start sentence. The two refusals a
person can act on, a launch whose Anthropic sign-in variables override the managed Claude account
and a Claude account switch in progress, are now typed where they are thrown and worded by the
shared failure constructor, so the first answer and the replay say the same thing. Every other
pre-spawn failure reads the generic start sentence, with its own text in the log. The first answer
keeps its wire code; a message that is itself a code is unchanged.

* fix(native-chat): say how to retry after an agent stopped before it finished starting

"<Agent> stopped before it finished starting." gave no next step outside /clear, unlike every other
failed start. It now ends "Send your message to try again.", the same step a start or restart that
could not run gives; after /clear it still says "Run /clear again."

* fix(native-chat): say how to reach a Claude chat when a WSL Claude account blocks it

A Claude chat that restarts while a Claude account is added in WSL and no Windows Claude account is selected was refused before spawn with Orca's own text as its first answer, and the generic start sentence on replay. The refusal is now typed where the account gate throws, and both answers read the same sentence: choose or add a Windows Claude account in Claude Accounts settings, then send the message again. Account settings that cannot be read name no situation and keep the generic sentence.

* fix(native-chat): say the reason a host names for a refused chat write

A refused Stop, answer, setting, goal, command or queued message now reads the refusal's reason as
well as its code. A code stands for several situations, so the code alone could only say what did
not happen; with the reason, the notice says why and, where the person has a step to take, what it
is: "The agent is still responding. The command didn't run. Wait for the agent to finish
responding, or stop it." The phone uses the same words.

The notice table keys on code, then reason, then the kind of write. Every reason of every code has
an entry, so a reason the host adds does not compile until it has words; a reason whose honest
words are its code's keeps the code's row. A refusal with no reason, or one this build does not
know, reads exactly as before, which is what an older host gets. A start that failed reuses the
failure row's own sentence rather than a second one.

A queued message keeps the reason, the rewind reason and the owner's verdict with its saved
failure, and a rejected one keeps the host's typed fact without its provider detail. Nothing that
moves with the owner or comes from the provider is saved; entries saved before this load as they
were. The saved failure moves to its own module beside the words chosen from it.

* fix(native-chat): retry a refused send under a new id only once its agent is proven gone

A send refused because Orca could not tell who owns the chat keeps its operation id, since the
first attempt may still land. When the refusal also says the agent process has exited, nothing can
run that attempt, so the message moves to its Retry row under a new id instead of holding the queue.

The owner's verdict is read as a floor: a saved `exited` is final, and any other saved verdict never
changes the id on its own. Only a verdict re-derived from the current lease can raise it to
`exited`, and nothing lowers a saved `exited`. Today no host sends a verdict on a send refusal, so
nothing a person sees changes; the rule is in place for the saved verdict a reload reads back.

* fix(native-chat): say a /clear that never finished did not finish, instead of that it cleared the chat

A send into a chat whose /clear started but never committed was refused as if the conversation had been cleared: "This conversation has been cleared. Your message was not sent. Open the current conversation to continue." The clear never finished, so its new conversation may not exist and there is nothing to open. That refusal now has its own reason and reads "The last /clear didn't finish. Your message was not sent. Start a new chat to continue.", which is the only way on today. Its message for released clients says the same: "The last /clear didn't finish. Start a new chat to continue." Only a committed /clear still says the conversation was cleared.

* fix(native-chat): a send the provider never received after a restart has no verdict

Restart reconciliation rejects a crash-stranded send the provider's history
proves it never received. Nobody failed that send, but the verdict table
treated it as a failure. Each rejection kind now has its verdict in one
exhaustive table, so a new kind does not compile until its verdict is chosen;
no verdict for a withdrawal, a host restart, a chat close, or this lost send.

A rejection whose kind this build cannot place, such as one a newer host
added, now reads as undelivered with no verdict instead of falling back to the
reason beside it: all it proves is that the message did not happen. The host
keeps such a fact's kind when it reads the row back, rather than dropping it
and letting the reason decide.

Only kinds that can be why a message was not sent may reject one, by type:
compaction, cancel/answer confirmation and provider-retry kinds stay on status
rows. The one dispatch-row builder takes its input from the type that makes a
rejected row carry its fact.

* fix(native-chat): a send refused after its agent exited keeps its place in the queue

When Orca cannot tell who owns a chat but the refusal says the agent process
has exited, the next attempt may use a new id, since nothing can run the old
one. It no longer marks the message as rejected: nothing recorded it, so it
still holds the head of the queue, and later messages wait behind it instead
of being sent ahead of it.

* fix(native-chat): stop reading a provider's words from an error that contains itself

A cleanup that aggregates errors restarted the depth count for each one, so an
aggregate error that contains itself recursed until the host ran out of stack.
One depth bound now covers both the cause chain and the aggregated errors.

* fix(native-chat): say a chat whose history can't be read can't continue, and to start a new one

A read of a chat's history is refused with `agent_session_journal_unreadable` only when the chat's journal file is corrupt or not a database, which no retry can change. The notice table had no words for a read at all, so a pane had nothing to show but the raw code. Reading a chat's history is now its own request kind, `read-history`, and that refusal on it reads "This chat's history couldn't be read, so it can't continue here. Start a new chat to continue.", whether the host names the reason or raises the bare code. A write refused under the same code keeps its words, because its cause is any failed open, which can clear. Any other read refusal says only "This chat's history couldn't be loaded." `agentSessionReadHistoryRefusalParts(code, details)` gives a pane those words from a read error.

The notice sentences move to their own module so the table stays within its size limit.

* fix(native-chat): decide what every way a child ends means for queued messages in one table

What a child's end means for the messages queued behind it was an if-chain: a user's Stop was checked in one place, a host stop in another, and every other cause, including one added later, fell through to "the provider exited". It is now one table over every end cause, so a new cause does not compile until someone says whether it fails what is queued and how. A user's Stop still fails nothing, a host stop is still Orca's fault, and an exit, a failed attach or an eviction still carry the failure the end recorded. Nothing a person sees changes.

* test(native-chat): a close that stops the child and then fails rejects what is queued by how the child ended

When a chat closes, stops its agent, and then fails a later step, the chat stays open with its messages still queued. The delivery loop then rejects them by the way the child ended: an eviction during startup reads as a failed start, otherwise as the provider having stopped, and either counts as a failure. The cases are rows over the end cause, so another way a chat closes is one more row.

* test(native-chat): type the refusal a persisted-schema test admits

* fix(native-chat): say whether a chat's history is damaged or just couldn't open

A write refused because the chat's journal would not open named one reason, `journalUnreadable`, for every failed open, and a read of the history took that same reason as final. So the words depended on what was asked, not on what happened: a busy or permission-denied open could tell a person to start a new chat, and a damaged one could read as something that clears.

The host now decides at the refusal which it was. `journalCorrupt` is set only when SQLite itself reports the journal damaged or not a database (SQLITE_CORRUPT or SQLITE_NOTADB, extended codes included, read from the driver's result code and never from message text, through any `cause` chain). Every other failed open is `journalUnavailable`. A corrupt history reads "This chat's history couldn't be read, so it can't continue here. Start a new chat to continue.", with "Your message was not sent." before the step on a send. One that couldn't open reads "Orca couldn't open this chat's history right now. Try again.", likewise on a send. A host that names no reason gets "Orca couldn't read this chat's saved history.", which promises neither, because damage can't be proven from the code alone.

The refusal's message, which released clients print for a send, is now that person sentence instead of the open error's own text; the error is logged instead. `journalUnreadable` is replaced outright: no released build wrote it, and a stored one reads as a refusal with no reason.

* docs(native-chat): say why a history that couldn't open names its retry step

* fix(native-chat): a failed start's row keeps the words its rejected messages carry

When the delivery loop settles a failed start before the child's exit is published, it writes the
start's error row and rejects every queued message with the adapter's startup answer. The exit
settlement then rewrote the same row from the exit event, so the row could say one thing while the
rejected messages, which are terminal, said another. The exit now leaves a start's row it finds
already written.

* fix(native-chat): a Claude start Orca itself failed no longer says Claude stopped

Every error that ended a Claude session was marked as an exit the adapter
observed, including a start Orca failed while the CLI was still running: a
saved option whose restore lost its answer, an init frame naming another
session, or a journal write fault. Those read "Claude stopped before it
finished starting." although Claude never stopped on its own. The mark now
stays where the child's exit is seen (the connection's exit callback), so
those starts read "Claude couldn't start." with any diagnostic beside it,
and a real exit before the start lands still says Claude stopped.

* fix(native-chat): name the agent that stopped, and blame Orca for its own closes

A chat that lost its agent mid-response said "The provider stopped…", and a
started Claude session that Orca itself closed after a journal fault said the
same, as if Claude had exited on its own.

The exit row and the rejected-message reason now name the chat's agent ("Claude
stopped while this response was in progress…", "Codex stopped before this
message was sent."), or "The agent" when the name is unknown; the stale-state
settlement now passes the agent name too. After a Claude start has landed, the
ended event reports providerExited only when the child's own exit was observed;
any other close is Orca's fault and reads as one.

* test(native-chat): pin the sidebar verdict to the rejection classifier for every kind and legacy marker

* fix(native-chat): blame Orca, not Codex, when Orca closes the Codex child

A Codex chat that Orca itself closed (a journal sink that could not take a
frame, or a forced close) said "Codex stopped while this response was in
progress", as if Codex had exited on its own.

Orca's own close path now reports hostFault. providerExited is left to the
app-server connection's exit callback, which the connection withholds while Orca
is closing the child, so it only ever reports the child's own exit.

* fix(native-chat): a chat whose history is damaged reads "Unable to load this chat."

* fix(native-chat): route the conversation-outlives-agent writers through the typed refusals

Three writers that arrived with the merge wrote refusals the old way:

- An operation that starts the agent itself, such as a goal change, turned any error the start
  threw into a refusal whose message was Orca's own error text, which released clients print.
  It now logs the error and says only that the agent couldn't restart.
- An option picked while the chat is at rest, for a key the provider would not accept, is refused
  with the rejected-option reason, like the same pick on a running agent.
- A restart continuation whose agent was refused a start filed the rejected message's sentence as
  the failure's reason. It files the refusal's code with its details again, which is what the
  restart-failure guidance keys on.

* fix(native-chat): a start Orca stopped because it never finished reads as that

The idle sweep now stops an agent whose start never finished and rejects the messages waiting on
it. The chat read "Orca ran into a problem, so this didn't go through. Try again." for that,
because every host stop was worded as Orca's own fault. It now reads "Codex never finished
starting, so Orca stopped it." in the chat's row and on each rejected message, carried as its own
failure kind so newer clients can tell it apart. The message counts as failed, like any start that
did not land.

* test(native-chat): pin the merged close and host-stop rows to their typed facts

The merge left two expectations on the old words: the close tests looked for the marker a close
used to write, and the host-stop test for the host-fault sentence. A close now writes "The chat
closed before this message was sent." with its fact, and a host stop the hostStopped sentence the
constructor gives, whatever reason the stop carried. Also folds the conversation command's two

* fix(native-chat): a read of a chat this host cannot open says why

Reads now reach a chat through one accessor, which refused a missing record and a provider this
host does not run as a bare code with nothing beside it. Revealing the same chat already names
those reasons, so a client could tell "this chat no longer exists" and "update Orca" apart there
but not on the history or subscribe read that follows. The accessor now throws the same typed
refusals. The wire code and message are unchanged; the reason rides only in the error's data,
which released clients ignore.

* test(native-chat): a Claude retrying past the idle window keeps its conversation open

Every api_retry frame publishes the journal, and that publish is the activity the idle sweep reads, so a retry run revised into one row still renews the clock on each attempt.

Measured 128s against 172s on ubuntu-latest, with every compute-bound step
faster: type-aware 24s to 15s, anti-slop 28s to 19s, localization extraction
67s to 46s, and the orcad terminal smoke 39s to 14s. Checkout and the install
were unchanged at 12s and 16s.

The toolchain resolves on arm64: both lint engines ship linux-arm64 bindings
(@oxlint/binding-linux-arm64-gnu, @oxlint-tsgolint/linux-arm64), and
build-orcad-bun.mjs derives its target from process.arch. The orcad smoke
booting and round-tripping a real PTY is the evidence that node-pty compiled
and that Bun, the bundled ripgrep and @parcel/watcher all resolved.

The runner is free for public repositories, the same one the typecheck job
already uses.

* fix(orchestration): reland process-incarnation reap for stale worker terminal handles

Relands the orchestration part of #18790, which #22601 reverted in full
because that squash commit also bundled an unannounced agent. Only the
worker terminal-reap fix returns; no agent catalog changes.

When a worker's saved terminal handle stops resolving while its process is
still running, worker-show/read, worker-stop and worker-release now re-mint
a live handle from the recorded process incarnation (exact pty id +
incarnation id, same host scope) and act on it, instead of reporting the
terminal missing and leaving the process running on the host.

Fixes STA-8493

pr.yml:
  cross-version-wire        source-only, tagged checkout plus in-process vitest
  managed_hook_node18       Node 18 publishes linux-arm64; the per-platform

  codex_index_heal_contract @openai/codex ships @openai/codex-linux-arm64
  shell_contracts           fish 4.x is published for noble/arm64, zsh is in the
                            arm64 archive, so the fatal fish-4 gate still holds

mobile.yml:
  verify                    209s of its 298s is Vitest; no Android SDK, emulator,
                            gradle, Hermes or Watchman, no docker, no artifacts.
                            Gemfile.lock lists the generic `ruby` platform, so

  recording-pin             pure Node plus git; the golden comparison masks

                            --platform linux/amd64, and it is where the glibc

                            arch-specific, so flipping would validate the arm64

  relay_integration         no technical blocker, but x86 relay coverage is a

* perf(ci): move xterm_patch_sync to ARM too

The patch check rebuilds 4 packages x 2 builds and byte-compares against the
checked-in bundles. Ran it on darwin-arm64: exit 0, in sync at 1362743 bytes,
with the full fetch-and-rebuild path exercised rather than a short-circuit. The
bundles were generated on Linux x64 and reproduce byte-for-byte on a different
arch and a different OS, so the output is host-independent.

* Fix status bar on smaller screen (#23587)

* fix(status-bar): adapt layout to smaller screens with responsive density

Replace fixed breakpoints with a responsive density system that measures the status bar's content and picks the roomiest density level that fits.

Usage-first collapse order ensures urgent providers stay visible longer.

Electron 43.7.0 threw 'Invalid guestInstanceId' from <webview>'s
disconnectedCallback for a loaded guest (electron/electron#53989), so a
webview React removed and re-inserted kept a dead guest id: the tab went
blank, reload did nothing, and the destroyed listener never fired.
43.7.4 (electron/electron#54097) returns early when the guest is gone.

Raises the runtime floor test to 43.7.4 so a downgrade cannot re-ship it.

* fix(claude): withdraw a follow-up queued behind a stopped turn instead of dropping it silently (#23553)

* fix(claude): withdraw a follow-up queued behind a stopped turn instead of dropping it silently

Orca's SessionStart hook proves most Claude starts before the turn's
system/init, the only frame that advertises interrupt_cancel_queued_v1.
Capabilities were read once from the start proof, so they stayed empty:
Stop never asked Claude to cancel its queue, and the one-at-a-time
fallback withdrew the follow-up without settling it. The send stayed
pending and the chat read Working until the child exited.

Capabilities are now one derived value, taken from whichever report
names any and never cleared by one that names none. The fallback settles
each send the CLI confirms it withdrew.

* test(claude): pin that only a confirmed cancel_async_message counts as withdrawn

* test(native-chat): await the async journal snapshot in the queued-stop test

* test(native-chat): wait for the queued-stop states instead of sleeping

A fixed 20 ms sleep does not cover the host's asynchronous journal writes on a loaded runner.

* fix(codex): a message whose turn was stopped before Codex took it is withdrawn, not stuck (#23618)

* fix(native-chat): land a late settlement from a streamed turn's end after that turn's rows

A settlement that says a streamed turn ended waits for the session's event
sink to drain before writing its dispatch row. The journal reducer still
refuses to overwrite an accepted or rejected send.

* fix(codex): settle a send from the end of the turn Codex answered it into

The turn/start answer names the turn that holds a send. The send's echo
entry now keeps that binding, in memory only. If the bound turn is
interrupted without echoing the send, the send is withdrawn: Codex clears a
turn's pending input on interrupt, so the model never saw it. If the turn
fails first, the send is rejected in Codex's words. A completed turn settles
nothing, since Codex records pending input when it finishes and the echo is
still due. An answer read after its turn already ended is settled by that
end. The echo is still the acceptance and carries the item key.

* test(codex): a send settles from the end of the turn Codex answered it into

The fake Codex keeps 0.157's turn bookkeeping, and can deliver the turn/start
answer after turn/started or after turn/completed. The tests cover:
- a Stop before any echo withdraws the send, and the working rule reads idle;
- a steered follow-up is withdrawn when the turn is interrupted;
- a failed turn rejects the send in Codex's words;
- a completed turn leaves the send to its echo;
- a normal echo and a late echo;
- two steered sends in one turn;
- an answer read after the turn ended;
- a timed-out answer;
- child-thread turns;
- how a binding dies.

* refactor(native-chat): drop the stream flush before a late turn-end settlement

Nothing reads the order of a dispatch row against the turn's terminal row:
the reducer keeps a settled send terminal and the working state is derived
from both. The echo acceptance on the same path never waited either, and the
wait could drop the settlement on a failed sink barrier.

* fix(codex): settle a failed turn's sends at its end, not at its error

Codex keeps a failed turn's pending input and records it after the error
frame, before turn/completed. Settling at the error rejected a steered
follow-up the model had in fact received, so a Retry would send it twice.

* docs(codex): say a completed turn echoes what it took before it ends

Codex records a completed turn's pending input before `turn/completed`, so
a bound send that turn never echoed is left for recovery, not awaiting an
echo. The comments and one test title said the echo was still due.

* test(codex): settle a send whose answer is read after its turn failed or completed

A failed turn that ended before the answer rejects the send in Codex's words,
once; a completed one leaves it admitted and still armed for its echo.

* refactor(codex): read a failed turn's reason with the typed thread-fact reader

* Show a resting Claude chat's effort instead of a blank picker (#23106)

* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and
`queryWindowsProcessRowsFresh` lost their last caller with the handoff. The
fresh-scan tests now go through `queryWindowsProcessDescendants({ fresh: true })`,
the teardown path that still depends on that contract.

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

* refactor(native-chat): drop the transcript helpers only the handoff called

appendLegacyTranscriptMessages fed the terminal transcript catch-up and
proveClaudeTranscriptBranch backed the terminal owner's exit proof. Both lost
their last caller with the handoff. Their tests now go through the live entry
points instead: the roster bounds through the legacy import, the pinned-read and
growth tests through the ancestry replay the history window uses, and the marker
rules through the string proof in their own file rather than the session-file
resolver's.

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is
mid-handoff (<stage>)." in the composer. With the handoff gone, the stages that
reach it are a chat that is still starting, or one whose previous agent process
has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* test(native-chat): type the stand-in roster decoder without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* fix(native-chat): the conversation outlives its agent

Opening a chat no longer starts its agent. A conversation is reached through one host
accessor that opens its journal at rest, and a send is what starts the agent, through
the delivery loop. One idle sweep, every five minutes, stops an agent that has been
quiet for thirty minutes and owes no work, then drops an open journal handle that is
only a cache. Its record, tab, status row and readers stay.

- hold and release are no-ops; hold still builds the host for shipped mobile builds.
- The holders, the holds, the release clock and the exit respawn are deleted.
- Options, the model list, the goal and the context meter answer at rest; a model pick
  at rest is recorded as intent for the next start.
- Compact, rewind, clear and goal changes start the agent first. A send does too when
  a rewind is still in doubt after the conversation opens.
- Orchestration routes mail and group addresses on ownership (the record plus the chat
  tab), not on whether the process runs. An open dispatch keeps its worker running.
- The restart continuation is a send; Resume all holds each slot until the message is
  handed over or rejected.
- A read error never replaces a loaded transcript, and shows the host's own words.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* fix(native-chat): a restart offer ends when the chat's agent starts again

The offer used to end only when the chat's newest user message changed,
because opening a chat started its agent and that start could not be told
apart from real activity. Opening a chat starts nothing now, so the host
reads the fact it already publishes: a chat's status row goes from not
host-owned to host-owned exactly when its agent is started. At that edge the
offer and any failure record for the chat are withdrawn, unless the start is
a resume action's own (its continuation is the oldest undelivered message).

A continuation and a message racing to be first are decided at acceptance:
the continuation is refused, quietly and with nothing filed, when any other
message was accepted since the restart. A failed continuation start leaves
the offer retryable, and each resume action sends its own message id.

Deleted: the newest-user-message comparison, its journal reader, the
continuation filter, and the failure ledger's own "answered by the chat"
check. The marker still carries its message id for one release, so the
previous build can read it.

* fix(runtime): end a transcript stream when its client unsubscribes

Desktop: the IPC subscription controller was dropped as soon as the streaming
handler returned, which for most streams is right after it binds. A later
runtime:unsubscribe then found nothing to abort, so the host kept the subscriber
and derived and sent every publish to a channel no one listened to. The controller
now lives until the renderer unsubscribes, resubscribes the same id, or goes away.

Mobile: disposing an agentSession.subscribe stream now sends agentSession.unsubscribe
with the stream's frame id, so the host ends that subscriber and leaves a sibling
stream on the same socket running. The direct path now passes the frame id the relay
path already passed.

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* fix(native-chat): one fact ends a restart offer: the chat moved on since the restart

The offer is live while no other message has been accepted in the chat since the
restart and its agent has not proved a start since. The offer list, the resume's
reservation check and the continuation's acceptance check all read that one fact,
so a message whose start then failed withdraws the offer too, and a stale click
finds nothing to act on.

The fact is read off the conversation's open handle, which the restart closed, so
it is retired durably whenever it may have changed: a message accepted, a start
proven. A close and reopen within the same run therefore cannot bring the offer
back. A continuation rejected before it reached the agent does not count, so a
retry after a failed start still runs.

Deleted: the quit-time gate on withdrawal, which changed nothing because the
withdrawal and the quit's own offer write share one queue; the per-action
"withdrawn" flag and the separate acceptance check it paired with.

* test(native-chat): an older build reads the restart offer this build records

The offer lives in a file the previous release reads after a downgrade. Pin that
against the pinned release's own capsule, and run the lane when the marker or the
capsule changes.

* fix(native-chat): read a restart offer against where the journal stood when it was taken

"Since the restart" was read off the conversation's open handle, which the idle
sweep closes: after a reopen, a message the user had already sent looked older
than the handle and the withdrawn offer came back.

The offer now records the journal position (epoch and sequence) at the moment
it is taken, and a message accepted after that position, or a journal on another
epoch, means the chat moved on. That is derived from the journal, so it holds
across any number of closes and reopens. An older build's offer has no position;
only a start withdraws it. Because the message half is now durable, the offer is
no longer rewritten in the recovery file on every accepted message; a proven
start still writes it, since only the host that saw the start knows of it.

* test(native-chat): wait for the listing's retire write before reading the recovery file

* fix(native-chat): keep the terminal-backed chat's read error over its local echoes

Messages winning over a read error is right for the structured chat, whose read retries and whose
messages came from the transcript. The terminal-backed view assembles its list from local echoes
too (a launch prompt, a pending send), so a failed read there showed only those bubbles and no
error. Only the structured pane now keeps messages over an error.

* fix(native-chat): a start retries the exit settlement a failed journal write left owed

An agent exit whose journal settlement write failed releases the lease latched until a retry lands.
Reopening the chat used to be that retry; with reveal now only opening the journal, nothing retried
it before the next app launch, and every send was refused. The start the send needs now runs the
retry first, where the attach would.

* perf(native-chat): answer the owner check without opening the chat

Worktree activation calls agentSession.handoffStatus for every chat tab in the worktree, and the
answer comes from the session record alone. Reaching it through the accessor opened each resting
chat's journal (a full read, the crash-boundary write and a restored status publish), then kept it
open for the idle window. It now checks the record and the adapter's support, as before this series,
and opens nothing.

* fix(native-chat): a read waiting on the session lock opens nothing once quit began

The accessor checked for quit before queueing the open, so a read queued behind a session task ran
its open after teardown had begun and indexed a journal no teardown step would close. The check now
runs at the open itself.

* fix(native-chat): read a failed resume's chat before calling it retryable

Whether a failed resume is retryable is the offer's own rule: the chat has not moved on since the
restart, read from its journal. The failure list read it only for a chat already open, so once the
idle sweep closed a chat the user had moved on in, its failure showed Retry again, and the click did
nothing. The list now opens the failed chats first, as the offer list does.

* test(native-chat): type the provider event sink the settlement test reaches for

* fix(native-chat): say the structured read keeps trying only where it does

The structured pane's "Orca keeps trying to load it" line never showed: the view state filled in an
untranslated fallback whenever the read error had no text, and the empty state prefers any message.
The view state now leaves the message out, so the structured pane shows that line and the
terminal-backed pane its own translated one. Mobile's structured lane does not resubscribe after an
error frame, so it no longer makes the claim.

* test(native-chat): await the send's settlement instead of polling for the start

The at-rest send tests polled for the provider start with vi.waitFor's one-second default, which a
loaded machine outran. They now await the host's own settlement of the message.

* fix(native-chat): a restart offer resumes any time after the quit, and knows its own continuations

The continuation's message id was dated by the quit, and the ledger refuses a new id dated more than
a day back, so Resume or Retry a day after quitting was always refused (on main too). It is now
dated by the resume action.

Telling a rejected continuation from the user's own message read the operation ledger, whose rows
expire after about a day; after that a failed resume stopped being retryable. The offer now
records the continuation each action sends on its own capsule entry, bounded to the newest 16, so
the ids end with the offer. The ledger read is deleted.

* fix(orchestration): route no mail to a structured worker its orchestration released

A structured worker is routed on ownership, and a resting worker's lease is released, so ownership
held while its chat tab stayed listed. A worker the coordinator abandoned and then released, found
at rest by the release, therefore still took peer mail and @worktree: broadcasts, and each one
restarted its agent. Routing now also reads the orchestration's own resource row: once it is
released, direct mail, group addressing and worker-show's addressable answer drop the worker, as
they would a terminal worker whose terminal closed. The chat tab stays, and nothing new is stored.

* fix(native-chat): a failed retry names the user's prompt, not Orca's continuation

A resume's continuation is written to the chat before its start, so after a failed attempt the chat's
newest user message is that rejected continuation. A second failure then showed Orca's own restart
text as the chat's prompt. A retry now keeps the prompt its first failure named.

* fix(orchestration): read the released row optionally, as the authority does

worker-show's observation called the row lookup directly, which a runtime double without it threw on
and failed the structured tab-retirement release.

* fix(native-chat): the status bar drops a restart offer the chat moved on from

The renderer re-read the host's restart offer only when a failed chat showed activity, so after a
message withdrew a pending offer the host answered no chats while the status bar kept counting one,
and clicking it opened nothing. The same watch now covers pending offers: a status change in an
offered chat asks the host again, once.

* fix(native-chat): a resting Claude chat shows the effort its next start runs

A running Claude child reports the effort it applies. With no effort pick of
its own, that is what the CLI runs for the model when none is sent, so the
catalog write-through records it as the model's defaultEffort. The store keeps
a known default through a listing that names none, and the resting options
read answers the pick, else that default, as a live child does. Nothing is
saved as the chat's pick.

* test(native-chat): a roster of idle or finished children does not keep an agent awake

The sweep reads owed background work through the shared child-work liveness that upstream's
release clock adopted; a child that went idle or finished is not work the agent still owes.

* fix(orchestration): a task dispatched into a resting structured worker keeps it running

The sweep's open-dispatch check read only the worker-start dispatch that owns the worker's terminal
resource, so a task later dispatched to the same worker (orchestration dispatch --to, which writes a
dispatch with no worker row) did not count: after thirty quiet minutes the worker was stopped while
that task was open, and its coordinator read exited. Any unsettled dispatch addressed to the worker's
process incarnation now counts, derived from the existing rows.

* docs(native-chat): comments stop describing the hold this PR removed

Eight comments still justified orderings and teardown choices by a viewer or dispatch hold that
pinned the provider child. Nothing holds any more; the orderings stand for the binding's redrive
subscription and parked mail, and a chat's agent runs from a send until the idle sweep rests it.
Comment-only.

* fix(native-chat): a restart offer keeps the start its own continuation made

Whose start ended an offer was decided at read time, from whether the offer's continuation was
still the queued message. Once the provider refused that continuation, the child it had started
read as someone else's start, so the offer ended and its failure showed no Retry. The delivery
loop now records which queued message a start is for on the in-memory child, and the child's end
carries it; the offer counts a start as its own when that message is one of its continuations.

* fix(native-chat): an agent gets a full idle window after its owed work ends

The sweep measured quiet only from the last journal row, so once a subagent, command, monitor or
dispatch that had outlived the window ended, the agent was stopped at the next tick. A child can
read done before the lead's wake-up turn writes anything, and stopping in that gap loses the
wake-up. The sweep now counts owed work it observes as activity, which gives the agent the full
window afterwards, as the release clock it replaced did.

* test(claude): the options-read fixture runs a live child

The fixture marked its conversation running with a hasProviderChild field the
session type does not have, so the read took the at-rest path and refused a
session with no record. It now carries a child, which is what the read checks.

* test(native-chat): host tests reach its collaborators through a typed seam

The rest-test rig and three test files read the host's private members with
Reflect.get and cast the result. The host now exposes one test-only accessor,
collaboratorsForTests(), and the subscribers class a subscriberCountForTests()
beside its existing retainedActivityCountForTests(), so the tests are checked
against the real types and the casts are gone.

* refactor(orchestration): one owner answers a structured worker's custody

Routing, group addressing, worker-show and the idle sweep each composed their own reading of
whether orchestration still holds a structured worker, so each new obligation or retirement state
had to be added to every reader. structured-worker-custody now derives both answers from the
worker-terminal list state coordinators see in worker-list: addressable is owned and not released,
and owed work is an active custody or an unsettled task dispatched to the same incarnation. The
owner's state is read through the remote dispatch attachment too, as the terminal transfer lookup
already does. Behaviour is unchanged; a settled worker awaiting its coordinator still rests.

* refactor(orchestration): owed work is an open dispatch on the worker's incarnation

A supervised worker's own dispatch context stays open exactly while the worker is active, so the
separate active-custody branch only repeated it. Owed work is now one fact, which also states the
policy that a worker awaiting its coordinator's decision may rest, and both custody decisions are
written once at the top of the module.

* fix(native-chat): a restart offer knows its continuations by a tag in their id

The offer recorded each continuation id in a list on its capsule entry, capped at 16, and a running
action's id in memory. Both could disagree with the journal: past the cap an old rejected
continuation read as the chat moving on, and a crash during a retry restored the failure's older
entry, which lacked the retry's id. Each continuation id now carries a tag derived from the offer
(its teardown and chat), then the action's own part, so any continuation of this offer, queued or
rejected, is recognised from the journal row and the marker alone. The persisted list, its cap and
the in-memory action map are deleted; the agent-start withdrawal keeps an offer whose own
continuation the start was for, read against the stored marker.

* test(runtime): the legacy-worker reveal test judges its stale snapshot inside the wait

The tui-idle probe reads through readTerminal, which now awaits the structured
worker check before the PTY read, so the probe's snapshot request starts a
microtask later. vi.waitFor missed it on its first check and polled again at
50 ms, the same moment the wait's own 50 ms timeout fired. The stale snapshot
then resolved after the wait had already timed out, so the test passed without
judging it, and the rejection landed before any handler was attached. Vitest
reported that as an unhandled error and failed the shard.

Polling every 1 ms sees the request within a few ms, so the snapshot is judged
while the wait is still pending.

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* fix(native-chat): the idle sweep reads owed work every tick

Owed work counted as activity, but the sweep read it only once the idle window had elapsed, so it
refreshed the clock at most once a window. Work that ended just before the next read left the
agent to be stopped at that read, moments after the work ended, which is the gap the refresh was
meant to cover. The sweep now reads owed work on every tick for a started agent, so the window
always runs from the last tick that saw work owed.

* fix(native-chat): a continuation handed to the agent stays sent

The offer read its own continuation as not reaching the agent while its dispatch was pending, which
also covered one already handed over and still unanswered. When the wait for that answer ended first,
the failure it filed read as retryable, and a retry sent a second continuation to an agent that may
have acted on the first. Only a continuation still queued, or rejected, is now read as unsent.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): the interrupted create's own retry continues again

The merge of main's lease-latch fix replaced that test's retry of the interrupted create, under its
own operation id, with a fresh start whose result nothing read. That fresh start passes with the
released-reservation continuation deleted, so the case the fix exists for went untested. The retry
and its assertion are main's again.

* docs(native-chat): three comments that still had views starting agents

A start with nothing queued now comes from a command, goal change or rewind; an interrupted compaction
left alone would refuse every send, so no agent would ever start to finish it; and a current host
raises the unattached read refusal only once quit began, with the attach window belonging to an older
host.

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* test(native-chat): a reader's open settles the turn a failed exit settlement left running

An exit whose settlement write failed leaves its turn running in the open journal. PR 1's open now
settles it, and this pins the two reads that reach it here: a reader reopening a chat the idle
sweep closed, and a read that opens the chat before the restart restore reaches it.

* test(native-chat): the view-start test's starting window outlasts two subscriptions on a loaded runner

A subscription reads the conversation before it returns, so under load the two views took longer
than the create child's 300 ms start, which then exited before the test checked that it had not.
The child now takes a second to fail.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* test(native-chat): a read that reaches a crashed chat before the startup reconcile settles its turn

On desktop the chat on screen at relaunch reads before startup reconciles the leases, while the
dead process's lease still reads live. The open settles the turn it left running anyway, and the
restore that follows finds it settled.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* docs(native-chat): drop the removed dispatch hold from six comments

A worker's session no longer takes a dispatch hold, and no release clock
rests a chat by visibility; the agent-launch comments, the abandon test,
the teardown test and the refusal census still said so.

* test(native-chat): rest the owner-status chat through the idle sweep, not a hold

The activation-gate test from #22808 put its chat at rest by holding and
releasing it, and passed the release-clock grace. This branch deleted both,
so the case threw before it reached its assertions. It now moves the host's
clock past the idle window and lets the sweep stop the agent and close the
conversation, then asserts the same owner answer and activation gate.

* fix(native-chat): show the structured pane's retrying line when a read fails

The read transport always hands the pane the host's words, so the error
state's "Orca keeps trying to load it" line, which showed only when there
were none, was never seen: the pane showed the host's text twice, as its
subtitle and on the status line under it. The structured pane now always
says its read keeps retrying, and the host's text stays on the status line.
The terminal-backed chat is unchanged.

* fix(native-chat): keep a resting Codex chat's unsaved effort blank, as its live child shows it

The resting options read fell back to the catalog's default effort for every
provider. A live Codex child answers only the effort its thread reported, which
is none when Codex's config names none, so a resting Codex chat showed Medium
and then went blank once it started.

* test(native-chat): read the resting Claude chat from the record its start persisted

The at-rest test built the record by hand, so nothing proved the model id a start
persists is the listed row the catalog learns the default under.

* fix(release): stop the release policy from deleting pipeline-cut releases (#23669)

* fix(release): stop the release policy from deleting pipeline-cut releases

The policy judged a release by who created the release object. Cut Release
reuses an existing draft, so a CI-built v1.4.216 whose draft a person had
created was deleted (tag included) when its notes were edited, and Latest
fell back to v1.4.214 because v1.4.215 was also published by a person.

- Authorize a desktop release when its annotated tag was created by the
  release pipeline and points at its `release: vX` commit, not only by author.
- Only delete on `published`; an edit never deletes a release or tag.
- Pick Latest from the highest authorized stable using the same check.
- Move the policy into config/scripts/release-policy.mjs with tests.

* fix(release): load the policy module from the tagged commit

Release events run the workflow file from the tag's commit, so checking out
the default branch could pair an old workflow with a newer module.

* fix(claude): write only the hook events and statusLine the user's Claude accepts (#23614)

* refactor(claude): name the Claude version module after the hook events it gates

Pure move of claude-session-end-hook-capability.ts and its tests; the next
commit turns its one-event SessionEnd floor into a per-event version table.

* fix(claude): write only the hook events the resolved Claude knows

Claude 1.0.81 through 2.1.100 validate settings.json `hooks` against a
closed event enum and discard the whole file on one unknown name, so
Orca's install made Claude <= 2.1.77 silently ignore the user's env,
permissions and hooks. Each managed event now carries the first Claude
release that knows it (pinned to per-release enums read from the npm
packages), and install, status and the SSH/WSL relay installer write
only the events the resolved Claude accepts. An unresolved version gets
the set every tabled Claude knows; a downgrade removes only Orca's own
entry for an event the older Claude would reject.

* refactor(claude): move the managed Claude hook events into their own module

hook-settings.ts is at its line limit; the event list and its version gate
move out whole so the next change has room.

* fix(claude): an unresolved Claude version never removes Orca's hook entries

A failed or timed-out version probe is no evidence of an old Claude, so it
must not strip StopFailure, PermissionRequest and the other newer events a
version-aware install wrote. With the version unknown, install adds only
the set every tabled Claude knows and leaves every other entry exactly as
it is; only a known version that lacks an event retires Orca's entry.

* fix(claude): gate the core hook events on the Claude release that added them

Claude validates hooks against a closed event list from 1.0.23, not 1.0.81.
The table treated SessionStart, UserPromptSubmit, Stop, SubagentStop,
PreToolUse and PostToolUse as known by every resolved version, so a Claude
from 1.0.23 to 1.0.61 was still sent names it rejects, and it dropped the
whole settings file. Pin each to its first release from the packed enums and
keep the unresolved-version set as its own policy.

* fix(claude): write Orca's statusLine only for a Claude that knows it

Claude 1.0.49 through 1.0.66 also reject any unknown top-level settings
key, and statusLine joined that schema only in 1.0.64. Orca wrote its
statusLine for every Claude, so 1.0.49 to 1.0.63 still dropped the whole
settings file even with the event gate. Gate statusLine on 1.0.64, pinned
by the packed schemas; a known older Claude has Orca's own statusLine
removed along with the opt-out marker, so an upgrade re-adds it. An
unresolved version is now assumed to be 1.0.64, which knows the same core
events and keeps the statusLine install it had before.

* test(claude): a user statusLine opt-out survives a downgrade and upgrade

Retiring Orca's statusLine for a Claude older than 1.0.64 forgets the
install marker only when Orca's own statusLine was removed. Pin that, so
a user who deleted Orca's statusLine is not opted back in by an upgrade.

* test(claude): check the whole written settings file against each strict schema

Claude 1.0.49 through 1.0.66 discard the whole settings file over any
top-level key their schema lacks. The fixture recorded only whether each
release knew statusLine, so a new top-level key Orca wrote would pass every
test. Record each release's top-level keys instead (statusLine is derived
from them), add the hook enums for every packed release in that window,
and check that a real install and a downgrade write only keys and events
each strict release accepts.

* fix(native-chat): a failed Codex turn keeps its failure and "Worked for" (#23514)

* fix(native-chat): a Codex turn's first terminal settlement is final

Codex follows a turn-ending `error` with a failed `turn/completed` for the
same turn. The error settled the turn and dropped its start and attributed
send; the completion then re-settled it from nothing, so the record lost its
start time and flipped from completed/failure to interrupted/failure. A
failed turn lost its "Worked for" and read as interrupted.

Both ends now go through one settlement that refuses a turn already in the
recent-turns window, so every later end (error then completion, a duplicate
completion) adds nothing and overwrites nothing.

* test(native-chat): the settles-once fixture is an ordinary failed turn

The fixture was labelled and worded as a failed compaction; this change
covers the ordinary-turn path, so its frames now read as one.

* test(native-chat): a failed Codex turn keeps its record when its two ends coalesce in the queue

* fix(terminal): stop guessing that apps died and wiping their keyboard modes (#23584)

* fix(terminal): stop guessing that apps died and wiping their keyboard modes

The renderer wiped xterm's Kitty keyboard flags on every Ctrl+C, every live
reattach, and every Windows agent turn end, though the app usually survives.
xterm then encoded keys in legacy form while the pane mirror Orca's shortcut
policy reads still held the negotiated flags, so Cmd+C, Shift+Enter,
Option/Alt and IME commits disagreed with each other and with the app.

- Delete the Ctrl+C wipe, the ConPTY agent-idle wipe, and the mirror reset on
  every PTY exit (it also ran on unverified host-loss exits).
- Live reattach profiles no longer reset Kitty; every replay epilogue instead
  re-asserts the mirror's flags (pop-all, then the host-proven set; a bare pop
  while unproven), so a revealed xterm gets the live app's flags back.
- Route every renderer-originated mode write through one scanning writer so
  xterm and the mirror always parse the same bytes: confirmed-shell reset,
  hibernate, cold restore, and a full process-boundary ground at fresh spawn.
- Read Kitty flags as 0 where the protocol is withheld (ConPTY), since xterm
  ignores CSI u there but the mirror still scans it.
- The dashboard popout restores snapshot flags as bytes so its xterm agrees.

* style(terminal): separate the kitty restore builder from the pen reset

* fix(terminal): let the kitty mirror own the withheld-protocol rule

Review follow-ups for the stop-guessing change:

- The mirror takes a `kittyKeyboard` option from the xterm's advertisement
  and ignores CSI u when withheld, as xterm does, replacing a per-reader
  helper that any new reader could skip. Daemon/headless users keep the
  default.
- Replay epilogues are writers (`writeReplayEpilogue`,
  `writeReattachReplayReset`) that take the sync or async xterm writer, so
  nothing that looks like a builder mutates the mirror.
- An abandoned hidden restore re-asserts the mirror's kitty flags after the
  byte-gap reset: its discarded chunks were already scanned.
- Tests pin a non-zero host restore (epilogue ends `=31u`, mirror 31), a
  withheld pane staying at 0, and the restart-in-place ground landing after
  the mirror reset; the epilogue test helper is now an exact builder.

* refactor(terminal): one epilogue writer and one scanned ground per boundary

- Reattach callers write `chooseReattachReplayReset(...)` through
  `writeReplayEpilogue`, dropping the second writer from the session.
- Fresh spawn and cold restore rely on their scanned ground alone: it leaves
  the mirror known at 0 with a proven baseline, so the extra reset() was dead.

* feat(terminal): add Reset Terminal that grounds input modes on the host and the pane

An app that crashes where the host sees no command end (no shell hooks, after
exec bash, inside a manual ssh) keeps its Kitty, mouse, paste and focus modes.
Reset Terminal grounds them in every model that can re-arm them: the pane's
xterm and Kitty mirror, the daemon emulator, records and lifecycle scanner, the
relay replay buffer, and main's headless model, so park/reveal, reattach and
reload stay grounded.

Each holder grounds its own model at the request, like Clear Screen. A zero-raw
in-stream span would be dropped by SSH credit delivery and is ambiguous under
snapshot-seq dedup. The host request is a sibling of clear, not a field on it,
because an older host would ignore the field and clear scrollback instead.

* test(e2e): Reset Terminal grounds an unhooked crash's modes through park and reveal

* test(runtime): pin Reset Terminal's headless snapshot to a proven 0 kitty flag

* fix(terminal): ground main's provider mode tracker in arrival order on Reset Terminal

onPtyData scans live bytes into the tracker on arrival, so a ground queued on
the headless write chain could land after a newer ?1049h and leave the tracker
grounded while the emulator stays on the alternate screen. Also pass the
serializer registry's clear/reset hooks as an options object.

* fix(terminal): ground in-flight provider snapshot captures on Reset Terminal

onPtyData feeds both the settled provider mode tracker and any in-flight
capture's live tracker; the reset grounded only the first, so a capture whose
request predated the reset could republish the pre-reset alternate screen.
Share one scanProviderModeTrackers for both. Cover the pty:resetInputModes IPC
handler and the runtime controller's host-window request.

Jinwoo Hong 9b46c3f0f2 fix(terminal): let unselected Cmd+C reach apps that own their selection (#23597)
* fix(terminal): let unselected Cmd+C reach apps that negotiated kitty keyboard

On macOS Orca swallowed an unselected Cmd+C as a no-op copy, so a full-screen
TUI like Codex, which captures the mouse and keeps its highlight out of xterm's
selection, never received its own copy chord.

- isAppOwnedCopyChord (xterm-bypass-policy) is the one rule: macOS, no xterm
  selection, and non-zero kitty flags from the pane's mirror. The pane's xterm
  bypass and the dashboard popout's key handler both use it.
- A selection copy stays claimed through its repeats and release, including
  custom copy bindings, so kitty event reporting cannot leak them to the PTY.
- Plain shells keep sending nothing; Linux and Windows are unchanged.
- The e2e kitty helpers move to helpers/terminal-kitty-keyboard.ts so the
  shortcut spec stays under the line limit.

* fix(terminal): popout copy ownership reads xterm's selection like the pane

A highlight of blank cells trims to empty text but is still a selection, so the
popout must not hand that Cmd+C to a kitty app while the pane withholds it.

* test(terminal): keep the held-copy binding test beside the copy dispatch tests

The shortcut-policy suite is at its line limit.

* test(terminal): stub a blank-cell selection without widening the preview harness type

* style(terminal): tighten the app-owned copy comment and read the popout selection after the early return

Brennan Benson 84daac2de4 test(e2e): take the sidebar measured-row baseline with reduced motion (#23588)
The fixture's collapse starts a row-removal slide; on hidden Linux windows the
animation clock can stall, so the 'settled' baseline read LaunchStack 94px low
(104 vs the resting 10). Emulate reduced motion, as the active-delete scroll
spec already does, so the baseline is the resting layout.

Jinwoo Hong 3eac4d93d3 fix(terminal): stop guessing that apps died and wiping their keyboard modes (#23584)
* fix(terminal): stop guessing that apps died and wiping their keyboard modes

The renderer wiped xterm's Kitty keyboard flags on every Ctrl+C, every live
reattach, and every Windows agent turn end, though the app usually survives.
xterm then encoded keys in legacy form while the pane mirror Orca's shortcut
policy reads still held the negotiated flags, so Cmd+C, Shift+Enter,
Option/Alt and IME commits disagreed with each other and with the app.

- Delete the Ctrl+C wipe, the ConPTY agent-idle wipe, and the mirror reset on
  every PTY exit (it also ran on unverified host-loss exits).
- Live reattach profiles no longer reset Kitty; every replay epilogue instead
  re-asserts the mirror's flags (pop-all, then the host-proven set; a bare pop
  while unproven), so a revealed xterm gets the live app's flags back.
- Route every renderer-originated mode write through one scanning writer so
  xterm and the mirror always parse the same bytes: confirmed-shell reset,
  hibernate, cold restore, and a full process-boundary ground at fresh spawn.
- Read Kitty flags as 0 where the protocol is withheld (ConPTY), since xterm
  ignores CSI u there but the mirror still scans it.
- The dashboard popout restores snapshot flags as bytes so its xterm agrees.

* style(terminal): separate the kitty restore builder from the pen reset

* fix(terminal): let the kitty mirror own the withheld-protocol rule

Review follow-ups for the stop-guessing change:

- The mirror takes a `kittyKeyboard` option from the xterm's advertisement
  and ignores CSI u when withheld, as xterm does, replacing a per-reader
  helper that any new reader could skip. Daemon/headless users keep the
  default.
- Replay epilogues are writers (`writeReplayEpilogue`,
  `writeReattachReplayReset`) that take the sync or async xterm writer, so
  nothing that looks like a builder mutates the mirror.
- An abandoned hidden restore re-asserts the mirror's kitty flags after the
  byte-gap reset: its discarded chunks were already scanned.
- Tests pin a non-zero host restore (epilogue ends `=31u`, mirror 31), a
  withheld pane staying at 0, and the restart-in-place ground landing after
  the mirror reset; the epilogue test helper is now an exact builder.

* refactor(terminal): one epilogue writer and one scanned ground per boundary

- Reattach callers write `chooseReattachReplayReset(...)` through
  `writeReplayEpilogue`, dropping the second writer from the session.
- Fresh spawn and cold restore rely on their scanned ground alone: it leaves
  the mirror known at 0 with a proven baseline, so the extra reset() was dead.

Brennan BensonandClaude 7a24d3d335 fix(native-chat): the conversation outlives its agent (#22835)
* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and
`queryWindowsProcessRowsFresh` lost their last caller with the handoff. The
fresh-scan tests now go through `queryWindowsProcessDescendants({ fresh: true })`,
the teardown path that still depends on that contract.

* docs(native-chat): stop citing the removed handoff in lifecycle comments

Six comments still named the handoff coordinator, a handoff suspend, or a
terminal-owned session as live participants in the flows they describe.

* test(native-chat): pin that a start dead before proving owes no settlement

The removed restart handoff test pinned this branch; nothing else did.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

* refactor(native-chat): drop the transcript helpers only the handoff called

appendLegacyTranscriptMessages fed the terminal transcript catch-up and
proveClaudeTranscriptBranch backed the terminal owner's exit proof. Both lost
their last caller with the handoff. Their tests now go through the live entry
points instead: the roster bounds through the legacy import, the pinned-read and
growth tests through the ancestry replay the history window uses, and the marker
rules through the string proof in their own file rather than the session-file
resolver's.

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is
mid-handoff (<stage>)." in the composer. With the handoff gone, the stages that
reach it are a chat that is still starting, or one whose previous agent process
has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* test(native-chat): type the stand-in roster decoder without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* fix(native-chat): the conversation outlives its agent

Opening a chat no longer starts its agent. A conversation is reached through one host
accessor that opens its journal at rest, and a send is what starts the agent, through
the delivery loop. One idle sweep, every five minutes, stops an agent that has been
quiet for thirty minutes and owes no work, then drops an open journal handle that is
only a cache. Its record, tab, status row and readers stay.

- hold and release are no-ops; hold still builds the host for shipped mobile builds.
- The holders, the holds, the release clock and the exit respawn are deleted.
- Options, the model list, the goal and the context meter answer at rest; a model pick
  at rest is recorded as intent for the next start.
- Compact, rewind, clear and goal changes start the agent first. A send does too when
  a rewind is still in doubt after the conversation opens.
- Orchestration routes mail and group addresses on ownership (the record plus the chat
  tab), not on whether the process runs. An open dispatch keeps its worker running.
- The restart continuation is a send; Resume all holds each slot until the message is
  handed over or rejected.
- A read error never replaces a loaded transcript, and shows the host's own words.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* fix(native-chat): a restart offer ends when the chat's agent starts again

The offer used to end only when the chat's newest user message changed,
because opening a chat started its agent and that start could not be told
apart from real activity. Opening a chat starts nothing now, so the host
reads the fact it already publishes: a chat's status row goes from not
host-owned to host-owned exactly when its agent is started. At that edge the
offer and any failure record for the chat are withdrawn, unless the start is
a resume action's own (its continuation is the oldest undelivered message).

A continuation and a message racing to be first are decided at acceptance:
the continuation is refused, quietly and with nothing filed, when any other
message was accepted since the restart. A failed continuation start leaves
the offer retryable, and each resume action sends its own message id.

Deleted: the newest-user-message comparison, its journal reader, the
continuation filter, and the failure ledger's own "answered by the chat"
check. The marker still carries its message id for one release, so the
previous build can read it.

* fix(runtime): end a transcript stream when its client unsubscribes

Desktop: the IPC subscription controller was dropped as soon as the streaming
handler returned, which for most streams is right after it binds. A later
runtime:unsubscribe then found nothing to abort, so the host kept the subscriber
and derived and sent every publish to a channel no one listened to. The controller
now lives until the renderer unsubscribes, resubscribes the same id, or goes away.

Mobile: disposing an agentSession.subscribe stream now sends agentSession.unsubscribe
with the stream's frame id, so the host ends that subscriber and leaves a sibling
stream on the same socket running. The direct path now passes the frame id the relay
path already passed.

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* fix(native-chat): one fact ends a restart offer: the chat moved on since the restart

The offer is live while no other message has been accepted in the chat since the
restart and its agent has not proved a start since. The offer list, the resume's
reservation check and the continuation's acceptance check all read that one fact,
so a message whose start then failed withdraws the offer too, and a stale click
finds nothing to act on.

The fact is read off the conversation's open handle, which the restart closed, so
it is retired durably whenever it may have changed: a message accepted, a start
proven. A close and reopen within the same run therefore cannot bring the offer
back. A continuation rejected before it reached the agent does not count, so a
retry after a failed start still runs.

Deleted: the quit-time gate on withdrawal, which changed nothing because the
withdrawal and the quit's own offer write share one queue; the per-action
"withdrawn" flag and the separate acceptance check it paired with.

* test(native-chat): an older build reads the restart offer this build records

The offer lives in a file the previous release reads after a downgrade. Pin that
against the pinned release's own capsule, and run the lane when the marker or the
capsule changes.

* fix(native-chat): read a restart offer against where the journal stood when it was taken

"Since the restart" was read off the conversation's open handle, which the idle
sweep closes: after a reopen, a message the user had already sent looked older
than the handle and the withdrawn offer came back.

The offer now records the journal position (epoch and sequence) at the moment
it is taken, and a message accepted after that position, or a journal on another
epoch, means the chat moved on. That is derived from the journal, so it holds
across any number of closes and reopens. An older build's offer has no position;
only a start withdraws it. Because the message half is now durable, the offer is
no longer rewritten in the recovery file on every accepted message; a proven
start still writes it, since only the host that saw the start knows of it.

* test(native-chat): wait for the listing's retire write before reading the recovery file

* fix(native-chat): keep the terminal-backed chat's read error over its local echoes

Messages winning over a read error is right for the structured chat, whose read retries and whose
messages came from the transcript. The terminal-backed view assembles its list from local echoes
too (a launch prompt, a pending send), so a failed read there showed only those bubbles and no
error. Only the structured pane now keeps messages over an error.

* fix(native-chat): a start retries the exit settlement a failed journal write left owed

An agent exit whose journal settlement write failed releases the lease latched until a retry lands.
Reopening the chat used to be that retry; with reveal now only opening the journal, nothing retried
it before the next app launch, and every send was refused. The start the send needs now runs the
retry first, where the attach would.

* perf(native-chat): answer the owner check without opening the chat

Worktree activation calls agentSession.handoffStatus for every chat tab in the worktree, and the
answer comes from the session record alone. Reaching it through the accessor opened each resting
chat's journal (a full read, the crash-boundary write and a restored status publish), then kept it
open for the idle window. It now checks the record and the adapter's support, as before this series,
and opens nothing.

* fix(native-chat): a read waiting on the session lock opens nothing once quit began

The accessor checked for quit before queueing the open, so a read queued behind a session task ran
its open after teardown had begun and indexed a journal no teardown step would close. The check now
runs at the open itself.

* fix(native-chat): read a failed resume's chat before calling it retryable

Whether a failed resume is retryable is the offer's own rule: the chat has not moved on since the
restart, read from its journal. The failure list read it only for a chat already open, so once the
idle sweep closed a chat the user had moved on in, its failure showed Retry again, and the click did
nothing. The list now opens the failed chats first, as the offer list does.

* test(native-chat): type the provider event sink the settlement test reaches for

* fix(native-chat): say the structured read keeps trying only where it does

The structured pane's "Orca keeps trying to load it" line never showed: the view state filled in an
untranslated fallback whenever the read error had no text, and the empty state prefers any message.
The view state now leaves the message out, so the structured pane shows that line and the
terminal-backed pane its own translated one. Mobile's structured lane does not resubscribe after an
error frame, so it no longer makes the claim.

* test(native-chat): await the send's settlement instead of polling for the start

The at-rest send tests polled for the provider start with vi.waitFor's one-second default, which a
loaded machine outran. They now await the host's own settlement of the message.

* fix(native-chat): a restart offer resumes any time after the quit, and knows its own continuations

The continuation's message id was dated by the quit, and the ledger refuses a new id dated more than
a day back, so Resume or Retry a day after quitting was always refused (on main too). It is now
dated by the resume action.

Telling a rejected continuation from the user's own message read the operation ledger, whose rows
expire after about a day; after that a failed resume stopped being retryable. The offer now
records the continuation each action sends on its own capsule entry, bounded to the newest 16, so
the ids end with the offer. The ledger read is deleted.

* fix(orchestration): route no mail to a structured worker its orchestration released

A structured worker is routed on ownership, and a resting worker's lease is released, so ownership
held while its chat tab stayed listed. A worker the coordinator abandoned and then released, found
at rest by the release, therefore still took peer mail and @worktree: broadcasts, and each one
restarted its agent. Routing now also reads the orchestration's own resource row: once it is
released, direct mail, group addressing and worker-show's addressable answer drop the worker, as
they would a terminal worker whose terminal closed. The chat tab stays, and nothing new is stored.

* fix(native-chat): a failed retry names the user's prompt, not Orca's continuation

A resume's continuation is written to the chat before its start, so after a failed attempt the chat's
newest user message is that rejected continuation. A second failure then showed Orca's own restart
text as the chat's prompt. A retry now keeps the prompt its first failure named.

* fix(orchestration): read the released row optionally, as the authority does

worker-show's observation called the row lookup directly, which a runtime double without it threw on
and failed the structured tab-retirement release.

* fix(native-chat): the status bar drops a restart offer the chat moved on from

The renderer re-read the host's restart offer only when a failed chat showed activity, so after a
message withdrew a pending offer the host answered no chats while the status bar kept counting one,
and clicking it opened nothing. The same watch now covers pending offers: a status change in an
offered chat asks the host again, once.

* test(native-chat): a roster of idle or finished children does not keep an agent awake

The sweep reads owed background work through the shared child-work liveness that upstream's
release clock adopted; a child that went idle or finished is not work the agent still owes.

* fix(orchestration): a task dispatched into a resting structured worker keeps it running

The sweep's open-dispatch check read only the worker-start dispatch that owns the worker's terminal
resource, so a task later dispatched to the same worker (orchestration dispatch --to, which writes a
dispatch with no worker row) did not count: after thirty quiet minutes the worker was stopped while
that task was open, and its coordinator read exited. Any unsettled dispatch addressed to the worker's
process incarnation now counts, derived from the existing rows.

* docs(native-chat): comments stop describing the hold this PR removed

Eight comments still justified orderings and teardown choices by a viewer or dispatch hold that
pinned the provider child. Nothing holds any more; the orderings stand for the binding's redrive
subscription and parked mail, and a chat's agent runs from a send until the idle sweep rests it.
Comment-only.

* fix(native-chat): a restart offer keeps the start its own continuation made

Whose start ended an offer was decided at read time, from whether the offer's continuation was
still the queued message. Once the provider refused that continuation, the child it had started
read as someone else's start, so the offer ended and its failure showed no Retry. The delivery
loop now records which queued message a start is for on the in-memory child, and the child's end
carries it; the offer counts a start as its own when that message is one of its continuations.

* fix(native-chat): an agent gets a full idle window after its owed work ends

The sweep measured quiet only from the last journal row, so once a subagent, command, monitor or
dispatch that had outlived the window ended, the agent was stopped at the next tick. A child can
read done before the lead's wake-up turn writes anything, and stopping in that gap loses the
wake-up. The sweep now counts owed work it observes as activity, which gives the agent the full
window afterwards, as the release clock it replaced did.

* test(claude): the options-read fixture runs a live child

The fixture marked its conversation running with a hasProviderChild field the
session type does not have, so the read took the at-rest path and refused a
session with no record. It now carries a child, which is what the read checks.

* test(native-chat): host tests reach its collaborators through a typed seam

The rest-test rig and three test files read the host's private members with
Reflect.get and cast the result. The host now exposes one test-only accessor,
collaboratorsForTests(), and the subscribers class a subscriberCountForTests()
beside its existing retainedActivityCountForTests(), so the tests are checked
against the real types and the casts are gone.

* refactor(orchestration): one owner answers a structured worker's custody

Routing, group addressing, worker-show and the idle sweep each composed their own reading of
whether orchestration still holds a structured worker, so each new obligation or retirement state
had to be added to every reader. structured-worker-custody now derives both answers from the
worker-terminal list state coordinators see in worker-list: addressable is owned and not released,
and owed work is an active custody or an unsettled task dispatched to the same incarnation. The
owner's state is read through the remote dispatch attachment too, as the terminal transfer lookup
already does. Behaviour is unchanged; a settled worker awaiting its coordinator still rests.

* refactor(orchestration): owed work is an open dispatch on the worker's incarnation

A supervised worker's own dispatch context stays open exactly while the worker is active, so the
separate active-custody branch only repeated it. Owed work is now one fact, which also states the
policy that a worker awaiting its coordinator's decision may rest, and both custody decisions are
written once at the top of the module.

* fix(native-chat): a restart offer knows its continuations by a tag in their id

The offer recorded each continuation id in a list on its capsule entry, capped at 16, and a running
action's id in memory. Both could disagree with the journal: past the cap an old rejected
continuation read as the chat moving on, and a crash during a retry restored the failure's older
entry, which lacked the retry's id. Each continuation id now carries a tag derived from the offer
(its teardown and chat), then the action's own part, so any continuation of this offer, queued or
rejected, is recognised from the journal row and the marker alone. The persisted list, its cap and
the in-memory action map are deleted; the agent-start withdrawal keeps an offer whose own
continuation the start was for, read against the stored marker.

* test(runtime): the legacy-worker reveal test judges its stale snapshot inside the wait

The tui-idle probe reads through readTerminal, which now awaits the structured
worker check before the PTY read, so the probe's snapshot request starts a
microtask later. vi.waitFor missed it on its first check and polled again at
50 ms, the same moment the wait's own 50 ms timeout fired. The stale snapshot
then resolved after the wait had already timed out, so the test passed without
judging it, and the rejection landed before any handler was attached. Vitest
reported that as an unhandled error and failed the shard.

Polling every 1 ms sees the request within a few ms, so the snapshot is judged
while the wait is still pending.

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* fix(native-chat): the idle sweep reads owed work every tick

Owed work counted as activity, but the sweep read it only once the idle window had elapsed, so it
refreshed the clock at most once a window. Work that ended just before the next read left the
agent to be stopped at that read, moments after the work ended, which is the gap the refresh was
meant to cover. The sweep now reads owed work on every tick for a started agent, so the window
always runs from the last tick that saw work owed.

* fix(native-chat): a continuation handed to the agent stays sent

The offer read its own continuation as not reaching the agent while its dispatch was pending, which
also covered one already handed over and still unanswered. When the wait for that answer ended first,
the failure it filed read as retryable, and a retry sent a second continuation to an agent that may
have acted on the first. Only a continuation still queued, or rejected, is now read as unsent.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): the interrupted create's own retry continues again

The merge of main's lease-latch fix replaced that test's retry of the interrupted create, under its
own operation id, with a fresh start whose result nothing read. That fresh start passes with the
released-reservation continuation deleted, so the case the fix exists for went untested. The retry
and its assertion are main's again.

* docs(native-chat): three comments that still had views starting agents

A start with nothing queued now comes from a command, goal change or rewind; an interrupted compaction
left alone would refuse every send, so no agent would ever start to finish it; and a current host
raises the unattached read refusal only once quit began, with the attach window belonging to an older
host.

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* test(native-chat): a reader's open settles the turn a failed exit settlement left running

An exit whose settlement write failed leaves its turn running in the open journal. PR 1's open now
settles it, and this pins the two reads that reach it here: a reader reopening a chat the idle
sweep closed, and a read that opens the chat before the restart restore reaches it.

* test(native-chat): the view-start test's starting window outlasts two subscriptions on a loaded runner

A subscription reads the conversation before it returns, so under load the two views took longer
than the create child's 300 ms start, which then exited before the test checked that it had not.
The child now takes a second to fail.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* test(native-chat): a read that reaches a crashed chat before the startup reconcile settles its turn

On desktop the chat on screen at relaunch reads before startup reconciles the leases, while the
dead process's lease still reads live. The open settles the turn it left running anyway, and the
restore that follows finds it settled.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* docs(native-chat): drop the removed dispatch hold from six comments

A worker's session no longer takes a dispatch hold, and no release clock
rests a chat by visibility; the agent-launch comments, the abandon test,
the teardown test and the refusal census still said so.

* test(native-chat): rest the owner-status chat through the idle sweep, not a hold

The activation-gate test from #22808 put its chat at rest by holding and
releasing it, and passed the release-clock grace. This branch deleted both,
so the case threw before it reached its assertions. It now moves the host's
clock past the idle window and lets the sweep stop the agent and close the
conversation, then asserts the same owner answer and activation gate.

* fix(native-chat): show the structured pane's retrying line when a read fails

The read transport always hands the pane the host's words, so the error
state's "Orca keeps trying to load it" line, which showed only when there
were none, was never seen: the pane showed the host's text twice, as its
subtitle and on the status line under it. The structured pane now always
says its read keeps retrying, and the host's text stays on the status line.
The terminal-backed chat is unchanged.

* test(native-chat): wait for a send's background start before the refusal oracle removes its store

An accepted send wakes the delivery loop, which starts the agent in the background. The oracle's teardown disposed the loop but did not wait for that start, so its lease write could create a temp file in the store directory while the directory was being removed, failing the test with ENOTEMPTY about one run in four. The teardown now drains tracked starts before it closes the journals.

* fix(native-chat): a start a message waited on gets one failure row, the delivery loop's

When a queued message's start failed, two writers could report it under the same row: the delivery loop, when the adapter settled the start without proving it, and the exit settlement, when the child's exit landed. The last one won, so the chat's row could name a different cause than the one the message was rejected with, or be written twice.

The exit settlement now writes the start's row only when no message is queued and the loop has not already recorded that start. A start for a command, goal change or rewind, with nothing queued, still gets its row from the exit.

Brennan BensonandClaude 85067494a1 fix(native-chat): a request that failed reads as failed (#22944)
* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and
`queryWindowsProcessRowsFresh` lost their last caller with the handoff. The
fresh-scan tests now go through `queryWindowsProcessDescendants({ fresh: true })`,
the teardown path that still depends on that contract.

* docs(native-chat): stop citing the removed handoff in lifecycle comments

Six comments still named the handoff coordinator, a handoff suspend, or a
terminal-owned session as live participants in the flows they describe.

* test(native-chat): type the stalled snapshot drain without a cast

* test(native-chat): pin that a start dead before proving owes no settlement

The removed restart handoff test pinned this branch; nothing else did.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

* refactor(native-chat): drop the transcript helpers only the handoff called

appendLegacyTranscriptMessages fed the terminal transcript catch-up and
proveClaudeTranscriptBranch backed the terminal owner's exit proof. Both lost
their last caller with the handoff. Their tests now go through the live entry
points instead: the roster bounds through the legacy import, the pinned-read and
growth tests through the ancestry replay the history window uses, and the marker
rules through the string proof in their own file rather than the session-file
resolver's.

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is
mid-handoff (<stage>)." in the composer. With the handoff gone, the stages that
reach it are a chat that is still starting, or one whose previous agent process
has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* test(native-chat): type the stand-in roster decoder without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* fix(native-chat): a request that failed reads as failed

A structured chat whose only message the agent's start refused read as a
green finish, and a cancelled structured turn did too: the host published a
verdict only for turn records, and structured rows carried no `interrupted`.

The host projection now reads the session's latest request: its turn's
outcome, or `failure` for a send the agent or its start refused. A send
that was withdrawn, or left undelivered by a restart or a close, fails
nobody and makes nothing listable. The ingest publishes `interrupted` as the
hook lanes do, and every reader decodes the verdict through one accessor, so
a failure reads Failed on the dot, the rollups, history and `worktree ps`,
behaves like a cancellation in every clean-finish policy, and notifies as
"failed".

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): a verdict change republishes the mobile status projection

* refactor(native-chat): the store's retention trigger keeps its flag compare

A verdict change always moves the completion clock the same check already
reads, so a second verdict compare there caught nothing new.

* test(native-chat): a user message the provider journaled keeps its session listed

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* fix(native-chat): a late provider-session update keeps a failed recovery record failed

A provider-session heartbeat that rewrites a completed recovery record kept
its interrupted flag but dropped the outcome it was copied with, so a live
failed checkpoint read as a clean finish until the next status write.

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* test(native-chat): the terminal-bell check asserts the renamed verdict field

The bell notification test still checked for agentInterrupted, which no
longer exists, so it could not catch a verdict leaking into a bell dispatch.

* fix(native-chat): a failed turn ranks like a completion for attention

Attention readers (completion time, Smart Sort, sticky retention, Cmd+J
Recent) now demote only a turn the user stopped. A failure is news the
user has not seen, so it keeps its completion time, ranks in the Done
class, stays retained after its pane goes away, and a retained failure
reads failed in the worktree rollup instead of done. Clean-finish
policy (hibernation, pane ownership, the value moment) still treats a
failure like a stop.

The retention trigger compares verdicts again: success -> failure no
longer moves the completion clock.

* fix(native-chat): a failed main agent reads failed while its subagents still work

The verdict is now read from the main agent's own state, not the folded
row: a main agent that is done and failed has a verdict even while its
subagents keep the row working. Without mainAgent (history, worktree ps,
older hosts) the old combined-done rule stands.

Display marks the verdict through agentVerdictDisplayMark: a failure
outranks every combined state on the agent's dot, label, tab badge,
dashboard and activity rows; a stop marks only a done row, so a
successful or stopped main agent with live subagents still reads
working. Subagent rows keep their own state. The worktree card, terminal
tab and Cmd+J rollups share one pane fold and rank a pending question,
then failed, then working, monitoring, interrupted and done.

worktree ps publishes the main agent's outcome on a working row, and the
mobile mirror reads it. The store's change check, the paired-client
mirror's equality and its epoch now see a verdict change on a working
row, which otherwise moves no state or clock and left the worktree card
reading working. Clean-finish policy is unchanged: a working row is never
hibernated and has no completion time.

* docs(native-chat): the worktree ps outcome comment no longer claims old hosts send it

The field is new: an old host sends no outcome at all, so a reader falls
back to interrupted. The removed clause said old hosts send it on done
rows, which never shipped.

* docs(native-chat): the status-store listing rule names provider-journaled user messages

* fix(native-chat): a refused send notifies failed through the completion feed

The host's completion feed followed only the newest turn, so a send the
agent or its start refused, which creates no turn, read Failed on its row
but sent no notification. The feed now follows the session's latest
request, read from the projection the status feed already makes for the
commit: a turn keeps its id, a refused send is named by its journal item
key. It announces only while the session is idle, as the row reports a
verdict, so queued sends refused one commit at a time notify once, and a
withdrawn send falls back to a request already announced.

* fix(native-chat): every copy of a row carries the main agent's own status

History entries, sleep records and `worktree ps` rows carried a flattened
top-level `outcome`, copied under different gates and without the main agent's
clock. They now carry `mainAgent` (state, outcome, stateStartedAt), the type
the live row already persists and sends, and every copy site takes it with
`interrupted` through one function, `agentVerdictFields`.

- The accessor reads `mainAgent` then the legacy flag; the mobile mirror
  matches it line for line.
- Sleep records admit `mainAgent` with `normalizeMainAgentStatusField`, so a
  malformed value drops the field, never the record.
- Mobile dates a main agent that failed under live subagents by its own clock,
  as desktop does, and its row equality compares `mainAgent`.
- The activity feed reads a history entry's own `mainAgent` instead of
  rebuilding one; the sync key and history equality compare it.

* test(native-chat): pin the worktree ps verdict across host and phone versions

Pairs the real v1.4.212 host and phone row reader with this build: an old phone
reads a new host's rows by `interrupted`, a new phone reads an old host's rows
(no `mainAgent`) the same way, and a new phone reads a failure under live
subagents as Failed, dated by `mainAgent.stateStartedAt`. The release checkout
now carries the phone's self-contained row reader, and the lane runs when the
`worktree ps` row producers change.

* test(mobile): name the parity table's row for its role

* fix(native-chat): a request that settles while the user is asked something notifies once

The completion edge waited for an idle session, and a pending prompt (including a
subagent's approval) is not idle. Structured chat has no other attention producer,
so a main turn that finished while a subagent waited on the user sent nothing
until the prompt was answered.

The edge now waits only on owed work (a running turn or an unanswered send), which
the projection reports even beneath a pending prompt. A request that settles with
a prompt pending announces once; the renderer words it "needs input" from the
host status mirror's `attention`, and answering the prompt keeps the same request
identity, so it does not announce again. The wire shape is unchanged.

* fix(native-chat): the completion says when the user is being asked

A request that settles while a prompt waits on the user was worded "needs input"
from the renderer's status-feed mirror. Remote clients receive the status and
completion streams over separate sockets, so they can arrive in either order and
the wording could be wrong both ways.

The host already knows at emit time, so the completion now carries an optional
`awaitingUser: true` in that case and omits it otherwise. The renderer words the
notification from that field alone and no longer reads the status mirror. Old
clients ignore the field and word by outcome; old hosts never send it.

* fix(worktree-status): a departed agent's failure yields to live work on the worktree card

A retained failed agent has no expiry, so ranking it with a live failure pinned the card to Failed over other panes' live work. It now ranks below working, monitoring and permission, and above every finished outcome.

* docs(agent-status): a departed agent's failure ranks below live work on the worktree card

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(cross-version): load the phone row readers without mobile's toolchain

Vite transforms a file against its nearest tsconfig, and mobile/tsconfig.json
extends expo/tsconfig.base.json, which the root-only cross-version lane never
installs. The worktree ps verdict suite imported the current phone row reader
from mobile/ directly, so CI failed with TSConfckParseError before any test ran.

The harness now imports a copy of the working-tree reader placed under the
checkout cache, where the root tsconfig applies, as it already does for the
release checkout's copy. Both readers are still the real files.

* test(cross-version): keep the checkout path-guard message and justify the copy import's cast

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* fix(native-chat): a send the provider never received after a restart has no verdict

Restart reconciliation rejects a crash-stranded send that is absent from a
trustworthy provider history with reason 'not_delivered'. Nobody failed that
send, but the verdict allowlist did not name it, so after a crash the chat
read Failed, was listed, and could notify "failed". Give the reason a shared
constant (persisted value unchanged), add it to the no-verdict set, and treat
it as an internal marker so the Retry row no longer shows the raw string.

Jinwoo Hong c8f9a65ff8 test(e2e): keep the Kitty-arming app alive in the Option-composed spec (#23495)
The host grounds Kitty flags a finished command left armed, so a bare

cat foreground and pass per-test flags into setup instead of re-arming.

Brennan BensonandClaude bfe476f922 fix(native-chat): a message is accepted, then delivered (#22821)
* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the
proof write path and the unmounted UI. Keep agentSession.handoffStatus,
which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

* fix(native-chat): never let the pre-stop snapshot hold a chat's stop

Eviction now drains delivered events before quit's resume-offer snapshot. An
unbounded wait there sits ahead of the provider stop, so a sink whose journal
write stalls kept the child running until the step deadline aborted the
eviction. The offer is advisory: bound the drain and stop the child regardless.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(native-chat): drop helpers only the terminal handoff called

`claudeAuthEnvCarriedForward`, `isPathWithinDirectory` and
`queryWindowsProcessRowsFresh` lost their last caller with the handoff. The
fresh-scan tests now go through `queryWindowsProcessDescendants({ fresh: true })`,
the teardown path that still depends on that contract.

* docs(native-chat): stop citing the removed handoff in lifecycle comments

Six comments still named the handoff coordinator, a handoff suspend, or a
terminal-owned session as live participants in the flows they describe.

* test(native-chat): type the stalled snapshot drain without a cast

* test(native-chat): pin that a start dead before proving owes no settlement

The removed restart handoff test pinned this branch; nothing else did.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): keep the owner-status read behind an in-flight attach

The handoff removal dropped the per-session queue from `handoffStatus`, so a
read landing mid-start reported the reservation (no owner) instead of the
settled chat owner, and shipped desktop clients blocked worktree activation on
it. The read is queued again, as it was before the removal.

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(terminal): remove the agent-session PTY write gate

The gate only refused a write when a PTY had been bound to a chat session, and the
only code that ever bound one was the terminal handoff this branch removes. With it
gone, every admit/readmit returned "admitted" unconditionally, so the checks on the
renderer write path, the runtime controller backstop, terminal.send, agent prompts,
preview input and orchestration pointers, the refusal fields on terminal.send and
worker-start receipts, the plugin and CLI refusal copy, and the adopted-pane
orchestration routing could no longer run. Ordinary writes take the same path in
the same order as before.

* refactor(native-chat): drop the transcript helpers only the handoff called

appendLegacyTranscriptMessages fed the terminal transcript catch-up and
proveClaudeTranscriptBranch backed the terminal owner's exit proof. Both lost
their last caller with the handoff. Their tests now go through the live entry
points instead: the roster bounds through the legacy import, the pinned-read and
growth tests through the ancestry replay the history window uses, and the marker
rules through the string proof in their own file rather than the session-file
resolver's.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(native-chat): stop calling a starting chat "mid-handoff"

A send refused because the chat's owner is not settled showed "The session is
mid-handoff (<stage>)." in the composer. With the handoff gone, the stages that
reach it are a chat that is still starting, or one whose previous agent process
has not yet been confirmed stopped. The message now says which of the two it is.
The refusal code is unchanged.

* test(native-chat): type the stand-in roster decoder without a cast

Co-Authored-By: Claude <noreply@anthropic.com>

* refactor(codex): name the pinned rollout lookup for what it does

With the terminal handoff gone, the module named codex-tui-rollout-proof holds
only the pinned rollout lookup that structured Codex launches use to resume a
thread, so the name described code that no longer exists. Rename the module and
its options type. Also drop a mobile allowlist assertion that pinned the
removed agentSession.requestHandoff method, which no longer exists to allow.

* refactor(native-chat): type the owner-status reply as the host sends it

The handoffStatus reply type still listed the terminal handoff's fields and
states (terminal placement, host label, proof retry, queued and waiting phases,
the to-terminal direction). No host writes them any more and the only client
reader parses the reply as unknown, so they described nothing. The reply on the
wire is unchanged.

* refactor(native-chat): normalize terminal-handoff lease values once at decode

Nothing in this build writes a terminal owner (`runtimeKind: 'tui'`) or the
handoff's `preparing` / `old-owner-stopped` stages, but the in-memory types
still admitted them, so readers across the host kept branches for values no
path produces and the compiler could not point at them.

The store now validates the on-disk shape, which still accepts those values so
an older record is not quarantined, and maps them once while parsing:

- `preparing` and `old-owner-stopped` become `recovering`
- a `tui` lease becomes `native`; when it records a process it also becomes
  `conflicted`, the claim every build probes but never stops. A plain native
  owner would be stopped by restart recovery, here and in older builds.

Revisions are taken over the normalized state on both sides of every compare,
and the mapped record reaches disk with the store's first transaction, the
same way the tab-id backfill does.

The in-memory types narrow to what this build writes, and the branches that
existed only for the removed values go. Structured-worker identity keeps its
verdict for a former terminal owner by refusing a conflicted claim rather
than a non-native kind.

* refactor(native-chat): stop threading the owner kind through a reservation

A reservation only ever names a native owner now, so the request no longer
carries a kind and the reserved lease records `native` directly. The attach
params keep `runtimeKind`: agentSession.ensure and create accept it, and the
operation fingerprint stored in the ledger covers it.

* test(native-chat): pin the legacy-lease rewrite with a transaction that changes nothing else

Hiding a tab also committed the visibility index, so the no-op transaction
wrote the file even when its open-time revision was wrong. Committing the index
first leaves the pending rewrite as the only reason to write.

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

* test(native-chat): give the legacy-lease store test a tab id so the backfill cannot supply its rewrite

The seeded record had no surface tab id, so the next open backfilled one and
that rewrite alone made the no-op transaction write. The test passed with the
legacy-lease rewrite signal removed.

* test(worktree-activation): restore the OMP surfaced-agent resume test

The handoff removal deleted it alongside the terminal-owner tests, but it
covers the surfaced-PTY block that still guards resume, including an agent
whose ownership is unknown.

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

Brennan Benson 6c56c0a3dc fix(browser): a failed SSH route keeps its card while the host redials (#23465)
* fix(browser): a failed SSH route keeps its card while the host redials

A browser route that already failed swapped its "SSH connection unavailable"
card for "Connecting" on every dial of its host, and re-ran prepare once per
dial cycle, so the card flickered and its buttons detached mid-click. Only a
route that is still preparing now waits on a dialing host; a failed route
keeps its card until the host actually connects, which re-derives it.

Retry and Try anyway land on preparing together with the new attempt, so a
press while the host dials waits for the connect instead of starting a
prepare the effect immediately cancels.

The escape-hatch e2e now makes the host truly unreachable before the
disconnect; it passed before only because the card stayed latched over a
host the terminal had already reconnected.

* fix(browser): an unrouted SSH route waits for a dialing host too

Only a failed or ready route is exempt from the host wait; a route that just
became routed (or still shows another target's page) has no answer for this
target, so it must not start a prepare that its own preparing write cancels.

The escape-hatch spec now reads the settled failure from the renderer store:
main's ssh:getState drops the entry on disconnect and on a failed connect, so
its status is null there and never matches the failure pattern.

Jinwoo Hong 10807d8b45 test(e2e): stabilize terminal shortcut Kitty and Ctrl+C tests (#23472)
Shift+Enter: the host now grounds keyboard modes a finished command left
armed, so the test's one-shot `printf '\033[>1u'` was reset to 0 before the
poll. Keep the command alive via `read` while asserting, then let it pop
its own flags on Enter.

Ctrl+C: each test opens a fresh tab, and SIGINT during shell startup can
kill the shell and close the tab. Wait for a ready prompt before
interrupting. The existing post-interrupt assertions are unchanged.

Brennan Benson aeb96ab0e2 fix(native-chat): close only the reopened chat when main closes its tab (#22922)
After /clear the current chat keeps the window tab id derived from its first
session, so reopening that first session from history lands in a suffixed tab.
Main closed chat tabs in the window by re-deriving that id from the session,
which named the current chat instead of the reopened one: closing the reopened
tab (on the desktop or from a phone) also closed the current chat and stopped
its Claude.

Main now sends its own tab id, as it already does for every other tab kind, and
the window translates it through the host-to-window tab mapping it keeps for
mirrored chat tabs. The same translation lets a host-directed focus reach the
reopened tab. The close handoff marker is keyed on the id actually sent.

NeilandClaude 983250a12e fix: await queued Codex trust preflight completion (#23148)
* fix: await queued Codex trust preflight completion

* fix(agent-trust): bound the trust preflight wait and order the worktree-startup write

The awaited trust write had no cap. The local Codex writer queues on the
per-config.toml lane it shares with hook installs and app-server trust grants,
and the SSH writer chains a resolveHome round trip plus SFTP calls over a link
that may be half-open - so "start agent" could hang with no error. Cap the wait
at a single deadline and continue untrusted, which only loses the ordering
optimisation: the agent then raises its own trust prompt, so giving up fails
closed.

Also await the discarded write in worktree startup, where the PTY spawns Codex
on the next line and the synchronous catch could not see its rejection.

Update the reliability gate: its oracle asserted the absence of a deadline, and
its manifest was left unformatted.

* fix(reliability-gates): record the trust-preflight counts the cited command actually reports

The gate's evidence still described the pre-deadline suite: "32 author tests",
"New11pass", "original4fail/7pass". The four deadline tests this branch adds make
the cited command run 15 tests in `agent-trust-completion.unit.test.ts` and 36
across the four suites, so the manifest asserted counts its own command no longer
produces. Re-ran the command and recorded what it printed.

Re-ran the red/green as well, against the same 15-test suite rather than the 11 it
was first measured on. Pre-await: 5 fail/10 pass. Unbounded-await: 3 fail/12 pass,
where the fourth deadline test — the already-complete write settling on microtasks
— passes unbounded too, so it is a timer control and not a red; saying so beats
counting it as evidence for the cap.

Two claims the commit left stale: only the IPC handler is under test, yet the same
commit also bounds the worktree-startup write, and the cap is per call site while
three other awaited Codex trust writes are still unbounded. Both are now gaps
instead of silence.

OrcaWinandm4air 408499ec58 Keep SSH terminals parked after their own workspace updates (#23193)
* fix(ssh): suppress workspace echoes acknowledged during stale reads

* fix(ssh): preserve newer workspace observations during resync

* fix(ssh): retain newer own acknowledgements during stale reads

* fix(ssh): deliver peer snapshots cached by rejected patches during stale reads

A stale-revision patch reply caches the peer snapshot under a new host
observation token, but the renderer only records a conflict and blocks
uploads. Suppressing an identical stale read then left the peer change
unapplied. Only suppress when the intervening write kept the pre-read
token, which is what a contiguous own acknowledgement does.

Jinjing 0bad8b7490 Better add ai notes ui (#21719)
* feat(diff-comments): draft inline notes as editor view zones

Move comment drafting from floating popover to inline view zone. The draft card now appears in the editor flow, preventing overlap with code and integrating naturally with the diff layout. Includes styled margin indicator, auto-resizing textarea, and keyboard/submission handling.

* Preserve inline draft comments when switching diff views

- Reanchor draft zones to new models when file/line mapping changes
- Disable draft mode on large diffs to maintain performance
- Enhance draft card UX: shadow depth, outside-click handling, toast errors
- Carry draft body and position when reopening comments

* Ensure draft comment textarea auto-focuses and preserve drafts through e

- Focus textarea on mount via requestAnimationFrame for reliable focusing
- Add onDomNodeTop callback to focus textarea when zone reaches viewport
- Preserve pending draft when editor model refreshes and re-anchor on reload
- Add editor.getModel() checks before opening and re-anchoring drafts
- Test that textarea is focused on creation and errors are surfaced

* fix(diff-comments): prevent draft loss and duplicate submission on swap

- Track submission state to prevent carrying in-flight text to new cards
- Restore failed submissions for retry after model swap with unmount safety
- Use effects for proper ref management per React patterns
- Add isDraftOpen() guard to prevent re-opening the keyboard chord while composing
- Separate concerns between user clicks and draft-open state in decorator

* fix(diff-comments): show save error and restore focus intelligently

- Toast error when draft submission fails, so users see why it didn't save
- Return focus to editor only if the card still holds it when save completes, preventing focus theft on slow saves

* minor fix

* fix(diff-comments): park focus before submit button disables

Chromium moves focus to <body> when a focused button becomes
disabled, causing the draft zone to lose focus context. By
explicitly moving focus to the textarea before the button disables,
the zone can properly return focus to the editor after save.

* add all translation
