Brennan BensonandClaude 6627c6503c refactor(agent-session): keep which conversation each chat tab shows in one host table (#22709)
* refactor(agent-session): keep which conversation each chat tab shows in one host table

The host now persists one table in the agent-session store, from chat tab id to
the conversation that tab currently shows. It replaces both the visible-session
list and the per-record surfaceTabId, so there is one answer to "which chats have
a tab, and under what id".

- /clear moves the tab's entry from the old conversation to its replacement in
  the same transaction that commits the clear. No record carries a copied tab
  id, so a tab id names one conversation by construction, and the lookup from a
  conversation to its tab returns at most one id.
- A create that reserved a tab id claims it in its reservation transaction;
  uniqueness is a key check on the table. A create that fails releases its
  claim, and hiding a chat frees its id.
- Showing a chat with no entry gives it today's id, structured-agent-session-<sid>,
  unless a cleared chat's tab kept that id; then it gets a fresh one.
- A close that does not land puts the tab back under the id it had.
- Stores written by older builds are seeded on read from the visible list and,
  for chats that have one, the record's surfaceTabId. That field is no longer
  part of the record type, is never written, and is read only by this seed when
  the file has no table. The visible list is still written, derived from the
  table, for older builds.

Tab snapshots, status keys and worker pane keys are unchanged.

* fix(agent-session): take a reserved chat tab id when its tab is published

A create that reserved a tab id put it in the tab table at reservation, and table membership is
visibility. A create that stopped before its tab was published (a crash, or a failure after the
provider started) left an entry that the next launch either restored as a tab nobody asked to see
again or kept forever with no way to close it. Reservation now only refuses an id another chat's
tab holds; the id is taken when the tab is published, so there is nothing to release on failure.

The create reply now reads the tab id after publishing, so an unreserved create answers with the
id its tab was given, as it did before the table, and agrees with a replay of the same create.

* fix(agent-session): seed a chat cleared before the upgrade under its first tab id

A chat cleared on an older build shows a later conversation of its /clear chain in the tab that was
opened for the first one, and clients key that tab, its read state and its status by the first
conversation's id. Seeding gave it the latest conversation's derived id instead, so the stored id
disagreed with the one clients hold and with what a /clear on this build leaves behind.

Seeding now follows the source records' committed clears back to the chain's first conversation
and gives the chat showing the chain that conversation's id. Those chats seed first, so a cleared
conversation reopened from history takes a fresh id when its own is held. A seeded chat is no
longer dropped when every candidate id is taken, and the table keeps the visible list's order.

* fix(agent-session): give a reopened cleared chat the same tab id at runtime and at seeding

A cleared conversation reopened from history got a random tab id at runtime but a
deterministic `-reopened` id when the table is seeded from an older store. One rule now
serves both, so a table dropped by an older build and seeded again gives that chat the
id it already had.

Brennan BensonandClaude d443320af2 refactor(native-chat): remove the unused terminal handoff (#22783)
* refactor(native-chat): remove the unused terminal handoff

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

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

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

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

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

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

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

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

* test(native-chat): pin that a start dead before proving owes no settlement

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Brennan Benson e0144a9eb6 fix(native-chat): show the Codex and Claude model picker the moment a chat opens (#22756)
* fix(native-chat): show the Codex and Claude model picker the moment a chat opens

A new structured chat showed no model picker until its session had been
created, spawned, initialized and had answered a model listing — and the
picker then listed the models a second time. Codex's listing often goes to
the network, so the picker took 0.6-2 s to appear.

- Keep a host-owned model catalog per agent and account home, persisted on
  success only and refreshed in the background once it ages out. A new
  read-only agentSession.modelCatalog RPC answers from it without a live
  session; sessions reuse it instead of listing again.
- Render the picker while the launch is still provisional, showing the saved
  default. A pick made before the session exists is held and applied once it
  publishes; only the host's acceptance saves it as the default.
- Mark the model and effort set in the user's Codex config as the listing's
  default (config/read), so the first frame names what the chat will run.
- Resolve the account a record-less read would use without running launch
  preparation, which writes and syncs account state.

* fix(codex): disable plugins in the model catalog probe app-server

* fix(native-chat): read the host model catalog only for panes on this machine

* fix(native-chat): name a pre-report model only for a chat this view launched

* test(native-chat): pin the launch latch across publish

* test(native-chat): pin a held pick reaching the host before the first send

* test(native-chat): type-check the first-send order fixture

* refactor(native-chat): keep the structured options hook under the line cap

* fix(native-chat): send the first turn only after every pick held during launch settles

* fix(claude): name no default effort from the catalog probe listing

* fix(native-chat): name no listed default model for a chat resumed from history

* refactor(native-chat): let the launch own picks made before it publishes

A pick made while a chat launches had no fence to go to, so the pane held it
and flushed it after publish; every other sender (the outbox, the launch
prompt) then needed its own gate to wait for that flush. The launch now keeps
those picks in its own state, applies them against the create receipt's fence
before it counts as published, and every sender follows publish by
construction. The pane flush, the outbox gate and the module-wide held-pick
registry are gone.

The launch also snapshots the saved selection its create seeds when the intent
is built, so a pick in another chat no longer relabels one still launching, and
a pick the host refuses is reported the way a refused mid-session pick is.

* fix(native-chat): name no default model a workspace's own config can replace

The catalog's default is the account's, read without a working directory, but
a chat runs in its worktree, where a project config (Codex's .codex/config.toml
between the project root and the worktree, or a Claude .claude settings file
that sets a model) picks the model instead. The picker named the account
default there while the chat ran the project's model.

A new chat's catalog read now names its worktree. The host checks that
workspace for such config (existence only for Codex, the model key for
Claude) and, when any is present or the workspace is not a local directory,
serves the listing with no default, so the picker names nothing until the chat
reports its model.

* fix(native-chat): name the listed default model before the report only for Codex

* fix(claude): let an option pick made while Claude starts wait for it instead of being refused

* fix(codex): name no listed default when the configured model is not in the listing

Brennan Benson 5e6fcca0b3 fix(native-chat): date a session by its own lifecycle, not its subagents' work (#22520)
* fix(native-chat): date a session by its own agent's rows, not its subagents'

The journal reducer's lastActivityAt is the structured status summary's
updatedAt, which the status row uses as its completion stamp and
acknowledgement clock. It took the max over every journal row, and a
session's subagents write into the same journal after its own agent has
settled, so an idle parent was re-dated and marked unread on child work.

A row now dates the session only when the session's own agent produced it:
not a row whose producer linkage names a subagent, and not a subagent
roster row (a subagent-group block), which the session writes but revises
on every child transition. The roster rule is derived from the row body;
no new persisted field. Replay folds through the same rule, so existing
journals are re-dated to their own last row on reopen.

Claude: a backgrounded subagent emits no child frames, so its re-dating
came entirely from roster revisions (task_updated, task_notification) and
from the stale-roster revision written when a journal reopens. Codex: the
roster is revised on every child token-usage report; child-thread rows
carry no producer linkage yet, and read as the session's own until they do.

* fix(native-chat): a reopened journal's verdict on stale work does not date the session

Reopening a journal settles rows the previous host left live (a working
subagent roster, a live background task) to unverifiable. Those revisions
were appended at the reopen moment, and a background-task row is the
session's own non-roster row, so a crash-restarted session with a live
shell was re-dated to the restart although no agent acted.

The reconciler now writes each verdict revision with the row's own observed
time. That is one rule at the one writer, covering both settle shapes; the
render item's observedAt was already pinned to the row's first write, so
nothing the transcript shows changes. The live-transition roster exclusion
stays: live roster revisions are written by the providers, not here.

The `recovered` row flag is not used as the discriminator: the live
unexpected-exit settlement also writes recovered rows, and a clock rule
keyed on it would stop dating a provider crash the host just observed.

* fix(native-chat): date a session by the reducer's attribution of what a row wrote

The clock read producer linkage off the raw row. A lifecycle batch names no
row-level producer, a tombstone names none, and a revision may name none while
the reducer still attributes the item to a subagent, so each of those dated an
idle parent. The clock now asks the reducer: after a row applies, whether any
item it wrote is the session's own work; before a removal, whether the item it
removes was.

* fix(native-chat): date a session's status by its own lifecycle edges

A subagent writes into its parent's journal and keeps going after the parent
settles. Every one of its rows advanced the summary's updatedAt, and the status
row re-dated a done parent to it, so an idle parent read as newly finished and
unread on each child step.

The host now publishes statusStartedAt beside updatedAt: when the session's own
agent entered its status, read off edges only it writes. Idle is when its newest
turn ended; working is when the running turn was requested, or the earliest
send still unanswered; attention is its own oldest pending ask, or a subagent's
when that alone holds it. A turn that recovery settled after its host went away
ended when that settle was written, so it reads as a completion the user has not
seen; it carries no outcome, so no completion event or notification calls it a
success. Render items carry recoveredAt, the recovered row's own write time, so
nothing new is persisted.

The sidebar bridge and the host ingest date the row and the main agent's clock
from it whenever the row shows the main agent's own state, and keep their
existing rules for a row child work holds open or a summary from an older host.
The status feed republishes when the clock moves instead of on every idle row.

* revert(native-chat): keep the journal clock over every row

The row filter this branch put on the reducer's lastActivityAt decided which
rows could date a session: a list of exclusions that each new row kind could
slip past. The session's state is now dated by its own lifecycle edges, so the
filter, its attribution helper and the backdated reopen verdicts go back to
main. lastActivityAt, and the summary's updatedAt it feeds, is again the
evidence clock over every row, including a subagent's.

* fix(native-chat): keep republishing an idle session its live child work holds open

A row held open by live child work is dated by when each reader saw the
publish, and mobile decays a working row whose evidence is older than the
staleness window. Suppressing row-activity republishes for every dated idle
session froze that evidence, so a subagent running more than 30 minutes past
its parent's turn made the row read idle on mobile. Only a session nothing
holds open stays quiet on row activity now; its state clock is unchanged.

* fix(activity): order an agent's timeline by when each state was seen

An answered ask returns a settled parent to its own turn's end, so its done
repeats the time of the done before the ask. Activity keyed and ordered
events by that time: the new done collided with the old one and was
dropped, and the row took its state from the newest-dated event, the
blocked ask, so a done parent read Blocked and needed attention.

Each state switch now records the `updatedAt` it was seen at. Events are
keyed and ordered by that, while unread and "Clear completed" still compare
the state's own time, so the answer neither re-lights unread nor revives a
cleared done. The row's state comes from the pane's own status entry, so a
clear that hid the done cannot leave it reading Blocked either.

* test(activity): pin the timeline across repeated asks, a clear, and a stale turn

Three parts of ordering the timeline by when each state was seen had no test
that failed without them:

- A second ask moves the answered done into history. Both dones share the
  turn's end, so only the history entry's own seen time keeps them apart;
  without it one done collided with the other and the timeline showed two
  Blocked events in a row. Three asks also exceed the per-pane cap, which must
  keep the most recently seen events, not the most recently started.
- "Clear completed" on an answered row must cut off past the ask, which is
  dated after the done, or the cleared row stays listed. A done that the user
  cleared must also stay hidden once a later ask moves it into history.
- A stale working row must not read as running just because the pane's own
  status says working.

Brennan BensonandClaude 6ae6ed08bb fix(claude): open structured chat without a startup deadline, and make Retry start fresh (#22364)
* fix(claude): open structured chat without a startup deadline, and make Retry start fresh

Publish the Claude session as soon as its process is spawned instead of racing
initialize against a fixed 10s deadline. Prompts sent before startup lands are
held and written in order once it does. An exit or sign-in failure before startup
ends the session with the reason and the CLI's stderr.

A create that failed because the process provably exited now carries
ownerVerdict 'exited', so the client marks the launch failed and Retry mints a
new operation instead of replaying the stored failure.

* fix(native-chat): sending into a chat that failed to start restarts it

* fix(native-chat): a send with no live owner restarts it once

A provider child that timed out or exited hands its lease back, and every
later send was refused agent_session_ownership_unknown. Clients read that
code as "not admitted yet" and resend forever, while only a surface hold
could make a new child, once per mount, with its failure swallowed.

The send now routes to a live owner, otherwise restarts one from the
persisted resume state where resume eligibility allows it (single-flight
per session), otherwise refuses with the new settled
agent_session_owner_unrecoverable. Unverifiable, reserved and handed-off
leases are left alone. The desktop hold now logs its failure.

* test(native-chat): pin the unrecoverable refusal as settled in the outbox

* test(native-chat): pin the release clock after a send restarts an unheld owner

* test: read the sent operation id without a cast

* fix(native-chat): type the send-recovery record lookup as the store returns it

* fix(native-chat): a send ensures its owner before admission, and an unheld owner idles for 30 minutes

* fix(native-chat): a create that throws releases its event sink

A child that dies between spawn and journal attach can still write through
the host's event sink, which attach unbound in onAcquiring and never re-bound
because onAttached never ran. The orchestration released that sink only when
performAttach returned a refusal; a thrown failure (the root-exit path) kept
the sink cached with its queued write, so the next attach's drain barrier and
runtime shutdown's flush waited forever.

Also pins the publish-on-root-exit clause for a start that never proved:
deleting it reddened nothing before.

* fix(native-chat): a resend the journal answers restarts nothing, and a send joining a restart rebases from the fence it replaced

* fix(native-chat): the host learns a Claude start positively, and persists only proven options

A publish-first create used to read the session's options before Claude had
answered initialize. With startup pending that read fell back to the built-in
catalog's default, so `record.options.model` was persisted as `sonnet` for
every user whose CLI default is something else; an owner handoff or a reopen
then replayed `set_model('sonnet')` and silently switched their model.

The adapter now reports `started` once startup facts are applied and saved
options restored. The host keeps a `providerChildPhase` on the session it
owns: a starting child hands over nothing but the saved options as intent,
and the `started` event re-reads the options as fact and persists them through
the same record write a user's option change takes. The status summary carries
`hostExecutionPhase` (optional, wire-safe), and the chat pane says the agent is
still starting instead of showing nothing.

A child whose exit already reached the adapter before acquire returns is no
longer handed over as live; the create fails with the CLI's diagnostic.

* fix(native-chat): a hold and a send that find the owner gone share one restart, and a send the ledger already holds restarts nothing

* fix(native-chat): a failed create answers one refusal shape, stamped once at the boundary

A create whose Claude process was seen to exit answered twice in two shapes:
the first call threw a generic runtime error, and only the replay of the same
operation carried the `ownerVerdict: 'exited'` refusal that lets a client
retry under a new operation. Three sites stamped the verdict and the store
failure path stamped nothing.

The first-hand root exit is now returned as the refusal on the first call,
with the provider's own diagnostic as its message. The verdict is stamped in
one place, at the boundary of the attach, from the durable row the operation
settled to, so every refusal shape answers the same fact and no site can
forget it. The per-site stamps are gone.

* fix(native-chat): a send into a session whose child ended restarts it before admission

A session that published and then lost its Claude child before startup (not
signed in, for one) keeps a released lease and a chat the user can still type
into. The send was refused as ownership-unknown, the outbox parked it as
pending admission, and nothing ever restarted the child: the message sat
there until the user closed and reopened the tab.

A send reaching a session with no provider child now runs the same resume a
surface's first hold runs, before the write is admitted. The resume reserves
a new fence, so that send is answered stale with the published fence and the
client's outbox re-drives under it, as after any fence change. A resume that
fails is not this send's answer; admission reports the lease as it stands.

* chore: restore pnpm-lock.yaml to origin/main (local pnpm rewrote it)

* test(native-chat): pin the pre-handover exit as a failed acquire; stub the status feed in the delivery test

An exit the adapter observes before acquire returns now fails the acquire
with the CLI's diagnostic instead of handing over a dead child; the
published-then-ended path stays pinned by the slow-init startup case. The
delivery test renders the pane, which now activates the host status feed.

* test(native-chat): a same-ID re-hold over the wire joins the one resume, and a replay reopen goes on the idle clock

* test(native-chat): a re-hold that joins a failing resume proves one resume ran

* fix(native-chat): a create whose child was proven gone answers the refusal on the first call

The previous change answered a first-hand root exit as the exited refusal on the
first call, but the common failed start never took that path: when the close
ladder proves the whole tree dead the acquisition error is a plain one, the
store-failure classifier rethrows it, and the client still saw a runtime error
first and the refusal only on replay.

The cleanup that proves the child gone now names such a failure
`AgentSessionAcquisitionExitProvenError`, carrying the provider's diagnostic,
unless it already names its own verdict (a refusal, a typed exit proof, a host
store code). The attach answers both proven-exit kinds as the refusal its replay
gives. How a failed acquisition settles and how it is first answered now live
beside the verdict stamp, in the failed-create module.

* test(native-chat): pin the outbox re-driving a stale-refused send under the resumed fence

A send into a session whose child ended is answered stale once the host has
restarted the child. The outbox keeps that operation queued and blocked, and the
fence change the resume publishes re-drives the same operation under the new
fence; the host admits it.

* fix(native-chat): a child restarted for a send nobody holds is still released

The restart a send runs for a childless session takes no holder, on the premise
that the sending surface already holds one. A one-shot writer holds nothing, so
the child it restarted had no release clock and lived until the app quit. The
write resume now arms the clock when no holder is present, as the first-hold
resume already does. The send-after-failed-start cases also pin that the stale
answer's operation is admitted when re-sent under the new fence, and that two
racing sends restart the child once.

* test(native-chat): pin the picked Claude model across a resume whose child starts on its own default

The started event re-reads and persists what the child reports. A resumed child
answers initialize with its CLI default before the saved pick is restored over
it; the record must hold the pick while starting and after started.

* Revert "fix(native-chat): a child restarted for a send nobody holds is still released"

This reverts commit e52c4a6f08.

* Revert "test(native-chat): pin the outbox re-driving a stale-refused send under the resumed fence"

This reverts commit 136a39deb0.

* Revert "fix(native-chat): a send into a session whose child ended restarts it before admission"

This reverts commit 39234e44bf.

* refactor(native-chat): make ensure-owner a step of the serialized send

A send that found the owner gone restarted it OUTSIDE the host's per-session
serialize, through a single-flight resume map shared with the surface hold, then
rebased its fence by heuristic. The attach body is now callable from inside
`serialize` (`attachStructuredAgentSessionUnderSerialize`), and every restart
runs there: a hold, a send's ensure-owner step, provider-exit recovery and the
rewind owner replacement take turns on one queue, so the first to run attaches
and the next finds its child. The single-flight map and `isResuming` are gone.

Admission is two-phase for a send: the ledger's answer comes first and places
nothing; a send it will admit gives the session an owner, and only then are the
row placed and the lease and fence checked. A send it will replay into a closed
session makes the journal readable and spawns nothing. The session entry
records the released fence the child replaced (`resumedFromFence`), so a writer
current as of that owner is admitted at the new fence by bookkeeping, whether it
ran the restart or arrived behind it.

The resume reads its record only after this host has reconciled it and exited
any recovery stage a failed attempt latched, so a hold behind a failed attempt
makes its own attempt against the lease as it now stands.

* fix(native-chat): a Claude start proving itself no longer waits on the CLI

The host handles a Claude child's `started` on the recovery chain every
session's unexpected-exit handling shares, under that session's serialized
step. It then asked the CLI for the model list and settings again, so one slow
CLI held every other session's exit recovery, and its own close, behind up to
two request timeouts.

The adapter already holds those answers when startup proves: the settings read
at startup, the restore's confirmations, and the initialize result the SDK
answers the model list from. `started` now carries that snapshot, and the host
turns it into one record write without any provider I/O.

* test(native-chat): a hold reads its lease only after this host has reconciled it and exited a latched recovery stage

* fix(claude): a chat whose first start failed resumes as the same conversation

A Claude start that dies before initialize writes no transcript, so the next
start launches the chain head's provider id fresh instead of `--resume`. The
launch flag that chose that mode also chose the provider-handle link's origin,
so the fresh launch published a second `created` link onto a chain that
already had a head. The store refused it, the healthy child was closed, and
every later reopen, hold or send spawned and killed another Claude.

The launch now carries the two facts separately: `resumesTranscript` (launch
mode, from whether Claude wrote a transcript) and `continuesChain` (lineage,
from the record's chain head). The link origin reads lineage; rewind and the
Fast opt-in carry-over read launch mode.

* refactor(native-chat): a resume answers with a typed refusal the send classifies

`resumeHeldStructuredAgentSession` and the holds' `ensureProviderChild` answer
`{ ok: true } | { ok: false, refusal }` instead of throwing the refusal code.
The refusal is the attach's own, with its message and, when the failed attach
proved its child gone, its `ownerVerdict`. An attach that settles a failed
acquisition in the ledger and then rethrows the cause is read back off that row,
so a durably failed restart is a refusal and only an unrecorded error is a fault.

The send classifies the refusal through a `Record` over every wire code — a new
code does not compile until it is placed — into transient (the lease is someone
else's to settle; the send runs as the lease stands) or terminal. A terminal
one answers `agent_session_owner_unrecoverable` carrying the cause, forwards the
verdict, and writes the same status row into the chat that a start that failed
leaves, so the user sees why after the error strip is gone. Nothing about the
failure is remembered; a Retry is a fresh attempt. A fault thrown by the restart
itself is reported and the send runs as the lease stands, since bookkeeping
never gates a user's action.

`hold()` still raises the refusal code for its RPC caller.

* fix(native-chat): a child's event sink belongs to the attach attempt that spawned it

The runtime kept one event sink per session id and handed it to every attach.
An attach that acquired a new child unbound that sink first, so when the
acquire then failed its dead child's queued frames stayed in the cached,
unbound sink. The earlier guard only discarded it when no session entry was
left, which a resume of a still-indexed session never satisfies: the next
attach's drain and shutdown's flush waited on it forever. A TUI-to-native
handoff acquire had the same shape.

Each acquiring attempt now mints its own sink. Only a successful attach (or a
proven handoff owner) adopts it as the session's, closing the one it
replaces; any other exit closes it with whatever its child queued. A re-attach
to a live child keeps the sink that child already writes through. A sink that
is not the session's own can no longer force the session's provider down.

The native handoff acquisition moves to its own module, which keeps the
handoff file under its line budget.

* test(native-chat): pin that only the adopted child's event sink still takes writes

Closing a failed attempt's sink and closing the sink a resume replaces were both
unpinned: removing either left every suite green, because neither sink is in the
map that drains and flushes read. The resume test now asserts the failed
attempt's sink and the exited generation's sink refuse writes, and the adopted
one accepts them; deleting either close reddens its own assertion.

* perf(native-chat): the chat reads only the host's startup phase from the status feed

The chat took the whole status summary to read one field, so every status change
for its session (prompt, update time, background tasks) re-rendered the chat
view. It now subscribes with the phase itself as the snapshot, so it re-renders
only when the phase changes.

* fix(native-chat): the startup-phase hook answers a phase or null, never undefined

* fix(native-chat): every restart is counted from the moment it is asked for, and a handoff clears the restart fence

Provider-exit recovery now restarts through the holds' `ensureProviderChild`
like a hold and a send do, so a child whose only surface left while the attach
ran goes on the idle clock instead of living until quit. A hold's resume and a
client attach are tracked as in flight from enqueue, not from their turn on the
queue, so a quit's drain waits for one queued behind a close before it decides
what to evict. A handoff back to native moves the fence in place and now clears
`resumedFromFence`: only a restart may rebase a writer. The failed-restart
status row is keyed by the send's operation id, not the clock, so a resend of
the same id that fails again adds no second row.

* fix(native-chat): a Claude start no longer waits behind another session's exit recovery

The runtime delivered every Claude lifecycle event on the single chain
exit recovery uses so teardown can drain it. That chain orders nothing
across sessions, and an exit recovery on it can run a full reacquisition,
so one chat's `started` waited on an unrelated chat's respawn and kept
its 'still starting' line up. `started` now takes only its own session's
serialized step, is queued the moment it is emitted (ahead of any later
exit of that child), and is tracked in a set the same teardown drain waits
on.

* fix(native-chat): a Claude create that dies at spawn is refused with the CLI's own diagnostic

A CLI that exited before its acquisition handed the child over was
refused with 'claude stream-json for session … exited while being
acquired', or with an unreadable start time, and the stderr the exit
carried (for example 'not signed in') appeared nowhere. The acquisition
now keeps the error its connection ended with and answers with it at
both sites; the generic message is only a fallback when none exists.

* test(native-chat): pin that a reopened Claude chat dying before initialize says why

A resumed start is published at spawn, so a CLI that exits before it
answers initialize fails a chat the user is looking at. Pin that the
open chat is sent the 'stopped before it finished starting' row with the
CLI's diagnostic even when the child's tree cannot be proven gone, and
that a message held for that start is refused rather than left in doubt.

* fix(native-chat): Stop while a Claude start drains its held prompts withdraws the rest

Stop withdrew held prompts only while startup was pending. Once startup
landed and the gate began writing them one by one, a Stop interrupted the
CLI and the prompts still waiting were written straight after it. Stop
now withdraws whatever the gate still holds in both states; the drain
takes each prompt off the queue immediately before writing it, so a
withdrawn prompt can never be written. The one already written still
gets the interrupt.

* fix(native-chat): the release clock keeps a session that still owes a sent message

When the last surface stops holding a session, the release clock evicts
it after the grace unless a turn is running. A message sent while Claude
is still starting is held, not running, so switching away from that chat
for the grace evicted the session and refused a message the user had
already sent. The clock now asks whether the session owes work: a running
turn, or a submission the provider has not taken yet (still pending in
the journal). Both are read from the journal; nothing new is stored. A
starting session that owes nothing is still released, and an explicit
close still ends everything.

* fix(native-chat): only a start that holds a sent message keeps a released session

The release clock kept any session with a pending submission. A Codex
send is admitted and stays pending until its echo, which may never come,
and only an eviction retires it, so such a session was never released
while the app ran. A pending send now keeps the session only while its
child is still starting, which is when the send is held for that start.
Pins that a ready session with an unechoed send is evicted, and that a
Claude chat whose turn finished is released after the grace.

* fix(native-chat): a send waits for the owner it met to prove its start before it is admitted

A Claude child is published before the CLI has answered initialize, so a send admitted right
behind a restart — or right behind the first start — was dispatched into a child that could die
milliseconds later, and learned of the death only as a delivery nobody could confirm. The terminal
refusal the send was written to give was unreachable on the real adapter for exactly the failure
it was written for.

The send's serialized step now admits nothing against a `starting` child. It registers for the
child's startup verdict and returns having placed nothing; the send waits off the session's queue
(the `started` and `ended` settlements run on it) and admits again once the child is `ready`, or is
refused `agent_session_owner_unrecoverable` with the child's own exit reason when it exits first.
The exit settlement writes the one status row, decided by the host's own phase rather than only
the provider's flag. A close, an eviction or a replacement answers the wait too, and quit releases
whatever is left; there is no timer. One spawn per user action holds across re-entries.

* fix(native-chat): restart the release grace when a start writes its held prompts

A prompt held while Claude starts is written when the start lands, but
its turn opens only when Claude echoes it. The release clock stopped
counting it once the child read ready, so a tick landing in that gap
stopped the child before it ran the user's first message. The start
landing now restarts a pending release's full grace, the same grace a
message sent to a ready chat gets before it is released.

* fix(native-chat): a starting child owns the send; the adapter holds the message for its start

A send that meets a child still proving its start is admitted against it, as it was before the
off-queue startup wait: the adapter holds the message until startup lands and rejects it with the
child's own diagnostic when the child dies first, the exit settlement writes that cause into the
chat, and the release clock keeps a starting session that holds a sent message. The startup watch,
the off-queue wait loop and their teardown phase are gone; the exit settlement still reads a start
that failed off the host's own phase when the provider omits the flag.

The scripted-CLI test now pins that contract end to end: a restart a send asked for whose CLI dies
at initialize leaves the message rejected with the diagnostic, one row naming it, and the fence
moved by two; a healthy CLI is restarted once and written to; a send during the first start is
held and written once initialize answers, or rejected with the diagnostic when the CLI dies.

* fix(native-chat): a failed send restart says why, and offers a new chat only when nothing can restart it

The refusal a send gets when the host cannot restart the chat's agent is renamed
agent_session_owner_restart_failed and now reads "<Agent> couldn't restart: <reason>." with the
restart's own cause. "Start a new chat to continue." is added only when the resume was refused
because this host has no record to restart from or cannot run the one it has. Any other failure,
such as a CLI that is not signed in, leaves the chat retryable: the outbox stops auto-retrying, and
a manual Retry or a new send tries the restart again, since a refusal before admission leaves no
ledger row.

* fix(native-chat): a Claude start skips an option write the CLI never answers instead of faulting at the request deadline

* test(native-chat): wait for the recovery's reserved lease, not the released one it replaces at once

* fix(native-chat): a send whose restarted child dies before starting is rejected with the child's diagnostic

A child that never proved its start has accepted nothing: input is written
only after it initializes. A send admitted against such a child, whose
dispatch then found no session, settled unknown, twice, and the outbox took
Retry away. It now settles rejected with the child's own diagnostic, both
when the dispatch throws and when the exit settles the sends it left
unanswered, so the chat says why and offers Retry. A proven child's
unanswered sends stay in doubt, as before.

* test(native-chat): expect a send held for a start that never proved itself to settle rejected

* fix(claude): write a prompt held after startup already drained, instead of stranding it pending

* test(native-chat): pin that a send to a child that died before starting is answered rejected

* test(native-chat): leave the cast exit-session fixtures as they were, since a proven exit never rejects

* fix(claude): a saved option the CLI never answered stays saved instead of being replaced by the CLI's value

A start skips an option write the CLI does not answer within the request
deadline, and then persisted what the CLI reported in its place, so a slow
answer silently replaced the user's saved model or dropped their saved
permission mode. Silence is not a refusal: the unanswered option is now
recorded apart from a rejected one, the live child keeps running on the
CLI's value, and the saved choice stays on the record for the next start to
retry. An option the CLI rejects is still dropped as before.

* fix(native-chat): a rejected send opens no turn, so the row naming why it failed is not folded away

A send whose restarted child died before starting is rejected, and the
exit writes a row naming the cause. The chat's local clock had watched the
send go pending and stop, so it gave the message "Worked for 0s"; that
settled a turn that never ran, and the fold hid every non-prose row after
the message behind it, including the one naming the cause. The row only
appeared when a later send moved the turn anchor, which read as two rows
for one Retry. The host's journal already says the send was rejected; it
now answers that such a message opened no turn, which outranks the local
clock on desktop and mobile alike. A rejected send whose journal does
record a turn keeps its duration.

* fix(native-chat): a send whose restart died starting leaves the same row as any start that died

One failed attempt already leaves one row, but which row depended on when
the child died. A child that died after the send was admitted left "The
provider stopped before it finished starting: <cause>."; one that died
before the send was admitted left "Claude couldn't restart: <cause>." So the
same failure read two ways from one Retry to the next. When the refused
restart proved its child exited, the send now writes the startup-failure row
itself, as its comment always said it did. The refusal under the composer
still says the restart failed; a restart that failed for a reason other than
a child exiting keeps its own wording.

* fix(native-chat): a send rejected because the agent never started names the cause under the composer

When the child a send was admitted against died before starting, the host
rejected the send with the child's diagnostic behind the internal transport
marker. The client rightly hides that marker's detail, so the red line read
"Couldn't reach the agent" while the cause sat in the record. A startup
death is not a failed write: the host now words that rejection the way the
chat row does, "The provider stopped before it finished starting: <cause>.",
at every site that rejects for it. Desktop and mobile show a reason in words
verbatim already, and older clients do too, so no client change is needed.
Real write failures keep the marker and the generic copy.

* fix(claude): a saved option the CLI never answered survives a later change to a different option

The saved choice a start could not apply was kept on the record, but the next
option the user set persisted only what the child had applied, so changing the
permission mode or effort, or clearing the chat, silently dropped the saved
model. The adapter now reports which saved options are still unanswered, every
option write keeps those saved values, and a write the child accepts for that
option retires it.

* fix(claude): a send that meets a child whose exit already settled names that exit's cause

When the child a send was admitted against died starting and its exit
finished settling before the send reached it, the send was rejected with
"no live claude stream-json session for <id>", now shown under the composer
as the cause. The adapter keeps a settled exit's diagnostic until the chat is
acquired or closed again, so that send names what the CLI said. A refused
restart whose child died at spawn or while its start time was read is pinned
to leave one row in the words any failed start uses.

* test(native-chat): pin the words an exit settlement rejects a never-started send with

The startup gate and the dispatch reject a send first in every existing
scenario, so the exit settlement's own rejection had no test of its wording.

* fix(claude): derive which saved options are still unanswered from what the child applied

A write that lands already puts its option in the session's applied set, so
the unanswered list is that list minus what has since been applied, rather
than a second copy every option write must remember to edit. Session
fixtures built without the new set no longer throw on an ordinary write.

* fix(native-chat): a cleared chat starts from a saved choice the child never answered

Clearing a chat seeded the replacement from the values the child reported,
so a saved model or effort whose restore write the CLI never answered was
replaced by the CLI's own value in the new chat, even though the retired
record kept it. The replacement now keeps those saved values too, and its
start retries them.

* fix(claude): closing a chat forgets its exit's diagnostic even when the exit settles during the close

The diagnostic was dropped when the close began, but closing over an exit
that was still settling finishes that settlement, which kept it again, so a
closed or deleted chat held it until its next acquire. It is now dropped once
the close finishes. Pins that an acquire and a close each retire it.

* refactor(claude): keep a saved option the CLI never answered as the wanted value, not a list beside it

A restore cleared the session's wanted options and added back only the writes
the CLI answered, so an unanswered one lost the user's value and every later
writer had to be told to put it back: the start report, each option change and
/clear each carried a list of unanswered keys. The restore now keeps the saved
value as wanted and unconfirmed, so what the session reports and persists
already carries it, and the list, its adapter method and the started-event
field are gone. A refused option is still dropped.

/clear now starts the replacement from the record's options instead of reading
the child's live values, which can be a model the CLI fell back to.

* test(claude): wait for the start to finish before changing the saved model

The record holds the saved model from creation, so waiting for it returned at
once and the option write could reach Claude while it was still starting,
which refuses it. Wait for the effort the finished start reports instead.

* fix(i18n): translate the still-starting chat notice

The notice that a structured chat is still starting was only in English.

* test(claude): pin the failed acquisition's own reading-control release

The merge re-pointed this test at a child that exits after publish, where the
exit path also releases the binding, so it passed with the acquisition's release
deleted. A child that exits before publish leaves only that release. Also drops
the create 'init' phase, which lost its last producer when rewind stopped
proving before publish.

* refactor(claude): move unexpected-exit handling into the exit lifecycle module

The adapter crossed the 300-line limit once main's context-usage change
landed beside this branch's growth. The two methods that turn a Claude
process exit into an ended event now live next to the existing exit
helpers; behavior is unchanged.

Brennan Benson f0b3f44f10 feat(agent-session): let the host own a chat's tab id and let a create reserve it (#22616)
* feat(agent-session): let the host own a chat's tab id and let a create reserve it

A structured chat's tab id was derived from its session id by every layer that
needed one: the renderer, the host snapshot and the status address each built
their own spelling. The join between a conversation and the tab that shows it
must be a pointer the host owns, not a derivation each client repeats.

The session record now carries surfaceTabId. A create pins it: the tab half of
the pane agent.launch reserved, an optional tabId on agentSession.create, or a
host-minted UUID. Records written before the field existed are backfilled at
open with the string clients derived, in memory at once and on disk with the
store's first transaction, so nothing keyed by it (read state, notification
ids, worker rows) moves on upgrade. A second record under a held id is refused.

Only the record and the two create wires change here. The snapshot still
publishes agent-session:<sid> and the renderer still derives its local id;
those move in the next two changes. agentSession.create is a strict object, so
the field is advertised as a capability a client checks before sending it.

* fix(agent-session): record the derived tab id for an unreserved create

A create that reserved no tab minted a random UUID that no reader uses: the
renderer, status address, worker rows and host-shared read state all still key
by structured-agent-session-<sid>. Persisted, that id would move every chat
created before readers switch to the recorded one, orphaning its read state
and worker rows the way the backfill exists to prevent. An unreserved create
now records the derived id, the same rule the backfill applies, so the record
always matches the prefix every existing key uses; an opaque mint belongs with
the change that moves the last reader.

Also:
- a chat tab id must be a host tab id on the record, the create wire and in
  admission, matching what agent.launch already requires of paneKey; a
  web-surface id would decode as another tab
- the stored launch-result guard checks the structured outcome's tabId
- comments no longer claim a retry naming another tab conflicts; replay keys
  on the attach fingerprint and answers with the recorded id (now pinned)
- the wire refusal test used a non-hex digest, so the schema refused it for
  that reason; it now reaches the tab id rule
- pin that the reload path refills the id without forcing a save

* test(agent-session): correct the tab-id fingerprint comment to match replay

Brennan Benson 25d7c21fcb feat(native-chat): show context window usage in the composer (#22301)
* refactor(native-chat): move the composer's stop action into its own hook

The composer is at its line budget; lifting the stop action out makes room
for the context usage ring without changing what Stop does.

* feat(native-chat): record the Claude CLI's context window facts on the structured journal

A structured Claude session now keeps what the CLI says about its context
window on journal rows, so every client reads the same answer and a restart
replays it:

- Each main-thread assistant response keeps its API usage. A subagent's
  response measures its own window, so it carries none.
- The turn a result settles records the session's window: the largest
  contextWindow across the result's per-model usage, since side calls to a
  smaller model report their own smaller window.
- After a result and after a compaction boundary the host asks the CLI for
  its /context breakdown (5s bound) and records the answer on the current or
  last turn. An answer is dropped when the main conversation moved, a send was
  accepted, a newer request was issued, or the session was released while it
  was in flight; a failure or an older CLI leaves the row unchanged.
- A compaction boundary or conversation reset records that the used count is
  unknown until the next response or report, so the pre-compaction size is
  never shown as current.

Every part carries its own host clock, and the reader takes the newest, since
a revised turn row keeps its place in the transcript. The persisted validator
admits every value the writer can write, including a zero auto-compact
threshold: a row replay rejects truncates the journal from that row.

* feat(native-chat): show context window usage in the composer

A structured Claude chat shows a ring beside send once the journal can state
the session's context usage. Hovering shows used/window with a bar and, when
the CLI has reported its breakdown, one row per CLI category as a share of the
window, largest first. Between reports the ring shows the newest response's
usage against the newest window the CLI reported, marked as estimated. Before
the CLI has reported any window, and after a compaction or reset until the next
response, there is no ring. A terminal-backed chat shows none.

* fix(native-chat): measure the context ring against the main thread's model window

The result's per-model usage is cumulative across the session and includes
subagents and side calls, so the largest window was often not the one the
main conversation runs in: after switching from a 1M model to a 200k one, or
when a subagent ran on a larger-window model, the ring read against the
wrong window after every turn. Pick the entry named by the model that served
the newest main-thread response, and among its [1m]/non-[1m] entries the one
the result moved; fall back to the largest only when nothing names it.

* fix(native-chat): keep the context ring moving through tool-only responses

The live estimate lived on assistant message rows, and a response with only
tool calls or thinking writes no message row, so the ring froze through long
tool loops and stayed hidden after a mid-turn auto-compaction until the next
text reply. Record every main-thread response's usage on its turn row
instead, once per response, so the selector sees each one.

* fix(native-chat): read the ring's window from the model the turn's init names

The CLI keys per-model usage by the main loop's model string, [1m] included,
and every turn's system/init frame carries that exact string, while a
response drops the suffix. Match the init's key first, so a session that
switched between the 1M and 200k variants of one model reads the right
window; fall back to the newest response's model, then the largest entry.

* fix(native-chat): correct the composer's control-order note for the context ring

* fix(native-chat): keep a running turn's context facts when the host settles it

A turn row now carries the live context estimate while it runs. When the host
settles a running row itself (a crashed or stale generation, a close the
translator never saw), it rebuilt the record field by field and dropped those
facts, so after a crash the ring fell back to an older turn's size, or to a
pre-compaction size the dropped reset had superseded.

* refactor(native-chat): revise Claude turn rows from the journal so the ring survives a restart

The context ring's facts were written to turn rows through an in-memory list
of recent turns. A new translator is built on every acquisition, so after a
restart or reattach that list was empty and every fact for a turn that was
not open was dropped: a /compact as the first action after a restart never
cleared the ring and never showed the fresh breakdown.

Every Claude turn-row write is now a revision of the row as the bound journal
holds it when the write runs. The sink gains a resolved revision that reads
the target row and its body at execution; the queue runs one operation at a
time, so the read-modify-write cannot interleave, and revisions are never
coalesced. Lifecycle writes own the lifecycle fields and context writes own
contextUsage; each keeps every other field. Only the open turn is kept in
memory. A fact with no open turn lands on the newest turn row, and a report
lands on the turn it was requested for.

The persisted facts are simplified to a window, which now names the model it
was measured for, and a single used part (report, estimate or unknown) that
each write replaces. The ring reads the newest turn row carrying each part,
and hides an estimate whose model the window was not measured for instead of
dividing by another model's window. A turn opening, and a reset, count as
activity, so a late report can never land behind a newer turn.

Host settlement of a stale running turn now drops only the fields its verdict
owns, so context facts and any field a newer build wrote survive it.

* fix(native-chat): keep a turn row whose context facts this build cannot read

Context facts are validated deeply, so one malformed or future-shaped fact
made the whole turn row malformed, and replay truncates the journal from that
row on. Replay now drops unreadable facts from a turn row, in item rows and in
settlement batches, and keeps the row, the same way it already drops producer
linkage it cannot trust. The ring shows nothing for that turn instead of the
session losing its history.

* test(native-chat): pin that a child exit mid-turn keeps the ring's last size

A lifecycle-only revision, the end a turn gets when its child exits without a
result, must keep the context facts the row already carries.

* perf(native-chat): revise a named Claude turn row by key instead of scanning the journal

Every Claude turn-row write walked every reduced journal item to find its
row, even when it already knew the row's identity, so a long session paid
O(items) per write on the main process. The journal now answers a keyed read,
and a context report names its turn by row identity rather than turn id, so
only a write made while no turn is open still scans.

* fix(native-chat): tell a 1M window from a 200k one of the same model

Responses drop the [1m] suffix, so after a switch between the 1M and 200k
windows of one model the running turn was measured against the previous
turn's window until its result arrived. An estimate now records the turn's
init model, which keys the window exactly, and the reader requires the full
model id to match.

* fix(native-chat): show no ring for a context kind a newer host writes

A paired client reads turn rows from the host unvalidated, so a used-count
kind this build does not know fell through to the estimate branch and threw
reading its missing usage. Only the kinds this build can measure now produce
a ring.

* fix(native-chat): keep the context ring through plan-mode turns on another model

Plan mode can run a turn on a model the turn's init does not name (opusplan
upgrades to Opus's 1M window). The estimate then carried only the response's
id, which drops [1m], and the exact comparison against the window hid the ring
for every plan-mode turn. The estimate now records the response's id beside
the init's exact key, and the reader matches the base model only when no exact
key was recorded.

* refactor(native-chat): pair the context ring's window by model change, not by model id

The ring divided the newest response's size by the newest window only when
their model ids matched, which meant comparing ids from the init frame, the
response, per-model usage keys and canonical ids. Those disagree in plan mode
and across 1M and 200k windows of one model.

The writer now knows when the model may have changed: after a model or
permission-mode write that changes the value, when a restore cannot put the
stored model back, and when a main-thread response comes from a different
model than the one the window serves (an approved plan). It then marks the
size unknown, holds estimates, and asks the CLI for its context report, which
states the new model's window. Any new window, from a report or a turn
result, releases the hold. The reader compares nothing: a report, or the
newest estimate over the newest window.

Turn rows no longer store window.model, window.canonicalModel,
estimate.model or estimate.responseModel.

* fix(native-chat): keep a late context report's window when only its count went stale

* test(native-chat): pin that each turn's init lets its result restate the context window

* fix(native-chat): open the context card on click and tap

* fix(native-chat): wait a beat before a mouse hover opens the context card

* fix(native-chat): publish each context write in the operation that makes it

A context report answers after the turn's last frame, so a revision that waited
for the next frame's publish reached live clients only on the next turn. Context
writes now queue their revision and its publication as one operation.

* fix(native-chat): write million-token counts with a capital M

A lowercase m read as minutes on the context card.

* fix(native-chat): keep the context card open while the pointer crosses into it

The card closed the moment a mouse left the ring, so the pointer could not
cross the gap into the card. Leaving now waits a beat, and entering the card
cancels the close.

* fix(native-chat): let Escape close the context card without stopping the agent

The card keeps focus in the composer, so the Escape that closed it also
reached the composer and interrupted the running turn. The composer now
skips an Escape an open layer already handled.

* fix(native-chat): show the context ring when the chat has not loaded the turn it belongs to

The ring read context facts only from the rows the chat had loaded, so a
reopened chat whose recent page started after the last turn row, or a live
turn longer than the retained window, showed no ring until the next turn.

The host now derives the newest context facts from its whole journal with
the same selector the chat uses, and returns them on agentSession.options
for sessions that write them. The chat prefers each fact its loaded rows
carry and takes the host answer for a fact they lack. When a live batch
revises a turn row older than the loaded window, the chat asks for options
again so that answer stays current.

* fix(native-chat): bound context refresh reads and refresh when the turn row is trimmed

Each turn-row revision the loaded window missed started its own options
read. Those reads share the session's host queue with sends and interrupts,
and each asks the CLI for its settings, so a burst could pile reads in front
of a user action and discard every answer before it landed. The chat now
keeps one options read in flight and at most one behind it.

A live turn longer than the retained window also lost its turn row to the
trim without asking for a fresh host answer, so the ring fell back to the
answer read at turn start until the next response. Trimming a turn row now
asks again, like a dropped revision does.

* fix(native-chat): show the context ring from the first response, sized from the session's model

A new session has no measured window until its first result, so the ring
stayed hidden for the whole first turn. The host now keeps the window the
applied model's name implies (1M for a [1m] name, unknown for default, 200k
otherwise) and writes it beside an estimate when the journal holds no window,
or after a model write, until the result or the CLI's report replaces it.

* fix(native-chat): imply a context window only from a [1m] model name

A bare model name does not fix the window: first-party runs today's opus,
sonnet and fable models natively at 1M while a gateway or cloud provider runs
them at 200k, and opusplan and haiku run another model in plan mode. Sizing
their first response at 200k read the ring about five times too full, so only
a [1m] name implies a window now; any other name waits for the result.

* fix(native-chat): size the first response from a report taken before any turn

A model picked in a chat with no turn yet asks the CLI for its context
report, but with no turn row the report's write lands nowhere. Recording it
still marked the journal as holding a window, so the first response wrote
none and the ring stayed hidden until the turn's result.

The report's window now serves as the fallback a response writes while the
journal holds no window, and recording a report no longer assumes its write
landed.

* test(native-chat): move the fake Claude connection out of the structured integration suite

The context-report delivery case pushed the suite past the 800-line limit,
failing repo-wide lint. The fake child now lives in its own fixture.

Brennan Benson 80f5aae0f9 feat(agent-status): publish the main agent's own state beside the combined row state (#22452)
* feat(agent-status): publish the lead agent's own state beside the combined row state

Every status producer folded the main agent's state together with live child
work into one `state`, so a lead that had finished while a subagent still ran
read `working` and its own state was lost. The row now also carries
`lead: { state, outcome?, stateStartedAt }`, admitted by the one payload
normalizer on the relay wire, IPC and disk, and published from the Claude hook
lane, the structured host ingest and renderer bridge, Grok (now on the shared
fold) and Codex (own combine kept). The persisted child-only boundary flag is
derived from `lead` plus child evidence and no longer written; old rows map
onto `lead` at hydrate. Combined `state` and `workingMode` are unchanged for
every reader; a cross-lane parity table pins that, with the cancelled-turn
watch-loop story recorded as a known divergence.

* fix(agent-status): make Orca's inferred interrupt the primary source of a Claude lead cancellation

Current Claude Code sends no hook at all on a cancel and no is_interrupt on
Stop, so the cancellation enters the lead record from the server's inferred
interrupt and rides into the next real Stop; is_interrupt on a turn boundary
stays as the secondary source for builds that send it. Comments, the store
reference and the parity table say so; no suppression changes.

* docs(agent-status): the child-only boundary comment now describes the persisted shell fact

The old sentence said a hydrated row no longer carries the shell fact, which is
the opposite of the mechanism: claudeRunningNonAgentTask is persisted precisely
so hydration can read it, and only a pre-lead row lacks it — reading as
shell-free, the same assertion its legacy flag made at write time.

* rename the lead fact to mainAgent: the main agent's own state

* docs(agent-status): the inferred cancel comes from Ctrl+C, not Esc

* fix(agent-status): an inferred interrupt keeps an already settled main agent, and the row verdict docs name its inferred source

* fix(agent-status): a child-induced wait publishes the main agent state it displaced

* fix(agent-status): decide child-held Claude rows from the saved main agent fact

Restart seeds the Claude main agent from the row's saved mainAgent whenever it
settled and no shell held the row, instead of re-deriving a child-only shape.
OSC cannot settle or repaint a row child agents hold open, including a row
waiting on a child's permission prompt. A sticky child permission prompt still
records the main agent's own progress, and OSC repaints and inferred answers
keep the shell fact beside the main agent they preserve.

* fix(agent-status): keep a finished turn's main agent verdict and clock with that turn

A Claude SessionStart restarts the main agent's clock instead of inheriting the
previous session's last Stop. A Grok idle prompt or session end, and a late
Codex root Stop after an inferred cancel, restate the same finished turn, so
they keep its recorded verdict; only a new turn clears it.

* test(agent-status): publish the Grok verdict restatement past the late-event window

* docs(agent-status): describe hydrate seeding and the OSC refusal from the saved main agent fact

* fix(agent-status): push a held child permission row when its main agent changes

* fix(agent-status): keep the shell fact on a held child permission row so restart does not settle it

* docs(agent-status): note the held child permission row carries the shell fact and is pushed

* fix(agent-status): pair the Claude shell fact with the main agent at the one row-build point

Every non-hook rewrite (terminal-title repaint, inferred answer, held child
permission) had to re-carry the shell fact beside `mainAgent`, and each one that
forgot let a restart settle a row while a shell still ran. The row builder now
pairs the fact once: a listener event restates it, any other write keeps it only
while `mainAgent` is unchanged. Restart seeds a settled main agent only when the
row says no shell ran, and legacy child-only rows map to that explicitly.

A held child permission now also accepts the main agent event's background
evidence, as it already accepts its `mainAgent`, so the child's drain no longer
settles a row a shell still holds. The renderer keeps a previous `mainAgent`
only for writers that never carry one, so a hook row without it matches the
host snapshot.

* test(agent-status): pin that restart never seeds a main agent from a row silent about its shell

* docs(agent-status): the row builder pairs the shell fact with the main agent, and restart seeds only on an explicit no-shell

* test(agent-status): name the legacy-row case parameter for what it holds

Brennan Benson 563dd5487f feat(native-chat): show a Codex chat's goal above the composer, and set it from goal mode (#22377)
* feat(native-chat): show a Codex chat's goal above the composer and set it from goal mode

Structured Codex chat now treats the thread goal as session state: a banner above the
composer shows the current goal (pursuing / paused) with clear, pause/resume and expand;
/goal enters a goal mode whose send calls thread/goal/set; the objective is journaled as a
user message marked as sent as a goal. The banner is derived from the journaled goal rows,
which Codex's resume snapshot refreshes, so a reopened or adopted chat shows its goal.

Fixes STA-8159

* fix(native-chat): replace a recorded goal by clearing first, and recover a lost goal-change response

- A set while the journal records a goal (any status) clears it before setting,
  so the new goal starts with its own time and token counters instead of
  rewriting the old goal's objective in place.
- The threadGoal plan answers an unknown outcome from the goal the journal
  records and reruns otherwise, so one request timeout no longer refuses every
  later Clear/Pause/Resume as unknown for the mounted session.
- The goal-mode chip says "Exit goal mode"; "Clear goal" stays the banner's
  action on the provider goal.
- A typed bare /goal on Enter enters goal mode, the same as picking it.
- The renderer reads the goal off the tail of its ordered snapshot; the host's
  unordered map keeps the by-sequence reader.
- Drop the composer's duplicate in-flight guard; the goal controller already
  serializes changes.
- Pin that a counter-only revision reaches a subscriber's live page under its
  original sequence.

* fix(native-chat): keep a bare /goal inside goal mode as the entrance, and pin goal delivery and serialization

- A bare `/goal` submitted while already in goal mode re-enters the mode instead
  of setting a goal whose objective is the literal text "/goal".
- The counter-only revision pin now drives the host's own event sink bound to a
  real journal, so it goes red when the publish after a lifecycle transition is
  dropped; the previous fake sink never published.
- Pin that a set which threw after journaling its objective puts that objective
  back exactly once when the ledger reruns the same operation id.
- Cover the goal controller hook: absent without host support, the loaded window
  wins over the host's answer, a second change while one is unsettled answers
  false without a request, and a refused change frees the next one.

* fix(native-chat): resume a blocked or usage-limited goal, and keep goal-mode drafts honest

- The goal bar offers Resume on a blocked or usage-limited goal, which the
  provider resumes exactly as it resumes a paused one; a goal whose token budget
  is spent still offers only Clear. The rule lives beside the other goal facts
  in shared code so every reader answers it the same way.
- A `/goal <text>` typed inside goal mode sets the objective `<text>`, as it
  does outside goal mode, instead of a goal whose objective is the literal
  command.
- Setting a goal is a host round trip; a draft edited while it was in flight is
  no longer wiped when the goal lands, matching every other host command.
- Pin that a lost status-change response is read as applied only when the
  recorded goal is in that status, that a cleared row in the loaded window
  outranks the host's earlier answer, and that the PTY lane is untouched.

* fix(native-chat): keep the load-older anchor on the loaded window when a live revision lands below it

A live revision of a row keeps that row's original sequence. When the row is
older than the client's loaded window, the shared reducer merged it in and it
became the load-older anchor, so paging `before` it skipped every row between.
A goal's counter-only revisions during a long goal turn reach any client that
attached after the goal row left its window, so a reopened chat lost rows on
scroll-back.

The reducer now admits live rows only at or above the window's oldest row
while older rows remain on the host; the journal keeps the revision and the
page reader serves it once the window reaches the row. With nothing older on
the host the window is the whole journal, so a row below the head is admitted
as before.

Also drain accepted provider events before a goal set reads the journal to
decide whether it replaces a recorded goal.

Brennan Benson 8757e40063 fix(native-chat): keep a structured agent's tool line between tool calls (#22349)
* fix(native-chat): keep a structured agent's tool line between tool calls

A structured session's status named a tool only while the call was still
running, so the sidebar's tool line went blank whenever the agent was
thinking or writing between calls. Terminal agents keep naming the finished
tool until the next one starts, and clear it after a failure. The structured
status projection now does the same: a running call wins, otherwise the
turn's newest root call if it completed.

* fix(native-chat): bound the structured tool line by the running turn, not the user row

A send made while a turn is running writes its user row into the journal
straight away, and the turn keeps going. Stopping the scan at that row
blanked the tool line while a tool was still running. The scan now runs to
the turn record and names a call only when that record is still running, so
a turn that already ended never lends its last tool to a pending follow-up.

This lookup was the running-only lookup's only production caller, so it
replaces that lookup instead of sitting beside it.

* fix(native-chat): keep naming a structured agent's failed tool until the next one

Clearing the tool line after a failed call brought the blank gap back for
much of a turn: Codex marks any nonzero exit as failed, so a search with no
match or a red test run is enough. The failure already shows on the tool's
own row in the transcript. The running turn's newest running call still
wins; otherwise its newest root call is named whatever it settled to.

* fix(native-chat): name a structured Codex edit on the tool line as the chat draws it

Once a Codex edit's changes exist, its apply_patch call becomes a diff row,
which the status lookup skipped, so the row named the command before the edit.
The chat's tool-call block for a journal row now comes from one shared builder,
and the status lookup reads the same definition: a diff is named as Diff with
its path, and counts as settled since it carries no lifecycle.

* docs(native-chat): describe the structured tool field as running-or-latest

The status summary's toolName/toolInput now name the running turn's
latest tool between calls, not only a running one. Update the wire type
and status bridge comments that still said "the running tool".

Brennan Benson 2739246058 feat(native-chat): light the unread indicators when a structured chat finishes (#21924)
* feat(native-chat): light the unread indicators when a structured chat finishes

A structured native chat had no attention producer. The PTY lane reaches the
unread markers through use-notification-dispatch, whose liveness reads PTY
state and whose admission requires terminal panes, so a structured session —
which runs on the execution host with no renderer PTY — could finish a turn
with nothing lighting anywhere. A backgrounded chat was the worst case: with
no mounted pane there was no reader to notice at all.

The host derives the completion, because only the host can. The journal keeps
committing whether or not a renderer holds a reader, so the new feed observes
each commit at StructuredAgentSessionClientDelivery.publishJournal and emits on
every running -> settled transition. That edge runs after the subscriber loop
and independent of it, which is exactly why a chat nobody is watching can still
complete. It is a separate capability-gated stream rather than a field on the
status summary: the summary carries no turn identity and no outcome, and is
re-broadcast on every status change, so folding a completion into it would make
every status consumer a completion consumer.

ONLY `success` LIGHTS ANYTHING. Outcome is A0's provider verdict and is never
inferred: a turn the host merely watched stop carries no outcome and produces
no event, because absent means UNKNOWN. `completed` alone proves nothing — a
provider reports its own API error as a finished turn — so the host emits
nothing for it and the renderer filters again on the way in.

RECOVERY IS LIVE-ONLY. Nothing is retained, queued or replayed on either side.
A subscriber learns what settles while it is subscribed and nothing else; on
reconnect it re-opens an empty stream and whatever landed during the gap is
gone. A retained completion would be a durable "unread is owed" obligation with
nothing to retire it, and a reconnect would then light the dot for work the
user already read. Tests on both sides pin this so a later refactor cannot
quietly turn it into catch-up.

The dot itself reuses the neutral policy in attention/agent-attention-policy
and #21274's structured surface adapter, so suppression, acknowledgement and
addressing keep exactly one implementation and the surface key is never omitted
to evade a check. No second suppression rule is introduced. OS delivery is
deliberately not wired: this calls applyAgentAttentionUnread, not
applyAgentAttention.

Also narrows the completion feed's journal dependency to the newest-turn reader
it actually uses, and adds journal.newestTurn() beside the existing
activeTurnId() on the one shared by-sequence scan rather than a second scan.

* test(cross-version): register the turn-completion subscribe on the wire manifest

The cross-version gate asserts the structured surface's method list by name and
count, so an additive method has to be declared there deliberately. Adding the
entry makes the suite call it in both skew directions and stubs the host side,
which is the statement the gate exists to force.

Brennan Benson c287a5d9b7 feat(native-chat): add provider-aware Fast mode (#20506)
* feat(native-chat): add provider-aware fast mode

* chore: drop unrelated formatter churn from the merge

pnpm format reflowed pnpm-workspace.yaml quoting and a source-scan test
that this PR does not otherwise touch.

* fix(native-chat): review fixes for provider-aware fast mode

Review pass over the Fast mode work.

Claude reads its model catalog once per option write. The admit check, the
effort guard and the Fast guard each took their own `list_models`, so a model
write with Fast on paid two round trips for one list and let two guards answer
from two different catalogs. The guards are now pure over a single read.

Claude no longer refuses a Fast enable when the catalog identified nothing at
all. An empty list is not evidence against a model -- the same rule the model
admit-check already applies -- so a CLI that cannot answer would otherwise have
Fast refused on every model. A catalog that did list the model and stayed silent
about Fast is still not positive evidence and keeps refusing.

Codex refuses a direct `serviceTier` write instead of accepting one the next
turn discards. The turn derives the tier from `fastMode`; the key still restores
so a session persisted before Fast existed migrates.

Both option surfaces return a cached snapshot again. `SessionOptionsSurface` is
read through `useSyncExternalStore`, whose contract is a stable snapshot, and
rebuilding it per call breaks that for any consumer wired that way.

Also records two decisions that were emergent rather than stated: routing
Standard when Fast is on but no tier is named yet, and what a readback
disagreement does and does not prove.

Quality gate: merges the duplicate imports static analysis flagged, adds SAFETY
rationales for two pre-existing casts the changed-code gate now sees, and drops
a new assertion in favour of a checked narrowing.

* fix(native-chat): read Claude Fast state from the session frame

A fresh Claude session reports `fastModeState` while the settings readback still
has no `fastMode` boolean, so the two are not redundant -- the frame answers at a
moment the boolean has none. The picker fell back to "value unknown" and asked
the user to disambiguate what the provider had already reported, and the state it
reported had no reader at all.

Falls back to the frame only when neither a pick nor the settings readback
answers. `cooldown` throttles routing rather than clearing the pick, so it reads
as on; reading it as off would flip a control nobody touched.

Display only. The launch seed is untouched: an unset Fast preference still seeds
nothing, which its own guard continues to pin.

* perf(native-chat): skip the model catalog read when turning Fast off

Turning Fast off needs no support evidence, so the read only cost a
round trip — and restore replays a stored `false` on every acquire.

Also narrows the alias-matcher comment: the effort and admit guards
match on alias and resolved id only, so calling it the sole matcher
overstated it.

* fix(native-chat): clear a Claude Fast block once the child stops reporting it

The child omits fast_mode_disabled_reason entirely when nothing blocks Fast
and never sends a null, so requiring the key back latched the first reason
for the session's life: switching to a model that disallows Fast and back
retired the control for good, leaving a session running Fast with no way to
turn it off. A frame that reports state without a reason is the all-clear.

* test(native-chat): cover the mobile structured option hook

useMobileStructuredAgentOptions gained generation fencing, a pending-write
guard and a post-write options refresh with no test file. Pins the concurrency
contract and the fast mode round trip:

- a superseded options read is dropped instead of overwriting newer state
- an overlapping write is refused and the pending guard is released after
- an accepted same-fence write reads options back and applies the result,
  and a different-fence write does not
- a boolean fastMode pick reaches the wire encoded and is remembered decoded
- no Fast row when session support, catalog support or the model capability
  is missing

Each behaviour was ablated against the production logic to confirm it fails
without it. No production code changed.

* feat(native-chat): render a boolean session option as one toggle

On and Off were two radio rows under a header repeating the option name,
so a binary choice cost three lines and two clicks to read. It is now a
single switch row that owns its label, on desktop and mobile.

An unknown value keeps its caption: a switch cannot say "unset".

* fix(native-chat): resolve a boolean option's display value at the producer

A boolean session option reached the UI in three states while its control had
only two, so the renderer apologised for the gap with a "Current value unknown"
caption beside a switch that had already collapsed to off. For `thinking`, whose
catalog default is on, that caption sat next to a switch asserting the opposite
of what every composed dispatch assumes.

One expression fed both the displayed value and the option's provenance. Split
them: the boolean descriptor now always carries a value, resolved to the same
`values[id] ?? defaultValue` that buildNativeChatSessionOptionCommand already
composes, while `valueSource` is untouched and still records whether anything
confirmed it. `kind.currentValue` is required on the boolean arm so the third
state cannot come back.

The launch path is unaffected: resolveAgentSessionOptionLaunch and
buildNativeChatSessionOptionCommand build the composed `--model` argument from
the caller's picks and the catalog, never from a descriptor.

Both surfaces mark an unconfirmed value instead of captioning it, and the two
reasons stay distinct — `default` says the catalog value is what a launch will
send, `unreported` says nothing has told us anything. Only `unreported` is
reachable in the structured lane, where the agent may be routing a tier we have
never been told about, so the two never share a label.

* fix(native-chat): let assistive tech read the option value marker

The marker was aria-hidden next to an explicit aria-label, so the label
already won the accessible name and hiding it only cost screen reader
users the default-vs-unreported distinction that sighted users get. It is
now referenced by aria-describedby, which keeps the name Fast mode.

Mobile's summary row said "Not set" for a boolean while the sheet behind
it showed the switch on, so the two screens disagreed. A boolean always
has a value; the summary states it and the sheet's marker qualifies it.

* chore(i18n): drop the On/Off option strings the switch row retired

Replacing the On/Off radio pair removed the only call sites for these two
keys. i18next cannot rebuild a key with no call-site default, so leaving
them in the catalogs forced them into the boot bundle as dead weight.
Removing them shrinks it by two entries instead.

* feat(native-chat): describe slash commands from the provider's own report

The Claude session reports a description and argument hint for every
command it can run, but the catalog kept only the name, so the `/` picker
described the handful of commands our curated map covers and left the rest
— `/goal` included — with a blank row.

Carry `description`/`argumentHint` through the catalog and the session wire
(both optional, so mixed-version hosts are unaffected), and let a reported
description win over the curated one, which stays as the fallback for the
name-only report shape. The curated maps are untouched, so structured
dispatch still claims exactly the commands it claimed before.

* feat(native-chat): show the reported argument hint in the slash picker

`argumentHint` was carried to the renderer but nothing read it. Show it
beside the command token — `/goal <objective>` over the description — so a
row says how the command is invoked, not just what it does.

It sits at the row's existing 11px muted tier, subordinate to the
description, and truncates in a min-width-0 flex row; the picker also caps
the hint at 80 characters, so a provider cannot swamp the row.

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

f2af92b2fa feat(native-chat): show live background work and name each row by kind (#19705)
* fix(codex): reserve the label's share of a qualified command row

A child's label is raw provider text and was spliced into the command
row unbounded, then the pair clipped to the description cap. A label at
or past that cap clipped the command away entirely, leaving a row of
kind 'command' that named an agent and showed no command - the failure
qualification exists to remove, inverted. The same clip could also cut a
surrogate pair, which boundSubagentField already guards against on the
agent row two lines away.

Give the label a reserved share and clip it the way the agent row does.

* feat(native-chat): show live background work and name each row by kind

The strip suppressed itself in three places: the Claude tracker blanked
its roster for the whole of any turn, the Codex tracker returned nothing
while a primary turn was open, and the renderer view gated on
`turnId === null`. Between them, work in flight was never shown — and a
task backgrounded in an earlier turn vanished from the strip as soon as
the next prompt was sent. Claude additionally dropped every foreground
subagent, so a fan-out reported nothing at all.

Report work while it is live, in all three layers. Foreground Claude
work is turn-scoped, so `result` retires it — that is the provider's own
outcome for a task it marked foreground, not a roster sweep. Nothing
settles a Codex child on turn end: those keep reporting well past their
parent, so turn frames only prompt a republish.

Name each ROW by kind — Subagent, Shell command, Workflow, Monitor —
instead of a generic "Background <kind>", each drawing the glyph the
shared tool-icon table already uses for that category. A row that
carries a provider description still shows it unchanged. The collapsed
header summary is deliberately untouched; it is owned elsewhere.

The conversation-command gate is unchanged in effect: an open turn
already refuses first, and Claude foreground work never reaches the
backgrounded set the gate reads.

* fix(native-chat): withhold the row stop Claude foreground work cannot honour

The strip now publishes foreground rows, but `stoppableTaskIds` still filters
on `backgrounded`, so `stopClaudeBackgroundTasks` resolved an empty target list
and returned `{ cancelled: false }` that no renderer reads: the user clicked
"Stop Subagent" and nothing ever happened.

Carry stoppability per row instead of widening the stop to a target the SDK has
no way to reach. `AgentSessionBackgroundTask.stoppable` is absent-means-yes, so
hosts that predate it keep their working control, Claude emits `false` only on
foreground rows, and the strip hides that row's button the same way it already
hides the stop-all a provider cannot honour.

* fix(claude): scope aggregate-roster authority to the work it enumerates

`background_tasks_changed` lists BACKGROUNDED tasks, so a foreground subagent
can never appear in it. Treating it as the whole world meant any such frame
cleared every live foreground row mid-flight and then dropped every later
foreground `task_started` for the rest of the session, killing the in-turn
fan-out the strip exists to show in any session that ever backgrounds anything.

Decide `backgrounded` before the staleness guard and apply the guard only to a
backgrounded start, and retain live foreground entries across a roster replace.
Retained rows count against MAX_TRACKED_TASKS, so the map stays bounded, and a
stale backgrounded start the roster no longer lists is still dropped.

* test(native-chat): pin the strip's monitor amber to the constant that defines it

`MONITOR_GLYPH_COLOR`'s comment claimed a test held it and AgentStateDot's amber
together, but no test imported it — the assertions hardcoded 'text-yellow-500',
so the two could drift with every test still green. Read the colour from the
module, which is what the comment always said was happening. Drop the unused
`BackgroundTaskGlyph` export too: nothing outside the module names it.

* fix(native-chat): keep the task list open across a gap in live work

The strip is now mounted on live work, so a sequential fan-out unmounts it
between one subagent finishing and the next starting: local `useState` meant
the expanded list collapsed itself on every such gap, on top of the strip
flickering above the composer.

Hand the disclosure to the session, keyed by session id so it does not leak
across a session switch. The strip is now controlled and holds no state of its
own, which is what makes it survive its own mount churn.

* fix(codex): route every command-row cut through one surrogate-safe clip

`boundLabel` avoided splitting a pair, then `qualifiedDescription` re-cut the
COMPOSED string with a raw slice: label (<=96) plus separator plus description
(<=512) is up to 611 chars, so that second cut landed at an arbitrary index
inside the description and could publish a lone high surrogate — lossy through
any non-JSON UTF-8 hop. `parse` had the identical hazard on an unqualified
primary-thread command.

One `boundText` helper now owns all three cuts, so no path in the file can emit
a lone surrogate from well-formed input.

* fix(claude): keep terminal evidence for ids an aggregate roster never lists

Narrowing the admission guard to backgrounded starts left a finished FOREGROUND
id with no defence: `replaceAggregateRoster` wiped `terminalTaskIds` wholesale,
so after any `background_tasks_changed` a replayed `task_started` revived a task
whose completion had already been seen — and only a later `result` could settle
it again.

Scope the wipe the same way the guard was scoped: delete only the ids the
incoming roster actually enumerates. A roster still overrules terminal evidence
for the work it lists, which is what that behaviour was added for.

* fix(claude): keep retained rows in place and evict the stalest, not the newest

Re-adding retained foreground entries after the roster made a live row the user
is reading jump below the backgrounded rows on every `background_tasks_changed`,
and the cap `break` kept the STALEST retained rows while dropping the newest.

Merge in the tracked map's own order so a surviving row holds its position, and
count the overflow up front so eviction takes the oldest retained rows. Roster
entries are never starved and the map stays bounded either way.

* fix(claude): retire leftover foreground rows when the next turn starts

A foreground `task_started` arriving with no turn open has no `result` coming
to retire it, so it sat in the strip indefinitely — with no per-row stop, since
foreground rows are not stoppable — and refused conversation commands behind an
instruction nobody could follow.

Settle on turn start as well as on `result`. This is cleanup only: visibility
never consults `startsTurn`, so a missed one degrades to today's behaviour and
can never switch the feature off. It shortens the row's life to the next turn;
the case where no further turn is ever sent is filed separately.

* fix(agent-session): withhold unstoppable rows from readers that predate them

Rule 3 of remote-wire-compatibility: changing what the host publishes reaches
old clients with no wire change. The Claude host published no foreground rows
before this feature; it does now, and a client that cannot read `stoppable`
draws a per-row Stop on every one of them — Claude always sets
`supportsTaskStop` — which filters to the backgrounded ids, stops nothing, and
returns a result no renderer inspects. That is the dead button `stoppable` was
added to remove, reappearing across a version skew.

Negotiate it. A client can advertise the existing background-task-stop
capability and still predate `stoppable`, so this needs its own constant.
Readers that do not advertise it get unstoppable rows dropped, and a state whose
every row is dropped becomes no strip — exactly their pre-feature view.

RUNTIME_PROTOCOL_VERSION is not bumped: this adds an optional field and a new
negotiated capability, and changes no existing field's meaning, which is the
explicit do-not-bump case in protocol-version.ts.

* test(agent-session): name the projected rows so the fixture typechecks

An indexed lookup into the fixture's task list is possibly-undefined under
`pnpm tc`; the rows are more readable named anyway.

* test(web): advertise the row-stop capability in the e2ee auth expectation

The web e2ee handshake started sending
AGENT_SESSION_BACKGROUND_TASK_ROW_STOP_CAPABILITY, and this test asserts the
advertised list by deep equality, so it went red on CI while every targeted
test run stayed green. Add the capability in the position the router sends it.

* test(claude): pin why the roster empties mid-turn in a sequential fan-out

The strip unmounting between two sequential subagents is truthful, not a swept
row: A leaves on the provider's own terminal frame, B does not exist yet, and
backgrounded work spanning the same gap holds the roster open — so an empty
roster is never work the strip is hiding.

Also pins the previous-turn rule against the one the subagent roster already
applies on the same frame: a still-working FOREGROUND child becomes
`unverifiable` there and a backgrounded one is left alone, so the strip drops
the first and keeps the second rather than asserting `live` for either.

Brennan BensonandMerge Sim 2bf298d1dc feat(native-chat): the background-tasks strip says what is running (#19311)
* feat(native-chat): name, group, and state the background-tasks strip

The strip above the composer described five different kinds of background
work as "Monitoring background tasks", with identical flat-dot rows. Now:

- Wire: additive optional `name`, `state`, `startedAt` on
  AgentSessionBackgroundTask, plus `settledTasks` on the state object so
  terminal siblings of a live fan-out stay visible without changing what
  old clients render (they keep exactly the live `tasks` list).
- Reducer equality learns the new fields, so a publish whose only change
  is a task's state is no longer judged equal and dropped.
- Header counts by kind and lists states within a kind; past three kind
  segments (or on a narrow strip, measured by its own border-box against
  the live root font size) it falls back to an honest total, never a
  partial enumeration, and the strip stays expandable whenever the header
  is lossy.
- Rows group by kind (Agents / Shell / Monitors / Workflows / Tasks),
  stable-sorted first-seen-then-id, each with a kind icon, its own state
  dot, a resolved name (description -> name -> kind label), and elapsed.
- Claude producer: task frames now carry name (agent_type/subagent_type),
  a run state mapped from patch status, and first-seen startedAt. Terminal
  statuses settle a task (completed->done, failed->blocked,
  killed/stopped->idle) instead of deleting it; settled tasks render only
  beside still-live work and flush when the last live task ends, so the
  strip exits exactly when it does today. An unreadable patch leaves a
  task open, never settled.
- Turn gating moves off the strip: the tracker no longer zeroes its
  roster during a foreground turn, and the client renders the strip
  whenever it has contents while the idle-only flag now gates just the
  animated monitoring indicator and conversation commands.

* feat(sidebar): indent native-chat subagents under their session row

buildSubagentChildRows() has always rendered indented children from
parentEntry.subagents, and the structured-session status bridge has
always published an AgentStatusEntry for native chat — it just never
populated subagents. Connect them:

- Wire: additive optional `backgroundTasks` on AgentSessionStatusSummary
  (live tasks only), projected by the host status feed from the
  provider's backgroundTaskState hook and republished on task edges via
  the background-task channel, with the shared task equality suppressing
  no-op re-projections.
- Bridge: maps agent-kind tasks onto the sidebar's own
  AgentSubagentState (working/waiting/blocked, terminal -> idle) — kinds
  stay distinct, so a backgrounded shell never lands in a subagent
  count — and extends its pre-write equality with the existing
  agentSubagentsEqual.
- parentIsFresh for a bridge entry means "the host feed reported a
  change inside the sidebar's ordinary evidence window": every publish
  restamps evidenceObservedAt, and a dead feed stops restamping, so
  children decay to idle on lost contact instead of pinning 'working'.

* fix(native-chat): settle tasks the aggregate roster evicted first; carry usage

Real-agent QA showed settledTasks never rendered. A frame capture from the
SDK (probe against claude 2.1.261) explains it: when a backgrounded child
finishes, the producer emits `background_tasks_changed` FIRST — with the
task already absent — and only then `task_updated`/`task_notification`
with the outcome, in the same tick. The tracker's settle path looked the
task up in the live roster the aggregate had just evicted, so retention
lost the race 100% of the time.

Fix: aggregate eviction of a live backgrounded task now parks its details
in a bounded recently-removed map (new claude-settled-background-tasks.ts,
which also owns the settled roster), and the trailing terminal edge
consumes it. A removal whose outcome frame never arrives still vanishes —
nothing is guessed into a finished state. A second terminal edge for the
same task re-derives the settled state and can add final usage. The
captured sequence is replayed verbatim as a tracker test, including the
kill-at-exit tail proving the strip still exits with the last live task.

The same capture disproved the PR's earlier claim that Claude task frames
carry no usage: task_progress and task_notification both carry
usage.total_tokens. Additive optional `totalTokens` on the wire task,
covered by the shared equality; the tracker takes usage (never the
transient "Running <tool>" description) from task_progress, and rows
render the mock's "18.1k · 2m" meta — settled rows keep final usage with
no still-growing clock.

* chore(i18n): sync runtime-required catalog for backgroundTasks.runningList

* fix(native-chat): preserve background task lifecycle and bound update work

* fix(native-chat): transfer resumed background tasks to one live owner

* fix(native-chat): bring structured session host under the line cap and restore subscribe fixture

* fix(native-chat): complete journal stubs and stop notifying on feed teardown

The status feed's projection cache calls journal.cursor(); the rename test's
stubs are cast through unknown, so the missing method only surfaced at runtime.

Teardown runs only once nothing is activated, so there is no mounted reader to
notify - clearing confirmed sessions is what prevents a stale live on reactivation.

* feat(native-chat): lead each strip header count with its kind icon

The header carried one aggregate state dot, so a fan-out of agents and a
monitor looked alike. Each count segment now leads with its own kind glyph;
a collapsed total spans kinds and takes none.

Monitor is the heartbeat AgentStateDot already draws for monitoring, so the
strip and the agent sidebar speak one vocabulary.

* feat(native-chat): give the strip's monitor heartbeat the sidebar amber

The glyph matched AgentStateDot but the colour did not, so a monitor in the
strip did not read as the monitor in the agent sidebar. One shared tone helper
now serves the header segment and the expanded row, so they cannot diverge.

Monitoring is a state the app already colours; the other four kinds are plain
markers and stay neutral. A running turn still dims the whole set.

* fix(native-chat): draw the strip header separator in a visible tone

The separator used `text-border`, a divider-line token that is 7% white in
dark mode - an order of magnitude fainter than the counts on either side, so
the dot between them read as absent. main.css already records that token as
too faint for a visible mark.

* fix(native-chat): give the worktree-ps journal stub a cursor

The status feed's projection cache calls journal.cursor(); this stub is cast
through unknown, so the missing method only surfaced at runtime. Its journal
never changes, so a real one would hold the cursor steady.

* refactor(native-chat): split the sidebar subagent rows out of this PR

The strip stands alone: the sidebar mapping, its observation plumbing and the
AgentStatusEntry.subagents wiring move to a stacked follow-up. No wire field
here is sidebar-only - the strip's rows read name, state, elapsed and tokens.

* perf(native-chat): keep task usage out of the session status summary

A `task_progress` frame ticks a background task's `totalTokens`, which
failed the status feed's equality check and re-broadcast a full summary to
every `agentSession.subscribeStatus` subscriber — paired-web and SSH/relay
clients included — for a number no session list renders. The projection now
drops usage; tokens keep flowing on the background-task channel the strip
reads.

* fix(native-chat): correct token unit rounding and drop the unused dot state

`formatBackgroundTaskTokens` rounded before choosing the unit, so 999_950
rendered as "1000k" instead of "1m"; pick the unit from the rounded value.

`backgroundTasksDotState` has no caller on this branch or the stacked
sidebar PR, and its multi-kind branch would report 'monitoring' over an
attention state. Delete it rather than leave it to be wired up.

* fix(i18n): drop the orphaned backgroundTasks.runningList key

The strip rewrite removed its only call site, and an unreferenced key gets
promoted into the eagerly parsed boot catalog. Delete it from en.json and
regenerate en-runtime-required.json.

* fix(native-chat): show the reason on every attention row

The row guarded the reason line on 'waiting', so an 'unverifiable' child
("no contact") and a 'blocked' one ("failed") rendered bare while the
collapsed header named exactly those reasons. `backgroundTaskStateReason`
already returns null for the non-attention states, so the guard was only
lossy — the SSH boundary requires the unverifiable verdict stay legible.

Also keys the header segments off their kind discriminant instead of the
translated display text.

* fix(native-chat): make the strip header agree with its own count

The headline counts live AND settled rows, but the state breakdown omitted
'done', so one working agent beside four settled ones read "5 agents — 1
working": the count said five, the breakdown accounted for one. Done now
appears in the muted detail (never as an emphasised segment) so the two
agree.

The single-command header also drew an elapsed clock on a settled task,
which the row already refuses as a lie about finished work.

* perf(native-chat): memoize the background-task roster grouping

The 1 Hz elapsed tick re-rendered the strip, and the render body regrouped,
re-sorted and re-translated every task each time only `now` had changed.
The header still derives from `now` on purpose.

* test(native-chat): cover settled rows and the mid-turn mounted strip

Neither headline behaviour had component coverage: every strip render passed
`settledTasks={[]}`, and the `showBackgroundTasks` seam was never set true,
so the strip staying mounted through a running turn was exercised nowhere.

Adds a settled-beside-live row test (final usage kept, no clock, no stop) and
a mid-turn mount test (strip present, turn owns the voice). The background-task
tests share one session-element helper so the file stays under its line cap.

* refactor(claude): keep MAX_TASK_ID_LENGTH module-private

Nothing outside claude-background-task-frames.ts references it; the export
was residue from this PR's split.

* test(native-chat): give the mid-turn strip test a real turn

main now gates the composer's stop button on a provider-minted turnId rather
than the send-time working signal, so a test claiming a running turn has to
supply one. The controller mock hardcoded turnId null.

Brennan BensonandMerge Sim 5868fdc9e3 feat(native-chat): report Codex background tasks in the chat strip (#19346)
* feat(native-chat): report Codex background tasks in the chat strip

The background-tasks strip works for Claude only; a structured Codex
session shows nothing in it. Feed it from the Codex app-server stream.

The strip stands for work that OUTLIVED a turn, which is what the
monitoring header, Claude's foreground suppression, and the conversation
command gate all already assume. Codex has no `is_backgrounded` flag, so
that fact is derived from the turn boundary: a `subAgentActivity` child or
a primary-thread `commandExecution` becomes visible once the turn it
belongs to completes and it is still unsettled.

`turn/completed` only reveals a task here, never settles one — measured on
`codex app-server` 0.153.4, a spawn_agent child reported `completed` 95.8s
after its parent turn ended. Only a child's own activity kind settles it.

Codex exposes no honest stop: `turn/interrupt` on a child ends its turn
without emitting a terminal activity item and leaves its shell running. So
the state carries a new optional `supportsStopAll: false`, the strip hides
a control that could not act, and the blocked-command message asks the user
to wait rather than to press a button that does not exist.

* refactor(codex): move session teardown out of the structured adapter

Merging main crossed the 300-line cap on
`codex-structured-session-adapter.ts`: the rewind backend (#19235) and this
branch's close-time strip clear both landed in it. The four close paths move
verbatim into `codex-structured-session-teardown.ts`, where they funnel
through one `settled` helper instead of repeating the notification-retry and
background-task cleanup at each call site. No ratchet bump.

Also normalize a background task's description once at receipt rather than on
every projection; the roster is re-projected on each observed frame.

* fix(codex): drop the shell row the journal already settles

A `commandExecution` still `inProgress` when its turn ends was reported as a
`command` task. But `settleCodexJournalTurn` writes exactly those items to the
journal as `state: 'failed'` on `turn/completed` and forgets them, so the strip
row would have claimed a shell was still running at the same instant Orca
recorded that it was not — two surfaces contradicting each other about the same
process.

A subagent is the opposite case and stays: the roster pointedly does not sweep
at a turn boundary, because children measurably outlive it. That leaves the
producer making exactly one claim — these spawn_agent children are still live
after their turn — which the durable roster row corroborates.

* fix(native-chat): track Codex background execution lifetimes

* fix(native-chat): keep running tool groups from claiming completion

* Fix runtime catalog and capability expectation

* fix(codex): keep a child's name on the command row that outlives it

A child agent's commands stay hidden behind its agent row while the child
works. Once the child's turn settles with a command still running, that
command surfaces as its own row labelled from the raw command string, so
'long_probe' became "/bin/zsh -lc 'ping -c 300 127.0.0.1 > /dev/null'"
at the moment that row was the only remaining signal for the work.

Qualify a child's command row with the child's label. Resolved on read,
so a label registered after the command still lands, and bounded by the
existing description cap so admission accounting stays valid. Primary-
thread commands are left unqualified: they have no child to name.

Brennan BensonandMerge Sim 1c1cb7115a fix(orchestration): unify structured-session status across worktree ps and sidebar (#19217)
* fix(orchestration): stop worktree ps reporting a busy structured session as idle

A worktree running a structured Claude or Codex chat read as idle to `orca
worktree ps`, while the desktop sidebar showed the same session working. The
sidebar was right: the host already projects a status summary for every
structured session and publishes it, and the renderer maps it into an agent
row. `worktree ps` simply never consumed it, so the agent-facing surface was
the blind one.

Structured sessions have no PTY, so they reach neither the hook snapshots nor
the retained ones that every other row is built from. This reads the summaries
the host has already published and applies the same projection the sidebar
does — working, attention as blocked, otherwise done — so the CLI and the GUI
cannot disagree about one session.

Two things worth knowing:

The connected-PTY evidence gate had to be skipped for these rows. It exists to
drop a row whose PTY is gone, which is the wrong question for a session that
never had one; a structured row's liveness evidence is the status feed that
produced it. The exemption is keyed on the row being structured, so every
PTY-backed row keeps today's behaviour.

`RuntimeWorktreeAgentRow` needed no change. It was already a non-PTY shape —
paneKey, state, agentType, and no ptyId, connected or writable — so a
structured row fits without inventing a fake terminal coordinate.

The pane key is the DERIVED one the renderer already publishes, never the
orchestration bearer handle or the minted worker pane key: both are
credentials, since `orchestration check` is identity-gated and accepts a
caller-supplied pane key.

`orca terminal list` is deliberately untouched, and a test pins that. Adding
rows there breaks real consumers: mobile mounts a terminal WebView per row that
can never receive a frame, a `connected`-keyed refresh check goes permanently
true and pins shipped clients to a fast cadence with no exit, and the plugin
projection has no field that can carry `writable: false`. Every safe consumer
of a terminal summary checks `ptyId`; the breaking ones key off `connected` or
mere row presence, which no added field can qualify. An honest partial-listing
count there is a separate change.

* fix(runtime): report only live structured sessions in worktree ps

The status feed's `published` map is a broadcast cache, not a roster. It
deliberately never retracts — an evicted idle session is still idle, and a
reloading renderer must not lose every settled row — so enumerating it lists
every session the host has ever opened, and eviction's `forget-session` step
deletes the session from the live map while touching nothing else.

Reading it as a roster made `worktree ps` report a closed chat forever. The
sharp edge is a chat closed while an approval was pending: a deliberate close
does not settle a pending prompt, so the retained summary stays `attention`,
maps to a `blocked` row, and merges the worktree to `permission` for the whole
30-minute freshness window — on the CLI and on the mobile sidebar it backs.

The poller now answers from the sessions the host still holds, intersecting the
live map with the retained projections. `subscribe()` and its snapshot are
untouched: retention there is the point. Gating on the live session set rather
than the visible tabs keeps a headless orchestration worker listed, which is
what the agent-facing surface is for.

Also folds out two things the enumerator left behind: the working/attention/idle
to working/blocked/done mapping now lives once in the shared projection module
instead of once per process, which is what actually enforces "the CLI and the
GUI cannot disagree"; and the structured row source no longer builds a
write-only `payload` behind an `as` cast that compensated for nothing. The
structured source construction moves to its own module to keep
runtime-worktree-agent-rows.ts clear of the 300-line cap.

* test(runtime): execute the structured-host call site in worktree ps

Both structured-row suites called attachRuntimeWorktreeAgentRows directly
with summaries they built themselves, so nothing ever ran getWorktreePs's
own `getStructuredAgentSessionHost()?.liveSessionStatusSummaries()`. That
file carries `@ts-nocheck`, so renaming the accessor was green in typecheck
and in the suite, while `orca worktree ps` and mobile's 3s poll would throw
a TypeError for every user — the `?.` optional-chains the host, not the
method. Swapping the call back to a whole-cache read was equally invisible:
the liveness suite injects feed.liveSessionSummaries() itself, and the
string-match guard only needs the identifier to appear somewhere in the file.

Drives the real runtime with a stub host over a real status feed that has
published two sessions and forgotten one, asserting the live session's row
reaches ps output, that the live accessor is the one called, and that the
`?? []` fallback still returns a page with no host installed. The stub is
typed against the real host, so a class-side rename reddens tc here.

* refactor(runtime): admit agent sources before worktree row projection

* fix(runtime): preserve host-authoritative structured status

* Fix structured host session activity lifecycle

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

* fix: seed Claude slash catalog before the first prompt

* test: verify unclassified catalogs survive session publication

* feat(chat): show turn-scoped activity tail

* fix(chat): keep turn activity broad

* feat(chat): surface provider activity in turn tail

* fix(chat): keep reasoning headline as activity and widen redaction

A Codex reasoning summary streams as a bold headline followed by body text.
Folding the whole summary into the tail leaked literal ** markers and body
prose; only the first non-empty line is activity copy, and an unterminated
bold header mid-stream is unwrapped too.

Redaction used a hyphen for GitHub token prefixes (they use an underscore),
and missed fine-grained GitHub tokens, AWS access key ids, JWTs, URL
userinfo passwords, and bare token= values.

* fix(chat): wait for a complete reasoning headline

A bold headline still streaming has no closing marker yet; holding the
previous activity copy until it lands avoids flashing a half word.

* refactor(chat): drop bespoke secret redaction from activity copy

Reference agent hosts render provider-derived status text unredacted;
this table was the only one of its kind and its GitHub pattern matched
no real token. Bounding and the reasoning-headline extraction stay.

Brennan BensonandMerge Sim c7bcfa750a fix: restore the full sidebar agent row for structured native chat (#19137)
* fix: restore the full sidebar agent row for structured native chat

The host status feed projected only state, prompt, and agent type, so a
structured Claude/Codex row fell back to the tab title and the agent-type
label where a hook-reported row shows the running tool, the agent's last
message, and the model.

Project the tool line and the newest assistant prose from the journal, and
take the model from the session record's acknowledged options. The tool scan
stops at the live turn's lifecycle row and only runs while a turn is running,
so an abandoned call from a crashed turn is never reported as live work. The
assistant line is bounded to the shared preview cap rather than the hook
field's 8 KB body: a streamed reply re-projects on every journal checkpoint,
and the row renders one line of it.

6494f2a4f0 fix(native-chat): resume a structured chat from Agent Session History (#18933)
* fix(native-chat): resume a structured chat from Agent Session History

Clicking Resume on a chat-UI row could only reveal an already-open tab. If the
chat had been closed, or this process had never published it, the click re-read
an inventory that did not contain it and toasted "Retry in a moment" — advice
that could never come true, because nothing republishes an unpublished tab. The
legacy `claude --resume` fallback is deliberately refused for structured-owned
rows, so the row had no way back at all.

`close` already keeps the record and the journal on disk so a session can be
attached again, and the hold path already resurrects one in full. What was
missing was the tab: `restoreReadableSessions` is latched to run once, at
startup, so nothing could ask for a single session later.

Adds `agentSession.reveal`. The host looks up its own record, restores the
session readable, and republishes the tab through the same call
`agentSession.create` uses. Deliberately narrow:

- It takes no hold. A provider child exists because a surface asked, and the
  chat pane asks when it binds.
- A journal it cannot read is not a refusal. A chat whose journal predates the
  SQLite store restores to nothing here, but attach still recovers it, so the
  tab is published and the pane's hold finishes the job.
- Workspace and provider come from the record, never the client, so a session
  id alone cannot aim the publication at another workspace.

Claude and Codex both, by construction: eligibility is `adapterSupportsRecord`,
which the router answers from the record's own provider.

Gated on a new advertised capability rather than probing for method_not_found,
matching agent-session.structured.hold.v1 — absence is visible during
negotiation instead of by calling.

* fix(native-chat): negotiate reveal against the host that owns the workspace

The capability gate read the LOCAL runtime's advertised capabilities while the
call went to the host that owns the workspace, which for a paired workspace is
a different build. On desktop the renderer and its local host are always the
same build, so the gate passed unconditionally and proved nothing about the
host being called: an older paired host still received the unknown method and
its method_not_found was reported to the user as 'this chat is no longer on
this host'. The cache it read also starts empty and resets to empty when
status.get fails, so 'not fetched yet' and 'unsupported' were the same value.

Gate on the environment that will answer, the way agentSession.close already
does, and skip the round trip entirely for a local host. Reveal now reports
four outcomes instead of a boolean, so a host that is merely too old is not
reported as a chat that is gone, and a host we could not reach keeps the
retryable message.

Also syncs the localization catalog: the 'gone' key shipped without an en.json
entry, which reddens static analysis and verify while typecheck stays green.

* fix(native-chat): tell a refused reveal apart from a missing chat

The host raises two refusals here and they mean opposite things to a user: it
holds no such record, or it holds one no adapter of its own can open. The
client collapsed both into 'this chat is no longer on this host', which is a
eulogy for a chat still sitting on disk. Read the refusal code, and fold the
host-side case in with the too-old host under one honest message, since the
remedy for both is the same.

Adds the coverage the readiness pass found missing: the host's reveal answer
itself (workspace and provider from the record, both refusals, an unreadable
journal, a live session), and the activation branches for a host that cannot
open the chat and for one that never answered.

* fix(native-chat): read a host version block as the host's age, not a lost link

The capability probe reaches assertRuntimeStatusCompatible, which throws a
runtime_compat_block error. Treating that as unreachable told a user with an
out-of-date host to retry, which is the one thing that cannot help. Branch on
isRuntimeCompatBlockError the way remote-agent-session-launch already does for
the same probe.

Also adds the refusal-code case a previous commit claimed and did not deliver:
nothing drove a structured_agent_session_unsupported reply through the reveal
client, which is the branch that commit existed to add. Corrects a doc comment
that reveal made wrong: attach is no longer the only call that builds the host.

* fix(native-chat): let a dragged history row reach the same reveal as a click

Dropping an Agent Session History row onto a pane activated the tab by id and,
on a miss, raised the very toast this PR exists to remove — so the same row
answered a click and a drop differently, and the drop kept the advice that can
never come true. The structured branch never used the drop pane, so routing it
through the shared activation loses nothing and gains the reveal.

The helper only ever read one field, so its parameter narrows to that field and
the drag payload satisfies it directly. A source ratchet holds both entry points
to the reveal-capable path, since a mounted drag harness does not exist for this
layer and what regresses is a call site, not a rendering.

* fix(native-chat): stop an advisory refresh ending the click, and one click per row

Manual QA found the reveal never ran: the inventory refresh that precedes it
is an optimization, but its failure returned early with 'not available yet,
retry in a moment' — reinstating the dead end this PR removes, one step
earlier. A failed refresh now falls through to the reveal, which is the repair
and does not need the refresh to have worked.

The click can chain a refresh, a capability probe, a reveal and a second
refresh, each with its own timeout, while nothing on the row says it is
working. A per-session in-flight guard keeps an impatient second click from
running the whole sequence again and landing its own toast.

Also drops an unreachable owner scope: the snapshot apply discards any
worktree whose execution host is not local before it reads one, so naming a
remote scope there described a synchronisation that cannot happen.

* fix(native-chat): bound the capability probe and stop naming the wrong machine

The in-flight guard releases when the activation settles, so an await that
never settles holds the row for the life of the process. The capability probe
was the one call in the chain not raced against a deadline: on a cache hit it
awaits a promise an earlier probe created, which may carry no deadline of its
own. Race it like the two calls around it.

A version block can name either side — evaluateRuntimeCompat reports
client-too-old as well as host-too-old — so a message that blamed the host
pointed half of those at the wrong machine. Name the remedy instead of the
machine, which is true for every case that reaches it.

* chore: remove a scratch repro file committed by mistake

It was swept into the previous commit by a broad `git add` while a diagnostic
ran in this worktree. It asserts the current renderer-sync defect as expected
behaviour, so it would fail the moment that defect is fixed.

* fix(native-chat): stop a reveal's own inventory refresh discarding its republished tab

Manual QA: the host answered reveal with ok:true and republished the tab, and
the chat still did not reopen — only a renderer reload brought it back.

The renderer publishes under one epoch string for its whole lifetime, and a
frame recorded under a different lineage retires that epoch permanently with
nothing to un-retire it. The Resume click asks for an inventory first, and a
worktree the host holds no entry for answers with the none/v0 sentinel; the
structured path recorded it, retiring the renderer's own epoch, so the tab the
reveal published a moment later was dropped. A reload minted a new epoch,
which is why reloading appeared to fix it.

A frame that carries no publication is not a later publication to fence
against. Treat the sentinel and a removal frame as a cursor reset, the way the
mainstream session-tabs path already clears its tracking — its comment names
this exact hazard: recording that sentinel would retire the host epoch and
reject the next live frame.

Pre-existing, and it swallows an ordinary new-tab launch on an empty worktree
too; the reveal is what turned a silent invisibility into a visible failure.

* fix(native-chat): let a retraction prune its rows without retiring the epoch

Correcting the previous commit. Skipping a retraction frame outright stopped it
pruning the mirrored rows, so a worktree the host no longer publishes would
have kept a chat on screen with nothing behind it. Apply the frame as before
and clear its cursors instead of recording them, which is what the mainstream
session-tabs path does.

The unpublished sentinel keeps its cursor now too: it is skipped rather than
cleared, so a stale frame arriving late is still fenced. Adds the case the
earlier version would have broken.

* fix(native-chat): keep the retraction's fences, and fence the reveal's refresh

Correcting the retraction handling again. Clearing its cursors was more than the
bug needed and cost a guard: the host mints a fresh epoch when it rebuilds a
pruned entry, so a republication is never gated by the retained cursor, while
dropping it left an inventory response issued before the close free to land
afterwards and strand a chat row for a worktree the host no longer publishes.
Skip only the recording. The mainstream path keeps its epoch history for the
same reason, as a tombstone fence.

The test that justified the stronger clearing asserted a host behaviour that
does not exist — a rebuilt entry republishing under the renderer's epoch with a
restarted counter. It now uses what publishStructuredAgentSessionTab actually
mints for a pruned entry, and a new case covers the frame that would strand.

Also fences the reveal's inventory refresh on the sync generation, which every
other caller that applies an inventory already does: structured chat can be
switched off mid-flight, and the answer would otherwise re-seed a row into a
renderer that just discarded them.

* fix(native-chat): drop the retraction's epoch history, keep its version cursor

Third and final shape for this branch, and the only one of the three that holds.

Keeping both maps re-poisons the epoch one cycle later: the consumer here is
also the publisher, so the history's current is the renderer's own lifetime
epoch, and recording the reveal's fresh epoch retires it. The next chat the
renderer publishes is then dropped — this bug again, one close later. Deleting
both loses the guard that stops a frame issued before the close landing after
it and stranding a row nothing republishes.

So: clear the history, keep the cursor. The mainstream path keeps its history
as a tombstone because there the epochs belong to a remote publisher; that
reasoning does not carry to a path that publishes under its own.

Each of the three variants now fails a different test.

* fix(native-chat): a retraction forgets what is current, not the tombstones

The delete lost a fence the cursor cannot replace: the version cursor only
compares within a lineage, so a delayed frame from an already-superseded epoch
had nothing left to stop it putting a chat row back for a worktree the host no
longer publishes. Keeping the record intact had the opposite fault — the
renderer's own epoch is the history's current, so the next frame under any
other epoch retired it.

Clearing only current does neither: noteRetiredValue retires nothing when there
is nothing current, and the tombstones stay. Each of the four shapes now fails
a different test.

* fix(native-chat): narrow the retraction frame through its own type

Typecheck caught what the tests could not: `removed` is not on
RuntimeMobileSessionTabsResult. The repo already names the shape —
RuntimeMobileSessionTabsRemovedResult — so this reads it through a guard rather
than the inline cast the mainstream path uses.

Brennan BensonandMerge Sim 2513e21390 fix(native-chat): publish structured session status from the host so the sidebar never goes stale (#18776)
* fix(native-chat): publish structured session status from the host

The sidebar learned whether a structured chat was mid-turn by replaying
the session journal in the renderer, through a reader whose lifetime was
tied to the chat pane. Hiding the pane stopped the reader before the
turn's settlement arrived, so the row stayed on "working" until the chat
was reopened. The same coupling meant a tab never opened this session
showed no status at all, and a reloaded renderer lost every settled row.

The host owns the journal, so it now projects each session's status once
per journal publication and fans the changes out on one stream per client
(`agentSession.subscribeStatus`). The projection survives eviction of an
idle session's provider child and is republished when readable sessions
are restored. The renderer bridge subscribes to that feed per runtime
target and never opens a transcript reader; the observation hook is gone.

Additive wire surface behind the existing structured capability; old
hosts reject the method and the renderer retries, showing no status.

* fix(native-chat): negotiate the status feed and stop losing a change on subscribe

The status stream is additive to a surface that already shipped, so a host
advertising agent-session.structured.v1 can still answer subscribeStatus with
method_not_found. Every renderer error path reconnected, so a remote host one
release behind got a relay round-trip every 5s and no sidebar status at all.
Give the method its own capability and probe it before subscribing; a failed
probe still retries, an absent capability does not.

Re-projecting on subscribe also wrote straight into the shared cache, so a
second client could pin the first to a stale summary. Route those diffs
through publish() before the arriving subscriber is registered.

* fix(native-chat): bound the status prompt, merge snapshots, and prove the unread path

One status frame carries every retained session and a send admits 256 KB per
prompt, so ~16 large-prompt sessions could push the snapshot past the 4 MB
outbound guard and into the retry loop. Bound latestPrompt to the same
200-char single-line preview every other agent-status row already carries.

A snapshot also replaced the cached map wholesale, so the empty first frame
from a restarting host retracted every row before restore republished them.
Merge instead; the tab map, not this feed, decides which sessions are listed.

Tests: the hidden-pane claim now sits at the host, where a journal with no
transcript subscriber is driven from running to idle; the RPC test reads a
real projection instead of its own stub.

* fix(native-chat): merge the duplicated status-event type import

* test(native-chat): pin the restart status publication, and log the unsupported host

Startup restore indexes a readable session and publishes its status, which is
what puts a never-reopened tab back in the sidebar. Only an Electron screenshot
covered that wiring; a sitting status subscriber now pins it directly.

The terminal "host too old" branch was silent, so a mixed-version report showed
an empty sidebar with nothing in the log to explain it.

* fix(claude): resolve Claude structured launch args, auth, and win32 proof

The origin/main merge re-expressed the lane's Claude wiring onto main's split
orca-runtime facade and dropped three wires past green typecheck and lint.

- resolveLaunchArgs discarded its provider parameter, so structured Claude
  sessions were launched with Codex app-server flags; Claude exits on
  --dangerously-bypass-approvals-and-sandbox, and a Codex arg-parse throw
  could block Claude session creation outright.
- resolveClaudeLaunchEnv was no longer supplied, so the launch resolver fell
  back to the whole process env as configuredEnv and
  buildClaudeChildProcessEnv re-applied every auth var it had just stripped.
  The resolver now merges the Claude overlay onto a strip-applied copy of the
  inherited env, which also keeps PATH intact for withCliRuntimeOnPath.
- The windowsProcessStartTimeAvailable producer was gone while the contract
  field and both consumers survived, so the renderer gate fail-closed and
  structured native chat was unreachable on every win32 host.

Separately, structured Claude pinned CLAUDE_CONFIG_DIR unconditionally. An
explicit pin makes the CLI abandon the macOS Keychain even when it names the
CLI's own default, so a default claude.ai account could not authenticate where
the legacy Claude terminal could. Pin only a home the CLI would not resolve on
its own, matching ClaudeRuntimePathResolver, and compare against the env the
child would otherwise inherit so a diverging overlay cannot outrank the
record's account home.

Also await the now-async revealNativeSession in its regression test, and set
the native status before revealing so a rejecting reveal cannot leave a
session released but never marked native.

A store write failure while recording a handoff outcome escaped the flow

agent_session_store_corrupt error in the proven-dead-retry suite, whose
teardown raced the flow's trailing outcome write). Record the failed

The structuredSessionCloseFailed toast fires for any structured session,

reachable behind the agent === 'codex' gate, so its copy stays as is.

Its scope line also said Windows keeps using terminal chat, while the gate

PR 1 of the SDK migration: dependency + test-only harness, no product wiring.

- Pin @anthropic-ai/claude-agent-sdk to exactly 0.3.251 — not the newest
  release — because 0.3.251 (published 2026-08-28) clears the repo's 3-day
  minimumReleaseAge supply-chain gate with no exclusion, while the newest
  release was minutes old and would have required excluding a brand-new
  publish from the exact control built to catch brand-new malicious
  publishes. Every contract this design depends on was verified identical
  on 0.3.251: the full option surface, no pid on SpawnedProcess (custom
  spawner stays mandatory), env defaulting to process.env when omitted, and
  --replay-user-messages appearing only via extraArgs.
- Exclude all eight bundled CLI platform binaries via
  ignoredOptionalDependencies. The setting lives in pnpm-workspace.yaml
  because pnpm 12 no longer reads the package.json "pnpm" field (it warns

* feat(claude): drive the structured transport through the agent SDK

Replaces the hand-rolled `claude -p --input-format stream-json` transport with
@anthropic-ai/claude-agent-sdk 0.3.251, keeping the existing connection
interface for this commit so the acquisition path changes minimally. The
control-plane rewrite is a separate change.

Orca still supplies the process. `spawnClaudeCodeProcess` routes through
`spawnProcess`, retains the child and its pid — the triple the durable lease
adjudicates on — drains stderr so exit errors keep their tail, and hands `.cmd`
shims to Orca's Windows argument encoder rather than the SDK's plain spawn.
`close()` keeps Orca's own bounded tree-kill and exit deadline, so it still
resolves true only after an observed exit.

Launch resolution emits an SDK options object instead of argv; durable
`launchArgs` translate to a typed option where one exists and to `extraArgs`
otherwise, refusing a token neither can carry rather than dropping it. The
child env is always passed explicitly — omitting it would let the SDK inherit
`process.env` and reintroduce the ambient `ANTHROPIC_*` leak. The stdout line
parser is deleted; the SDK owns framing, and unknown frames still reach the
translator verbatim.

* fix(claude): settle the frame the SDK pulled but never wrote

The SDK's input pump is `for await (frame of prompt) { await transport.write(frame) }`.
When that write rejects — the child dies between Orca's liveness guard and the
write — the for-await ends abruptly and calls the generator's `return()`, so the
code after `yield` never runs. The frame was already shift()ed out of `queued`,
so the later `fail()` from the exit path could not reach it and `send()` never
settled: `dispatchClaudeTurn` awaits that send before it can return `unknown`,
wedging the caller and the durable outbox. The pre-SDK transport rejected on the
stdin write callback instead.

Retain the in-flight entry and settle it from the generator's cleanup, and let
fail() reach it too for the pump that never resumes at all.

* fix(claude): keep the agent SDK behind the structured-Claude boundary

The ordinary OrcaRuntimeService graph statically reaches the Claude adapter and
so the transport module, whose first line imported @anthropic-ai/claude-agent-sdk.
The SDK is evaluated whenever the regular runtime loads, before any structured
Claude session is chosen: it sets process.env.NoDefaultCurrentDirectoryInExePath,
changing Windows executable resolution for later subprocesses, and a missing or
incompatible install would break normal runtime startup — for a user who never
leaves the terminal/TUI path.

Defer the SDK to the connection, memoized so it loads once per process, and add
the import-graph ratchet: a walk from the Electron main entry that fails on any
static import of the package, plus a clean-fork check that loading the runtime
leaves the Windows search variable untouched and a child-process pin that the
side effect is still real.

* fix(claude): answer list_models so the picker stops serving the seed

sendControlRequest had no list_models case, so every request hit the default
reject; readClaudeStructuredSessionOptions swallows that with .catch(() => null)
and falls back to the static catalog. Every structured session therefore served a
hardcoded model list with no per-model effort levels, no resolvedModel and no
default detection, and nothing surfaced the failure. The pre-SDK transport got the
live catalog from the CLI.

Route it through the SDK's supportedModels(), wrapped in the { models } envelope
the existing parser reads.

* fix(claude): reap the child's descendants before killing it

The forced step of the exit ladder went through the Codex helper, which spawns
`pkill -KILL -P <pid>` and SIGKILLs the parent in the same tick: the parent
usually dies first, the descendants reparent to pid 1, and `-P` matches nothing.
An MCP or launcher descendant of a stubborn Claude child was left running. The
test named for that requirement declined to assert it and killed the survivor by
hand instead, so it could not fail for the thing it was named after.

Route the Claude reap through Orca's existing sweep, which snapshots descendants
while their parent link still exists and signals them before the root goes, and
on Windows uses the identity-gated `taskkill /T /F`. The test now asserts the
descendant is dead; the manual kill stays only as a failure-safe. close() still
returns true only on an observed exit.

* fix(native-chat): merge the duplicated handoff type import

CI's static-analysis lint (`oxlint --config

same module.

* fix(claude): answer a permission callback whose signal already aborted

settleFrom registered the abort listener and then delivered the request. A
callback that arrives already aborted never fires that event, so the promise
stayed pending behind a durable prompt with no cancel path. Check the signal
first, emit the cancel, and resolve the SDK's null sentinel without registering.

Claude-Session: https://claude.ai/code/session_01AobxxokqQ3qcxS7sy7ckum

* test(claude): wait for the child to record the frame, not just for its report

The scripted CLI writes its report at startup, so `until(readReport)` returned a
report with no user messages whenever the child had not yet read the line. The
assertion then failed under parallel load. Poll for the frame instead of for the
file.

Claude-Session: https://claude.ai/code/session_01AobxxokqQ3qcxS7sy7ckum

* fix(claude): coalesce partial deltas onto one assistant item and stop painting result frames

Under --include-partial-messages every stream_event frame carries its own
uuid, and the final assistant frame for a block carries yet another; only
message.id ties them. The translator keyed each delta by its frame uuid, so a
reply painted as one bubble per delta chunk followed by a complete duplicate
under the final frame's uuid. The block's first stream frame now mints the
claude:(sessionId, uuid) identity, deltas coalesce onto it through the shared
60ms seam, and the final frame reconciles onto that same item.

Known SDK bookkeeping no longer reaches the provider-fallback row: result
subtypes are catalogued and settled by the turn lifecycle, an empty thinking
block (redacted thinking) is a modeled kind, a string-content user replay is a
text block, and an empty user frame paints nothing. An unmodeled result
subtype or content kind still lands on the bounded fallback row.

Claude-Session: https://claude.ai/code/session_01GaP5HpYQbvy2hYehVhwfEW

* fix(claude): prove descendant exit at the close boundary instead of on an unref'd timer

close() reported proven=true as soon as the direct child exited while the
descendant sweep's SIGKILL sat on an unref'd 2 s timer, so a SIGTERM-resistant
MCP server outlived the lease release. The reaper now composes the same shared
primitives the Codex structured provider uses: snapshot, verified bounded
descendant termination on POSIX, taskkill /T /F on Windows. The proof is false
whenever descendants outlive the deadline, a retried close re-verifies the
retained snapshot rather than trusting the dead root, and the raw pipe child no
longer goes through the PTY job sweep it never owned a job for.

Measured on macOS: a killed child of a SIGSTOPped parent stays a matching zombie
row in ps, so the root is killed while verification runs rather than stopped
first as the Codex non-group path does.

Claude-Session: https://claude.ai/code/session_0161QFm3KVRNJKfdzWVGVNWk

* feat(claude): replace the hand-rolled control plane with the SDK's native surface

PR 3 of the Claude structured SDK migration removes the wire-frame scaffolding
PR 2 kept, so Orca drives the SDK's typed control surface directly.

Inbound permissions move from a rebuilt control_request dispatch to the SDK's
canUseTool / onUserDialog callbacks. The prompt registry now carries the
callback's own resolver: a decodable can_use_tool becomes a durable prompt whose
answer settles the callback; a malformed one is denied without registering; the
SDK's abort signal (fired on control_cancel_request, which the SDK matches and
dedups itself) forgets the prompt and settles it null, and a late answer after
abort finds no prompt and is refused. Closing settles every in-flight callback so
no promise dangles. The claude-agent-sdk-control-bridge that rebuilt the wire
frame is deleted.

Outbound control maps to Query methods: interrupt() for cancel, setModel /
setPermissionMode / applyFlagSettings for options, supportedModels for the model
list, initializationResult() for init proof, each under Orca's own request
deadline and error classification. Cancel is interrupt-receipt aware: a CLI
advertising interrupt_cancel_queued_v1 gets cancel_queued in one round trip,
otherwise the receipt's still_queued uuids are swept with cancel_async_message so
a cancelled turn cannot spawn a later unexpected turn; older CLIs resolve no
receipt. Init keeps the 10s deadline and the unauthenticated-startup guidance.

Every behavior is failing-first and ablation-proven; the toggle-off import
boundary and the accepted loss of unknown-control visibility rows are unchanged.

Claude-Session: https://claude.ai/code/session_01Pqjduxt5G4rr9aYvtp7rNm

* fix(claude): arm the descendant snapshot before stdin closes and make the tree verdict unproven by default

A healthy Claude root leaves within the graceful window, and the close ladder
only snapshotted descendants when the root was still alive after that window.
So the common close never looked at the tree: `treeExited` stayed null,
`!== false` passed it, and close() reported a proven exit with an MCP child
still running. A root that died before the walk made the snapshot vacuous too.

The proof is now unproven by default. The reaper holds one verdict in Orca's
vocabulary (exited / live / unverifiable), assigned in exactly one place from
the bounded verification, and close() returns true only on `exited`. The
snapshot is armed before stdin closes, while the root can still be walked, and
is verified after the root exits; a root that left before any snapshot could
be armed stays unverifiable rather than vouching for descendants it never
showed us. The shared verifier gains the three-way verdict behind its boolean
face, and the connection reports the root and tree verdicts separately along
with the child's exit status.

One verification per close attempt: the retried close re-verifies, so the
intra-attempt re-reap is gone from the teardown budget.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): verify the Windows tree after taskkill instead of trusting that it ran

`terminateWindowsProcessTree` resolves from taskkill's callback whatever the
error says, so a timeout, an access denial, a recycled root and a surviving
descendant all looked identical to the reaper — which then returned a proven
exit unconditionally. close() reported true and the lease was released with an
MCP descendant potentially still live.

The Windows branch now snapshots the root's descendants while it is alive and,
after taskkill, polls a fresh process table to a bounded deadline: a row still
matching by pid AND creation time is `live`, an unreadable table is
`unverifiable`, and only a table with no match is `exited`. Creation time is
the PID-reuse guard the POSIX path gets from ps lstart, so a descendant that
denied a creation-time query is omitted rather than signalled on a bare pid.
A root already observed exited is never taskkilled: `/T /F` on a recycled pid
would take an unrelated tree down with it.

The captured tree is tagged by platform so neither verifier can be handed the
other's rows.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): release a reservation on a first-hand root exit instead of latching it into manual recovery

Making close() strict about the descendant tree exposed a second defect at the
same boundary. A create-time acquisition has no ownerProcess until publication,
so an unproven cleanup mapped to handoffStage `manual-recovery`, and
adjudication then refuses every later attach with agent_session_ownership_unknown.
A user who was merely signed out, or whose --resume the CLI rejected, wedged the
session id permanently.

Each question now answers from its own evidence. close() is unchanged and stays
strict about the tree. Separately, the lease is keyed on the root's pid and
start time, so when Orca's own child handle observed that root exit and no
descendant snapshot was ever admissible, the reservation is released and the
CLI's exit code and stderr reach the user. A descendant observed still alive,
or a root Orca never saw leave, stays unproven and keeps the reservation.

The settlement records only what was observed: the released lease says the
provider process exited and its descendants were not verifiable, rather than
reusing the wording that claims cleanup proved no child remains.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): surface an API error a result frame reports instead of settling the turn on it

The SDK models an API failure as a SUCCESS-subtype result whose `result` string
is the user-facing error text, with no assistant frame behind it. The translator
suppressed every catalogued result subtype as turn bookkeeping, so that turn
tombstoned its lifecycle and showed the user a completed, empty reply with no
sign anything had failed.

Suppression is now by meaning. A result reporting a failure routes to the
bounded provider-error surface, leading with the provider's own sentence and
keeping the raw frame behind the row's disclosure; ordinary successful results
stay off the timeline as before. A turn the user aborted also stays suppressed:
its interrupt frame already says so, and its execution diagnostic would only be
noise on every stop.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): drop the stream state of turns that never received their final frame

Every streamed delta recorded its block's identity, latest text and checkpoint
length. Only the final assistant frame removed them, so an interrupted turn left
its whole accumulated reply reachable until the session was disposed, and a long
session with repeated interruptions grew those maps without bound. The partial
text was already journaled by the flush that precedes settlement, so the live
copy was pure retention.

That state now lives in its own module, named for what it does — grow a streamed
block's journal row between its deltas and its final frame — and turn settlement
drops every block still awaiting a final. The translator reports how many remain,
which is the invariant: a settled turn leaves none.

Also makes a timed-out process-table read retryable while the root is still
alive. A loaded host can miss the table's one-second deadline, and latching that
as "no descendants" both lost the descendant sweep and, on a busy machine, made
the close ladder report unproven for a tree it never actually looked at. Only
the root's death still makes a missing snapshot final.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* perf(claude): capture the Windows descendant tree from one process-table read

The capture walked the descendant tree and then read the table again for the
creation times the walk's projection drops. Each read is bounded in seconds and
both run inside the close ladder's budget, so the second one cost the worst-case
teardown three seconds for data the first read already held.

The walk is now exported from the module that owns it and runs over rows the
caller has already read, which is also what lets the snapshot keep the
PID-reuse guard the projection cannot carry.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(pty): spend the descendant verification window instead of surrendering on one slow table read

The verification abandoned the whole check the first time a process-table read
missed its own one-second deadline, with seconds of its window still unspent.
On a loaded host that reported a tree unverifiable without ever having looked at
it, which the Claude close ladder then turned into an unproven close and a
retried teardown. It also made the descendant-exit tests flake under a parallel
suite run, for the same reason and with the same honest-but-premature verdict.

A read that missed its deadline is now simply not an answer: the loop waits and
reads again until its own deadline, and only a window that ends without a
readable table reports unverifiable. This can only turn a premature verdict into
one backed by evidence; it never manufactures a proof.

Claude-Session: https://claude.ai/code/session_01BSmXgkWSsNHft8jFkdBFG9

* fix(claude): never let a later failed look collapse an observed live descendant into unverifiable

The reaper's single assignment site latched only 'exited', so a second reap
whose table reads all missed their deadline overwrote an earlier completed
verification's 'live' with 'unverifiable'. The acquisition release gate
discriminates on exactly that pair, so a root exit after such a decay released
the lease over a descendant that had been observed alive. The latch is now
monotone in trust order: exited is final, and live is only ever raised to exited.

Claude-Session: https://claude.ai/code/session_01HfdhsvSJucLw4cTZxzg2CP

* fix(claude): never prove a Windows tree gone while a descendant denied identification

The Windows snapshot dropped rows that denied the creation-time query, and an
emptied snapshot was judged exited without any table read: a descendant Orca was
refused information about was treated as one that had left. The snapshot now
counts the unidentified rows it saw, and verification caps its verdict at
unverifiable while any exist. Nothing is ever signalled on a bare pid, as before.

Claude-Session: https://claude.ai/code/session_01HfdhsvSJucLw4cTZxzg2CP

* fix(claude): classify cleanup after a first-hand exit as a root exit instead of a proven tree

When the CLI died between a successful acquire and the host's commit or proof
of the lease, handleExit had already removed the session, so releaseAcquisition
found nothing and reported true. The attach flow then settled exit-proven with
deathEvidence claiming cleanup proved no provider child remains, though the
tree was never verified. The adapter now keeps the exit that removed a
published session until the session is acquired again; acquisition cleanup runs
that connection's close ladder and classifies its verdict exactly as a
start-time failure would be, so the record reads root-exit-observed. The wire
helper keeps that typed classification and its provider diagnostic instead of
wrapping it as unproven, and the router gives up its owner even when the
release throws.

The direct root kill goes through the handle Node owns, not through a pid:
libuv drops that handle in the same turn it reaps, so the signal either
reaches the process Orca spawned or reaches nothing at all. Gating it on a
process-table probe therefore bought no safety and cost the tree its only
fallback whenever the probe declined -- a first capture landing in the fork's
own second, a recycled descendant pid voiding the snapshot, or a process table
that could not be read on either platform.

Identity verification stays where a bare pid is genuinely addressed: Windows
`taskkill /T /F`, and the descendant sweep's own revalidation before it signals.

Also stops a declined root probe from collapsing an observed `live` or `exited`
descendant verdict into `unverifiable`, and stops a successful taskkill from
reporting `unverifiable` because a later probe found the root correctly dead.

* docs(claude): rewrap the root-kill ordering comment

* Match the Claude structured launch to the terminal path's managed-account auth rules

The SDK path stripped ambient Anthropic auth unconditionally, let an explicit
agentDefaultEnv override beat a pinned managed account, and had no account-switch
guard. Reuse the terminal preflight's own predicate and messages so both transports
strip, refuse, and report identically, and cover the CLI transcript location that
mobile native chat depends on.

* Reach the Claude structured chat lane from the desktop UI

The main process has had a complete, correctly gated Claude Agent SDK lane for
a while, but no renderer ever asked for it: the launch route accepted only
`codex`, and the create path was typed `agent: 'codex'` end to end.

Widen both to the structured provider union that already exists
(`AgentSessionHandleProvider`), and generalize the codex-named create path
instead of adding a Claude twin beside it. The pending-launch registry is now
keyed by agent as well as workspace — a shared key handed a second caller the
first agent's intent, so a Claude and a Codex launch in one worktree collided.

Windows, per agent. Codex's client-side win32 refusal is deliberate and settled
elsewhere, so it stays exactly as it was. Claude's answer is no longer guessed
from the client's platform: a structured session fences its provider child on
that child's process start time, and only the executing host knows whether it
can read one. `agentSession.createSupport` already answers precisely that, per
agent, and had no renderer caller — so the Claude create path asks it before
creating and turns a "no", or a probe it cannot get answered, into the
definitive refusal the launch fallback already handles. Fail closed either way.

That refusal mapping also closes a real gap: the host reports an unsupported
location by throwing `structured_agent_session_unsupported`, which reaches the
client as a transport rejection rather than a refusal envelope, so
`StructuredAgentSessionCreateRefusalError` never fired. The launch would retry
the create, strand itself in `visibilityUnknown`, run no legacy fallback, and
show an error toast.

Close a fail-open hole while Claude and win32 become reachable: `create` with a
client-supplied location, and `ensure`, both skip the worktree-resolving support
check. They now ask the executing host the same question directly, so a host
that cannot fence a provider child no longer creates one on a client's say-so.

Also deletes `structured-agent-session-provider-routing.ts`, a duplicate of
`structured-agent-session-provider-support.ts` with no importers.

WSL, SSH and paired hosts, floating workspaces, draft prompt delivery, explicit
TUI customization and initial session options all keep refusing; folder
workspaces keep working.

* P1-1: make the structured Claude auth policy required and testable

The optional dep plus a {stripAuthEnv:false} fallback meant a dropped wiring
under-stripped silently. Required at all three hops, asserted at install time for
the @ts-nocheck caller, and the settings-to-policy mapping is now a named tested
function.

* P2-3: mobile's default Claude transcript root must follow CLAUDE_CONFIG_DIR

session-file-resolver's default ignored the variable the pinned account home
follows, so a CLAUDE_CONFIG_DIR launch wrote one tree and mobile read another. The
Task-4 test now resolves with no root override (mobile's own call) and checks the
answer against the root the CLI itself reports, instead of mirroring the code under
test's own expression.

* P2-1/P2-2/P3: close the teardown window, join the live-auth gate, align the refusal

P2-1: a switch beginning inside the acquire teardown left a dead chat and no
replacement. Past that point the launch waits the swap out and refuses only if it
never settles; the entry guard still refuses outright, because nothing is torn down
there yet.
P2-2: structured children now hold the same OAuth-refresh gate a Claude PTY does,
so a managed refresh cannot rotate the token out from under a live turn.
P3: the refusal now matches the strip it guards (case-folded on win32, presence not
truthiness), and the dead structured-to-TUI builder states its auth policy instead
of silently signing a system-auth user out.

* Make the live-auth gate tests independent of sibling connection teardown order

* Do not offer structured Claude under a WSL-only managed account

Structured Claude launches against the ambient Claude config, which the account
service keeps in sync with the selected HOST account. A WSL-bound managed
account lives inside the distro and is never synced there, so on Windows a
structured session would authenticate as whatever the ambient identity happens
to be while the UI names the WSL account — the user is told one identity and
given another.

That was unreachable only because nothing offered structured Claude on win32.
Enabling it makes it reachable, so gate it here rather than patching the auth
layer: refuse the structured path when the active managed Claude account is
WSL-bound, and let the terminal-backed path — which resolves the account per
runtime — handle that account shape.

The answer rides the agentSession.createSupport seam the renderer already
consumes, so no new capability and no renderer knowledge of account internals.
A create the host declines becomes the definitive refusal the launch fallback
already turns into a legacy native chat tab, with no error toast.

Unknown answers refuse. An install with no managed accounts claims no identity
and is fine, but an active selection that cannot be resolved — or account state
that cannot be read at all — is not evidence that the ambient identity is right.

Claude only. Codex resolves its account through a different path and its
createSupport answer is untouched, as is every Codex routing decision.

* Read the structured Claude account gate through the auth policy's accessor

The gate resolved the active account from the account-service snapshot's
runtime map; the auth policy resolves it with
getSelectedClaudeAccountIdForTarget(settings, { runtime: 'host' }). Those are
two sources and two resolution rules, and they disagree on a legacy settings
blob that carries the selection only in the flat activeClaudeManagedAccountId:
the accessor falls through to it, a direct read of the runtime map does not. The
gate would then refuse a launch the policy would have run under host-1 — and in
the mirror case a session could be admitted under a policy computed from a
different account than the gate approved.

Read the same settings through the same accessor so agreement is structural
rather than coincidental, and drop the controller accessor that existed only to
reach the snapshot.

No behaviour change for any state both already agreed on; Codex is untouched.

* Round-3 review fixes: N-1 empty-value regression, N-2 gate leak window, N-4 lost history

N-1: my presence-based conflict predicate refused a terminal launch that works
today. 'ANTHROPIC_API_KEY=' is how a user blanks a variable and the settings
pipeline preserves that empty value; an empty override cannot beat the pinned
account and the strip removes the name anyway. Back to truthiness for the value,
keeping the win32 case folding.
N-2: enter the live-auth gate only after the exit/close handlers that release it,
so no throw in between can leave an entry nothing reconciles.
N-4: the Claude transcript resolver searches config-dir-then-default and de-dupes,
matching the Codex sibling in the same file, so adopting CLAUDE_CONFIG_DIR no
longer hides history written before it.

* Run the managed-account gate on every Claude acquisition, not just create

createSupport gates the create path, but a session's account state can change
while it lives. A reacquire after an unexpected child exit re-resolves the
launch and re-derives auth, with nothing re-checking the gate — so a session
created while supported could come back up in the refused shape. With the strip
predicate keyed on there being an active non-WSL account, the WSL-only user's
normalized steady state (accounts exist, none active) does not strip, and that
reacquire reaches the child with ambient auth while the UI names the account.

Gate at resolveLaunch, the one choke point every acquisition passes through,
refusing with the pre-spawn error the caller already handles. Same predicate as
create-time, now sharing one settings reader so the two cannot drift.

Claude only; Codex resolves its account on a different path and is untouched.

The runtime class that wires this does not typecheck its own `this` calls — a
missing hookup compiles clean — so the wiring is pinned behaviourally rather
than trusted to the compiler.

* Move the structured Claude gate out of the @ts-nocheck runtime files

Both call sites of the managed-account gate sat in files whose first line is
`// @ts-nocheck`, so neither was typechecked: three arguments to a one-argument
function plus an undeclared identifier compiled clean. New auth-identity
decision logic had no compiler behind it.

Move the verdict into a checked module that takes the two facts the runtime
owns — the adapter's answer and a settings getter — and decides. The runtime
class now only forwards. Move the gate reader's construction into the checked
installer too, so the nocheck file passes a plain settings closure and never
names a gate symbol.

Every reference to the gate predicate and its reader now lives in a checked
file, so the ablation that used to pass silently is a compile error at both the
create-support and reacquire sites.

Removing the file-level @ts-nocheck is a separate, larger job and is not
attempted here.

* Derive the gate test's auth policy from the settings under test

A hardcoded stripAuthEnv asserts a gate/policy pairing production cannot
produce, and false additionally lets launch.env inherit the runner's real
process.env. Derive via claudeStructuredAuthPolicyForSettings instead: the
gate settings type is the same Pick the policy takes, and both resolve the
account through getSelectedClaudeAccountIdForTarget.

* Pin the absent-vs-empty distinction in the managed-account gate

An empty claudeManagedAccounts array is a real answer: the user has no managed
accounts, nothing claims an identity, and the ambient path is legitimate. A
readable settings object with no such field is settings we failed to parse —
the same unknown as unreadable — so it refuses.

The two are one character apart in the code and the difference is invisible
without the reasoning, so record it at the branch and pin both sides. The test
fails under the obvious "consistency fix" of treating a missing field as empty.

* fix(claude): keep command queue bookkeeping out of the transcript

Claude Code 2.1.258 emits a `command_lifecycle` frame for every uuid-stamped
command it starts, completes or cancels. The frame carries a command uuid and a
state and no content, and the CLI keeps it out of its own transcript -- but it
is absent from the SDK's SDKMessage union and so from Orca's frame catalogue,
where an uncatalogued kind defaults to a substantive row. Every structured turn
therefore painted raw JSON rows into the user-visible transcript.

Catalogue it and disposition it as status chrome. The unknown-kind default stays
`timeline-substantive`: a kind we have never seen is likelier to carry content
than to be chrome, and a visible row we can catalogue later beats content we
silently dropped. A lifecycle state that reads as a failure still surfaces,
because the payload error check in `classifyProviderFrame` outranks the
catalogue.

* fix(claude): let a re-walked descendant become eligible for the forced sweep

A descendant first observed by a capture inside its own birth second could never
be SIGKILLed: `ps lstart` is second-resolution, so that capture cannot rule out
a pid recycled later in the same second, and the merge pinned each retained row
to the boundary of the walk that first saw it. SIGTERM-resistant children forked
in that window were signalled and then never escalated -- they survived close,
quit and restart, reparented to init, and had to be killed by hand.

Advancing that boundary on any later capture would be unsound: a later capture
matching pid, pgid and start-second is exactly what an impostor would also show.
But a capture is not a match -- it is a fresh ppid walk from a root Node pins
through its own handle, so a row it re-derives is proved ours at that instant
without appealing to its start time. Chain the fence from there instead, and
take that walk at the close boundary while the root certainly still lives: the
root may leave inside the grace window, and the post-timeout refresh never runs.

A row absent from the later walk still keeps its earlier boundary, and a row no
walk has ever re-derived in a later second is still never escalated.

* Treat an absent managed-account list as empty, not as unreadable

An empty claudeManagedAccounts array and a missing one are the same answer:
this user has no managed Claude accounts, so nothing claims an identity and
ambient auth is the truth. Refusing on absence strands any profile that simply
never wrote the key, and it disagrees with the auth policy, whose own predicate
takes `(accounts ?? [])` for exactly this reason.

Only settings that cannot be READ stay unknown, and those still refuse — as do
a WSL-bound active account and a selection naming an account the list does not
explain.

The earlier reasoning treated a missing field as settings we failed to parse.
That conflated "not present" with "not readable"; only the second is unknown.

* Support structured Claude when accounts are registered but none is selected

Registered-but-deselected Claude accounts were refused, which is behaviourally
identical to having no accounts at all: the auth policy does not strip, ambient
auth is the truth, and the UI names no host identity. A user who deselected
their accounts silently got legacy chat with nothing explaining why.

Nothing selected for the host runtime is two states the settings cannot tell
apart after the fact, because pruneInvalidClaudeRuntimeSelection empties the
host slot and persists null in the second one:

  honest deselection      -> ambient auth, UI names nothing   -> SUPPORTED
  the WSL-only steady state -> ambient auth, UI names the WSL account -> REFUSED

The presence of any WSL-bound account in the list decides. Simplifying this to
"none active -> supported" re-opens the auth-identity misrepresentation, so the
tests fail loudly on exactly that: five of them, across the unit rule and the
createSupport path.

* Stop treating an unanswerable create-support probe as a refusal

A worktree is not resolvable for a beat after createWorktree resolves, so a
probe fired immediately after creation fails the RPC with selector_not_found
instead of answering. The catch collapsed that into `supported = false`, so the
composer refused and quietly built a terminal session — the gate never said no,
it was never asked successfully. Elapsed time was the only input that decided
whether a Claude launch went structured.

"Could not answer" and "answered no" are different states and only the second
is a verdict. Retry while the host cannot yet resolve the selector, with a
bounded backoff that covers the measured window with margin, and keep refusing
on the first ask for everything else. Fail-closed is unchanged: a probe that
still cannot be answered when the budget is spent refuses.

The retry is narrowed with the shared error-code matcher, which classifies a
token that transports re-wrap into a longer message without matching prose that
merely mentions it.

Codex never probes, so this race has never been able to refuse a Codex launch —
the race itself is identical for it. Recorded at the early return, because
whoever gives Codex a probe inherits the bug.

* fix(claude): fence the forced sweep on re-derivation, not on lstart's second

A descendant forked in the same wall-clock second as every walk that sees it was
signalled with SIGTERM and then never escalated, so a SIGTERM-resistant child
survived tab close, app quit and a full relaunch. Two children of one parent
96ms apart across a second boundary took opposite paths. The leak predates this
branch: it reproduces with the change reverted.

`ps lstart` has one-second resolution, so a walk landing inside a row's birth
second can never rule out a pid recycled later in that same second. But a walk
is not a match: a ppid walk only reaches what the root actually parents, and the
root is pinned by Node's own handle, so a row the walk re-derived is ours
whatever second it was born in -- a stranger would have to have been forked into
our tree, and then it is not a stranger. Fence the escalation on that.

Rows a merge retained from an earlier walk are not re-derived and still answer
to the start-time fence, which remains correct for them.

Scoped to callers that revalidate identity before signalling, which is the
Claude close path. Codex teardown reaches this same verifier and is unchanged;
the argument holds there too, but widening it is its own deliberate change.

Also reverts two changes from the previous attempt at this leak. Advancing the
capture boundary on a later walk is inert once the sweep fences on re-derivation
-- both key on the same set of rows, so the new term short-circuits for exactly
the rows whose boundary it advanced. The extra ladder refresh was a duplicate
full process-table read: close() already awaits tree.refresh() immediately
before proveClaudeChildExit, on the only path that reaches it.

Known property: the kill lands roughly a grace window after the walk that proved
membership, so a pid recycled inside that gap could in principle be signalled.
It is bounded -- matchingSnapshotRows already requires the live row to carry the
same start-second and pgid, so an impostor must be born in the remainder of that
one second, land on that exact pid, and sit in the same process group, and it
has already received the unfenced SIGTERM from the same loop.

* Run the Claude structured integration suite as a runtime client

The suite exercises agentSession.* for Claude, not the mobile surface: nothing
in it asserts anything mobile-specific and its sibling integration suites use
'runtime'. Mobile now additionally requires the experimental structured-chat
setting, which structured-agent-session.test.ts pins in both states, so the
stale 'mobile' fixture was claiming coverage it never had.

* fix(claude): report effort from get_settings, which is the only frame that has it

The composer's Effort pill rendered blank in every structured session. This is
not a missing source: the publication reads `effortLevel` off the `system/init`
frame, and that frame has never carried an effort of any kind, while the correct
value is already fetched at acquisition and thrown away on the auth diagnostic.
Verified two ways -- a live get_settings probe against Claude Code 2.1.258, and
the shipped binary's own init frame construction, which lists `model` and no
effort. So `reportedOptions.effort` was always empty, the options reader dropped
the key, and the pill had no value. Model survived only because
`currentModelId()` has a fallback chain.

The get_settings call acquisition already makes reports the session's current
effort as `effective.effortLevel`; pass that into the publication instead.
Selecting an effort already worked, so this is the arrival value only.

The legacy PTY path is unaffected and must not be "fixed" to match: it reads its
effort by parsing the startup banner (`CLAUDE_MODEL_EFFORT` in
src/renderer/src/components/native-chat/claude-terminal-session-options.ts),
which is why it shows a value where the structured path does not.

Also removes the fixture that hid this: the fake init frame invented
`effortLevel: 'high'`, a field the CLI does not send, which is why every gate
stayed green over a value that is always empty in production. The fixture's
get_settings now returns the real {applied, effective, sources} shape instead of
a bare `{env: {}}`, so the two adapter tests that asserted an effort keep
asserting it through the path production actually uses.

The reader returns null rather than defaulting: an effort nothing measured would
repeat the fixture's mistake, and a blank pill is the honest degradation if the
provider ever renames the key.

* fix(claude): only record an effort the child confirms it adopted

apply_flag_settings answers `success` for an effort it then ignores. Measured
against Claude Code 2.1.258: applying `bogus-effort-xyz` returns
subtype "success" with no error while `applied.effort` stays at its previous
value, and a valid `low` moves it. The option write treated the absence of a
throw as adoption and recorded the requested value unconditionally, so Orca
would show and persist an effort the child was not using, with nothing anywhere
reporting a problem.

Read the effort back after applying it, through the same reader the arrival
value uses, and reject when the child reports a different one. A readback that
could not be taken is not evidence of a refusal -- the apply itself succeeded --
so it still records; only a readback that disagrees rejects.

Not reachable from today's picker, which offers catalog values only, but the
CLI's effort catalog is server-delivered and has changed before, so a retired id
would otherwise become a pill confidently displaying a setting that never took.

* test(claude): assert the effort contract against the real binary

The blank pill survived every gate because the only tests that touched it were
fixture-backed, and the fixture invented the field. A test that pins the shape
we read cannot catch the provider renaming the key, which is the failure mode
that produced this defect.

Asserts both halves against a live authenticated CLI: that no frame it publishes
carries an effort at all, and that the session's current effort arrives through
get_settings. Which frame proves the session varies by host -- this machine
proves it with a SessionStart hook rather than a system/init frame -- so the
negative half asserts over every published frame rather than picking one.

Skips with the rest of the file when no authenticated CLI is present.

* fix(claude): stop the synthesised content-part kinds leaking into the transcript

Sending an image put a bare `claude · message:user:content:image` row between
the user's bubble and the answer. Two causes, and only the second is a family.

An image part counted as modelled only when `source.type === 'url'`, but
claudeDispatchMessageContent sends a local attachment as a base64 source and the
CLI replays that shape back, so every attached image was classified unmodelled.
Accept the base64 and file sources Orca itself sends.

The family is the real defect. `message:<role>:content:<type>` kinds are
synthesised at runtime from whatever `part.type` arrives, so unlike the
top-level frame catalogue they can never be enumerated ahead of time -- the
`?? 'timeline-substantive'` default then prints the synthesised name at a user
who cannot act on it. That default is right for top-level frames, where
"substantive" means show the frame; here it meant show our own vocabulary, which
drops the content AND leaks the opcode.

So an unrenderable part now renders a sentence saying exactly that, with the
kind and payload still on the row's disclosure. A part that carries its own
readable sentence keeps it -- the placeholder is a fallback, not an override.

An unknown future part type is therefore visible, never silently dropped and
never printed as a kind: the same principle as the effort readback, which
records only what the provider confirms.

* Declare agentSession.requestHandoff on the cross-version wire surface

The manifest is a ratchet for cross-version reachability, so the method is
declared with real HandoffParams rather than counted. requestHandoff is
capability-gated through requireStructuredHost and has no client caller, so
declaring it is the whole of the change.

Also model two host capabilities the harness omitted: the stub host's
supportsCreate, and the fake adapter's, without which adapterSupportsCreate
falls through to a supportsLocation the fake also lacks. Every ensure was
refused for the harness's silence rather than for its location.

* Gate structured Claude session tabs on the client capability that names them

The Claude structured lane deleted the projection's `agent !== 'codex'`
filter and added CLAUDE_STRUCTURED_AGENT_SESSION_RUNTIME_CAPABILITY in the
same commit, but never wired the constant to anything. Paired clients then
received agent-session tabs for Claude, which no shipped client renders --
mobile's resolveMobileNativeChat returns null for every agent but codex, so
the row listed and selected into a pane with neither chat nor terminal.

Restore the filter behind the declared capability instead of the bare agent
name. No client advertises it yet, so this matches main's behaviour today
and becomes a negotiation a future client can opt into.

* Confirm the structured Claude model against the model the CLI reports

set_model answers success for any string, including a model it cannot
resolve — the failure only surfaces when the turn runs — and get_settings
reports the settings-file model, not the session's. The init frame that
opens each turn is the only channel carrying the adopted model, so keep
the session's reported model current from it instead of reading it once
at acquisition.

Also stop rejecting an effort the readback cannot represent: max is
session-scoped and excluded from the persisted effortLevel, so a readback
reporting the level underneath it is an absence of evidence, not a refusal.

* Clear the session-option hedge when the provider confirms the value

The pill claimed every option was unconfirmed for the life of the session:
the renderer recorded each write as dispatched and nothing ever moved it,
so a model the CLI had already reported back still read as unconfirmed.

Carry the provider's own confirmation to the surface. Main reports which
option ids the provider named rather than merely accepted, and the client
re-reads options as a turn changes, because the frame that opens a turn is
where the adopted model arrives. A value the provider has not reported
stays hedged, including an effort whose readback could not be taken.

The confirmed list is optional on the wire: a host that predates it sends
nothing and the client keeps hedging, which is the behaviour it had.

* Keep the model report current across an acquisition fence bump

* Show the picked session-option value and let the provider report correct it

The pill showed a "not confirmed" second tooltip line for any value we had sent
but not yet seen reported back. Nothing acts on it, and for the PTY lane it was
permanent — that transport has no report channel. The pill now shows the picked
value immediately and the provider's per-turn report corrects it when the two
disagree; a newer local write still outranks a report that precedes it.

`dispatched` stays as a provenance member rather than collapsing into `applied`:
it is produced independently by the PTY lane, and it is where the `confirmed`
wire field lands, which would otherwise be unobservable.

Effort keeps its readback and its rejection path. That matters more now, not
less: with the hedge gone the rejection is the only user-visible failure signal
on this surface, so a spurious one would be the loudest bug here. Skipping the
readback for an effort the settings response structurally cannot echo is what
prevents it — the response carries the persisted level, so reading it back for a
session-scoped value would report the level underneath and fail a valid write.

* Hedge a session-option value only when the terminal transport sent it

Both lanes emit `dispatched`, so it could never say which one produced a value.
The descriptor now carries the transport that built it, set once in the shared
snapshot builder from a parameter that is required rather than defaulted — the
builder is the only place a descriptor is constructed, so a new producer has to
name its lane or fail to compile.

The structured lane confirms every value from the provider's own per-turn report,
which makes the hedge transient noise there. The terminal lane can only learn an
outcome by parsing the screen back, and only for Claude: every other agent's
`dispatched` value stays unconfirmed for the life of the session, so the line is
the only signal that we sent something we never saw land.

* Refuse an effort the session's model advertises no control for

* Refuse tab mutations on a Claude row the client never negotiated

The branch added a case asserting a client advertising only
agent-session.structured.v1 may mutate a claude row. That is the same
ungated behaviour the projection gate removes, encoded a second time —
mutation authorization reads the projection, so hiding the row refuses
the write. Assert that contract instead, and add the positive case for a
client that does negotiate Claude rows.

* Resolve the Claude session's current model in one place so the effort guard and the pill agree

* Record an effort the child did not adopt instead of refusing the write

apply_flag_settings answers success for an effort it then ignores, so the
readback exists to detect that. Refusing on it made the detection a veto,
and a veto is only correct if the readback can never be wrong about which
model is current -- which it was, twice. The pre-flight guard already
refuses a level the model advertises no control for, so the veto guarded a
door that is now locked upstream.

Keep the detection, drop the refusal: a disagreement records the child's
own answer and omits the option from confirmed, so main stops vouching for
a value the provider rejected without blocking the user's write.

* Stop a slow whole-machine ps from being read as an absent process

`ps -axo ...command=` pays a per-pid argv read: measured 1.15s for 1,948
processes (0.03s without `command=`), and CPU contention stretched the same
capture to 6.0s. Two budgets sized for a cheap look then misreport a readable
machine.

The reader's 3s ceiling killed 6 of 20 consecutive captures at load 27, so
every consumer answered "unverifiable" about a table it could read. Raise it
to 15s, and stamp the capture instant at ps START so `capturedAgeMs` is the
upper bound its contract promises -- a 6s capture used to report itself as
freshly taken, understating staleness against a 5s kill gate. The TTL keys on
completion so a slow capture still coalesces instead of forking ps per caller.

`readStructuredTuiProcessIdentity` then spent its whole 5s wait inside one
capture and concluded "no exact child" after a single look taken before the
child existed (observed landing at ~3.5s). Absence needs a look that did not
race the spawn, so require two captures before the deadline can end the loop.

Both surfaced by the real-binary Claude TUI resume test, which failed ~1 in 5
under load; 14/14 now, 8 of those runs containing a capture the old 3s budget
would have killed.

* Let the desktop renderer negotiate Claude structured tabs

The paired-client gate hides agent-session rows an agent the client cannot
render. The desktop renderer's own IPC dispatches as clientKind 'runtime'
advertising only agent-session.structured.v1, so the gate hid Claude rows
from the surface this feature ships on. It renders them; it should say so.

* Stop a slow process table from silently blinding every freshness gate

Stamping `capturedAgeMs` at ps START made the number honest, and honest broke
both consumers that read it. `ps -axo ...command=` measured 2.5-9.0s on an idle
2,002-process laptop and 4.0-18.6s at load 46, so the age it now reports lands
past every budget: `planRelayPtySweep` refuses the stop as "too old", and the
renderer's `admitRemoteForegroundEvidence` refuses the record outright. That
second one is the expensive half and was outside the diff -- a refusal bumps
`consecutiveInspectionErrors`, the poll scheduler backs off to its 10s floor,
and agent-completion detection stops for the pane. The subsystem went blind on
exactly the loaded hosts the honest stamp was meant to serve.

The evidence-publishing read now gives up at 1,200ms instead of waiting out
`PS_TIMEOUT_MS`. It is one budget for one question: these consumers ask whether
an observation describes NOW, and past this it does not -- a late answer is
refused by the age gate anyway, having first blocked a polled path for the whole
capture, so a prompt `unverifiable` is both the truthful verdict and the cheap
one. Both relay call sites already produce it from a rejection, and an admitted
`unverifiable` costs a poll where a refusal costs the cadence. Identity proof
keeps the full 15s through `getFreshProcessTableSnapshot`, because it asks
whether a process EXISTS and must never read slow as absent. The budget bounds
the wait, never the capture: the reader coalesces, so an abandoned wait leaves
its capture running to fill the cache rather than forking a second whole-machine
`ps` on the host that can least afford one.

1,200ms is bracketed rather than picked. The floor is the capture's own cost --
`command=` measured 1.15s for 1,948 processes on an idle host, and a budget
under that answers `unverifiable` about a machine nobody is straining. The
ceiling is the consumer's: 2,000ms, less the 500ms a TTL-shared capture may
already have aged, leaves 1,500ms, and transit takes the rest.

That ceiling only fits once the capture stops being charged twice. `ps` runs
inside the RPC round trip, so its duration is already in `receiveDelay`, and
`capturedAgeMs` is that same duration on the host's clock; summing them halved
the budget this gate grants a host from ~2.0s of `ps` to ~1.0s, which is why a
1.2s capture arriving at 1.3s read as 2.5s old and was refused. Admission now
takes the larger of the two. The sweep's gate keeps its sum, which is correct
there: `evidenceAgeSinceListingMs` is stamped after the listing ARRIVES, so it
measures planning time and overlaps nothing.

A stated limit rather than an assumed one: 15s is not proven sufficient for
identity proof. The same capture reached 18.6s at load 46, so that path can
still time out and answer "no exact child" about a host it simply could not read
in time. Narrowing it needs a cheaper question than a whole-machine argv read,
not a larger number.

The one test guarding this field could not fail. `beginPtyHandlerTest` installs
fake timers, so `Date.now()` is frozen, the real reader reports exactly +0, and
`0 <= 500` held identically for a hardcoded zero, for completion-stamping and
for start-stamping -- while the real reader on that host returns thousands of
ms. It now drives a measured age in and asserts the handler publishes it rather
than restamping; that the reader MEASURES it correctly stays pinned separately,
against a controllable clock. Both consumers get boundary coverage either side,
and each new gate was ablated red before it went green.

* Keep the compatibility fields off the capture the budget just abandoned

inspectProcess falls back to processHasChildren and listProcesses to
getForegroundProcessName, and both read the same TTL-shared capture with
no budget of their own. On a slow host they joined the in-flight capture
the budgeted evidence read had just given up on, so the call still blocked
for the full 6-18s and the budget bought nothing -- once for inspectProcess
and once per managed PTY for listProcesses.

Use the degraded answers those helpers already give for an unreadable
table, reached promptly. pty.hasChildProcesses keeps its unbudgeted fresh
probe: it is a one-shot destructive gate that can afford to wait.

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 structured session journal durability

* fix structured tab active pointer after restart

* fix(native-chat): await optional lease renewal callbacks

* refactor(skills): extract install error messages

* fix(agent-session): harden recovery ownership

* fix(native-chat): retain panes across tab activation

* fix(native-chat): address round-one review findings

* test(native-chat): align integration coverage after main merge

* fix(native-chat): harden round-two reliability

* fix(native-chat): harden round-three reliability

* fix(native-chat): close round-four recovery gaps

* fix(native-chat): separate bounded journal key forms

* 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
