Brennan Benson acea59c6d8 refactor(native-chat): remove the records-file and per-chat journal imports (#26038)
* refactor(native-chat): remove the records-file and per-chat journal imports

Every native chat user is on a build that already moved chat records and
history into the app-wide database, so the one-time copies are dead code:
the agent-sessions.json import and its owed-copy flag, the per-chat
journal.db import and the write-queue hold behind it, and the pre-SQLite
log.jsonl notice.

* refactor(native-chat): remove what only the deleted imports used

- JournalHostDatabase.unsyncedTransaction and the synchronous-pragma reset
  that undid it; JOURNAL_SYNCHRONOUS is now module-local. The stranded
  rollback test drives transaction() instead.
- deleteUnpublishedJournalRows and its SQL, plus its test.
- boundJournalStatusText.
- Stale comments naming the removed first-use copy (queued messages,
  send refusal example, JOURNAL_SYNCHRONOUS doc).
- Write-queue and readInOrder comments: a write also lags when issued
  behind one still waiting in line.
- Resolved-append ordering test binds the sink from inside a running read,
  so a resolver that read at handover now fails it.

* test(native-chat): run resolved-append in the SQLite runtime project

Brennan Benson d0b0f13b74 fix(native-chat): hold a queued message until the turn ahead opens (follow-up to the Stop-event plan, fixes STA-9348) (#25217)
* test(native-chat): a Stop over a card sent now into the running turn keeps it paused

Red on main: Codex's turn end withdraws the steered hand-off and the queue
sends the card again as a new host turn, with no pause recorded.

* fix(native-chat): a Stop's queue pause holds a card whose hand-off is still unanswered

A card sent now into the running turn was still pending when Stop judged the
pause, so nothing was recorded; the interrupt then withdrew the hand-off, the
card went back to waiting unpaused, and the queue sent it again as a new turn.
The pause now counts a hand-off that may still return to waiting, judged with
the appended row applied, so a withdrawal lands under the pause and an
acceptance retires it in that same write. Codex and Claude both hit it.

* test(native-chat): the Claude re-send case fails on its diff, inside the test's budget

* test(native-chat): a pause held by an unanswered hand-off ends on every path that ends it

The provider's answer, the provider dying, the chat closing, a restart, a
withdrawal still owed at open, and a /clear (refused until the hand-off ends,
then carrying every waiting card paused 'cleared'); each ends with the queue
sending again.

* fix(native-chat): narrow the pause's settled hand-off, and assert the queued receipt's card

* refactor(native-chat): derive the queue's pause from Stop and Resume journal rows

Stop now appends one journal row where it takes effect, before the interrupt,
whatever the queue holds; Resume appends its own. The pause is a pure function
of the fold: the latest Stop with no later Resume and no later accepted turn a
person asked for. A /clear's carried cards name their source, which is the
replacement's 'cleared' pause. Host-origin turns never lift either.

One predicate decides which cards a pause holds; by default every waiting card
without a hold of its own, including one queued after the Stop. The drain's
consume re-judges it inside its own transaction.

The rows are tombstones of an id no item takes, carrying the mark: a released
host reads an unknown row kind as corruption and truncates the journal there.

Deletes the stored pause (recordPause, the retire hook on every appended row,
the settle-before-record step, mayReturnToWaiting and its row overlay) and the
tests that only proved it retires. The queued_message_pauses table stays in the
schema, unread and unwritten, for downgrade safety.

* fix(native-chat): a card queued after a Stop sends normally, never ahead of held ones

A Stop's pause now holds only the cards queued before its row, plus a steer it
withdrew, which returns to its own place. Each card records the journal
position it was queued at, and the one hold rule compares that with the Stop
row. A card queued after the Stop is a new instruction: it sends as usual, but
the drain still stops at the first held card, so it never overtakes them.
/clear's pause holds the cards it carried. Holding every card again is a
one-line switch in that rule.

* fix(native-chat): the queue's own send re-checks the no-overtake rule in its transaction

The drain's pick and its consume now read one function, nextSendableQueuedCard,
so a Stop row that lands between them holds a newer card behind an older held
one exactly as the pick would. Notes why Stop and Resume ride a tombstone row.

* fix(native-chat): stop creating the unused queue pause table

The queue's pause is derived from journal rows, so nothing reads or writes
queued_message_pauses. It was still created on every open "for downgrade
safety", but an older build creates it itself when it opens the database, so
the table only sat empty in every new database. The tests now pin that no
pause table exists.

* fix(native-chat): a Stop's pause never hides the restart pause

A Stop holds only the cards queued before it. The pause derivation still
returned the Stop alone whenever it was in force, so the restart pause was
never considered: a card queued after the Stop, written by a host process
that has since exited, sent by itself after Orca restarted, with no pause
header and no Resume. A /clear pause that held nothing could hide it the
same way.

Every pause in force is now derived. A card is held if any of them holds
it, and it names the first that does. The drain's pick, the consume
transaction's re-check and the published header all read that one rule;
the header names the pause holding the first card Resume would send.

* test(native-chat): pin the Stop's no-resend, lift and held-card rules

- The Claude and Codex Stop-withdraws-a-steer tests checked "not sent
  again" at one instant, before a queue ignoring the pause re-sends. They
  now wait for the stopped turn to end and re-check after a quiet window.
- The deleted-card test read a card queued after the Stop, which sends
  whether or not a person's turn lifts it; it now reads the Stop's pause
  before and after that turn.
- Unit cases pin that a Stop holds a card with no recorded position and one
  queued before a rewind.

* refactor(native-chat): a Stop writes one Stop event with its reason, turn and caller

The Stop row that paused the queue becomes the general Stop event
{ reason, turnId?, at, caller? }, whose reason is the host's existing stop
cause. It still rides a tombstone of a host-only id (a released host deletes
the journal from the first unknown row kind), and Resume keeps its own marker
on its own id. Only a person's Stop (reason user-stop) pauses the queue.

* test(native-chat): a rewind keeps a lifted /clear pause lifted and restates the same Stop event

* test(native-chat): pin that Stop and Resume rows never reach apps or count as history

* test(native-chat): only a person's Stop event pauses the queue

* test(native-chat): pin that a Stop's event precedes the interrupt and the at-start stop

Through the real host: the event names the turn and who asked and is in the
journal when the interrupt reaches the agent; at an agent still starting it is
there before the start is ended and holds a card queued before it; an idle Stop
writes one only when it withdrew a send; and the queue's claim re-judges a
pause that landed after its pick.

* test(native-chat): a card held at a starting agent is checked before the Stop's timing

Also says precisely what the claim's in-transaction pause check defends
against: the Stop and the drain share one serialized lane.

* test(native-chat): a released build keeps and folds a journal holding Stop events

Replays this build's rows from the released build's own journal database: every
row is kept, the history after the Stop still folds, and an older client is sent
only removed ids no item uses.

* style(native-chat): format the Stop event changes

* test(native-chat): type the released build's exports through one checked helper

* fix(native-chat): the Stop/Resume row guard narrows to those tombstones only

* test(native-chat): run the Stop-event downgrade test in CI, and cover a writable downgrade

The Stop-event downgrade test ran in no CI lane: unit shards exclude the
cross-version folder, and the cross-version lane runs a fixed file list that
did not name it. It is now on that list.

Its only case replayed the rows into a release's own fresh database, because
that release cannot open the current host database. A second case opens the
journal this build wrote with a main build that shares the database: it opens
writable, keeps every row, appends, and this build then reopens it with the
person's Stop still pausing the queue.

* fix(native-chat): a Stop that stops nothing new writes no Stop event

A Stop reaching a running agent wrote a Stop event on every press. Two
presses before the first interrupt landed wrote two events, so a card
queued between them counted as before the latest Stop and was held,
though a card queued after a Stop should send normally. A Stop naming a
turn that had already ended, as a phone sends late, also wrote an event
for a turn it never stopped.

It now writes one only when it withdrew a queued send, or stops something
no event records yet: not a turn the journal no longer runs, and not the
live turn a Stop still in force already names, unless a card was handed
over into it since, which this Stop's interrupt sends back and must hold.
The interrupt and the "already finished" note are unchanged. A Stop at a
starting agent still always writes.

* test(native-chat): pin that a later host, eviction or close Stop never lifts a person's Stop

* chore(native-chat): put each Stop-row doc on its own declaration, and say only user-stop is journaled

* fix(native-chat): any later Stop event ends a person's Stop pause

A person's Stop paused the queue until their next accepted turn or Resume,
and a later Stop of another reason (the host stopping the agent, an
eviction, a close) was ignored. Now the pause is the latest Stop event's:
a later Stop of any reason ends a person's pause, and only a person's Stop
pauses. The fold keeps the latest Stop event whatever its reason.

An eviction of a resting chat writes no Stop event (a Stop that stops
nothing writes nothing), so it cannot release held cards; a test pins that
no event means no lift.

* fix(native-chat): a second Stop press is a repeat even when the first came before the turn showed

A Stop pressed before the agent's turn shows in the journal (before
Claude's echo, or before Codex opens the turn) records no turn. A second
press once the turn showed compared that missing turn with the live one,
wrote a second Stop event, and held a card queued between the presses.

A repeat is now judged by what was sent since the Stop in force: with
nothing sent after it (a refused send aside), a Stop that named no turn,
or named the live one, is repeated and writes nothing. Anything sent since
and not refused, including a send whose fate is unknown, makes the new
press write, since its interrupt may send that card back to waiting.

Tests: the two-press case across the turn showing; a steer between the
presses settled unknown; and a Stop naming a turn that ended while the next
card is sent but shows no turn yet, which writes and holds that card. The
fold test that claimed an eviction path is renamed.

* fix(native-chat): the queue's pause ignores a Stop or Resume row holding a value no build writes

A Stop or Resume row's value is read from disk with no shape check, and
the pause fold stored whatever it found. A stored `stopEvent: null` would
then throw on every pause check for that chat: the queue's pick, its
send, and every queue update to clients. No build writes such a row, so
this is hardening.

The fold now reads a Stop only when it is an object with a string reason
and a finite time, and a Resume only when it is `true`. Anything else is
ignored: it pauses nothing and ends nothing. The row is still not treated
as malformed, which could cut the history short.

* fix(native-chat): a Stop still reads as yours after Orca restarts before the turn ends

Every stop that ends work now writes the Stop's event before it ends the child: a
person's close of the chat, an eviction (worktree teardown, orchestration stop, tab
cleanup) and the idle sweep's stop of a start that never landed. A stop that ends
nothing writes nothing, and quit writes none: its resume marker records why.

The turn-end write reads the latest Stop event where every turn row is built, so the
adapter's settle, the host's fallback and the relaunch's settle all agree: a turn a
person's Stop or close named, ending with no verdict of its own after that Stop, ends
as their cancellation. A relaunch's probe-bounded end is no earlier than a Stop that
found the turn running. When the provider refuses the interrupt and the turn runs on,
a refusal row answers the Stop, so a later crash still reads Failed; pressing Stop
again after a refusal is a new Stop.

* refactor(native-chat): a stop no longer carries its cause; the turn's end reads the Stop event

The cause of a stop was threaded in memory from each entry through the host's stop
step, the adapter router and each adapter's close onto the `ended` it settled with,
and Claude kept a per-turn copy of a Stop it sent. All of that is gone: adapters
settle a turn they cut as interrupted with no verdict, the host's fallback does the
same, and the one rule where a turn row is built (`turnEndAfterStop`) reads the
journal's latest Stop event to say whether it was a person's.

- `closeSession` / `disposeSession` take no cause; `ended` has no `stopCause`.
- Claude reads an error result after a person's Stop as their cancellation from the
  journal's Stop event (through the event sink), not from a per-turn slot, and a
  refused interrupt is the host's refusal row, not `withdrawTurnStop`.
- An owed wind-down keeps no cause: its retry's fallback reads the Stop event.
- The mutation context's Stop passes no cause: its step already wrote the event, and
  the delivery loop's child-end reason is read back from it.
- A Stop pressed before its turn showed applies to the turn that opens under it,
  unless a send a person made since was accepted.

* test(native-chat): a turn a later send opened is no Stop's that named no turn

* test(native-chat): the restart test's death proof carries its detail

* refactor(native-chat): a refused Stop leaves no record; a Stop only ever ends the turn it names

The stop-refused mark is gone: its tombstone kind, its fold, the clock-keyed match that tied it to
a Stop, and the exception that let a second press after a refusal write a new Stop. A Stop that
stops nothing writes nothing. A Codex refusal names a turn that is no longer its active one, and
the Stop names that turn, so the turn running instead never reads as the person's by its id alone.

* fix(native-chat): a Stop pressed before any turn showed stops only the turn opened next

A Stop that named no turn read as the person's cancellation for every later turn that opened
after it, until a send a person made was accepted. The queue's drain, orchestration mail and a
restart continuation send as the host, so a turn they opened long after, cut by a crash, read
"Interrupted" as if the person had stopped it. The Stop now applies only to the first turn
opened after it.

* fix(native-chat): an older Claude's error end after a Stop pressed before its echo reads Interrupted

Claude CLIs before 2.1.91 end an interrupted turn with an error result that names no reason. The
translator judged whether a person's Stop explained it by its own copy of the Stop rule, which
ignored a Stop that named no turn, so a Stop pressed before Claude echoed the send read "Failed".
The translator now writes such an end as interrupted with no verdict and no error row whenever a
person's Stop may name the turn, and the journal's one rule decides as it writes the end.

* fix(native-chat): a person's Stop and /clear each name why they end the agent

The host's mutation path ended the agent with one "recorded" ending for every caller, which read
back the reason of whatever Stop event the journal held last, however old. /clear writes no Stop
event, so its end took an unrelated earlier reason. Each caller now names its own: the chat's Stop
`user-stop`, whose event its own step wrote, and /clear `user-close`, the user replacing this chat.

* fix(native-chat): a host stop judges whether it ends work after the provider's rows land

A close, eviction or host stop decided whether it ended a running turn from the journal as it
stood, while the provider's own rows (the turn its echo opened) could still be in the session's
event sink. A close landing in that gap wrote no Stop event, so the turn it cut read as news. It
now reads after the sink drains, as a person's Stop does, through the same check; a drain that
fails or takes over a second reads working.

* fix(native-chat): a Claude Stop naming a turn that just ended still marks the follow-up it cuts

A phone names the turn it last saw. When that turn had ended and a follow-up was still unechoed,
Claude's Stop interrupted the follow-up and ended the child, but the Stop's event named the ended
turn, so the follow-up's turn the child's end cut read "Failed" under "Cancellation requested.".
A Stop that ends the provider's session ends whatever is in flight, so its event now names the
live turn or none, and a Stop that names none binds the turn opened next. Codex keeps naming only
the turn the Stop names.

The Claude Stop turn-end tests move to their own file, since the session-ending Stop suite is at
its line budget.

* fix(native-chat): the idle sweep reads working by the same rule as a stop's event

The sweep judged a chat resting while a send whose reply was lost was still unanswered, but the
stop's event writer counts that send as work. So the sweep evicted it and wrote an evict event,
which ends a person's Stop pause and let the cards behind it drain on their own. The sweep's owed
work now reads the main agent working the way every session list and the event writer do.

* test(native-chat): an aborted eviction's injected drain failure lands on the eviction's own drain

A host stop now drains the session's sink once to judge whether it ends work, so the tests that
fail the eviction's drain-published step skip that first drain.

* fix(native-chat): the idle sweep's rest writes no Stop event; it evicts a send that never echoes

The previous commit made the sweep count an unanswered send as owed work, which pins a chat whose
admitted send Codex never echoes forever, and the sweep exists to retire exactly that. That rule
returns. The sweep stops only an agent it judged resting, so its eviction now writes no Stop
event, whatever send it retires: a person's Stop pause holds through it.

* fix(native-chat): stopping a start that carries no send writes no Stop event

A host stop, eviction or close of a starting child wrote a Stop event whatever the start carried.
A start with a send already reads working, so the clause only mattered for a start with none,
which ends no turn and no send: its event only lifted a person's Stop pause and bumped the idle
clock, which is why the idle sweep had been changed to close the conversation in the same pass.
The clause goes and the sweep is #24072's again. The child's end still reads host-stop, as before.

* test(native-chat): a Stop's pause across a restart is tested with a restart that writes no event

The rig's restart closes the chat with an eviction, which now writes a Stop event when work runs
and so ends a person's Stop pause. "A Stop never hides a restart's pause" then passed with no Stop
pause left to hide anything. Those tests, and the pause-lift test whose dropped assertion returns,
restart as a process that dies with no close, which like a quit writes no Stop event, and assert
that both the Stop's and the restart's pauses are in force first.

* fix(native-chat): a host stop of a turn a person's Stop is still ending keeps that Stop's reason

An eviction or host stop that landed while a person's Stop or close was already ending the same
turn wrote a newer Stop event, and the turn's end reads only the latest, so the person's Stop of
that turn read as news. A host reason now writes nothing while a person's Stop still decides what
runs: the live turn it names or bound, or, with none, the turn a send opens next. The person's
own close still writes. The E2 tests now open and end the stopped send's own turn, as Codex does,
so the mail turn after it is not the turnless Stop's.

* fix(native-chat): an older Claude's error on a later turn keeps its error text after a Stop

The translator left an error result that names no reason to the journal's Stop rule whenever a
person's Stop named the turn or none, but the rule binds a Stop naming no turn only to the turn
opened next. So a real error on a later turn read "Failed" with its error text dropped. The
translator now asks the journal's rule itself (`personStopDecidesTurn`, the one core
`turnEndAfterStop` and a host stop's in-force check share), so the two cannot disagree.

* fix(native-chat): a Stop of a start that never landed binds no later turn, whatever sent it

A person's Stop pressed while the agent starts names no turn, and the send it stopped is
cancelled before it opens one. The Stop then bound the next turn anything opened (orchestration
mail, a restart continuation, the queue's drain, all of which send as the host), so a host
eviction of that turn wrote nothing and its crash or close read as the person's cancellation. A
Stop that named no turn now binds only a turn no send journaled after it opened: any send since,
of any origin and not refused, opens its own. The E2 test's mail send is accepted as Codex
accepts it, instead of opening the stopped send's own turn first.

* test(native-chat): a rewind's restated turnless Stop binds no turn opened after the rewind

A Codex rewind restates a person's Stop still in force after the turns it keeps, at a new
sequence, so by sequence alone it would bind the next turn opened after the rewind. A send
journaled after the restated row voids that binding (the previous commit), which this pins.

* fix(native-chat): a relaunch settles a person's stopped turn with no "stopped while in progress" row

After a restart, a turn a person's Stop ended reads "Interrupted after N" with the muted mark, but
the relaunch still added the error row saying the provider stopped mid-response, which a live Stop
never writes. The settle now skips that row when every turn it interrupts is the person's Stop's
by the journal's one rule; a crash nobody stopped keeps it.

* test(native-chat): the unexpected-exit settle's journal fake answers whether a person's Stop decides a turn

* fix(native-chat): a host stop whose sink drain fails reads the journal as it stands

A host stop drains the session's sink before judging whether it ends work, and a failed or slow
drain read as working. So an eviction of an agent at rest wrote a Stop event that ended nothing,
which lifts a person's Stop pause, and a close wrote a person's event naming no turn. The drain is
now best effort: the stop goes ahead either way and only its record is at stake, so a failed or
slow drain leaves the journal's read as it stands. A person's Stop keeps its own rule.

* fix(native-chat): a Stop that named no turn applies only to a turn a send it stopped opened

A person's Stop pressed before any turn showed names no turn. It bound the first turn opened
after it, then (5ead1f6bcc) any turn opened by no later send, so a turn the host started for
a card the Stop held, or for orchestration mail, read as the person's cancellation, and a host
eviction of it wrote no Stop event when its send had been abandoned by the close first.

The rule is now the concept itself: a Stop naming no turn applies to a turn opened by a send it
stopped, one already handed to the agent at the Stop's position. Nothing new is stored. The turn's
row names the send that opened it (Codex: the submission's key; Claude: the echo, which the journal
aliases to the submission), and a handed-over send's item sits at its handover, so the target set
is derived from the journal. A card the Stop held is handed over after it, so it is no target; a
Stop of a start whose send never opens a turn binds nothing; a rewind keeps no submissions, so a
restated Stop binds no turn opened after it. With no turn running, a host stop defers to the
person's Stop only while every unanswered send is one it stopped. Claude's translator, which asks
before its echo row lands, passes the send its echo acknowledged.

* fix(native-chat): a host stop whose sink drain runs long reads the agent working; a failed one reads the journal

A drain past its bound may still hold the turn's row, while the echo's acceptance has already
landed, so the journal as it stands read nothing running: a person's close of that turn wrote no
Stop event and the turn read as news. The two drain outcomes now differ: one that failed has
nothing more to deliver, so the journal's read holds (as before); one still running reads working.

* test(native-chat): a host stop with no turn running defers only while every unanswered send is the Stop's

The branch had no test. An eviction with only the stopped send unanswered writes nothing; one
with a send made after the Stop still unanswered writes its event.

* fix(native-chat): a slow sink drain reads working only while an accepted send's turn row is due

The previous commit read every drain past its bound as working, so a host eviction or stop of an
agent at rest during a sink backlog wrote a Stop event that ended nothing and lifted a person's
Stop pause. A slow drain now reads working only when the latest send the agent accepted has opened
no turn the journal holds, the race it was for; otherwise the journal's read holds.

* test(native-chat): the host-stop control keeps the stopped send unanswered beside the later one

With both unanswered, the host writes only because not every unanswered send is the Stop's; a rule
that deferred when any one was would pass the old control.

* fix(native-chat): a steer is no send owed a turn when a slow drain judges a host stop

A slow drain reads working when the latest accepted send has opened no turn yet. A Codex steer or
a Claude fold is accepted into the running turn and never opens one, so a chat at rest whose last
send was a steer still read working, and an eviction lifted a person's Stop pause. Sends delivered
into a running turn, whose item carries that turn's scope, are skipped.

* feat(native-chat): a chat reads Stopping from the person's Stop until the work it stopped ends

The host derives it on each journal publish from the Stop's event, the live turn and the Stop's
own answer, and publishes it as an optional field on the session status and the main agent's row.
Clients present it: the chat's tail line and Stop control, the sidebar row, worktree ps and the
phone's row. The chat and the phone also read their own Stop press until its request answers.

* test(native-chat): pin Stopping on the phone and across mixed versions

* test: give touched fake journals and mocks their SAFETY notes

* test(native-chat): a turn waiting on the person reads attention, never Stopping

* test(native-chat): the sidebar row follows Stopping when it is the only field that moved

* test(mobile): the phone reads Stopping from its own Stop until the request answers

* test(mobile): type the held Stop request instead of casting it

* chore: keep the base lockfile (a local pnpm run rewrote it)

* fix(native-chat): narrow the Stop note's optional failure; type the phone test's reply

* test(native-chat): type the Stop test envelope's fields narrowly

* fix(native-chat): a Stop the agent declined, or whose child end failed, says so while the turn runs on

A Stop naming the turn that still runs, refused by the agent, now writes the
Stop's refused fact instead of 'already finished'. A session-ending Stop whose
child end fails while the work runs on revises its note to unconfirmed.

* fix(native-chat): Stopping holds while any press of the Stop took

A repeat press refused after an earlier press took no longer clears Stopping.
Exit early when the Stop named a turn that is not the live one.

* fix(native-chat): keep Stop enabled while the host says Stopping

Only this client's own Stop request in flight disables Stop and Esc. A repeat
Stop is how a stop the provider took but never answered escalates.

* fix(sidebar): every agent row says Stopping in place of its tool line

The dashboard row, which the sidebar's non-compact mode also draws, read the
last tool line while a person's Stop ended the turn. It now shares the compact
row's rule.

* fix(mobile): the worktree list sees Stopping change on its own

A snapshot whose only change was the host dropping Stopping compared equal and
was thrown away, leaving the row on Stopping.

* refactor(native-chat): fold the status feed in src/shared for both clients

The snapshot merge and the contact-loss strip move out of the renderer feed so
the phone folds the same stream the same way.

* feat(mobile): let phones read the structured session status stream

agentSession.subscribeStatus joins the mobile allowlist. The agent-session
methods move to their own file, which the at-cap allowlist spreads in, and the
allowlist test reads the Set instead of parsing the source.

* feat(mobile): the phone chat reads Stopping from the host, like the desktop

One status stream per client, opened on a host that advertises the status feed;
a refusal to phones reads as no feed. The chat reads Stopping from the host or
its own press, and holds Stop only while its own request is in flight.

* test: give the new fakes checked types or a SAFETY reason

* revert(native-chat): drop the refused-named-turn rewrite of a Stop's note

Codex can send its refusal before the turn's end frames, so reading the turn as
still live after a flush races; the Codex Stop that ends nothing is handled by
ending the process instead. The base's 'already finished' note and its test
expectation return. The Claude wind-down failure revise stays.

* fix(mobile): release the status stream when the host ends it; refusals last one connection

The feed now drops the handle of a stream the host ended or refused, so the
logical client never replays it on a later session. A refusal to phones holds
for one connection, so a host updated while the phone stays paired is asked
again.

* perf(native-chat): read the live turn's opener from its record when deriving Stopping

After a Stop that named no turn, every later commit walked and copied the whole
journal to find the live turn's record. The derivation now reads that record
off the rendered snapshot's tail and decides with the same rule.

* refactor(mobile): move the method-unavailable check into transport

The status feed imported it from the Files tab's fallback. No behaviour change.

* test(native-chat): a send after a Stop reads Working before its turn opens

Pins the derivation's running-only read of the newest turn: the stopped turn,
already ended, must not keep the next send on Stopping.

* fix(sidebar): the compact row leads with Stopping so a narrow sidebar keeps it whole

At the default width the row read 'Codex Chat - Stoppin…': the model and time
keep their room and the line truncates from the end. Stopping now leads the line
the way monitoring already does, so the chat name is what gets cut. Also pins
that the turn bar keeps its running clock while the tail line says Stopping.

* test(native-chat): the retry of a close whose exit was unproven writes no second Stop event

The idle sweep finishes a stop left owed with that stop's own cause. It is the same stop, so its
event stands alone and the child's end keeps the cause, for a person's close and an eviction.

* fix(native-chat): read and write a Stop's answer by the turn its event records

Stop notes are now one row per turn, keyed by the turn the Stop's event
records. Performing a Stop and deriving Stopping share that key. A refused or
unconfirmed answer never overwrites one that took at the same key; only a
session-ending Stop's failed wind-down downgrades it, and that step now revises
the note the Stop actually wrote, carried on the wind-down. Stopping reads the
turn's note whenever it was first written, plus newer notes no other turn owns.
Test fixtures gain the host logger and the phone's quietRepeatedStop.

* refactor(native-chat): read a Stop's target once for its event and its note

The chat's Stop now reads what it is aimed at (the named turn and whether the
Stop ends the provider session) once, and both its event and its note's key
derive their turn from that one value through the same rule. Adds the host test
for a Stop naming an ended turn on a provider whose Stop ends the session.

* fix(native-chat): the host never steers a message into a turn a Stop is ending

A queued card's Send-now, or a send made while a person's Stop ends the turn,
went to the agent as a steer into that turn. The delivery loop now holds any
waiting message while the host's own Stopping reading holds, and sends it as
its own turn once the turn ends. The Stopping reader also stops at the Stop's
position and looks the turn's note up by key, instead of walking the whole
journal.

* feat(native-chat): while Stopping, the composer says a message runs after the stop

Desktop and phone: the composer placeholder reads "Queue a message to run
after the stop" while the chat reads Stopping, and a queued card's Steer (and
the desktop's steer shortcut) is held. New key translated in all 6 catalogs.

* refactor(native-chat): the chat pane's Stop controls live in their own module

The pane went over its line limit once merged with main. Its Stopping reading,
the press that holds Stop, and the steer and placeholder it hands the composer
move to native-chat-structured-stop-controls.ts.

* fix(native-chat): hold a send at its handover, reading the feed's own Stopping

The hold was checked when the delivery step started, but the handover runs in a
later step after waiting on the agent's start, so a Stop landing in between let
a new send steer into the stopping turn. The check now runs at the handover.
It reads the status feed's projection for the commit instead of rendering the
journal again, so holding a send adds no journal read of its own.

* refactor(native-chat): one display status decides Stopping on every surface

agentStopDisplayStatus combines whether the agent works, the host's flag and
this client's own press. The chat pane, sidebar and dashboard rows, and the
phone's chat all read it, instead of each combining the flags.

* fix(native-chat): Stopping holds until the stopped turn ends, whatever the Stop's answer

A Stop the agent declined, or whose end went unconfirmed, used to drop the chat
back to Working. It now stays on Stopping until the turn ends, and Stop stays
enabled so a repeat press escalates. The Stop's answer is no longer read for
Stopping, so its note goes back to the key the base gives it (the restore of
queued-stop.ts and the removed key test landed in the previous commit). The
note still keeps a press that took over a later refusal, and a failed process
end still says the Stop went unconfirmed.

* fix(native-chat): a Stop binds only the turn it actually stopped

A Stop pressed before any turn showed used to claim, at end-write time,
whatever turn the stopped send later opened, even when the Stop stopped
nothing. A turn that then died on its own read as "Interrupted" (your
cancellation) instead of "Failed".

Now a person's Stop that named no turn binds, in memory only, every turn
that ends while the Stop settles, and afterwards only the turn its
interrupt took. The settle ends a still-running stopped turn once. A
relaunch finds nothing in memory, so an unsettled turnless Stop binds no
turn. A Codex Stop whose answered turn does not open within its wait, or
whose send's answer was lost, now answers refused, so the host ends the
child and the turn can never run.

* fix(native-chat): keep the person's queue pause and close binding after a Stop settles

A host stop or eviction with no turn running now defers to a person's
Stop while its queue pause still holds with nothing sent since, read from
rows, so a held card is not handed off on reopen after a Stop that did
nothing or whose kill failed.

A person's close that named no turn opens a settle around its child's
end, so a turn that end cuts reads as theirs.

A press opens its settle only when the latest Stop event is its own or
the one in force it repeats: a late Stop, a card's interrupt or a lost
event row reopens no earlier Stop.

A Codex Stop that cannot reach a turn still able to open says the Stop is
unconfirmed rather than that no turn ran, and a second Stop still reaches
a turn an earlier wait left unopened.

Also drops the unused openedBy plumbing and the unreachable "a written
cancellation stays one" rule, and pins a relaunch after a named Stop.

* fix(native-chat): keep a failed Stop's turn display-only, and settle edges off the commit path

A Stop that failed marks the turn it could not stop for "Stopping…" only
(JournalStopSettle.failedOn): no turn-end rule reads it, so that turn's
own end with no verdict reads as a failure, not the person's.

A settle edge writes no row, so it no longer goes through the journal's
commit listener, which also delivers history, counts as activity for the
idle sweep and schedules the queue drain. A narrow settle-edge hook
republishes the status row and wakes the steer hold's handover, and
nothing else.

* fix(native-chat): a Codex Stop agrees on both presses when a turn is still owed, and pin the close's settle

A Codex Stop that waited for a turn Codex answered a send into now answers
"may still open" whenever that turn neither opened nor ended and its send
is still owed, however the wait ended (it ran out, or the thread went
idle). Before, a first press after an idle thread said no turn was
running and kept Codex, while an identical second press ended it.

Adds a test that a person's close the conversation outlives (as /clear
does) closes its settle, so a later turn that ends on its own reads as a
failure.

* fix(native-chat): a Stop that failed before its turn showed still reads Stopping through that turn

A Stop that failed with no turn open marked nothing, so the chat dropped
to Working and the turn that then opened never read "Stopping…". The
display-only mark now also covers that case: the first turn that opens
after the Stop failed, provided no message was handed to the agent in
between. No turn-end rule reads the mark, so that turn's own end with no
verdict still reads as a failure.

* test(native-chat): a Stop whose event row failed binds no turn to an earlier Stop

With one ordered journal writer the Stop's event is in the fold when its
write returns, so the press reads whether it owns the latest Stop from the
fold instead of awaiting the write. Pins the case the read must refuse.

* test(native-chat): name the settle, not a stream drain, in the Stop's own-end test

* test(native-chat): a Codex Stop answered before Codex ends the turn reads interrupted throughout

Codex answers an interrupt it took before it sends turn/completed (interrupted):
on TurnAborted the app-server answers pending interrupts, then ends the turn, on
one channel. The test fake did the reverse. It now answers first and ends the
turn on a later read, and the tests that read the turn's end right after a Stop
wait for it.

New end-to-end test through the shipped host, journal and Codex adapter: with
the real order, every end row of the stopped turn reads interrupted by the Stop
(named, unnamed, and a Stop pressed while turn/start was in flight). Breaking the
settle window turns the in-flight case red: the Stop's own end row then has no
verdict, which reads as failed until Codex's end lands.

* test(native-chat): Stopping ends with a Codex turn whose interrupt is answered before its end

With Codex's real order (the interrupt's answer, then turn/completed interrupted),
the status shows Stopping while the Stop settles, drops it once the turn ends, and
never carries a verdict other than the person's cancellation.

* fix(native-chat): a Codex Stop interrupts a turn Codex answered but has not opened at once

A Stop that named no turn, made after Codex answered a send but before the turn
opened, used to wait up to 5 s for the turn to open before interrupting, and
ended the Codex process when it didn't. The stated reason, that Codex refuses an
interrupt until it opens the turn, holds only part of the time: with no turn
active, Codex takes an interrupt once its thread runs (turn_interrupt_inner),
and refuses it with -32600 "no active turn to interrupt" before that or once
the turn has ended.

The Stop now sends the interrupt at once. Only on that refusal, while the turn
has neither opened nor ended, does it wait for the turn to open (bounded at
5 s) and send it once more. A turn that ended meanwhile was nothing to stop. One
that never opens, or that an earlier wait already gave up on, fails the Stop,
and the host ends the child as before. Sends still wait for the turn to open
before steering into it.

The test fake models Codex taking an interrupt once the thread runs (run()).

* fix(mobile): name how the phone's status stream is released in the subscription inventory

Main made each inventory entry state its release; the status feed's stream is
released from its subscribe params, as the session event stream is.

* fix(native-chat): every Codex Stop waits for an answered turn to start, as the first did

A Stop whose interrupt Codex refused as finding no active turn skipped the wait
when an earlier wait, a Stop's or a send's, had already given up on that turn.
Every press now waits its own bound and retries once if the turn starts, so a
turn that opens during a later press is still stopped. Both presses still reach
the same verdict when it never starts.

* fix(codex): never steer a turn whose interrupt Codex answered

Codex answers an interrupt as the turn aborts, before it sends that turn's
turn/completed. In that gap the adapter still counted the turn as running, so a
message handed over right after a Stop settled (the Stop's own end row already
reads the turn ended) went out as turn/steer, which Codex refused with -32600
"no active turn to steer", and only then as turn/start. The adapter now marks a
turn whose interrupt Codex answered as aborted until its turn/completed, never
steers into it, and starts the message's own turn directly. Steering a turn
that is genuinely running is unchanged.

* fix(native-chat): a message sent while Stopping is queued as a card, whatever the setting

While the chat reads Stopping (the host's flag or this client's own Stop in
flight) there is no turn left to steer into, so the desktop asks the host to
queue the send even with the queueing setting off, and it is never drawn as a
bubble inside the turn being stopped. The phone already queued every send on a
capable host; a test now pins that it does so while Stopping.

* fix(native-chat): a message queued while Stopping is a card at once, not after the stop

A person's Stop holds the session's lane until Codex answers its interrupt, and
a send was admitted only behind it. By then the turn read ended, so a send that
asked to be queued went out plain: no card for the whole of Stopping, then a
bubble and a new turn.

While the host reads that a person's Stop is ending the work, a text send that
asks to be queued is admitted without waiting for the lane: the same ledger and
lease admission, and a plan that only writes the card through the journal's
ordered writer. The card runs when the stop lands; the Stop's pause holds only
cards queued before it. Anything else, including a Stop that settled by the
time the send runs, takes the lane as before.

The Codex test fake now drops the active turn when it takes an interrupt, as
Codex does before it answers, so a turn/start after the answer opens a new turn.

* fix(native-chat): a Codex Stop that ends the child before any turn opened withdraws its send

A Stop on a Codex turn that was answered but never opened ends the Codex
process. That end settled the send as in doubt (unknown, recovered), and the
client's outbox holds every later send behind a send in doubt until the person
presses Retry, which re-sends the very message they stopped. The chat looked
stuck.

Codex records a prompt only once its turn has started, so a send whose turn
never opened never ran. When the Stop's refusal says so (turnMayOpen), the child
end now settles the unanswered sends as withdrawn, the verdict Codex's own
interrupted-turn end already gives an unechoed send. The flag rides on the owed
wind-down, so a retry after a failed child end withdraws them too. Claude's
child end still leaves its unanswered send in doubt.

* fix(native-chat): derive the withdrawal of a Codex send whose turn never opened

Replaces the flag the Stop carried to the child's end, and its copy on the owed
wind-down, with a reading of the journal at the settlement that lands. A Codex
child's unanswered send is withdrawn when a person's Stop is in force since it
was sent and no turn row ran, or was written, after it; any other end (a turn
that opened, a host's close, a crash, Claude) still leaves it in doubt. A
retried wind-down reads the same rows, so it withdraws the same sends.

* fix(native-chat): a card queued while Stopping runs past the cards the Stop holds

A card queued before a person's Stop waits under its pause until Resume. One
queued after it, as a message sent while Stopping now is, was stuck behind them
too, since the queue never reorders. Such a card was asked for after the Stop,
so it runs when the stop lands, past the cards held only by that Stop's pause;
a returned card and the restart and /clear pauses still hold everything behind
them.

Also: the host's own Stopping reading is gated on working, as the published
flag is, so a failed Stop's mark never reads Stopping on an idle session; a send
that falls back to the lane re-reads the conversation's journal there; and the
end-to-end test asserts the queue's pause rather than a per-card field.

* fix(native-chat): a paused queue labels only the cards it holds

Since a card queued after a person's Stop runs past the cards the Stop holds,
labelling every card "paused" while the queue's pause is published misreads that
card. The host now marks each card its pause holds (heldByPause, a new optional
field), and the desktop and phone label only those. An older host marks none,
so a client keeps today's labels; an older client ignores the field.

Adds a test of the desktop's own send through the real outbox: while the chat
reads Stopping, the request asks the host to queue it and no bubble is drawn,
on a host that advertises the queue.

* revert(native-chat): defer the per-card queue pause label to the queue's rollout

The heldByPause field and its labels are visible only where the host
advertises the queued-messages capability, which shipped hosts do not yet do.
Deferred to that rollout; the real-outbox send test stays.

* fix(native-chat): while Stopping, say and show what a send does where the queue is dark

Shipped hosts do not advertise the queued-messages capability, so a message
sent while Stopping goes out plain: the host holds it until the stopped turn
ends and then runs it as its own turn. The composer still said "Queue a message
to run after the stop", and the message was drawn inside the turn being
stopped.

Now the placeholder reads "Send a message to run after the stop" where the host
does not queue sends, and "Queue a message…" only where it does (desktop and
phone, all six catalogs). A send this client made that the host has not
recorded yet is drawn after the Stopping line while the chat reads Stopping, as
a message held behind a running command already is; once the host hands it
over it opens its own turn. Client presentation only.

* fix(native-chat): keep a send in doubt when a turn was open for it

The derived withdrawal read a turn as open for a send only if it still ran or
was written after the send. A send steered into a running Codex turn whose
interrupt failed met neither once the adapter's end settled that turn ahead of
the host's settle, so it read withdrawn, though Codex drains a steer into the
running turn and may hold it. A turn that ended after the send was handed over
was open for it too: such a send stays in doubt, as before.

Pins that case, and that a send made after the Stop, to a child that then dies
before its turn opens, stays in doubt.

* fix(native-chat): restore the per-card queue pause label

Kept after all: a paused queue labels only the cards it holds (heldByPause),
which is visible only where the host advertises the queued-messages capability.

* fix(native-chat): draw only a send made while Stopping after the Stopping line

Every send the host had not recorded yet was drawn after the Stopping line,
including one made just before the Stop, which the host steers into the turn;
it then jumped up into that turn once recorded. The outbox now marks a send
made while the chat reads Stopping, and only those wait after the line.

* fix(native-chat): withdraw a Codex send by whether it started its own turn, not by timing

Whether a turn was open for a send was read from end times: a turn that ended
after the send's handover counted. A send made while a Stop ended the turn is
handed over once that turn reads ended, yet Codex's own end for it can arrive
later, so such a send whose own turn never opened read in doubt again, and the
chat's queue held behind it.

The handover already records where the send went: its message joins the turn
running then (a steer) or belongs to no turn (it starts its own). Only a send
that started its own turn, with none opened since, is withdrawn; one that
joined a running turn, or has no recorded place, stays in doubt.

The Codex test fake takes an answered interrupt as Codex does, dropping the
turn before its end arrives.

* refactor(native-chat): move queue-while-stopping to its own follow-up

The queued-messages capability is off on every shipped host (#21062), so the
parts of this PR that act only when it is on move to a follow-up stacked on
this one: admitting a queued card while a Stop holds the session's lane, a card
queued after a Stop running past the cards it holds, the per-card pause mark,
and asking the host to queue a send made while Stopping. This PR keeps the
Stopping state, the host's steer hold, the rule that never steers a turn whose
interrupt Codex answered, and what a send while Stopping looks like where the
queue is off.

* fix(native-chat): leave no Stop row when the Stop took back a send that never ran

A Stop on a Codex send whose turn never opened ends the child, and the child's end
takes the send back into the composer. The Stop still wrote "Cancellation
requested." at the conversation level, so with the send gone it sat under the
previous finished turn and read as if that turn had been stopped. A Stop that found
no turn running and whose child end took back every send it found now writes no
row; a Stop of a running turn, or one that leaves a send in doubt, still does.

* fix(native-chat): count a send whose answer was lost when a Stop takes it back

The no-row rule counted only pending sends, but the child's end also takes back a send this process left in doubt when Codex's turn/start answer was lost. That case still wrote "Cancellation requested." under the previous turn. Both now read one predicate, so they cannot drift apart.

* test(native-chat): pin which sends a Stop's child end can take back

A send an earlier process left in doubt is never withdrawn and never holds the row back, and a queued card's send is never counted.

* fix(native-chat): hold the next handover while the send ahead opens its turn

The delivery loop handed queued messages to the provider back to back. Codex steers a second send into the first one's turn once it opens, and Claude folds it into the running cycle, yet its handover row was written before that turn existed, so it read as belonging to no turn and was drawn ahead of the reply. The loop now hands the next message over only once the send ahead has opened its turn, settled, or been stopped, all read from the journal; each is a commit, which wakes the loop again. The message then goes in scoped to the opened turn.

* fix(native-chat): doubt a Codex send whose turn never opened once Codex goes idle

A Codex before 0.148 fails a turn before opening it with only an error. The send stayed pending, and the hold behind it waited on it. When Codex reports its thread not running with no turn open, a send answered into a turn it never opened or ended now settles as doubt with the existing idle reason, which releases the hold. No clock: a slow but healthy turn start is never doubted.

* fix(native-chat): end an unopened Codex turn on its final error, not at idle, and drop the Stop release

Codex publishes the thread idle ahead of turn/completed, and between an aborted turn and the next picked one, so releasing at idle doubted sends in turns Codex did open or was about to. A final error naming a turn Codex never opened (its only end before 0.148) now ends that turn as failed instead, settling its send as a turn/completed failure would. The test fake publishes idle before turn/completed, as Codex does. A Stop no longer releases the hold: the seven rig tests that needed it now settle the stopped send the way the provider does.

* docs(native-chat): put each turn-end settlement comment on its own function

* test(native-chat): echo the first send before the next in the restarted-child test

The test's child admitted the first message and never answered it, which no live provider does; the next send was then held behind a turn still opening. The child now echoes the first message, so the test still checks that the next send restarts nothing.

* fix(native-chat): draw a message held behind an opening turn after that turn's live status

While the send ahead was still opening its turn, the live turn was taken to be the newest user message, the held one, so its live status drew under the held message and the held message drew above it. While a send is opening, its turn is now the live one, and messages sent after it, queued or not yet recorded, wait behind the live turn as a message held behind /compact or a Stop does. The host's hold and the client's drawing read one shared predicate.

* fix(native-chat): keep held messages waiting while Stopping, and leave Retry-only sends in place

While Stopping, a message typed then returned early from the waiting rule, so a message held behind the opening turn moved back above the Stopping line. The rule now waits the union of both. A send only the user's Retry sends again is not held by the host, so it no longer waits behind an opening turn; the projection marks it.

* fix(native-chat): keep a turn on the send that opened it when Codex echoes a steer first

A message held behind an opening turn is steered in moments after that turn opens, and
Codex can echo the steer before the send that opened the turn. Both carry the turn's one
provider key, so the steer was read as the turn's opener: for that moment the live status
moved under it and restarted its clock. While the opener is still in flight ahead of the
turn record, a steer into that turn no longer takes it.

* fix(native-chat): never anchor an opening turn on a message still queued above its send

Two messages queued behind /compact, or sent while Stopping, are accepted above the first
send's handover, and the hold makes the first send's turn record land before the second is
handed over. The turn fell back to the first unechoed send ahead of its record, which was
the queued one, so its live status moved under it. A send still queued is not in flight.

The phone keeps no outbox, so its frame tests now draw only recorded rows, through the
phone's own fold rather than the desktop's transcript order.

* fix(native-chat): read the host's Stopping beside main's startup phase

Main now reads only the startup phase from the status feed and no longer publishes which
child is starting. The chat reads the host's Stopping from its own hook beside it, and the
Stopping bridge test mocks the execution-host lookup main's owner resolution now calls.

* test(orchestration): open the working send's turn before a `now` send joins it

The rig's working send was handed over with no turn record, so the running turn the test
names never existed; the hold rightly kept the `now` send until that turn opened. The setup
now opens it as a provider does. The assertions are unchanged.

* test(native-chat): pin the phone's own echo of an accepted send behind an opening turn

The phone keeps no outbox, but it does show its echo of a send the host accepted until that
send's row arrives, and the shared waiting rule moves that echo behind a turn still opening.
The phone test now builds its list as the phone's view does, echoes included, and covers it.

* test(native-chat): read the outbox reconcile from where main moved it

* test(native-chat): pass the projection's options after main's rejected-in-place rows

* fix(native-chat): a retried message no longer waits behind a later Stop

Retry dropped the Stop it had outlived but kept the mark that it was sent while
a Stop was ending a turn, so a retried message waited behind whatever later,
unrelated turn a Stop was ending. Retry is a new send: drop that mark too.

* fix(native-chat): word a send after a Stop by whether this send will queue

The 'queue a message to run after the stop' placeholder read the host's
queue capability alone. A send queues only when the host queues and this
send asks it to: the queue setting is on and no pending prompt blocks the
queue. Desktop and phone now word the placeholder from that same decision
their send uses.

* test(native-chat): one test per case for the words of a send after a Stop

* refactor(native-chat): the dictation hook owns the composer's dictation state

Keeps NativeChatComposer within its line limit after the Stop props and
main's /context answer both landed in it.

* refactor(native-chat): name the dictation hook for what it owns now

* fix(native-chat): a Stop's note says it took once a joined close proves the exit

A session-ending Stop whose child's end failed revises its note to
'unconfirmed'. Since main's #24862, the next Stop joins that close rather
than stopping again, and wrote no note, so a close that then proved the
exit left 'unconfirmed' under a turn that ended. The close now carries
the note it settles, and its proven exit revises it to 'Cancellation
requested.'. A join that fails again leaves it unconfirmed.

* fix(native-chat): a proven turn end says a Stop's unconfirmed note took

Replaces the note carried on the child's close. Every settlement that
ends turns interrupted on a proven exit, live or after a crash, also
revises an unconfirmed Stop note on those turns to 'Cancellation
requested.', found by the note's turn scope, in the same batch. A note a
Stop wrote before its turn showed is re-keyed onto the running turn when
it becomes unconfirmed, in one batch, so that end finds it. Known limit:
with no turn open yet, the note keeps its key and no turn's end revises
it.

* test(native-chat): a Stop's unconfirmed note says it took when the agent exits on its own

* test(native-chat): a message that joins a Stop's unproven Claude close goes to the resumed child, the next waits for its echo

Covers the case main's #24862 retired with its unproven-stop test: the
first message after an unproven close joins it and reaches the resumed
child, and a second waits for that message's turn to open.

The Stop control now disables itself while Stopping, so the composer passes
the flag through and its test file stays as main has it. The phone chat
header's Stop moves to its own component.

* perf(native-chat): read a Stop note's fields before parsing its key on every snapshot

Every snapshot projects each item through the Stop-note read, and each new
snapshot rebuilds the index of Stop notes by turn. Both parsed every item's
key first; they now check the row's kind and turn scope (and, for the
projection, its unconfirmed-stop failure) before the parse. Every Stop note
is a status row, so what each finds is unchanged.

Brennan Benson 2f49377425 feat(native-chat): Grok as a structured chat over the Agent Client Protocol (#25225)
* Leave a stopped turn's running tools to the agent's own end

When another writer settles the open turn (a person's Stop), the assembler
now only stops that turn's text and cancels its pending prompts. Running tool
calls stay the agent's: a progress update or completion it reports after the
Stop lands as reported, and whatever is still running settles at the agent's
turn end for that turn, the next turn's open, or the session's end.

An agent's end for an earlier turn while a newer one is open no longer clears
the open turn's activity line or ends its anonymous reply. An unnamed end right
after a Stop ends the stopped turn instead of being dropped. The test rig's
restart no longer writes the dead assembler's window text, matching dispose.

* Pin that a stopped turn's running tools hold budget until the agent's end

* Type the stopped turn's tool progress update as a tool body

* List every event the assembler hands to the decision step

The type-aware lint requires an exhaustive switch with no default case.
Also retitle a Stop test to say what it asserts.

* End a running call as its turn's journal row ends

A call still running when its turn ends takes the state of that turn's
row: a row another writer settled first (a person's Stop) stands, so its
calls read interrupted whatever the provider's later end reports. The
no-ending path that settled calls from the Stop row is gone, since a Stop
now leaves running calls to the provider. Adds the two Spanish strings.

* Say why a Grok turn failed, and keep task rows in Grok's own words

A failed Grok turn ended with no reason on screen: the translator dropped
every copy of Grok's message. The failed turn now gets one status row in
Orca's existing "provider did not accept this message" words with Grok's
reason, read from whichever copy arrives first (the given-up retry, the
turn's end, the prompt's completion notice, or the prompt's error answer);
later copies only fill a reason the row still lacks.

A running background command no longer reads "Background task <id>
started": a task's summary is mapped only once it has settled. A monitor
stays a monitor when the agent reads its output: a frame that names no
kind keeps the known one, and a "[monitor" command is a monitor.

A prompt's turn is marked started, so a late frame for an ended prompt
neither reopens it nor becomes the active turn. A tool's turn is held in
one place at a time.

* Read a monitor from Grok's exact output prefix

* Word a failed Grok turn in Grok's own text, not as a refused message

A turn that started and then failed was told "The provider did not accept
this message", Orca's sentence for a message refused before its turn. The
row now reads as a Codex turn-ending error does: an error status row with the
provider's own words. With no words, the dialect names the failure ("Grok
ended this turn with an error." / "Grok usage limit reached."), else the
agent's display name does.

* Settle a stopped turn's running call as its turn row ended after a restart too

The restart sweep ended every running call by the death evidence alone, so after
a person's Stop with no proof the child died the call read failed under a turn
that read interrupted. The sweep and the live dead-generation settlement now ask
the same rule the assembler does: a call in a turn already settled ends as that
row ended; only a turn still running leaves its calls to the evidence.

* Keep the dead-generation settlement under the line cap

* Register the ACP schema verify step in the PR preflight phase test

* refactor(agent-session): one required agent registry; declarations admit what they claim

A StructuredAgentRegistry, built once from the {definition, adapter}
registrations, is now a required host dependency and the router routes with
it. The adapter interface loses its optional router-only capabilities?() and
definition?(); every reader (options at rest, thread goal, rewind, the
/compact handover) asks the registry. A live session still narrows rewind
through the adapter, and the host combines declared and narrowed in one
helper. The registry refuses a registration that declares compact, a thread
goal or rewind without the adapter method behind it.

/compact is admitted by the declared capability, so an agent that declares
compact:false gets the commandRefused fact instead of a thrown error.

Also: the cut-turn notice names the agent from the catalog, create-support
builds the account home through agentSessionAccountHome, and the turn
status text older clients read names the session's agent instead of
defaulting to Codex (Claude/Codex text unchanged).

* Read ACP permissions, session events and prompt errors through the protocol client's own types

The translator now reads a permission request with the client's lenient reader, a session update
with its session-event reader, and takes only the agent's own error answer as a failed prompt's
reason, so an Orca-side error never reads as the provider's words. Tests cover protocol values
newer than this build.

* refactor(agent-session): the router applies the declared rewind itself

The router holds the registry, so its rewindSupport answers the owner's
declared rewind narrowed by the adapter, in one place no reader can bypass.
The host-side combining helper is gone; readers ask the adapter they hold.

* test(agent-session): register the agents the merged-in tests now need

The adoption replay test builds its host over this build's registered agents
instead of an adapter definition method, and the stored-form test passes the
stored agents the record guard now requires.

* chore(agent-session): the registry is the one lookup; drop the test-only empty capability record

* fix(agent-session): keep "dismiss all" restart offers dismissed for the desktop

The desktop renderer calls the restart methods as a paired runtime client
without the registered-agents capability, so it was handed a Claude/Codex
audience and its "dismiss all" took the scoped path: no dismissal fence and
no clearing of unwritten teardown witnesses, so a late teardown write could
bring a dismissed offer back.

The audience is now derived against this host's registry: a client that can
show every agent the host registered gets none, and dismisses exactly as
before (one fence for every offer). A client that truly cannot show some
agent still gets a final dismissal for what it sees: each cleared session is
fenced on its own (bounded, superseded by a dismiss-all fence) and only the
witnesses of agents it sees are dropped.

One predicate now answers which agents a client renders, for both tab
projection and restart offers; the Claude capability rule is folded in.

* fix(agent-session): a changed agent definition never hides that agent's chats

A record was readable only if every handle used the transport its agent's
definition declares today, and its account variable was declared by some
registered agent. A later build that drives the same agent over another
protocol, or under a renamed variable, would have set every existing chat of
that agent aside: no tab, no history, no error.

Readability now asks only that the record agree with itself: its agent is
registered, every handle shares one namespace owned by that agent, and the
account variable is a well-formed name. Whether this build can drive it (the
chain's transport is the one the agent speaks, and the account variable is
that agent's own, since it becomes the child's environment) is decided in
performAttach, the one admission every start of every agent passes through,
and refused there as hostUnsupported. A record pinning another agent's
variable is refused the same way rather than passing because some agent
declares it.

* refactor(agent-session): each agent's registration says where it runs and which account it pins

createSupport, create and the model catalog's account read still chose a
location rule and an account resolver by name (Claude, Codex, else none),
so a new agent would have needed a third branch beside the registration
list that already decides storage, routing and publication.

Each runtime registration now carries supportsLocation(location) and
resolveAccountHomePath({ launchEnv, location, purpose, workspacePath }),
and Claude's and Codex's rules move into their entries unchanged: a read
still syncs no home and starts no bridge, a Codex launch still trusts the
workspace first, and WSL locations resolve as before. The list exists
before the host is built, so none of these reads installs the host, and an
agent the list does not hold is answered no without opening the journal.

* test(agent-session): drop a duplicate registry key; keep fences out of the capsule state

A spread input already carries the registry, so the explicit key was
overwritten (TS2783). The session-fence helper now returns only the fence,
not the capsule state it was given.

* fix(agent-session): a scoped dismiss-all persists no per-session fence

The per-session dismissal fence added a forever-persisted capsule field
with an arbitrary cap that served no caller: only the local desktop calls
the restart methods, and on a host whose agents it all shows it gets no
audience and takes the unscoped, fenced dismissal. A scoped dismiss-all
(a caller that cannot show some registered agent) keeps that agent's
offers, clears only its audience's unwritten witnesses, and writes no
fence; a late write from this process is serialized behind it. The field
never left this unreleased branch.

* fix(agent-session): refuse an attach whose agent is not the session's own

The start check judges the record's agent while the router starts the adapter of params.agent, and the attach wire let the two differ. Admission now refuses agent !== provider as requestMalformed, so the agent checked is the agent started. Every host-built attach already sets them equal.

* fix(agent-session): offer to start a chat only when the start would accept it

The restart offer, a failure's retryable flag and the pre-send check asked only whether the adapter runs the chat's location, while the start also refuses a record this build cannot drive; such a chat was offered Resume and its Retry failed forever. One host predicate, hostCanStartRecord (location support and agentDrivesSession), now answers all four; adapterSupportsRecord stays the reader gate, and an undrivable chat's offer is kept, not retired.

* fix(agent-session): the model-catalog probe uses a record's account only if this build drives it

A record-scoped catalog read started the agent's lister under the record's account path whatever variable the record pinned. It now uses that path only when agentDrivesSession holds, and otherwise resolves the account as for a read with no record.

* refactor(agent-session): the record store admits agent ids; comments say where transport is checked

The store only ever asked whether an agent is registered, so its admission list is now the registered ids; the definition is the one home of an agent's transport and account variable. Comments that said the record store checks transport, and one that cited a nonexistent function, now point at agentDrivesSession and the attach admission. The isPersistedAgentSessionRecord(value, agents) call shape and the test fixture the cross-version probe imports are kept.

* docs(agent-session): the record store admits the registered agents' ids

* refactor(native-chat): Grok's registration declares where it runs; ACP no longer borrows Codex's location rule

The rule a self-supervised agent child runs under (this machine, no WSL, Windows only with process
start-time proof) is its own module that Codex and the ACP adapter both use. Grok's registration
takes the full account-home resolver signature, and D3's tests build hosts with the agent registry.

* fix(native-chat): Grok follows the ACP runtime's request contract and the managed process's close

A request the agent or a Stop cancels is answered with the agent's own cancelled reply by the code that
owns it (the runtime no longer answers a silent handler), so a Stop needs no separate decline pass. A
permission answer still being saved when the agent stopped waiting is reported unconfirmed, since the
protocol already answered it cancelled. Cancelling the agent's own turn is the plain cancel. Request
rows are matched under their generation-scoped ids. A refusal's reason comes from the dialect's wording
path. The child drops its own stderr tail and close policy for the managed process's, and a close
whose process tree was not proven gone is reported as the adapter contract asks.

* fix(native-chat): a Grok chat Orca already holds resumes without writing what Grok replays

A chat with a saved Grok session reattaches with session/resume where the agent offers it, else
session/load. Either way the call runs inside the translator's load window, so what Grok sends while
it reattaches (its saved exchange, a task the dead process left running, ended by the restart) opens
no turn and writes no row; only context usage reads on. A reply an Orca or Grok crash cut short is no
longer completed from Grok's saved history: it reads like a Claude or Codex chat's, with the existing
notice. The attach window also closes after a failed attach, and a created session that session/resume
reports missing is replaced like one session/load reports missing.

The replay reconciliation is removed: the lane no longer reads the journal, and D3's replayed-input
grammar test and completed-turn check in the assembler go with it.

* refactor(native-chat): a failed Grok reattach needs no window close of its own; its lane is replaced

* test(native-chat): D3's merged tests use the shipped declarations and the launch options main requires

* fix(native-chat): typecheck fallout of the base merges; any agent's empty chat is reusable

Main's idle-empty-chat lookup and launch join now take any registered agent, as the rest of the
launch path does. The refusal check moved into the prompt turns and the prompt-block conversion beside
the turns that send it, keeping both files in their line limit.

* fix(native-chat): a Grok Stop ends the process once Grok settles its turn; the next send resumes

Grok's session/cancel ends only the running turn: work it already moved to the background keeps
running and can begin a turn of its own after the person pressed Stop. Stop is now a session
boundary, as it is for Claude: the cancel answers open requests and lets Grok end the turn, the host
waits a bounded grace for that, then ends the process; the next send relaunches and resumes.
The adapter's own bounded close of a turn Grok began is gone. Its named-turn check stays: the host
ends the session unless the provider declines a Stop naming a turn that has since ended.

* test(native-chat): a Grok Stop ends the process only after Grok answered the cancel

* fix(native-chat): Steer on a Grok card cancels the running prompt, then sends it

A send that reached Grok while a prompt ran was held in the adapter until that turn ended: Steer
on a queued card took the card out of the host's editable queue and meant 'send after this turn'.
It now cancels the running prompt (session/cancel; the session stays) and sends as the next prompt
once Grok answers the cancel, as the common pattern does; a steer behind another cancels it in
turn, so the last one runs. The adapter holds a send only while that cancel lands, so its general
held-send queue and its holdsDispatch report are gone (every send it holds has its turn open in
the journal). An older client's mid-turn send takes the same path. capabilities.steering is
unchanged and still unread.

* refactor(native-chat): a close or Stop cancels a start through the acquire's own abort signal

The host owns the acquire it runs, so it now owns its cancellation: each attach's acquire gets an
AbortSignal, aborted from outside the session's queue by a close and by a Stop admitted now (the
same admission rule as before). The optional abandonStart adapter hook, the router's fan-out to
every adapter and the ACP adapter's session-keyed start map are gone; the ACP adapter keeps an
unkeyed set of starts only so quit can prove their children gone, and keeps a failed start's
unproven child until its exit is proven.
The hook also let a later close ask that child again. The host now does that from state it holds:
a close of a chat with no live child whose record still names an owner process with no death
evidence asks the adapter to release it. The answer is not recorded as proof (the lease probe
does that), so an owner pid an earlier Orca left is never killed or marked gone. Claude and Codex
ignore the signal and hold no such child; their release is a no-op (tested).

* fix(native-chat): a Grok crash that closes stdout before its exit still ends with Grok's last words

On macOS and Linux the agent's stdout ends before its exit is observed, with or without the
supervisor's EOF forwarding, so the connection's loss closed the journal first and its error text
became the session's ended reason, dropping Grok's stderr. The reason is now read at the proven
exit: the agent's last words when it left any, else why the connection closed. The failure already
carried them. Comments that assumed the exit comes first, that early frames past the cap refuse the
start, and that dispatch re-checks image support are corrected.

* fix(native-chat): nothing Grok sends while a held chat reattaches is written, marked as replay or not

The reattach window relied on the dialect's replay verdict, and Grok's frames read as live unless
they carry isReplay, so an unmarked chat frame during session/resume opened a turn that never
ended. D3 now marks every frame inside the window as replay before the translator reads it, so the
translator keeps only context usage whatever the agent marked; options and commands are still
adopted. The translator's load semantics are unchanged.

* test(native-chat): a Stop after a resume finds no turn an unmarked old reply opened

* test(native-chat): a resumed Grok chat keeps its last context reading; the resume refreshes only the window

* test(native-chat): a Grok background task a Stop ended reads as stopped reporting

* refactor(native-chat): quit's stop of each start answers through one promise kind

* fix(native-chat): quit aborts every start the host has in flight before draining attaches

A Grok that never answered its handshake held quit until the start's own 60 s bound, past the
20 s quit deadline. The host's teardown now aborts each in-flight acquire (and any the drain
still begins), so the adapter's own quit controller and its map of starts are gone: a start
has one canceller, the host's signal.

* fix(native-chat): a Grok start's abort stops reaching its child once the start has returned

The listener stayed on the host's signal until the attach finished committing, so a Close in that
window killed the now-live child behind the host's back and it read as Grok crashing. The start
now detaches it when it ends; a later Close goes through the session's own stop.

* fix(native-chat): a close or Stop during any attach phase stops the start before it launches

The attach began its abort controller only after reconciling leases, resolving recovery and
probing the previous owner, so a close or admitted Stop in those phases reached nothing and Grok
launched anyway. The controller now begins first, and the acquisition checks it before asking the
adapter to start.

* test(native-chat): a close during the attach's owner probe asks no adapter to start

Also renames the close test after the hook it no longer exercises.

* test(native-chat): a close's re-ask closes a Claude or Codex child a failed cleanup left

The re-ask is not a no-op for them: when the adapter still holds the child its cleanup could not
prove gone, the close stops it again as a requested close, and Claude persists the handle of the
conversation it ran so the next send resumes it. Corrects the tests' and comment's wording; the
close awaits the re-ask, bounded by each adapter's kill ladder.

* fix(native-chat): Steer during a turn Grok began itself cancels it and sends once it ends

A send while Grok ran a turn of its own (a background task waking it) went straight to Grok, which
queued it behind that turn where Orca could no longer withdraw it, while Stop treated the same turn
as the running reply. The send now waits as a steer, the turn is cancelled once, and the message
goes when the turn ends; a Stop withdraws it and an exit rejects it as never sent.

* test(native-chat): a steer whose cancel Grok never answers ends Grok and is rejected as never sent

Pins the bounded steer cancel kept from the runtime: past the bound the connection closes, the
running reply reads unverifiable, Grok's end reads as its exit, and the waiting steer is rejected
as never sent.

* fix(native-chat): a Grok crash stays a crash when a stop lands before its exit is proven

After the connection broke and the close could not prove Grok's exit, any later stop Orca asked
for (the next start, a Stop, a Close) marked the child as closed by Orca, so the crash read as a
requested close and Grok's last words were dropped; a send meanwhile was recorded unconfirmed.
The connection loss now decides the cause, and a send on that session is rejected as never sent.

* test(native-chat): fixtures this PR's registered Grok and desktop capability made stale

CI's unit shards failed on tests outside the PR's own lists. Each encodes something this PR changes
on purpose: Grok is now a registered agent (the seam test's unregistered agent is now Cursor); the
desktop now advertises registered agents (the restart-offer tests' older client drops that
capability explicitly); the attach context carries the start's abort controllers (the forget-status
double gains them); and the ACP real-host test rig sends to the host directly (listed beside the
other real-host rig in the send ratchet).

* fix(native-chat): a start quit stops is not the queued message's start failure

With quit now aborting a start it would have waited for, the delivery step recorded the aborted
start as the message's failure ("couldn't restart"). After quit has stopped delivery, the step
leaves the message to quit, which settles it as a close does ("The chat closed before this message
was sent."). The test that pinned quit waiting for that start and stopping its child now pins that
nothing is launched behind quit.

* fix(native-chat): a message sent after a Stop or close aborted a start gets its own start

A start the host aborts (an admitted Stop, a close, or quit) returned its refusal to the delivery
loop, which then rejected whatever was queued at that moment with "couldn't restart", including a
message the user sent after the Stop. The attach now reports that the host aborted it, and the loop
re-derives from the journal instead: what the Stop or close withdrew is already settled, a message
accepted since gets a start of its own, and quit's next step stops the loop. This replaces the
quit-only carve-out with the same rule for every abort and every agent.

* test(native-chat): the message sent after an aborted start is answered, so no settlement outlives the test

* fix(native-chat): a Grok model pick Grok never answers no longer holds Stop or Close

The pick runs on the session's queue. It now registers in the host's out-of-queue
abort registry beside a start, so a close, an admitted Stop or quit abandons it, and
the ACP adapter bounds it at 30 s like Claude and Codex. A late answer is still adopted.

* fix(agent-launch): a phone's launch opens a terminal for an agent whose chat it cannot show

agent.launch now reads the caller's capabilities by the rule tabs and restart offers
use (clientRendersStructuredAgent). A phone without registered-agents.v1 gets Grok as
a terminal again, as on main; the host's own callers and desktop clients are unchanged.

* fix(acp): strip every agent hook variable from the ACP child, from the shared list

ACP_CHILD_ENV_TO_DELETE was a second copy of the hook runtime keys that missed
ORCA_AGENT_HOOK_TRANSPORT; it now spreads AGENT_HOOK_RUNTIME_ENV_KEYS beside the pane
identity keys.

* refactor(native-chat): the mutation context carries the provider-wait registry itself

Keeps the host file within its line limit; one field instead of two closures over it.

* fix(agent-launch): agent.launch.v2 still vouches for Claude and Codex chats

The caller rule from the previous commit also turned Claude and Codex into terminals
for a client advertising only agent.launch.v2, whose contract says it opens a chat
(mobile retry-authority tests). Only an agent beyond those two now needs the client to
read it (clientRendersStructuredAgent); the test fixtures go back to what they were.

* refactor(native-chat): drop saved-history adoption from the timeline assembler

The common pattern discards the history a provider replays while loading a
session, so the assembler has no use for an input.history event.

* refactor(acp): drop session/load history adoption from the translator

The common pattern discards the history an agent replays during session/load,
keeping only what it says about the context window. Remove the adoption path
(acp-history-adoption.ts, the adopt option, and the historical background-task
liveness rewrite it fed) so load replay is always dropped except usage.

* refactor(native-chat): a pending input is only Orca's send now

Review follow-up to the adoption removal: drop the comment naming the
provider's saved message, and make requestedAt required since every pending
input comes from input.accepted.

* test(acp): keep the task-result status table on live frames

Review follow-up to the adoption removal: the result-status mapping was only
tested through adopted history, so run the same table on live frames, and
cover an unmarked task notice during a load being dropped.

* test(acp): a frame helper for a shell command Grok is running

* fix(acp): a Grok crash settles through the host's provider-exit batch, scoped to the turn it ended

A Grok crash ended the journal unverifiable before the adapter reported the exit, so the host's
provider-exit settlement found no running turn and wrote nothing: the adapter's failure (with
Grok's last words) never reached the journal, and a later stale-session pass wrote a bare,
thread-scoped cut-short row, so the partial reply was not folded as Claude's and Codex's are.

At a proven exit the ACP lane now ends its running turn interrupted at the exit instant, as the
host's exit contract expects of a child's own translator (Codex's does the same). When Grok's
stdout closed first (every POSIX crash), the turn is unverifiable only until the exit is proven:
the host's provider-exit settlement now takes the exit as proof naming the child's fence and
revises what that child left unverifiable in the same batch, with the turn-scoped row and the
adapter's failure. Claude and Codex write no unverifiable turn of a live child except a command
whose hand-off is in doubt; that turn is now revised at the exit instead of at the next open.

* test(acp): a crash seen first leaves the host no Grok turn to revise

* refactor(native-chat): what a gone generation left unfinished gets its own module

The settlement file passed 300 lines with the exit-proof revision. The unfinished-work reads
(capture, interrupted-by-the-exit, in-progress) are their own concept and move out unchanged,
apart from the exit proof they now take.

* refactor(native-chat): a watched exit revises what its child left unverifiable without reading Stop marks

An exit's own instant is the turn's end, so the revision needs only each row's fence: the
settlement's journal type gains itemFence alone, and the host test fakes say so.

* test(native-chat): drop the duplicate itemFence on the fake that already had one

* test(claude, codex): an exit whose stdout ended first still reports as it always did

The provider supervisor now ends Orca's stdout when the agent's ends, so on every crash EOF
arrives before the exit is seen. Claude's and Codex's connections report nothing at EOF and
report the exit, with its usual reason, once it is seen.

* fix(acp): reopen a chat with session/load, as the common pattern does

An agent that offers both now reloads its session instead of resuming it; the
reattach window still discards what it replays except context usage.

* fix(acp): drop the 60 s handshake bound; an abort fails the start's waits at once

Neither common design bounds an ACP handshake: Close, Stop and quit end a start
that never answers. The abort now also closes the connection, as a kill there
does, so the start settles even before the child's exit is proven. The
host-stopped start refusal only this bound produced goes with it; the idle
sweep keeps its words.

* fix(acp): a Stop naming an ended turn follows Claude's rule

It still stops nothing while another turn is live, but in the gap before a
follow-up's turn opens, which no client can name, it now stops what is in
flight and the session ends, as a Claude Stop does.

* fix(native-chat): a close no longer re-asks a failed start's unproven child

Neither common design retries that stop at Close, and Orca's Claude contract
re-asks only at the next start and at quit. The ACP adapter keeps the child
until its exit is proven and asks it again there, as Claude does.

* fix(acp): a message sent during a turn the agent began itself goes at once

Both common designs send it straight to the agent with no cancel; only Orca's
own running prompt is steered (cancelled, then re-prompted).

* test(native-chat): dismiss-all through a remote client's audience keeps a newer Orca's offer

Uses an audience production sends (one that cannot show every agent), per review.

* fix(acp): launch Grok as `grok agent stdio`, without the update and leader flags

The common pattern passes neither --no-auto-update, --no-leader nor
GROK_DISABLE_AUTOUPDATER; full access still adds --always-approve.

* fix(acp): an agent that ends its stdout, or answers unreadably, is not a lost connection

As in the common pattern, only a broken stdin (or Orca's own close) ends the
agent; one that closed its output but can still be written to stays until a
Stop, a close or its exit. The provider supervisor goes back to its base
content, so Claude and Codex no longer get the forwarded stdout end either.

* fix(native-chat): a person's close joining a failed one still binds the turn its child end cuts

On main every close of the chat writes its own Stop and settle. Here a later close joins the
first and writes no row, and the first's settle closed when its kill failed, so a turn that opened
in between and was cut by the next close read as failed. A person's close joining a person's close
whose Stop opened a settle now reopens that settle until its attempt is done.

Tests: a close whose kill failed still closes its settle; a turn opened between a failed close and
the next reads as the person's cancellation (each fails without its half of the fix).

* test(native-chat): Grok opens as a chat only behind the structured-chat setting

agent.launch and orchestration worker-start read the same setting as the
renderer route; pin both states for Grok on each. The setting's description no
longer names only Codex and Claude, in every catalog.

* docs(acp): generic ACP comments say what holds for every agent, not Grok

Stop ends the session for every ACP agent, as in the common pattern; the
adoption hook comment goes (adoption is not planned); a failed start's child is
retried at the next start or quit.

* test(claude, codex): type the EOF-before-exit test's streams; the supervisor no longer forwards EOF

The Claude test wrote to the child's stdout and stderr through their Readable
type, which the node typecheck rejects; it now holds its own PassThrough
streams. The comments no longer credit the reverted supervisor change.

* feat(acp): a steer's cancel asks once and never ends the agent

The runtime had one cancel: send session/cancel, wait at most 10 s for Orca's prompt to settle,
then close the connection, which ends the agent. A steer used it too, so a slow agent lost its
process just because the person added a message. requestSteerCancel() now sends session/cancel
once per prompt, cancels the agent's open requests and answers later permissions cancelled, and
never bounds or closes: the prompt's own reply ends it and the steer's prompt follows. cancel()
stays the Stop: bounded, then close. A Stop after a steer still bounds and closes. Both cancel
paths move into acp-prompt-cancel.ts over one cancel channel.

* chore(native-chat): keep the record store and recovery capsule under max-lines after the main merge

* fix(acp): a repeated steer shares the cancel in flight; say what the caller owns

Per review: a second steer before the first write lands returns that write instead of resolving
early. The steer's JSDoc says the wait for the prompt's reply is unbounded and that a prompt that
fails instead must not take the steer until the caller rebuilds the session; the Stop's says a
prompt that settles in time leaves the agent for the Stop's owner to end. The steer test now gives
the runtime a handler that would allow: the open permission's signal aborts and the late one never
reaches it.

* fix(native-chat): drop the stopDelivery the A3 merge doubled

* fix(acp): a steer's cancel asks Grok once and never ends it

A steer now uses D1's notify-only cancel. Two messages sent during a reply Grok began itself
cut that reply, as the common pattern does, and then both run; before, the queued first
message could not answer the bounded cancel and Orca ended Grok although Grok answered.
A Stop keeps the bounded cancel and its 4 s grace.

* fix(acp): a permission Grok asks with no prompt of Orca's running is declined

During a turn Grok began itself nobody asked it to act, so the request is answered
cancelled at once instead of opening a card that waits, as the common pattern does.

* fix(acp): a Grok that dies while starting is reported with its own last words

A dying process's stdout ends before its exit is seen, so the start failed as a closed
connection and Grok's stderr was lost. A start whose connection closed now waits, bounded by
the Stop grace (or a Close/Stop), for the exit before it is told.

* test: a Stop after a steer sends its own cancel; drop the import the A3 merge doubled

* test(native-chat): main's Stop-note test builds its turn context with the agent registry

* test(claude): say why the close test's fake child cast is safe

* test(native-chat): build the Stop-opened-turn test's identity and turn context the current way

The test (#25056) landed before the opaque provider handle (#24991), so main still built
the old {kind, threadId} handle; the turn context also needs this branch's agent registry.

* test(native-chat): build the Stop-opened-turn test's identity with the opaque handle

The test (#25056) landed before the opaque provider handle (#24991), so main still built
the old {kind, threadId} handle.

* test(ratchet): require src/main/provider-process now that it has landed

* test(native-chat): keep main's opaque-handle import in the Stop-opened-turn test

Main's #25706 and this branch both added the import at different lines; the merge kept both.

* test(native-chat): keep main's opaque-handle import in the Stop-opened-turn test

Main's #25706 made the same fix as this branch at a different line; the merge kept both imports.

* feat(native-chat): record a fresh provider conversation that replaced one the agent could not restore

A chat whose saved conversation the agent cannot reopen can now continue in a
fresh one: the handle chain records the new conversation as a creation that
replaces the lost one (which, why, and when), keeping every earlier link.

Rows keep a shape older builds read: the stored chain starts at the latest
replacement and carries the earlier links inside it.

* test(native-chat): build this stack's journal identities with main's opaque provider handle

Main's #24991 replaced the {kind, ...} handle with {transport, agent, nativeId}; three test
files from this stack still wrote the old shape. Same lines the downstream ACP branch uses.

* docs(acp): every reattach drops the agent's replay, not only for a chat the journal holds

* refactor(native-chat): store a replaced conversation flat; refuse it where older builds read the row

Older builds only read Claude and Codex records, so the nested stored form
protected rows no replacement can reach while adding a cap mismatch after a
downgrade. Store the chain as held, refuse a replacement in a Claude or Codex
chain until one has a stored shape older builds read, and refuse a supersession
key on a replacement that names no creation in the chain.

* refactor(native-chat): read hosts' structured agents from the app-shell services

Main grew the startup hydration hook to its line limit; the host agents sync is an app-lifetime subscription like the structured session tabs sync beside it, so it moves there.

* Use current provider handles in transition tests

* Use current provider handles in timeline fixtures

* test(native-chat): prove replacement rows survive downgrade and re-upgrade

* Require the ACP directory in the runtime import check

* test(ratchet): require src/main/acp now that this PR lands it

* feat(acp): a saved session the agent cannot reopen continues in a new one, with one warning row

When session/load (or session/resume) of a saved ACP session fails, the chat starts a new session and records it as a creation that replaces the lost one (#25747's 'replaces' link), and writes one warning row that the agent no longer remembers the earlier messages. A created session the agent reports missing is still superseded silently; a signed-out agent or a start that is over (Close, Stop, a lost agent) still fails the start.

* chore(acp): rewrap the acquire header comment

* test(acp): a start closed while the agent reopens fails without opening or announcing a new session

* Let ACP connections own their supervised agent process

* Preserve ACP cleanup evidence and isolate exit observers

* Expose ACP cleanup observations and type the permission fixture

* refactor(native-chat): the registered-agents capability lives in its own module

Main's growth put protocol-version.ts one counted line over its 300-line limit once the capability
was added; like main's other per-feature capabilities, it now has its own module, and importers read
it from there.

* refactor(acp): one connection owns the Grok process and its protocol

D3 now opens each ACP agent through createAcpAgentConnection (ACP-ALIGN #25810): one object spawns the
process on the execution host, owns its stdio and protocol, and reports its proven exit. It is built and
tracked before the handshake, so a start's abort (Close, Stop, quit) still reaches it, and a failed start
keeps that same connection for the next close to retry rather than spawning another process.

Deleted: the spawnAcpStructuredChild wrapper and its test, the raw-stream runtime assembly, the caller's
exit -> runtime.close wiring, the stdout-EOF heuristic (the connection no longer treats stdout EOF as
exit), and the 10 s steer/Stop cancel bound with requestSteerCancel. Reader control maps to
pauseReading/resumeReading; a close is connection.close after the host's existing 4 s Stop grace.

The adapter owns what the protocol no longer does: one session/cancel per running prompt however many
steers arrive (cleared with that send's settlement, retried after a failed write), and a Stop or steer
answers every open agent request the person has not already answered with the agent's own cancelled
reply. An answer already being saved when the Stop lands is sent.

Tests: blocked cancel write never holds Stop's grace, two quick steers send one cancel, a failed cancel
write is retried, a real process exiting while a child holds its stdout ends the session, and the
existing start-abort, retention, crash, connection-loss and reload-failure suites on the new rig.

* fix(acp): Grok signs in on its own machine with its API key or cached sign-in

When Grok reports that it needs authentication, Orca now names a sign-in method on the machine Grok runs
on, read from the same environment Grok was launched with: xai.api_key when XAI_API_KEY is set there and
Grok offers that method, else cached_token when Grok offers it, else none and the chat keeps the existing
not-signed-in refusal. The rule lives in Grok's launch spec; the adapter applies any agent's rule for new
and reopened sessions through the protocol client's caller-named method (authenticate, then retry once).
No new sign-in UI; interactive methods are never chosen.

* fix(acp): the adapter decides which of Grok's requests reach the person

The turn owner now admits every agent request, permission or question, from its own turn state: a
request reaches the person only while Orca's prompt runs and no steer or Stop is cutting it short (a
question may also come from a turn Grok began itself, until a Stop). Anything else gets the agent's
own cancelled reply and opens no card, so a question arriving after Stop or during a steer never
appears. A steer, like a Stop, withdraws the requests already open; an answer already being saved is
still sent. The protocol client's abort-on-cancel path is no longer used: after the connection
change its request signal aborts only when the connection closes.

* fix(acp): a plan Grok proposes shows as a plan, with no approval card

When Grok leaves plan mode it asks the client to approve its plan (x.ai/exit_plan_mode). Orca showed a
blocking 'Approve plan / Request changes' card for it; the common pattern has no such gate. Now the
plan goes into the chat's existing Plan row (the plan-document status row Codex and ACP plan updates
already use) and the request is answered at once with 'abandoned' plus feedback telling Grok to stop and
wait for the person's feedback or a request to implement it in a later turn, so nothing is approved on
the person's behalf. Dialects gain settleRequest for requests answered without asking anyone.

* fix(orchestration): worker-start opens a Grok worker in a terminal, as before

With the structured chat setting on, worker-start decided 'structured' for Grok and then the structured
worker factory (Claude and Codex only) refused it, so the start failed; main opened a terminal Grok
worker. Worker-start now decides with no registered agents beyond Claude and Codex, so Grok gets a
terminal worker as before. agent.launch and the app's own launches still open Grok as a structured
chat. Temporary until structured workers take registered agents.

* fix(acp): a prompt answer Orca can't read ends the turn instead of hanging it

A session/prompt rejection that was not the agent's own error answer (an answer that fails Orca's
schema, or one too large to read) left the turn running: the next message became a steer with nothing
to cancel and was never sent or settled, and Stop waited its full grace. As in the common pattern, any
prompt failure now ends the turn as failed (a failed-turn row without words, since none are the
agent's) and settles the send, so the next message goes. Only a closed connection keeps the send
running, for the connection-loss path to settle.

* fix(acp): send Grok's prompt-identity extension only to agents that echo it

session/prompt carried _meta {promptId, requestId} for every ACP agent, though only Grok's dialect
echoes it (injectedPromptIdentity). Now only an agent whose dialect declares it gets the extension;
other ACP agents get a plain prompt.

* refactor(native-chat): the registered-agents capability lives in protocol-version again, as on main

This reverts 0ef6d21815. That commit moved the capability to its own module only because main's
protocol-version.ts was then one counted line over its limit; main now defines it there itself within
the limit, and main's new restart test imports it from there. Main's test also reads the desktop's
capability list as an older client; on this branch the desktop advertises registered agents, so its
older client is that list without this one capability.

* test(acp): read the sign-in method with a schema, not a type assertion

* refactor(native-chat): composer transport and Stop control in their own modules

Main's rewind change (#19338) brought NativeChatStructuredSession.tsx and use-structured-agent-session.ts
to their line limits, leaving no room for this branch's image-acceptance and unpublished-Stop lines.
The composer's transport (sends, commands, options, image acceptance) moves to
use-native-chat-structured-composer-transport.ts, and whether Stop shows and what it does moves to
structured-agent-session-stop-control.ts. Behavior is unchanged; the runtime cast on the composer's
'local' | 'remote' is now a typed return.

* test(native-chat): read registered agents by id, as main's structuredAgentsReadBy now takes

Main's A3 squash changed structuredAgentsReadBy to take agent ids; this branch's test still passed
{ agent } objects (CI typecheck TS2322).

* fix(acp): a first reopen warns when Grok forgets a chat that exchanged turns

A Grok session the chat created was treated as one Grok never saved, so
when Grok reported it missing on the chat's first reopen, Orca swapped in
a fresh session silently, even after completed exchanges: the person saw
the old messages while Grok had forgotten them.

The launch now counts a created session as never saved only when the
chat's journal, read at the failed reopen, holds no turn of that Grok
session; anything else, an unreadable journal included, takes the normal
path: the fresh session is recorded as replacing the old one and the one
warning row is written.

* fix(acp): a start writes the warning row an earlier attach failure dropped

The row saying Grok forgot the chat was written only into the attach's
deferred sink, while the fresh session's link was saved earlier. An attach
failure, quit or crash in between dropped the row forever.

Every start now derives the owed rows: each conversation the chain says was
lost to a failed restore gets its row unless the chat's journal already holds
it. The row now names the lost conversation rather than the fresh session, so
a row an unused replacement wrote still counts after Grok supersedes it.

* fix(acp): a question during a turn the agent began itself gets its cancelled reply

A question or other card-opening request the agent sends while no prompt of
Orca's runs (a turn it began itself, as when a background task wakes it) now
gets the agent's own cancelled reply and opens no card, the same rule
permissions already follow there. Nobody is waiting on that turn. A plan the
agent shares in it is still shown.

* test(native-chat): import the unfinished-work capture from the module that owns it

Main's reasoning sweep test (#19221) imported it from the dead-generation settlement, which
this branch split it out of.

* refactor(native-chat): keep the session host within its line budget after main's Stop work

Main's #25949 left the host at exactly its 300-line budget, and this branch's acquire-abort wiring
adds one line. The reveal module now comes in as a namespace import, as the host already does for
its other helper modules, and the earlier reorder of two type imports is undone.

* test(codex): move the stdout-before-exit test into its own file

Main's connection test file is at its 800-line test budget, and this branch's exit-order test
pushed it over (CI lint, max-lines).

* fix(acp): cancel a running turn before a close, dispose or quit ends the agent

Closing a tab, disposing a session or quitting while an ACP agent's turn ran
killed the process without asking the agent to cancel first. A requested
close now does what a Stop does: withdraw the agent's open requests and held
steers, send session/cancel once, and wait for the turn to end, bounded by
the Stop's grace (4 s), before closing the process. A close that follows a
Stop sends no second cancel and waits only what is left of that Stop's grace.
An idle close, a lost connection and a sink-failure force close are
unchanged. The cancel-and-wait moves to acp-structured-stop.ts, shared by
Stop and close.

* test(codex): pass resolveLaunchArgs in the stopped-send-order test so typecheck passes

Main's typecheck fails here too: #25721 made resolveLaunchArgs required and
this test (#25051) predates it. Same line, same place as the open main fix
(#25977), so merging main after it lands is a no-op.

* test(native-chat): run the close-aborts-start test on the Node runtime, as its SQLite journal fixture requires

* refactor(native-chat): the Stop control reads the outbox itself, so the chat hook stays within its line limit

* Keep the session host under the line cap after main's two new delegates

Pass the lifetime's conversation opener to reveal directly; it is already passed unbound to the mutation context.

Brennan Benson 0bdcaf36ed fix(claude): start a Claude chat with its saved options and send the first message at once (#25152)
* fix(claude): end a Claude start that never answers initialize after 120 s

* Read the Claude startup deadline inside startup; fix a stale test comment

* fix(claude): start a Claude chat on its initialize answer, not on a frame only a SessionStart hook sends

Startup waited for system/init or a SessionStart hook frame as well as the initialize answer.
Before the first turn only a SessionStart hook sends one, and Orca adds that hook only through
its optional status hooks, so with them off the first message was held forever. Startup now
lands on the initialize answer; a start frame already seen is still checked, and one naming
another session ends a started session. The deadline drops to 90 s so it fires inside the
host's 120 s start wait.

* fix(claude): time the Claude start by silence, and fail it at once on another session's frame

Claude answers initialize only after its SessionStart hooks finish, so a total-time deadline
would fail every start behind a slow hook. Each start frame now restarts the clock. A frame
naming another session fails a start still waiting on initialize at once, as before.

* test(claude): a real Claude chat starts and answers with every hook disabled

* Say what the start-frame re-arm covers, and check only start frames in the hook-less real test

* fix(native-chat): a Claude chat starts with its saved options and takes its first message at once

Saved model, effort, Fast and permission mode are passed as launch options, checked against the
account's cached model catalog, instead of restored by control requests after initialize. With
nothing left to restore, the host no longer holds a message until the CLI answers initialize, and
the 90 s startup deadline is gone. A Stop on a start that never answers ends the child and settles
what it was handed as stopped. A failed result that repeats the turn's own API error reply writes
no second row.

* fix(native-chat): a host stop of a Claude start fails the message it was handed, with one row

With no start-hold the delivery loop no longer sees a host stop of a start it waited on. The
child's end now rejects what it handed over with the host-stopped words and writes the one row,
as an exit of its own would; an idle start the host stops still goes quietly.

* test(native-chat): a Claude chat's first message is written before initialize answers

Rewrites the tests that encoded the start-hold, the startup deadline and the option restore to
the new contract, and adds: saved options at launch (catalog checks, bypass, fresh-session Fast),
a message written before initialize answers (adapter and runtime), Stop on a start that never
answers (stopped, child closed, nothing working), and an API error said once.

* revert(native-chat): keep a failed Claude turn's error row

The shared turn fold already shows a failed turn's error once after it settles, as an error;
dropping the row left the CLI's synthetic reply looking like something Claude said.

* fix(native-chat): pass saved Claude options unchecked, heal a retired model on the CLI's word, and never leave an unrun message in doubt

- Saved model, effort and Fast are launched as picked; only values no Claude can parse are left
  out. The pre-spawn cache check is gone.
- A saved Fast on for a new conversation is applied once the settings readback shows no
  per-session opt-in (dropped when there is one, or when the model is listed without Fast), with
  nothing waiting on it; the record keeps the pick.
- Under an Agent Permissions bypass, a saved narrower mode launches with the allow flag so bypass
  stays reachable.
- A turn whose reply is the CLI's model_not_found for the launched model drops that model from
  the record; the launch's own row for it is kept out of the account model cache.
- A child that ends before it answered initialize, for any reason, settles every message it was
  handed as not sent (cancelled for a Stop).
- A launched effort the CLI reports only as `applied.effort` is confirmed from there.
- The untimed-initialize comment is back to main's text.
- A real-CLI test for a message written before initialize answers, under saved options.

* fix(native-chat): type the close's ended event and the start-exit test fixtures

The close's ended event is typed as the adapter event so its optional startupUnanswered spread
fits exactOptionalPropertyTypes; two tests guard the fixture's optional generation, and the
hung-start fixture records initialize on the fake connection it holds.

* fix(native-chat): a Claude model heal keeps a later pick, a refused Fast is dropped, no allow flag

- `options-skipped` carries the retired value; the record drops it only while it still holds it.
- `started` carries the values a heal retired, and the record does not take them back from the
  CLI's report of the same value.
- A saved Fast on a new conversation is applied before `started`: a refusal drops it and records
  it skipped, as main's refused restore did; silence keeps it wanted and unconfirmed.
- A saved narrower mode under an Agent Permissions bypass launches without any bypass flag again:
  the allow flag is one older CLIs reject at start. Kept as a known limit.
- The real-CLI test asserts the message was written before initialize answered.
- The fake reports a launch effort only under `applied`, and a misplaced doc comment moves back.

* fix(native-chat): a new Claude chat reports started before its saved Fast is applied

The Fast apply on a new conversation now runs after `started`, so a Stop interrupts a running
first turn and an option write is not refused while the round trip is out. A refusal drops the
pick through `options-skipped`, in order after `started`; silence keeps it unconfirmed. The
launch's unreachable skipped-model branch is gone.

* fix(native-chat): a healed Claude chat goes back to the default model live; comments match the no-hold design

When the CLI says the launched model does not exist, the live child is also put back on the CLI's
own default (set_model with no model, fire-and-forget), so later messages in the same chat run; a
user's pick sent after it wins, and a refused or unanswered reset only logs. Comments that still
described the start-hold or the option restore now describe the launch options and the
handed-over, never-echoed rule.

* fix(native-chat): a message handed to a Claude start that never answered is kept as main keeps an unsent one

A child that ended before it answered initialize ran nothing it was handed, the same fact as a
send accepted and never handed over. Its end now settles those sends exactly as the chat settles
a queued send for that end: a quit keeps a person's message as a held card (restart words), a
close keeps it as a held card (closed words), a person's Stop withdraws it as cancelled, and a host
stop fails the start with one row.

* fix(native-chat): a quit during a Claude start that never answered offers no resume for the message it keeps as a card

The restart snapshot now reads the same never-answered fact the exit does, so a message handed
to such a start counts as queued work, not as work to resume. The retired-model reset comment
names the default it really applies.

* refactor(native-chat): the saved permission-mode launch helpers live with the spawn options that use them

Keeps claude-structured-launch-resolution.ts within max-lines once merged with main, and names
the hung-start test envelope's field type.

* fix(native-chat): a Claude chat's saved options take precedence over the agent Arguments' own flags

Main now passes the saved agent Arguments to the Claude child, and the SDK writes them after its
own options. An Arguments --model or --effort therefore reached the CLI as a second flag after the
chat's saved pick (a commander CLI keeps the last), and a saved Fast's launch settings replaced an
Arguments --settings file outright. The saved model and effort now stand in for the Arguments'
flags, and a saved Fast beside an Arguments --settings is applied by the start instead of at
launch.

* test(native-chat): the hand-built Claude session in the options test carries fastModeAtStart

* test(native-chat): the queued rig's start spy carries a named Mock type

An unannotated vi.fn() inferred @vitest/spy's internal Procedure, which CI's typecheck cannot
name in the factories' inferred return types (TS2883).

* fix(ci): run the PR's SQLite-backed tests in the Node runtime project

Lists the hung-start Stop test, renames the send-during-startup entry from its old name, and
carries main's own two entries from #26010 so the boundary test passes before the next merge.
