Brennan Benson ccb63afc06 fix(native-chat): a Stop still reads as yours after Orca restarts, because the turn's end reads the Stop's event (#24311)
* 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.

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

* 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.

Brennan Benson 0b79720c2e feat(native-chat): the chat strip and the sidebar read the host's child records (#22614)
* feat(native-chat): publish the host's child records to the status summary and the chat strip

The status summary and the background-task channel now read a session's child
records from the host's canonical store, through the status sink its row
landed in, and derive the legacy task and subagent shapes from the same views.
The parent row folds its child-work liveness from those records at ingest,
not from the summary's task list. The adapters no longer push their task DTO
to clients: the onBackgroundTasksChanged path is gone, and a child-work ingest
is what republishes both the summary and the strip. Finished children stay
listed until the session's own next turn starts. A reader that predates child
views never receives a roster whose rows are all settled.

* feat(native-chat): the chat strip reads the host's child records with its parent's verdict

The strip's roster now renders from the child views its channel carries, and
passes the verdict the session's own status row gives its children, built the
way the sidebar builds it (the row's freshness and the status feed's
observation). So one child reads the same in the strip and the sidebar, live,
after the transport drops, and once the row goes stale. A roster of finished
children stays shown until the next turn but no longer animates the monitoring
indicator or blocks conversation commands.

Tests: an end-to-end run on a host with no renderer (a real hook server as the
status sink) shows the summary and the strip channel carrying the same records
at every step, the parent row folded from them, retention, and an older
client's task list holding live work only; a wired renderer test shows both
surfaces agree when live, lost and stale.

* test(native-chat): a newer host's view degrades, an older reader keeps its live roster, a finished roster holds nothing open

- The view decoder ignores unknown keys, degrades unknown kinds, states,
  outcomes and memberships, and drops only rows it cannot identify.
- At the RPC boundary a reader that predates child views gets no strip for a
  roster of finished children and never the views themselves; a stop-only
  reader keeps rows whose host offers no targeted stop.
- The strip shows finished children without reading them as live work.
- The row keeps its child list's identity when a summary repeats it.

* refactor(native-chat): the summary's task list is the legacy projection's live rows, unfiltered

* test(native-chat): type the switch tests' mocks instead of asserting them

* test: remote clients advertise reading child views

* docs(agent-status): the structured row folds the store's child records

* fix(agent-status): keep the view reader's header from reading as a value import to the renderer boundary

The renderer node-builtin boundary test scans raw text, so a header comment
that said "imports" ahead of the import block turned the type-only import of
agent-status-child-work into a value edge that reaches node:crypto.

* refactor(native-chat): the status summary's broadcast equality gets its own module

The status feed crossed the file-size limit once the summary gained the main agent's turn
outcome beside the child views. Which summary changes reach every session list now lives in
structured-agent-session-status-summary-equality.ts.

* fix(native-chat): command admission reads the strip's child records

A conversation command was refused on the provider tracker's own roster
while the strip read the host's child records, so a drift between the two
rule sets could refuse /clear with a stop instruction the strip had no
button for. Admission now reads the same records through the same read as
the strip, uses the strip's liveness fold, and asks for a stop only when
the strip renders one. The adapter contract no longer exposes the tracker
roster, so no host decision can read it.

Also records when the legacy child shapes die, every earlier death of a
settled child, and the display-precision invariant behind the summary's
clock tolerance.

* refactor(native-chat): command admission takes only what it reads of a turn

* fix(native-chat): the session list drops a session's children when the store does

A session's end no longer removes its child records: a child still running
settles with an outcome nobody reported, and a finished one stays listed.
Records now leave only at the session's own next turn, at the cap on settled
records, or when the host lets go of the session and its row leaves the store.

The summary kept after the host lets go used to strip its children on close,
a rule of its own. It now re-reads them from the store when the row leaves,
through the same read every live summary uses, so the session list and the
chat strip list the same children at each step, including a forget with no
close. Closing only revokes ownership, as before the child records existed.

* test(native-chat): write the Codex frame script's parent row out step by step

Once every surface reads the child records, the provider tracker's roster is
no oracle: it and the records read the same child executions, so agreeing
with it cannot catch a defect in either. Each frame now states the child
liveness and the parent row it must fold to.

* fix(native-chat): the idle sweep and the restart snapshot read the host's child records

The idle sweep (keep an agent running while its subagents or commands run) and
the restart-resume snapshot (what a chat was doing when Orca stopped it) both
read the provider tracker's roster through the adapter interface, which no
longer carries it. Both now take the host's one child-record read, the same one
the status summary, the chat strip and command admission use.

The snapshot's working test also folded that roster through the shared fold's
old `backgroundTasks` input, which the fold no longer reads, so a settled lead
whose subagent was still running would have been offered nothing. It now hands
the fold the records.

* test(native-chat): the child-record tests follow the merged command lifecycle

A command is a live child record from its start and is removed, not settled,
when it stops, whatever Codex tagged it. The end-to-end switch now shows the
child's `npm test` as a live row beside its dev server, and both are gone once
they exit; only the finished subagent stays listed until the next turn. Letting
go of the session is its tab closing, since a closed conversation whose tab
remains keeps its row.

Command admission's finished row is a subagent, the one kind that settles, and
the failed-verdict row test admits its live subagent as a host record, the only
thing the row folds.

* refactor(native-chat): the status feed's journal projection cache gets its own module

The status feed crossed the file-size limit once the child records joined the
agent-start signal and the completion feed's status read. The per-journal
projection, cached per commit, now lives in
structured-agent-session-status-journal-projection.ts.

* test(native-chat): the admission test's compaction resolves with a real outcome

Main's compaction result is a tagged outcome; the host-level admission test
resolved its mock compaction with an empty object.

* feat(native-chat): the sidebar lists running subagents; the strip, running then the newest finished

The host keeps every child record; what each surface lists is picked from them on every read, so
nothing is stored twice. The status summary, which every session list reads, now carries only
running children (and a finished one whose shell still runs, which reads monitoring): a finished
or failed subagent leaves the sidebar and stays in the chat's strip. The strip lists every running
child, then the newest finished ones, 100 rows in all; more than 100 running all show.

This matches common practice: sidebars show live subagents, and finished ones stay in the chat's
panel, newest first. No wire field is added. An older client reads fewer rows: its legacy task
lists were already live-only in the summary, and the strip's settled tasks come from the same
bounded roster.

* fix(sidebar): one rule for what the worktree sidebar lists: running children, from every source

`worktreeSidebarListsChild` is the one definition: a child that runs, counting a finished one
whose own shell still runs (it reads monitoring). The sidebar's row builder applies it to every
child source it reads, a terminal agent's hook roster and a chat session's records alike, and the
host's status summary applies the same predicate, so the sidebar's payload stays small. The chat's
strip keeps finished children, newest first.

A terminal agent's hook roster already drops a child on its own stop, so nothing changes there:
a teammate between turns and a child gone quiet still run, and still show. The selection module
moves to `agent-child-work-listing.ts`, since it now covers every source, not only chat sessions.

* test(native-chat): the switch test passes the startup child key main's status bar takes

* fix(native-chat): a finished child stays until the user's next send, not a turn Claude opens on its own

Claude wakes the agent on its own when a background task ends, and that wake is a
new root turn. Keying retention on the newest root turn retired every finished
child about two seconds after a background agent or shell finished, so its
outcome never showed in the strip.

Retention now keys on the user's newest send the provider accepted (a message, a
steer or a command), with the journal epoch so a rewind still retires. A turn the
provider opens itself and a subagent's turn carry no send. Replayed captured wake
orders through the real adapter, hook server and status feed.

* fix(native-chat): a background Stop reaches the tasks the child records show

The strip draws a row's Stop, and /clear, /compact and rewind wait for background
work, from the host's child records, but the Claude adapter still resolved which
tasks a Stop reached from its own tracker's roster, and refused to stop at all
once that roster was empty. A task the records kept live after the roster dropped
it showed a Stop that sent nothing and blocked those commands until the chat tab
closed.

The host now resolves the provider ids a Stop sends from the records (the same
per-row rule the strip and admission use; every such row for stop-all), and the
adapter stops exactly those, with no tracker guard. An acknowledged stop ends the
record: a running task sends its own stopped frame first, and the CLI answers
success with no frame for a task it no longer knows. A refused stop leaves the
record live. No production code reads the tracker's roster any more.

* fix(native-chat): one rule for a finished child that still owns live work, at any depth

The listing kept a finished child whose work ran through any depth of ownership,
but retention at the user's next turn protected only the direct owner, so a
finished agent whose finished subagent still ran a shell was removed and that
subagent jumped to the top level. Both now read settledOwnersOfLiveWork.

* fix(native-chat): an older client sees a Codex child's shell as it did before views

Clients that predate child views read a flat task roster derived from the views.
It listed a Codex child agent's shell as an extra row beside the running agent,
then as a bare command once the agent finished. The derivation now hides a
running agent's commands and names a finished agent's as "<agent> — <command>",
as the Codex tracker did; the label rule moves to a shared module both use.

* fix(native-chat): the chat decodes a roster's child rows once, as the frame arrives

The client reducer compared raw wire rows, so a row shaped by a newer host could
throw there, and the strip decoded a new array on every render, which defeated its
grouped-rows memo while a turn streamed. Rows are now decoded where the frame
enters the reducer, an unchanged roster keeps its identity, and the strip's parent
context is rebuilt only when one of its values changes.

* fix(native-chat): the strip channel forgets a closed conversation's roster

It kept the last roster fingerprint of every conversation for the host's lifetime.
The conversation map now tells observers when one leaves it. Also corrects the
summary's children comment: it carries running children only.

* docs(native-chat): rewrap the retention comment

* fix(native-chat): a task's own ending replaces a Stop's, and a child finished after the user wrote stays

Two lifecycle gaps from the round-1 fixes.

A Stop acknowledged ahead of the task's own ending relabelled it. The SDK hands
Orca a control answer as soon as it reads it and queues other frames, so when a
task finished just as the user pressed Stop, the acknowledgement arrived before
the task's completion the CLI wrote first, and the task read "Stopped" with its
result lost. An acknowledged Stop now ends a record provisionally (outcome basis
`stop-acknowledged`); the task's own terminal frame replaces it, and nothing
replaces an ending the task reported itself.

A finished child still vanished with no new action from the user when the send
the provider took was written before the child finished: a steer Claude takes at
its next boundary, or a queued draft handed over at the end of the turn. The
user's next turn now carries when they acted (the send's written time, or the
draft's queued time, both on the host clock), and only children that finished at
or before it retire; a later one stays until the user's next send. A rewind
still retires every finished child.

Also: a Stop-all keeps stopping the remaining tasks after one request fails, then
reports the failure.

* fix(native-chat): the strip keeps one empty list for a roster that omits one

A roster with only running or only finished rows made a new empty array on every
render, so the strip regrouped its rows each time. One shared empty list keeps
its memo.

* fix(native-chat): a strip row whose owner the 100-row budget cut renders under the main agent

The budget can keep a finished child and cut its finished owner. The child still
named that owner, so it rendered nowhere. The selection now clears an owner it
did not keep, as the view contract says for an owner outside the projection.

* fix(native-chat): a stop-all that times out stops asking, and "no children" is sent once

A stop-all kept asking after a request timed out, so a Claude CLI that stopped
answering control requests cost one full deadline per task, while the chat's
sends, Stop and /compact waited behind it. A timeout now ends the loop; other
request failures still let the remaining tasks be stopped.

The chat strip channel never remembered that it had sent "no children", so
every change in a chat with none re-sent that frame to each subscriber. It now
remembers it, and forgets only when the conversation closes.

Also renames agent-child-work-stop.ts to agent-child-work-stop-targets.ts, which
says what it answers: the provider ids a background Stop reaches.

* fix(native-chat): the status feed reads a journal snapshot with no submissions, and e2e tests use the child-work reader

CI on dbd2439cd4 was red in three places:
- first-work-branch-rename and the agentSession.subscribeStatus RPC test feed the status feed a
  journal whose snapshot lists items only. The projection reads the user's newest accepted send
  from `snapshot.submissions`; it now tolerates their absence, as the status projection beside
  it already did.
- the cross-version downgrade test still passed `backgroundTasks` to the teardown's working
  marker, which now takes `childWork`.
- an e2e unit test still gave the status feed the removed `readBackgroundTasks` dependency
  (harmless at run time, a type error in the tests/ project).

* fix(native-chat): the chat strip lists running children only, by the sidebar's rule, and hides when none runs

A finished subagent's result is already in the transcript ("Ran N subagents ·
completed"), so the strip is for work that runs. It now lists exactly what the
sidebar lists, by one predicate (a running child, or a finished one whose own
shell still runs, which reads monitoring), and the host sends no roster once none
runs, so the strip hides.

Gone with it: the 100-row budget and the running-then-newest-finished
selection, the re-homing of a child whose owner the budget cut, and the RPC
gate's rule for a roster of finished rows only (no such roster exists now).
Older clients still get their derived task list, running work only.

Finished records still stay in the host's store until the user's next accepted
message: they refuse a late frame of their run, let a task's own ending replace
an acknowledged Stop's, and keep a running shell's owner. Dating that retention
by when the user wrote the message only kept finished rows visible longer, so it
is removed.

* fix(native-chat): the strip shows running work only from any host, and hides after a released session's last child

- A new app paired with an older host no longer shows that host's finished task
  rows: the strip lists running work only, whatever host sent it, and hides when
  an older host's roster has only finished rows left.
- A test for the path that hides the strip when a session's last running child
  settles after the provider let go of the session (Claude's release path): the
  channel sends `null` though no provider answers for the session any more.
- A test comment still described the strip keeping finished children.

Brennan BensonandClaude 24edf0f64b fix(agent-status): a turn a crash cut off reads Interrupted, an unproven end Couldn't confirm (#23467)
* refactor(native-chat): remove the unused terminal handoff

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

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

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

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

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

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* fix(native-chat): a request that failed reads as failed

A structured chat whose only message the agent's start refused read as a
green finish, and a cancelled structured turn did too: the host published a
verdict only for turn records, and structured rows carried no `interrupted`.

The host projection now reads the session's latest request: its turn's
outcome, or `failure` for a send the agent or its start refused. A send
that was withdrawn, or left undelivered by a restart or a close, fails
nobody and makes nothing listable. The ingest publishes `interrupted` as the
hook lanes do, and every reader decodes the verdict through one accessor, so
a failure reads Failed on the dot, the rollups, history and `worktree ps`,
behaves like a cancellation in every clean-finish policy, and notifies as
"failed".

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): a verdict change republishes the mobile status projection

* refactor(native-chat): the store's retention trigger keeps its flag compare

A verdict change always moves the completion clock the same check already
reads, so a second verdict compare there caught nothing new.

* test(native-chat): a user message the provider journaled keeps its session listed

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* fix(native-chat): a late provider-session update keeps a failed recovery record failed

A provider-session heartbeat that rewrites a completed recovery record kept
its interrupted flag but dropped the outcome it was copied with, so a live
failed checkpoint read as a clean finish until the next status write.

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* test(native-chat): the terminal-bell check asserts the renamed verdict field

The bell notification test still checked for agentInterrupted, which no
longer exists, so it could not catch a verdict leaking into a bell dispatch.

* fix(native-chat): a failed turn ranks like a completion for attention

Attention readers (completion time, Smart Sort, sticky retention, Cmd+J
Recent) now demote only a turn the user stopped. A failure is news the
user has not seen, so it keeps its completion time, ranks in the Done
class, stays retained after its pane goes away, and a retained failure
reads failed in the worktree rollup instead of done. Clean-finish
policy (hibernation, pane ownership, the value moment) still treats a
failure like a stop.

The retention trigger compares verdicts again: success -> failure no
longer moves the completion clock.

* fix(native-chat): a failed main agent reads failed while its subagents still work

The verdict is now read from the main agent's own state, not the folded
row: a main agent that is done and failed has a verdict even while its
subagents keep the row working. Without mainAgent (history, worktree ps,
older hosts) the old combined-done rule stands.

Display marks the verdict through agentVerdictDisplayMark: a failure
outranks every combined state on the agent's dot, label, tab badge,
dashboard and activity rows; a stop marks only a done row, so a
successful or stopped main agent with live subagents still reads
working. Subagent rows keep their own state. The worktree card, terminal
tab and Cmd+J rollups share one pane fold and rank a pending question,
then failed, then working, monitoring, interrupted and done.

worktree ps publishes the main agent's outcome on a working row, and the
mobile mirror reads it. The store's change check, the paired-client
mirror's equality and its epoch now see a verdict change on a working
row, which otherwise moves no state or clock and left the worktree card
reading working. Clean-finish policy is unchanged: a working row is never
hibernated and has no completion time.

* docs(native-chat): the worktree ps outcome comment no longer claims old hosts send it

The field is new: an old host sends no outcome at all, so a reader falls
back to interrupted. The removed clause said old hosts send it on done
rows, which never shipped.

* docs(native-chat): the status-store listing rule names provider-journaled user messages

* fix(native-chat): a refused send notifies failed through the completion feed

The host's completion feed followed only the newest turn, so a send the
agent or its start refused, which creates no turn, read Failed on its row
but sent no notification. The feed now follows the session's latest
request, read from the projection the status feed already makes for the
commit: a turn keeps its id, a refused send is named by its journal item
key. It announces only while the session is idle, as the row reports a
verdict, so queued sends refused one commit at a time notify once, and a
withdrawn send falls back to a request already announced.

* fix(native-chat): every copy of a row carries the main agent's own status

History entries, sleep records and `worktree ps` rows carried a flattened
top-level `outcome`, copied under different gates and without the main agent's
clock. They now carry `mainAgent` (state, outcome, stateStartedAt), the type
the live row already persists and sends, and every copy site takes it with
`interrupted` through one function, `agentVerdictFields`.

- The accessor reads `mainAgent` then the legacy flag; the mobile mirror
  matches it line for line.
- Sleep records admit `mainAgent` with `normalizeMainAgentStatusField`, so a
  malformed value drops the field, never the record.
- Mobile dates a main agent that failed under live subagents by its own clock,
  as desktop does, and its row equality compares `mainAgent`.
- The activity feed reads a history entry's own `mainAgent` instead of
  rebuilding one; the sync key and history equality compare it.

* test(native-chat): pin the worktree ps verdict across host and phone versions

Pairs the real v1.4.212 host and phone row reader with this build: an old phone
reads a new host's rows by `interrupted`, a new phone reads an old host's rows
(no `mainAgent`) the same way, and a new phone reads a failure under live
subagents as Failed, dated by `mainAgent.stateStartedAt`. The release checkout
now carries the phone's self-contained row reader, and the lane runs when the
`worktree ps` row producers change.

* test(mobile): name the parity table's row for its role

* fix(native-chat): a request that settles while the user is asked something notifies once

The completion edge waited for an idle session, and a pending prompt (including a
subagent's approval) is not idle. Structured chat has no other attention producer,
so a main turn that finished while a subagent waited on the user sent nothing
until the prompt was answered.

The edge now waits only on owed work (a running turn or an unanswered send), which
the projection reports even beneath a pending prompt. A request that settles with
a prompt pending announces once; the renderer words it "needs input" from the
host status mirror's `attention`, and answering the prompt keeps the same request
identity, so it does not announce again. The wire shape is unchanged.

* fix(native-chat): the completion says when the user is being asked

A request that settles while a prompt waits on the user was worded "needs input"
from the renderer's status-feed mirror. Remote clients receive the status and
completion streams over separate sockets, so they can arrive in either order and
the wording could be wrong both ways.

The host already knows at emit time, so the completion now carries an optional
`awaitingUser: true` in that case and omits it otherwise. The renderer words the
notification from that field alone and no longer reads the status mirror. Old
clients ignore the field and word by outcome; old hosts never send it.

* fix(worktree-status): a departed agent's failure yields to live work on the worktree card

A retained failed agent has no expiry, so ranking it with a live failure pinned the card to Failed over other panes' live work. It now ranks below working, monitoring and permission, and above every finished outcome.

* docs(agent-status): a departed agent's failure ranks below live work on the worktree card

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(cross-version): load the phone row readers without mobile's toolchain

Vite transforms a file against its nearest tsconfig, and mobile/tsconfig.json
extends expo/tsconfig.base.json, which the root-only cross-version lane never
installs. The worktree ps verdict suite imported the current phone row reader
from mobile/ directly, so CI failed with TSConfckParseError before any test ran.

The harness now imports a copy of the working-tree reader placed under the
checkout cache, where the root tsconfig applies, as it already does for the
release checkout's copy. Both readers are still the real files.

* test(cross-version): keep the checkout path-guard message and justify the copy import's cast

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* fix(agent-status): a turn a crash cut off reads Interrupted, an unproven end Couldn't confirm

When the provider gave no verdict, the structured status projection now derives
one from the newest turn's lifecycle: interrupted -> interruption, unverifiable ->
unconfirmed. Nothing new is journaled, the completion feed stays provider-only, and
the legacy interrupted flag stays a user stop only. Every verdict reader handles
both arms explicitly.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* fix(native-chat): a folded turn a crash cut off reads Interrupted after N

The settled-turn timing now carries the turn's verdict, derived by the same
agentTurnVerdict the status row uses. A turn that ended interrupted with no
provider verdict heads its fold 'Interrupted after N'; a user's stop keeps
'Worked for N'.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* fix(native-chat): the user's close of a chat records the turn it cuts short as their cancellation

The expected-close settle writes outcome cancellation when the user aimed the
stop at this chat: a Stop while the agent starts, the chat's tab closed (the
agentSession.close RPC, or session.tabs.close with a user reason), or /clear.
A quit, an idle eviction, a worktree teardown or an orchestration stop leaves the
turn with no verdict, so it still reads Interrupted.

* test(native-chat): a Claude turn a newer send superseded reads Interrupted

The supersede fires for any send Orca dispatched, the user's or another agent's,
and nothing at that site records the sender, so the turn keeps no verdict and
folds as Interrupted after N.

* fix(native-chat): the user's close records cancellation on the turn the provider settled on its way out

The Codex and Claude adapters settle their open turn as interrupted, with no
verdict, while the host stops them. The expected-close settle then found no
running turn, so a user's close of a mid-turn chat read Interrupted. The stop
now reads the running turns before it reaches the provider and records the
user's cancellation on each one it cut short, unless the provider gave a
verdict of its own. The close-verdict test's adapter now settles its turn on
close the way the real adapters do.

* test(native-chat): update the close and settled-turn expectations for the host-observed verdict

agentSession.close now passes the user's word to the host, and a settled
interrupted turn with no provider verdict carries `interruption`. Also merge a
duplicate import the code-quality gate rejects.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* fix(native-chat): the user's close cancels a turn whose start landed as the provider stopped

The close read which turns were running before the stop. A turn whose start was
still in flight (a send echo not yet journaled) was absent from that read, so the
provider's verdict-less settle on the way out left it Interrupted. The close now
reads which turns were already over instead, and records the user's cancellation
on every other turn the stop left running or interrupted with no verdict. A turn
cut off earlier, or finished during the stop, keeps its end.

* fix(native-chat): a send the provider never received after a restart has no verdict

Restart reconciliation rejects a crash-stranded send that is absent from a
trustworthy provider history with reason 'not_delivered'. Nobody failed that
send, but the verdict allowlist did not name it, so after a crash the chat
read Failed, was listed, and could notify "failed". Give the reason a shared
constant (persisted value unchanged), add it to the no-verdict set, and treat
it as an internal marker so the Retry row no longer shows the raw string.

* refactor(native-chat): the adapter settles the turn a stop cuts with the stop's typed cause

The host hands its stop's cause to the adapter's close. Each adapter settles its own
open turn on 'ended' through one mapping, turnVerdictForChildEnd, and the host's
dead-generation fallback uses the same mapping for any turn no adapter settled. A
user's close or stop of this chat is their cancellation; a quit, eviction, teardown
or an exit the adapter saw first is news.

Deletes the snapshot-and-diff reconstruction (endedTurnItemIds,
userStoppedTurnRevisions, settleUserStoppedTurns) and the requestedByUser flag.
host.close now takes a required cause.

* test(native-chat): a user's close drops the chat's status row like an eviction

* test(native-chat): expect the eviction cause on the host closes of idle release, worker stop and worker discard

The stop's typed cause now travels into host.close and the adapter's close, so these
three non-user closes assert the 'evict' they pass.

* refactor(native-chat): every stop names its cause, so none defaults to the user's cancellation

stopStructuredAgentSessionAgentUnderSerialize defaulted its ending to 'user-stop', which now
settles the cut turn as the user's cancellation. Every caller already passes a cause; the
parameter is now required, and a type-level test fails to compile if the default returns.

* test(native-chat): pin who a chat's session.tabs.close speaks for, older clients' reasonless close included

The mapping lived inline in a type-unchecked file, and only the explicit user reason had a test: an older client's reasonless close, or a lifecycle echo read as the user's, stayed green. It is now one exhaustive, type-checked function with a case per reason.

* style(mobile): draw the unconfirmed dot in the theme's status amber, not an inline hex

* docs(agent-status): the main agent's outcome also carries the host-observed end, interruption or unconfirmed

* fix(native-chat): a chat the user closed while its agent started is not a failed start

A still-starting child the user's close cut counted as a failed start, since only 'user-stop' was excluded: a start-failure row, and queued messages rejected as a provider failure. Whether an ending fails its start is now one exhaustive switch, shared by the failed-start read and the delivery loop's handover: a user's stop or close never does; an exit, a failed attach and the host's own stops still do.

* fix(native-chat): a chat the user closed closes its queued messages, and starts no agent for them

After 876b6989f1 a user's close of a still-starting chat went on like a Stop, so when the close did not complete the delivery loop started a new agent for the message queued behind it. A child's end now has three dispositions, not a failed-start boolean: a user's Stop lets the queue go on, the user's close closes what was queued before it, and any other end fails it. The close is the one a completed close does (the provider-closed rejection, no verdict), applied at the top of each delivery step and ordered against the close so a later send still goes on.

* fix(activity): a crash-cut turn draws the interrupted glyph; only a user's Stop keeps the done check

The Activity page drew every Interrupted row with the done check, which #2569 chose for a user's Stop. With a crash now reading Interrupted, that put a green check on a turn nobody asked to stop. The row's glyph is now an exhaustive switch over the verdict: a cancellation keeps the done check, and an interruption draws the existing interrupted dot. An unconfirmed end already drew its own glyph.

* fix(activity): the Interrupted group header draws the done check only when every row is a user's Stop

A user's Stop and a crash share the Interrupted group, and its header took its newest row's glyph, so a Stop newer than a crash put a green check over the crash. The header is now folded over the group's rows: the done check only when every row draws it, the interrupted dot otherwise.

* fix(native-chat): a failed close of what the user closed starts no agent for it

Rejecting the messages a user's close left queued swallowed a journal write failure, so the delivery step went on to start an agent for a message in a chat the user closed. The rejection now reports whether it landed, and a step whose rejection failed stops instead; the next wake re-derives and retries it. Also pins that the ordering against the close holds only within its epoch, since a later epoch's sequences restart.

* test(native-chat): the idle sweep's stop is an eviction, so its close carries that cause

Main's idle sweep now stops an idle agent through the conversation lifetime, which this branch gives the 'evict' cause; its expectations name it.

* fix(native-chat): a retried stop keeps the cause of the stop it finishes

A user's Stop or close whose wind-down failed after the child was proven gone was finished by the idle sweep as an eviction, so the turn it cut read Interrupted. The owed wind-down now carries its stop's cause, and a retry with no child settles with it.

* test(native-chat): the idle sweep's close of a retrying Claude chat carries the eviction cause

Main's new test expected the adapter close with the session id alone; every stop now names its cause, and the idle sweep's is 'evict'.

* fix(status): a user's Stop marks done on the tab and sidebar; red Interrupted is only a turn cut short by something else

The tab, the worktree card and the sidebar rows drew a Stop with the same red dot as a crash. The
verdict mark now maps a cancellation to done, still saying "Interrupted by user" in the row text,
and the mobile mirror follows. The Activity page keeps grouping a Stop under Interrupted with the
done check, as before.

* test(cross-version): a new phone reads a user's Stop as done; an old phone still draws it interrupted

* fix(native-chat): a user's Stop inside a live Claude chat reads as their cancellation

Stopping a running Claude turn interrupts it and keeps the session, so the turn's end comes from
the CLI's result frame. Claude CLIs before 2.1.91 send that frame with no terminal_reason, and later
ones may still omit it, so the user's own Stop was recorded as a failure with an error row.

Orca now records the stop on the open turn when it sends the interrupt. An error result for that
turn reads as the user's cancellation whatever reason the CLI gives. The stop belongs to that one
turn, so it cannot reach the next, and it is withdrawn when the CLI refuses the interrupt.

* docs(agent-status): a user's stop marks done; name the tab close cause by its type

The reference still said a stop marks a row interrupted and ranks between live work and an
unconfirmed end. A cancellation now marks done, and only a turn cut short by something else ranks
as interrupted. The runtime's tab close restated the close cause's union; it now uses the type.

* test(native-chat): a proven crash reads as an interruption on the status feed and in the chat

A crash the relaunch proves now settles its turn interrupted, and the status feed works the verdict
out from that record, so the restart test expects interruption for a proven crash and unconfirmed
for one it cannot prove, never a cancellation. A chat read before the proof lands reports
unconfirmed, then interruption and a folded "Interrupted after 27s" once the proof revises it.

* fix(status): a user's Stop reads Interrupted, and a turn anything else cut short reads Failed

The verdict mark now maps a cancellation, the user's own Stop, to interrupted, and an interruption,
a turn cut short by a crash or a killed agent, to failed, the same as a failure, which outranks live
subagent work. An unconfirmed end is unchanged. This applies to every agent, in a terminal or a chat,
on the tab, the sidebar rows and worktree card, the dashboard row, Cmd+J and the phone. A Stop is
not news, so the rollups rank it below an unconfirmed end, and notifications word an interruption
"failed". Recording is unchanged.

* fix(activity): group a user's Stop under Interrupted and a crash with failures

A user's Stop draws the interrupted glyph and sits alone in Interrupted, and a turn anything else cut
short sits in Failed, titled "Agent failed". Every row in a status group now draws the group's own
glyph, so the header is the group's status and the rule that folded a Stop's done check into the
header is gone. Interrupted ranks below an unconfirmed end, as in the sidebar.

* fix(status): draw a user's Stop in the muted tone, not the fault red

The interrupted dot, which now means only a user's Stop, draws in the muted foreground token on the
agent rows, the sidebar card and the phone. Red stays for a failure or a turn cut short by anything
else, and green for a finish.

* fix(native-chat): fold a stopped turn as "Interrupted after N" and a failed or crash-cut one as "Failed after N"

The settled turn header now follows the verdict mark: a user's Stop reads "Interrupted after N", and
a failure or a turn anything else cut short reads "Failed after N", under the new key
components.native-chat.status.failedAfter in all six catalogs and the boot catalog. Desktop and
phone share the one description, so they agree.

* docs(agent-status): describe the Interrupted and Failed marks

The reference and the phone's turn bar still described a user's stop as done and a crash as
interrupted. A fault now reads failed, a user's stop reads interrupted in the muted tone, and the
rollups rank an unconfirmed end above a stop.

* test(status): a crash the relaunch recovers marks failed

The recovery test still expected a recovered interruption to mark interrupted; it now marks failed,
as a failure does. Formatting only elsewhere.

* fix(native-chat): record a turn a newer request replaced as superseded, and show it Interrupted

A Claude turn that a newer send replaced before its result arrived was recorded as interrupted with
no verdict, which reads as a turn cut short by something else, now "Failed". It is now recorded with
its own outcome, `superseded`, where the replacement is detected. That outcome names no sender, so a
dispatch from another agent is never recorded as the user's Stop, and it sets no legacy flag.

Every reader handles it in an exhaustive switch: it draws the muted Interrupted mark with the plain
text "Interrupted", folds as "Interrupted after N", and attention demotes it with a Stop, through
the renamed agentTurnEndedOnRequest. Older builds read an arm they do not know as no verdict, which
is what this turn carried before, so their rows keep reading done; the cross-version suites pin an
older desktop's journal and status readers and an older phone.

* refactor(status): name the attention predicate for a turn ended on purpose

agentTurnEndedOnRequest becomes agentTurnEndedOnPurpose: a user's Stop or a newer request's
replacement, never a fault. The Claude turn-end comment no longer says a replaced turn carries no
verdict.

* test(native-chat): a turn cut off by a restart or by quitting Orca reads Failed after N

On main a restart-cut turn shows the done tick. Pin the chat's turn bar and
the tab's mark for both cuts, through the recovery settlement and the quit's
child-end mapping, and pin the quit's turn bar through the host's own quit.

* style(native-chat): format the superseded turn-bar expectations

* fix(claude): a Stop that names no turn is the user's stop of the open turn

The chat's Stop button names no turn. Claude's conversation Stop recorded the
user's stop only for a named turn, so an older CLI's error result after that
Stop read Failed. It now records it on the open turn through the same intent,
dropped when Claude refuses the interrupt and never carried to the next turn.

* fix(native-chat): keep the attach context's publishStatus required

The lifetime context type makes publishStatus optional, so the attach context
that spreads it no longer satisfied its own type once its duplicate
publishStatus went. The host's lifetime context is now inferred, and checked
with satisfies, so the spread carries the member it always sets.

* fix(activity): rank a user's Stop below live work in the status grouping

The Activity page's status grouping put the Interrupted group (a user's Stop, or a
turn a newer request replaced) above Working and Monitoring, so a Stop still sorted
like news there while the sidebar, worktree card and Cmd+J rank it below live work.
It now follows live work and stays above Done; Failed and Couldn't confirm keep
their places above live work.

* docs(agent-status): say which turn outcomes the journal records and which are derived

The journal now records superseded as well as the provider's verdict and a stop;
interruption and unconfirmed are derived on read. The resume row no longer claims
interrupted renders red.

* test(native-chat): the idle sweep's held-send rest closes with the evict cause, like its siblings

* refactor(native-chat): remove the unused terminal handoff

No client ever called agentSession.requestHandoff or mounted the handoff
chrome. Delete the handoff coordinator, the terminal-owner runtime, the

which released desktop clients read for worktree activation, and let
records an older build left mid handoff reconcile through the ordinary
restart and recovery paths.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

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

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

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

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

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* fix(native-chat): a Stop that names no turn stops what the conversation has in flight

Between handing a message to the agent and the agent opening its turn, there is no turn id a
client could name, so a Stop in that gap was refused as "already finished" while the agent went
on to answer. A cancel's turn id is now an optional precondition instead of its target: with
none, the host withdraws what is queued and, when the journal still reads working, asks the
adapter to stop whatever the child has in flight. Claude's interrupt is session-scoped, so it
is guarded by fence and acquisition generation rather than a turn identity. Codex interrupts
the turn its latest turn/start answered with until the journal shows one.

A cancel that names its turn behaves exactly as before.

* fix(native-chat): Stop is there from the moment a message is sent

The composer showed Stop only once the agent had opened a turn, so for the second or two after a
send the chat read "thinking" with no way to stop it. Against a host that takes a Stop naming no
turn, Stop now shows whenever the chat reads working (a turn, a queued message, or a handed-over
one still unanswered) or this client still has a message on its way. Pressing it, or Escape,
first drops every outbox entry the journal does not hold yet, so nothing goes out after the
Stop, then sends the conversation-wide cancel. A send already on its way reaches the host ahead
of the cancel, which withdraws it there. Against an older host Stop still needs a running turn.

The unconfirmed-send probe moves into its own hook so the outbox hook stays in budget.

* fix(native-chat): Stop before a turn is gated on its own host capability

A host that accepts sends first (agent-session.accepted-send.v1) can still predate the cancel
that names no turn and would refuse it as invalid, since clients and hosts ship independently.
Hosts that take that cancel now advertise agent-session.conversation-stop.v1, and the renderer
shows Stop before a turn opens, and sends the no-turn cancel, only to a host advertising it.
Every other host keeps a Stop that needs, and names, a running turn.

The host capability probe the accepted-send hook used is generalized so both read one path.

* test(native-chat): a build advertises conversation stop exactly where its cancel may name no turn

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* fix(native-chat): Stop reads the one working rule every session list reads

While Claude retries a rate-limited request it never echoes the message, so no
turn opens: the sidebar read Working from the unanswered send while the composer
showed Send. The chat's working state, the host's session-list status and the
host's no-turn Stop check now call one shared rule instead of three copies.

* test(native-chat): a rate-limit retry pins only that no turn opens, not how its rows are kept

* fix(native-chat): Stop leaves a message waiting on its Retry, and does not show for one

A send that failed holds the queue until the user retries it, and one the host restarted under is
parked the same way. Stop counted both as still on their way, so it showed in an idle chat and
could never go away, and pressing it dropped the failed message along with its Retry.

* test(native-chat): the chat's Stop and a session list read the main agent alike over their own copies

The chat reduces its stream and a list reads the status feed. Driven through the real host for a
rate-limit retry with no turn, a subagent still running after the main turn, and the handed-over
child exiting.

* refactor(mobile): the chat reads the main agent's working state through the shared rule

Behaviour is unchanged: the same two terms, now from the one function the host projection and the
desktop chat read.

* fix(codex): a Stop naming no turn never interrupts an earlier turn

It fell back to the id an earlier turn/start answered with when the latest start went unanswered,
or when the journal showed a compaction Codex had not started, and reported that as stopped.

* fix(native-chat): a Stop naming no turn never says a turn had already finished

When the provider found nothing left to stop, for instance a turn that ended between the host's
check and the interrupt, the chat got "The provider had already finished this turn." for a turn
the Stop never named. It now ends quietly, as a Stop with nothing in flight does.

* fix(native-chat): one Stop the host could not settle no longer refuses every later one

A Stop naming no turn has one operation key per session. When the host could not settle one, it
answered every later Stop under the same id as unknown until the id expired. Once the host says
so, the next press is a new Stop; transport doubt still replays the same id.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* test(native-chat): read Stop operation ids without a cast

* fix(native-chat): a Stop whose answer was lost no longer swallows the next one

A Stop that names no turn has one operation key per chat. When its answer was lost in transit, the
chat kept the id, so every later Stop replayed it; the host answers a replay as already handled, so
for up to a day Stop stopped nothing. The id is now dropped once the call settles, however it
settles. A second press while the first is still on its way still shares its id.

* refactor(native-chat): a Stop naming no target keeps its operation id only for its own call

The chat kept each write's operation id per payload across calls, and dropped it only on some
settle paths. That is right for a write naming what it acts on, but a Stop naming no turn, and a
stop of every background task, share one payload with every later one, so any path that kept the id
made the next Stop replay as already handled and stop nothing. One path was still open: an answer
that arrived after the chat moved to a new fence.

Whether a write names its target is now decided once, before its id is picked. One that names none
keeps its id only while its call is in flight, so a press made meanwhile joins it, and releases it
when the call settles, however it settles. The release runs only while the key still holds that
call's id, so a joined call settling late cannot drop a newer one's. This replaces the per-path
exceptions for a thrown call.

* test(native-chat): read the Stop fences without a cast

* test(native-chat): pin the new id for a named cancel the host could not settle

After the Stop naming no turn moved to a per-call id, the only test of the unknown-refusal release
was gone, and the half that stays, for a cancel naming its turn, could be removed with every test
green.

* fix(native-chat): a Stop pressed after a new message stops it, even while the last Stop is unanswered

A Stop naming no turn shared its operation id with any press made while it was still in flight. The
host runs a chat's writes in order, so a message sent between two presses was accepted after the
first Stop ran, and the second press replayed that Stop as already handled and left the message
running, although the chat had already withdrawn it from the outbox.

A write naming no target now gets a new id on every press and is never kept, so each Stop acts on
whatever is running when the host reaches it. A write naming its target keeps its id exactly as
before. A double press can ask the provider to stop the same turn twice, which it tolerates.

* fix(native-chat): Stop no longer blinks off as Claude opens the turn for a message

Claude's echo of a sent message both answers the send and opens its turn. The echo settled the send
first, so the host published the message as answered one frame before the turn it opened, and for
that frame the chat read nothing running: Stop turned back into Send, and Working blinked off in
every session list, for tens of milliseconds on each turn.

The echo now settles the send after the turn it opens has been emitted, so the running turn is
published first.

* fix(native-chat): a message a Stop withdrew comes back to its sender's composer

A Stop withdraws every message the host holds but has not run, and S also
drops the ones this client had not handed over yet. Either way the message
left the chat and its text survived only in a hidden journal row and the
in-memory ArrowUp history.

The sending client now puts the withdrawn text and images back in that
pane's composer, after whatever is typed there. Withdrawn is read from the
rejection reason through one shared check, which the outbox reconcile now
uses too. The composer is written before the entry leaves storage, so a
failure between the two repeats the text instead of losing it, and an entry
storage no longer holds is never given back again, so a replay, a second
view or a remount restores it once. Only this client's outbox holds the
entry, so other viewers still see the message disappear. A failed Stop
withdraws nothing on the host and gives nothing back.

* fix(native-chat): withdrawn text put back during an IME composition is not lost

While the IME owns the field, the composer ignores a programmatic draft, and
the next composed keystroke wrote the draft without the restored text, after
its outbox entry had already been dropped. The composer now holds text
appended mid-composition, keeps it in the cache after each composed write,
and shows it once the composition settles, the way attachments that land
mid-composition already wait for it.

* test(native-chat): pin that only a withdrawn message comes back to the composer

* test(native-chat): set up the composer's window API for every describe in the composition-race file

* docs(native-chat): note that the withdrawn check reads the legacy reason until a typed category lands

* test(native-chat): pin that text put back mid-composition shows once, even beside a mid-composition clear

* fix(native-chat): land a late settlement from a streamed turn's end after that turn's rows

A settlement that says a streamed turn ended waits for the session's event
sink to drain before writing its dispatch row. The journal reducer still
refuses to overwrite an accepted or rejected send.

* fix(codex): settle a send from the end of the turn Codex answered it into

The turn/start answer names the turn that holds a send. The send's echo
entry now keeps that binding, in memory only. If the bound turn is
interrupted without echoing the send, the send is withdrawn: Codex clears a
turn's pending input on interrupt, so the model never saw it. If the turn
fails first, the send is rejected in Codex's words. A completed turn settles
nothing, since Codex records pending input when it finishes and the echo is
still due. An answer read after its turn already ended is settled by that
end. The echo is still the acceptance and carries the item key.

* test(codex): a send settles from the end of the turn Codex answered it into

The fake Codex keeps 0.157's turn bookkeeping, and can deliver the turn/start
answer after turn/started or after turn/completed. The tests cover:
- a Stop before any echo withdraws the send, and the working rule reads idle;
- a steered follow-up is withdrawn when the turn is interrupted;
- a failed turn rejects the send in Codex's words;
- a completed turn leaves the send to its echo;
- a normal echo and a late echo;
- two steered sends in one turn;
- an answer read after the turn ended;
- a timed-out answer;
- child-thread turns;
- how a binding dies.

* refactor(native-chat): drop the stream flush before a late turn-end settlement

Nothing reads the order of a dispatch row against the turn's terminal row:
the reducer keeps a settled send terminal and the working state is derived
from both. The echo acceptance on the same path never waited either, and the
wait could drop the settlement on a failed sink barrier.

* fix(codex): settle a failed turn's sends at its end, not at its error

Codex keeps a failed turn's pending input and records it after the error
frame, before turn/completed. Settling at the error rejected a steered
follow-up the model had in fact received, so a Retry would send it twice.

* docs(codex): say a completed turn echoes what it took before it ends

Codex records a completed turn's pending input before `turn/completed`, so
a bound send that turn never echoed is left for recovery, not awaiting an
echo. The comments and one test title said the echo was still due.

* test(codex): settle a send whose answer is read after its turn failed or completed

A failed turn that ended before the answer rejects the send in Codex's words,
once; a completed one leaves it admitted and still armed for its echo.

* refactor(codex): read a failed turn's reason with the typed thread-fact reader

* fix(native-chat): a Stop that names no turn and ends nothing says why

The host sends a Stop naming no turn to the agent only while the chat reads
working. When the agent ended nothing, the Stop wrote no row, so it looked
ignored. It now writes one: Stop could not reach the agent, in the agent's
own words when it refused the interrupt.

* fix(codex): hold a cold send until Codex opens its turn, and stop the turn it opened

Codex answers turn/start before it opens the turn, and refuses an interrupt
until then. A Stop queued behind a cold send ran in that gap, named the
answered turn, and was refused. The send's handover now lasts until Codex
opens that turn, or provably will not: the turn ended, the primary thread
stopped running, or the child ended, bounded by the turn/start deadline.
A steered send, whose turn is already open, does not wait.

A Stop naming no turn now interrupts the turn the journal shows, else the
primary-thread turn Codex reported started and not yet ended. The per-start
answered id is gone: it was never cleared at a turn's end.

* fix(native-chat): give back a send already on its way only when the host withdraws it

Stop took the in-flight send out of the outbox and put its text back in the
composer at once. The send still landed ahead of the Stop, so the chat read
working for a moment before the host withdrew it, and a send the agent had
already taken came back as well. The in-flight send now stays until the host
answers it, and the withdrawn-message restore gives it back from that answer.

* refactor(native-chat): read a Stop's withdrawal through the rejection classifier

dispatchWasWithdrawn matched the legacy reason string. It now asks the
classifier, which reads the typed fact first and keeps that string only as its
own fallback, so a withdrawal written as a fact with a sentence is still given
back to the composer.

* fix(native-chat): a Stop Codex took but Orca could not confirm is not reported as reaching nothing

When Codex acknowledged the interrupt but Orca could not verify the turn's
processes ended, a Stop naming no turn wrote "it had no turn running to stop",
though the turn then ended as interrupted. The adapter now says the Stop was
taken but unconfirmed, and the row says Cancellation was not confirmed.

* fix(codex): a held cold send never delays closing the chat or quitting

A cold send's handover waits for Codex to open its turn, and that wait sat
in the session queue ahead of the close and quit eviction, so either could
wait out the 30 s request deadline. The host now releases those waits before
it queues a close or starts quit teardown, and the adapter releases them when
it is asked to close the child and on every exit, including one whose end
publication is backpressured.

* fix(native-chat): a refused Stop says the agent declined, and names it

"Stop could not reach the agent" was wrong: the agent was reached and
declined. The row now reads "Codex had no turn running to stop." or
"Codex didn't stop: <Codex's words>.", naming the chat's agent.

* fix(codex): a Stop waits for the turn Codex answered to open; the send no longer does

Codex answers turn/start before it opens the turn and refuses turn/interrupt
until then, so a Stop naming no turn in that window was lost. The send's
handover used to wait for the turn to open, and a close or quit needed its own
release to get past that wait.

Now only the Stop waits. A Stop naming no turn, finding no journal turn and no
open one, reads the turn Codex answered the latest pending send into and has
neither opened nor ended, and waits for it: bounded at 5 s, under the quit
eviction budget, and ended by that turn opening or ending, the thread going
idle or failing, or the child exiting. If the turn opened it is stopped;
otherwise the Stop reports that Codex had no turn running. The send returns at
Codex's answer, so a close or quit with no Stop pending is never delayed, and
the release plumbing through the adapter, router, close and quit is gone.

* fix(codex): the Stop's wait reads a stopped thread from the thread-facts reader main kept

Brennan Benson 153d3fd3fa feat(native-chat): Codex sessions write their subagents into the host status store (#22553)
* refactor(native-chat): the Codex acquire names its turn-boundary methods as a set

Behavior-neutral: the same two methods stamp receipt time. Keeps the file
under the size limit once the child-work sink lands.

* feat(native-chat): Codex sessions write their subagents into the host status store

A Codex child thread and each persistent command become host child records,
fed through the same delivery, ingest and reducer the Claude lane uses. The
child's own turn decides it: turn start is live, turn completion settles it
with the outcome Codex reports, and a follow-up turn reopens the same record
as a new run. Its open tool call, last message, usage and waiting-on-user flag
come from its own thread's frames. A parent turn ending settles nothing.

* fix(native-chat): close a Codex child's tool call by its item id alone

A completion frame need not restate the tool it ran, so reading the tool name
before closing left the call open and the record naming a finished tool.

* test(native-chat): pin the Codex child-work evidence and every hop to the host's records

Child turn start/end/follow-up, open tool call, last message, usage, waiting,
the persistent command a child owns and its monitoring display, a primary
turn end settling nothing, and session end. End to end through the real
adapter: evidence after the journal and the legacy republish, and the parent
state the records imply equals today's at every frame of a scripted session.
Through the production runtime: a Codex session's child work reaches the
status sink under its own address, and a provider exit ends it there.

* test(native-chat): a Codex child's new run never inherits the last run's open call

* test(native-chat): a Codex session with no child-work sink holds no evidence

* test(native-chat): deliver a Codex child's announcement twice, as Codex does, before counting edges

* refactor(native-chat): hand the Codex producer's pending edge over directly

* fix(native-chat): name every Codex turn state in the outcome map; type the runtime test's fake opener

* fix(native-chat): a Codex child's turn ends on the error that ends it, or on its thread closing

Codex can end a child's turn with no turn/completed: an error it will not
retry is that turn's own end (the verdict the transcript already settles the
same turn on), and a closed thread ran its last turn. The executions, the one
owner of child turn state, now end the turn on both, so the strip drops the
child and its record settles (failed, or unknown for a close) together,
instead of reading working for the life of the session. A systemError status
is not an ending: Codex raises it for errors that leave the turn running.

A child fact whose frame names no turn now belongs to the turn the child is
running, instead of counting for every run.

* test(native-chat): a Codex child's turn ending by fatal error or thread close settles strip and record together

* test(native-chat): the Codex parity script reads a waiting child through the shared fold's waiting arm

* test(native-chat): a Codex child row's journal attempt is its record's generation

The journal numbers a Codex child's runs by the turns it observed on the
child's thread; the host record numbers them by the runs its evidence
opened. Both are keyed by the child's own turn id, so they must agree run for
run, including when Codex reports the child's first turn before the spawn
that announces it.

* test(native-chat): a Codex session's end settles its live children and keeps the ended ones

The host no longer erases a session's children when its provider goes away: a
child still running settles with an outcome nobody reported, and a child that
had already ended keeps what it said. The producer tests now expect exactly
that, from the close path and from an unexpected exit.

* fix(native-chat): a Codex subagent's shell is its open tool until the process exits

Codex runs every agent shell through unified exec, so every subagent shell
arrives with the source the persistent-command tracker keys on. The producer
skipped those items, so a working subagent never named its shell, and an
approved command (started on the approval path, completed from unified exec)
stayed its open tool until the turn ended. The tracker still records the
process separately, so a command that outlives the turn reads as monitoring.

* fix(native-chat): a Codex shell becomes a subagent's own work only once it outlives its turn

Codex runs every agent shell through unified exec and never says when one is
left running, so the producer turned every shell, even a millisecond `rg`, into
a command record the moment it started. Each settled into the session's pool
of 32 settled records, so a busy turn evicted a finished subagent's record
(its outcome row would vanish) and listed dozens of finished shells beside it.

A command now becomes a record at the first turn boundary of the thread that
launched it while its process still runs: until then it is the agent's open
call. A shell that exits within its turn never becomes a record.

* refactor(native-chat): child records keep every settled child and can be removed outright

Settled child records now stay until the host drops the session's row; the
32-record trim is gone. A producer can say work stopped with nothing to
report, and its record (and the handles it answered to) goes instead of
settling. Evidence stays host-internal: the producer and the store share
one process.

* fix(native-chat): a Codex command is live work from its start until its process stops

The command tracker is now the one owner of a Codex command's lifetime. It
admits every command whatever `source` Codex tags it with (the approval
path starts one as `agent`), and ends it when its process exits, when its
thread closes (Codex stops the processes first, so no exit ever arrives),
or when the session ends. The producer mirrors that one-to-one: a live
record from the start, removed when the command stops, never settled.

This removes the turn-boundary rule: a command that was only recorded at
its turn's end left the parent reading done for one publish when the main
agent's turn ended with a shell still running. The parity script now
checks the parent at every journal write, not only at frame end.

* fix(native-chat): a Codex command whose approval its turn abandoned never ran

Codex starts an approval's command item before it asks, and when the turn
ends with the question unanswered (the user stops at the approval), it drops
the question and never completes the item. The command tracker admitted that
start as a running process, so the strip kept a phantom command row and the
session row read working until the session ended.

The prompt registry, which owns which approvals are still unanswered, reports
the command approvals a turn ended without; the tracker ends those commands
with the frame that ended the turn. An answered approval keeps its command.

* test(native-chat): start the Codex child-work runtime test without the removed hold

Main no longer has host.hold: creating the session starts its child, and
nothing a viewer does keeps it running. The test attaches and asserts the
one child that attach started, then drives it as before.

Brennan BensonandClaude a68d62911e fix(native-chat): the host writes chat failures for a person, with a typed fact beside them (#23116)
* refactor(native-chat): remove the unused terminal handoff

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(native-chat): name a chat write by its target, not the owner generation

A write carried the fence of the last frame the pane read, and the host refused it
unless that fence was still current. An idle release and the restart after it each
move the fence, and the release publishes nothing, so a send after a release was
refused "Expected runtime fence 1; the session is at 3", and a Stop queued behind a
cold start was refused as stale.

Every write already names what it acts on: a send its conversation, a cancel its
turn, a prompt answer its item revision, a rewind its epoch; an option is
last-writer-wins. So admission stops comparing the client's fence, and the rebase
that papered over one restart (admitAtResumedFence, resumedFromFence) goes with it.
The writer-lease check stays, and so does the attach's compare-and-swap.

Frames now stamp the fence read when each frame is sent instead of a copy each
subscriber kept, which went stale on the same release.

* fix(native-chat): every journal append reaches the chats that are open

A journal write and its delivery to open readers were two calls, and some
writers made only the first. A failed start whose lease could not be handed
back, a provider revision with no frame behind it, and eviction's settlement
were all journaled without reaching an open chat.

A journal handle now reports every durable change, and the host's session map
binds that report to the session's readers when the handle is set. Writers no
longer publish what they append; the per-writer publish calls are deleted.

* test(native-chat): an epoch replacement reaches the open chat

* test(native-chat): each row reaches an open chat once, and a live handle enters only through the map

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

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

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

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

* perf(native-chat): a publish behind a delivered commit reads nothing

Each commit now delivers itself, so the publish a provider frame still sends
afterwards found every reader caught up but still read rows and rebuilt the
timeline for each one. A caught-up reader now skips the read.

* test(native-chat): state why the teardown test's fake journal is safe to cast

* docs(native-chat): say mutation admission checks only the writer lease

* docs(native-chat): drop the send rebase from comments that still described it

* fix(native-chat): a message is accepted, then delivered

A send to a chat with no running agent restarted the agent inside the send
call, before the message was recorded, so the client waited for the whole
start and a failed restart refused the message. Claude held prompts sent
during startup, and those could settle as "unconfirmed".

A send is now accepted inside the session's serialized queue: one ledger row
and one submission row marked handoverRecorded, published, answered pending.
A per-session delivery loop exists while a message is queued. It starts the
agent through the same serialized attach a hold uses, waits outside the queue
for a Claude child to prove its start, and hands the oldest queued message
over as its own serialized step, writing dispatch{pending} before the adapter
call. A start it needed and did not get writes one error-tone row and rejects
every queued message with the same words; a start Stop cancelled writes none.

Settlement follows from the rows. A queued message is provably unwritten, so a
close, an eviction or an exit rejects it. A handed-over message stays in doubt.
A queued row at or below the sequence a handle found when it opened was left
by an earlier process and is rejected at open, with no latch. Stop withdraws
queued messages with no writer lease and no fence. An attach failure keeps the
conversation open, and the attach adopts its journal. Owed work counts the
loop and queued rows.

A compaction or rewind found prepared when a conversation opens was started
under a child this process no longer has, so the open settles it rather than
leaving it to refuse every send until a view attaches. The open cursor is
scoped to its epoch, because sequences restart when an epoch is replaced.

Deleted: restart-before-admission, recordFailedRestart, the fence rebase,
Claude's startup gate, the attach's forget on failure and its own crash
boundary. Clients without agent-session.accepted-send.v1 get their reply held
until the handover; the desktop and paired desktop lists advertise it.

* fix(native-chat): settle queued messages only for the child that ended

A child that proved its start and then exited before its message was handed
over left the message queued: the exit settlement returned early when nothing
else was in flight. Delivery then started another child for it, and a child
that died the same way started another, without end and without a row.

A retried settlement for an earlier generation, run by the attach that
delivery started, did the opposite: with that generation's turn unfinished it
rejected the message queued for the child being attached.

The settlement now takes the rejection for queued messages from its caller.
The unexpected exit and the eviction pass one, and it applies even with no
other work in flight; the retry for an earlier generation passes none.

* fix(native-chat): an adoption that fails to import keeps the conversation open

The attach now writes into the conversation's own open journal, but a failed
transcript import still closed it as if it were the attach's provisional one.
The conversation stayed indexed with a closed journal, so every later send
answered "could not be recorded" and every attach failed again until the app
restarted. The import now closes only a journal the attach opened for itself.

* perf(native-chat): the recovering open reads the journal once

Every conversation open now goes through the recovering open, including the
read restore of every chat at startup, which used to replay its journal once.
The recovering open replayed it twice: once to probe it and again inside the
open. The probe is now handed to the open as its load.

* fix(native-chat): an attach that fails after indexing its child leaves no child behind

A failed attach now keeps the conversation open, but a failure after
`onAttached` indexed the child (the rewind or compaction recovery, or the
attach's own success record) left that entry claiming a child the failure
path had already released. The next send found the phantom, skipped the start,
and wrote at a fence the journal had moved past, so the message stayed queued
for good. The entry now drops the released child and its event sink, and
follows the record's fence, as a failure before indexing already did.

* fix(native-chat): a withdrawn message shows no error, and a rejection outlasts the send's answer

The error strip for a message the host accepted and then did not deliver matched the entry before
the outbox reconciled, so a Stop's withdrawal, which the reconcile drops, showed "Orca could not
send your message" with nothing to retry. It now reads the reconciled entry.

A rejection the journal records before the send's own pending answer lands is final as well:
that answer no longer puts the entry back to dispatching with no Retry.

* fix(orchestration): a structured worker whose agent outlasts the preamble wait is left unknown, not torn down

The preamble waits for its submission to be delivered while the worker's agent starts. When that
wait ran out it threw operation_unknown, and the failed-start teardown then closed the session,
which rejected the very preamble the host was about to deliver. It now reports a turn start
nobody observed yet: the worker is start-unknown with its session kept, the host delivers the
preamble when the agent starts, and the worker's report settles the dispatch as for any
unobserved start. The receipt no longer suggests reading a screen a structured worker lacks.

* fix(native-chat): a message rejected while its chat was closed reads as not sent

A remount reads an entry it left dispatching as unconfirmed. When the journal had rejected it
meanwhile, as a failed start or a quit now does, the reconcile left it unconfirmed: it blocked
every later message behind a Retry and no reason, and the delivery probe, seeing the journal
already answered, never ran. The reconcile now settles it as rejected like a dispatching one.

* test(orchestration): name why the readiness settlement fakes are cast

* fix(native-chat): keep each pane's own fence on frames so a failed restart is not resent

* docs(native-chat): drop the fence from the admission the send effects run behind

* docs(native-chat): give the fence move on release the reason that still holds

* docs(native-chat): stop citing a write fence check in launch and mailbox comments

Three places still gave the removed fence check as a reason: the launch replay said admission puts the ledger ahead of the fence, the launch surface said a send must name the lease it was admitted against, and the direct-mailbox path said the lease fence decides whether delivery is safe. Admission now checks only the writer lease.

* refactor(native-chat): the provider child is its own record

A conversation now outlives any number of provider children, so the child is one record on the
conversation's entry instead of five loose fields beside its journal. It is written in one place:
indexed only once an attach has fully succeeded, and ended through one function that an exit, a
failed re-attach, a Stop and an eviction all share, matched on the child's generation and fence.

- A failed attach writes no child, so there is nothing to unwind: the field unwind and the fence
  patch after it are gone.
- Conversation writes read the record's fence, the way mutation admission already does; a child's
  own writes use its fence. The four stored-fence patches, and the settlement retry's overwrite of
  the conversation's fence, are gone.
- The owed wind-down is its own tombstone, carrying the child it is owed for, and is no longer
  dropped when an attach replaced the whole entry.
- Stop on a child still proving its start stops only the child: its lease goes back and the chat
  is told it is idle, but the journal, the holders and the readers stay. Close is that stop plus
  the conversation's close.
- The settlement retry uses the conversation's own journal, opened through the host's one open.

* fix(native-chat): the delivery loop alone settles a message its start or child failed

A queued message was settled by whichever path happened to end the child first: the loop, the
unexpected exit, eviction's work settlement, the open's leftover rule, and the startup branch that
rejected every pending row. That gave two failure rows with different tones for one start, a loop
that could hand over to a different child than the one it waited on, and a Claude start that died
while starting reading unlike every other failed start.

- The loop remembers the child it waited on. At handover, if that child is gone or replaced, it
  reads how it ended: a Stop continues; anything else writes one failure row and rejects every
  queued message with the same words, then stops. A child still starting whose start the adapter
  says did not land fails the same way. The exit, eviction and the settlement retry only settle
  the handed-over and legacy rows of the child that ended.
- One failure row, always an error, keyed by the start. A start a view began that dies with
  nothing queued writes the same row through the same builder, so a second report revises it.
- The open no longer rejects leftovers; the loop's first step does, and the open wakes it.
- `awaitStarted` answers why a start did not land, so the row says it even when the loop sees the
  failure before the exit is processed.
- Quit closes every conversation the way closing a chat does: what is still queued is rejected as
  closed, with or without a child, and a start the loop already has in flight is waited for so the
  child it produces is stopped rather than left behind.

* refactor(native-chat): a stopped child ends on the one reading of its stop

The eviction step reads a stop's result through `stopAgentSessionProviderRoot` and hands that
verdict to the child's ending, so the host never forms a second view of whether the root is gone.
Every ending carries it: a stop's comes from that reading, an exit's root is gone by definition,
and a failed re-attach passes what its release saw. The end-of-child record can therefore also
carry a stop whose root was not seen to go, which nothing ends on yet.

* feat(native-chat): the host says it accepts a send before any agent has it

The host now lists agent-session.accepted-send.v1 among its own runtime capabilities, the same
string capable clients already send. A client can then tell a host that answers a send at
acceptance, and admits a Stop with no writer before a turn starts, from an older one that still
restarts the agent inside the send. Additive: an older client ignores a capability it does not
know.

* refactor(native-chat): an attach never opens a journal of its own

The attach adopts the conversation's open journal, which outlives it, so it no longer opens one
for a direct caller either. That leaves nothing for a failed adopted import to close, and the flag
that told the two cases apart is gone. Tests that attach without a host open the conversation the
way a host does.

* fix(native-chat): a moved fence resends nothing on a host that accepts first

The outbox treated any fence change as a new owner: it dropped the answer of a send in flight,
queued that send to go out again under the same id, and unblocked a refused head. On an older
host that is how a send the restart refused, unrecorded, gets another try. On a host that records
every send before it starts an agent, a fence moves because that start ran, so the same rule
resent into every failed start. With a fence stamped on every frame, that became a loop.

The outbox now reacts to a fence change only when the host has not advertised that it accepts a
send before any agent has it. On such a host, only a Retry or a new send goes out, and a failed
start reaches the client as a rejected message it keeps with its Retry. Against an older host, or
before one has answered, the outbox behaves as it did. Desktop and paired web share this hook.

* refactor(native-chat): a child's end says whether the user or the host stopped it

The end-of-child record's cause now tells a user's Stop from the host stopping the child for a
cause of its own: `user-stop` and `host-stop` replace `stop`. The delivery loop goes on after a
user's Stop, as before, and fails the start it was waiting on after a host stop, with the one
error row and every queued message rejected, in the stop's reason when it gave one. The reason
stays description only. Stop passes `user-stop`; nothing passes `host-stop` yet.

* fix(native-chat): a chat whose only work is a queued message is not offered for resume

A message accepted while the agent was starting counts as working in the chat, and quit rejects it
as never sent. The teardown snapshot read the same working rule, so a relaunch offered to resume a
chat whose agent never had the message. The snapshot now reads only what was handed over.

* test(native-chat): type the queued-message fixtures in the resume-offer tests

* fix(native-chat): a start that dies while a message waits on it is that message's failed start

Opening a chat's tab starts an agent for the view, and a send accepted meanwhile waits on it. When
that start died, its exit wrote the start's error row and left the message queued, so the delivery
loop started a second agent into the same failure and wrote a second row. A child's end now records
where the conversation's journal stood, and the loop settles a message accepted before a failed
start ended with that start: one row, under its key, and no second start. A message sent after the
failure still gets a fresh start.

* docs(native-chat): say what an attach's open conversation and unconfirmed ids are now

* test(native-chat): pin what a failed start settles, and what a resume offer names

A view's child that dies while a sent message waits settles that message only when it died starting
and no child has taken its place: a proven child's crash, or a second start since, gets the message
delivered. The resume offer names the handed-over message, never a newer one still queued.

* test(native-chat): the failed-start pins fail on what the message became, not on a timeout

* test(orchestration): the preamble's host stub is typed, not cast

The preamble send now takes only what it reads of the host, the send, the settlement wait and the
record's fence, so its test builds that host with real types instead of `as never`.

* feat(native-chat): a typed failure fact beside every failure sentence

Adds the shared vocabulary the host writes a failure with: a closed failure kind, a
provider diagnostic that says who it is for (a person, or a log), and a refusal cause
beside the refusal code. Status rows gain an optional failure fact and rejected
submissions an optional rejection fact; the dispatch row carries it, the reducer reads
it field by field, and the projection forwards it. Older rows and older readers are
untouched: every field is optional and the schemas stay open.

* fix(native-chat): durable failure rows and rejection reasons are written for a person

Every host writer that records a failure now writes a sentence for a person beside a
typed fact, instead of embedding a refusal's message, an exception or a composed exit
string. A provider's own words travel as a separate diagnostic from the places Orca
composes them - the Claude and Codex exit stderr (a log), Codex's JSON-RPC message,
Claude's compact_error and Codex's turn error (for a person) - and are never inferred
from a string afterwards. Not signed in and oversized history are typed at the
adapter that detects them.

Covers start and restart failures, the delivery loop, dispatch rejections (content,
queue-full, write failures, provider refusals), cancel and answer confirmation rows,
compaction, the rewind fallback, and not_delivered, which released clients printed
as it was. Two leaks close on the way: a settlement retry no longer writes Orca's
probe evidence into the exit row, and an attach or journal-sink failure is recorded
as Orca's fault rather than as the provider stopping. The legacy rejection markers
and the reasons on sends in doubt stay byte-identical.

* feat(native-chat): refusals name their cause, and a failed start is worded in one place

A refusal now carries an optional cause beside its code: one closed enum of the situations
a chat write can meet, set at every emitter a structured-chat write reaches. Returned
refusals build it with refuse(code, cause, message). Store and host paths that raised a
bare Error(code) now throw AgentSessionRefusalError, whose message is still the code and
which has no code property; the RPC error mapper handles it before any other passthrough,
keeps today's wire code and message byte-identical, and adds { refusal: { code, cause } }
to the error's data. The hold throws it, and restart-resume files the cause beside the
unchanged reason. The operation ledger stores the cause beside the code, so a replay names
the same situation as the first answer. The store fallback copy picks its words and cause
by situation, so a stale replay or a moved lease no longer reads as a latched owner.

Every failed start is worded by structuredAgentSessionStartFailure(cause, context), which
returns the row sentence and the typed fact together; the delivery loop, the exit
settlement and the dispatch that met a starting child all call it. Provider diagnostics
are capped at the lease record's 512 characters wherever a fact is built.

* refactor(native-chat): one reader of why a submission was rejected

classifyDispatchRejection(submission) returns { category, verdict, kind? }. It reads the
typed rejection fact when the row carries one this build can place, and the legacy
markers otherwise - all six, including not_delivered, which released clients printed as
it was. The verdict is null only for a withdrawal, a host restart and a closed chat;
write failures, a full queue and not-delivered stay failures. It replaces
dispatchRejectionReasonIsInternal and every string comparison against the markers: the
outbox reconcile, the rejection notice, and the send disposition, where a replayed
Stop-withdrawn send no longer surfaces as a failed send.

The journal reducer's echo-aliasing guard reads the narrow isWriteFailureSubmission,
which matches the typed kind or the legacy prefix in any dispatch state, so its behaviour
on legacy unknown rows is unchanged.

* test(native-chat): pin provider diagnostics where they are composed

The Claude exit status and stderr, the Codex stderr tail and Codex's JSON-RPC message are
each checked at the place Orca composes its own error around them, so the typed detail
is proven to come from the provider's value and never from Orca's wording.

* fix(native-chat): an attachment Orca refuses says which limit it broke

The content check's refusals (20 images, 5 MB per image, 20 MB in total, supported types) are
written for a person, but the rejection writer replaced them all with one generic sentence.
Each refusal now carries its own sentence, in MB rather than bytes, and the writer records it
beside kind attachmentInvalid. Only an attachment that could not be read keeps the generic
sentence.

* fix(native-chat): the chat tab table refuses with a typed cause

Showing a chat tab refused with bare Error('agent_session_conflict') and
Error('agent_session_identity_required'), the only chat-reachable refusals still thrown without a
cause (opening a chat from history can reach the second when the chat is removed mid-open). Both
now throw the typed refusal; wire code and message are unchanged.

* fix(native-chat): a compaction Codex refuses up front keeps Codex's words

When Codex refused thread/compact/start, the adapter passed on only Orca's wrapped error text and
dropped Codex's own message, so the chat's row read just "Compaction failed." The refusal now
carries Codex's message as the failure detail, as a compaction that fails later already did.

* fix(native-chat): an unreadable chat record no longer promises an update fixes it

The recordUnreadable copy said a newer Orca saved the chat, but the store marks a record
unreadable for damage and key mismatches too, where updating does nothing. The sentence now says
Orca can't read it and gives both next steps.

* fix(native-chat): a restart or a close leaves released clients a sentence, not a marker

host_restarted_before_delivery and provider_closed_before_delivery are not in the markers released
desktop and mobile builds hide, so they printed raw on every rejected message a restart or a chat
close left. Neither marker has shipped. New rows carry a sentence plus kind hostRestarted or
chatClosed, as not_delivered already did; the classifier still reads both markers, and the
verdict for both stays no-failure.

* fix(native-chat): log why an attachment could not be read

The rejected message now says only that the attachment couldn't be read, so the error that said
why (a missing file, a permission, or an unexpected throw) went nowhere. It is logged instead. The
content rejection moves beside the content check that owns its errors.

* refactor(native-chat): drop an unused thrown-refusal cause reader

It had no callers, and its comment claimed it looked through wrappers, which it did not.

* fix(native-chat): a compaction the provider never confirmed is recorded as unconfirmed, not failed

* fix(native-chat): an empty or non-user message is not recorded as a bad attachment

* fix(native-chat): an undelivered preamble's error ends in one period

* refactor(native-chat): a compaction ends as compacted, failed, or unconfirmed, never an unlabelled error

* refactor(native-chat): a failure's sentence is written only from its fact

A writer could choose its sentence and its kind separately, so five writers
put hand-written words beside a fact that said something else. One shared
constructor, agentSessionFailureWords(fact, { surface, agentName }), now
makes both, and the journal types refuse anything else: a status row, a
rejected message or a conversation command that carries a fact must carry
the sentence that constructor branded. Persisted rows keep their shape.

- The sentence table and the restart table move to src/shared, as the English
  default a client copy table can reuse.
- A rejection's legacy markers come from the same constructor. A write
  failure is now the bare `provider_write_failed` marker, which released
  clients already hide; its error goes to the log.
- An image Orca refuses carries which check it failed (and the limit) in the
  fact instead of a sentence; an empty message gets its own kind, and a
  non-user message is Orca's fault.
- The exit row, the interrupted compaction, the /clear failure and the rewind
  placeholder no longer carry their own words beside a fact: the exit row
  says what its fact says, and the placeholder carries no fact.

* fix(native-chat): a start that failed without an observed exit no longer blames the provider

Every untyped start error was recorded as "The provider stopped before it
finished starting.", so an Orca fault, a failed spawn or a close that ended
a start was blamed on the provider. Only an exit the adapter observed says
so now: the Claude adapter marks the error it saw the child exit with, and
anything else is a new `startFailed` kind, "<Agent> couldn't start.", keeping
the provider's diagnostic when the error carried one. A child gone with no
end observed, and a /clear whose new conversation was refused, read the
same way.

* fix(native-chat): a view never restarts a chat whose last start failed

A Claude chat whose CLI exits during startup left one red row per start, and
every time a view bound to it (the chat opening right after its create died,
or the user switching back to it) the hold started the CLI again, so the same
launch-failure row repeated. Only a send retries a failed start now, the same
rule provider-exit recovery already applied; the rule lives in one predicate
the hold, exit recovery and the delivery loop share.

* fix(native-chat): a chat a terminal agent still holds says to quit that agent

The merged base words a restart a terminal agent's claim refused with the
refusal's own message, which names the process. That message is Orca's text
and never reaches a durable row here, so the row read only "<Agent>
couldn't restart." and lost the one step that frees the chat. The restart
sentence now derives it from the refusal's cause: a claimConflicted refusal
adds "This chat is still open in a terminal agent. Quit that agent to
continue the chat here." The live refusal still names the process.

The restart-resume ledger test now sets up a claim the base still refuses:
a terminal owner that is proven running.

* refactor(native-chat): keep the changed files inside their lint limits

The legacy-marker lookup is a table, not a non-exhaustive switch; the
preamble tests read the error without a cast; and the Codex history refusal
goes through a named constructor so its file stays under the line limit.

* test(native-chat): start the child the loop waits on with an attach, not a second view

A view no longer starts a child whose last start failed, so the R2 case that
waits on a child started since the failure now gets that child from a client
attach, the one non-send starter left.

* fix(native-chat): settle a gone generation's turn wherever a conversation opens

A send that opens a chat this process had not read yet (after a crash, from a
phone or the CLI) went through the delivery open, which never settled what the
dead generation left running; only the read restore and a successful acquire
did. When the send's start then failed, the turn stayed running for every
reader. The settlement now runs in the one journal open, at the crash boundary,
for every opener except an acquisition, which settles from the evidence it read
before its reserve; the read restore's separate step is gone.

* test(native-chat): prove the next child's start settles the turn an earlier child left

The R1 case lost its only settlement assertion when the latch it checked was
deleted. It now seeds the running turn the earlier child left and asserts it
ends at the exit's receipt, with the exit's row, before the message is handed
to the new child.

* test(native-chat): count a failed start's rows by row, not by text

Comparing the set of texts passed when two different rows carried the same
words, which is the duplicate the test exists to catch.

* test(native-chat): give the failed-start and stale-turn waits a loaded runner's budget

* refactor(native-chat): refusals carry details keyed by their code

A refusal named its situation with one flat cause list shared by every
code, so nothing stopped a site pairing a code with a situation that code
never means, and the loose fields released clients read (fence, revision,
resolution, verdict, rewind reason) were written by hand at each emitter.

A refusal is now one variant per code with optional details: a reason that
code lists plus that code's own facts. refuse(code, details, message)
rejects a reason the code does not list at compile time, and it is the one
place the loose top-level fields are copied from details, so released
clients read exactly what they read before. A site that cannot name its
situation uses refuseUnclassified, which carries facts but no reason, the
same as an older host; there is no catch-all reason.

Thrown refusals put { refusal: { code, details } } in the RPC error's data
(wire code and message unchanged). The operation ledger, the restart-resume
record and a restart failure's embedded refusal keep details beside the
code and read them back against it; a row an unreleased build wrote with a
cause parses and reads as naming none.

* test(native-chat): pin the open's and the send's start and row counts, however the view binds

Opening a fresh chat whose starts fail makes one start and one row, with two
views bound before or after the create's child died; one send makes one more
of each.

* test(native-chat): a restart-resume failure keeps its refusal details

The recovery capsule reads a failure's details back against the refusal
code in its reason: facts the code does not list and a reason another code
owns are dropped, and a record an unreleased build wrote with a cause
still parses, naming nothing.

* test(native-chat): import the failure words once in the provider child test

The merge left two imports of the same modules.

* fix(native-chat): settle a gone generation's turn at every open but an acquisition's

The journal open skipped the settlement whenever the lease read reserved or
live, to leave an acquisition's own open to the acquisition. But a lease a
crashed process left in recovery also reads live, until the next acquire
resolves it. A send that opened such a chat, from a phone or the CLI after a
crash on a host that could not prove the old owner gone, skipped the
settlement; when its start then failed, the dead turn stayed running for every
reader. The acquisition now says it is the opener, and every other open
settles, whatever the lease still claims.

* test(native-chat): hold the create's start open until the views bind

The "view binds while the create is still starting" case gave the create a
300 ms head start and asserted the views bound before it died. On a loaded
runner the holds took longer, the create's exit landed first, and the case
failed its own precondition. The create's initialize now waits on a gate the
test releases once the views are bound.

* fix(native-chat): a start the provider refused or Orca broke no longer says the provider stopped

A failed start whose cleanup proved the child gone was typed as
`providerStartFailed` whatever failed it: Codex refusing to resume a thread,
a timeout, or Orca's own store fault. The chat then read "The provider
stopped before it finished starting.", which was untrue, and the provider's
own words were dropped. A refused restart also inferred the same from an
`exited` verdict, which only says nothing runs now.

Only an exit the adapter observed names that situation now; anything else
is refused with no reason, keeping its verdict, and the chat reads
"<Agent> couldn't restart.". The provider's words travel host-side from
where the acquisition failed into the start-failure fact's detail, never
onto the refusal, and the sentence does not quote them. What failed is
logged once where the start failed.

* fix(native-chat): a refused /clear start keeps the situation it named

The replacement start that /clear makes built its own start-failure fact,
so a refusal that named its situation, such as not being signed in or a
history too large to restore, was recorded as a bare "couldn't start". It
now takes its fact from the same start-failure function as every other
start, as a new session that failed to start.

* fix(native-chat): the journal schema and comments describe a refusal's details, not its cause

The persisted failure fact's schema still described `refusal.cause`, which
this branch replaced with `details`. It now describes `details` as an
optional open object; a row an earlier build wrote with a `cause` still
parses. A comment and three test descriptions that still named the cause
now name the details.

* fix(native-chat): a Claude child that exits while being acquired still reads as the provider stopping

Now that only an exit the adapter observed says the provider stopped, the
exit the Claude adapter saw during acquisition has to be marked where it is
seen, as the exit after acquisition already is. Without the mark, a Claude
CLI that exited at spawn read "Claude couldn't restart." instead of "The
provider stopped before it finished starting."

* fix(native-chat): word a failed chat start's refusal as its start failure

A chat whose agent failed to start answered the create with the raw error: the launch strip read "Chat could not be started. claude stream-json exited (code 1): claude: not signed in", and the ledger replayed the same text. The first answer and the replay now carry the sentence the chat's start-failure row reads as ("The provider stopped before it finished starting.", "Claude couldn't start.", the not-signed-in and history-too-large sentences), and the raw error goes to the log. A store refusal's code and the unproven-exit marker are unchanged.

* fix(native-chat): show Claude's API retries as one sentence row

While Claude retried a refused request (a 429, say), the chat gained one red row per attempt reading "rate_limit", with the raw retry frame behind Details. Each retry run now writes one warning row that later attempts revise in place: "Claude is rate-limited and retrying." for a rate limit (error `rate_limit` or status 429), and "Claude hit a temporary problem and is retrying." otherwise. The row carries a `providerRetrying` fact with the provider's error type and status, and the frame as a log detail capped at 512 characters.

* fix(native-chat): tell the user to run /clear again when its new conversation can't start

When /clear's replacement conversation failed to start, the result told the user to "send your message again", which would go into the old conversation. The failure words now take the command the start was for, so a failed /clear reads "Codex is not signed in for the selected account. Sign in, then run /clear again.", "Codex couldn't start. Run /clear again." or "The provider stopped before it finished starting. Run /clear again." A message send keeps its wording.

* test(native-chat): expect a failed Claude create to be refused in a sentence

The runtime suites asserted the CLI's stderr reached the create refusal; it now goes to the log and the refusal reads as the chat's start failure.

* fix(native-chat): name the agent that stopped starting and say how to retry a failed start

A start the provider ended now reads "Claude stopped before it finished starting." (or "The agent ..." when the chat's agent is unknown) instead of naming "the provider". A start or restart that failed with a chat left to retry now ends in "Send your message to try again.", or "Run /clear again." for /clear; released clients print only this sentence. A message rejected at dispatch because its child died while starting names the same agent as the start's row.

* refactor(native-chat): drop the composer's second error formatter

After the merge with main, every chat write in the composer path reports its
failure as a typed outcome worded by the refusal-notice table, so the send's
catch sees only a local throw. The {code, message} formatter this branch added
for it has no payload left to format, and its claim to be the one way a chat
words a failure is no longer true. The composer send is main's again.

* test(native-chat): pin the reason on a message rejected while its chat was closed

The reopen test checked only that the message reads as not sent; it now also
checks the Retry row carries the host's reason.

* fix(native-chat): answer a create refused before spawn in the words its replay reads

A create that failed before any process started threw Orca's own error text as its first answer,
while its replay from the operation ledger read the generic start sentence. The two refusals a
person can act on, a launch whose Anthropic sign-in variables override the managed Claude account
and a Claude account switch in progress, are now typed where they are thrown and worded by the
shared failure constructor, so the first answer and the replay say the same thing. Every other
pre-spawn failure reads the generic start sentence, with its own text in the log. The first answer
keeps its wire code; a message that is itself a code is unchanged.

* fix(native-chat): say how to retry after an agent stopped before it finished starting

"<Agent> stopped before it finished starting." gave no next step outside /clear, unlike every other
failed start. It now ends "Send your message to try again.", the same step a start or restart that
could not run gives; after /clear it still says "Run /clear again."

* fix(native-chat): say how to reach a Claude chat when a WSL Claude account blocks it

A Claude chat that restarts while a Claude account is added in WSL and no Windows Claude account is selected was refused before spawn with Orca's own text as its first answer, and the generic start sentence on replay. The refusal is now typed where the account gate throws, and both answers read the same sentence: choose or add a Windows Claude account in Claude Accounts settings, then send the message again. Account settings that cannot be read name no situation and keep the generic sentence.

* fix(native-chat): say the reason a host names for a refused chat write

A refused Stop, answer, setting, goal, command or queued message now reads the refusal's reason as
well as its code. A code stands for several situations, so the code alone could only say what did
not happen; with the reason, the notice says why and, where the person has a step to take, what it
is: "The agent is still responding. The command didn't run. Wait for the agent to finish
responding, or stop it." The phone uses the same words.

The notice table keys on code, then reason, then the kind of write. Every reason of every code has
an entry, so a reason the host adds does not compile until it has words; a reason whose honest
words are its code's keeps the code's row. A refusal with no reason, or one this build does not
know, reads exactly as before, which is what an older host gets. A start that failed reuses the
failure row's own sentence rather than a second one.

A queued message keeps the reason, the rewind reason and the owner's verdict with its saved
failure, and a rejected one keeps the host's typed fact without its provider detail. Nothing that
moves with the owner or comes from the provider is saved; entries saved before this load as they
were. The saved failure moves to its own module beside the words chosen from it.

* fix(native-chat): retry a refused send under a new id only once its agent is proven gone

A send refused because Orca could not tell who owns the chat keeps its operation id, since the
first attempt may still land. When the refusal also says the agent process has exited, nothing can
run that attempt, so the message moves to its Retry row under a new id instead of holding the queue.

The owner's verdict is read as a floor: a saved `exited` is final, and any other saved verdict never
changes the id on its own. Only a verdict re-derived from the current lease can raise it to
`exited`, and nothing lowers a saved `exited`. Today no host sends a verdict on a send refusal, so
nothing a person sees changes; the rule is in place for the saved verdict a reload reads back.

* fix(native-chat): say a /clear that never finished did not finish, instead of that it cleared the chat

A send into a chat whose /clear started but never committed was refused as if the conversation had been cleared: "This conversation has been cleared. Your message was not sent. Open the current conversation to continue." The clear never finished, so its new conversation may not exist and there is nothing to open. That refusal now has its own reason and reads "The last /clear didn't finish. Your message was not sent. Start a new chat to continue.", which is the only way on today. Its message for released clients says the same: "The last /clear didn't finish. Start a new chat to continue." Only a committed /clear still says the conversation was cleared.

* fix(native-chat): a send the provider never received after a restart has no verdict

Restart reconciliation rejects a crash-stranded send the provider's history
proves it never received. Nobody failed that send, but the verdict table
treated it as a failure. Each rejection kind now has its verdict in one
exhaustive table, so a new kind does not compile until its verdict is chosen;
no verdict for a withdrawal, a host restart, a chat close, or this lost send.

A rejection whose kind this build cannot place, such as one a newer host
added, now reads as undelivered with no verdict instead of falling back to the
reason beside it: all it proves is that the message did not happen. The host
keeps such a fact's kind when it reads the row back, rather than dropping it
and letting the reason decide.

Only kinds that can be why a message was not sent may reject one, by type:
compaction, cancel/answer confirmation and provider-retry kinds stay on status
rows. The one dispatch-row builder takes its input from the type that makes a
rejected row carry its fact.

* fix(native-chat): a send refused after its agent exited keeps its place in the queue

When Orca cannot tell who owns a chat but the refusal says the agent process
has exited, the next attempt may use a new id, since nothing can run the old
one. It no longer marks the message as rejected: nothing recorded it, so it
still holds the head of the queue, and later messages wait behind it instead
of being sent ahead of it.

* fix(native-chat): stop reading a provider's words from an error that contains itself

A cleanup that aggregates errors restarted the depth count for each one, so an
aggregate error that contains itself recursed until the host ran out of stack.
One depth bound now covers both the cause chain and the aggregated errors.

* fix(native-chat): say a chat whose history can't be read can't continue, and to start a new one

A read of a chat's history is refused with `agent_session_journal_unreadable` only when the chat's journal file is corrupt or not a database, which no retry can change. The notice table had no words for a read at all, so a pane had nothing to show but the raw code. Reading a chat's history is now its own request kind, `read-history`, and that refusal on it reads "This chat's history couldn't be read, so it can't continue here. Start a new chat to continue.", whether the host names the reason or raises the bare code. A write refused under the same code keeps its words, because its cause is any failed open, which can clear. Any other read refusal says only "This chat's history couldn't be loaded." `agentSessionReadHistoryRefusalParts(code, details)` gives a pane those words from a read error.

The notice sentences move to their own module so the table stays within its size limit.

* fix(native-chat): decide what every way a child ends means for queued messages in one table

What a child's end means for the messages queued behind it was an if-chain: a user's Stop was checked in one place, a host stop in another, and every other cause, including one added later, fell through to "the provider exited". It is now one table over every end cause, so a new cause does not compile until someone says whether it fails what is queued and how. A user's Stop still fails nothing, a host stop is still Orca's fault, and an exit, a failed attach or an eviction still carry the failure the end recorded. Nothing a person sees changes.

* test(native-chat): a close that stops the child and then fails rejects what is queued by how the child ended

When a chat closes, stops its agent, and then fails a later step, the chat stays open with its messages still queued. The delivery loop then rejects them by the way the child ended: an eviction during startup reads as a failed start, otherwise as the provider having stopped, and either counts as a failure. The cases are rows over the end cause, so another way a chat closes is one more row.

* test(native-chat): type the refusal a persisted-schema test admits

* fix(native-chat): say whether a chat's history is damaged or just couldn't open

A write refused because the chat's journal would not open named one reason, `journalUnreadable`, for every failed open, and a read of the history took that same reason as final. So the words depended on what was asked, not on what happened: a busy or permission-denied open could tell a person to start a new chat, and a damaged one could read as something that clears.

The host now decides at the refusal which it was. `journalCorrupt` is set only when SQLite itself reports the journal damaged or not a database (SQLITE_CORRUPT or SQLITE_NOTADB, extended codes included, read from the driver's result code and never from message text, through any `cause` chain). Every other failed open is `journalUnavailable`. A corrupt history reads "This chat's history couldn't be read, so it can't continue here. Start a new chat to continue.", with "Your message was not sent." before the step on a send. One that couldn't open reads "Orca couldn't open this chat's history right now. Try again.", likewise on a send. A host that names no reason gets "Orca couldn't read this chat's saved history.", which promises neither, because damage can't be proven from the code alone.

The refusal's message, which released clients print for a send, is now that person sentence instead of the open error's own text; the error is logged instead. `journalUnreadable` is replaced outright: no released build wrote it, and a stored one reads as a refusal with no reason.

* docs(native-chat): say why a history that couldn't open names its retry step

* fix(native-chat): a failed start's row keeps the words its rejected messages carry

When the delivery loop settles a failed start before the child's exit is published, it writes the
start's error row and rejects every queued message with the adapter's startup answer. The exit
settlement then rewrote the same row from the exit event, so the row could say one thing while the
rejected messages, which are terminal, said another. The exit now leaves a start's row it finds
already written.

* fix(native-chat): a Claude start Orca itself failed no longer says Claude stopped

Every error that ended a Claude session was marked as an exit the adapter
observed, including a start Orca failed while the CLI was still running: a
saved option whose restore lost its answer, an init frame naming another
session, or a journal write fault. Those read "Claude stopped before it
finished starting." although Claude never stopped on its own. The mark now
stays where the child's exit is seen (the connection's exit callback), so
those starts read "Claude couldn't start." with any diagnostic beside it,
and a real exit before the start lands still says Claude stopped.

* fix(native-chat): name the agent that stopped, and blame Orca for its own closes

A chat that lost its agent mid-response said "The provider stopped…", and a
started Claude session that Orca itself closed after a journal fault said the
same, as if Claude had exited on its own.

The exit row and the rejected-message reason now name the chat's agent ("Claude
stopped while this response was in progress…", "Codex stopped before this
message was sent."), or "The agent" when the name is unknown; the stale-state
settlement now passes the agent name too. After a Claude start has landed, the
ended event reports providerExited only when the child's own exit was observed;
any other close is Orca's fault and reads as one.

* test(native-chat): pin the sidebar verdict to the rejection classifier for every kind and legacy marker

* fix(native-chat): blame Orca, not Codex, when Orca closes the Codex child

A Codex chat that Orca itself closed (a journal sink that could not take a
frame, or a forced close) said "Codex stopped while this response was in
progress", as if Codex had exited on its own.

Orca's own close path now reports hostFault. providerExited is left to the
app-server connection's exit callback, which the connection withholds while Orca
is closing the child, so it only ever reports the child's own exit.

* fix(native-chat): a chat whose history is damaged reads "Unable to load this chat."

* fix(native-chat): route the conversation-outlives-agent writers through the typed refusals

Three writers that arrived with the merge wrote refusals the old way:

- An operation that starts the agent itself, such as a goal change, turned any error the start
  threw into a refusal whose message was Orca's own error text, which released clients print.
  It now logs the error and says only that the agent couldn't restart.
- An option picked while the chat is at rest, for a key the provider would not accept, is refused
  with the rejected-option reason, like the same pick on a running agent.
- A restart continuation whose agent was refused a start filed the rejected message's sentence as
  the failure's reason. It files the refusal's code with its details again, which is what the
  restart-failure guidance keys on.

* fix(native-chat): a start Orca stopped because it never finished reads as that

The idle sweep now stops an agent whose start never finished and rejects the messages waiting on
it. The chat read "Orca ran into a problem, so this didn't go through. Try again." for that,
because every host stop was worded as Orca's own fault. It now reads "Codex never finished
starting, so Orca stopped it." in the chat's row and on each rejected message, carried as its own
failure kind so newer clients can tell it apart. The message counts as failed, like any start that
did not land.

* test(native-chat): pin the merged close and host-stop rows to their typed facts

The merge left two expectations on the old words: the close tests looked for the marker a close
used to write, and the host-stop test for the host-fault sentence. A close now writes "The chat
closed before this message was sent." with its fact, and a host stop the hostStopped sentence the
constructor gives, whatever reason the stop carried. Also folds the conversation command's two
imports from send preparation into one.

* fix(native-chat): a read of a chat this host cannot open says why

Reads now reach a chat through one accessor, which refused a missing record and a provider this
host does not run as a bare code with nothing beside it. Revealing the same chat already names
those reasons, so a client could tell "this chat no longer exists" and "update Orca" apart there
but not on the history or subscribe read that follows. The accessor now throws the same typed
refusals. The wire code and message are unchanged; the reason rides only in the error's data,
which released clients ignore.

* test(native-chat): a Claude retrying past the idle window keeps its conversation open

Every api_retry frame publishes the journal, and that publish is the activity the idle sweep reads, so a retry run revised into one row still renews the clock on each attempt.

Brennan Benson 067975bfd1 fix(native-chat): every lease latch has a way to die (#22820)
* fix(native-chat): every lease latch has a way to die

A failed exit settlement no longer leaves the lease in recovery: the release
writes no stage and keeps the exit in its death evidence, and whatever the dead
generation left running is settled from that evidence at the next acquire or
read restore. The settlement retry flag, its disposition and every branch that
read it are gone. A reservation that recorded no process is released at
startup and after a failed start, the never-written conflicted status and the
processless proof are deleted, recovery resolution always concludes, and Codex
records its child's identity at spawn, before the handshake.

* test(native-chat): a re-create needs a release proven by death evidence

* test(codex): the child's pid is reported before the handshake

* test(native-chat): type the crash and exit fixtures without casts

* fix(native-chat): wait out a terminal owner an older build recorded, in recovery rather than manual recovery

* test(native-chat): a chat mid-turn at quit reopens idle, and an older build reads an unproven release

* test(native-chat): explain the baseline store cast

* fix(native-chat): a terminal owner's refusal names the process instead of recursing

Opening a chat whose terminal owner an older build recorded threw a stack
overflow instead of the refusal that names the process to quit.

* fix(native-chat): wait out a terminal owner recovery cannot verify instead of releasing it

A terminal agent an older build recorded keeps its PTY across an Orca
restart, so a probe that cannot answer (a start-time read that fails on a
loaded host) is not evidence its transport is gone. Releasing it let a
native child resume the same conversation beside the live terminal agent.
Only proof of its exit now ends the claim.

* ci(cross-version): run the unproven-release downgrade test

The sharded unit job excludes tests/e2e/cross-version-wire, and the
cross-version job runs an explicit list that did not name the new test,
so it never ran in CI. A change to the record validator now also starts
the job.

* refactor(native-chat): map the retired manual-recovery stage to recovering at decode

Nothing in this build writes manual-recovery, and restart reconciliation
already rewrites it. Mapping it where the other retired handoff stages are
mapped removes it from the in-memory lease type and deletes the branches
that could only see it: the acquisition refusal, the renewer skip, the
unproven-release stage check, and the handoff-status 'manual recovery is
required' answer. Older builds accept recovering, so a record written back
still loads after a downgrade.

* docs(native-chat): say what happens to a live child an ownerless reservation leaves

The reaper runs once at store open, while the unreconciled lease still
claims the child's token, so it does not stop that child on this launch.
The comment claimed it did.

* test(native-chat): name the each-case label for its role

* fix(native-chat): continue a create retried after recovery released its reservation

The client retries a create it never heard back from under the same operation id.
Recovery had released that create's reservation, so the retry was refused
agent_session_ownership_unknown while its row was pending, and
agent_session_operation_expired once the row aged out, and the chat never started.
A retry whose lease nothing holds now continues as a fresh reservation at the next
fence, which also stops the old reservation's spawn from committing.

* test(native-chat): name the refusal a replayed create used to get

* fix(native-chat): one quit-the-terminal-agent message for a chat a terminal agent holds

A chat held by a terminal agent an older build recorded frees only when that agent
exits. Sending said to reopen the chat and opening it said two runtimes claimed
it; both now say the chat is open in a terminal agent, name its process, and say
to quit it. Error codes are unchanged.

* ci: run PR checks on the rebased head

* fix(native-chat): name a terminal owner's process only when its start time can tell it from a reused pid

* test(native-chat): relaunch from the dying host's durable state, so its still-pending attach cannot race the new host

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

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

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

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

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

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

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

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

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

* test: read the sent operation id without a cast

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

This reverts commit e52c4a6f08.

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

This reverts commit 136a39deb0.

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

This reverts commit 39234e44bf.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Brennan BensonandMerge Sim 955051ded0 fix(codex): settle a structured send on admission, and stop minting a colliding identity (#20138)
* fix(codex): settle a structured send on admission, and stop minting a colliding identity

Two sends could be written into the journal under one durable identity.

Codex coalesces a mid-turn `turn/start` into the running turn rather than
refusing it -- measured against real `codex app-server` builds 0.147.0,
0.150.1 and 0.153.4, none of which refuse and none of which fire a second
`turn/started`. The dispatch path read the turn id from the turn/start
response and stamped every accepted send `ordinal: 0`. Since a coalesced
send gets the running turn's id back, two submissions persisted the same
`providerItemId`. That string is durable, and it is the key a restore uses
to match a submission against provider history, so the second message's real
history row matched nothing and rendered as an extra bubble on replay.

On 0.147.0 it is worse than a collision: the coalesced response returns a
turn id that never starts and never completes, so the persisted key named a
turn absent from history and NEITHER message could match.

Identity is now minted from the echoed user message at `identityFor` -- the
single point that mints the journal row's own identity -- so the settled key
is by construction the one replay computes, rather than a parallel
calculation that can drift.

Dispatch returns `admitted` when the transport write completes; identity
settles on the echo through a channel that did not previously exist for
Codex. Waiters are keyed by client message id instead of being shifted off
the front of an array by arrival order, and they are cleared on session
close and child exit -- previously a timeout was the only thing that ever
ended one.

`TURN_ID_WAIT_MS` is deleted. It was never reachable on any build measured:
`readCodexTurnId` returns non-null on all three, so the 10s wait never
fired. The comment justifying it claimed older builds acknowledge before the
id exists, which no tested build does.

Three comments asserting Codex answers a mid-turn send with `turn already
running` are corrected. Their only backing was a test fixture inventing that
error string. The correction is factual only -- every changed line in
`src/main/runtime/orchestration/` is a comment, and mid-turn delivery is
still refused for both providers. Whether that policy is right is a separate
question; it was resting on a false premise.

Known gap, stated rather than implied: this prevents new collisions and does
not repair journals already written with a colliding or phantom key. Those
conversations keep duplicating on restore. Repairing them means re-matching
persisted submissions against provider history and rewriting
`providerItemId` -- which is what `journal-submission-reconciler.ts` is
written for, and it still has no production caller.

* test(codex): drop the synchronous-accept contract and the colliding `:0` from the integration fakes

Three tests in the structured-session integration suites encoded the dispatch
contract this branch replaces, and two of them pinned the defect it fixes.

They asserted `agentSession.send` answers `dispatchState: 'accepted'` carrying
`providerItemId: codex:<thread>:<turn>:0` at send time. That ordinal was never
observed; it was stamped on every accepted send, which is exactly the collision
this branch removes -- a send coalesced into a running turn is answered with the
running turn's id, so two submissions persisted one durable key.

The visible failure was a 30s timeout rather than a failed assertion. The fake
client advertised no `agent-session.pending-send-result.v1`, and without it the
host holds the reply until the send settles: a shim for clients too old to
render a pending bubble. The fake provider then echoed the user message with no
`clientId`, so nothing could correlate that echo back to the submission, and the
wait ran to its own 30s ceiling. Real Codex sends `clientId` on that echo, and
the fake now does too, which is what makes it a model of the provider rather
than a sketch of one.

The identity assertion is kept rather than dropped. Each send now asserts
`pending` with no identity at admission, then asserts the submission settles
`accepted` at `codex:<thread>:<turn>:0` once the echo lands. Same ordinal, but
earned from `identityFor` on the echo -- the key a replay recomputes -- instead
of guessed from the turn/start response. Ablated: removing `clientId` from the
two echoes leaves both submissions `pending` and fails both assertions, so the
assertion is load-bearing and not satisfied by something incidental.

Both suites' client fixtures now advertise the capability set the desktop
renderer sends in `src/main/ipc/runtime.ts`, which is what these suites mean by
a client. The older-client settlement wait keeps its own coverage in
`src/main/runtime/rpc/methods/structured-agent-session.test.ts`.

`structured-agent-session-runtime-exit.test.ts` asserts `pending` for the same
reason; it drives the host directly, so it never took the compatibility path,
and what proves delivery there is still the turn the reacquired provider starts.

The replay suite's "without dispatching it twice" property is untouched: one
`turn/start` call, one replayed ledger row.

* fix(codex): preserve unsettled dispatch correlations

* test(codex): type the dispatch fixtures instead of asserting over them

main's new casting gate (#20367 base) flags type assertions on changed
lines. Replace them with checked types: the recording sink already
satisfies its interface, both CodexSession fixtures are now annotated and
carry real collaborators, the settlement assertion compares whole
identities, and the integration helper reads submissions through the
host's public journalSnapshot instead of its private session map.

* fix(test): merge the duplicate doubt-reasons import the merge left behind

Both sides added an import from journal-dispatch-doubt-reasons and the
merge kept both statements, which the whole-repo native plugin gate
refuses under --deny-warnings.

* test(codex): a Fast mode turn is admitted, not accepted

#20506 landed its Fast mode tests against the dispatch contract this
branch replaces: a Codex send now returns admitted and settles its
identity on the provider echo. The tier assertions the test exists for
are untouched.

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

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

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

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

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

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

* test: align settled turn status expectations

* Name settled lifecycle rows by their terminal state

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

* test: deduplicate turn lifecycle suites

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

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

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

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

* Record a turn as a first-class journal item

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

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

* Preserve observed turn end across settlement retries

* Retain turn attribution for loaded chat history

* Preserve Codex exit receipt across close retries

* Register completed turn duration reliability gate

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

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

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

* Correct turn duration gate assertion reference

* Respect authoritative unknown native chat duration

* Preserve unverifiable timing across older host upgrade

* Record final completed turn duration reliability evidence

* Fix the CI failures the merge left behind

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

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

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

* Advertise the turn-item capability on every client transport

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* Fix runtime catalog and capability expectation

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Two proven blockers in the native Codex tab contract:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* test(wire): make release checkouts race safe

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

* test(wire): harden release checkout lifecycle

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

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

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