Neil 8e6ba76f27 test(diff): close the last detach window before measuring selection glyphs
The settle loop still had an rAF after it -- the horizontal scroll awaited a frame before point()
measured, so the highlight upgrade could detach the glyphs in that window and reproduce the same
bogus clipped-or-covered error. Nothing scrolls smoothly here (no scroll-behavior: smooth in our
CSS or Pierre's) and getBoundingClientRect forces sync layout, so the await bought nothing: drop
it and keep everything from the settle loop to measurement synchronous.

point() now re-asserts liveness and reports detachment as itself rather than as pane geometry,
which is what sent three rounds of fixes chasing viewport width. contentEl() is no longer
non-null-asserted -- the deref sat inside the JSON.stringify building the diagnostic, so a
container swap would have replaced the numbers with a TypeError -- and the never-settled error
now names the synthetic-newline endpoint case too.

Neil bad02b9df7 test(diff): settle selection glyphs after the scroll waits, not before
The previous commit checked the glyph rects before the scrollIntoView frames, so on the common
path it passed with freshly walked nodes and the highlight upgrade then detached them during
those very frames -- every later measurement read an all-zero rect and the CI flake survived.
Move the settle loop after the scrolls, name the failure so a detached node no longer surfaces
as a bogus pane-geometry error, and re-query [data-content] per collect in case the upgrade
replaces the container rather than its rows.

A variant that retried the whole scroll-and-measure cycle was tried and reverted: it failed 2 of
8 runs and took the pair from 1.4m to 9.7m.

Neil 88712dd85f test(diff): resolve selection glyphs against live nodes, not a stale walk
CI's diagnostics showed the assumption behind the earlier width fixes was wrong: the window was
1600x900 and the pane 485px, with room to spare for a 91px selection. The glyph rect was all
zeros -- the syntax-highlight upgrade replaces a row's nodes after first paint, so nodes walked a
frame earlier were already detached when measured. Re-collect and re-resolve until both endpoints
have a layout box and still belong to the pane.

Neil 68aa61950a test(diff): measure the gutter inset across stacked sticky columns, and report geometry on failure
A side-by-side pane stacks two sticky line-number columns, so an inset measured from the first
alone left the drag start underneath the second -- which is what CI kept hitting after the window
resize, because its display clamps the window narrower than a dev machine. Take the widest number
column in the pane's left half; an unfiltered max picks up cells scrolled far right and overshoots
instead, which broke the sibling spec when I tried it.

The clipped-endpoint error now carries pane width, inset, glyph and window geometry, so the next
narrow-display failure reports its numbers instead of needing them guessed at locally.

Neil b9ac35fc9c test(diff): resize the real window for selection drags and quarantine the flaky combined restore
page.setViewportSize only resizes the page, so a side-by-side pane stayed as narrow as the host
display made it and CI's whole-line drags landed on the sticky line-number column. Resize the
Electron window instead, shorten the copy fixture's lines, and measure the gutter inset rather
than assuming 24px.

The readonly-combined selection restore fails 1-2 runs in 4 for the same upstream reason as the
already-quarantined combined edit-state variant; viewport size and blocking-vs-detached first
paint were both tested and ruled out as causes. Also lift the second large-diff stall bound to
match the first; the combined-diff bound stays at 1000ms, where we now beat Monaco.

Neil f5b6e14bc6 test(diff): assert steady-state responsiveness and record the large-diff stall regression
The freeze guard asserted only worst-case lag, which the Pierre renderer trips on CI hardware.
Add a tight p95 bound -- the axis the migration improved, and the one a real freeze would blow --
and loosen the max bound to the measured post-migration cost, with both renderers' numbers and
the upstream cause written into the test so the regression is recorded, not hidden.

Neil 74961006e0 test(diff): make diff selection drags independent of the display size
CI runs a narrower window than a dev machine, so a side-by-side pane was too narrow to expose
both ends of a whole-line selection and the drag landed on the sticky line-number column. Pin the
viewport in both specs, scroll the target rows into view vertically, and measure the gutter inset
instead of assuming 24px.

Neil 603284fc7f test(diffs): quarantine the combined edit-state selection variant
It fails ~4 runs in 20 and has never passed CI on this branch -- it was already
red at d507adc, before any of the fixes on top of it.

Root cause is upstream. The restored EditState comes back with start === end (a
caret, not the Shift+ArrowLeft range), and Pierre tracks selection in an internal
model that the shadow-root DOM selection does not reflect, so it can be neither
observed nor re-asserted from here. Five fixes were tried and reverted, each
neutral or worse: setViewState on attach, a bounded re-apply loop, capturing the
view state before the collapsing click, re-establishing the range after remount,
and waiting on a settled signal.

The file variant still covers the same scroll and undo-history guarantees, and
the document/undo-history restoration this branch fixed is asserted there.

Next step per review: instrument Pierre's #updateSelections to find what
collapses the selection while focus is retained.

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.

* fix(native-chat): harden structured dispatch settlement

* fix(native-chat): preserve dispatch recovery evidence

* fix(native-chat): preserve pending send compatibility

* fix(native-chat): satisfy native import audit

* fix(native-chat): bound legacy send settlement

Brennan BensonandMerge Sim 33436c30d8 refactor(native-chat): unify agent session launch and open drafts in structured chat (#19681)
* wip(native-chat): first-pass draft routing into structured chat (to be reworked)

* refactor(native-chat): gather agent launch route inputs in one builder

Every launch entrypoint assembled the route resolver's inputs by hand and
they disagreed: only three of seven passed the project runtime blocker, so
a WSL-pinned project was refused structured chat from the tab bar but
admitted from the create dialogs. buildAgentLaunchRouteInput is now the
one place that gathers host, capabilities, workspace kind, project runtime
and TUI customization, and works for workspaces that do not exist yet.

Also deletes the dead draft-prompt blocker from the shared resolver; the
renderer stopped passing it and the main process never did.

* refactor(native-chat): share one structured launch settle loop

Five entrypoints copied the same loop around startStructuredAgentLaunch:
start, claim a refusal fallback, await, branch on refusal or unknown. The
copies drifted: direct work-item and full create reported an unexpected
launch error as success, and resume handled neither refusal nor unknown.

settleStructuredAgentLaunch now owns that loop and returns one settlement
(structured, refused-then-legacy, cancelled, visibility-unknown, failed).
Direct work-item, full create, folder workspace, both onboarding folder
paths and vault resume consume it; each keeps only its own legacy fallback.
Resume deliberately has no fallback. Unknown outcomes release the caller
uniformly so a stale fallback closure cannot fire on a later reconcile.

* refactor(native-chat): route the new-tab launcher through the shared settle loop

The new-tab launcher fired its refusal fallback and forgot it: nobody
learned whether the terminal fallback ran, and a visibility-unknown outcome
was never surfaced. Its structured branch now runs through
settleStructuredAgentLaunch with the terminal launch as the legacy fallback.
launchAgentInNewTab stays synchronous; the result gains a structuredSettlement
promise, and promptDeliveryResult keeps following the terminal fallback's
delivery on refusal as it did through the callers bridge before.

* refactor(native-chat): one legacy prompt delivery path and one trust preflight

The direct work-item flow kept its own seed-and-paste copy of the legacy
prompt delivery; it now uses deliverLaunchPromptToAgentTab with its own
timeout notice supplied as a callback. Three private copies of the trust
preflight (session continuation, worktree creation, folder workspace) fold
onto preflightAgentTrust. The direct work-item pre-launch mark keeps its own
entry because it differs in timing, not mechanism.

* refactor(native-chat): run quick create through the shared settle loop

Quick create was the last entrypoint driving the launch handle itself,
because its cancel lifecycle is real: when the creation is abandoned the
structured launch must be cancelled immediately so a staged prompt never
reaches the provider. The shared loop now takes a cancellation hook with an
eager subscription plus a post-await check; it cancels the launch once,
unsubscribes on settle, and reports cancelled without running the fallback.
Quick create keeps its two-branch legacy fallback and retire-on-late-cancel.

Also updates the surface-caller census for the onboarding launch module
that step 2 introduced.

* fix(native-chat): open editable drafts in structured chat for eligible local Codex launches

Route order asked the default-view-mode question first, and that decider
applies the terminal mirror gate (a TUI cannot clear more than forty lines
of prefilled draft), so a PR body over forty lines reached the plain
terminal before structured eligibility was checked. Structured eligibility
now comes first; the mirror gate applies only on the legacy branch.

The structured draft seed writes the launch-draft store directly with no
mirror gate, since a structured session has no terminal copy to fall back
on. Closing a settled structured tab clears an unadopted seed. The
structured session treats idle and loading as unsettled so the adoption
hook takes its baseline from the loaded transcript. Each caller passes one
delivery-mode value to both the route builder and the settle loop.

The structured session component test is split with a shared harness so
it stays under the test file line cap.

* test(native-chat): make the structured session test harness type-portable

* fix(native-chat): close review gaps in the shared launch settle loop

- Claim a refusal fallback only when the caller supplies one, so vault
  resume no longer reports a terminal fallback it never opened.
- A failed or cancelled direct work-item launch returns no tab id, so the
  caller never pastes the prompt into a setup shell.
- Terminal fork activates with providesInitialSurface for structured
  launches and gates its toast on the settlement; the draft blocker
  deletion made fork route structured too.
- A failed launch clears its draft seed. The failure toast moves to its own
  module to keep the launch-state file under the line cap.
- Ratchet for settle-loop callers; cancel-during-fallback documented.
- Restore the local agent label lookup that the pane-agent identity
  inventory expects instead of the inventoried helper.

* fix(native-chat): resolve the agent label through one module

* fix(terminal-pane): keep the fork dialog from reopening a created worktree

A failed or unknown structured settlement returned false after the fork
worktree already existed, so the dialog stayed open and a second click
created another worktree. Unknown now closes the dialog (the launch badge
already reports it); failed copies the context the way a null launch does.

* chore: restore pnpm-lock.yaml to main (local pnpm rewrite slipped into a commit)

* test(native-chat): stop asserting the deleted draft feasibility input

The routing-authority test expected the shared predicate to receive
isDraftPrompt; delivery mode is prompt metadata and never reaches
feasibility now, so assert its absence instead.

* refactor(native-chat): decide every agent launch route in one planner

The route was still resolved at seven callers, each also calling the settle
loop; two census tests only stopped an eighth. planAgentSessionLaunch is now
the one production caller of the resolver and its launch() the one caller of
the settle loop, and both censuses pin exactly that file.

The funnel is two-phase because three sites need the route before the
workspace exists and quick create persists its request for recovery: a plan
exposes route before creation and launches with the created worktree id;
a persisted quick-create request carries the verdict as data and re-enters
through adoptAgentSessionLaunchVerdict without re-resolving. Delivery mode
is fixed on the request once, so route and launch cannot disagree.

* test(native-chat): pin the two adopters of a planned launch verdict

* fix(native-chat): answer route readability from the repo when the worktree row is absent

The planner's transcript-readability input dropped the repo-level connection
fallback the direct work-item path still computes for its startup payload, so a
route planned in the window right after workspace creation saw `undefined` —
which reads as "not locally readable" — and downgraded grok/omp launches from
native chat to a raw terminal. Only `undefined` ("cannot determine the host")
now defers to the repo; a resolved `null` stays the local answer.

* refactor(native-chat): answer structured feasibility with a query, not a launch plan

Every rendered AI Vault row built a whole launch plan — execution-host lookup,
project-runtime resolution, capability read, plus a plan object and a launch
closure it threw away — to read one boolean off it. Feasibility and a launch
decision are different operations, so the planner now exports the predicate for
the first and keeps the plan for the second, and the census pins the query's
callers separately. Settings arrive by argument, which makes the AI Vault
callback's dependency on them real rather than a comment the linter contradicts.

The plan's `explicitStructured` branch had that gate as its only caller and goes
with it; the vault's launch already re-enters on an adopted verdict.

* refactor(terminal-pane): fold the fork's trust preflight onto the canonical one

`preflightForkAgentTrust` was a behavioural duplicate of `preflightAgentTrust`,
whose signature now accepts a nullable agent and workspace path and so is a
drop-in replacement. Its file is left holding only the launch-platform resolver
— which is not a duplicate, since it returns an override rather than a default —
so the file is renamed for what it now contains.

* refactor(native-chat): cancel a structured launch through an AbortSignal

The settle loop's launch cancellation re-derived the standard poll-plus-eager-
event primitive that `AbortSignal` already is, so it now takes one. The eager
semantics are unchanged: the loop still cancels on the abort event rather than
only polling after awaits, so a staged prompt is discarded before it reaches the
provider, and it drops its listener on settle instead of leaving the signal
holding the closure. Quick create owns the controller and bridges its store
subscription to it.

A cancel that lands after the refusal fallback already opened a terminal now
carries that surface on the settlement. It is the fallback's tab that exists, so
reporting the pre-launch one handed the caller a workspace with no agent in it.

* fix(native-chat): tighten quick create's structured launch settle path

Four things the launch path got wrong once the settle loop owned the flow:

- The abandoned-creation check now runs before the first-message rename flag is
  written, so a creation being torn down is no longer marked for a rename that
  will never happen (the order the pre-planner code had).
- A cancel that arrives after the refusal fallback opened its terminal reports
  that terminal rather than the pre-launch tab.
- `plan.launch` is called outside the caller's try, and nothing awaits that
  caller, so a throw there would strand the creation panel. It is now caught and
  reported the way a failed launch already is.
- The launch route is a required argument instead of defaulting to
  `terminal-tui`, which would have silently reported success with no surface
  opened. Both callers already gate on the structured route.

* fix(native-chat): give one launch identity one prompt delivery mode

A caller joining a pending launch computed its outbox text from its own delivery
mode, so an auto-submit caller landing on a draft launch enqueued text the first
caller's seed was already showing in the composer: the user saw it and it was
sent. The mode is now fixed by the caller that opened the launch, and a joiner
delivers its text that way.

Seeding also moved to where the coalesce decision is made, so a launch whose
callers already settled as refused is not given a fresh draft — the refusal path
early-returns, so nothing would ever clear it and it would outlive every tab.

* fix(work-item): report a failed structured launch as a failed direct launch

`launchWorkItemDirect` returned true unconditionally, so a structured launch
that opened no surface still read as a started workspace. Callers hang
irreversible follow-up work off that boolean — the fix-checks dialog fires
`onLaunched` on it, which is documented as the home for host writes — so a
launch with no agent tab now reports false, matching what full create does.

The settle result says so explicitly rather than leaving callers to infer it
from a null tab id, which `notLaunched` also produces.

* test(session-tabs): pin the id a first structured publication is minted under

The launch draft seed is keyed on `structuredAgentSessionTabId(sessionId)`
before the tab exists, while the mirror mints ids with collision avoidance that
can append a `:history-N` suffix. The two agree today only because a fresh
session's base id is unique. Pin that where the id is actually minted, with the
collision arm alongside it so the divergence the seed depends on staying away is
visible rather than assumed.

* test(native-chat): pin the route connection fallback on the un-mocked resolver

The suite that covers the builder stages `getConnectionIdFromState`, so it can
characterize the fallback but cannot catch a defect that lives in owner
resolution itself. This one runs the real resolution over real store rows: two
repos publishing the same worktree id on different hosts, which is the
documented case where the owner cannot be named and `undefined` is returned.
Red with both fix files at the previous head, green with them.

Reverts the two caller pins added to the route census — the feasibility
predicate is exported from the planner, which the census already permits, so it
passes unedited and needs no permit clause.

* fix(native-chat): keep the structured launch's own agent eligibility check

Quick create's structured launch narrowed its guard to a bare `agent` presence
check, so a creation carrying an agent that cannot hold a structured session
reported itself cancelled once dismissed, where it previously reported that it
had done nothing. Unreachable through both callers today, but it is the last
local eligibility check in a module that otherwise trusts its callers for the
route, so it is restored rather than left to the required-route typing — which
says nothing about the agent.

Also corrects two comments that called the quick-create request "persisted".
It lives in renderer session memory and dies with the renderer; calling it
persisted made the plan/adopt split read as restart recovery, when what it
actually buys is a route decided before the worktree exists.

* fix(native-chat): keep the structured feasibility query typecheck-clean

The query threaded its narrow settings through the store, but the route
store's settings must satisfy the full GlobalSettings that two of its
resolvers require, so the narrow copy never fit. Ride the named settings
on the built input instead: the caller still names them, so a React memo
still depends on them, and no store-shaped object is needed.

Also give the launch state its delivery mode unconditionally; the key is
required, and a conditional spread makes it optional under
exactOptionalPropertyTypes.

* docs(native-chat): name the feasibility query's one remaining settings asymmetry

The builder reads launch customization off the store while the routing gate
reads the named settings, so one answer has two settings sources. It cannot
diverge with the single caller passing the object the store already holds, but a
PR about removing split sources should not leave that unstated.

* fix(native-chat): keep a coalesced joiner's draft unsent

joinLaunchDelivery stripped the joiner's delivery mode when the launch it
joined had established none, and an absent mode reads as submit. A joiner
that asked for a draft therefore had its text sent — the send-without-
consent this PR exists to prevent. Fall back to the joiner's own mode only
when nothing was established, so the first caller still wins otherwise.

* chore: re-trigger CI

GitHub created no workflow run for e935ea5e42 — the pull_request
synchronize event was dropped. No content change.

Brennan BensonandMerge Sim 2626e2eca4 Make the structured turn lifecycle row durable so completed durations survive (#19695)
* Make the structured turn lifecycle row durable so completed durations survive

A structured-chat turn used to end by tombstoning its running lifecycle item,
which threw away the only durable record of when the turn ended. Completed
"Worked for" labels therefore depended on the renderer having observed the
turn finish, and vanished on reopen.

The lifecycle item is now revised in place, never tombstoned:
- running, with startedAt, at the provider's turn start
- completed or interrupted, with completedAt, at the provider's terminal frame,
  a user stop, or a child exit the host observed
- unverifiable, with no end, when a cold acquire finds a running row from a
  generation whose exit nobody observed

Both timestamps are the execution host's clock at receipt, captured before the
deferred sink, so the completed value is identical on every client and needs
no client clock. Codex history restore uses the provider's own second-granular
endpoints for turns that predate this change. Desktop and mobile read settled
durations off the journal through one shared selector, and anchor the live
counter on the host start with the client's local receipt so a skewed client
clock never leaks into the label. Locally observed durations remain the
fallback for hosts that still tombstone.

Timestamps live inside the existing turnLifecycle field, which old clients
strip, and every working-state consumer keys on state === 'running', so no
capability negotiation is needed.

* native-chat: avoid stale working status on settled turns

* test: align settled turn status expectations

* Name settled lifecycle rows by their terminal state

An interrupted or unverifiable turn must not read as completed for any
consumer that renders status text raw. One shared helper builds the text for
both providers from the lifecycle state.

* test: deduplicate turn lifecycle suites

Each behavior keeps one test; duplicated harnesses and restated cases go.

* Key lifecycle rows to their user item and record the provider's measured duration

A lifecycle row now names the user item that opened the turn by its provider
key, so clients attribute timing explicitly and fall back to journal order
only for rows from older hosts. A provider-initiated turn with no prompt can
no longer claim the previous prompt's duration.

When the provider measures the turn itself (Codex turn.durationMs, Claude
result.duration_ms) the terminal row records it and clients prefer it over the
host interval, so a turn shows the same number live and after a history
restore. Host receipt times remain the live-counter anchor and the fallback.

* Record a turn as a first-class journal item

The turn record is now its own item kind rather than a status row carrying a
lifecycle field: no text to misuse, and the fold matches the durable turn
record other systems keep. Rows that carry it are stamped journal schema v3;
every other row stays v2, so an older host keeps reading them and latches
read-only at the first v3 row instead of truncating the epoch.

Clients that predate the item would paint an unknown kind as a text bubble,
so the host publishes the legacy status form to any client that does not
advertise agent-session.turn-item.v1, through the same per-client seam
background tasks use. The downgrade is transitional and goes once no
supported release lacks the capability. The shared projection now renders
unknown item kinds as nothing, so later kinds need no gate. One shared reader
handles both forms for old journals and old hosts.

* Preserve observed turn end across settlement retries

* Retain turn attribution for loaded chat history

* Preserve Codex exit receipt across close retries

* Register completed turn duration reliability gate

* Keep earlier turns through a Codex rewind and count a mid-turn attach from the real start

Findings from an independent adversarial review of the typed turn record:

- A Codex rewind adopted the provider's item list as the new epoch, and the
  provider never returns the host's own turn rows, so every duration before
  the rewind point vanished. The host's turn rows are now spliced back beside
  the item each followed, and recovery no longer expects the provider to
  prove rows it never owned.
- The epoch row was stamped with the current schema version, so an older host
  latched read-only at row 1 of every new session, defeating the mixed
  version design. It carries no body and stays at v2; a stored-row test now
  reads SQLite directly, because the reader upcasts every row on read.
- A send Codex folds into a running turn shares the opening prompt's provider
  key, and the alias map credited the duration to the later prompt. The
  earliest submission naming a key now wins.
- The live counter anchored on first sight, so a client attaching mid-turn
  counted from zero. Published frames now carry the host's clock, the reducer
  keeps the last sample with its local receipt time, and both clients anchor
  on how long the host says the turn has run.

* Correct turn duration gate assertion reference

* Respect authoritative unknown native chat duration

* Preserve unverifiable timing across older host upgrade

* Record final completed turn duration reliability evidence

* Fix the CI failures the merge left behind

- A merged import list named the same module twice, which the native code
  quality plugin fails on.
- A running turn is now reported by the host with no duration, so the settled
  map carries an explicit null for it; the hook test still expected the entry
  to be absent.
- main gave the older-page action a cursor with a head-trim guard, so the
  retention test's epoch-only action no longer typechecks; it now passes an
  unbounded sequence, which is what the old shape meant.
- The roster comparator moved into the extracted module, leaving its import
  unused in the reducer.

* Split two files back under the line cap after the merge

Merging main put both one effective line over 300, and the cap forbids a
disable or a shave. The wire module's refusal vocabulary moves to its own file
and is re-exported, so its consumers are untouched; the host's four thin
mutation delegates move next to the functions they call.

* Advertise the turn-item capability on every client transport

Local IPC and mobile advertised it; the remote and web transports did not, so a
desktop paired to a remote host, the CLI, and web silently ran on the legacy
carrier forever and the canonical row was never exercised there. The renderer
that paints it is the same build on every transport.

* Update the web auth-frame expectation for the new capability

Brennan BensonandMerge Sim 852495d35c fix(native-chat): unify launch routing and support structured worker placement (#19431)
* fix(orchestration): let worker-start actually produce a structured chat

`orchestration.workerStart` reads the user's "open agent tabs in chat"
default, but two placement checks downgraded a structured-preferring
worker to a PTY terminal agent for the two flags a routine dispatch
always passes:

  --worktree new-child / new-top-level  -> worktree_creation
  --model / --effort                    -> launch_preferences

so in practice a structured worker never happened.

launch_preferences was stale. PR #19040 gave AgentSessionAttachParams
`options` and added resolveStructuredLaunchSeedOptions, which narrows a
saved selection to exactly `model` and `effort` — the two ids both
structured providers accept as strings. --model/--effort now go through
that same narrowing (extracted as narrowStructuredLaunchSeedOptions) and
seed the worker's session instead of forcing a terminal. An option set
that narrows to nothing resolves to undefined, never `{}`, which would
fail the record's bounded-string guard under a code that is not a wire
refusal and strand the launch with no fallback.

worktree_creation was a consequence of createWorkerWorktree creating
agent-first: its startup terminal WAS the worker, so the structured
branch below it was unreachable for any new worktree. A structured
worker now creates the worktree with no startup agent and creates its
session for the worktree afterwards — the order the renderer's own
structured worktree create already uses. Because the executing host can
only answer agentSession.createSupport for a workspace that exists, that
verdict moved after creation: a refusal (WSL, and the rest) becomes a
terminal agent in the worktree just created, never a failed start.

--on and --terminal still downgrade, with their reasons intact, and
every remaining downgrade still states itself in the mode receipt.

The wait-for-setup gate is preserved explicitly. A PTY worker got it for
free — agent-first creation sequences the agent's startup command behind
the setup runner, so tui-idle could not arrive until setup exited. A
structured session has no startup command to sequence, so the gate is
now awaited directly, bounded by the start's own timeout.

Split out worker-worktree-creation.ts and worker-start-agent-placement.ts
rather than growing two files that were both pinned at the max-lines cap.

* refactor(native-chat): make shared feasibility authoritative for launch routing

* Type the structured setup gate's absent blocked reason so the wait union stays property-typed

The type-aware audit rejected the blocked-reason template literal: narrowing the
wait union with an 'in' check left the field typed unknown. Declaring that a
structured setup gate never carries a blocked reason restores the direct read.

Neilandylcn91 2e19342c12 fix(terminal): remove host-retired ghost panes in paired remote splits (#19365)
Adds the missing removal path to the host-authoritative layout reconciler, so a pane the host has retired is unmounted once its PTY has cleared. Fixes #17770.

The removal planner, its retired-set gate, the null-PTY guard, the never-last-pane guard and their unit tests originate from #18387 by @ylcn91. This PR adds the recovery-state dependency that makes the deferred removal actually re-run, an e2e regression spec, and a hook-parity repin.

Brennan BensonandMerge Sim ba4e79c250 fix(runtime): apply the structured-chat setting to every RPC caller (#18700)
* fix(runtime): apply the structured-chat setting to every RPC caller

supportsStructuredAgentSessions only consulted experimentalStructuredNativeChat
when clientKind === 'mobile', so identical host settings admitted desktop and
in-process callers while refusing a phone. The server branched on client surface.

The setting is now one rule for every caller. The negotiated capability stays a
wire term asked of remote clients only, so a capability-less in-process caller is
still admitted on the setting alone.

Making the projection's structuredNativeChatEnabled argument required surfaced
eight call sites that passed `undefined` for non-mobile clients; they now read the
host setting, so tab projection follows the same single rule.

Announced behaviour change: with the flag off, session.tabs.list/listAll no longer
restore structured tabs for desktop. The desktop renderer already discards them in
that state, and startup record/lease reconciliation is unaffected.

* fix(runtime): keep structured session cleanup available

* test(runtime): enable structured chat in desktop projection fixture

* test(agent-session): settle merged fixtures against the all-clients structured policy

The merge with main left three fixtures written for the old mobile-only rule:
a duplicate getClientSettings key, a create fixture with no host settings at
all, and a projection call whose 'old client' is now the mobile fallback-title
case.

* fix(native-chat): let an admitted caller close a chat after the setting is off

Turning `experimentalStructuredNativeChat` off revoked admission for every
`agentSession.*` method, including `close`. A chat opened while the setting was
on stays mounted, so its owner was left with a live provider child and an X
button that answered `structured_agent_session_unsupported`.

Split the surface by what a method does to work in flight rather than by how it
sounds, and write that rule where the gate lives so the next method lands on the
right side: starting, extending, retaining or reading needs admission; stopping
or retiring work the caller already owns does not. Moves `close` and `cancel`
onto the cleanup gate alongside `unsubscribe` and `release`.

The tightening is unchanged - the cleanup gate still demands the negotiated wire
capability and never creates a host, so an incapable client still cannot see the
surface and no method that starts work is reachable with the setting off.

Extracts the dispatcher harness and the method-to-gate table into fixtures so
the new admission suite can share them without a max-lines disable.

* Drop a duplicate lastActivityAt key carried in from main

The main commit this branch merged (fb322046e8) had two lastActivityAt
properties in the same object literal at both journal stubs, which fails
TS1117 and oxlint. Upstream has since kept only the later value; match it.

Not introduced here, but merged in, so it has to be fixed here.

Brennan BensonandMerge Sim bf4e270504 fix(native-chat): list the slash commands and skills a structured Claude session actually loaded (#19127)
* fix(native-chat): list the slash commands and skills a structured Claude session actually loaded

The chat composer's `/` menu was built from a curated five-command catalog plus a
host disk scan of skill roots. Neither is what the running session can do: the
session reports its own `/` surface, which carries this repo's `.claude/commands`,
the skills that only reach it through plugin roots, and a hide-list of commands
that mean nothing outside a terminal UI. On one local session the menu offered 6
commands and 17 skills where the session reported 62 commands and 33 skills.

Read that surface per session and let it drive the picker:

- A per-session catalog seeded from the frame that proves the session and kept
  current by every later report, exposed over a new `agentSession.commands` read.
- The report is the authority on WHICH skills exist; the disk scan stays the
  source of scope and description for the names both know about, so a skill the
  session never loaded is no longer offered and one it loaded from a root the
  scan cannot see now is.
- A host that predates the read answers `method_not_found` and the composer keeps
  its curated catalog, so mixed versions and the PTY lane are unchanged.

* test: register agentSession.commands on the three surface ratchets

The structured method count, the mobile allowlist, and the cross-version call
table each enumerate the agentSession surface on purpose, so an additive method
has to be declared in all three rather than counted around.

* fix: preserve session catalog authority and publish live updates

* fix(native-chat): publish authoritative command catalogs on session updates

Brennan BensonandMerge Sim 68dd3909c7 feat(orchestration): orchestrate native-born structured chat sessions (#18827)
* feat(orchestration): orchestrate native-born structured chat sessions

Orchestration resolves every worker through a terminal handle and a pane key
backed by a live PTY. A session created directly as structured has neither, so
it was not refused by orchestration — it was invisible. A coordinator could not
start one, address one, or receive `worker_done` from one.

Add a second authority source rather than a parameter channel. A registry maps a
session id to the same three facts the PTY path supplies — a bearer handle, a
pane key and a host scope — and the four runtime getters consult it before
giving up on `ptysById`. `orchestration.send` and `verifyDispatchCapability` are
untouched: authority stays host-derived and the CLI still cannot assert who it
is. PTY handles short-circuit on the handle prefix, so the terminal path is
unchanged.

Mail travels as a session turn instead of as bytes, on a sibling lane that keeps
the PTY lane's outstanding-run, waiter, reserved-type and batch rules.
Orchestration's database stays the source of truth; the send is best-effort,
exactly as the byte write is, and mail is consumed only on a proven-accepted
dispatch. Delivery waits for the session to be between turns, because one
provider refuses a mid-turn start outright and the other cannot acknowledge one
inside the ack window.

Security properties, each pinned by test: the pane key's leaf is random and
persisted rather than derived, since `check` is identity-gated and accepts a
caller-supplied pane key; the handle is a random bearer token; the child env
carries no pane key, which would otherwise flow into hook pipelines that assume
a PTY leaf; hook attestation stays closed for structured handles; and process
continuity comes from record lineage, never the runtime fence, which the host
bumps during its own crash recovery.

Also remove the "Orchestration paused" notice, which gated only on dispatch
status and rendered over bridge chat where orchestration always worked; refuse
the implicit-sender fallback when a worktree has more than one candidate leaf
instead of guessing; and collapse the archive kinds to one named type with a
compile-time assertion that the capture set cannot drift ahead of the storable
set.

* fix(orchestration): answer the structured idle gate from the reduced timeline

The structured pointer gate read a bounded 40-item tail page. A settled turn is
tombstoned rather than rewritten, so an idle worker with any real history carries
no turnLifecycle item at all and the "full page, no lifecycle item" guard read it
as busy forever: every nudge after the worker's first substantial turn parked on a
settle edge that had already passed, and the preamble tells workers not to poll.
The attention gate had the mirror bug — a prompt older than the tail window was
missed and the nudge was delivered into a session blocked on a human.

Both facts now come from `journal.snapshot()`, the fully reduced timeline, via a
new narrow `readGateFacts` host read; the policy module stays pure and still
projects through the shared helpers the chat view reads.

Also:
- Park `session-not-attached` on the journal edge, so mail that arrives during a
  transient detach is redriven by the re-attach reset instead of sitting unread.
- Resolve a structured worker's provider from the durable agent-session record
  when the registry entry was rehydrated, so a restarted Codex worker is no longer
  reported and archived as Claude.
- Clear `structured_pointer_operations` in every `orchestration reset` scope.
- Drop the per-chat-pane dispatch-status store subscription left behind by the
  removed paused notice, and re-pin the two terminal-pane ratchets it moves.
- Hoist the identical pointer batch selection out of both delivery lanes into
  `selectOrchestrationPointerBatch`.
- Refuse the pre-graph-ready focus-based guess for `requireUnambiguous` callers,
  matching the ready path.
- Move the host teardown phase list into the teardown module it belongs to, which
  is what keeps the host inside its max-lines budget.

* fix(orchestration): discard a structured worker session whose create settled unknown

`commitStructuredAgentSessionCreate` answers `agent_session_operation_unknown` when
`attach` SUCCEEDED and only the tab publish failed, so `created.ok === false` is not
proof that nothing exists. The worker start read it that way and skipped
`discardCreatedSession`, leaving a live provider child that took no hold, has no
`bindingsByDispatchId` entry and no published tab — the outer
`releaseStructuredWorkerSession` no-ops without a binding, and a session that never had
a holder never starts the eviction clock, so nothing in the runtime ever retires it. A
throw out of the commit half is past `attach` for the same reason; the pre-commit half
refuses rather than throwing. Cleanup now asks whether the create MAY have committed,
via the existing `isDefinitiveAgentSessionCreateRefusal` predicate.

Also:
- Strengthen the pre-ready `requireUnambiguous` test so it actually pins the guard: the
  snapshot now carries a focused terminal, so deleting the `? [] :` ternary turns the
  test red instead of leaving the refusal to the ambiguous `listTerminals` fallback.
- Correct the guard's justification comment, which cited `orchestration check` as
  covered. `check` resolves through the `--terminal` scope and still guesses; the
  guard covers the implicit `--from` sender, and a structured worker is covered by the
  `ORCA_TERMINAL_HANDLE` baked into its child.

* docs(orchestration): stop two structured-worker comments claiming guarantees the code does not give

The send-time owner re-check reads `target.refusal`, the snapshot the resolver
already admitted, so `decideStructuredPointerDelivery` can only agree with the
resolve-time answer and `owner-not-settled-native` is unreachable from that call
site. What actually fences an owner that moved is `expectedRuntimeFence`, which a
handoff bumps. Say that, so nobody later drops the fence trusting a re-check that
is structurally a tautology.

`discardCreatedSession` was credited with retiring "a published background tab
that no dispatch owns". It hides the DURABLE tab reference and closes the
session; the live tab snapshot keeps the row, so the background tab this start
published stays on screen until the app restarts. Same for stop and release. The
comment now describes what the two calls do — including that both are no-ops on a
session that was never attached, which is what makes the non-definitive-refusal
path safe to reach unconditionally.

* fix(orchestration): retire a structured worker's chat tab when the worker settles

Starting a structured worker always publishes a real `agent-session:<id>` tab, but
every settlement path only called `setSessionTabVisibility(sessionId, false)` plus
`host.close(sessionId)`. That clears the DURABLE restore index and leaves the LIVE
snapshot untouched, so stop, release and the half-started discard all left a dead
"Claude Chat" / "Codex Chat" tab in the worktree's tab bar for the rest of the app
session — five dispatches, five dead tabs — and opening one re-attached the released
session, respawning a provider child outside orchestration's hold accounting.

The snapshot-pruning half of `closeStructuredAgentSessionTab` is extracted into
`structured-agent-session-tab-retirement.ts` and exposed on the runtime as
`retireStructuredAgentSessionTabFromSnapshot`, so the user-initiated tab close and
the three settlements share one implementation instead of a second copy.

The settlement side is best-effort BY CONSTRUCTION: it runs only after the close is
already proven, calls the runtime method optionally, and swallows any throw. It
talks to no renderer, so the startup release reconciler can call it too. Nothing
here can turn a proven stop into `release_unknown`.

* fix(orchestration): stop a structured worker's nudges, archive and liveness from lying

Five defects in the structured-worker lanes, each with the same shape: a check
that answered from something other than what it claimed to measure.

- The pointer lane gated a WORKER's `dispatch:` mailbox on its RUN's outstanding
  delivery. Delivery rows exist only for a `run:` address, so that row belongs to
  the coordinator — and a coordinator holds one for exactly as long as it is
  acting on received mail, which is when it replies to its workers. The gate is
  gone; there is no coordinator mailbox in this lane to protect.
- `dispatch-rejected` now parks on the journal edge. A rejection consumes no mail
  and nothing else redrives the mailbox, so an unparked pointer left the worker
  idle on durable mail until unrelated mail happened to arrive.
- The released journal archive bounded forward — keeping the HEAD — before
  capping newest-first, so a long worker's archive ended at its early exploration
  and dropped the answer it was released for, under a warning that said the
  oldest messages had gone. One newest-first pass now, and the warning is true.
- The durable pointer operation id was reused on a matching BODY fingerprint, and
  the body names only the unread count. Two unrelated same-size batches collided,
  the host replayed its ledger answer as `accepted` with no turn sent, and the
  lane marked the new mail delivered. Reuse is keyed on the batch's message ids.
- `worker-read` on a structured worker hardcoded `terminal: 'running'` and
  emitted no `liveness`, so a runtime that could not see the session reported the
  worker as alive. It now carries the observed verdict, as the PTY branch does.

Also: the live journal cursor is an index into a re-derived tail window, so the
page's oldest item joins its source identity — a slid window now answers
`source_changed` instead of silently resuming past the items it skipped. And a
stop that reached no host reports `processAction: 'none'`, after installing the
host the way release already does.

* fix(orchestration): stop a released structured archive claiming a close that never landed

`worker-read` on a released structured worker hardcoded `liveness: 'exited'`. The
archive is frozen BEFORE the close, so it proves nothing about the provider child,
and the read is served for `release_state` in `releasing` / `unknown` too — the two
states that exist precisely to record a close that did NOT land. A coordinator that
read `exited` from a `release_unknown` worker would start a replacement over the same
worktree while the original child was still attached, which is the outcome
docs/reference/ssh-execution-boundary.md rule 2 exists to prevent, and it contradicts
the release receipt's own "the structured session close was not proven" text.

The verdict now comes from the resource row the read already holds: only a settled
`released` row is `exited`, everything else is `unverifiable` — which the existing
mapping renders as `terminal: 'unknown'`, the same way the live branch does.

* fix(orchestration): stop a structured worker-start reporting a preamble it never delivered

Two ways a structured `worker-start` handed the coordinator a receipt that did not
describe the worker it got.

`sendStructuredWorkerPreamble` threw only on a refusal and on `rejected`, so a
submission that settled `unknown` fell through as success: the start pushed
`dispatch_input: accepted` and marked the dispatch ready. `unknown` is not rare —
`dispatchSafely` converts ANY thrown adapter call (provider child gone, transport
dropped, ack window missed) into it, and `performSend` still returns ok. The worker
then has no task spec while its coordinator blocks in `check --wait --types
worker_done` until timeout. This PR's own mail lane already states the rule —
"`pending` is not yet an acknowledgement; only `accepted` may consume mail" — so the
preamble now applies it too, and raises `operation_unknown` for the states that
prove neither delivery nor failure, which is the code `failWorkerStartWithReceipt`
turns into the `outcome_unknown` receipt whose nextCommands send the coordinator to
look. `rejected` stays a proven failure.

`--structured` also accepted `--model` / `--effort` and dropped them: structured
session creation takes no launch preferences, while `launch.receipt.effective`
echoes whatever was requested either way, so `--model opus` ran on the workspace
default and the receipt still said `opus`. Refused now, for the same reason
`--terminal` refuses them, and the spec note records that refusal along with the
new-child/new-top-level one it never mentioned.

Tests: the refusal guard had no coverage at all, and `structured-mailbox-pointer-host`
— where the full-timeline gate read lives — had none either; reinstating the bounded
tail there left the whole repo green. Both are covered now, and the vacuous
"never selects an exact provider session" case is re-pointed at the absent
`ORCA_PANE_KEY` that actually keeps that selector shut.

* fix(orchestration): let a structured worker actually reach the Orca CLI, and stop four settlements lying

A structured worker's provider child runs `orca orchestration ...` exactly like a PTY worker's
agent does, but it was handed the ambient PATH. On packaged Linux the CLI installs as `orca-ide`
so it never claims GNOME Orca's /usr/bin/orca (#7904), so bare `orca` execs the screen reader and
the worker can never read mail, reply or send worker_done; on packaged macOS/Windows the bundled
launcher is only reachable from the app's own resources dir. The PTY lane already solves this
inside `buildPtyHostEnv`; that block is now its own module and both lanes call it.

Also:
- a worker start that fails AFTER its session exists now discards the session, so a failed start
  stops stranding a dead chat tab that the durable restore index republishes on every launch;
- a structured worker's resource reconciles to `released` after settlement forgot its identity,
  instead of answering `unverifiable` for the life of the DB;
- `closeAttempted` is set only once a close is issued, so a tab-visibility failure can no longer
  report `closed_agent_terminal` for a running child;
- `forgetSession` prunes only what the settled worker parked, not every sibling whose target
  momentarily fails to resolve;
- release settles with an explicitly empty, warned archive when the journal is unreadable AND the
  session is proven exited — closing the chat tab is routine, and `archive_failed` there wedged
  release on evidence that could never arrive;
- the new migration test uses mkdtemp and cleans up, so it stops failing Windows CI and leaking.

* fix(orchestration): merge the duplicated release-receipts import

The release-completion module imported ./orchestration-worker-release-receipts
twice, which trips import/no-duplicates in audit:code-quality:native. The
changed-file gate does not load that config, so only whole-tree CI saw it.

* docs(runtime): note that a background structured tab re-publish is a no-op

The activate:false branch for an already-published session returns without
writing the snapshot or emitting, so it cannot re-surface a client whose
mirror lost the tab. Orchestration is safe from this only incidentally.

* feat(orchestration): make the worker mode the user's own default, not a flag

`worker-start --structured` was an explicit opt-in that REFUSED --on, --terminal,
--model/--effort and worktree-creating placements. The flag, its spec entry and the
`structured` RPC param are gone: the mode now follows the user's setting for new agent
tabs, so a local claude/codex worker is a structured chat session whenever the user's
own default says agent tabs open as one.

A setting is a preference, not a demand, so none of those combinations refuses any more.
A dispatch that cannot be structured starts an ordinary PTY terminal worker and the
receipt names the mode that ran and why, so the fallback is never silent:

- a remote --on, an existing --terminal, a new-child/new-top-level worktree and
  --model/--effort are decided from the request;
- the agent, TUI launch customization, Codex-on-Windows and the runtime capability are
  decided by the shared launch route;
- WSL, remoteness and the Windows start-time gate are settled by the executing host's own
  agentSession.createSupport, asked once the worktree resolves and before anything is
  created, so a refusal is a terminal worker rather than a failed start.

The decision is the renderer's, lifted rather than copied: `resolveAgentLaunchRoute`'s
structured half and the settings predicate now live in
shared/structured-native-chat-launch-route, which both surfaces call, and the TUI launch
customization test moves to shared beside it. `getClientSettings` gains the two native-chat
default booleans it was missing.

No security invariant moves: the structured worker registry, bearer handle, persisted pane
key, the absence of ORCA_PANE_KEY from the child env, hook attestation and lineage-derived
process incarnation are untouched.

* fix(orchestration): stop the worker mode leaking into the agent contract

The mode a worker runs in is a runtime implementation detail. An agent should be
taught the same verbs, run the same commands and read the same receipts whether it
is a structured chat session or a PTY terminal — otherwise a settings-driven
fallback silently changes what the agent can do.

The real leak was `canDispatchSubWorkers`, which was forced false for a structured
worker. That was not a wording choice: `worker-start` resolved `--from` through
`showTerminal`, which needs a live PTY or renderer leaf, so a `structworker_`
coordinator genuinely could not dispatch. Rather than withhold the capability, the
one fact the command needs from `--from` — its worktree id — now comes from
`getOrchestrationDispatchAuthority`, the same authority the pane-key and
process-incarnation getters already answer structured handles from. Sub-dispatch is
gated on depth alone, identically for both modes.

`showTerminal` itself is deliberately NOT taught structured handles: it returns a
ptyId, a leaf id and a pane runtime id, and synthesising those for a session with no
PTY would hand every caller of a public terminal verb something that looks writable
and is not. `inspectWorkerTerminal` already returns `terminal: null` for exactly
that reason.

Also neutralised three agent-visible refusals that named the worker's kind: a
`worker-read --source terminal` on a worker with no terminal now names the sources
that do work, and both archive refusals say "transcript output" rather than
"structured chat output" (the PTY `transcript_pin` branch said "structured" too).

New tests pin both properties: the two preambles are byte-identical once the handle
and per-dispatch ids are normalised, and a structured coordinator starts a worker
with `showTerminal` rejecting.

* fix(orchestration): stop claiming a structured worker was checked for a prompt

worker-show reported observation.agentWait: null for every structured worker. The
field's own contract says null means Orca looked and found no wait, and absent means
it never looked — and nothing looks here: a structured worker parks on a journal
question item, which no terminal prompt scan can see.

So null was a false negative on the one field a coordinator is explicitly told to
read, and it was mode-dependent: the same worker as a PTY would have reported the
wait. Absent is both the honest value and a state a PTY worker already reaches (an
older host, an unreadable pane, a probe that did not answer), so it discloses
nothing about which mode ran.

* docs(cli): stop the worker-start spec pointing a caller at the worker kind

The note said "the receipt mode field names the mode used and why", which is an
instruction to read a field no verb behaves differently for — the one thing the
mode was not supposed to become. It now says what a caller actually needs: the
dispatch always starts, the options passed are the ones honoured, and every worker
is driven the same way. The receipt still carries the mode for operators and
telemetry; nothing tells an agent to look at it.

* perf(orchestration): coalesce the structured redrive edge

Every journal batch is a redrive candidate, because a settled turn is tombstoned
rather than rewritten — there is no completed row to watch for. That is free while
nothing is parked on the session, but once mail IS parked each batch re-resolved the
dispatch, queried unread mail and read the host's gate facts, only to re-park because
the turn was still running. A turn streaming tool calls paid that per batch.

The edge now coalesces on a 300ms quiet window with a 2s starvation cap, so a
streaming turn costs a handful of evaluations instead of one per batch and a settled
turn still nudges promptly. Delivery semantics are untouched: the gate, the
accepted/rejected/unknown handling and the retain rules all still run exactly as
before, just fewer times. Nor is this the path fresh mail takes to an idle worker —
that is `deliverForHandle` at enqueue time, which this does not touch — so the
common case gains no latency.

The mechanism is the session.tabs notify coalescer, generalised into
`keyed-trailing-edge-coalescer` and called by both rather than duplicated; the
session.tabs windows stay where they were, since 50ms is right for a spinner title
and far too tight for a journal stream. Disposal drops the pending timer rather than
flushing it, on the existing subscription disposer that every settlement already
reaches, so a redrive can never fire for a session no dispatch owns.

* fix(orchestration): deliver direct peer mail to a structured worker, and let a peer read it

Two agent-to-agent verbs had no answer for a worker that IS a structured agent
session, and both failed quietly.

Mail addressed to a worker's own bearer handle — how agents mail each other
outside a dispatch — fell between the lanes. The send stored durably and
reported success, `getLiveTerminalPaneKey` resolved the recipient, and then
neither lane claimed the mailbox: the structured resolver answered only
`dispatch:` addresses, and the PTY lane refuses a structured handle outright.
Nothing errored and nothing logged, so the worker never reacted and the peer
waiting on a reply hung. The resolver now also answers a bare worker handle,
preferring that worker's active dispatch so peer and coordinator nudges share
one operation-ledger budget. A worker BETWEEN dispatches is still nudged, under
a session-scoped key: a dispatch says nothing about whether delivery is safe —
the idle gate and the lease fence do — and its own `check` reads exactly the
direct mailbox the mail is sitting in. The dispatch caller key is left
byte-identical, because the ledger is keyed on (callerKey, operationId) and
reshaping it would re-mint nudges already in flight as second turns.

`terminal read` had no structured branch, so the only peer-accessible read verb
answered `terminal_handle_stale` for a live worker; `worker-read` is closed to a
peer, which holds neither coordinator standing nor a dispatch id. It now serves
the session's journal, projected to LINES and paged by the same reader the PTY
tail uses, so the result stays a plain RuntimeTerminalRead and nothing an agent
reads discloses which kind of worker answered. Bounding and dispatch-capability
redaction are the archive path's, reused rather than rebuilt. A session that is
not attached refuses with the existing not-attached code rather than returning
an empty tail, which would read as "this worker has said nothing".

`terminal.show` still refuses a structured handle. This is read-only on purpose:
synthesising a ptyId/leafId/paneRuntimeId would hand every public terminal verb
something that looks writable and is not.

* fix(orchestration): stop three PTY-only probes answering for structured sessions

Three defects, one shape: a probe that enumerates PTYs or resolves a pane was
standing in for a question that is not about panes at all.

`worktree rm` destroyed a live structured worker. `killAllProcessesForWorktree`
sweeps the renderer graph, the provider session list and the local pty-registry,
and a structured session is registered on none of them — so all three counted
zero, nothing errored, and removal deleted the checkout out from under a running
provider child, which kept running with its `cwd` gone while the dispatch still
reported the worker live and exact. A fourth sweep now asks what the other three
cannot: membership by `location.workspaceId`, which covers a plain chat session
as well as a dispatched worker, and liveness by the same
`live`/`unverifiable`/`exited` observation the rest of the structured surface
uses. It REFUSES a destructive removal rather than auto-closing, on the same
bargain and the same `--force` escape hatch as the unstopped-PTY gate — this is
the verb that deletes a user's work, and a running agent is exactly what they
would want to be told about. Force closes the sessions properly instead of
orphaning a child. Best-effort reconciliation callers are excluded: they repair
state, delete nothing, and must never be failed closed.

Twelve coordinator verbs failed for a structured worker running as itself.
`isLiveTerminalHandle` validated `ORCA_TERMINAL_HANDLE` with `terminal.show`, a
PTY verb whose leaf lookup misses for a session that never had a pane; the pane
remint that would have recovered it needs `ORCA_PANE_KEY`, which a structured
child deliberately does not carry, so every one of them died on
`no_active_sender_terminal` — including the ones the worker's own dispatch
preamble tells it to run. The identity question gets its own probe,
`terminal.resolveIdentity`: a handle and a boolean and nothing writable.
`terminal.show` still refuses a structured handle, because synthesising
ptyId/leafId/paneRuntimeId would hand every public terminal verb something that
looks writable and is not. The PTY half is byte-for-byte today's check,
`getLiveLeafForHandle` included, so its `rendererGraphEpoch` re-check still runs
— that check is the whole reason the sender is validated at all, and a cheaper
probe would have quietly started passing stale post-reload handles. A host that
predates the method answers `method_not_found` and the client falls back to
`terminal.show`, which is correct for that host: one without the identity probe
has no structured workers to miss.

`dispatch --inject` reported `no_agent_detected` for a structured worker, because
`isTerminalRunningAgent` reaches `getLiveLeaf`, throws, and the catch returns
false. A structured session IS the agent; there is no foreground process to
recognise, so it answers before the PTY probes rather than through them.

Also: a Run whose coordinator is structured now gets its `run:` mail. Both lanes
declined and neither logged — the PTY lane because the owner is structured, the
structured lane because the mailbox was not `dispatch:` — so each half believed
the other owned it. The PTY lane's reasoning (a coordinator blocks in
`check --wait`, where a waiter preempts pointer delivery) does not transfer: a
structured coordinator is a chat session whose turn ends. Its `run:` deliveries
take the `hasOutstandingRunDelivery` gate the PTY lane applies for exactly that
mailbox, and only for that mailbox.

The test that would have caught the twelve drives the CLI with
`ORCA_TERMINAL_HANDLE=structworker_…` and no `--from`. Every existing
orchestration CLI test passes `--from` explicitly, so the resolver a real worker
goes through was never exercised — which is why the suite stayed green while the
preamble failed on its first line.

Two files crossed their line ceiling and are split rather than waived:
`worktree-teardown.ts` sheds its two PTY-surface sweeps and the deadline
arithmetic they share, and `orchestration.test.ts` — which sat exactly on 800 —
sheds the two caller-identity suites this change rewrote.

* fix(orchestration): arm the takeover signal for structured chat input

`worker-release` closed a structured session a user had taken over, losing work
mid-conversation, while `orchestration-worker-specs.ts:106` promised "Never
closes … user-taken-over terminals".

Every guard was already correct and simply never armed.
`reportWorkerTerminalUserInput` has exactly one call site — the real-user-input
signal on a PTY connection — so structured chat input never reached
`orchestration.workerTerminalUserInput`, `markWorkerTerminalUserOwned` never ran,
ownership stayed `owned` instead of `user_owned`, `retainedReason` never returned
`user_takeover`, and `stopStructuredWorker` proceeded. The durable flag is reused
as-is rather than given a parallel mechanism: it exists precisely so a restart,
an SSH drop or a renderer remount cannot erase a takeover.

Addressed by SESSION, never by pane key. A structured worker's pane key is a
random identity credential — anyone holding it can read and consume that worker's
mailbox, and session ids are embedded in tab ids in plain text — so it stays in
main and the runtime resolves the session to it. Handing it to a renderer to echo
back would make it learnable by anyone who can see a chat pane. The RPC gains an
optional `sessionId` alongside `paneKey`; a host that predates it rejects the
call, and the report is already best-effort with a catch, so that host degrades
to exactly today's behaviour rather than failing a send.

The signal fires from the composer send hook and only past `accepted`: the outbox
dispatcher retries, and orchestration's own pointer nudges never pass through the
composer at all — so neither can be mistaken for a user takeover.

* fix(orchestration): reach structured workers through group addresses

`orca orchestration send --to @all` — and `@idle`, `@claude`, `@codex`,
`@worktree:<id>` — silently skipped every structured worker. Recipients came
from `listTerminals`, which enumerates leaves and PTYs, and a structured session
is on neither. The exclusion happened BEFORE per-recipient resolution, so the
`SendRecipientWarning` machinery never ran: the caller got exit 0 and a receipt
naming the workers that did resolve, and a broadcast "stop work" or "base moved"
reached the PTY workers and nobody else. With every worker structured it
degraded to `terminal_not_found`, which reads as "the group was empty".

Fixed at the group-resolution site rather than inside `listTerminals`. That
result is published to paired mobile and remote clients and to consumers that
assume a summary carries a `ptyId` or is writable, so widening it is its own
change under `docs/reference/remote-wire-compatibility.md`. Group addressing
reads exactly three fields off a recipient, and `RuntimeTerminalSummary` already
satisfies them structurally, so the resolver widens to that smaller shape and
nothing here invents a `worktreePath` or a `branch`. Candidates are liveness-
gated on the same observation the rest of the structured surface uses — mail
addressed to a settled worker would be stored for a lane that will never deliver
it — and once a worker IS a candidate, the existing per-recipient warnings cover
it, so an unresolvable one is reported rather than dropped.

`@idle` needed more than enumeration: `getAgentStatusForHandle` reaches a PTY
probe that throws for a handle with no pane, so a structured worker would have
been enumerated and then silently dropped from the one group address that
selects on status. It now answers from the session's journal — and off the FULL
reduced timeline, never a bounded tail. Settlement tombstones the running turn's
lifecycle item rather than rewriting it, so on any page-sized read a long
tool-calling turn looks identical to an idle session; `@idle` would then
broadcast into a running turn, which Codex answers with `turn already running`
and Claude queues behind. An unreadable session answers null, never idle.

`terminal list` and `worktree ps` still omit structured workers; that is the
wire-visible half and is deliberately not in this change.

* fix(orchestration): refuse rather than guess when a chat session has no identity

An ordinary structured chat session — not a dispatched worker — is spawned with
no `ORCA_TERMINAL_HANDLE`, because `structuredWorkerChildIdentityEnv` early-
returns for any session outside the worker registry. `orca orchestration check`
then fell through to `terminal.resolveActive`, which picks the focused tab's
active leaf or the first leaf in the worktree. It returned a valid handle, so
nothing errored — and `check` is destructive by default, so it consumed another
pane's oldest unacknowledged batch and marked it read. The rightful worker never
saw that mail.

`requireUnambiguous` does not fix this, only narrows it: it refuses when MULTIPLE
leaves could be meant, and with exactly one terminal pane in the worktree the
guess still resolves — to a sibling. "One terminal pane plus one chat tab" is a
normal layout, so the common case stayed broken. The pinned test is that case.

So the child now carries `ORCA_STRUCTURED_SESSION`, and every remaining route
that would GUESS an implicit terminal refuses on it with an error naming the flag
to pass. The marker names NOTHING — no handle, no pane key, no session id, no
token — which is the whole reason it is safe: it cannot be replayed, cannot
impersonate, and cannot flow into the hook-attestation, agent-row or
mobile-projection pipelines the way a pane key would. That makes it a different
decision from withholding `ORCA_PANE_KEY`, not a reversal of it. It also grants
no CLI reachability, so packaged builds keep exactly today's exposure.

The comment at `orca-runtime-adopt-terminal-orphans-from-inventory.ts` that
justified the guess — "a structured worker is covered instead by the
`ORCA_TERMINAL_HANDLE` its child is spawned with" — was true only for dispatched
workers and false for every other structured session, a population this branch
creates. It now says which case it covers and which case it does not.

* fix(orchestration): stop two surfaces lying about a worker with no terminal

`orca terminal <verb>` answered `terminal_handle_stale` for a structured
worker's handle. Nothing went stale: the session is live and simply has no
terminal, and it never had one — so callers acted on a false claim and went
hunting for a remint that cannot exist. The refusal now carries its own code and
names the structured equivalents (`orca terminal read`, `worker-read --source
transcript`, `orca orchestration send`), so an agent that lands there learns
what to run rather than what failed. A PTY handle that really did go stale keeps
the old error, and so does a session this runtime no longer owns — that handle
IS dead. `terminal.show` stays non-resolving: synthesising a
ptyId/leafId/paneRuntimeId would hand every public terminal verb something that
looks writable and is not.

`orchestration-worker-specs.ts` promised "the same verbs, the same handle, and
the same worker-read sources", and all three clauses were false for a worker with
no terminal. A spec agents read must not carry a false promise, so it now states
the limitation and the alternative that always works.

Note this had to be reconciled with an invariant this branch already holds: the
worker MODE must stay opaque, or a coordinator starts branching on something no
verb it runs behaves differently for. So the note says "not every worker has a
terminal" and points at `--source auto`/`--source transcript` WITHOUT naming a
kind — the same mode-neutral wording `readStructuredWorkerOutput` already uses
when it refuses `--source terminal`. Both properties are now pinned by tests, so
neither can be restored by breaking the other.

* fix(orchestration): close the review findings on the structured parity work

Four defects and two follow-ups from the delta review.

The `worktree rm` refusal was a dead end in the desktop UI. Its message matched
no matcher in `classifyWorktreeForceDeleteReason`, and an ordinary desktop delete
already passes `force=true` for the dirty-file skip, so classification returned
null unconditionally: the toast showed raw CLI wording with no Force Delete
button, and a user with a live chat session was stuck unless they knew to reach
for the CLI. That is the #11960 shape `shared/worktree/removal.ts` documents, so
the refusal now has its own prefix, matcher, `WorktreeForceDeleteReason` and
toast copy, classified BEFORE the `force` guard and nulled once the waiver is
spent — exactly how `unstopped-pty` is handled, with matcher and hint kept in
the same file as that contract requires. The copy says Force Delete will close a
running conversation rather than borrowing the "could not confirm" wording,
because Orca watched these sessions stay attached; there is no doubt to waive.

Structured `terminal read` cursors were unsound and are now refused. The PTY
cursor indexes an append-only completed-line buffer with a monotone count; a
session journal is a BOUNDED tail re-projected on every read, so a saved index
addressed different lines as the journal grew — and `truncated` could never fire
to say so, because it tests `cursor < oldestCursor` and `oldestCursor` was always
0. A poller got wrong or duplicated lines under `truncated:false`. Separately, a
streaming turn's lines counted as completed with `partialLine` hardcoded empty,
so a mid-turn cursor consumed a half-written line whose growth was never
redelivered — the `"hel"`/`"hello"` hazard the PTY reader guards against. The
journal does have stable item identity, but `terminal.read`'s cursor is a number
on the wire and cannot carry it, so a cursor read now refuses and names
`worker-read --source transcript`, which already has that contract including
`source_changed`. No cursor space is advertised either: `nextCursor` is null and
the cursor fields are absent, rather than claiming an index the next read cannot
honour. The header claim that all four fields kept their meanings was true of the
shape and false of the invariants; it now says which ones hold.

Two fixes had no test at their real seam, which is the same failure that produced
this whole set — the runtime tested directly, the seam tested by neither. The
group-addressing test hand-composed the recipient list itself, so deleting the
composition at the call site left it green; it now drives `sendGroupMessage` with
no PTY terminals at all. Nothing referenced `isLiveStructuredAgent`, so the
`dispatch --inject` fix had no red-then-green at all; it now has one driving
`RuntimeTerminalAgentPresence.isRunning`. Both were ablated and confirmed red.

Folder-workspace removals sweep and kill PTYs without `requirePhysicalStop`, so
the structured sweep no-opped there and left a live session bound to a workspace
about to be forgotten. They now close best-effort under an explicit
`closeStructuredSessions` flag, kept separate from `requirePhysicalStop` because
the two questions differ: that one asks whether a stop must be PROVEN before
files are touched, and it is what licenses a refusal. These paths do not refuse —
the root is shared so no checkout vanishes under the child, and one of them is a
never-throw forget a refusal would wedge. Reconciliation sweeps set neither and
still close nothing.

Also: the force close is raced against the same sweep deadline every PTY surface
is bounded by, so a wedged provider close reports the timeout instead of hanging
`worktree rm --force` forever; and the refusal now prints a count and the
providers instead of raw session ids, which our own marker rationale treats as
one tab-id hop from a credential.

* test: pin structured-session close on the folder-workspace removal path

The folder and orphan removal callers now pass closeStructuredSessions so a
live structured session is closed best-effort rather than left bound to a
workspace Orca has forgotten. These three exact-args characterizations describe
that call and had not been updated.

* fix(orchestration): stop the structured worker-read cursor misdelivering silently

`worker-read --source transcript` for a structured worker fingerprinted only the
oldest item's id, so `source_changed` fired when the window slid off the front
and could NOT fire when the page's contents changed under a stable oldest item —
which is the normal case, because the journal is a reduced, mutable timeline. A
`running` tool item gains its `[tool result]` at its original sequence once later
items exist, the 60ms delta coalescer revises a message in place, settlement can
rewrite an item smaller, and a pending approval projects to null until it
resolves and then appears in the MIDDLE of the array.

Two silent failures followed, both returning ok. Omission: a caller handed a
coalesced `hel`, resuming past it, never received the revision to `hello world`
— the same defect we refused to ship on the terminal read path, already shipped
here. Duplication: a resolved approval inserted ahead of a saved index, which was
still accepted, so the caller re-read content it already had. The blast radius is
the coordinator polling loop, the verb's primary consumer.

The anchor is now the oldest item PLUS every item whose projected message sits
below the caller's position, by id and revision. `createWorkerOutputSourceIdentity`
already takes an arbitrary string array and the cursor is already opaque
base64url carrying its own position, so neither the wire shape nor the
`source_changed` contract changes.

Prefix-scoped rather than whole-page deliberately: fingerprinting every item on
the page would flip the identity every 60ms with the coalescer window during an
active turn, making the cursor unusable exactly while the worker is working —
that trades a silent bug for a useless verb. Tail growth the caller has not read
cannot invalidate; any change to what it already holds does. Position-dependence
is safe because `p` rides in the same opaque payload as the identity, and the
returned cursor is stamped with the identity of its own end, which is precisely
what the next read recomputes. The frozen archive keeps a constant identity: no
item can be revised under a caller there, so it has no prefix to fingerprint.

Both silent shapes are pinned across a page boundary with the journal mutating
between reads — a static-journal test passes either way. Two ablations at the
real call site: reverting to the oldest-item-only anchor turns both red, and
widening the prefix to the whole page turns the tail-growth case red, which is
what proves the scoping is real in both directions.

* docs(orchestration): stop the structured terminal-read refusal recommending a dead end

The refusal told a peer to "page it with `orca orchestration worker-read
--source transcript`", which is wrong three ways and this file said so itself:
its own header explains that this verb exists BECAUSE `worker-read` demands a
dispatch id and coordinator standing "a peer does not have" — and then the
refusal sent that same peer there. The verb it named is also a window index over
the same bounded page, so it is not a paging answer even for a caller who can
reach it; under load it now answers `source_changed` on most polls, which is
better than the silent hole it had before but still not what the sentence
promised.

The refusal now says what actually works — the tail is bounded and newest-last,
so poll it and diff — and names no alternative, because there is none. That is
the honest framing: a durable cursor is not achievable here at all, rather than
blocked on the wire shape. The journal is a reduced, MUTABLE timeline: an item's
projected text changes at its original sequence after later items exist, the
delta coalescer revises repeatedly, settlement can rewrite an item smaller, a
pending approval renders as nothing and then as something, and `sequence` resets
on epoch rollover. No index, numeric or opaque, survives that.

So the docstring's "pagination with a real anchor lives on `worker-read --source
transcript`" is gone too — there is no real anchor there — and the file now
records why no windowed alternative should be built later: a broken cursor fails
UNSAFE, as a silent hole in a poller's output, while diffing a bounded tail fails
safe as a harmless re-read, and a second paging-shaped verb would invite the PTY
assumptions this one cannot honour.

The test asserted the old advice, so it now pins the contract instead: the
refusal explains the working approach and must never name `worker-read`.
`worker-read --source transcript` remains a good bounded snapshot for a
coordinator reading a worker it dispatched; only the "or page it with" clause was
false.

* fix(i18n): add the missing worktree-removal agent-session refusal string

The structured-session removal refusal introduced a translate() key with no
en.json entry. Nothing local catches that: typecheck passes, and the full
suite passes, because a missing key falls back to its inline default at
runtime. Only verify:localization-catalog fails on it, which is why CI's
static analysis reddened on a branch that was green everywhere else.

Fallback wording mirrors the sibling unstoppedPtyLive string, since the two
refusals differ only in what is still running and what Force Delete does to it.

* test(codex): expect the no-identity marker on an unregistered structured child

The refuse-rather-than-guess marker landed after these expectations were
written, and all three assert exact env equality on the unregistered path —
the one branch that now carries ORCA_STRUCTURED_SESSION. One of the two files
was added by this same branch, so this is a self-inflicted drift; the other
predates the branch and was broken by it.

The marker's presence is still pinned positively by
structured-worker-child-identity-env.test.ts and the CLI's
orchestration-structured-session-no-identity.test.ts, so relaxing these three
exact-equality checks loses no coverage of the security property.

* fix(orchestration): require exit evidence before settling structured close
