Brennan BensonandMerge Sim 8999a00281 refactor(native-chat): give each structured dispatch state exactly one meaning (#20133)
* refactor(native-chat): give each structured dispatch state exactly one meaning

`unknown` meant five different things. Only one of them was genuine
ambiguity.

A transport write that the provider's input pump never took is provably
undelivered -- which is what `rejected` already means. It was recorded as
`unknown` anyway, and a one-entry allowlist then existed solely to teach
Retry that this particular `unknown` was safe to re-deliver.

Collapsing that case into `rejected` deletes the allowlist and turns a
predicate into an invariant: Retry never re-delivers an `unknown`, with no
exception to reason about. The four states now each assert one thing --
`pending` written and awaiting, `accepted` the provider has it, `rejected`
provably did not happen, `unknown` genuinely cannot tell.

A fail-closed guard is the right default here because the asymmetry is
severe: refusing a legitimate retry costs the user a retype, while allowing
an illegitimate one sends the model a second copy of their message.

Also fixed, found while auditing every reader of `rejected`:

- The renderer printed `submission.reason` verbatim, so a broken pipe put
  the internal token `provider_write_failed: broken pipe` on screen in
  destructive red. The journal reason is unchanged -- it is the durable
  evidence and the transport-versus-content discriminator -- but the screen
  now gets copy that names the cause and says the message is safe to
  resend. Content rejections still show the provider's own words.
- The fallback copy "Message was not accepted" read as a content refusal.
  A null reason now yields "Message was not sent.", which asserts only what
  every rejection shares.
- A refused worker-start preamble threw a plain Error out of the dispatch
  path. It now throws `OrchestrationError('dispatch_preamble_undelivered')`
  so a coordinator can tell "we could not send it" from "we sent it and
  something else broke" without parsing prose. Retain/discard behaviour is
  unchanged; only the verdict's legibility improves.

Two behaviours improve as a consequence rather than by design: a provably
undelivered message no longer blocks conversation commands, and no longer
leaves the session reading as "working" in chat and in every session list.

Not addressed here, and named rather than implied: a message left `unknown`
by a dead child or a host restart still has no recourse but retyping. The
restart reconciler that would decide those on evidence is written and has
never had a production caller. Parking the refused entry instead would
reintroduce the head-of-queue wedge removed in #19863, so it is not an
option.

Note for whoever edits `journal-reducer.ts` next: it sits at 297 of its 300
counted lines. The next statement added there needs a split, not a shave.

* fix(native-chat): close two gaps review found in the rejection taxonomy

Both are narrow and both were real.

A journal written before a refused write became `rejected` still holds that
submission as `unknown` with the transport marker. The predicate this change
replaced excluded exactly that shape from provider-echo matching; the
state-only check that replaced it does not, so on replay such a row could
claim the echo of a later, genuinely delivered send of the same text and
attach the delivery to the wrong message. Fail-closed still prevented any
re-delivery, so nothing duplicated — but the wrong submission was credited.
Replay now excludes the legacy shape too.

And the content-versus-transport split had a third case neither side covers:
a local capacity refusal is neither the provider explaining itself nor a
frame that failed to leave. It fell through to the verbatim branch, so
`claude structured dispatch queue is full` reached the screen — the same
class of leak this change set out to fix, one reason short of being caught.
Internal reasons now get copy; only a provider's own words are shown as
written.

Each is pinned by a test that fails with its guard reverted and passes with
it restored.

* fix(native-chat): preserve dispatch refusal across clients

* fix(native-chat): rotate immediately rejected retries

* docs(native-chat): correct rejection taxonomy reference

* docs(native-chat): align mobile retry comment

* docs(native-chat): clarify unknown replay semantics

* fix(native-chat): keep a mobile send's operation id when delivery is unknown

Mobile released the retained operation id whenever a send came back
`unknown`, so the user's next send of the same text went out under a fresh
id. A fresh id has no ledger row, so the host treats it as a first delivery
and dispatches it -- even though `unknown` is the one answer that says the
provider may already have the message. That is the duplicate this branch
exists to remove, reintroduced on the client that has no outbox.

Which case that was matters. Mobile only ever sees `unknown` from ack-loss
(`isRpcDeliveryUnknown`: "the host may have processed it and only the ack
was lost"), because the mapper reported every `ok` result as `accepted`
without reading `dispatchState`. So the rotation fired exclusively where
delivery was ambiguous and never where it was provably refused, which is
the inverse of the rule this branch establishes.

Retaining the id is what makes a retry safe, and it costs no liveness:
`performSend` answers a second request under a recorded id from the journal
and never puts it back on the wire, so a reused id delivers when nothing
landed and replays when something did. Rotating can only ever add a second
copy. The retention stays bounded by the host's admission window, which
`retainStructuredSessionOperationId` already enforces.

`retryUnknown` goes with it: the host ignores it for delivery, and all it
does is skip the cached answer to re-read the same row.

Keeping the id exposes what the rotation was hiding, so fix that too: a
replayed `unknown` comes back `ok`, and mobile called it `accepted` and
cleared the composer as if the message had landed. `dispatchState` now
decides, in one pure function:

  accepted/pending  sent, and the id is spent
  rejected          provably did not happen and terminal in the reducer, so
                    reusing the id could only replay that rejection: spent,
                    and the next attempt is a first delivery under a new id
  unknown           keeps its id

Reading `dispatchState` at all is a pre-existing defect, fixed here because
the false "sent" cannot be removed without it, and scoped to the send path.
`mutate`'s rotation for prompt/option/cancel plans is untouched. The
rejection copy is the desktop's notice, so an internal reason
(`provider_write_failed: ...`) still never reaches a person.

Tests: the hook test that was flipped to assert a rotated id now pins the
opposite -- one id across an ack-loss and two `unknown` replays, each
reported `unknown` rather than `accepted`. The send fixture grew the durable
submission row a real host returns; without it every send test asserted
against a shape that cannot express the bug.

Brennan BensonandMerge Sim 027acb4efa fix(native-chat): settle a structured send on admission, not on the provider echo (#19863)
* fix(native-chat): settle a structured send on admission, not on the provider echo

Sending a message in structured native chat raised "Message delivery is
unconfirmed." with a Retry button on a message that had in fact been
delivered. Measured across 14 days of local journals: 44 of 173 delivered
sends (25.4%) tripped it.

The dispatch path wrote the message to the provider, then waited a fixed
10s for the provider to echo the message's uuid back. That echo is emitted
when the provider STARTS the turn, so a message queued behind a running
turn cannot be echoed until that turn ends. Echo latency is bounded by the
previous turn's duration, which is unbounded -- one send took 105 minutes.
The 10s constant sat at the p75 of real echo latency, with the slowest
clean send at 9.76s, a margin of 0.24s. No constant can work: the wait was
measuring the wrong event.

The false banner was not cosmetic. It invited a Retry, and Retry bypassed
the operation ledger to redeliver. One message reached the model five times
through that path.

Dispatch now returns as soon as the transport write completes and writes no
dispatch row; the submission stays `pending`, a neutral state, and the
provider's echo settles it `accepted` through the late-settlement channel
whenever the turn ahead of it ends. Delivery doubt is reachable only from
process facts -- a refused write, a dead child, a dead host -- never from
elapsed time.

Retry re-delivers only where the recorded reason proves the message never
reached the provider. The list is deliberately fail-closed: refusing a
legitimate retry costs the user a re-type, while allowing an illegitimate
one sends the model a second copy of their message. A refused entry now
leaves the outbox with an explicit notice instead of parking at the head,
where it would have wedged every message queued behind it.

The send-response classification moves to a pure module beside the existing
outbox reconciler, so both writers of an entry's state now live together and
the decision is unit-testable rather than reachable only through the hook.

Scope and known gaps:
- Codex carries the same 10s stopwatch. It has no late-settlement channel,
  matches waiters by queue order rather than identity, and has no waiter
  lifecycle at all, so there was no safe subset to land here. A marker
  constant records the debt and deletes itself when that lands.
- A message refused re-delivery loses its standing delivery notice and
  leaves only a transient error line. A passive "waiting to be accepted"
  affordance is the follow-up.
- The restart reconciler that would decide a dead child or a dead host on
  evidence rather than refusing them is fully written and has never had a
  production caller. Wiring it is the next change, and it removes the
  re-type cost above.

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.

* fix(native-chat): reset outbox error in render on session switch

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
