Jinjing e3de6b2ce8 Add automation runs dashboard with pagination and filtering (#18226)
* Add automation runs dashboard with pagination and filtering

Adds a new Runs view in the Automations page that lets users browse all runs across automations with status/host filtering, search, and pagination support. Includes virtualized table rendering for efficient handling of large run histories and summary cards showing 24h/7d success/failure counts.

* Fix missing dependencies in useCallback hooks and imports

Missing dependencies in useCallback can cause stale closure bugs. This
adds missing state setters to dependency arrays and consolidates type
imports for consistency.

* Use keyset pagination for stable automation runs pages

Pagination now uses createdAt:id boundaries instead of offsets, so new
runs arriving between pages don't shift the window. Maintains backwards
compatibility with legacy offset cursors.

Move pagination to shared module, fix outcome counting for future-dated
runs, and improve hook state tracking on authority re-pairing or target
changes.

* Extract automation run details to top-level page view

Moves run display from detail pane to dedicated page, establishing
three-level navigation (Automations → Runs → Run Details) and simplifying
the detail pane component.

* Fix pagination stability when automation runs share createdAt

- Define a stable total order with createdAt and id tiebreaker to prevent runs tied on createdAt from being dropped when the boundary run is pruned between page requests
- Retain cursor on failed pagination so pages remain retryable
- Update ownerNotice type to AutomationActionNotice

* Extract automations list panel and worktree map logic

Split AutomationsPageSurface into smaller, focused modules for better maintainability and reusability. Move list panel UI rendering to AutomationsPageListPanel component and worktree map selection logic to a standalone utility function.

* Add i18n strings for automation runs dashboard

Adds localized strings for the automation runs dashboard view, including search, filtering by host and status, run counts for 24h/7d windows, and empty state messaging across all supported languages.

* fix missing translation

Neil 8197268956 fix(pty,remote): close the pty master fd leak, and two remote-terminal defects (#17914)
* fix(pty,remote): close the pty master fd leak and two remote-terminal defects

so on Linux every later child of the process -- both later pty children and
plain child_process spawns -- inherits it and keeps the /dev/pts device alive.
Measured on Linux with stock node-pty 1.1.0: master fd flags 0404002
(cloexec=false), and 17 -> /dev/pts/ptmx present in both a later pty child's
/proc/self/fd and a later child_process child's. Extend the existing node-pty
patch with pty_cloexec() on both PtyFork spawn paths; after the patch the flags
read 02404002 (cloexec=true) and neither child sees the master. This covers the
app and terminal daemon only -- the SSH relay installs node-pty from npm on the
remote host, so it stays exposed (see the report).

rejecting inspection as a renderer-global unhandledrejection, which an
unreachable runtime produced on every cadence tick.

path cleared the close intent for it exactly like a dropped connection, so a
host that keeps republishing the dead surface re-materialized the pane the user
just closed. Keep that intent and drop its TTL. Also route the banner's
"Remote terminal was closed." line through translate() so it stops mixing
English into a localized banner.

* test(pty,remote): make the fd-leak evidence positive and size the close intent to its RPC

The Linux 'does not hand an earlier pty master to a later pty child' case only asserted that ptmx was absent from the captured listing, so any run that produced no listing passed without inspecting a single fd. Block the child on stdin, emit a sentinel, and assert both the sentinel and a real /dev/pts fd row before the negative assertion. Verified in node:24-bookworm: passes with the patch, and with pty_cloexec() reverted it fails on four inherited /dev/pts/ptmx rows.

The close intent's TTL was a 10s literal while the close RPC that can still answer tab_not_found had its own 15s literal. A host that answered slowly while republishing the surface had its intent evicted by the republish path's own pending-check, so makeWebSessionCloseIntentDurable found nothing to flip and #9194 reproduced. Derive the TTL from the shared session.tabs RPC timeout so the two cannot cross, with an invariant test and a regression test for the slow answer.

OrcaWinandOrca Worker c3c764fa03 docs(win): record why the PTY OSC 133 bootstrap keeps -EncodedCommand (#17875)
The MDE report lists src/main/daemon/shell-ready.ts as a contributing
"suspicious PowerShell" site and cites VS Code as using -Command. Measured
against a real VS Code fork install, VS Code's -Command payload is a one-liner
that dot-sources a *file*; that shape is execution-policy gated and is blocked
under Restricted and AllSigned, so it would silently drop OSC 133 -- and with
it foreground-process and exit-code tracking -- on the managed fleets MDE runs
on.

Inline -Command does carry the payload intact through node-pty/ConPTY
(powershell.exe 5.1 and pwsh 7.6.5), so the switch is feasible. It is declined
because no PTY site spells -ExecutionPolicy Bypass, AMSI and script-block
logging decode the payload either way, and the swap would put
$ExecutionContext.SessionState.LanguageMode, a Global:prompt override and
[char]27-assembled control sequences in clear text on every terminal's command
line -- higher-signal than the token it removes.

No behaviour change. Adds the rationale at the payload's source of truth,
one-line pointers at the three PTY launch sites, and a ratchet that both
launch builders must deliver the bootstrap byte for byte.

Jinwoo Hong a7fda48fe3 feat(telemetry): measure macOS stale-daemon adoption and cwd denials (#18043)
* feat(telemetry): measure macOS stale-daemon adoption and cwd denials

Adds two enum-only PostHog events so #17696 can be sized instead of guessed at:

- daemon_adopted: once per macOS launch that keeps a daemon an earlier app
  launch forked (invisible to daemon_lifecycle, which only sees replacements).
  Carries app-version match, spawner-path class (installed app / Squirrel
  ShipIt cache / other / missing), the existing TCC attribution verdict, and
  the bucketed live-session count.
- daemon_pty_cwd_denied: the symptom itself. The daemon probes the requested
  cwd in its own process (only its TCC context counts) and returns an additive
  cwdReadableByDaemon field; the app emits only when the daemon was denied AND
  the app can read the same path, so a missing or genuinely unreadable cwd
  never counts. Non-permission errors read as readable on purpose.

Both emitters swallow every failure; nothing here can delay or fail daemon
startup or a PTY spawn. Off macOS neither event fires. The new wire field is
optional, so older daemons and clients are unaffected.

* fix(telemetry): keep cwd-denial classification inside the swallow guard

Read the pid record at emit time (inside the try) rather than passing the
adapter's startup snapshot: a throwing app-environment read can no longer
escape spawn(), and a denial after a respawn is billed to the daemon that
actually spawned the PTY.

Neil 4efc86a33c feat(app): open Markdown files from the OS in the floating workspace (#17906)
* feat(app): open Markdown files from the OS in the floating workspace

Registers Orca as a Markdown handler on macOS, Windows and Linux, and opens
an OS-handed .md/.markdown/.mdx file as a floating-workspace editor tab —
the one editor surface that needs no project. Works cold-start and when
Orca is already running.

Main buffers the paths and both pushes to a live renderer and answers a
pull on renderer mount, mirroring SkillShareDeepLinkState. The buffer is
only released once delivery is possible: the renderer's pull is what proves
its ui:openMarkdownFiles listener is attached, because a push into a window
whose renderer has not subscribed is dropped by Electron with no error. Both
the push and the pull restore an undelivered batch, and a renderer reload
clears the latch so the fresh renderer re-proves itself. Paths are stat'd and
proven to be files before authorizeExternalPath sees them.

Windows association is registered by hand in the NSIS include rather than
through electron-builder's `fileAssociations`: app-builder-lib emits
APP_ASSOCIATE, whose first line overwrites Software\Classes\.md's default
value with no backup — silently taking .md from whichever editor owns it,
for every existing user on their next update — and APP_UNASSOCIATE never
restores it. The hand-rolled registration is additive (ProgID +
OpenWithProgids + SupportedTypes) and leaves the user's default alone;
verified end to end on a real Windows 11 host.

Closes #10138

* fix(os-open): register the new listener in the IPC inventory, and guard a non-array payload

CI caught two things the local run did not.

useIpcEvents-lifecycle.test.ts is an inventory of every App-lifetime IPC
listener and the exact order they register in; ui.onOpenMarkdownFiles now
appears there, positioned after the workspace-shortcut bridge's last
listener, which is where it actually registers.

Chasing that failure surfaced a real gap: the pending-open payload crosses
the preload boundary, so a stale or mismatched preload can resolve with
something that is not an array, and reading .length off it threw inside the
promise chain instead of failing at the boundary. Array.isArray now gates it,
with a regression test.

Jinwoo Hong 7873f73d80 fix(daemon): keep attach cancellation behind client timeout (#17816) 2026-09-01 17:52:43 -04:00
Jinjing 2b6c14d4b5 Add startup delivery diagnostics and success announcements (#17814)
Terminal sessions now report startup command delivery details (whether written, presence, length, and delivery method) without logging the command text—preventing credential leakage and distinguishing missing commands from lost ones in diagnostics.

Setup scripts now announce completion on both POSIX and Windows before executing the startup command, so healthy setups don't appear stuck in the UI with "Waiting for setup..." as the last visible line.

Diagnostics failures are caught and ignored so they never break session creation.

Neil ae35e044f2 fix(terminal): keep restored OSC-8 ranges across a no-op resize (#17759)
Cold restore seeded a checkpoint's OSC-8 link ranges and then replayed records
that resize, so any resize record after the checkpoint dropped them and
restored hyperlinks in scrollback lost clickability. Same-size resize records
reach the durable log routinely, because every attach re-asserts the pane's
dimensions and session-output-plane records each one without a same-size
dedupe — so an ordinary reattach was enough to lose the links.

Restored ranges are row-indexed, so clearing them on a reflow is right; a
resize to the size already applied is not a reflow. Gate on the dimensions
actually changing.

Introduced in d46349ce82 ("fix: improve mobile link modifier handling",
#5597), which added setRestoredOscLinks along with unconditional clearing in
both resize() and clearScrollback(). clearScrollback's clearing is correct and
is unchanged, with a test pinning it.

Found during adversarial review of #17752 and filed as #17756. Not a
regression from that PR: #17667 had incidentally masked it by gating no-op
resizes to protect a snapshot cache, and removing the cache removed the gate.
The same gate returns here on its own terms — as a correctness fix with tests,
rather than as a side effect of a cache.

Neil a5be10815c perf(terminal): drop the headless snapshot cache, keep the spawn lock (#17752)
Removes the snapshot memoization added in #17667 and everything that served
it: the epoch, markMutated/markWritten, the no-op resize gate, and the
HeadlessSnapshotCache module. The shared/exclusive spawn lock from the same PR
stays — it is the half that carries the measured win.

Why: a controlled A/B on merged main could not show the cache paying for its
memory. Same worktree, same sessions, reattach stable_adoption per session:

  cache + resize gate (as merged)   16 / 67 / 78 / 87 ms
  cache off, gate on                17 / 55 / 68 / 80 ms
  cache off, gate off               13 / 62 / 73 / 83 ms

Indistinguishable. Cold 4-tab activation was likewise unchanged (217-296ms
without the cache vs 226-309ms with), which is expected — a first attach is
always a miss.

The reason it under-delivers is a design fact the original PR missed: attach
does not request the full buffer. terminal-host-session-create.ts passes
resolveDaemonSessionScrollbackRows() — a deliberate 1000-row live window,
capped because unbounded retention once OOM-killed a host. Serializing 1000
rows is cheap, so there was little for a cache to save on that path.

Against that, the cache retained up to MAX_CACHED_SNAPSHOT_BYTES (4MB) per
entry across MAX_CACHED_SNAPSHOT_WINDOWS (2) entries per emulator, for the
session's lifetime, with no aggregate budget across sessions. It also carried
an invalidation contract that produced three separate over-invalidation bugs
during review (the parse fence, setCwd/setLastTitle, and the no-op resize).

The lock fix is unaffected and independently measured: the `options` phase,
which is pure queueing, went 0/125/212/291ms -> 1/1/1/1ms across a 4-tab
worktree activation and stays there.

Neil 4ca232c159 perf(terminal): cut cold worktree-switch attach latency (#17667)
* perf(terminal): let a worktree's terminal spawns run concurrently

The per-worktree terminal mutation guard was a FIFO mutex, so activating a
multi-tab worktree made each tab wait for every predecessor's whole spawn.
Measured with ORCA_PTY_SPAWN_TIMING=1 on a 4-tab worktree, the `options`
phase was a pure-queueing staircase: 0 / 125 / 212 / 291ms.

The invariant that guard protects is spawn-vs-sleep exclusion, never
spawn-vs-spawn. Replace it with a writer-preferring shared/exclusive lock:
spawns share, sleep still excludes, and a queued sleep blocks later spawns
so a stream of spawns cannot starve it into its 12s deadline.

Same worktree after: options = 2 / 3 / 12 / 34ms, and stable_adoption
flattens from 65/398/398/312ms to a steady ~253ms.

The existing folder-workspace control assertion asserted the FIFO behavior
this removes, so it is re-based on sleep-vs-spawn (which still queues) and
joined by a case asserting concurrent same-worktree spawns.

* perf(terminal): memoize the headless snapshot per mutation epoch

Attaching a viewer serializes the session's whole headless buffer
synchronously on the daemon event loop, so every reattach of a quiescent
session re-serialized identical bytes. Measured with ORCA_PTY_SPAWN_TIMING=1,
stable_adoption was 253-281ms per session on reattach.

Move snapshot assembly into HeadlessSnapshotCache and memoize its expensive
parts (the serialize, the OSC link walk, the frame-restore fields) on a
mutation epoch that every emulator state mutation bumps, so a cache hit is
byte-identical by construction rather than merely fresh-enough. The async
write path bumps on entry and again in the parse-completion callback, so a
snapshot taken mid-parse can never be retained.

Reattach of a quiescent session after: stable_adoption 12ms. Sessions with
output since their last snapshot re-serialize exactly as before.

Retention is capped: an entry is held for the session's lifetime once it goes
quiescent, and a renderer may request 50k scrollback rows, so oversized
payloads serve normally but are not retained. Cache hits clone nested values
so a caller mutating its snapshot cannot corrupt later ones.

* perf(terminal): keep the snapshot cache warm across zero-byte parse fences

Review follow-up. flushParsedWrites() is write(''), used purely as a parse
fence, and every getSettledSnapshot runs one — so the epoch bump on an empty
write evicted the attach entry on each checkpoint read, defeating the cache
for any session that gets checkpointed.

Zero bytes cannot mutate the buffer: the OSC and mouse-mode scans are no-ops
on '' and the partial-escape tail is idempotent, so skip the bump for empty
data. Real writes still bracket themselves, and any write a fence orders
behind has already bumped on its own completion.

Also invalidate on dispose, so a post-dispose read can never be served a
pre-dispose entry, and freeze the emulator's public method surface in a test:
the cache's correctness rests on every mutator calling markMutated(), which is
convention rather than a type, so a new method should be a deliberate decision
about invalidation instead of a silent stale-snapshot bug.

* refactor(terminal): apply elegance review to the attach-latency fixes

Reuse: waitForMutationGrant hand-rolled the deadline race that
settleBeforeDeadline (same directory, four existing callers) already owns.
Using it also picks up the timer.unref() the local copy lacked, which was
keeping the Node event loop alive for up to the 12s sleep deadline.

Simplify: drop the waiter `abandoned` flag. The timeout path sets it and
splices the waiter out in the same synchronous block, so no queued waiter can
ever be observed abandoned and both reads were unreachable. The splice is what
actually does the work; the comment now carries why that makes a
grant-after-timeout unrepresentable. drain() then collapses into its loop
condition and reuses markActive() instead of inlining it twice.

Extract markWritten() so the zero-byte parse-fence rationale lives at one
mutation gate instead of being restated at three call sites.

Match the daemon's byte-accounting convention: the retention cap is now
expressed in bytes with code-unit sizing, like MAX_COLD_RESTORE_CACHE_BYTES
next door, so the two retention budgets read in one unit. Same effective cap.

The public-surface guard test caught markWritten on the first run, which is
the behavior it was added for.

* perf(terminal): stop discarding the snapshot cache on non-memoized fields

Second elegance round, and it found the same class of bug as the parse-fence
one: cwd and lastTitle are read fresh on every build and were never memoized,
yet setCwd/setLastTitle bumped the epoch — discarding a whole serialize to
update a field the cache does not hold. OSC 7 cwd updates land on every `cd`,
so this was a live cost on exactly the busy sessions the cache targets. The
invariant is "every mutation of a memoized part", not "every state mutation";
both docblocks said the latter and are corrected.

Drop the dispose bump too. A post-dispose getSnapshot re-serializes the
disposed terminal to byte-identical content, so the bump bought nothing and
only reached into a disposed xterm — verified by probe, not assumed. Its test
asserted zero serializations after dispose, which no implementation could
violate; it passed with the bump deleted.

Also memoize rehydrateSequences (a string, so no clone needed) instead of
rebuilding it on every hit, derive the frameRestore type from
buildFrameRestoreSnapshotFields so a new field cannot flow through at runtime
while the type omits it, inline the single-caller resolve() into build(), and
move the write() entry bump after the sync early-return so the three bumps map
1:1 onto sync / async-pre-parse / async-post-parse.

The surface guard is sorted in source and renamed to say what it freezes: the
prototype, TS-private members included.

* fix(terminal): correct the fence justification and key the cache by window

The markWritten docblock claimed "zero bytes cannot mutate the buffer". That
is false, and I verified it: `_core.writeSync('')` drains xterm's pending queue
and applies it. The exemption is still correct, but for a different reason —
a fence cannot introduce an *unattributed* mutation, because any bytes it
drains belong to a queued async write whose own completion callback bumps
first. The two write regimes are exhaustive: with writeSync present nothing
can queue, without it every write is async and self-bumps. A comment asserting
a false invariant is worse than no comment, since the next change may rely on
it, so it now states the real one.

Key the cache by scrollback window instead of a single slot. Consumers ask for
different windows against the same emulator — attach passes the full window
while agent/text reads pass 0 — so one slot thrashed to a 0% hit rate whenever
they alternated, silently removing the benefit on runtime-side emulators. Two
entries cover every caller pair in the tree.

Drop the epoch counter: markMutated already nulls the retained entry and an
entry is only ever stored under the current epoch, so the comparison could
never fail. Invalidation is simply "clear the cache".

* refactor(terminal): name the lock sides shared/exclusive for a third caller

Rebasing onto main surfaced a semantic conflict the merge applied cleanly:
main added runWorktreeTerminalMutation (terminal orphan adoption, #17159) as a
third caller of the guard this PR changed. It needs the exclusive side —
adoption reconciles a worktree's terminal records, so it must not interleave
with a spawn registering a pty or with a sleep, which is exactly the semantics
it was written under when the guard was a plain mutex.

With three operations, naming the sides after two of them no longer fits, so
the kinds are now `shared` (spawn) and `exclusive` (sleep, adoption) — what
they do rather than who calls them.

* perf(terminal): do not invalidate the snapshot cache on a no-op resize

Re-measuring the final rebased build caught the cache barely working on the
path it exists for. Every attach re-asserts the pane's dimensions, and resize()
bumped unconditionally, so a reattach of a fully idle session missed its own
cached snapshot and re-serialized.

Measured on the same 4-tab worktree, reattach of sessions verified quiescent
(no buffer change over 4s), stable_adoption per session:

  before this commit:  98 / 382 / 395 / 418 ms
  after:               16 /  67 /  78 /  87 ms

A resize to the size already applied changes nothing the snapshot reads, so it
now returns early — which also stops it clearing restoredOscLinks, correct
since no rows shifted.

* fix(ci): size the Windows launcher-compile test budget from measurement

`native-smoke (windows-latest)` fails ~4.5% of runs on
`preserves a multiline argument through the compiled remote launcher`
with "Test timed out in 15000ms" — on unrelated PRs, for reasons that
have nothing to do with them. Across 176 sampled attempts it is the only
red that job produced, and it hit seven different PRs in two days:
#16900, #16904, #16915, #16955 (twice), #16979, #17014, #17085.

The test is six process creations: powershell.exe forks csc.exe, then
the freshly compiled orca.exe forks node.exe, twice. Hosted Windows
runners periodically slow process creation down, and this test amplifies
that far harder than anything else in the job. Comparing the 80 attempts
where it ran under 3s against the 12 where it ran over 12s, its own
median goes 2198ms -> 15917ms (7.2x) while the same file's
powershell-only test moves 556 -> 686ms (1.2x), the cmd.exe and Git Bash
process tests in the neighbouring file move 1.4x, and the other 35 files
put together move 1.5x.

Measured across those 176 attempts: 1881ms to 35438ms, p50 4264ms,
correlation +0.881 with the job's total Vitest duration. 8 of 176 (4.5%)
exceeded the 15s cap; 2 of 176 (1.1%) also exceeded the shared 30s
testTimeout, so deleting the override and inheriting the config is not
enough on its own. 60s clears all 176 with 1.7x headroom on the worst.

This is slow, not hung. Every body here is synchronous spawnSync, so
Vitest cannot interrupt one — the timer fires only after the body
returns and the reported duration is real elapsed time. That is why a
failure reads `× ... 22464ms` under `Test timed out in 15000ms`. The
work finished; the stopwatch was short. Seven reruns at one identical
head measured 2053 / 4680 / 5551 / 8732 / 13506 / 14868 / 21937ms — the
last of those would have been red on code that had not changed.

The 15s came from #8897, which raised this test off Vitest's built-in 5s
default because the job then ran bare `pnpm vitest run`. #8909 landed
3h27m later and pointed the job at config/vitest.config.ts, which is the
real fix for that. The constant stayed behind and has been the binding

Neil e17c98d425 fix(daemon): bound the whole boot-recovery sequence with one budget (STA-5732) (#17427)
* fix(daemon): bound the whole boot-recovery sequence with one budget (STA-5732)

* fix(daemon): keep socket probes inside recovery budget

* fix(daemon): size the recovery budget against the real post-kill tail

The 24s budget reserved only 9s for everything after the deadline, leaving
27s of the startup PTY gate's fail-open cap unused — and every unused second
is one where a daemon that would have drained gets killed with its live PTYs
instead. Reserve each post-deadline stage's actual hard cap (kill 10.5s, fork
10s, lease 5s) and spend the rest: 24s -> 32s of adopt window.

* fix(daemon): keep the last-resort endpoint rescue outside the recovery budget

The rescue probe in the launcher's outer catch was clamped to the recovery
budget's remainder, but it runs *after* that budget by construction — past
prepareDaemonReplacement, killStaleDaemon, the fork and the adoption lease.
The remainder is therefore essentially always negative, so Math.max(1, ...)
handed a live socket a 1ms connect window. On the loaded machine this path
exists for the probe loses to its own timer, the launcher rethrows, and a
recoverable degraded adoption becomes total daemon loss for the whole run —
the outcome the comment above it exists to prevent. Restore the 1s default
and pin the window with a test that drives the launcher to that catch with
the budget already spent.

Also make the deliberate narrowing legible instead of implicit:

- daemon-recovery-budget.ts: TRANSIENT_WEDGE_DRAIN_MS documented 20s as the
  grace #8697 sized, but #8697's merged second commit (840d3277d1) widened
  it to 11 retries ~= 60s. Record that 20s is the drain estimate and that the
  budget deliberately sits under #8697's shipped grace.
- daemon-init-wedged-daemon-grace.test.ts: pin the trade directly — a wedge
  draining after the budget is replaced and loses its live sessions.
- Rewrite 'preserves a daemon that stays wedged until the LAST allowed grace
  retry' onto the simulated clock. It never mocked Date.now, so its 12 probes
  elapsed ~0ms and asserted a retry grace the wall clock can no longer
  deliver; it now pins the last drain the budget still adopts.

* fix(daemon): name the socket probe default and correct the grace-retry rationale

Answers the review round on the budget accounting: the outer-catch endpoint
rescue is deliberately outside it, and the preflight clamp no longer duplicates
probeDaemonSocket's default as a bare literal.

Neil 70df6f0224 fix(terminal): mask the agent composer's dim placeholder during a preedit (#17377)
Split out of #17170, which now carries only the xterm composition-overlay work.

Codex and Claude draw an all-dim, full-row ghost placeholder. The opaque preedit
overlay reproduces the committed row tail it covers, so without this the ghost is
repeated to the right of the composing syllable instead of staying masked. The
binding keys off the `.xterm-composition-remainder` class that #17170 adds and
hides it through CSS while a composition owns a structurally verified placeholder
row — bold prompt glyph plus a dimmed model footer below a blank gap for Codex, a
frame line above the prompt for Claude. Arbitrary dim output, shell lookalikes,
and any row carrying typed text keep their tail visible.

readTerminalCursorLineContext moves from src/main/daemon to src/shared because the
renderer now needs the same reader the daemon uses; the move is import-only.

Depends on #17170.

Brennan Benson fd9125ea8c feat(native-chat): Codex structured native chat restructure (#16729)
* feat(native-chat): port structured Codex sessions from restructure-recovery

Rebuilds the desktop structured native-chat implementation from
brennanb2025/native-chat-restructure-recovery (tip 4e31c08db3) on top of
current main as a single commit, scoped to the local Codex path.

Ported:
- Structured agent-session core: durable record store + single-writer lease,
  canonical journal, agent-session wire host/attach/eviction/subscribers,
  `agentSession.*` RPC surface (registered via ALL_RPC_METHODS; host-side
  mobile allowlist included for wire compat), pty write gate, transcript
  additions, and the Codex app-server adapter/launch resolution.
- Renderer: NativeChatStructuredSession view/composer stack, structured
  launch path with the single-flight guard, local structured session tabs
  sync, activation gate + structured inventory (read-only
  `agentSession.handoffStatus` probe), agent-session tabs in the tab strip,
  AI-vault structured session activation, and the settings pane with the
  parent Experimental Chat UI toggle plus the nested "Use updated structured
  native chat" toggle. New sessions require both flags, agent codex, no
  prompt, and a local non-WSL, non-Windows-host execution host
  (structured-native-chat-availability).
- Fixes 72c013cea6 (verified Codex launch recovery), 8ddbaf5e3d (defer
  native terminal view switching affordances), and 4e31c08db3 (release the
  launch gate after a visibility retry) with their regression tests,
  including the third-launch-after-retry guard case.
- Cross-version agent-session wire test + CI lane, packaging entries
  (proper-lockfile, agent-tooling asar excludes), and the wire-compat doc
  section.

Deliberately not ported: mobile/ changes, the Claude structured runtime
(only the claude-transcript-branch-proof and claude-structured-owner-identity
leaf modules remain, backing the kept TUI-recovery arms), the terminal↔chat
adoption/handoff flow (`agentSession.adoptTerminal`/`requestHandoff`, the
handoff request engine, TUI adoption machinery, orca-runtime adoption
methods), renderer switching affordances and their dead leftovers, the
hook/subagent-status refactor cluster, and unrelated branch changes. The
crash-during-acquisition recovery path (restart handoff adjudication,
restore/reverse re-acquire, lease schema handoff keys) is kept because every
plain direct launch depends on it; a trimmed handoff coordinator exposes
only status/restore/close.

Branch edits that targeted files main has since split (ipc/pty.ts,
worktrees.ts, rpc/methods/terminal.ts, useIpcEvents, pty-connection,
store/slices/terminals.ts, runtime-types, web preload) were re-applied to
the split modules, preserving main's newer logic (Windows CIM fallback,
browser tab close rework, cold-restore resume flow, dispatcher threading).

Known seam: the mobile clipboard image-provenance CONSUMER gate ships
(agentSession.send refuses unproven mobile image refs with
agent_session_image_untrusted) but the producer hunk in
rpc/methods/clipboard.ts stays with the unported mobile cluster, so mobile
image sends into structured chat fail closed until that side ports.

* fix(native-chat): trust only authenticated local image uploads

* fix(build): preserve Windows process-tree patch application

* test(windows): include process creation time in addon fixture

* fix(build): run windows-process-tree node-gyp from the physical package dir

gyp expands the node-addon-api dependency by probing node, whose cwd
resolves to the package's physical directory in the store, so the emitted
target is a store-relative ../../../../node-addon-api@... hop. gyp then
resolves that hop against the rebuild cwd; from the node_modules
symlink/junction it escapes the store and configure fails with
"node_addon_api.gyp not found" (run 32999886072).

Rebuild from realpath(package dir) so both bases agree, matching how the
package manager itself runs native install scripts. The regression test
replays gyp's expansion+resolution against the planned cwd and fails
without the fix.

* fix(native-chat): keep chat tabs visible through terminal closes and empty-worktree launches

Two proven blockers in the native Codex tab contract:

closeTerminalTab pre-empted the canonical unified close. With one terminal
left it deactivated the worktree on a terminal/editor/browser-only check,
blanking a workspace that still held a renderable agent-session tab; with
two or more it pre-picked a successor from terminal entities only,
re-stamping the group active before closeUnifiedTab's MRU/neighbor repair
could land on the chat tab. Successor choice now defers to the unified
contract whenever the terminal has a unified row, and deactivation is
gated on the unified renderable count (matching leaveWorktreeIfEmpty),
with the legacy pre-pick kept only for terminals without a unified row.

A structured session created on an empty worktree was published into the
host's headless group while preserveLocalLayout froze the local layout,
leaving the tab in store but permanently off screen. A preserveLocalLayout
owner now always takes client-owned placement — repairing a rendered
leaf whose group record is missing, or materializing a rendered group on a
truly empty worktree — and applies the client-derived layout repair while
still rejecting host-authored layout.

Regression tests drive the real store through closeTerminalTab (git
worktree and folder workspace) and the real snapshot applier for the
empty-worktree adoption states; all fail without the fixes.

* fix(native-chat): anchor an unmatched chat echo where it was sent (#16117)

* fix(native-chat): anchor an unmatched chat echo where it was sent

The reported symptom was old user messages replaying below every new turn, so the
conversation read as scrambled. The cause was not that the echo failed to match a
transcript row. Claude consumes a mid-turn send through a `queued_command`
attachment and writes no `type:"user"` record for it, so some echoes can never
match, and no amount of matching will change that. The cause was WHERE an
unmatched echo rendered: buildMobileNativeChatTransientData appended every pending
item after the entire transcript, so it re-read below each turn that landed
afterwards.

Render each echo directly after the transcript row it was sent against, using the
baseline the send already captures. An unmatched echo is then at worst a duplicate
in the right position rather than a scrambled one, and it stays visible. Echoes
sharing an anchor keep send order; a send with no baseline, or one whose anchor
folding dropped, still falls back to the tail.

Deliberately NOT fixed by deleting the echo. Inferring from send ordering that an
echo can never match, then removing it, loses the user's own text for a message
the agent did receive, and it cannot fire in the common case anyway - measured
drain groups are 1,017 of size 1 against 55 larger. It also escalates an existing
gap: the count pass has no baseline-tail guard, unlike the glue pass, while
`messages` is a 40-row window that head-trims, resets on reconnect and grows at
the front on loadEarlier, so a false landing there would license deleting a
DIFFERENT outstanding message.

That count-pass gap is real and left for a separate change; anchoring makes its
worst case a duplicate in place rather than a scrambled conversation.

* fix(native-chat): preserve folded echo anchors

* fix(native-chat): preserve forward-folded echo anchors

* fix(native-chat): keep leading folded echoes in place

* fix(workspace-cleanup): show git status for every row (#16690)

* fix(native-chat): refuse structured chat on every Windows execution path

canUseStructuredNativeChat only refused win32 when a project runtime
resolved, so folder-workspace keys (and other keys with no project
runtime) failed open into structured chat on Windows. Fail closed on
win32 unconditionally after the host check, matching the settings copy:
local macOS/Linux only; Windows/WSL/SSH stay on terminal chat.

* fix(native-chat): restore runtime refusals behind the win32 gate

506d375de3 replaced the project-runtime checks with a bare platform test,
so a WSL or repair-required runtime resolution would no longer refuse
structured chat off-win32. Keep the unconditional win32 refusal and
re-run the runtime resolution after it, so the gate does not depend on
the resolver's own platform guard. Tests inject WSL and repair-required
resolutions on darwin/linux and fail against the regressed gate.

The switch effect adjusted error state after the sessionId prop changed,
tripping react-doctor's no-adjust-state-on-prop-change on the changed-code
gate and flashing the old session's banner for a frame. Reset it with the
render-time previous-value guard instead.

* fix(native-chat): invalidate stale outbox settlements

* test(native-chat): restore settled-error session-switch regression

a6e2379bd1 replaced this test with the in-flight settlement race test,
leaving the render-time error reset unpinned: deleting the reset block
still passed the whole native-chat suite. Keep both scenarios pinned;
they are distinct (settled error clears on switch vs stale settlement
invalidated in the commit-to-passive window).

* test(wire): make release checkouts race safe

* test(wire): pin cross-process checkout single-flight and importer specifier contract

* test(wire): harden release checkout lifecycle

* fix(build): drop CR-byte residue from windows-process-tree patch

The two trailing CR bytes on the patch's deletion lines are a proven
no-op: pnpm hashes patches CRLF-normalized (both forms hash to the
lockfile's 946ffb2b) and materializes this package without applying the
patch in either form, so the load-bearing build edits come solely from
applyWindowsProcessTreeBuildFixes() (#16947), which handles both source
EOL forms. Restore byte-identity with main and repin the contract test
to the post-#16947 reality: LF-only patch bytes plus lockfile hash sync.

* fix(native-chat): skip empty startup recovery

Brennan BensonandBrennan Benson 7abdf037d6 Fix Windows daemon host pruning on unverifiable liveness (#16908)
* Fix Windows daemon host prune liveness contract

* Scope host prune evidence per version

* Drop redundant default cases from exhaustive liveness switches

All three switches consume ProcessLivenessVerdict/ProcessSignalEvidence values
constructed in-process by inspectProcessSignal/inspectProcessLiveness; the union
is never deserialized from a wire, RPC, or persisted record, so the defaults are
genuinely unreachable.

* Cover prune liveness gates and quarantine corrupt pid records

* Make the prune delete-gate fail safe and refuse truncated pid salvage

The prune switch shared #16900's delete-gate shape: an unhandled future
verdict status fell through into rmSync, protected only by the lint
exhaustiveness rule. Deletion is now opted into by a positively matched
'exited' via reclaimUnownedDaemonHostDir; a pinning test feeds an
out-of-contract verdict and asserts the host dir survives.

Pid salvage from corrupt records now requires the digit run to be
terminated by a following non-digit byte. A tear inside the digits leaves
a truncated prefix that is a different pid: probing it either quarantined
a record on an unrelated process's death or, when the prefix collided
with an immortal pid (Windows System pid 4), re-created the permanent
prune veto for that record. Unterminated digits mean the writer died
mid-write, so the record quarantines without consulting any probe.

* fix(daemon): stop an in-flight pid publish from being read as a dead version

publishDaemonPidFile creates the record before writing it (writeFileSync with
flag 'wx'), so a concurrent launch can read a live daemon's record as empty. A
two-process probe observed the empty window on 7 of 2273 reads.

An empty record was not treated as corrupt at all: the parser's legacy
bare-integer fallback coerces it to pid 0 (Number('') === 0) with appVersion
null, so the scan skipped it as a pre-relocation daemon, left its version
unpinned, and the prune reclaimed a running daemon's host image -- the exact
destructive outcome this change exists to prevent, reached without any
'unverifiable' verdict. A pid that is not a positive integer names no process
(process.kill(0, 0) probes the caller's own process group), so it is now a
veto rather than a skip.

Quarantine additionally refuses any record written in the last minute: an
in-flight publish is by definition fresh, while a record left corrupt by a
dead writer ages past the floor and is quarantined on a later launch. Fixed
locally rather than in parseDaemonPidFile, whose null result also drives an
unlink in daemon-stale-kill.

Each gate is pinned by a test that fails individually when it is reverted.

Neil 64f537f442 test(terminal): pin that Hangul is two cells under every unicode provider (#15477)
* test(terminal): pin that Hangul is two cells under every unicode provider

#15192 turned out to be an upstream Antigravity CLI defect, but the
investigation re-litigated Orca's Hangul cell width three separate times
before ruling it out. This makes that negative result durable.

The first test closes a real gap rather than restating the others. Nothing
verified which provider actually ends up active in production:
pane-lifecycle.test.ts asserts activeVersion=11, but its terminal mock has no
_core, so activateOrcaTerminalUnicodeProvider can only ever take the fallback
branch there. This asserts on a real terminal, in pane-lifecycle's order, that
the Orca provider is reached.

The sweep matters because it is what makes the width theory unavailable
rather than merely unproven: all 11,172 precomposed syllables budget two
cells under v6, v11 and the Orca provider, against both wcwidth and the
packed charProperties bits. Even total activation failure leaves them wide.

Also pins the wide-cell test oracle's disagreement with xterm on conjoining
jamo U+1160..U+11FF. Only decomposed Korean reaches them and no fixture
writes NFD today, so nothing mis-asserts now - but a repaint test would
silently assert against a wrong oracle if anyone added NFD text.

Refs #15192

* test(terminal): drop the version-sensitivity list as redundant

Its output is a strict subset of the oracle-divergence test's, measured a
different way, for about one bit of information across twenty lines.

Refs #15192

* test(terminal): assert both widths in the Hangul oracle divergence, drop the pane-lifecycle-order claim

The oracle divergence only asserted that xterm and the fixture disagree, not how:
widening the fixture's jamo range from one cell to two left the expected list
byte-identical, so the tripwire it exists to be would not have fired. Record both
widths in the run key.

Test 1 claimed to pin pane-lifecycle's activation order, but it mirrors that order
rather than importing it — deleting the call at pane-lifecycle.ts:88 or moving it
before loadAddon leaves it green (pane-lifecycle.test.ts covers both). Retitled to
what it does pin: that xterm's live _core shape still reaches the non-fallback branch.

Neil 5631aa00dd feat(orcad): items 2–7 — degradation, natives, daemon, ops, deploy (#16398)
* fix(ports): stop joining an undefined resourcesPath on a non-Electron host

`resolveWorkerEntryPath` branched on `isPackaged` alone and joined
`process.resourcesPath`. orcad reports `isPackaged` true — correctly, it is a
production build, and ~15 consumers read it that way to gate HTTPS-only skill
downloads and the real CLI name — but `process.resourcesPath` is Electron-only
and `undefined` under plain Node.

So the packaged branch threw
`TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string`
where a clean "worker unavailable" was the honest outcome. The type said
`resourcesPath: string`, which is how it went unnoticed; it is now
`string | undefined`, so the compiler carries the fact.

A host with no Electron resources tree has no asar to look in, so it falls back
to the module directory and lets the caller report a missing worker.

Found by the item 1 agent while auditing the same `isPackaged` defect class in
the watcher. Verified in both directions: reverting the guard reproduces the
TypeError.

* feat(orcad): prove node-pty loads before anything requires it

Of the two ways node-pty fails, only one is catchable. A missing module throws
MODULE_NOT_FOUND. A module built against the wrong libc or Node ABI is refused by
the dynamic loader, and in the worst case takes the process down before any handler
exists — that is #9902, which crashed the desktop app on Ubuntu 20.04 before a
window appeared. There was no libc or ABI precondition anywhere in the tree.

So orcad now proves the load in a CHILD process, from main.ts, before anything
requires node-pty. Whatever the child does — throw, abort, die on a signal — is data
rather than our own death, and the operator gets a sentence naming the host's libc,
Node ABI and prebuild slot plus the command to run. Proven-unloadable exits 78
(EX_CONFIG), so a supervisor does not restart an unequippable host forever. A probe
that never answered is unverifiable, not blocked: refusing to boot on an inconclusive
signal would take down hosts that work.

The child dlopens the file node-pty would have chosen, before requiring the package.
node-pty's loader walks several directories and rethrows only the LAST error, so a
refused binary reads as "Cannot find module ./prebuilds/..." — which sends the
operator to install a module that is already there. It also reports through stdout:
node echoes the whole -e source above a stack trace, and matching tokens against
stderr made the probe's own source text answer for the verdict.

Verdicts reach clients as a terminal_unavailable degradation alongside the existing
browser_unavailable one, through the same cause-registry shape. degradations[].code
is now an open vocabulary; clients already render only `message`.

Prebuilds are compiled from PATCHED sources — the patch IS the glibc-floor fix, so an
upstream tarball reproduces #9902 — into linux-{x64,arm64}-{glibc,musl} and
darwin-{x64,arm64} slots. libc is in the slot name because node-pty's loader falls
back to prebuilds/<platform>-<arch> and cannot tell glibc from musl. orcad installs
the matching slot at boot, so a host with no compiler serves terminals.

The relay's five pure toolchain-diagnosis functions moved to a transport-free module
so the Node bundle can reuse them without dragging ssh2 in behind them; the relay
keeps its API by re-export. macOS gets `xcode-select --install` rather than the
cross-distro apt/dnf/pacman/apk menu, every line of which is wrong there.

* test(orcad): pin the node-pty precondition to ground truth, not a prepared host

CI's test shard runs `vitest` directly, so `ensure-native-runtime --runtime=node`
never prepares node-pty for the Node ABI — `degraded` is the correct verdict
there, and asserting 'ok' encoded an environment the shard does not have.

Asserting whatever it returned would be vacuous, so the expectation is now
derived from an independent require() of node-pty. Verified it still bites:
forcing the precondition to always report 'ok' fails the suite.

* feat(orcad): run the terminal daemon, and the ops contract around it

orcad declared `canRecoverPersistentLocalPtys: () => false` because it did not
run the terminal daemon, so every restart, update and rollback SIGKILLed every
running terminal — on the host whose selling point is that work survives the
client going away. That is the one property `ssh-execution-boundary.md`
recommends the peer model for.

Item 4 — the daemon:

- Port the launch path off electron: `daemon-init.ts`,
  `daemon-host-relocation.ts` and `observability/logs-directory.ts` now read
  the `AppEnvironment` port. Relocation additionally asks whether the app root
  is an asar archive rather than whether the build is packaged, so a Node host
  answering `isPackaged() === true` no longer walks into an Electron-only
  NSIS-escape path (same precedent as `parcel-watcher-entry-path.ts`).
- `build-orcad.mjs` emits `daemon-entry.js` beside `orcad.js`, scans the
  forked children's metafiles for electron/node:sqlite, and load-checks the
  child under plain Node.
- orcad spawns and adopts the daemon; shutdown disconnects and never kills it.
  `canRecoverPersistentLocalPtys` now reads the live provider and is false
  under degraded routing, where fresh terminals would die with the process.

Item 3 — the ops contract (docs/reference/orcad-operations.md):

- Bind policy: `--bind`, default loopback, pinned so neither `orca serve`'s
  wide default nor the connected-device widen can override it, and so a paired
  client cannot rebind the listener from outside.
- Instance lock on the data root before profile load, scoped to the runtime
  role so it never refuses a restart that a live daemon makes worthwhile.
- Supervision: exit codes a supervisor can act on (78 = do not retry),
  second-signal escalation, a shutdown deadline, and crash-loop containment on
  daemon respawn.
- Health in the readiness payload: build hash, Node ABI, and a PTY self-test
  that spans both processes — the daemon spawns a real PTY in its own process
  and the verdict crosses its socket.

Both bundle load-checks now assert on exit codes: these bundles are minified
onto one line, so Node's uncaught-exception report echoes every string literal
in the bundle and the previous message match passed against a bundle that
never loaded.

* feat(orcad): deploy, activate and roll back a versioned orcad install

Plan items 6 and 7 from docs/design/shipping-orcad.html.

Install reuses the relay's transaction verbatim — per-version lock, staged
SFTP write, .install-complete sentinel, stale-lock recovery — under a
parameterized namespace, so orcad-<v>/ sits beside relay-<v>/ permanently
(§06). Parameterizing GC is the trap that creates: each model now collects
only its own directories, enforced twice (prefix-scoped remote listing plus
a local ownership re-check), and a client picks its model from how the host
is registered, never from what it finds on disk.

Activation is separate from installation, because a versioned directory
selects nothing. A candidate is launched, publishes orca_server_ready, and
only becomes active if its cross-process health payload passes: right build
hash, listening, daemon live, PTY self-test green. A rejected candidate is
stopped and the incumbent restarted, so a careful deploy cannot cause the
outage it was being careful about.

Update and rollback are shaped by the daemon. An update restarts orcad, the
daemon outlives it, and the surviving daemon was forked from the outgoing
bundle — so live terminals defer the update rather than proceed, and GC pins
the active version, the rollback target and the live daemon's bundle. Orca's
persisted state carries no schema version, so rollback restores a
pre-activation snapshot rather than trusting backward-readability; the point
past which it is unsafe is the first terminal created after activation,
which the snapshot cannot describe and the surviving daemon still owns.

Running the generated shell for real found two bugs the text assertions
missed: tar members re-quoted inside a shell variable captured nothing, and
kill -0 reports a zombie as alive.

* test(orcad): assert the precondition is self-consistent, not environment-shaped

The real-host case cannot predict a status: CI's shard runs vitest directly, so
node-pty is never built for the Node ABI and 'degraded' is correct there, while a
prepared checkout gives 'ok'.

The previous attempt used require('node-pty') as ground truth, which resolves the
JS wrapper while the native binding loads lazily — it proved strictly less than
the precondition checks, and failed CI for exactly that reason.

What is invariant on a host with node-pty installed: never 'blocked', and never a
degraded verdict carrying an unestablished reason. The injected-input tests keep
the logic coverage.

* fix(orcad): drop an eslint-disable the rule no longer needs

* test(orcad): separate slot placement from the load verdict

Both remaining CI failures were the same shape: tests reaching into node_modules
for a pty.node that only exists after `ensure-native-runtime --runtime=node`,
which CI's shard never runs because it invokes vitest directly.

Slot *placement* is the logic worth checking on every host, so it now uses a
synthetic payload and asserts the verdict stays honest about not loading. The
three assertions that genuinely need a Node-ABI binding are gated on it existing.

Verified: breaking slot installation fails both placement tests; with the real
pty.node hidden the file is 17 passed / 3 skipped instead of ENOENT.

* test(orcad): gate the load-dependent cases on a real load, not on the file existing

CI ships a pty.node built for Electron's ABI, so existsSync was true while require
still failed — the gate ran exactly the tests that host can never satisfy. It now
probes the binding in a child process, so a bad one cannot take the runner down.

The self-consistency assertion also allowed too little: 'blocked' is the honest
verdict for a corrupt binding, alongside 'ok' on a prepared host and 'degraded' on
an unprepared one. What stays invariant is that anything other than 'ok' names an
established cause, so a terminal is never declined for a reason nobody worked out.

Verified against all three host states: prepared (19 passed), unprepared, and a
corrupt binding (17 passed / 3 skipped, no failures).

* test(orcad): gate on the whole premise — binding AND spawn-helper

CI has a loadable pty.node but no spawn-helper, and a slot without the helper is
legitimately 'degraded'. So the previous gate let a test run whose premise ('a
complete slot yields ok') that host cannot satisfy.

Verified in both states: with the helper present 19 pass; with it removed the
load-dependent cases skip (17 passed / 3 skipped) instead of failing.

Neil 5e900b10b3 fix(windows): let a build with no job exports still retire a dead agent (#16563)
* fix(windows): let a build with no job exports still retire a dead agent

#16419 (a1ec0479e2) routed the foreground poll's liveness question to the job
object. On a build whose node-pty lacks the job exports the read returns null,
which judgeCachedAgentJobEvidence reports as 'unavailable' -- correctly refusing
to treat loss of contact as death. But that is the wrong reading here, and it
matters more than it looks:

**every shipped Windows release is such a build.** The patch adding
listJobProcessIds is in no v1.4.* tag, 1.4.188 included (#16059). So for every
Windows user today the read is null on every poll, the verdict is always
'unavailable', and the retire path never fires at all. Their panes keep a dead
agent's name indefinitely, and because a non-null cache makes idleNoEvidenceShell
false, the refresh also stays pinned at the 1s TTL instead of backing off to 15s.

That is worse than what #16419 replaced: the forked probe was expensive but it
did retire.

The distinction the verdict was missing is between "we could have asked and could
not" and "there is nothing to ask". Only the first is unverifiable. A build with
no job exports is the second, so it now returns 'unsupported' and the
authoritative scan decides alone -- exactly as it already does off Windows.

Deliberately NOT falling back to the forked console probe: that is the #10857
storm this whole path exists to avoid, and re-forking per poll for the entire
current fleet would be the worse trade. The scan that reaches this branch has
already reported available and found no agent; trusting it needs no fork.

Also deliberately not age-based: an earlier draft retired on age alone, which
would expire a LIVE agent that a scan could have confirmed, since 'unproven'
short-circuits the scan.

isWindowsPtyJobReadable() sits beside the read rather than being imported from
windows-pty-job, so one module mock controls both facts. Without that, every
Windows-simulating test on a macOS runner silently took the unsupported path,
because isPtyJobOwnershipAvailable() is false off Windows -- the suite would have
been testing a configuration no Windows user has.

* test: give every job-membership mock the readability export

Nine of the nineteen files mocking windows-pty-job-membership supplied only
readWindowsPtyJobProcessIds, so isWindowsPtyJobReadable resolved to undefined in
those suites. They pass today only because none of them reaches the call; the
first one that does gets 'isWindowsPtyJobReadable is not a function'.

Left alone this is the same trap the export exists to prevent -- a suite that is
green about a configuration no user runs -- just arriving as a crash instead of a
wrong answer. All nineteen now declare which build they simulate.

Neil a1ec0479e2 fix(windows): revalidate PTY liveness from the job object, not a forked helper (#16419)
* fix(windows): answer console membership from the job object, not a forked helper

node-pty answers "which processes are attached to this pane's console?" by
FORKING a helper, because GetConsoleProcessList must run from a process
attached to that console. Orca asked on a foreground poll, per pane, so each
read spawned a conpty_console_list_agent -- hundreds of hidden processes
exhausting RAM within minutes, respawning as fast as they were killed (#10857).

QueryInformationJobObject has no console-attachment constraint: any process
holding the job handle can ask. Orca already creates that job per PTY, and
listPtyJobProcessIds has exposed it since the W1/W2 work with zero callers.
One syscall, no children.

Semantics the three call sites rely on are preserved: a root-only set still
proves the shell is alone (so a stale agent can be retired), and size > 1 still
proves something is running under it. The single difference is that a
descendant detached from the console stays in the job -- which widens the set,
the conservative direction for every caller.

Also fixes the third call site, which returned { available: false } whenever
membership was unavailable AND a recognized agent existed -- i.e. exactly while
an agent was running. Membership only ever narrowed the candidate list, so an
unavailable answer now leaves it unfiltered instead of failing the whole
resolution.

The no-fork test is asserted through a module-level vi.mock of
node:child_process. A vi.spyOn of a require()'d child_process does not
intercept the module's own import binding: the first version of that test
passed with a fork() deliberately reintroduced.

* fix(windows): keep console attachment for the candidate filter

Readiness review caught that this PR changed two different questions as if they
were one, and the repo's own plan doc had already said so:

  "The job is the wrong set here -- it would re-admit precisely the detached
   process the filter exists to drop."  (windows-wsl-root-cause-plan.html, Use B)

The two uses:

- Use A, `size > 1` at local-pty-provider and the daemon tracker -- "is anything
  in this pane besides the shell?". The job answers this, in-process and with no
  fork. Unchanged from the previous commit.
- Use B, the candidate filter -- "which of these are ATTACHED TO THIS CONSOLE?".
  Its whole job is dropping a descendant that detached, and the job object keeps
  those, so answering it from the job makes the filter a no-op in its motivating
  case: a detached `Start-Process droid` would be granted byte authority, and a
  detached sibling would make an attached agent look ambiguous.

Use B goes back to GetConsoleProcessList, in its own module named for what it
answers, with its fail-closed null restored. That path is not the #10857 storm:
it runs only when a recognized agent candidate already exists, not on every
foreground poll. Bounding it to one pooled supervised helper is the remaining
half, and per the plan doc either half alone takes #10857 from unbounded to one.

My earlier claim that widening membership is "the conservative direction for
every caller" was wrong -- true for Use A, backwards for Use B. The hardware run
did not catch it because I measured a WSL pane, where the superset is harmless,
and never a detached GUI child, which is the divergence.

* fix: restore the coverage and ratchets the module split dropped

Round 2 of review. Two blockers, both from moving the forking code to a new
file without moving what guarded it.

- The child_process import ratchet was RED: windows-console-attached-processes.ts
  imports node:child_process and was unlisted, and the old entry was stale. I
  never ran that suite -- lint and the providers/daemon tests both pass without
  it, which is exactly the gap the ratchet exists to close. Entry repointed;
  count unchanged at 159.
- The forking module had ZERO tests. Its 11 assertions -- bounded timeout,
  single kill, spawn error, malformed message, helper-pid removal -- were in the
  file that now answers a different question, so the module that actually caused
  #10857 was shipping untested. Moved with the code.

Also: nothing pinned the round-1 fix itself. No test drove console attachment to
null and asserted the fail-closed result, so re-deleting that branch would have
gone green. Now covered, and verified to fail when the branch is removed.

Cleanups the split left behind: `consoleMembershipUnavailable`/`consoleProcessIds`
renamed to `pane*` where they now hold job membership, the duplicated
`WindowsConptyMembershipDeps` type name, comments still describing the console
on the job path, and eight reliability-gate paths pointing at the moved tests.

* fix(windows): let a superset job answer expire instead of vetoing retirement

Round 3. The job read had reintroduced #9258's bug by a new mechanism.

`size > 1` returned unconditionally, so any pane holding a console-detached
descendant never retired its cached agent. A WSL pane always holds some: the
measurement in this PR's own test recorded job [40980,104068,4888,69908] against
console [69908,40980], i.e. console said "shell alone, retire" while the job said
"three others alive, keep". #9258's third commit describes the identical failure
from the other direction -- a bare shell reading as [helper, shell] "looked like
it still had a child ... the foreground refresh held the exited agent's identity
indefinitely" -- and that is what came back.

It bites because the read branch that serves the cached name across a Windows
shell fallback is deliberately untimed: #9258 made it so on the stated assumption
that "the background refresh authoritatively retires it". Removing the retire
authority left the identity with no bound at all. Second-order: a non-null cache
makes idleNoEvidenceShell false, which pins the refresh at the 1s TTL, so an idle
WSL pane also scanned the process table every second forever.

A TTL on the read would have been the wrong fix -- untimed is deliberate, because
on Windows the fallback name is structurally uninformative. Instead the job answer
is treated as what it is: a SUPERSET of the console, which cannot tell a working
agent from a leftover. Proof of absence retires immediately (size 1, unchanged);
an inconclusive answer ages out at 30s; unverifiable (null) still holds forever
per ssh-execution-boundary.md. Only successful scans that found no agent advance
the clock -- a degraded scan returns before this -- so the fix cannot expire an
agent it simply failed to see.

Also from review:
- Restore the root requirement the forked probe had. Without it a set of one
  non-root pid -- shell gone, descendant alive -- read as "shell alone, retire",
  inverting the truth.
- Rename to windows-pty-job-membership.ts / readWindowsPtyJobProcessIds. The old
  name still said ConPTY console while reading the job, and conflating those two
  sets is precisely the bug aee07c24aa reverted. Same for
  windows-console-foreground.ts, which guards a job read now.
- Gate the two files that had no coverage: the job read and the retire path.

* fix(windows): bound the provider's job short-circuit too

The previous commit fixed the daemon retire path and left the identical bug in
the local provider, which I found while asking the reviewer to check for it.

local-pty-provider.ts returned the cached agent early on `size > 1` and that
early return skips the scan at the bottom of getForegroundProcess -- the ONLY
code that can delete ptyLastRecognizedForeground. So on a WSL pane, whose job
always holds console-detached plumbing, the short-circuit was permanent and the
identity could never be cleared. Same failure, second location, and the daemon
fix did nothing for it because this path never calls retireStaleForegroundIdentity.

The cache was a bare Map<id, name> with no timestamp, so bounding it needs one.
Added ptyLastRecognizedForegroundAt, stamped only when the recognized name
actually changes, and paired with every existing delete including pane teardown
so the new map cannot outlive the old one.

The 30s threshold now lives in windows-cached-agent-revalidation.ts rather than
being duplicated: that module already answers "can we revalidate this cached
agent without a scan", and the max age is the other half of that question.

Also renamed two tests that still said "ConPTY console presence" while driving a
job read. Re-conflating those two sets by name is how this PR got its first two
review rounds wrong.

* fix(windows): stamp the provider cache on every confirmation, not on change

My own previous commit was wrong, and wrong in the direction #9258 exists to
prevent. Review caught it; the test in this commit reproduces it first.

I stamped ptyLastRecognizedForegroundAt only when the recognized name CHANGED.
That makes the value the time of first recognition, so the age measures how long
the agent has been running rather than how long since we last confirmed it. For
a live agent recognized as the same name every cycle the stamp never moved, the
age crossed 30s and stayed there, and the short-circuit died permanently.

Two consequences, the second serious:
- every getForegroundProcess call on a >30s-old agent pane ran the whole-table
  scan, defeating the exact optimization the branch exists for;
- with the short-circuit off, one available-but-agentless snapshot was enough to
  delete a LIVE agent's identity, because paneMembershipUnavailable is false in
  this state so the degraded-scan substitution does not engage. That is the false
  "agent done" this code's own comment warns about.

The daemon path was already right -- it re-stamps refreshedAt on every positive
recognition -- so the same constant meant two different things in the two files.
Now both mean "time since we last saw the agent", which turns the bound from
"disable the short-circuit after 30s" into "force one revalidating scan every
30s": ~16-31ms per pane per 30s via the native process table.

Test asserts the scan count stops incrementing after the revalidation, and fails
against the stamp-on-change form.

Also correct the shared docstring, which had dropped the invariant the whole
design rests on, and stop calling this a WSL bug: the trigger is a persistent
console-detached job member plus a fallback that reads as a shell. wsl.exe is
not in SHELL_NAMES, so a plain WSL pane does not even reach this code -- WSL is
just where it was measured.

* refactor(windows): shrink the job-membership path

Elegance pass. No behaviour change -- all three mutation checks still bind
(restoring the size>1 veto, stamping only on name change, dropping the root
requirement each turn their tests red).

- windows-pty-job-membership.ts 54 -> 31 lines. A deps object carrying one
  optional function became a defaulted parameter, the accumulate loop became a
  filter, and the docblock lost two thirds of its bulk.

  It also lost a claim that was simply false: it said a widened set "is the
  conservative direction for every caller: it keeps a live agent rather than
  retiring it early". For the retire caller, never retiring IS the failure --
  that is the bug this stack just fixed, still being described as a feature
  three commits later.

- One local `identityOlderThan(ms)` in the tracker replaces two hand-rolled
  `Date.now() - refreshedAt` comparisons, one of which I had added.

- The provider's two parallel maps collapse into one Map<id, {name, at}>.
  Parallel maps meant every delete site had to remember its sibling, in three
  places; the reviewer flagged the leak risk and I fixed it by pairing them,
  which leaves the hazard for the next person. One map removes the class.

Comments trimmed to the load-bearing sentence throughout, per AGENTS.md.

* fix(windows): preserve foreground cache age evidence

* fix(windows): anchor cached agent identity to the pid that proved it

The job short-circuit and retirement veto only knew 'something besides the
shell is alive', so a detached leftover pinned a dead agent's name for the
30s age bound, and 30s of incomplete-but-successful scans could retire a
live one. The scan already knows which row proved the name: carry that pid
through the resolution, and judge the cache against the job with it --
membership of a known pid in a complete, inescapable job list is proof of
life (restamp, never expire), and its absence is proof of exit (retire now,
leftovers notwithstanding). Unanchored identities keep the age-bound
superset behavior.

* fix(windows): anchor the reported process, and let a scan refute a recycled pid

Review findings on the pid anchor:

1. The anchor followed the LEAF that proved a collapsed name: 'omp' reported,
   pi's pid stored. Pi exiting or restarting under a live OMP then read as the
   wrapper's exit -- retiring the identity before a scan that (degraded) may
   miss OMP, a false 'agent done'. resolveOuterWrapperForegroundIdentity now
   carries the pid of the process the name belongs to.

2. A bare numeric pid can be recycled inside the pane's job, making membership
   falsely confirm a dead identity indefinitely. Command lines are immutable,
   so a scan row holding the anchor pid without recognizing as an agent proves
   a different process: the resolution reports it (anchorPidForeign) and both
   consumers retire immediately. A query-denied row (command falls back to the
   image name) stays inconclusive -- never grounds to drop a live agent.

* fix(windows): find a recycled anchor pid in the full table, not the ppid walk

A squatter that inherited the pane job from a leftover whose creator then
exited is orphaned out of the shell-rooted descendant projection, so the
foreign-anchor refutation never saw its row. Pluck the anchor pid's row from
the same whole-table snapshot instead; a job member holding the pid is in the
table even when no ppid chain reaches it.

* fix(windows): survive an agent restart, and refute a squatter by name

Two review findings on the exit verdicts:

1. 'exited' deleted the cache before the scan, so an agent restarting under a
   new pid plus a degraded scan at that instant reported the shell -- a false
   'agent done'. Only the shell standing alone is decisive now; an anchor
   leaving a job that still has members downgrades to unanchored, age-bounded
   evidence and lets the scan decide. The daemon tracker keeps immediate
   retirement: its verdict path only runs after an available scan already
   found no agent.

2. The foreign-anchor refutation treated any recognized row as 'ours'. A pid
   recycled by a DIFFERENT agent now compares against the cached name the
   anchor is supposed to prove.

Neilandinnocarpe 49acb93e2e fix(daemon): let PTY inventory recover from a dead terminal host (#16363)
Worktree removal inventories PTYs through DaemonPtyAdapter.listProcesses. That
called ensureConnected bare, so once the terminal-host pipe was dead the
removal failed with `connect ENOENT \\?\pipe\orca-terminal-host-...` and stayed
broken until the whole app was restarted.

spawn already wrapped its work in withDaemonRetry and recovered from exactly
this. Inventory did not — so the one path that must not get stuck was the only
one that could not heal itself.

Both the connect and the listSessions request go inside the retry: a host that
dies between them throws the same daemon-gone error, so retrying only the
connect would still fail. The reconciliation after the request is deliberately
outside it; retrying that would be wrong.

Reproduced first, with a real daemon killed mid-test: listProcesses threw
DaemonConnectionLostError while a control asserting spawn recovery from the
identical kill passed. Both are now regression tests, so the asymmetry cannot
come back silently.

* revert(daemon): restore merge-base session listing and canceled-spawn behavior

Two behavior changes rode along with the file-splitting refactor:

- listLiveTerminalHostSessions dropped sessions with isTerminating, not just

- spawnAndPublishSession called session.beginTermination() before publishing a
  canceled spawn into the host map.

Both hunks are reverted to the merge base; the refactor is untouched.

Neil e9e238c883 refactor(wsl): delete the environment-policy layer the reviews kept failing on (#16007)
* refactor(wsl): delete the environment-policy layer the reviews kept failing on

A design council (Opus, Grok, GPT-5.6-Sol) reviewed the merged runner after it
took eleven review rounds to land. All three reached the same conclusion: the
invocation half is sound, the environment/probe half is not, and every round had
been debugging the second one.

The finding that settled it, from Opus: `environmentResolved` had **54
references, all in tests and the runner itself. Not one production reader.** The
safety mechanism the strict default existed for was never wired to anything, so
all 19 degrading sites reported absence with full confidence anyway -- #9725
live at every one, under comments claiming it was handled. Two of those comments
say so out loud; I wrote them.

Root cause, in one line: every knob existed only because a failed probe was
fatal. So it no longer is.

- `allowDegradedEnvironment` and `WslGuestEnvironmentUnavailableError` are gone.
  A missing login PATH is a fact in the result, not an exception. That deletes
  23 opt-outs, six catch-and-remap blocks, the transient/rejected cooldown
  split, `probedWithBudget`, and the 1.5x re-probe heuristic -- none of which
  had a reason to exist once the case stopped throwing.
- `lane` + `allowDegradedEnvironment` collapse into `loginPath: 'none' |
  'preferred'`. 19 of 23 sites passed the opt-out, and two said in comments that
  they did not want the login PATH at all: the flag had become the `'none'` the
  union was missing.
- The `interactive` lane is deleted. It had zero production callers and kept ~30
  lines of fence plumbing alive for tests only.

Net -98 production lines; the runner itself sheds 86 for 38.

Also carries three fixes from the W3 orphan-PR sweep I had not done:
- `WSL_UTF8=1` in the runner. My relay migration deleted the only place setting
  it, so wsl.exe's own error text arrived UTF-16LE and read as NUL-riddled.
  A regression I introduced. Credit: #9010 (Chang-Jin-Lee).
- `GITLAB_HOST` is now named in WSLENV, so a ported self-hosted host actually
  crosses into a distro-routed glab (#12557). Credit: #12558 (makoto-developer).
- The WSL skill-setup command pipes into `sh` instead of `eval "$(...)"`, whose
  nested quoting produced `word unexpected (expecting "in")` (#14292). Credit:
  #14785 (innocarpe).

* fix(wsl): restore the login PATH for the Codex availability lookup

loginPath:'none' on a PATH lookup reports an nvm-installed codex as absent,
which is #9725. A miss without a resolved environment is now 'could not
check', not 'not installed'.

Also hardens the guards that should have caught it:
- bashism ratchet is per-call, not per-file, and fails closed on lexer desync
- blankStringContents handles regex literals (an apostrophe in /'/g desynced
  the lexer, so the scan silently found zero calls)
- windowsHide allowlist 85 -> 80, stale once the lexer parsed those files

Credit: Grok (P0), GPT-Sol (ratchet gaps).

* test(wsl): close the two ratchet gaps that let planted spawns pass

- variable-indirected wsl.exe (`const b = 'wsl.exe'; spawnProcess(b)`) is now
  tracked, so the 5 files recorded only in a comment become real allowlist
  entries. Three actually spawn that way; the other two never spawned wsl.exe
  at all, so the prose record was wrong by three in the hiding direction.
- promisify(renamedAlias) is now resolved, so `const run = promisify(execFile)`
  behind an `execFile as x` import can no longer skip windowsHide.

Each verified by planting the violation, watching it fail, restoring, watching
it pass. Credit: GPT-Sol.

* fix(source-scan): stop the regex-literal reader from eating block comments

At index 0 there is no preceding token, so a file opening with a banner
comment had its `/*` read as a pattern and swallowed to the next slash --
110k characters of preload/index.ts, in the direction that hides offenders.

Measured across the tree, old lexer vs new: worst-case over-blanking drops
from -110564 to -1116 characters, and files that desync drop from 51 to 22.
The remaining extra blanking is regex interiors, which is the intent.

Regression tests for both lexer bugs, each verified to fail with its fix
reverted. The first draft of the comment test did not bind -- it asserted on
text after the swallowed span.

* fix(wsl): restore the unverifiable signal on the two remaining probe sites

Round 2. Three call sites used to throw when the login-PATH probe failed;
the redesign rewired one (Codex) and left two reporting confident absence.

- skill-wsl-provider-detection: the script ends in `|| true`, so a lookup
  without the login PATH exits 0 with empty stdout -- identical to 'nothing
  installed'. Callers skip the ~/.codex and ~/.claude skill roots on an empty
  list, losing an nvm-installed provider's skills.
- wsl-cli-installer: the dead catch is replaced by an explicit check. Its
  `case ":$PATH:"` probe otherwise answers from the distro default PATH and
  Settings states as fact that the CLI is not on PATH. Timeout is checked
  first, since a timed-out run also leaves the environment unresolved.

Also narrows the regex-literal prev-token set. '!', '+', '-', '>' and '}' are
value terminators as often as operators, so postfix `n-- / 2` and JSX
`<A size={14} /> : <B` were read as patterns and their spans blanked -- 13
live JSX spans, and one swallowed execFile call that left no desync behind.
False negatives only risk a desync, and desync fails closed.

Plus: WSL_UTF8 on the probe spawn (#9010 reached the runner, not the probe),
and the allowlist header I shuffled by sorting comments along with entries.

Credit: Grok (both P1s), Opus (lexer false positives).

* docs(wsl): drop the lane comments the redesign made false

The interactive lane is gone, so 'both lanes' and the fenced-stdout note
described code that no longer exists. Also states plainly that
environmentResolved is always true under loginPath:'none' -- the field cannot
rescue a PATH lookup that was mislabelled, which is how #9725 came back.

Credit: Grok.

* fix(wsl): stop piping user scripts into the shell's stdin

The W3 migration moved hooks from `wsl.exe --exec bash -c <script>` to a
script piped into `bash -s`. Anything the script runs that reads stdin then
drains the rest of the script, bash hits EOF and exits 0, and the caller logs
success -- an orca.yaml hook of `ssh -T git@github.com || true` followed by
`pnpm install` silently never installs.

Scripts now travel in argv by default, which is what the pre-migration code
did and what --exec makes safe. `scriptDelivery: 'stdin'` stays for the one
caller that needs it: the hook-relay installer embeds a base64 JS bundle far
past any command-line limit, and reads no stdin.

A runner test already described this exact EOF hazard -- for the login shell,
not for the guest command it was itself creating.

* fix(skills): make the unverifiable check unconditional, and stop double-probing

Round 3.

- provider detection threw only on an EMPTY result, so a degraded partial hit
  slipped through: `claude` visible on the default PATH via Windows interop
  plus an nvm-only `codex` returns a plausible ['claude'], and the caller then
  skips the ~/.codex skill roots for a provider that is installed. The
  installer already got this right with an unconditional throw.
- three sites asked for 'preferred' without needing it. The GROK_HOME probe
  runs its own `"$login_shell" -lc`, so the runner's probe was a second login
  shell eating up to half an 8s budget; the two skill scans are
  find/base64/head/printf/stat over $HOME.
- the indirection binder missed `private readonly x = 'wsl.exe'` (the
  modifier was captured as the name), backtick literals, and
  `spawnProcess(this.x)`. Commit 2bbbd99 claimed that gap closed; it now is,
  verified against all three shapes.

* fix(child-process): keep the tail of output whose failure lands last

Two console-flash bugs the ratchet was carrying on its allowlist rather than
catching: daemon-process-inspection execs powershell.exe and the gemini
extractor execs `where gemini`, both console-subsystem, both without
windowsHide (#10488). Allowlist 80 -> 78.

And a migration regression: the hook-relay install used to keep a rolling
tail of stderr (`slice(-MAX)`), while runProcess's maxOutputBytes keeps the
head. A guest install that fails after pages of apt warnings therefore
reported the warnings instead of `mv: Read-only file system`. runProcess
takes retainOutput: 'tail' for output whose meaning is at the end.

Credit: code review.

* test(wsl): close the last two indirection shapes in the binder

`this.binary = 'wsl.exe'` has no declarator keyword, and a helper that just
returns the literal is a spawn one hop away that no regex can follow. The
return case fails closed only when the file also spawns something --
local-windows-terminal-runtime.ts returns the name as terminal metadata and
never spawns, so a blanket rule flagged it wrongly.

Verified against both shapes: planted, failed, restored, passed.

Credit: Opus.

* fix(preflight): stop reporting installed WSL CLIs as absent (#9725)

The last two probe sites that turned an unresolvable login PATH into a
confident negative. The native branch of detectInstalledAgents already
consults install dirs for exactly this reason ('PATH may still be unhydrated
on a cold GUI launch'); the WSL branch had no equivalent, so a cold distro
made an nvm-installed claude/codex read as not installed and told the user to
install a CLI their own terminal runs.

Ports that fallback to the guest: agent detection checks the version-manager
bin dirs for commands the PATH lookup missed, and the preflight command runner
APPENDS them to PATH -- append, never prepend, so a resolved login PATH stays
authoritative and a stale nvm version cannot shadow the real binary.

Tested by executing the generated scripts through /bin/sh against planted
binaries, since the behaviour is shell globbing and [ -x ]. Both the
nvm-discovery and the no-shadowing tests were verified to fail when reverted.

* fix(codex-accounts): hide the console on the legacy active-home migration

execFileSync('wsl.exe') with no windowsHide flashes a conhost and steals
foreground on a GUI-launched Orca (#10488). Sibling WSL spawns got this in
earlier commits; this one only had its quoting rewritten. Allowlist 75 -> 74.

Credit: code review.

* fix(windows): close the shell:true hole that made windowsHide a no-op

I un-allowlisted the gemini extractor after adding `windowsHide: true` to an
`exec()` call. `exec` implies `shell: true`, which this repo's own chokepoint
documents as silently making windowsHide a no-op (#14543) -- so the site still
flashed a conhost while reading as guarded. Now execFile('where.exe', …),
matching the relay sibling that already did it right.

The ratchet could not see that, which is why it passed. It now treats a call
that resolves to exec/execSync, or any `shell: true`, as unguarded regardless
of windowsHide -- including through renamed imports and a renamed promisify.

Also: a script over 8000 chars now falls back to stdin. Windows caps a command
line at 32767 and a user's orca.yaml hook is the one unbounded script Orca
runs (`run-both` concatenates two; a vendored installer is ~15KB), so argv
would fail to spawn outright. Degrading beats failing.

And the binder now sees `let p: string` ... `p = 'wsl.exe'`.

Each verified by planting. Credit: Grok.

* test(wsl): an opaque payload must declare its interpreter

My per-call bashism guard REPLACED the file-wide one, and that was a strict
regression: the real payloads are built in a separate function and passed as a
bare `script,`, so the bashism is never inside the call literal and the
per-call arm cannot fire. Deleting `shell: 'bash'` from skill-discovery-wsl
-- `done < <(find ...)` and `read -r -d ''`, the #14292 signature -- passed on
this branch and failed on main.

Reading through the identifier is guesswork. Requiring the call to name its
shell when the payload is not a literal is not, so seven POSIX call sites now
say `shell: 'sh'` -- no behaviour change, sh was already the default.

Two earlier attempts at this were wrong and are worth recording: a whole-file
BASHISM test blamed codex-accounts/service.ts, which correctly pins bash on its
four inline payloads and correctly leaves printf/mkdir unpinned; and excluding
call text still caught a bash payload belonging to a non-runner execFileSync.

Also: runProcessSync now refuses retainOutput:'tail' instead of silently
keeping the head, and the union docblock no longer describes stdin delivery.

Verified against both of the plants that exposed this. Credit: Opus.

* test(wsl): judge an opaque payload by the file, not by whether shell is set

Round 5. My previous rule -- opaque payload must have `shell:` -- was the
third guard fix in a row that came out weaker than what it replaced:
`shell: 'sh'` on a bash payload satisfied it, which is #14292 with extra
steps. Flipping skill-discovery-wsl's pin from bash to sh shipped green.

Now: strip the text of every call that already names bash, and if a bashism
survives anywhere in the file while a script-carrying call is not bash-pinned,
flag it. Stripping the bash-pinned calls is what keeps codex-accounts clean.

Also closes four ways to hide a call from the collector, each verified by
planting:
- `script: \`${bashism}\`` -- a template literal read as a visible literal
- `runWslProcess({ ...spec })` -- a spread hides script AND shell
- `Object.assign({ a }, { script })` -- the collector took the first `{`, so it
  now takes the whole argument list
- `import { runWslProcess as runWsl }` -- a renamed callee collected nothing,
  and zero calls read as zero violations

Not fixed, recorded instead: a computed `shell:` in the console guard. Matching
any non-false value also flags `shell: spawnConfig.shell`, a pass-through that
is false in every branch, and a false positive there costs an allowlist entry
that disables the guard for a whole correct file.

Credit: Grok.

* fix(preflight): make the guest fallback match the native one it claims to mirror

Three defects in the #9725 fix from earlier today, all found by executing the
generated scripts under real dash rather than reading them.

- $HOME containing a space word-split the unquoted dir list into a relative
  path, so every CLI read as absent -- the exact symptom the fix exists to
  remove. Each entry is quoted now; the nvm entry quotes only its prefix so the
  glob still expands.
- A directory passes `[ -x ]`, so ~/.local/bin/gemini/ was reported as an
  installed CLI that then fails to launch with EISDIR. The PATH half of the
  same script already guarded this, and so does the native twin.
- The header called this the "guest-side twin" of the native fallback while
  omitting four of its directories: volta, asdf, fnm and mise. A WSL user on
  any of those still had #9725 while the same user on native did not -- and
  asdf and mise are named in the motivating comment. The claim is now true.

Credit: Opus.

* test(wsl): mask bash-pinned calls by position, not by String.replace

`rest.replace(text, '')` with a string pattern removes only the FIRST match,
so two identically-written pinned calls left one behind and its bashism then
counted against an unrelated unpinned call in the same file. A body that also
occurred earlier as a substring would blank the wrong region entirely.

The collector now returns ranges and the mask is applied by index. Verified
both directions: two identical pinned bodies plus one unpinned call flags, and
the same file with all three pinned stays clean.

* test(wsl): fail closed on call shapes a regex cannot attribute

Round 6. Rather than widen the pattern again, treat the shapes it cannot
reason about as unreadable.

A regex cannot tell which object a key belongs to, so every round produced
another way to put the pin in one place and the payload in another:
`cond ? {pinned} : {unpinned}`, `{...} as WslSpec`, `Object.assign({a},{b})`.
A call whose SPEC is chosen by a ternary or spread -- one appearing before the
first `{` -- or which carries an `as` assertion is now flagged whenever the
file has a bashism, with no `shell: 'bash'` escape, because the substring test
that would grant the escape is exactly what cannot be trusted on these shapes.

A ternary INSIDE the object is not exotic: claude-accounts/service.ts:977 uses
one to choose a script line in a call that is already pinned, and treating that
as opaque would demand a second pin it already has. Nor is a nested call --
`script: `x ${shellQuote(p)}`` is how every payload here is built, and flagging
it would demand bash on POSIX payloads that must not have it.

Also follows `const run = runWslProcess`, generics and optional chaining, and
counts collected calls against mentions so a shape that slips the pattern reads
as unreadable rather than clean.

I tried the TypeScript parser first, which would remove the class outright.
TypeScript 7 is the native port and exposes no JS compiler API; oxc-parser
works but is transitive, and declaring it surfaced an unmet peer warning.
Recorded here so the next person does not repeat the detour.

Credit: Grok.

* fix(wsl): fish is a PATH lookup, and my lint check could not fail

Two things Opus caught that I had verified wrongly.

`wsl-fish-history-cleanup` passes `program: 'fish'` -- a bare name, so a PATH
lookup by definition, the exact class the earlier rounds hunted. I mapped it to
'none' and then defended that in an audit, because I read
`allowDegradedEnvironment: true` as "does not need the login PATH". It does not
mean that: it means "do not fail when the probe fails". The old call still USED
the login PATH whenever it got one, which is 'preferred'. Under 'none' a fish
from linuxbrew or nix is invisible and the cleanup throws. The truncated
comment left behind when the flag was deleted is finished too.

And `pnpm lint` has been failing on this branch while I reported it clean: I
grepped for `error eslint|error oxlint`, but oxlint prints the rule category
(`error typescript(array-type)`, `error unicorn(prefer-ternary)`). The grep
could not match, so it never failed. Checking the exit code instead surfaced a
third violation hidden behind the first two.

Credit: Opus.

* chore(wsl): clear the round-7 P2s

- Formatting: the branch owned 22 of the tree's 26 oxfmt failures because I
  never ran the formatter. Branch files now own none.
- resolveScriptDelivery was computed twice, in two places that must agree
  about argv shape and stdin payload. Resolved once and threaded through.
- The allowlist header said the list only shrinks while the branch added three
  entries. It grew because the scanner learned to follow a variable-bound
  'wsl.exe'; those three were previously recorded in prose, so the count was
  wrong by three in the direction that hides offenders. The header now says so.
- Two test comments still explained behaviour via the deleted
  allowDegradedEnvironment flag; a stray triple blank line; two adjacent JSDoc
  blocks where only the second attached.

Not taken: platform-guarding addWslEnvKeys. WSLENV is inert off Windows, and
the guard broke a test that asserts the key directly -- more surface than the
tidy is worth, so the reason is recorded at the call site instead.

Credit: Opus.

* test(preflight): plant a fabricated CLI name, not a real one

CI caught what my local run could not: the runner has a real /usr/bin/gh, so
`command -v gh` resolved to it and the planted nvm stub was never reached. The
fallback APPENDS, so that is the code behaving correctly -- the test was
asserting a property of my machine.

Both real-shell suites now plant `orca-fake-cli`, which exists nowhere.
Re-verified the same way as before: with the PATH fallback disabled the test
fails, with it restored it passes.

I declared this branch merge-ready without looking at CI. Local green is not
the gate.

* refactor(wsl): delete two knobs and a duplicated fallback

Elegance pass. The branch had grown from a deletion into a net addition, and
most of the growth was optional axes with one caller each.

- `retainOutput` is gone. One production caller wanted the tail of a 64KiB
  buffer; head-truncation only hurt because of that cap. The caller drops the
  cap, keeps the default, and slices the tail itself -- which is what the live
  relay next door already does. Two mechanisms for one job became one.
- `scriptDelivery` is gone. The size rule was already the whole design:
  argv unless the script is too long for a Windows command line. The option
  existed so a small Orca script could opt into stdin, and no such caller ever
  appeared. Both behaviours stay pinned: a huge script still goes to stdin, an
  ordinary one still leaves the hook's stdin free.
- Agent detection no longer walks the fallback dirs itself. It prepends the
  same PATH prelude the preflight command runner uses and lets the ordinary
  lookup do the work. Its bespoke walk had duplicated the lookup script's
  `! -d` guard -- and had missed it once, which is how a directory read as an
  installed CLI.

All 17 detection tests still pass unchanged, including the $HOME-with-a-space,
directory-is-not-a-CLI, and volta/asdf/fnm/mise cases, so the collapse is
behaviour-preserving rather than assumed to be.

Credit: Grok.

* fix(wsl): never name a path-shaped variable in WSLENV

`buildHostEnv` forwarded every caller-supplied key into WSLENV. wsl.exe
translates path-shaped variables between Windows and Linux form, so a caller
passing PATH would have replaced the guest's own PATH with a translated
Windows one -- silently, and fatally for every lookup after it.

No caller passes PATH today. The point of a chokepoint is that it does not
depend on that staying true.

ecfc547ece fix(windows): reach the pty job on the teardown path that actually runs (#15886)
W2 gave every ConPTY pane a job object and wired `terminateOwnedTree` into
`local-pty-provider.ts`. Measured in #11047: worktree delete does not execute
there. It runs in the terminal daemon, so on the path that matters the sweep
still fell back to a parent-pid walk -- which a detached, reparented grandchild
is not in. That process is the one that holds the worktree cwd open, so the
delete this was meant to fix could still fail.

Expose the job on `SubprocessHandle` and use it at the three daemon call sites
(`terminal-session-teardown.ts` x2, `session-termination-controller.ts`).

Also: on Windows `forceKill()` returned early after any `kill()`, to avoid
double-closing the ConPTY handle node-pty owns. Correct, but it left force-kill
a permanent no-op -- and a wedged ConPTY never fires `onExit`, so such a session
had no escalation at all (#9854). Terminating the job is that escalation, and it
does not touch node-pty's handle.

A tree-walking guard now fails if any production `killWithDescendantSweep` call
omits `terminateOwnedTree`, since the option is optional by design and its
absence is invisible in review -- exactly how this gap survived W2.

Neil 2b1254d681 fix(windows): own PTY process trees with job objects (#15755)
* fix(windows): own PTY process trees with job objects

Teardown used to answer 'is this tree mine, and how do I kill it?' by
scraping the process table, walking parent pids back to Orca, and running
taskkill /T /F only if the walk said yes. Every step is a guess, and the
code said so itself: windows-pty-root-identity.ts:35 already named the
fix -- 'an inherited handle / Job Object'.

The guesses fail in the ways users report. A pid walk cannot survive pid
reuse, so teardown refused whenever it could not prove ownership, and a
refused kill is an orphaned agent tree holding the worktree directory
open (#9045, #10475, #10087). A descendant that reparented is invisible
to the walk. The scrape itself could be blocked by policy, which read as
'no evidence'.

node-pty now creates a job object per ConPTY and assigns the shell under
CREATE_SUSPENDED, before it can spawn anything -- assigning afterwards
leaves a window in which a fast child escapes. Termination is one
TerminateJobObject; liveness is QueryInformationJobObject.

Verified on Windows 11 against a shell whose grandchild was spawned
detached: job membership came back [shell, grandchild] and one call
killed both. Neither a parent-pid walk nor GetConsoleProcessList sees
that grandchild -- it leaves the console and reparents, which is exactly
the claude.exe/node.exe/cmd.exe orphan in #9045.

KILL_ON_JOB_CLOSE means a daemon that dies without unwinding no longer
strands shells (#9195, #10415). The job is the daemon's, not the app's,
so an app-main crash still leaves sessions alive -- the guarantee
win-crash-survival-e2e asserts.

Both entry points report unavailable rather than a false success when a
pty has no job: an outer job without BREAKAWAY_OK can refuse the
assignment, and a pty from an older build has none. Reading 'we could
not tell' as 'already dead' is the original bug, so the old probe stays
as the fallback.

* test(windows): pin job ownership against a real detached grandchild

The unit tests pin the contract; this pins what the contract is for. A
grandchild spawned detached leaves the pane's console and reparents, so
GetConsoleProcessList and a parent-pid walk both miss it -- that is the
process that outlived its pane and held the worktree directory open.

Includes a guard that this build actually has job support, so a node-pty
rebuilt from unpatched sources fails loudly instead of letting every
assertion pass vacuously.

* fix(windows): correct the job liveness contract to what Windows actually does

I claimed an emptied tree would report [] and that this was the evidence
a stale registry entry lacks (#15549). Running it on Windows 11 showed
otherwise: node-pty drops its handle record and closes the job when the
shell exits, so a dead tree reports null.

Null therefore means unverifiable in the sense of
docs/reference/ssh-execution-boundary.md -- no job support, not a ConPTY,
or no longer tracked -- and is never evidence that processes died. A
caller reading it as proof of death would have been right by accident
after a normal exit and wrong on a host that refused the assignment.

What the API does add is descendant liveness for a tree that is still
tracked, including children that detached from the console.

* fix(windows): stop a clean shell exit from reaping backgrounded processes

Measured on Windows 11: with JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE on the
per-PTY job, releasing the handle when the shell exits also killed
whatever the user had backgrounded. Typing 'exit' in a pane reaped a
detached server that survived before this patch.

That is a behaviour change nobody asked for. The approved change was
that killing the terminal daemon reaps its shells -- not that a clean
exit reaps your background job. The job's purpose is to make an EXPLICIT
teardown exact, which TerminateJobObject still does.

Reaping a dead daemon's shells now needs the daemon-level job the design
called for: the daemon assigns itself, children inherit membership, and
its closure on daemon death reaps them without touching clean-exit
semantics. Not in this PR; noted in the reference doc.

* test(windows): pin that a clean exit leaves backgrounded work alone

The counterpart to the tree-kill test. Without it, re-adding
JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE would look like a tightening rather
than the regression it is.

* fix(windows): stop a winpty pty id from matching a ConPTY job

winpty.cc and conpty.cc each mint their 'pty' id from an independent
counter, and windowsPtyAgent stores both in the same _pty field. So a
winpty-backed terminal's id can collide with a live ConPTY baton -- and
closing that pane would have terminated an unrelated pane's entire
process tree.

Both job entry points now take the shell pid and the native side refuses
unless GetProcessId(hShell) matches, which makes the id unforgeable.

Two more from the same read-through:
- ResumeThread's failure was ignored. A shell left suspended is a pane
  that never prints and never exits, which is far harder to diagnose
  than a failed spawn; it now cleans up and throws.
- handle->hJob was assigned before LoadConptyDll, which can throw. A
  baton carrying a job but never reaching SetupExitCallback has nothing
  left to close it, so the assignment moved down beside hShell.

* docs(windows): record the unsynchronised node-pty baton table

Pre-existing upstream -- the exit thread erases while the main thread
reads -- but terminatePtyJob adds an instance of it, so it belongs in
writing rather than in someone's head.

* fix(windows): close four gaps found in review

BREAKAWAY. The per-PTY job set no limits, so a child asking for
CREATE_BREAKAWAY_FROM_JOB was refused with ERROR_ACCESS_DENIED.
Installers, msiexec and some updater and service-control paths spawn
that way deliberately -- they worked before this patch and would have
failed only inside an Orca terminal, which is the worst shape a bug
report can take. JOB_OBJECT_LIMIT_BREAKAWAY_OK restores it; a child
still has to ask, so ordinary descendants stay owned.

EMPTY IS NOT UNAVAILABLE. The native reader returns an empty list --
not an error -- when CreateToolhelp32Snapshot fails, which is what an
EDR hook or a restricted token produces. Callers read that as 'nothing
is running' and teardown concludes a live PTY root is already gone. The
snapshot must contain the querying process; nothing else is
unfalsifiable, and one predicate catches empty, truncated and
permission-filtered tables alike.

NO DEADLINE. Replacing execFile dropped its 3s timeout. The vendored
reader latches a module-global while a request is in flight and clears
it only after draining its callbacks, with no try/catch -- so one wedge
leaves every later call queued behind a promise that never settles, and
the process table is dead for the life of the app. The bound is back.

GUESSED IMAGE PATH. executablePath was derived from the first
space-delimited token, which reads 'C:\Program' out of an unquoted
'C:\Program Files\nodejs\node.exe ...'. Wrong evidence is worse than
none, and the only consumer already had the full path in , so
the field is gone rather than repaired.

Also: remove_pty_baton no longer sits inside assert(), which NDEBUG
would compile away along with the call, and the job accessors hold a
lock across lookup and use -- handle values are recycled, so an
unguarded read could pass the shell-pid check against an unrelated
process and terminate the wrong job.

* fix(windows): apply the job lock once per accessor

The patch script matched a string its own replacement still contained, so
PtyTerminateJob got two lock_guards named guard and PtyListJobProcessIds
got none. MSVC caught it: error C2374 redefinition.

* test(windows): pin that a child can still break away from the job

Verified on Windows 11: 'start /b' writes its marker and no access-denied
appears. Without JOB_OBJECT_LIMIT_BREAKAWAY_OK this fails, and it fails
only inside an Orca terminal -- so the failure would look like Orca
corrupting unrelated software rather than like a job-object change.

* fix(windows): stop the ownership guard from reading a closing handle

The guard called GetProcessId(hShell) to prove identity, but the exit
watcher closes hShell on another thread -- so the guard could read a
closed handle, and under strict handle checks that is fatal rather than
merely wrong. Worse, it widened the gap between validating hJob and
using it from two instructions to a kernel round-trip, and handle values
recycle: the likeliest occupant of a freshly recycled value in this
process is another pane's job.

The pid never needed a handle. It is captured at spawn and compared as a
DWORD, so the guard touches no handle at all, and hShell is now closed
inside the same lock as hJob.

Also from review:
- reject CR/LF in a cmd argument. cmd ends the command at a raw line
  break whatever the quote state, so there is no escape for it; encoding
  one anyway truncates the argument and can leave the remainder to run
  as a command. Agent prompts are this encoder's motivating input.
- ask the process table only for the fields a caller needs. Memory and
  CommandLine each cost an OpenProcess per process, inline, for every
  process on the box -- and the 1024 bound is patched out. Ancestry
  reads now skip both.
- corpus gains the degenerate quote-only and two-quote arguments.
- PtyListJobProcessIds' docblock still taught the empty-list contract
  that was corrected on the TS side, and now records that the ConPTY
  console host is never a job member.
- drop a write to NumberOfAssignedProcesses, which is output-only.
- pty_baton::hShell is initialised; ownsShell was only safe because &&
  short-circuited ahead of it.

The backgrounded-child test is rescoped: 'start /b' uses
CREATE_NEW_CONSOLE, not CREATE_BREAKAWAY_FROM_JOB, so it proves job
membership does not block backgrounding -- not that BREAKAWAY_OK works.
That flag rests on the Win32 contract, and I have said so rather than
letting the test imply coverage it does not have.

* fix(windows): bound retries after the process table wedges

The 3s deadline stops a caller hanging, but the timed-out call leaves its
callback in the vendored module's queue -- and that queue drains only
when the latched request completes, which in this wedge never happens.
Retrying at the caller's poll rate would add a closure per tick forever.
A 30s cooldown bounds it to one probe, and a late callback clears the
cooldown because it proves the reader recovered.

Also pins the deadlock invariant in the patch: the exit thread's lock
must close before tsfn.BlockingCall, because that waits on the JS thread
and the JS thread can be waiting on the same mutex inside
PtyTerminateJob. Correct today by scoping; a comment so a later refactor
does not widen it.

* revert(windows): drop the field-selection API, which cannot pay off

I added it for a real perf finding -- Memory and CommandLine each cost an
OpenProcess per process -- and then never wired a caller, so the claim
that ancestry reads skip them was wrong.

Wiring it would have been worse than leaving it dead. The only ancestry
consumer is the teardown identity probe, which needs a snapshot that
started AFTER it asked, for pid-recycle detection. Bypassing the shared
reader to get narrow fields would let that request join a scan already in
flight -- trading a correctness guarantee for milliseconds.

Field selection only pays off if callers can ask for less, and they
cannot: one shared snapshot serves every caller so a 32-wide teardown
collapses into a single scan, which means it has to carry every field.
The reasoning now lives next to the flags instead of in a dead export.

* fix(process): three P1s from review — a crash vector and two wedge bugs

STDIN EPIPE COULD TAKE DOWN THE MAIN PROCESS. A child that exits without
reading makes the queued write fail with EPIPE, and an unhandled error on
a stream is an uncaught exception. The child's own error listener does
not cover its stdin stream, so runProcess({ input }) against a
short-lived child was a crash, not a failed call.

THE COOLDOWN LEAKED A BATCH PER CYCLE INSTEAD OF BOUNDING IT. At expiry
every concurrent caller passed the check before any of them re-armed it,
so each enqueued a callback into the still-latched native queue and each
cycle leaked another batch. The cooldown is now re-armed BEFORE probing,
so exactly one caller gets through.

A SYNCHRONOUS THROW LEFT ITS DEADLINE RUNNING. The timer was declared
inside the try, so catch could not clear it; it fired later and wedged a
reader that had already recovered. Hoisted and cleared, and wedge state
now carries a generation so a request that lost its deadline cannot
mutate it on behalf of the one that replaced it.

Found by review once the prompts were short enough for the reviewer to
finish -- the previous two rounds died on prompt length.

* fix(process): stop a stream error from crashing the main process

Same class as the stdin EPIPE finding, two instances further on: stdout
and stderr had data listeners and no error listeners, and an unhandled
error on a stream is an uncaught exception.

Scoped to runProcess, which owns the child outright. spawnProcess hands
the streams to its caller, and a blanket handler there defeats callers
that track and remove their own listeners -- the SSH ProxyCommand
transport does exactly that, and its cleanup test caught the attempt.
Documented on spawnProcess so the boundary is explicit rather than
inferred.

* fix(windows): validate the ConPTY DLL before creating the process

LoadConptyDll throws when conpty.dll is missing -- a real state, and one
this branch hit during development. It ran after CreateProcessW and
ResumeThread but before the baton and the exit watcher were installed,
so a throw leaked the job, process and thread handles and left an
untracked shell tree running. Once per attempt, so a broken install
accumulates orphan shells on every retry.

Resolving the DLL first costs nothing and leaves exactly two throws
after creation: the CreateProcessW failure, where nothing exists yet,
and the resume failure, which already cleans up after itself.

This also closes the same leak for hProcess and hThread, which predates
the job work.

* feat(windows): add the daemon-level job the design called for

The plan specified two nested jobs and I built one. That gap is why
dropping KILL_ON_JOB_CLOSE from the per-PTY job cost the approved
guarantee that a dead daemon reaps its shells -- I had one job trying to
answer two questions, and the two answers conflict.

They are separate jobs. The per-PTY job answers 'kill exactly this
pane's tree, now', and cannot be kill-on-close because its handle is
released when the shell exits, which would reap whatever the user
backgrounded. The daemon assigns itself to a second job that IS
kill-on-close; its handle is released only when the daemon dies.
Children inherit membership, so every pty is covered and the per-PTY
jobs nest inside it.

Daemon, never app: an app-main crash must still leave sessions alive,
which win-crash-survival-e2e asserts. Both jobs carry BREAKAWAY_OK, or a
child asking to break away is refused at whichever level lacks it.

Restores #9195 and #10415, which I withdrew from this PR earlier.

* docs(windows): record what the host job does not cover

An app-hosted PTY gets a per-PTY job but no crash reaping, because the
alternative is a kill-on-close job on the app -- which is precisely what
the crash-survival guarantee forbids.

* ci(windows): run the win32 suites in the PR windows job

Both were skip-on-non-win32 and had only ever run on one machine I drive
by hand -- which went unreachable at exactly the moment I needed to
verify the percent-escaping fix. Verification that depends on one box is
not verification.

The job already builds node-pty from patched source and already runs a
useConptyDll test, so the ConPTY runtime files are in place by this
step. This also makes the encoder a gate: the corpus is the only thing
standing between an agent prompt and a mangled argv, and it now runs
against real cmd.exe on every PR.

* fix(deps): refresh the lockfile for the current patch hashes

pnpm records a hash per patched dependency, and I regenerated both
patches repeatedly across the review rounds without refreshing the
lockfile. Every local run used --frozen-lockfile's looser sibling, so
nothing caught it until CI did:

  ERR_PNPM_LOCKFILE_CONFIG_MISMATCH  Cannot proceed with the frozen
  installation. The current "patchedDependencies" configuration doesn't
  match the value found in the lockfile

Verified with pnpm install --frozen-lockfile locally this time.

* ci(windows): build node-pty from source before the win32 suites

CI proved the encoder fix on real cmd.exe -- 26/26 -- and in the same run
proved the job suite had been testing an unpatched binary. node-pty
prefers its upstream prebuild, which does not contain this patch, so
every job-object export was absent and isPtyJobOwnershipAvailable() was
false.

That guard is why the failure was loud rather than a vacuous pass, and
it is the reason the assertion exists.

Packaging was never affected: rebuild-native-deps.mjs already builds
node-pty from source for Electron and restores the ConPTY runtime files.
The gap was the node-runtime test environment only.

Not changing requiresPatchedNodePtySourceBuild's win32 exemption here.
Its premise -- that the patch is Unix-only -- is now false, but lifting
it also needs pnpm rebuild to force a source build, and I cannot
validate that on macOS and Linux from here. Recorded as a follow-up
instead of changed blind.

* test(windows): gate the host-job guarantee in CI

The daemon-level job had one hand-run proof and no automated coverage --
the same shape of gap that let an unpatched node-pty go unnoticed until
CI caught it.

It needs a real second process, because the assertion is about what
happens when that process is force-killed: a host in a kill-on-close job
must strand neither its pty nor a grandchild spawned detached, which is
the process a parent-pid walk cannot see.

Runs in the Windows PR job alongside the per-pty and encoder suites, so
both halves of the two-job design are now gated rather than asserted.

* fix(windows): serialise host-job creation

Two callers racing PtyAssignCurrentProcessToJob would each create a job,
put the process in both, and leak the first handle -- and the handle is
what keeps a kill-on-close job alive, so a leaked one is never released.
'Only JS calls it' is not a guarantee: a worker thread with its own
N-API env shares these statics.

Also records the ordering requirement it depends on.
AssignProcessToJobObject adds only the named process; children inherit
membership, but a pty that already exists does not join retroactively
and would not be reaped. The daemon assigns at startup, before the
ConPTY warmup and before any session, which is correct today and now
stated rather than implied.

* fix(daemon): keep the host job off the startup path

Assigning the host job at daemon startup resolves the node-pty native
module, which loads the ConPTY addon -- and paying that before the
endpoint is published delayed readiness enough that daemon-boot-smoke
failed on windows-latest, deterministically.

windows-conpty-warmup already carries the comment for this exact
hazard ('setImmediate keeps the ready/handshake path ahead of the
warm-up') and I put an eager load in front of it anyway.

Moved to the pty spawn path, which already pays ConPTY cost, and
memoised. Children inherit job membership, so assigning immediately
before the first spawn still covers every pty -- and nothing can spawn
one before the endpoint exists.

JinjingandJinwoo-H 6e25a90085 fix(terminal): keep a quick command queued until its own spawn takes it (#15630)
* Increase shell readiness timeout to match daemon barrier

Slow interactive rc files can take longer than 1.5s to initialize. Raise
the startup command readiness timeout from 1.5s to 15s to match the daemon
barrier and prevent queued commands from executing mid-startup.

* fix(terminal): keep a quick command queued until its own spawn takes it (STA-4876)

Triggering a quick command opened a terminal tab titled with the command's
label, the shell started and drew its prompt, and the command never ran.

TerminalPane snapshots `pendingStartupByTabId[tabId]` in a useState lazy
initializer, and a mount effect deleted the entry immediately. The pane's key
is `${tab.id}-${tab.generation ?? 0}`, so anything that bumps generation before
the command reaches a shell — the stall-recovery remount fired from
`requestTerminalPaneRecovery`, or the allDead activation regeneration — mounted
a second pane that re-read an emptied slot and spawned with no command at all.
The loss was permanent, which is why every scope failed alike: repo, global and
agent-prompt all funnel through the same queue-then-snapshot sequence.

Spend the entry at `onPtySpawn` instead, which is the one point that proves this
pane's own fresh spawn exists. A pane retired mid-connect never reaches it, so
the command stays queued for the next mount; reattach skips `onPtySpawn`, so it
cannot spend a command it never delivers.

Three details are load-bearing:

- Ownership is reference identity (`paneOwnsQueuedStartup`). Setup and issue
  splits borrow the same `deps.startup` field for their own one-shot payload, and
  that payload can be structurally identical to the queued command, so a
  truthiness test would let a split pane spend a command it never runs.
- The consume runs after `bindActivePanePty`. While the tab still has no ptyId,
  the queued entry is the only thing holding its worktree out of the
  retention-budget force-park, so dropping it first unmounts the pane mid-spawn.
- The callback is one-shot. `onPtySpawn` fires on every fresh spawn a pane makes,
  including hibernation wake and the respawn ladder, and a command queued after
  the first launch belongs to that later launch.

Known residual, documented at the call site: the consume tracks "a pty exists",
not "the command ran". Windows embeds short commands in the shell argv, so they
execute before the spawn resolves and a pane retired in that window re-delivers
on remount; on POSIX the write waits for shell-ready, so a pty that dies in that
window loses a command already spent. Closing either needs a delivery signal
from main rather than this callback. Both windows are narrow, and both are
strictly better than losing the command unconditionally.

* fix(terminal): guard the queued-startup wiring the review found untested

Follow-ups from the final review pass on this branch.

- Collapse the ownership + one-shot decision into `createQueuedStartupConsumer`
  so the call site is a single call rather than inline logic no test could
  reach. Two mutants survived the whole suite before this: relaxing ownership to
  a truthiness check, and dropping the one-shot guard. Both now fail.
- Rewrite the throwing-consume test. It asserted `updateTabPtyId` had been
  called, which runs *before* the callback, so it passed with the try/catch
  deleted. It now asserts the throw does not escape into the connect promise,
  which is the invariant the try/catch actually provides.
- Correct the `onQueuedStartupSpawned` docblock. It claimed the callback is "the
  first moment the command is guaranteed to reach a shell"; the diff's own caveat
  says otherwise, since Windows runs an argv-embedded command before this fires
  and a POSIX shell can die before the shell-ready write. It marks a live shell,
  not delivery.

No behavior change: the consumer is the same predicate and the same one-shot,
moved behind one exported seam.

* fix(terminal): roll shell wrapper isolation into a fresh daemon

* Revert "Increase shell readiness timeout to match daemon barrier"

This reverts commit 6ab273ef36.

* Condense queued startup spawn comment

Simplify the multi-paragraph explanation into a concise summary that captures the key points: spawn must wait until after the pane is bound to preserve the worktree from force-parking, and the behavior differs between POSIX and Windows for delivery timing.

* fix(terminal): prevent consuming replaced queued startup commands

When a queued startup is replaced before the pane's first spawn,
the one-shot guard alone still allows consuming the replacement.
Add isStillQueued callback to verify the slot still holds the
originally captured command (STA-4876).

NeilandBrennan c92f394cde fix(pty): delete the reply-withholding scheduler (#15578)
* fix(pty): answer a terminal colour query in its own turn

Root-cause follow-up to #15559, which stopped a CPR overtaking a deferred
colour reply but left the deferral itself in place.

Orca answers terminal queries by writing to the PTY master, which a line
discipline in ECHO copies straight back out as junk on a cooked prompt
(#12112). The guard was to withhold the write until an `stty` subprocess
proved ECHO clear — and forking is what forced the decision to be async.
Any deferral, however short, lets a reply written later in the same turn
overtake this one, so the async probe was the bug's root cause.

Read the bit synchronously instead. Linux and the BSDs redirect a
master's mode ioctls to the slave, so a `tcgetattr` on the master fd
node-pty already owns answers for the slave with no fork: measured 0.26us
against 2403us for the subprocess. With a verdict available inline, a
querying program that already cleared ECHO — every raw-mode prober,
including the colour probe behind the `gh auth login` report — is
answered in its own turn and can never be reordered.

The deferral stays for the genuinely cooked case, and the ordering
guarantee stays underneath it: hosts whose node-pty predates this patch
get no sync probe and fall back to the deferred path, which mixed
client/host versions make a live production path.

Reply routing is all-or-nothing: a payload needing neither containment
nor ordering stays on the host's own path, so a CPR answered during shell
startup cannot pass the daemon's post-ready flush gate and splice into
the buffered startup command.

Native side is fail-safe: a kernel that did not redirect would answer
from the master's own termios, whose ECHO defaults set, so the degraded
verdict is "echoing" — never a false "quiet". The JS half ships in the
pnpm patch while the binding needs a source build, so
ORCA_REQUIRE_NODE_PTY_ECHO_STATE=1 makes CI fail rather than silently
skip when it is handed an upstream prebuild.

* fix(pty): keep the flush ordered under synchronous re-entry

Three defects found in external review of the reply-ordering work.

node-pty delivers onData inside the master write, so a query can be
answered while the queue is mid-flush. `flushPendingWrites` spliced the
array off before writing, so that reply saw an empty queue, took the
same-turn path, and landed ahead of entries the loop had not written yet
— reproduced as 01, 99, 02, 03. It now shifts one entry at a time so a
re-entrant reply queues behind the rest, bounded by the length at entry
so a re-entrant push cannot spin the loop.

An overflow flush can re-enter as far as teardown. `answer` did not
re-check `closed` afterwards, so it queued behind a closed delivery,
returned true, and the reply was never written and never reported.

The payload router's ownership comment overstated its guarantee. The
`any` semantics are deliberate — returning false after a constituent was
already written would have the caller re-write the whole payload and
duplicate it into the child's stdin — so the residual mixed-failure drop
is now documented rather than implied away.

* fix(pty): delete the reply-withholding scheduler

Orca answered a terminal query by withholding the write until a probe
proved the slave's ECHO bit was clear. That was the wrong mechanism, and
it is now gone: replies are written in the caller's turn and their echo
is contained on the output side, where it always was.

Withholding never removed an echo. The wait was bounded and always ended
in a write, so the output-side projections were doing the work the whole
time — including the readline rewrite, which happens with the tty already
raw and which therefore no reading of the ECHO bit can predict. What
withholding did add was an asynchronous write path, and that is what let
one reply overtake another and land in the next program's stdin (#15559),
what produced a re-entrancy inversion inside its own flush, and what four
rounds of regressions have lived in.

The last thing it covered was the verbatim echo of a `stty -echoctl` tty.
That shape is now projected directly. It starts with ESC, so it is
matched only when complete and never held as a partial: holding it would
take a bare trailing ESC from the query parser and an expired hold would
release it raw, so a query torn at its own ESC would never be answered.
Complete-match-only is what makes the shape safe to project at all.

Measured on a real pty: a cooked-mode master write is both echoed AND
delivered — ECHO copies the bytes without consuming them from the slave's
input queue, so a program arming raw mode with TCSANOW/TCSADRAIN (libuv's
setRawMode, hence every Node agent) still reads them. Only a TCSAFLUSH
switcher discards it, which it does on every terminal, none of which
gates a reply on termios state.

Deletes the pending-write queue, the async stty probe, the poll budget
and probe rate limit, the deadline-driven flush, and the answer/
answerInOrder split. Replies now leave in call order by construction.
No packaging, native or CI surface is touched.

* test(pty): restore stty-probe coverage and pin the duplicate-query retry

Archaeology on how withholding got here, and what its tests were really
protecting.

Deleting the ECHO probe took four tests with it that were not about the
probe at all: they cover createSttyProbe, which the shell-readiness
line-editor probe still uses — in-flight sharing, the per-platform stty
flag, and transient-versus-permanent failure latching. Restored against
the line-editor probe, which is now their only caller.

Also pins the property that answers the one case an immediate write
cannot serve. A program that queries while cooked and then arms raw mode
with TCSAFLUSH discards the reply with the rest of its input queue.
Nothing can prevent that from the terminal side, and no terminal tries.
What matters is that such a program re-queries after its own timeout: the
ingress declines to answer an already-answered slot but forwards the
duplicate downstream, so the renderer's emulator answers the retry, by
which point the program is raw. The retry path is the recovery, not
withholding.

* ci(pty): keep the fish real-PTY test in the shell-contracts lane only

Reverting pr.yml to main dropped the exclusion for the fish query-reply
test, which this branch keeps, so it would have run in the sharded lane
as well. Restores it to the shell-contracts include list and the shard
exclude list, and drops the parallelism expectations for the deleted
cooked-querier suite and the echo-state env guard.

Neil c72a4eecdd refactor(shell): collapse the zsh wrapper to one .zshenv and a precmd hook (STA-4786) (#15391)
* refactor(shell): collapse the zsh wrapper to one .zshenv and a precmd hook (STA-4786)

Orca needs to run code after the user's own zsh startup files. It bought that by
keeping ZDOTDIR pointed at its own wrapper dir for the whole of startup and
sourcing each user file by hand -- four generated files per transport, with a
fake ZDOTDIR live while /etc/zshrc ran. That single decision is the root of a
whole bug family:

- /etc/zshrc assigns HISTFILE=${ZDOTDIR:-$HOME}/.zsh_history unconditionally, so
  history landed inside Orca's own dir (#11044), and an epilogue had to repair it.
- zsh's sourcehome() ignores ZDOTDIR once the shell is in sh/ksh emulation, so a
  user .zshenv or .zprofile ending in `emulate sh` hid every later wrapper file.
  The emulation degrade blocks and their forked $(emulate) probes exist for that.
- One wrapper dir shared by two installed builds could mix files from both, so
  every generated file had to redefine the helpers it called.
- The baked generation-time ZDOTDIR literal is unusable when a Windows-generated
  wrapper is sourced inside WSL via /mnt/c (#8003), so the runtime path had to be
  re-derived from %x.

The wrapper now hands ZDOTDIR back on its first lines and defers Orca's work to a
precmd hook that runs at the first prompt -- after .zprofile, /etc/zshrc, .zshrc
and .zlogin, every one of which zsh reads from the user's own directory exactly
as in an unwrapped shell. Each bug above stops being reachable rather than being
repaired, and their machinery goes with them: eight of thirteen exported blocks in
shell-templates.ts, both drifted discovery bodies (unifying them closes the
"reconciling the two is a follow-up" note the file carried), and the relay's
separate ORCA_USER_ZDOTDIR shape. Generated zsh drops from 819 lines across
twelve files to 143 in three.

Two things the design has to get right, both found by running it rather than
reasoning about it:

- Every function is defined ABOVE the source of the user's .zshenv. A user file
  ending in `emulate sh` puts the rest of the wrapper under sh parsing rules, and
  the first prototype died there with `parse error near '\n'` -- silently, leaving
  the pane unwrapped. Function bodies are parsed at definition time.
- ORCA_ORIG_ZDOTDIR is vetted, not trusted. The launch config only sets it when it
  resolved a usable dir, but a pane inherits its parent's environment too, so a
  stale value from an older build can arrive on its own and would point ZDOTDIR
  back at a wrapper dir. The ownership check Node applies now also runs in the
  shell, where that route is visible.

Orca also stops inventing a ZDOTDIR: where the user has none, ORCA_ORIG_ZDOTDIR is
absent and the pane ends with ZDOTDIR unset, as an unwrapped login zsh does.

Verified on real zsh over a real PTY -- necessary, because a precmd hook never runs
in a shell started with -c, so the existing `zsh -i -c` probes could not have
exercised this design at all. src/main/zsh-startup-hook-pty-harness.ts drives the
shell to a prompt and reports through a file rather than stdout, which a PTY echoes.

* test(shell): cover the relay variant of the zsh hook in a real shell

The relay writes its own variant -- no OSC 133, remote CLI bin dir instead of the
agent-teams shim -- and it had no live coverage. It used to carry a second ZDOTDIR
shape as well, which is how it drifted from the desktop template in the first
place; now the spec flags are the only difference, and this pins that.

* fix(shell): rebase the single-file hook onto content-addressed wrapper trees

#15285 landed content-addressed wrapper roots and a per-transport fileset module
while this branch was in flight. The fileset modules are now the single place the
tree is described, so 'only .zshenv' is stated once per transport and the
required-paths check follows from it rather than repeating the list.

* test(shell): point the mixed-build proof at the relay, the one fixed wrapper path

#15285 content-addressed the desktop and daemon trees, so two builds can no
longer write the same directory there and the scenario this file covers became
unreachable on those paths. The relay still writes a fixed ~/.orca-relay/
shell-ready, so that is where the hazard survives and where the proof belongs.

* fix(test): make the zsh PTY harness survive a startup that stops to ask

Two CI-only failures, both from driving a real PTY where the old probes drove a
pipe:

- A host whose global zshrc runs `compinit` over directories it considers
  insecure stops startup and ASKS. A pipe-backed `zsh -i -c` never saw the
  question; a PTY sits at it until the timeout. The harness now answers it.
  ZSH_DISABLE_COMPFIX does not help -- that is an oh-my-zsh convention and plain
  compinit ignores it, which I confirmed by reproducing the prompt locally.
- The PS1 line was typed at t=0, so on such a host the question consumed it as
  its answer. The harness now waits for the shell to fall quiet first, which
  also stops a slow prompt framework racing the same write.

Also merges a duplicate vitest import the native code-quality audit flagged.

* fix(test): stop the live-shell assertions assuming macOS host behaviour

Two of them hardcoded what my machine does rather than what Orca owes:

- LINEINIT was pinned to 'none'. A host whose global zsh config installs its own
  zle-line-init widget has one either way; the contract is that it looks the same
  wrapped as unwrapped, which the assertion beside it already states.
- The dropped-precmd_functions case asserted HISTFILE was no longer the scoped
  path. Whether the scoped value survives at all is the host's call: macOS
  /etc/zshrc overwrites HISTFILE so it does not, and a host with no such
  assignment keeps whatever the spawn env set. Now compared against an unwrapped
  pane given the same env, which is the real contract on both.

Also notes, where the emulation cases live, that they only discriminate on a host
whose system zshrc clobbers HISTFILE -- on CI's Ubuntu the load-bearing assertion
is ORCA_HISTFILE having been consumed.

* test(shell): re-pin the fixes the four-file wrapper was built for

Archaeology over the removed blocks: each existed for a bug, so each needs the
bug shown to be unreachable rather than just the code gone. Six restored or added,
each naming the change that introduced the behaviour.

- #8003, twice: the wrapper sourced from a relocated root, and from a non-ASCII
  (token-range) one. The old file baked its generation-time path in and had to
  re-derive the runtime one from %x to avoid using it; this one bakes nothing.
  Both runs assert ORCA_SHELL_FEATURES came back consumed, so 'the user's .zshrc
  loaded' cannot pass on a pane that never read the wrapper at all.
- #4667: user startup files must see their OWN ZDOTDIR while they run, or plugin
  and theme lookups resolve into Orca's dir. The old wrapper swapped ZDOTDIR
  around each source; this one never takes it away, and the values now have to
  match an unwrapped pane's.
- #1947: a user .zshenv that returns early.
- #15258: an inherited ZDOTDIR that is an Orca wrapper dir must be refused. CI
  proved this route is live -- the launch config only sets ORCA_ORIG_ZDOTDIR when
  it resolved a usable dir, but a pane inherits its parent's environment too.
- #11044/#11146: a nested Orca inherits neither cross-process channel and no
  ZDOTDIR of Orca's, which is what makes #11044's plain shape unreachable rather
  than repaired. Verified the child-env probe detects a real leak before trusting
  it to report the absence of one.

Neil d7a23c84a9 fix(pty): keep a CPR reply from overtaking a deferred colour reply (#15559)
A background-colour probe writes `OSC 11 ;? ST` then `CSI 6n` and reads
exactly one response, using the CPR as its sentinel: a non-OSC first
response means "unsupported" and it stops draining. #13309 routed live
cooked-echo-risk replies through the ECHO-probe deferral while CPR kept
the immediate path, so the CPR overtook the colour reply, the prober gave
up, and the stray `ESC ]` was left in the tty for the next program —
`gh auth login` died on it with an escape-sequence error.

Queue a reply that needs no echo containment behind ones that do, FIFO,
and only while something is actually deferred, so latency-critical
replies stay immediate on every other path. Windows is unaffected: only
posix-pty defers, so the queue is always empty there.

Also: an in-flight echo probe is already the write continuation, so
re-arming the timer for a queued reply would fork a second stty and throw
away the first verdict; and teardown now hands queued uncontained writes
to the pty best-effort instead of dropping bytes the caller was told were
sent.

Known scope limit, pinned by tests and tracked for follow-up: the
guarantee is FIFO among recognised query replies, not over every byte —
a reply coalesced with a keystroke, and ordinary typed input, still
bypass the queue. Both were unordered before this change too.

Neil 1b5cc00870 fix(shell): content-address shell wrapper trees so builds stop clobbering each other (#15285)
Every writer sharing a userData dir -- main's local PTY path, the daemon fork,
and the daemons of other builds that outlive the app that spawned them -- wrote
one fixed `shell-ready/` tree. Last writer won, and the guard only re-checked
that the files were present, never that they were this build's. A daemon whose
spawn env no longer agreed with the wrapper on disk kept launching shells it
could not read: the ready marker never fired and every startup command waited
out the full 15s timeout, silently, with restarting the app powerless to fix it
because the daemon outlives the app.

Measured 15.17s vs 1.10s once the tree matched. The five live daemons on the
machine this was found on spanned app versions 1.4.181-1.4.185, all from the
same installed app across auto-updates, so this reaches ordinary installs.

Name each tree after a hash of its contents, at
`<userData>/shell-wrappers/<hash>/shell-ready/`. Different bytes are a different
directory, so "present" means "written by this build" again. The hash sits above
the `shell-ready` leaf because ZDOTDIR self-reference guards match that exact
suffix. Nothing collects old trees: ~48KB each, a couple of MB a year against a
userData dir in the tens of GB, not worth an `rm -rf` on the spawn path.

Also publishes the resolved root to WSL over WSLENV `/p`, since the in-guest
script cannot derive a hash, and reports readiness failures to the daemon's
NDJSON log rather than a console the detached daemon discards.

Generated wrapper content is byte-identical; snapshots unchanged.

Neil ef788c80c7 test(terminal): assert wide-char buffer content across repaints (#15280)
* test(terminal): assert wide-char buffer content across repaints

The first reproduction for the Korean duplication asserted on the byte
stream a pty emits, and it passes on real Windows on both ConPTY
backends. The reporter's evidence says that is the wrong surface: their
copied text pastes doubled, so the corruption is in the buffer, and in
one run the command echo is doubled while that same command's output is
clean - text that was correct when it left the shell and went wrong
while being placed on screen. A redraw landing on the wrong cells emits
perfectly legitimate bytes, so no stream assertion can see it.

These assert buffer content instead, against a cell-level model of a
grid where one glyph spans two cells. The model shares no code with the
emulator, but its rules were chosen to match observed behaviour, so it
is a regression detector rather than a first-principles oracle - the
header says so rather than overclaiming.

The largest case is a cursor positioned onto the second cell of a
two-cell glyph, then erase-to-end-of-line, then rewrite, swept across
every row and column at widths 8 to 44. That is the only place a wide
character can be half addressed. Also covered: a whole row re-emitted
over wide characters, which is the shape a console redraw takes;
snapshot round-trip of a half-addressed buffer; and reflow across 148
width pairs, which is the resize the reporter uses as a workaround.

Nothing reproduces. The emulator blanks the orphaned half correctly at
every width and column, and reflow is lossless.

The two pty specs run in the existing Windows packaging job rather than
a new lane. A dedicated runner cost roughly four minutes, almost all of
it checkout and a native rebuild, to run thirteen seconds of tests, and
Windows minutes bill at double - the packaging job already installs the
same dependencies and already runs a Windows test step.

No production code changes. An earlier revision added an environment
variable to select the system ConPTY, and it is dropped: its only effect
would have been to let a user disable the fix for an earlier duplication
bug, it logged nothing so a support bundle could not confirm it took
effect, and the tests drive the backend directly without it.

Refs #15192

* test(terminal): share the wide-glyph predicate instead of copying its regex

The duplication detector carried its own copy of the range the grid
model already exports, so the two could drift and only one would be
updated.

* fix(shell): carry a WSL pane's shell across relay revive and stop forking to probe zsh emulation (STA-4682)

Two residuals left behind by #15236 and #15258.

Relay revive called resolveDefaultShell() and ignored the entry's shell
override, so a restarted relay handed the user a PowerShell pane where a
WSL one had been -- and with it the host default shell's history rather
than the worktree-scoped one #15236 injects on spawn. The override and
the requested distro are now serialized (optional fields; state from an
older relay still revives the default shell) and re-resolved through the
same allowlist a fresh spawn uses, so revive re-launches the same shell
with the same guest-visible HISTFILE and the same WSLENV carrier. A bad
override degrades that one pane instead of failing the whole batch.

The wrapper's three `$(emulate)` probes each fork a zsh carrying
everything the user's config has loaded, and since wrapping widened to
every zsh pane every pane pays for them. Each probe now sits behind a
fork-free option test that is true whenever `emulate sh`/`emulate ksh`
has run; the exact probe still runs when that test passes, so no answer
changes. Measured on zsh 5.9 / macOS: 9.97 ms/run unwrapped, 14.20 ms/run
wrapped, 12.27 ms/run wrapped after -- about half the wrapper's cost.

* fix(shell): harden the revive override path and silence the option probe on an exotic zsh

Readiness-review follow-ups on this branch.

- `[[ -o <name> ]]` prints "no such option" to stderr and returns false rather
  than aborting, so a zsh lacking one of the three Bourne option names would put
  that text in the user's pane. All three predate every supported zsh, so
  `2>/dev/null` is belt and braces -- but the belt costs nothing.
- Bound the WSL distro name revive replays into `wsl.exe -d <name>`. It is the
  one field this branch newly routes from untrusted serialized state into argv,
  and reviveEntry's stated job is to re-apply fresh-spawn bounds.
- Skip a pane whose overridden shell can no longer spawn instead of letting the
  throw escape the revive loop and cost every later entry its state. Skipping,
  not falling back to the host default shell: substituting a different shell is
  the defect the override exists to fix, and the args and history env are built
  for the shell that is gone. The worktree-removal fence throws before this,
  outside reviveEntry, so it stays a hard failure.

Neil 66a5e5d245 fix(shell): repair worktree HISTFILE in plain zsh panes via one positive feature channel (#15258)
* fix(shell): repair worktree HISTFILE in plain zsh panes via one positive feature channel

A plain zsh pane — no startup command, no agent overlay — was never wrapped, so
Orca's HISTFILE repair never ran in it. macOS `/etc/zshrc` assigns
`HISTFILE=${ZDOTDIR:-$HOME}/.zsh_history` with no check-before-set and runs
before any file Orca controls, so per-worktree history was a silent no-op for
every ordinary pane on the primary platform.

Wrapping those panes needs a way to say which wrapper features a shell should
turn on. That channel is one exported variable, ORCA_SHELL_FEATURES, carrying a
comma-separated positive allowlist from a closed set (history, markers, ready,
identity, overlay). The wrapper .zshenv reads it into a plain, non-exported
array and unsets it in its first executable lines, before the user's own
.zshenv — so the selection survives .zshenv -> .zprofile -> .zshrc -> .zlogin in
this process but physically cannot reach a child. There is no negative or
suppression variable anywhere; an absent or inherited value can only ever mean
fewer features. ORCA_HISTFILE is consumed and destroyed the same way, which
removes the root cause of #11146 instead of patching it.

All order-sensitive wrapper work now lives in one `__orca_shell_epilogue`
defined in .zshenv and invoked exactly once, from .zshrc for a non-login shell
and .zlogin for a login shell, with each feature an independent guard.

Selection is a pure function of spawn env and launch intent, so a pane wrapped
only for history gets no OSC 133 and is observably identical to the unwrapped
pane it used to be.

Generation is now fail-closed: wrapper files are written to a temp name and
renamed, every required path is verified non-empty, and ZDOTDIR is only set when
that holds. Previously a failed write still pointed ZDOTDIR at an empty dir and
the user silently lost their entire zsh config.

Orca also recognised only its own `*/shell-ready/zsh` dir shape when deciding
what the user's ZDOTDIR was, so being launched from any other terminal that had
hijacked ZDOTDIR captured that as the user's config dir. Ownership is now
established positively — a stamped marker file, or Orca's own dir shape for
wrappers written by older builds — and an inherited ZDOTDIR holding no zsh
startup file is ignored. No vendor is detected by name.

* fix(shell): make the zsh epilogue option-proof and stop history widening relay wrapping

Review follow-ups on the feature-channel PR.

- `emulate -L zsh` as the epilogue's first statement. It runs after the user's
  own config, so `setopt no_unset` made the precmd_functions append a fatal
  error that returned from the whole function (no ready widget, ZDOTDIR left at
  Orca's wrapper dir), and `setopt ksh_arrays` made the 1-based feature
  subscript drop whichever feature is listed first.
- The `/etc/zshrc` HISTFILE repair is no longer behind the `history` guard: it
  undoes damage Orca's own ZDOTDIR caused, so it must also run for a shell that
  re-enters the wrapper after the allowlist was consumed.
- The relay keeps its own wrapping gate. Its .zshenv resolves the user's config
  dir from a ZDOTDIR Orca has already overwritten, so wrapping a remote pane
  just for `history` cost a relocated-ZDOTDIR user their whole shell config.
- A failed primary spawn no longer leaks the primary shell's launch env
  (wrapper ZDOTDIR + feature channel) into an unwrapped fallback pane.

* fix(shell): drop the relay wrapping gate and stop HISTFILE inheriting across Orca instances

The relay-specific gate added last round rested on a false premise:
main's hasOverlayRestoreEnv already included ORCA_REMOTE_CLI_BIN_DIR, and
ssh-pty-spawn-env sets that on every SSH pane whose session has a CLI
bridge — so ordinary remote zsh panes were already wrapped. The gate only
bit where remoteCliBridgeEnv is null (a host too old to report its
platform), where it silently dropped that pane's worktree history. All
three transports now share the features.length rule.

HISTFILE stays exported, so a newly wrapped pane handed the worktree
history path to every child, including a nested Orca whose panes then all
hit injectHistoryEnv's check-before-set and appended into the launching
worktree's file. Same class as the fish_history fix in #15195: recognise a
path Orca minted and drop it before the check, on the desktop, daemon and
relay injection paths and both history-disabled branches.

Also: run the epilogue from the wrapper .zshrc when zsh is in sh/ksh
emulation, since sourcehome() then reads $HOME/.zlogin and the wrapper's
.zlogin never runs; track fallback launch-env keys per attempt rather than
once from the primary; and guard the cross-file epilogue call so a wrapper
dir shared by two builds degrades quietly.

* fix(shell): make every wrapper file self-sufficient and retire the deleted marker vars from tests

- .zprofile/.zshrc/.zlogin each define __orca_resolve_user_config_dir. They
  called it on line 2 while only .zshenv defined it, so a wrapper dir written by
  two concurrently installed builds printed three "command not found" and
  skipped the user's entire zsh config. New live-shell test covers it.
- Retarget every remaining ORCA_SHELL_READY_MARKER/ORCA_SHELL_STARTUP_IDENTITY
  reference onto ORCA_SHELL_FEATURES, or delete it where the key is now dead.
- isOrcaMintedHistFile requires a leading '/', so a relative path of the same
  shape stays the user's.
- Drop an unused no-control-regex disable, and register the two real-zsh suites
  in the dedicated shell-contracts lane.

* fix(shell): stop the zsh wrapper colliding on REPLY and degrade under sh emulation

Widening wrapping from overlay/startup panes to every zsh pane turned three
latent wrapper defects into user-visible ones.

- The config-dir resolver used `REPLY`, zsh's shared scratch global, as its
  out-parameter. `typeset -r REPLY` in a user config made the wrapper's first
  executable assignment fatal, `typeset -i REPLY` silently resolved every path
  to 0; both left HISTFILE inside Orca's wrapper dir. It now writes an
  Orca-private `_orca_resolved_config_dir`, declared `typeset -g` so the
  rename introduces no `warn_create_global` noise. A new rule test fails on any
  generated wrapper file that writes a global outside Orca's namespace.

- The daemon dropped an inherited HISTFILE but never an inherited
  ORCA_HISTFILE, which now both wraps a pane the client scoped nothing for and
  re-exports another worktree's history path. The relay had the same gap on its
  isolation-off and revive paths. Both now mirror the desktop.

- A user .zshenv or .zprofile ending in `emulate sh` makes zsh ignore ZDOTDIR,
  so no later wrapper file is read and the epilogue never runs. Nothing can
  repair HISTFILE from there, so the wrapper now detects the emulation and
  hands the pane back unwrapped instead of leaving history somewhere invisible.

Also `typeset -g __orca_in_command` so the OSC 133 preexec hook prints no
warning under `setopt warn_create_global`.
