Jinwoo Hong 8b2a5e45f1 Re-land Claude per-account folders (#24434, #26405) with the upgrade and proxy fixes (#26801)
* Revert "Revert Claude per-account folders (#24434, #26405) before release (#26638)"

This reverts commit 9ca9b4e36b.

* Move the terminal daemon protocol to 44 for the re-landed claude function

v43 daemons (the revert) lack the claude account function, so new terminals must not reuse them. v42 and v43 stay attachable.

* Move the local build compatibility contract to daemon protocol 44

* Point the old-terminal test at daemon protocol 44

* Claude accounts re-land: never sign anyone out, keep proxies working, accounts mirror ~/.claude (#26769)

* Run a Claude account on System default until it has its own login

An account saved before per-account folders has no login in its folder. While System default (~/.claude, or the user's own CLAUDE_CONFIG_DIR) is signed in to the same email, the router sends every launch there and writes that choice into the pointer file, so nobody is logged out by the update. Once the account signs in to its own folder, the next launch uses it. The WSL router follows the same rule with the guest's ~/.claude.

* Refresh each Claude account folder from ~/.claude before every launch

~/.claude (or the user's own CLAUDE_CONFIG_DIR) is now the master copy. Each account folder gets its whole settings.json, including the proxy address and its key, and every .claude.json key except the login, Claude's account caches and install ids, so first-run questions are not asked again. Every other top-level entry is linked (folders) or copied (files), except Claude's per-folder daemon, jobs, live sessions, login files and throwaways. sessions is no longer shared, and an earlier link is undone.

The refresh runs before every Claude Orca starts, for each new terminal and on account switch. Orca never writes back to ~/.claude. The ledger that tracked selective sharing is gone.

* Route chat auth and unselected-account usage through the Claude router

Chats decided whether to drop inherited Anthropic auth from the selection alone, so an account running on System default lost the user's own key. They now ask the router, as terminals, AI commit messages, automations and usage already do. Usage for an unselected account is read where its launches would run. A test reads every entry point through the fallback and fails if a launch path outside the router reads the Claude selection or builds an account folder. The router's two launch errors move to their own file to keep it under the line limit.

* Show Claude account sign-in prompts only when an account cannot run

With the fallback, an account System default is signed in to already works, so:
- The one-time "Finish setting up your Claude accounts" toast is gone.
- Accounts System default covers no longer need a sign-in: no Sign in in the status bar menu or Settings, and they can be selected.
- The old-terminal banner shows only when claude in that terminal would run a different account than the selected one, and asks again after a switch. Its wording is unchanged.

The retired toast's saved flag stays in the paired-client schema so an older client's write is still accepted. The email comparison moves beside the login reader to keep the router under the line limit.

* Keep the user's shell Anthropic auth on Claude account launches

A signed-in account's launches used to drop ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN and CLAUDE_CODE_OAUTH_TOKEN from the inherited environment while ANTHROPIC_BASE_URL passed through, so a proxy set in the shell got the subscription login and answered 401. Host launches on an account now keep the shell's auth with its address, as System default does. Chats still name the account kind in a failed sign-in, now from the router rather than from whether auth was dropped.

* Share from ~/.claude only what Claude itself would seed into a new folder

The deny list missed much of Claude's runtime state, so tokens, locks and live files such as .session_ingress_token, server-sessions.json and remote-control were copied or linked over each account's own every launch. The list now mirrors the one Claude uses when it seeds a fresh config folder from ~/.claude: its runtime entries, every hidden entry, daemon files and agent memory. teams, ide, downloads and scratch are on it, so they stay per folder.

* Merge trusted folders and MCP servers into an account instead of replacing them

Each refresh replaced the account's projects and mcpServers with ~/.claude's, so folder trust and allowed tools recorded only in the account were lost, and a refresh landing between Orca's folder-trust write and Claude's start brought the trust dialog back. Both are now merged per folder path or server name: ~/.claude wins for entries it has, the account keeps the rest, and a folder trusted in the account stays trusted. Both writers take Claude's lock on the file, so the order no longer matters.

* Require the same organization before System default stands in for an account

The fallback compared emails only, so one email saved for two organizations made both accounts run on whichever organization System default was signed in to. When the saved account and System default's login both name an organization, it must now match too, on the host and in WSL, and the old-terminal banner uses the same comparison. The saved-account lookup the three checks repeated is now one helper.

* Treat v42 terminals as having the claude account function

v42 daemons shipped the same claude function and pointer path as v44, so claude in those terminals already follows the selected account. The old-terminal banner now shows only for daemons before v42 and for v43, the revert, which dropped the function.

* Fail the routing test when a new module resolves the claude binary

The census only caught code that read the Claude selection, not a new launcher that runs claude without asking the router. A second check now lists every module that resolves the claude binary or loads the Agent SDK, each with why it is routed, and fails on any new one, or on a listed one that no longer matches.

* Skip the account refresh on launches that run on System default

A launch that falls back to System default never uses the account folder, so starting a setup for it on every launch was wasted work. Account switches still set the folder up for a later sign-in.

* Give a terminal opened before the login shell's env only the account pointer

At startup, a pane could be routed before the login shell reported the user's own CLAUDE_CONFIG_DIR, so the fallback compared against ~/.claude.json instead. Until that env arrives a pane gets only the pointer, and the pointer is rewritten once it does, so claude typed there reads the right folder. The recent claude --version answer moves beside the version probe to keep the router under the line limit.

* Drop the chat-only Anthropic auth stripping and override refusal

Chats no longer drop the shell's Anthropic auth on any account, so the chat launch's override refusal and the policy's stripAuthEnv could only be reached from test fixtures. The structured auth policy is now just which login a failed sign-in names. Terminals keep their refusal, which still guards WSL launches; the failure reason stays in the shared vocabulary for older peers.

* Publish a new account state file whole

The first .claude.json write went straight to the target, so a crash mid-write could leave Claude a truncated state file. It is now written to a staged file and linked into place without replacing one Claude created meanwhile.

* Read an unselected WSL account's usage where the WSL router would run it

Usage for an unselected WSL account read its saved folder directly, so an account the guest's ~/.claude covers showed no usage, and the read bypassed the router. It now asks the WSL router, after the same check that the distro is already running.

* Keep the shell's Anthropic auth when the claude function runs an account

The claude shell function (POSIX, fish and PowerShell) unset ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN, CLAUDE_CODE_OAUTH_TOKEN, AWS_BEARER_TOKEN_BEDROCK and auth-like ANTHROPIC_CUSTOM_HEADERS before running Claude in an account folder, so a proxy set in the shell lost its key while keeping its address. It now only sets CLAUDE_CONFIG_DIR and Orca's marker, as on System default. Protocol 44 is unreleased, so no new bump; the shell-wrapper snapshots are regenerated.

* Never drop the user's Anthropic auth from a Claude launch

Orca's launches stripped ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN, CLAUDE_CODE_OAUTH_TOKEN, AWS_BEARER_TOKEN_BEDROCK and auth-like ANTHROPIC_CUSTOM_HEADERS for WSL terminals, terminal splits and through the preparation's stripAuthEnv flag, and refused a launch whose agent env set them. If the user's shell overrides the login, that is their setup: every launch now keeps it, on accounts, System default and WSL alike. The flag, the strip paths and the override refusal are gone; the refusal's reason stays in the shared vocabulary so older peers still decode it.

Orca's own process env and the claude --version probe still drop these variables: they are Orca's, not the user's launch.

* Leave out of an account's state everything Claude resets when it signs out

The .claude.json copy left out the login and keys matching cache patterns, but still carried account state such as additionalModelOptionsAnsweredAt, artifactRosterDenied, lastSeenOrgDefaultUpdatedAt and the subscription notices. The copy now leaves out the exact keys Claude resets on logout, beside the install ids, Console API key and first-token date; the cache patterns stay for account caches logout does not reset. Onboarding is still copied.

* Judge an old terminal's Claude banner by the pane's own runtime

The banner compared every old pane with the host selection and showed whenever only a WSL account was selected, so old host panes showed it with nothing to say and old WSL panes were judged by the host's account. The pane now names its runtime: a host pane is compared with the host selection, a WSL pane with its distro's selection through the WSL router, and a pane whose runtime is unknown, or with no account selected for it, stays hidden.

* Leave an account's settings file alone when only Orca's hooks differ from the default home's

* Reread a WSL account's Claude state only when the file changes

* Move tests merged from main onto the account-only Claude auth policy

Jinwoo Hong 9ca9b4e36b Revert Claude per-account folders (#24434, #26405) before release (#26638)
Users with a saved Claude account were signed out of every Claude feature in Orca until they signed in again, and proxy setups (API key plus ANTHROPIC_BASE_URL) got 401s after signing in. Reverting before release to rework the upgrade path. The terminal daemon protocol moves forward to 43 so dev builds' v42 daemons with the claude function are not reused; v41 and v42 stay attachable. Nothing is deleted: per-account folders are left unused and the old saved-account store was never touched.

Brennan Benson 5252884a9c Native chat: say when Codex is signed out or the agent isn't installed, without disabling Send (#25666)
* fix(native-chat): disable Send for unavailable agents

* test: update sign-in copy expectations

* fix: show automatic chat availability only on Send

* fix: keep signed-out evidence when a live session lists models

* refactor: split Send availability presentation and tests

* refactor(native-chat): keep the sign-in verdict on the catalog's failure record

The probe's "signed out" / "CLI missing" verdict now lives on the account's
existing model-catalog failure record instead of two extra maps, with the
failure TTL as its only lifetime:

- Only the probe sets or clears the verdict; a chat's own model listing
  (which works while signed out) never clears or renews it. An aged-out
  verdict makes the next read re-probe, however fresh the catalog.
- A healthy fresh catalog is no longer re-probed every 30 s; it keeps the
  normal 10 min fresh window. A Claude start refused as signed out ages the
  catalog so the next read re-probes.
- A waiting picker again answers from whichever catalog lands first and never
  waits on a probe. A read that still owes the probe's verdict says so, and the
  composer waits for it once with the new optional waitForAvailability param.
- The open-time start-failure line and its transcript row are hidden only
  while Send is disabled for the same reason; otherwise they show as before.
- A host verdict lifetime longer than the client's hold is clamped, not
  dropped. The catalog read watches only the account settings and the paired
  host's contact instead of every store write.

* fix(native-chat): one send-gate rule, and a missing CLI as its own failure

- The sign-in/CLI verdict is gated once where the session hands it to the
  composer: while a turn runs it neither shows nor refuses, so a follow-up
  queues as before; goal mode is held by the same gate. The start-failure line
  and row hide only while that same value is up.
- A start whose CLI was never found (a direct spawn's ENOENT, or the one a
  provider supervisor reports) is now a `cliMissing` failure with the disabled
  Send's sentence, instead of a generic "couldn't start" beside it. An older
  client shows the host's sentence for the new kind.
- Signed-out words for a slash command keep "Run /x again".
- The Claude catalog reads its models only from the reply to its own
  list_models request, never from the initialize reply.
- The Codex probe lists models while its account check runs; a signed-out
  verdict still wins.
- The missing-executable check moves to provider-process, out of native chat.

* test(native-chat): signed-out command failures name the command to run again

* fix(native-chat): probe the Codex home a launch would read

- Before the catalog probe's read-only app-server reads Orca's shared Codex
  home, it runs the same sync a launch and the usage poll run, so a
  `codex login` made in ~/.codex is seen at once instead of leaving
  "Run codex login" up until something else re-syncs (forever on a headless
  host). Per-account homes are left alone.
- A "no account" answer counts as signed out only when the home's auth.json is
  absent or holds no credential; one caught mid-write by a token refresh, or
  holding a credential, is unknown.

* test(codex-accounts): type the node:os mock with a type import

* fix(native-chat): keep the sign-in verdict until a newer answer replaces it

- No gap while signed out: the host serves an aged verdict while the probe that
  re-derives it runs, and the composer never clears its last answer before a
  read; only an answer without a verdict, an error, lost contact or an account
  change does. Send stays disabled with its reason through every re-check.
- After sign-in the stale "isn't signed in" start-failure line stays hidden:
  a probe that found the account fine now says so (`accountVerified`), and the
  line shows only when the host has no answer at all.
- A Claude start refused as signed out, or any start whose CLI was never
  found, is recorded as that home's verdict, and the chat reads it once when
  that start failure arrives.
- The re-probe mark is read only where the catalog read starts its probe, so a
  Codex chat's own picker no longer re-lists for it on every read.
- Choosing an account or signing in again in Accounts settings re-derives the
  verdict at the next read; the account key now compares settings by value.
- A re-read that brings an identical catalog keeps the option state, so focus
  re-reads re-render nothing.

* fix(native-chat): Codex's signed-out words name only the step that unblocks this chat

A chat is pinned to the Codex home it started in, so choosing another account
in Codex Accounts settings never unblocks it. The system-account sentence now
says only to run `codex login`, in every locale.

* refactor(native-chat): give an account's sign-in status its own owner

The sign-in verdict lived inside the model catalog's failure records, so
the store needed guards for who wrote a failure, which listing may clear
it, and whether a verdict was served while re-probing. Each guard fixed one
way a chat's own listing or an older probe overwrote the account's answer.

The answer now lives in AgentAccountStatuses: one in-memory, capped status
per account home (ready, not signed in, or CLI missing). Only the
session-less probe, a refused start and an account change write it. A
blocked answer older than 30 s, or one an account change marked, makes the
next read start the probe whatever else is listing, and it is served until
that probe answers. Older evidence never replaces newer. The catalog's
failure code is main's again, and agent-model-catalog-failures.ts is gone.

The wire carries one optional `availability` field in place of
`unavailable` and `accountVerified`. The renderer holds its answer per
host, agent and chat, re-reads only on that agent's account inputs, and
re-reads on a timer only while blocked. After an account change, Send
stays disabled with the previous words until the re-probe answers, then
changes once. Account switches and re-sign-ins mark the status before the
settings change a chat's read follows.

* fix(native-chat): re-derive the sign-in answer after an account change mid-probe, and back off while blocked

Round-4 review findings on the account status owner:

- An account switch or re-sign-in made while a probe was running left the
  old answer up for up to 30 s: the next read joined that probe, whose
  answer was then dropped as older than the change. A read now chains
  exactly one fresh probe after a probe that began before the change.
- Removing the selected Claude account swapped another sign-in into the
  shared config dir without marking the answer; it now marks it first.
- Evidence was ordered by wall-clock time, so a clock that stepped back
  froze a blocked answer. It is now ordered by a sequence and aged on a
  monotonic clock; a negative age reads as due.
- A chat left open while signed out started a CLI probe every 30 s.
  Probes that keep finding the same block now space out (30 s, 60 s,
  2 min, 4 min, then every 5 min), carried to the client as recheckInMs.
  An account change or a different refusal starts the hold over.
- The renderer dropped no settled wait from its leave set; it now does.
- A failed Claude probe logged its whole stdout, which now includes the
  initialize reply naming the account. Control replies are dropped from
  the log and the failure message.
- The account services take the status re-check as an injected
  onSignInChanged hook instead of importing the native-chat store.
- Imports moved below file headers; comments no longer say "ready"
  means re-checked after the failure.

* test(claude-accounts): say why the runtime-auth fakes are cast where the hook was added

* fix(native-chat): type the held-answer handle as the account status

* fix(native-chat): re-check a block when someone returns, and catch an account change during a home's first probe

Round-5 review findings:

- After a chat sat blocked for a few minutes, the backoff made every
  read wait out a hold of up to 5 minutes, so someone who ran `/login`
  or `codex login` and came back still saw Send disabled for minutes.
  The backoff now applies only to the client's own timer read, which
  it marks with an optional `scheduledRecheck` param. A read from
  someone looking (window focus, the pane becoming visible, a new chat,
  a start failure) re-probes once the block is older than 30 s. The
  param is sent only on that timer, which only a blocked `availability`
  answer arms, so a host that predates the param never receives it.
- An account change made during a home's first probe marked nothing,
  because only existing statuses were marked, so the old account's
  answer was written as current. Each agent's last account change is
  now one sequence number that every status and running probe is
  compared against; statuses are no longer mutated in place.
- Removing an account that nothing had selected no longer re-checks.

* refactor(native-chat): keep the sign-in and missing-CLI words in their own module

Main's retry wording pushed the failure-words table past its line budget.

* refactor(native-chat): build the structured chat's view session in the view-state module

Main's send-reveal work brought NativeChatStructuredSession.tsx and the
session controller to their line budgets.

* fix(native-chat): keep a stated start line hidden through a running turn, and re-probe an account changed mid first probe

- A chat whose open-time start failed signed out had that line hidden
  while the host said the same. When a new signed-out answer landed
  during a running turn, the line came back for the whole turn: the
  hide read Send's gate, which a running turn suspends. The hide now
  reads the host's answer itself (blocked for the same reason, or
  ready); Send's gate still steps aside while a turn runs. Both are
  views of the one answer the session holds.
- An account change during a home's first probe dropped that probe's
  answer but left nothing to re-check the new account, and the picker's
  reply said no probe was pending, so the chat stayed unknown until the
  catalog aged out. A read now chains one fresh probe whenever the
  running probe began before the change, and its reply says that probe
  is still owed so the client asks once more for its verdict.
- The client's timer read no longer carries `scheduledRecheck`. The
  timer already fires only when the host's backed-off `recheckInMs`
  says, which is past the 30 s after which any read re-probes, and
  every answer re-arms it. One fewer strict-schema param.

* build(cli): typecheck the missing-executable check the provider process now imports

Main's #25753 added managed-provider-process.ts to the CLI project, which
imports this PR's provider-executable-missing.ts.

* fix(native-chat): disable Send with the fix when Claude or Codex is signed out or missing

What you see: in a native Claude or Codex chat whose CLI is signed out, or not installed on the
computer running the chat, Send is disabled and its tooltip (hover or keyboard focus) says how to
fix it, in words that match the account ("Codex isn't signed in. Run `codex login`.", "This
Claude account isn't signed in. Sign in again in Claude Accounts settings.", "Claude isn't
installed on the computer running this chat."). A message refused after sending gets the same
words. On desktop the open-time "Chat could not be started" line, its Retry and its transcript row
no longer repeat these two reasons, unless a message of yours is still waiting on that start.
An unknown answer never disables Send, and while a turn runs Send stays Stop and Enter queues.

How: the host's existing session-less model-catalog probe also says why no chat can start.
Claude's probe child sends initialize before list_models and applies the rule chat start already
uses (token source none with no API key); Codex's probe asks account/read beside model/list; a
spawn that finds no executable is "CLI missing". The probe's failure record in the catalog store
carries that reason, and every catalog reply carries it as an optional `unavailable` field. Only
a probe writes or clears it: a live chat's own listing (which a signed-out Codex still answers)
never does. It lasts the store's 30 s failure lifetime; after that the next read starts or joins
the probe, serving the held reason meanwhile, and only a read that already asks to wait gets the
probe's answer. A change to the managed-account settings expires it. Before probing the shared
Codex mirror home, the probe runs the same sync a launch does. The renderer keeps the latest
answer until the next one replaces it, and only while blocked re-reads on window focus and when
the chat gains focus. No status store, timers or new request params.

* fix(native-chat): no picker loading while Send re-checks a sign-in, and plain keyboard focus on the disabled Send

A chat whose account is signed out and has no model list no longer shows the model picker as
loading each time it re-checks the sign-in after 30 s: the re-check is for Send, so a reply that
already carries the verdict ends the picker's wait. The disabled Send's wrapper takes keyboard
focus (so its tooltip opens) without becoming a second button; the inner button keeps its label.
Trims tests that repeated rules other tests already prove.

* fix(native-chat): lift the Send gate whenever Stop shows, including while a queued card is about to send

The composer shows Stop while the host's queue is about to send its next card, but the sign-in
gate stayed on in that window, so Enter was refused with no message.

* fix(native-chat): never disable Send for a sign-in or missing-CLI verdict; show a dismissible notice instead

The host's pre-send check can be wrong while the chat would work (saved
Arguments it never sees, project settings it can't read, gateways that
accept a signed-out Codex), and a disabled Send left no way past it.

- Delete the Send gate: the composer, Enter and goal mode no longer read
  the verdict, and the Send tooltip reason and focusable wrapper go back
  to main.
- Show Codex not-signed-in and Claude/Codex not-installed as one entry in
  the chat's existing notice card. Dismissed per verdict; shows again
  when the verdict changes or clears and returns; steps aside when the
  failed start (launch line or latest failed-start row) says the same.
- Claude: drop the probe's signed-out verdict (initialize-on-probe stdin,
  request-id filtering, control-reply log scrubbing). The chat start's
  refusal, with its account kind, is the only Claude sign-in signal.
  Missing-CLI from the probe stays.
- Restore the failed-start line and transcript row for these causes
  (no more hiding on desktop) and drop the chat-root focus re-check; a
  window-focus re-read stays while a notice is showing.

* fix(native-chat): re-check the notice's reason after a chat starts, keep a signed-out Codex's model list

Review round 1 of the notice rework.

- A chat that proves its start (at acquire, or on its later "started"
  event) marks the catalog's held reason for that account due, so the
  next read re-probes instead of trusting it until the TTL; the chat
  re-reads when a turn starts or ends while a notice shows.
- The Codex probe keeps a model list it got beside a signed-out reason,
  so a gateway user with a wrong verdict keeps the picker list.
- Failure records move to their own module; an expired failure with no
  reason is dropped, and expiry drops reason-less failures.
- Notice: any verdict change resets the dismissal; signed-out is
  Codex-only; the say-once rule ignores a failed start a turn has run
  past.
- Missing-CLI copy: "{{agent}} wasn't found on the computer running this
  chat. Install it, or check its Command in Settings → Agents." (6
  locales).

* fix(native-chat): only an acquiring start re-checks the catalog reason; drop the unreachable Claude filter

Review round 2 of the notice rework.

- A re-attach to a live child proved nothing new, so only an attach that
  acquired a child which proved its start marks the reason due.
- Reword: a start proves the program exists; for a Codex sign-in it only
  prompts an earlier re-check.
- Drop the notice's Claude signed-out filter: no host sends that verdict.
- Tests: a re-attach does not notify; a turn ending re-reads once more.

* fix(native-chat): never newly show a catalog reason the host is still re-checking

After signing in to Codex, a new chat flashed the old "isn't signed in"
notice for about half a second: past its 30 s lifetime the host answers a
plain read with the held reason while its probe re-checks. A chat now
adopts such a reason only when it already shows it; otherwise the joined
read's answer decides.

* test(native-chat): follow main's harness and the clearer Claude sign-in words after the merge

* test(native-chat): run the start-proof catalog test in the Node runtime project with the other SQLite host tests

Brennan Benson 8fdad2a3af fix(claude): activate account profiles and remove credential replay (Step 4 of 4) (#24434)
Each saved Claude account now runs in its own CLAUDE_CONFIG_DIR folder, so Claude renews each login itself and switching no longer replays a copied credential. A claude shell function routes every launch to the selected account; the terminal daemon protocol moves to 42 so new terminals get it. After updating, each saved account signs in once: typed claude shows Claude's own sign-in, old terminals show an in-app banner, chats and the status-bar menu offer Sign in, and a one-time toast explains it. Orca prints nothing into terminals.

8464b151c7 Claude account profiles: dormant routing and consumers (Step 2 of 4) (#24351)
* feat(claude): add dormant profile setup and history sharing

* fix(claude): make profile setup one gated, typed, fail-safe entry

Review round 1 of the dormant profile setup found that the pieces could
be called without their safety checks, that one failed write or an
unreadable bookkeeping file could silently stop sharing for good, and
that Windows prompt history could bring back history the user cleared.

- One entry, provisionClaudeAccountProfile: the profile gate (namespace,
  no linked components, outside ~/.claude and ~/.config/claude, and an
  ownership marker beside the home naming the account and target) runs
  first and refuses before creating anything; then history sharing,
  config provisioning, and the hook install after the settings merge.
  Results come back per surface with closed warning codes instead of
  message text.
- The sharing ledger is keyed by surface name, records a value only
  after its write succeeded, and an unreadable ledger starts empty and
  is rewritten instead of blocking every surface.
- The profile state file goes through the same locked writer as folder
  trust (Claude's <file>.lock plus the in-process queue), generalized as
  updateClaudeGlobalConfig. Onboarding and trust are still applied when
  the personal state file is unreadable.
- WSL descriptors build guest POSIX paths; the state-file path style
  follows the injected platform.
- Orca's managed statusLine has one owner in a profile: the settings
  merge never shares it, a user's own statusLine is shared over it, and
  the profile installer follows the default home's slot so a default
  opt-out reaches every profile. remove() takes the same destination;
  the remote installer cannot accept one.
- Prompt history compares file identity (bigint dev+ino) on every
  platform, never drains the shared file into itself, drains retained
  copies in generation order, never reuses a stale cursor, and on Windows
  keeps a replaced default's old copy aside instead of replaying it.
  Directory merges keep going past a failed entry.

* fix(claude): share the user's own hooks and keep merged history whole

A user's own Claude hooks in ~/.claude (notifications, formatters) did
not run under a managed account, because the whole hooks key stayed
private. They are now shared like any other settings key: Orca's own
hook entries and its managed statusLine are stripped from both the
personal value and the profile's current value before the per-key
ledger comparison, so they never travel through the merge and never make
the key look user-owned. Orca entries already in the profile are kept on
write, and the profile hook installer adds them on top as before.

Prompt history: merged bytes that lack a final newline are terminated,
so Claude's next record no longer fuses onto the last merged line. When
a CLI rewrote the profile's history file (old records plus new), only
the lines past the part it shares with the default history are added,
instead of the whole file again.

* fix(claude): close review round 2 gaps in profile setup

Hooks and statusLine sharing:
- When ~/.claude holds only Orca's hook entries, the user's shared hooks
  now read as an empty value instead of a missing key. Removing the
  user's last own hook in ~/.claude therefore reaches profiles that
  never edited it, and deleting the only shared hook inside a profile
  stays deleted.
- A custom statusLine Orca shared, and the profile never edited, goes
  away when the default home drops it. When a shared custom line
  replaced Orca's line in a profile, the profile's statusline marker is
  dropped so Orca's line comes back once the default returns to it; a
  profile that opted out stays opted out. No other key gains deletion.
- install/remove/getStatus with a profile directory refuse when it is
  the default home, or its settings.json resolves to the default one,
  instead of editing System Default's hooks and opt-out state.
- The profile statusline rule reads the default settings under the
  userHome passed to the setup entry, not os.homedir().

Profile state and ownership:
- A malformed `projects` value skips only folder trust (new warning
  code trust-refused); onboarding and shared keys still apply.
- The ownership marker stores only host-local facts (account, runtime,
  distro). The execution host id is the caller's view of the host, so
  it stays in the in-memory descriptor and is not compared.

Prompt history interruption paths:
- With no cursor yet, a retained copy starts past the bytes it shares
  with the default history, so an interrupted share no longer replays
  the whole history.
- A retained name for the shared file itself is removed with its cursor
  instead of lingering until a later scrub makes it look new.
- The Windows link record is read three-state: unreadable stops the
  share instead of reading as "no link". If the record cannot be
  written after linking, the fresh link is undone.
- An unreadable retained copy is reported and no longer blocks linking.

* build(cli): list the new Claude hook modules in the CLI project

hook-service.ts and hook-settings.ts are compiled into the packaged CLI
project, which lists every file explicitly. The statusline policy and
profile destination modules they now import were missing, so the CLI
typecheck failed with TS6307. The CLI still loads hook-service through
the existing managed-agent-hook-controls build entry, which bundles
both modules; neither imports electron.

* fix(claude): close review round 3 regressions in profile setup

- A profile whose hooks hold only Orca's entries and that sharing never
  recorded is no longer treated as a user edit, so the user's first own
  hook in ~/.claude reaches it (for example when the profile was set up
  before ~/.claude had any hooks).
- A retained prompt-history file is removed as a second name for the
  shared file only when the default history does not itself link to it;
  otherwise it holds the only copy and is kept.
- Default-home checks compare file identity: the profile hook
  destination check uses device and inode, and the profile/default
  separation check resolves on-disk case, so a case-only alias of
  ~/.claude is refused on case-insensitive filesystems.
- A test pins that an unreadable leftover session tree no longer blocks
  linking.

* fix(claude): let shared keys leave a profile when ~/.claude drops them

QA found that removing a setting from ~/.claude never reached a managed
account: deleting the whole `hooks` block left the user's hook running
there. Only statusLine followed the default away.

Every shared key now follows the same rule through the existing per-key
ledger: when a key disappears from ~/.claude/settings.json (or
mcpServers/theme from the personal state file), it is removed from the
profile if the profile still holds exactly what Orca last shared. A
value changed inside the account is kept. Keys Orca never shared,
including denylisted ones, are never touched. Deleting the whole hooks
block removes the user's shared hooks and keeps Orca's own entries. A
missing source counts as empty; an unreadable source removes nothing.

* feat(claude): add dormant profile routing and account consumers

* fix(claude): drop the dormant profile selection RPC; clients negotiate by capability

Restores the inline mobile allowlist so its source-scan guard sees every
accounts.* method again, and the generated params catalog to generator order.

* fix(claude): guard the claude shell function and honour a hand-exported config dir

The function is defined only in a routed pane where claude is a real
executable (the codex function's guard), re-reads the pointer only while
CLAUDE_CONFIG_DIR is unset or still Orca's injected twin, accepts Git Bash
drive paths, and starts on its own line after the fish/PowerShell codex text.

* fix(claude): spawn-time profile env, total account listing, setup at lifecycle triggers

Round-1 review fixes for the dormant profile routing:
- Panes get the selected profile's CLAUDE_CONFIG_DIR plus an Orca twin at
  spawn, so nested shells and scripts inherit the account; System Default
  injects nothing and its home is the inherited CLAUDE_CONFIG_DIR.
- An absent routing owner is System Default, never a throw; AI Vault and
  session-search scans receive profile roots from their parent, and the
  capability is advertised only where an owner is installed.
- Account listing never throws: per-account readiness, a stale pointer is
  republished in the background and reported on the snapshot.
- Profiles are set up at select and startup; a launch only sets up one that
  never was, and a worker fault on a prepared profile is a warning. The
  Claude version probe is cached per binary identity.
- Pre-trust goes through the existing deadline- and realpath-guarded writer
  against the launch env's profile config.
- Skill discovery keeps a caller's Claude root and a broken Claude selection
  no longer fails other providers.
- The durable record carries a provider-neutral launchAccountHome, read
  through one helper by the launch fallback and the model catalog.

* test(claude): pin the version-probe cache, launch-account record and temp-home readers

* test(claude): pin dormant bash rc text alongside fish and PowerShell

* test(claude): read the fish launch init without a nullable index

* fix(claude): withdraw the profile pointer when a selection cannot be published

A pointer left naming the previous account would launch it silently; a
missing pointer makes the claude function refuse visibly. A newer selection
that raced the failed one keeps its pointer.

* fix(claude): read the fish profile pointer with read -z for fish older than 3.4

Shell tests skip system config and abort unless claude resolves to the fake.

* fix(claude): only the newest publish withdraws the pointer; total config dir lookup

- An overtaken publish that fails leaves the newer selection's pointer.
- The runtime config dir falls back to the legacy home for an unresolvable
  account or a WSL target, so skill roots never fail for other providers.
- WSL guest reader roots merge verbatim, never realpathed on this thread.
- History readers include ~/.claude, where step-1 setup pools profile history.
- System Default ignores a config dir an outer Orca injected (twin-marked).

* fix(claude): System Default launches and probes use the structured create resolver

A Claude agent-env CLAUDE_CONFIG_DIR the create path stored is now the home
the launch pins and the model probe accepts.

* test(claude): type the System Default launch record as an agent-session record

* fix(claude): install profile hook scripts under the setup job's home

A worker thread's os.homedir() ignores its own env, so the hook and
statusline scripts now go under the home the job names. The worker test pins
the process HOME to a sentinel, refuses to run unless the worker sees it, and
asserts nothing lands there.

* test(claude): skip shell cases whose shell the runner lacks

* fix(claude): remove env vars in the PowerShell claude function instead of setting null

On .NET 9+ (pwsh 7.5+) SetEnvironmentVariable with $null creates an empty
variable, so stripped auth vars reached claude as empty strings and the
restore left CLAUDE_CONFIG_DIR empty in the user's session.

* fix(claude): give plain fish tabs the claude function through the codex hand-off

Main now gives a plain fish tab Orca's codex function through a vendor_conf.d
snippet instead of a -C init. The claude function only rode the -C path, so a
plain fish tab would not re-read the account selection per invocation once
profiles are on. Define it at the first prompt beside codex; it stays empty
while the profile gate is off.

* fix(claude): share personal rules, themes, workflows and keybindings into account profiles

A managed account launches Claude with its own config folder, so user-level
rules/, custom themes/ (which a shared `custom:<slug>` theme points at),
personal workflows/ and keybindings.json silently stopped applying. Link the
three directories like skills and commands, and copy keybindings.json with the
same edit-preserving ledger as CLAUDE.md. routines/ stays unshared: routines
belong to the claude.ai account and the folder holds per-run state.

* test(claude): wait for the running child to read its account before switching

The test switched the selection after a fixed 20 ms, so under load the backgrounded claude
had not yet read the pointer and picked up the new account. The stand-in now marks when it has
started, and the test waits for that mark (bounded) before switching.

* fix(claude): import the personal CLAUDE.md into account profiles instead of copying it

Claude also loads ~/.claude/CLAUDE.md as a parent folder's memory for any project under home,
so a copied account CLAUDE.md made every such session read the user's instructions twice
(checked live with Claude 2.1.288). An @~/.claude/CLAUDE.md import resolves to the same real
file, which Claude loads once from home, from projects under home and from folders outside it.

* refactor(claude): simplify account profile setup toward the prior art

- Windows keeps each account's history private; drop the hardlink, link
  record and conflict-copy machinery that only Windows reached.
- Share hooks and statusLine as ordinary settings keys: Orca writes the
  same entries into every folder, so the installer finds them present.
  Drops the Orca-entry carve-out, the per-profile statusline follow
  logic and its marker.
- Unreadable ledger is just an empty ledger.
- Share from the user's own CLAUDE_CONFIG_DIR when they set one (marked
  so Orca's injected value is never mistaken for it), and refuse a
  profile at or around it.
- Pin the one canonical profile path spelling in a test.

* refactor(claude): route launches through one account router, superset-shaped

Replace the routing service, owner interface, setup worker thread, reader-root
merging, persisted launch account and capability string with one
ClaudeProfileRouter: the pointer is written first and setup runs best-effort
after it (superset's order); a missing pointer means System default.

The claude shell function re-reads the pointer on every launch, refuses only
a selected account whose folder is missing, and prints a note when the user's
own CLAUDE_CONFIG_DIR overrides the selected account in that terminal.

Still dormant: claudeProfileRoutingEnabled() is false.

* test(claude): type router test settings instead of casting

* fix(claude): run account setup on a worker thread, never Electron main

publish() writes the pointer and starts setup in the background, so neither
startup nor an account switch blocks on a history merge. Each setup runs in a
one-shot worker (the profile-state backup worker's pattern); one setup per
account at a time, reused by later requests. A launch waits only for a folder
that was never set up, and refuses with a clear message if that setup fails.

* fix(claude): do not await the synchronous pointer publish

* test(claude): give the routing launch test the merged resolver deps and handle shape

* fix(claude-accounts): dedupe merged prompt history, drop drained copies, link setup folders by path

- Prompt-history drain appends only lines the shared file lacks, so a purge never re-adds lines.
- A set-aside history copy whose saved offset reaches its end is deleted on the next run.
- Setup folders link to the default home's own entry, not its resolved target.
- The profile gate and folder creation run once, in provisionClaudeAccountProfile.
- installHooks receives only configDir; drop a duplicate test key that fails CI.

* fix(claude-accounts): refuse a routed resume whose transcript is in another account; zsh claude function; setup timeout

- With account routing, a chat resume checks its transcript is in the launch folder; a missing one
  with a stored leaf refuses with historyInOtherAccount instead of starting fresh.
- The launch folder of a selected account comes from prepareLaunch(); the resolver stays for System default.
- zsh panes get the claude function like bash, fish and PowerShell (empty while routing is off).
- The setup worker is terminated after 60 s so a later launch can retry.
- Document that the setup marker means setup started, not finished.

* fix(claude-accounts): refuse a routed resume only when the transcript is found in another folder

A transcript found in no known folder keeps the old stored-leaf resume.

* fix(claude-accounts): record installed hooks as Orca-shared; skip symlink tests on Windows

After Orca installs its hooks into an account, record the account's hooks in
the settings ledger so a later run can still bring the user's own hooks in.
Tests that create real symlinks now skip on Windows.

* fix(claude-accounts): trim the which-account file in the PowerShell claude function

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

* test(claude-accounts): spell the user's own config folder as an absolute path on every platform

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

* test(claude): skip the POSIX-only WSL profile test on Windows

A WSL profile's data root is a POSIX path, so building one from a Windows
temp dir fails the absolute-path check there.

* fix(claude): check the transcript before the account-switch recheck when no router is installed

Keeps the switched-off path identical to main: the recheck stays the last await.

Brennan Benson 923ef7cff1 fix(native-chat): refuse a Command that can't run instead of silently running the stock CLI (#25667)
* fix(native-chat): honor custom Claude and Codex launch commands

* fix(native-chat): sync launch failure localization catalogs

* feat(native-chat): run Settings → Agents → Command as the native chat program

Native chat ignored the Command setting, so a user who pointed it at a
custom Claude or Codex build still got the stock CLI. The host now reads
the Command per acquisition and per model-catalog probe, resolves it on the
execution host as a program (an absolute path, ~ path, or a name on PATH),
and spawns it with the normal structured arguments. A set Command that is
not a runnable program refuses the start with a new agentCommandNotRunnable
failure that names the setting; it never falls back to the stock CLI.

* fix(native-chat): find a configured Claude Command on the launch PATH; clearer copy

A Claude Command given as a bare name was looked up on Orca's own PATH,
not the PATH the Claude child launches with (login shell plus Settings →
Agents environment), so a name only that environment provides was refused.
Codex already resolved against its launch environment. Claude now reads
its launch env first and resolves a configured name against its PATH and
home; the stock lookup with no Command is unchanged.

The failure copy now states the rule (a program path or name, no
arguments or variables) and names the Settings control (Reset). The
catalog fingerprint doc notes that the program is not keyed, so a chat on
an older program keeps refreshing the shared entry until it ends.

* fix(native-chat): one PATH key for the Claude lookup and the child on Windows

On Windows, an inherited `Path` and a Settings → Agents env `PATH` both
reached the Claude child. The configured-program lookup read the first
inserted twin (inherited), while Node's child_process keeps the
lexicographically first (`PATH`, the user's), so a bare-name Command found
only on the Settings PATH was refused.

The Claude launch env now drops inherited case-twins of the overlay's
variables (the rule the structured shell env already applies), so the
lookup and the child read one PATH. pathEnvOf follows Node's win32 key
rule, and Codex's lookup uses it too, so both agents read PATH one way.
es/fr/ja copy now says the Command must be, as the English does.

* fix(native-chat): refuse a Command that can't run instead of running the stock CLI

A saved Settings → Agents → Command that did not resolve to a program (a
command line such as `codex --profile work`, `FOO=1 claude` or `npx …`, a
missing or relative path, a non-executable file) silently ran the stock
Claude/Codex in native chat and its model-catalog probe. The user's choice
was ignored with no sign of it.

A set Command that does not resolve now refuses the start with a new
agentCommandNotRunnable failure naming the setting, beside the existing
Retry; the catalog probe refuses the same way and never lists the stock
CLI. A blank Command keeps the stock lookup. On Windows a resolved file
without a spawnable extension (.exe/.com/.cmd/.bat) refuses too, instead
of failing to spawn with no word about the setting.

* chore(native-chat): correct comments that say native chat ignores the Command

After #25721 native chat runs a runnable Command, and this PR refuses one it can't run; four comments still said the Command applies to terminal launches only. The pre-spawn test fixture also drops the saved value from its error message, matching the resolver.

Brennan Benson e813fa5819 feat(native-chat): keep a message a Stop took back on screen, with one stop row after it (#25051)
* refactor(native-chat): derive the queue's pause from Stop and Resume journal rows

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* feat(native-chat): keep a message a Stop took back on screen, with one stop row after it

A Stop that took back a message before the agent started it used to remove the
message from the transcript and paste its text back into the sender's composer.
Other devices just lost it, and with the message gone there was nowhere for a
stop row to sit, so it either landed under the previous finished turn or was
left out.

The message now stays where it was sent, on every client, followed by one row,
"Stopped before the agent started" (one row after several taken back together).
A message whose turn had opened stays in that turn, whose "Interrupted" header
already says it was stopped. A queued card's hand-off is still held by the card.
Nothing the host recorded refills the composer any more. Text this client's own
Stop took before the host ever had it still comes back, and only into an empty
composer.

Derived from facts the journal already holds (the rejected submission's
cancelled verdict and its user item); nothing new is stored or sent.

* fix(native-chat): one stop row per stopped send, drawn where the Stop took it, and nothing lost

- A message this window's Stop took before the host had it, which the composer
  cannot take (it holds text or images, or no composer shows the chat), now stays
  in the outbox as not sent, on its Retry, instead of vanishing.
- A Codex send whose turn opened but was never echoed belongs to that turn: its
  interrupted end is the stop, so no second row is drawn. A send taken back after
  a later turn started still gets its own row.
- A steer the Stop took back stays in the turn it joined, with no row of its own.
- A queued send taken back before its hand-over is drawn after the turn it waited
  behind, not inside it.
- The conversation outline the host serves still leaves out sends a Stop took
  back, and the rail gives them no tick, so what the host publishes is unchanged.
- The row is drawn as the Stop's own status rows are, and never folds behind a
  settled turn on a host that states no turn scopes.

* fix(native-chat): draw a stopped follow-up after the turn that opened while it waited

A follow-up sent just before the agent opened its turn, then stopped, drew its
"Stopped before the agent started" row above that turn's own "Cancellation
requested." whenever the turn was expanded. A send a Stop took back is now drawn
after the rest of every turn it waited on: the one it was accepted behind, and
any that opened after it and before the Stop took it back.

Also corrects the stoppedBeforeStart doc to what sets it.

* fix(native-chat): place a stopped send by journal order, not by turn start time

The turn a stopped send waited on was picked by comparing the turn's start time
with when the Stop took the send back. A Codex resume rewrites every finished
turn's start time to Codex's whole seconds, so after a restart (or a child
respawn) a turn opened for a later send could read as started first, and the
stopped send dropped below that whole later exchange. A turn is now waited on
when something sent before the stopped send opened it, read from the journal's
own order only. Covered end to end through a restart whose resume reports
whole-second start times.

* test(native-chat): pin a stopped send held behind the first send's answer

A second send made while Codex still held the first send's turn/start answer,
then a Stop: the first turn opens after the second was accepted and streams after
the Stop. The stopped second send and its row are drawn after that turn's output,
never between the turn's header and its output. Fails on the two earlier
placement rules. The restart case moves into the same file.

* docs(native-chat): say why the pre-echo anchor still compares times

* docs(native-chat): mark the pre-echo anchor's time compare temporary (STA-9337)

* docs(native-chat): say the placement rule reads journal position, not send time

* fix(native-chat): keep sends a Stop took back in the order they were sent

Two sends queued during /compact, the first handed over and the second not,
then a Stop that took both back: the handed-over one sat at its handover row and
the other at its acceptance, so the second drew above the first. Among sends a
Stop took back, a later-sent one is now drawn no earlier than just after an
earlier one. Sent order is submittedAt, the host's accept time and the order
every client already keeps submissions in, because a client never sees a
handed-over send's acceptance position (STA-9337).

* fix(native-chat): draw a stopped send below everything sent before it

A send a Stop took back that was never handed over could still draw above an
earlier send's whole exchange when that earlier send was not itself taken back:
three queued during /compact, the first ran and finished, the second was left in
doubt, and the Stop took back only the third. A stopped send is now drawn no
earlier than the latest loaded row of anything sent before it, and the turns it
waited on are read from that point, so the earlier exchange stays above it.

* fix(native-chat): count a turn opened by the floor row as one the stopped send waited on

When the latest row sent before a stopped send was itself a turn's opener, that
turn compared equal to the floor and was not counted, so the stopped send landed
inside the earlier send's exchange: two queued during /compact, the first handed
over and streaming, then a Stop took back the second. A turn whose opener sits at
or before that point now counts, and the send draws after the whole exchange.

* feat(native-chat): publish each submission's journal positions

A client never learned where in the journal a send was accepted or taken back,
so drawing a stopped send had to guess from its own row and from clocks, and the
guesses misfired after restarts. Each projected submission now carries
`submittedSequence` (its submission row) and `resolvedSequence` (the dispatch row
that resolved it; absent while pending): two optional fields, computed on every
fold from rows already stored, never stored themselves. Older clients ignore
them. The failure-fact schema moves to its own module to keep the journal schema
file within its size limit.

* fix(native-chat): place a stopped send by the journal row that took it back

Hosts now publish where each submission and its resolving row sit in the journal (cherry-picked from #25073). The projection places a send withdrawn before it started at that row, keeps stopped sends in their published submission order, and falls back to the send's own row on hosts that publish neither.

* test(native-chat): pin a submission's resolved position on the provider-echo accept path

Also say which rows can resolve a submission, and that the submission schema, not the shared type, omits acceptedSequence.

(cherry picked from commit 58a1ade504)

* fix(native-chat): keep the previous placement rules for a host that publishes no positions

On a host from before the published journal positions, a stopped send is again drawn after the latest row of anything sent before it, as before the switch, so it no longer draws above the earlier exchange. Temporary until a host version floor. Also pins the published row against tied accept times.

* perf(native-chat): place stopped sends in one pass, and skip it in chats with none

The message projection runs on every streaming commit. It now builds turn anchors, the item lookup and the older-host floor only when the chat has a send a Stop took back, and places each such send with a binary search over the turns' furthest rows instead of rescanning every item per send. Draws are unchanged.

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

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

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

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

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

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

* test(native-chat): phone draws the same from merged frames as from a fresh snapshot

A long chat whose last send never opened and was taken back at the child's
exit, right after a send made while a Stop was ending the turn before it.
From every subscribe point, at every later frame and with frames that carry
one to three rows, the phone's list built from merged frames must equal the
list built from a fresh snapshot of the same journal.

* test(native-chat): widen the merged-vs-snapshot guard to content, long chats and the phone hooks

The guard compared row ids and turn bars only, never left the phone's first
window, put each row's writer fence on every batch, and stopped at the fold.
It now:
- compares each row's content, so a phone that kept an earlier revision of an
  answer or a status fails it;
- adds a chat longer than the phone first loads, compared from the fresh
  page's first user row on (a turn whose user row the page cut off is keyed
  differently there);
- sends batches at the subscriber's fence and a fresh snapshot when the fence
  moves, as the host's attach does;
- writes the send made while stopping while the turn still runs, adds the
  provider's echo of each send, and a status row the provider drops;
- adds a hooks test: a phone that sent the never-opened message itself, holding
  its echo and reading the host's Stopping from the status feed, shows the same
  list after every frame as a phone that opened the chat fresh then.

* test(native-chat): pin the stop row to every frame from the one that took the send back

Both guards compared a merged phone with a fresh one, so a list bug they
shared passed, including one that held the stop row back until the next send.
Both now check, at every frame from the take-back on, that the list itself
shows the stop row: the data test through the list's own turn disclosure, the
hooks test on the live and the fresh phone.

Also:
- the send made while stopping is written after the stopped turn's end, as
  the QA journal shows, and while the turn still runs, as a second case;
- the long chat revises and drops a status near its end, inside the window;
- each phone reduces its own copy of every frame;
- Stopping is checked on the never-opened send's own Stop;
- the headers say what neither guard covers;
- the mobile production typecheck leaves *.test-fixture.ts to the tests'
  program, as it does tests, since these fixtures import desktop host code.

* test(native-chat): check the stop row in the chat view's FlatList, through the real overlay

The hooks guard rebuilt the overlay and chat view by hand, so a memo in the
real view that held its list back until the next send passed it. The guard
now renders the real overlay and chat view from the phone's own hooks, and
checks the stop row in the FlatList's data at every frame from the one that
took the send back. It also subscribes once before the history's last
dropped status, so removals run through the real hooks too.

* test(native-chat): compare the live and fresh phone on the chat view's own FlatList

The hooks guard compared a hand-built copy of the overlay and view, so a memo
in the real ones keyed on list lengths kept stale rows past it. It now
compares, after every frame, what the real chat view hands its FlatList:
each row as its renderItem draws it, with its bar, and the footer. The
hand-built copy is gone. It also checks that the FlatList's keys never
collide and that a changed list never arrives in the same array, and the
controller stub's SAFETY note now states what the stub really provides.

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

* test(native-chat): pass the projection's options and mock the phone row's new imports after main's rejected-in-place rows

* refactor(native-chat): place a taken-back send by where the host now puts its row

#24710 moves a rejected send's row, a Stop's take-back included, to the row
that rejected it, in no turn. Draw it at that row, past the end of every turn
opened before it, and keep the send-order rule. A send whose turn opened before
the provider echoed it is claimed by that turn's record when it was sent before
the record and taken back after it, by submittedSequence, and is drawn as the
turn's opener. The steer branch goes: the host no longer says which turn a
taken-back steer joined, so it is drawn after that turn with its own row.
The older-host fallback (floor, clock compare, submittedAt order) is now gated
on submittedSequence alone and marked Temporary. resolvedSequence is gone, as
in #25073.

* test(native-chat): a turn recorded before a send was made is not the turn it opened

* test(native-chat): a message a Stop withdrew is drawn with its stop row, not hidden

#24710's tests pinned a withdrawn send as hidden, the rule this PR replaces.
Each keeps what it is about: a withdrawn copy does not hide a failed one, no
delivery notice is raised, and a message the host failed to deliver stays
hidden on the phone.

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

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

* feat(native-chat): publish the turn a withdrawn Codex send was answered into

Same change as #25073 at 93749070e4, so this stack builds on it.

* feat(native-chat): say how a withdrawn Codex send joined the turn it names

Same change as #25073 at ab2826ee18, so this stack builds on it.

* fix(native-chat): open a turn for a stopped send only when the host says it started it

A send a Stop took back after its turn opened but before Codex echoed it
is drawn as that turn's opener when the host names the turn and says the
send started it. A steer into that turn keeps its own row after the turn.
The guess from journal order and times is kept only for hosts that
publish neither field, and never hands a turn the provider resumed on its
own to a send. A page that starts inside such a turn draws the send
before the turn's first loaded row.

* test(native-chat): an echoed opener keeps its turn from a send the host says started it

* feat(native-chat): state on every rejection whether it names a turn

Same change as #25073 at e02f98add5, so this stack builds on it.

* fix(native-chat): place a stopped send from older history by journal order

A rejection written before the host named turns carries no answered turn,
though a newer host still publishes where it was sent and has moved its
row to the take-back. Such a send is matched to its turn by journal order
again, as before the host named turns; a rejection that states no turn
opens none.

* docs(native-chat): say an unreadable answered turn reads as none

Same change as #25073 at 4ab6cc431c.

* refactor(native-chat): order stopped sends without non-null assertions

One helper sorts by the published send position when every entry has it,
else by accept time, and both stopped-send sorts use it. The rule kept for
rejections written before the host named turns is labelled as kept for
good: it draws those rows exactly as before.

* docs(native-chat): say which half of the older-history turn rule is kept for good

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

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

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

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

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

* fix(mobile-chat): a send a Stop took back is not handed back to the draft

A send whose answer says a Stop withdrew it is drawn in the chat with
its stop row, so handing its text back to the composer as well showed it
twice. It reads as sent and spends its id; other rejections still go
back to the draft as main has them.

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

* fix(mobile-chat): resend a retained replay a Stop took back, under a fresh id

A retained id is keyed by the message text, so its replay cannot be told
from a new send of the same text. When the answer is a submission a Stop
withdrew, that message provably never ran, so the phone sends it once
more under a fresh id, as it already does for a withdrawn queued card.
A first answer a Stop took back still reads as sent, as on desktop.

* test(mobile-chat): count every send a withdrawn replay makes

* fix(mobile-chat): a resend a Stop took back again is not handed back to the draft

When storage fails, a resend's answer is lost and a second Stop takes
the resend back, the fall-through after a withdrawn resend returned the
text to the draft beside its stopped row. A withdrawn submission there
now reads as sent; a withdrawn queued draft still goes back. Pins the
one-resend guard and both orders of the stopped row and a resend.

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

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

* test(native-chat): draw a stopped send end to end in this PR's own Codex file

The shared turn-end settlement file went past its line limit once main's
Stop tests and the answered-turn tests met. This PR's two drawing checks
move to its own end-to-end file, leaving that file as #25073 has it.

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

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

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

* test(native-chat): restore the named Stop, turn anchor and role checks in the moved draw tests

* test(native-chat): name the Codex handle as main's opaque handle does

* test: restore the provider handle import the main merge dropped

* test: give the android live-line fixtures the stopping field

* chore: keep the session host under its line limit after the main merge

* test: follow main's card field and live-line component in the stop-withdrawn tests

* chore: keep the composer test and the phone chat view under their line limits after the main merge

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

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

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

* fix(native-chat): keep the Spanish 'Stopped before the agent started' in the one notices block; the phone parity test reads Stopping from the live line

Brennan Benson defd85a9eb feat(floating-workspace): render the floating panel through the shared workspace surface (#22302)
* docs(floating-workspace): plan structured native chat in the floating panel

* feat(floating-workspace): resolve the floating workspace so a structured session can run there

* docs(floating-workspace): plan the unification onto the shared workspace surface

* chore(floating-workspace): keep the unification plan out of the branch

* test(floating-workspace): pin the structured route on capability, not workspace kind

The host half removed the 'floating-workspace' blocker; this pin still asserted it and went red
on the merge. Floating now routes like any workspace, so with capabilities un-negotiated the
resolver answers 'runtime-capability-unknown'.

* feat(floating-workspace): resolve the floating workspace's renderer row without a worktree record

The renderer had no Worktree row for the floating id: markdown creation, tab-bar path entry,
native-chat file links, attachments and model discovery all resolve a workspace through
getKnownWorktreeById and silently fail for it. The host already answers with a synthetic row
minted from the resolved floating directory; this gives the renderer the same single seam.

- The repo slice stores the host-resolved floating directory (floatingWorkspacePath); the panel's
  existing cwd resolution now writes it there instead of panel-local state, so there is one copy.
- findKnownWorktreeById mints the shared floatingWorkspaceToWorktree row from that path, local
  host only, cached while the directory is unchanged — mirroring the folder-workspace branch it
  sits beside.
- No consumer changes needed: every row-dependent path already goes through this resolver.

* feat(tabs): scope editor and browser activation to the owning workspace

Shared editor/browser activation always wrote global selection (activeFileId,
activeBrowserTabId, activeTabType). The floating panel is an overlay above the active
workspace, and its active tab must never become global selection — the invariant
documented in agent-auto-ack-targets.ts. Group-scoped activation is a prerequisite for
rendering the floating workspace through the shared tab-group surface.

- setActiveFile and setActiveBrowserTab take an optional target workspace, mirroring
  setActiveTabType: global selection moves only when the target IS the globally active
  workspace; per-workspace state always updates. Omitted keeps legacy behavior.
- The shared tab-group activation/creation commands pass their workspace, which is a
  no-op for the main surface (hidden surfaces are inert, so commands only fire on the
  active workspace) and confines floating activation to floating state.
- Terminal setActiveTab was already owner-scoped; now pinned by test.

* refactor(tab-group): separate the workspace drag scope and group tree from main-window chrome

Preparation for hosting the floating workspace on the shared surface, whose shell owns its own
titlebar tab strip and cannot mount the main chrome:

- WorkspaceTabDragLayer: the one dnd-kit scope for a workspace's strips and tree, extracted from
  TabGroupSplitLayout as a render-prop layer so a host can put shell-owned chrome (a titlebar
  strip) inside the same drag scope as the tree.
- TabGroupSplitNodeTree: the chrome-free recursive group tree, with an explicit tabStrip
  composition point on TabGroupPanel ('attached' keeps today's per-group strip; 'external' hosts
  render no per-group strip at all — a hidden one would register duplicate drag sortables).
- WorkspacePaneOverlayLayers: the retained pane hosts extracted from WorktreeSplitSurface so any
  tree host mounts the same pane lifecycle stack.
- TerminalPaneOverlayLayer gains ownsNativeChatToggleShortcut, following the existing rule that
  only one live workspace registers the chord.

TabGroupSplitLayout and WorktreeSplitSurface recompose these parts; the main surface's DOM is
unchanged.

* feat(floating-workspace): decide the panel's emptiness and layout atomically

An empty floating workspace has no tab-group layout at all (the slice starts empty and
hydration skips tab-less workspaces), while the shared group tree requires one. This model
resolves the two together: the panel shows its empty state exactly until the first tab exists,
and mounts the tree only with a layout plus a live focused group (stored focus, else the group
with an active tab, else the first group — matching the shell chrome's focused-group policy).

* feat(floating-workspace): render the floating panel through the shared workspace surface

The panel previously projected exactly one tab group and hand-rendered its panes, so any tab
that left that group — 'Move Tab to Split' creates a second group — stayed alive in state but
vanished from the panel. The body now mounts the shared group tree and retained pane overlay
stack for the floating workspace id, so every group renders, splits work, and structured chat
finally has a floating surface.

- One drag scope: WorkspaceTabDragLayer wraps the titlebar strip AND the body tree, so exactly
  one DndContext owns floating tab drag; strip drops reorder, body-edge drops split. The
  floating-only FloatingWorkspaceTabDragContext is deleted.
- The titlebar keeps the panel's single TabBar, now fed by the shared per-group workspace model
  of the focused group (tabStrip='external' keeps per-group strips out of the shell), with
  workspace-scoped activation commands so global selection never moves.
- Panes render through WorkspacePaneOverlayLayers: terminals gate on the resolved cwd and a
  settled viewport exactly as before; browser guests ride the shared retention layer; agent
  session tabs appear in the strip and render through the structured overlay.
- The empty state renders exactly until the first resolvable tab exists (stale unified entries
  still show it), per the atomic layout/emptiness model.
- Deleted: the single-group projection, the hand-written pane maps, FloatingBrowserSlot, and
  the floating pane-handle registry.

Known behavior deltas, both narrowing floating onto main-workspace semantics: Cmd/Ctrl+W with
panel (not terminal) focus closes the active tab rather than one pane of a multi-pane tab, and
a pane-owned close of the last tab no longer arms the panel focus reclaim (strip and shortcut
closes still do).

* test: re-register moved pane-ownership sites with the extraction

The retained overlay stack moved into WorkspacePaneOverlayLayers and the floating chrome model
became a guest-paint consumer; the structured-pane layering pin and the browser-guest retention
census both name files, so they follow the seam.

* fix(floating-workspace): mount the shared group tree in a flex frame so panes own their height

The tree's nodes size themselves as flex items, and the floating shell mounted
them in a block container, so every group body — and every pane anchored to
one via anchor-size() — measured 0px tall. Wrap the tree and overlay layers in
the same 'absolute inset-0 flex' frame the worktree split surface uses, record
the host contract on the tree, pin the frame in the panel's element-tree test,
and add a real-renderer e2e spec that measures group-body and pane boxes for
the single-group and split layouts (jsdom computes no layout, which is how the
0px regression passed 50k tests).

* fix(runtime): import the floating worktree minting the structured create path calls

floatingWorkspaceToResolvedWorktree called floatingWorkspaceToWorktree without
importing it. The module is @ts-nocheck (mechanically split runtime), so tsc
never saw the missing import and it only failed at call time — the structured
createSupport probe for the floating workspace threw a ReferenceError. Add the
import and a test that runs the real method, which fails on the missing import
where the typechecker cannot.

* fix(browser-pane): resolve floating and folder workspace paths in notebook navigation

navigateBrowserPageToUrl looked the workspace up in allWorktrees(), which has
no row for folder or floating workspaces, so their notebook navigations ran
with an undefined workspace path. Use getKnownWorktreeById, the same resolver
every other consumer was moved to.

* fix(tabs): keep a workspace's tab selection out of the main window's global selection

* refactor(floating-workspace): launch and close panes like every other workspace

* refactor(tab-group): let the surface that mounts tab groups describe its own chrome

* refactor(floating-workspace): render the floating panel through the shared workspace surface

* fix(floating-workspace): resolve the floating directory once on the host, and keep the controls' inset

* test(floating-workspace): pin the unified floating panel against the shared surface

* fix(floating-workspace): read the floating directory's paths through the app environment

The runtime now resolves the floating directory itself, and the headless
runtime has no Electron app, so the Electron path lookup threw there.

* fix(floating-workspace): keep the main window's frame and shortcuts out of the floating panel

The shared layout drew the main window's 4px titlebar band and sidebar seam
inside the floating panel, and the chat-view toggle fired in every workspace
on screen, so one key press flipped the main window's tab and the panel's.

* fix(floating-workspace): close floating tabs without taking over the main window

An unsaved floating note's save prompt made the floating panel the main
window's active worktree, and never appeared on a fresh launch because the
workbench that owns the prompt was not mounted. The prompt now shows a
floating note in the panel, and the workbench mounts while the panel holds
tabs.

Every close path now reads the same captured emptied-workspace reaction, so a
floating pane closing itself, its shell exiting, a group close, and an unsaved
note close all keep the panel's keyboard ownership, as a tab close already did.

* test(tab-group): pin that a dirty editor close carries its emptied reaction

* refactor(tabs): one rule for when a selection moves the main window's selection

Opening a file kept a floating-only exception while every other writer checked
whether the tab's workspace is the active one. Every writer now asks the same
question, so opening a file in a background worktree no longer points the main
window's editor selection into that worktree.

* refactor(floating-workspace): drop what the shared surface left unused

The terminal pane's imperative close handle lost its last consumer when the
floating panel stopped keeping its own pane registry, and the floating and
folder workspaces built the same lineage-free resolved worktree twice.

* test(floating-workspace): type test fixtures without casts and drop the removed pane ref

* fix(floating-workspace): keep panel focus when a close lands after the panel emptied

Saving the last floating note closes it after an awaited write, so the panel
could render empty before the close armed its keyboard reclaim, leaving the
intent armed with nothing left to consume it. The panel now re-checks whenever
the intent arms as well as when its tab count changes.

A pinned tab's confirmation took focus before the close read panel ownership;
the dispatcher now captures it before any prompt.

* refactor(floating-workspace): finish what the shared surface left behind

- The floating panel no longer accepts AI vault session drops: a session
  cannot resume into it, and its window-level drop handler fired beside the
  main window's.
- The last global-selection writers that spelled the active-workspace check
  inline now use the shared rule.
- Remove the save-dialog hook and item counter the old floating body used, and
  correct comments that said the workbench only mounts once a workspace exists.

* fix(floating-workspace): keep a floating leaf detach from changing the main window's tab type

* fix(floating-workspace): give floating chats their workspace identity and directory

* fix(floating-workspace): read one visibility fact for chat attention and auto-ack

* docs(floating-workspace): correct comments the shared surface made stale

* fix(agent-session): pin the folder a session launched in; floating chats resume there or refuse

* fix(native-chat): resolve a floating chat's file links, images and skills in its pinned folder

* fix(agent-session): open a floating chat's terminal handoff in its pinned folder

* fix(agent-session): surface refusal text on chat open, require the launch-directory rule, and keep bookkeeping from gating a launch

* fix(floating-workspace): wait for a floating chat's pinned folder and read panel visibility from the store

* test(floating-workspace): assert the toggle event without a cast

* fix(native-chat): show why a chat could not be opened instead of dropping the host's refusal

* fix(readme): point translations at tracked media

* fix(floating-workspace): retain split surface with an empty focused group

* docs(tabs): describe workspace-owned activation accurately

* fix(floating-workspace): finish the main merge and name the pin a launch directory

Port what the merge left on main's newer shapes:
- The floating chat's "folder is gone" refusal becomes a typed reason,
  launchFolderMissing, worded like every other start refusal (copy, desktop
  words, five translations). Older clients drop the unknown reason and show
  the code's generic words.
- The PR's launch-folder tests run on main's journal-database record store;
  the attach-level case is a row in the pre-spawn refusal table.
- Tests main added since the PR's base learn the PR's close-queue settling,
  workspace-scoped notebook lookup and tab-stamped chat host.
- Move the store's visible-tab-index reads into the tab table, so the record
  store stays under the line cap with the pin writer in it.
- Drop a duplicate Worktree import the merge left in a @ts-nocheck file.

Rename the persisted field, the status summary field and the renderer slice
from workspacePath to launchDirectory: it records the folder a session first
launched in, not its workspace's path, and it has not shipped yet.

* Fix floating chat visibility, closes, and directory pinning

* fix(i18n): drop the floating save dialog's strings with the dialog

The floating panel now closes through the shared unsaved-changes prompt, so
its own dialog's six strings had no caller and failed the runtime-catalog
check.

* fix(native-chat): pin floating founders and retain pinned editors

* test: align auto-ack fixtures with unified tab visibility

* test: give the forget-status attach fixture a location

Attach now reads params.location to decide whether a new record is a floating founder, so the partial fixture needs the location real attach params always carry.

* test: type the forget-status attach fixture instead of casting it

The cast tripped the changed-code type-assertion gate.

* fix(native-chat): read a floating chat's model defaults in the folder it was created in

The model picker read the floating setting's current folder, so a chat
pinned to another folder could show that folder's project default.

* test(cross-version): give the stub host the record store the catalog read now checks

* test(claude): give main's thinking-display launch stub the store shape the resolver takes

Brennan BensonandClaude d60f999f94 fix(native-chat): turn facts come from the turn record, and /compact is a message the chat sends (#23059)
* 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.

* 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.

* 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.

* fix(native-chat): the conversation outlives its agent

Opening a chat no longer starts its agent. A conversation is reached through one host
accessor that opens its journal at rest, and a send is what starts the agent, through
the delivery loop. One idle sweep, every five minutes, stops an agent that has been
quiet for thirty minutes and owes no work, then drops an open journal handle that is
only a cache. Its record, tab, status row and readers stay.

- hold and release are no-ops; hold still builds the host for shipped mobile builds.
- The holders, the holds, the release clock and the exit respawn are deleted.
- Options, the model list, the goal and the context meter answer at rest; a model pick
  at rest is recorded as intent for the next start.
- Compact, rewind, clear and goal changes start the agent first. A send does too when
  a rewind is still in doubt after the conversation opens.
- Orchestration routes mail and group addresses on ownership (the record plus the chat
  tab), not on whether the process runs. An open dispatch keeps its worker running.
- The restart continuation is a send; Resume all holds each slot until the message is
  handed over or rejected.
- A read error never replaces a loaded transcript, and shows the host's own words.

* 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 restart offer ends when the chat's agent starts again

The offer used to end only when the chat's newest user message changed,
because opening a chat started its agent and that start could not be told
apart from real activity. Opening a chat starts nothing now, so the host
reads the fact it already publishes: a chat's status row goes from not
host-owned to host-owned exactly when its agent is started. At that edge the
offer and any failure record for the chat are withdrawn, unless the start is
a resume action's own (its continuation is the oldest undelivered message).

A continuation and a message racing to be first are decided at acceptance:
the continuation is refused, quietly and with nothing filed, when any other
message was accepted since the restart. A failed continuation start leaves
the offer retryable, and each resume action sends its own message id.

Deleted: the newest-user-message comparison, its journal reader, the
continuation filter, and the failure ledger's own "answered by the chat"
check. The marker still carries its message id for one release, so the
previous build can read it.

* fix(runtime): end a transcript stream when its client unsubscribes

Desktop: the IPC subscription controller was dropped as soon as the streaming
handler returned, which for most streams is right after it binds. A later
runtime:unsubscribe then found nothing to abort, so the host kept the subscriber
and derived and sent every publish to a channel no one listened to. The controller
now lives until the renderer unsubscribes, resubscribes the same id, or goes away.

Mobile: disposing an agentSession.subscribe stream now sends agentSession.unsubscribe
with the stream's frame id, so the host ends that subscriber and leaves a sibling
stream on the same socket running. The direct path now passes the frame id the relay
path already passed.

* 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): one fact ends a restart offer: the chat moved on since the restart

The offer is live while no other message has been accepted in the chat since the
restart and its agent has not proved a start since. The offer list, the resume's
reservation check and the continuation's acceptance check all read that one fact,
so a message whose start then failed withdraws the offer too, and a stale click
finds nothing to act on.

The fact is read off the conversation's open handle, which the restart closed, so
it is retired durably whenever it may have changed: a message accepted, a start
proven. A close and reopen within the same run therefore cannot bring the offer
back. A continuation rejected before it reached the agent does not count, so a
retry after a failed start still runs.

Deleted: the quit-time gate on withdrawal, which changed nothing because the
withdrawal and the quit's own offer write share one queue; the per-action
"withdrawn" flag and the separate acceptance check it paired with.

* test(native-chat): an older build reads the restart offer this build records

The offer lives in a file the previous release reads after a downgrade. Pin that
against the pinned release's own capsule, and run the lane when the marker or the
capsule changes.

* fix(native-chat): read a restart offer against where the journal stood when it was taken

"Since the restart" was read off the conversation's open handle, which the idle
sweep closes: after a reopen, a message the user had already sent looked older
than the handle and the withdrawn offer came back.

The offer now records the journal position (epoch and sequence) at the moment
it is taken, and a message accepted after that position, or a journal on another
epoch, means the chat moved on. That is derived from the journal, so it holds
across any number of closes and reopens. An older build's offer has no position;
only a start withdraws it. Because the message half is now durable, the offer is
no longer rewritten in the recovery file on every accepted message; a proven
start still writes it, since only the host that saw the start knows of it.

* test(native-chat): wait for the listing's retire write before reading the recovery file

* refactor(native-chat): every journal row states which turn it belongs to

Rows gain a turn scope stated by the write that creates them: the open root
turn, or the conversation. A queued message takes its scope from its handover.
Rows stored before scopes existed are placed on replay by the root turn open
when they were created, so no persisted state is needed for them. Rewind keeps
each retained row's scope and producer, so a subagent's row stays its own.

* fix(native-chat): keep the terminal-backed chat's read error over its local echoes

Messages winning over a read error is right for the structured chat, whose read retries and whose
messages came from the transcript. The terminal-backed view assembles its list from local echoes
too (a launch prompt, a pending send), so a failed read there showed only those bubbles and no
error. Only the structured pane now keeps messages over an error.

* fix(native-chat): a start retries the exit settlement a failed journal write left owed

An agent exit whose journal settlement write failed releases the lease latched until a retry lands.
Reopening the chat used to be that retry; with reveal now only opening the journal, nothing retried
it before the next app launch, and every send was refused. The start the send needs now runs the
retry first, where the attach would.

* 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.

* perf(native-chat): answer the owner check without opening the chat

Worktree activation calls agentSession.handoffStatus for every chat tab in the worktree, and the
answer comes from the session record alone. Reaching it through the accessor opened each resting
chat's journal (a full read, the crash-boundary write and a restored status publish), then kept it
open for the idle window. It now checks the record and the adapter's support, as before this series,
and opens nothing.

* fix(native-chat): a read waiting on the session lock opens nothing once quit began

The accessor checked for quit before queueing the open, so a read queued behind a session task ran
its open after teardown had begun and indexed a journal no teardown step would close. The check now
runs at the open itself.

* test(native-chat): pin stated turn scopes, the upcast of unscoped rows, and rewind attribution

* fix(native-chat): /compact is a message the chat sends, run as a turn of its own

The conversation command RPC now accepts /compact into the queue like any
send and answers once it is handed over. The delivery loop opens the command's
own turn, starts the provider on it, and waits for the provider's end off the
session's queue, so messages typed meanwhile are held and delivered after it,
even when it fails. It settles by re-reading the journal: a child that died
meanwhile already wrote the verdict. Stop ends the command at once. The 180 s
completion window, the unconfirmed row and the recovery of an older build's
compaction record are gone; that record no longer gates anything. On Codex the
provider turn the command opens is claimed into the command's turn.

* fix(native-chat): read a failed resume's chat before calling it retryable

Whether a failed resume is retryable is the offer's own rule: the chat has not moved on since the
restart, read from its journal. The failure list read it only for a chat already open, so once the
idle sweep closed a chat the user had moved on in, its failure showed Retry again, and the click did
nothing. The list now opens the failed chats first, as the offer list does.

* test(native-chat): type the provider event sink the settlement test reaches for

* 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.

* fix(native-chat): say the structured read keeps trying only where it does

The structured pane's "Orca keeps trying to load it" line never showed: the view state filled in an
untranslated fallback whenever the read error had no text, and the empty state prefers any message.
The view state now leaves the message out, so the structured pane shows that line and the
terminal-backed pane its own translated one. Mobile's structured lane does not resubscribe after an
error frame, so it no longer makes the claim.

* fix(native-chat): rows group under the turn their record names, not the one above them

Each row's turn is the turn its stated scope names, anchored on the entry
that opened it, or on the turn itself when the provider opened it unasked.
So /compact groups its own rows and the previous turn is untouched, a message
typed into a running turn joins it, and a provider-resumed turn folds under
its own Worked-for. A row reporting how a turn ended, an error or the
compaction separator, never folds. Desktop and mobile read the same keys; a
host that states no scope keeps today's positional grouping.

* test(native-chat): await the send's settlement instead of polling for the start

The at-rest send tests polled for the provider start with vi.waitFor's one-second default, which a
loaded machine outran. They now await the host's own settlement of the message.

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

* fix(native-chat): a restart offer resumes any time after the quit, and knows its own continuations

The continuation's message id was dated by the quit, and the ledger refuses a new id dated more than
a day back, so Resume or Retry a day after quitting was always refused (on main too). It is now
dated by the resume action.

Telling a rejected continuation from the user's own message read the operation ledger, whose rows
expire after about a day; after that a failed resume stopped being retryable. The offer now
records the continuation each action sends on its own capsule entry, bounded to the newest 16, so
the ids end with the offer. The ledger read is deleted.

* fix(native-chat): a /compact is not a request the sidebar, notifications or restart resume report

The sidebar's prompt, preview, verdict and instant, the turn-completion feed,
and the restart-resume marker read past a conversation command and its turn to
the last real request, so a /compact neither notifies nor re-dates the row,
and a command in flight is never offered as work to resume. An older client
shown a command's turn in the legacy form names the session's own agent.

* fix(orchestration): route no mail to a structured worker its orchestration released

A structured worker is routed on ownership, and a resting worker's lease is released, so ownership
held while its chat tab stayed listed. A worker the coordinator abandoned and then released, found
at rest by the release, therefore still took peer mail and @worktree: broadcasts, and each one
restarted its agent. Routing now also reads the orchestration's own resource row: once it is
released, direct mail, group addressing and worker-show's addressable answer drop the worker, as
they would a terminal worker whose terminal closed. The chat tab stays, and nothing new is stored.

* fix(native-chat): a failed retry names the user's prompt, not Orca's continuation

A resume's continuation is written to the chat before its start, so after a failed attempt the chat's
newest user message is that rejected continuation. A second failure then showed Orca's own restart
text as the chat's prompt. A retry now keeps the prompt its first failure named.

* test(native-chat): pin what a conversation command's admission refuses at rest and at handover

* test(native-chat): tests merged from the base state which turn their rows belong to

* 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(orchestration): read the released row optionally, as the authority does

worker-show's observation called the row lookup directly, which a runtime double without it threw on
and failed the structured tab-retirement release.

* chore(native-chat): one import per module and no unexplained casts in the turn-scope changes

* test(claude): pin which turn a Claude row joins, including a subagent's after the turn ends

* fix(native-chat): the status bar drops a restart offer the chat moved on from

The renderer re-read the host's restart offer only when a failed chat showed activity, so after a
message withdrew a pending offer the host answered no chats while the status bar kept counting one,
and clicking it opened nothing. The same watch now covers pending offers: a status change in an
offered chat asks the host again, once.

* fix(native-chat): a refused steer is read from the turn its handover named

The latest-request reader decided whether a refused send had joined a running turn by comparing
host clocks: its handover time against the previous turn's end. The handover row now states the
turn it delivered into, so the reader reads that instead and the clock comparison goes. A journal
written before handover rows stated a turn is scoped on replay from the turn open when each row
was written, which can differ from the clock reading only when a send and a turn's end share a
millisecond.

* fix(mobile): the native-chat controller contract carries the turn journal

The controller and overlay already pass nativeChatTurnJournal, but the
contract type never declared it, so mobile failed to typecheck.

* fix(native-chat): the live turn is the running turn, not the newest user row

A turn the provider opened on its own (a background wake, a resumed turn)
anchors on its own record, but the list still treated the newest user row
as the live turn. While such a turn ran, the settled user turn before it
lost its duration and the running turn's own rows were drawn as settled,
so its tool calls lost their live state.

nativeChatTurnMembership now answers both questions from the turn record:
each row's turn, and the live turn (the running root turn's anchor, else
the newest user row, which is also all an unscoped host has). Desktop and
mobile key liveness, the timing clock and the live status's row on it.

* test(native-chat): a turn the provider opened keeps its own clock

Pins that the local turn clock follows the live turn, so a wake after a
settled turn does not restart that turn's clock when no host durations
are recorded.

* fix(native-chat): a running turn no message opened draws its status on no row

Its live status belongs to the transcript-tail indicator alone. Once it
settles, its duration draws at its first row as before; a running turn a
message opened still draws on that message.

* 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

* test(native-chat): a roster of idle or finished children does not keep an agent awake

The sweep reads owed background work through the shared child-work liveness that upstream's
release clock adopted; a child that went idle or finished is not work the agent still owes.

* 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(orchestration): a task dispatched into a resting structured worker keeps it running

The sweep's open-dispatch check read only the worker-start dispatch that owns the worker's terminal
resource, so a task later dispatched to the same worker (orchestration dispatch --to, which writes a
dispatch with no worker row) did not count: after thirty quiet minutes the worker was stopped while
that task was open, and its coordinator read exited. Any unsettled dispatch addressed to the worker's
process incarnation now counts, derived from the existing rows.

* fix(native-chat): a command's wait ends when its child does

The delivery loop waited for a /compact only on the adapter's compaction
tracker, which learns of the child's end only on some exit paths: a Codex
exit or close, and a Claude close, never reach it. The wait then never
ended, so nothing queued behind the command was delivered again, Stop had
no child to answer through, and the tracker's leftover entry refused the
next /compact.

Every way a child ends passes endProviderChild, so the host now offers a
per-child end signal there. The loop races the tracker against it (the
dead-generation settlement has already written the command's verdict),
and on that end asks every adapter to release the command, so a later
command runs and no later provider turn is claimed into the dead one.
The adapters' own exit-time releases were unreachable (Codex) or covered
one path of several (Claude), and are removed.

The Codex RPC test harness moves to its own module so the exit can be
driven through the real adapter's connection callback.

* fix(native-chat): keep refusing sends during a command on an older host

An older host's controller still refuses a send while a conversation
command runs, so dropping the client's block turned every message typed
during /compact into a 'not sent' row with Retry there. The block stays
for hosts that do not run the command as a send-path turn, and goes only
for those that do.

The signal is one the client already holds: a host that runs /compact on
the send path states a turn scope on every journal row it writes, the
same fact turn membership uses to tell it from an older host. Both now
read it from one predicate. On an empty conversation, or one whose rows
all predate the upgrade, the signal is absent until the command's own
entry streams in, so that brief window keeps the old local refusal; no
capability or wire field is added.

* docs(native-chat): comments stop describing the hold this PR removed

Eight comments still justified orderings and teardown choices by a viewer or dispatch hold that
pinned the provider child. Nothing holds any more; the orderings stand for the binding's redrive
subscription and parked mail, and a chat's agent runs from a send until the idle sweep rests it.
Comment-only.

* 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(native-chat): a restart offer keeps the start its own continuation made

Whose start ended an offer was decided at read time, from whether the offer's continuation was
still the queued message. Once the provider refused that continuation, the child it had started
read as someone else's start, so the offer ended and its failure showed no Retry. The delivery
loop now records which queued message a start is for on the in-memory child, and the child's end
carries it; the offer counts a start as its own when that message is one of its continuations.

* fix(native-chat): a rewound turn still names the message that opened it

A Codex rewind rebuilds the epoch without submissions, so each sent message survives only under
its provider key. The kept turn records still named the submission key, so each turn anchored on
itself and its rows grouped apart from the message that opened it. The rewind now renames the
turn's opener along with the message.

* fix(native-chat): Stop ends only the command it names

Stop on a command turn abandoned whatever compaction the session had pending, so a late Stop for
an earlier /compact cancelled the one running now. The tracker now ends a command only when the
Stop names its turn, and the cancel reply reports whether it did.

* fix(native-chat): an agent gets a full idle window after its owed work ends

The sweep measured quiet only from the last journal row, so once a subagent, command, monitor or
dispatch that had outlived the window ended, the agent was stopped at the next tick. A child can
read done before the lead's wake-up turn writes anything, and stopping in that gap loses the
wake-up. The sweep now counts owed work it observes as activity, which gives the agent the full
window afterwards, as the release clock it replaced did.

* test(claude): the options-read fixture runs a live child

The fixture marked its conversation running with a hasProviderChild field the
session type does not have, so the read took the at-rest path and refused a
session with no record. It now carries a child, which is what the read checks.

* test(native-chat): host tests reach its collaborators through a typed seam

The rest-test rig and three test files read the host's private members with
Reflect.get and cast the result. The host now exposes one test-only accessor,
collaboratorsForTests(), and the subscribers class a subscriberCountForTests()
beside its existing retainedActivityCountForTests(), so the tests are checked
against the real types and the casts are gone.

* 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.

* refactor(orchestration): one owner answers a structured worker's custody

Routing, group addressing, worker-show and the idle sweep each composed their own reading of
whether orchestration still holds a structured worker, so each new obligation or retirement state
had to be added to every reader. structured-worker-custody now derives both answers from the
worker-terminal list state coordinators see in worker-list: addressable is owned and not released,
and owed work is an active custody or an unsettled task dispatched to the same incarnation. The
owner's state is read through the remote dispatch attachment too, as the terminal transfer lookup
already does. Behaviour is unchanged; a settled worker awaiting its coordinator still rests.

* refactor(orchestration): owed work is an open dispatch on the worker's incarnation

A supervised worker's own dispatch context stays open exactly while the worker is active, so the
separate active-custody branch only repeated it. Owed work is now one fact, which also states the
policy that a worker awaiting its coordinator's decision may rest, and both custody decisions are
written once at the top of the module.

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

* fix(native-chat): a restart offer knows its continuations by a tag in their id

The offer recorded each continuation id in a list on its capsule entry, capped at 16, and a running
action's id in memory. Both could disagree with the journal: past the cap an old rejected
continuation read as the chat moving on, and a crash during a retry restored the failure's older
entry, which lacked the retry's id. Each continuation id now carries a tag derived from the offer
(its teardown and chat), then the action's own part, so any continuation of this offer, queued or
rejected, is recognised from the journal row and the marker alone. The persisted list, its cap and
the in-memory action map are deleted; the agent-start withdrawal keeps an offer whose own
continuation the start was for, read against the stored marker.

* test(runtime): the legacy-worker reveal test judges its stale snapshot inside the wait

The tui-idle probe reads through readTerminal, which now awaits the structured
worker check before the PTY read, so the probe's snapshot request starts a
microtask later. vi.waitFor missed it on its first check and polled again at
50 ms, the same moment the wait's own 50 ms timeout fired. The stale snapshot
then resolved after the wait had already timed out, so the test passed without
judging it, and the rejection landed before any handler was attached. Vitest
reported that as an unhandled error and failed the shard.

Polling every 1 ms sees the request within a few ms, so the snapshot is judged
while the wait is still pending.

* fix(native-chat): a message held behind /compact is drawn where it was handed over

A message typed while /compact runs was drawn above the compaction's result, between
itself and its own answer. The reducer kept every item at the sequence and timestamp of
the row that created it, and a queued message is created at acceptance, long before the
command it waits behind writes its result. The phone orders by that sequence and the
desktop by that timestamp, so both put the message first.

A queued message now takes its position from its handover row, the same row that already
states its turn scope. Everything the agent did before the handover, a command it waited
behind included, draws above it. This holds for every held message, not only /compact's,
and needs no client change: every client, older builds included, reads the position the
host publishes. A live batch already carries the item when its dispatch row lands, and
history pages cut the reduced timeline by sequence, so paging stays contiguous.

* fix(native-chat): a phone's send during /compact answers without waiting out the compaction

A client that predates accepted-send replies, which is every phone build, has its send
reply held until the host hands the message over. A message sent during /compact is not
handed over until the compaction ends, so the phone's 15 s request timeout fired first
and showed the message as unconfirmed.

That wait now also ends once the message is queued behind a running command. This is
read from the journal's running turn and needs no new state. Every other wait still
ends at the handover: behind a starting child or an ordinary turn, and for restart
resume, the command front door and orchestration, which keep the plain handover point.

* perf(native-chat): a rewind places provider items with one pass over the merged rows

A Codex rewind gives each provider item the old epoch never held the turn record for its
provider turn. It found that record by scanning every merged row, restoring each row's
body, once per provider item. That is quadratic, and it runs on the host's main thread
up to the journal's 10,000-row cap, twice per rewind. A rewind record written before
rows carried their scope holds no scope for any provider item, so it paid the full cost.

The merge now indexes turn records by provider turn id once, keeping the first match as
the scan did, and each provider item looks its record up.

* 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 message waiting behind /compact is drawn after it until it is sent

A message sent while /compact runs is placed where it was handed over. It was still
drawn where it was accepted until then. /compact writes its result one step before the
handover, so for that step the waiting message sat above the compaction's separator.

A message the host accepted but has not handed over is not part of the conversation
yet, so both clients now draw it after everything the agent has done. The shared
projection moves it to the end, which is the order the phone draws. The desktop ranks
it with the other not-yet-sent rows, after the streaming preview. At handover it takes
its place from its handover row, which is also after the separator, so it never
appears above the compaction it waited for.

* fix(native-chat): the idle sweep reads owed work every tick

Owed work counted as activity, but the sweep read it only once the idle window had elapsed, so it
refreshed the clock at most once a window. Work that ended just before the next read left the
agent to be stopped at that read, moments after the work ended, which is the gap the refresh was
meant to cover. The sweep now reads owed work on every tick for a started agent, so the window
always runs from the last tick that saw work owed.

* fix(native-chat): a continuation handed to the agent stays sent

The offer read its own continuation as not reaching the agent while its dispatch was pending, which
also covered one already handed over and still unanswered. When the wait for that answer ended first,
the failure it filed read as retryable, and a retry sent a second continuation to an agent that may
have acted on the first. Only a continuation still queued, or rejected, is now read as unsent.

* 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

* fix(native-chat): a command ends only by its own provider answer or its child's end

Stop no longer settles a conversation command. It interrupts it like any turn,
and when the provider cannot take that (Codex has not opened the command's turn
yet, or Claude refuses the interrupt) it stops the child, whose dead-generation
settlement writes the verdict.

The pending command now lives on the provider child's own session instead of an
adapter-wide map keyed by session, so it dies with the child and nothing has to
release it. Claude's /compact is sent under a uuid the slot records, and only a
root result naming that input (or naming none) ends it; its outcome is read with
the ordinary result reading, so a stopped /compact is a cancellation.

* fix(native-chat): a command's settle answers its message before ending its turn

The two writes are not one batch. Writing the message's answer first means a
crash between them leaves a running command turn, which the stale-turn sweep
already settles, instead of an ended turn whose message reads as in flight
forever. The settle now writes only while the command turn is still running.

* fix(native-chat): "Worked for" counts from the handover, not the send

A message held behind /compact, or behind a cold start, used to count the wait
as the agent's work, although its row is drawn at the handover. Every handed-over
submission's turn, the command's own included, now starts at the handover row's
instant, falling back to the send time for a host that recorded none.

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

* test(native-chat): the interrupted create's own retry continues again

The merge of main's lease-latch fix replaced that test's retry of the interrupted create, under its
own operation id, with a fresh start whose result nothing read. That fresh start passes with the
released-reservation continuation deleted, so the case the fix exists for went untested. The retry
and its assertion are main's again.

* docs(native-chat): three comments that still had views starting agents

A start with nothing queued now comes from a command, goal change or rewind; an interrupted compaction
left alone would refuse every send, so no agent would ever start to finish it; and a current host
raises the unattached read refusal only once quit began, with the attach window belonging to an older
host.

* 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): a second Stop on a command ends its child; one compaction verdict for every provider

A Stop's note now names itself in its key, so a later Stop on a command still
running reads, from the journal, that the provider was already asked and never
answered, and stops the child instead of interrupting again. Nothing is held in
memory for it.

Adds the rule both translators will read a compaction's end by: only a
compaction the provider reported is a success; none after Orca's interrupt is a
cancellation; anything else is a failure. A real Claude capture, pinned as a
fixture, is why: a stopped /compact ends in the same success result as a
finished one.

* test(native-chat): a reader's open settles the turn a failed exit settlement left running

An exit whose settlement write failed leaves its turn running in the open journal. PR 1's open now
settles it, and this pins the two reads that reach it here: a reader reopening a chat the idle
sweep closed, and a read that opens the chat before the restart restore reaches it.

* test(native-chat): the view-start test's starting window outlasts two subscriptions on a loaded runner

A subscription reads the conversation before it returns, so under load the two views took longer
than the create child's 300 ms start, which then exited before the test checked that it had not.
The child now takes a second to fail.

* 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.

* refactor(native-chat): the provider's translator ends a command's turn; the loop holds no command state

A conversation command is now a turn of the provider child's own journal
pipeline. The adapter-wide tracker, its promise and the loop's settle step are
gone.

- Codex: the translator claims the provider turn that carries the command, scopes
  its rows to the command's turn, and writes the command's end in the same batch
  that settles that turn. Codex's own compaction marker is the success row.
- Claude: the command's turn is the translator's open turn until the result that
  answers the /compact input ends it. The command's own frames, such as the
  continuation summary, its echo and "Compaction canceled.", draw nothing.
- Both read the end with the one compaction rule: success needs the provider's
  report of the compaction; none after Orca's interrupt is a cancellation.
- The message resolves at the provider's receipt, as any send does: the Codex
  ack, or the Claude slash-command waiter on its result. The host writes a
  command's end only when the provider never took it.
- The delivery loop stops while a command's turn runs, and every journal commit
  re-wakes it through the session's serialize, so an end that lands while a step
  decides to stop is never lost. A child that ends first is settled with it.

* test(native-chat): pin a command's end to real /compact frames and to each path it threads

The captured /compact frames drive the Claude translator's command turn: a
finished compaction ends as a success with only the separator drawn; a stopped
one ends as a cancellation with no failure row, and the next send answers in its
own turn; a result naming another input ends nothing. The command's end is
checked at each point the ordinary result path threads through: the reopen latch
after a failure, the settling of a child still working, the context facts the
result reports, and the provider's own error row.

On the host: a message held behind a command is handed over when the command
ends just as the loop stops for it, a refused command settles as a failure and
the loop moves on, and a Claude child that exits mid-command settles the command
and hands what waited to a fresh child.

* test(native-chat): tests merged from the base state which turn their rows belong to

* refactor(native-chat): drop the child-end waiter nothing waits on

A command no longer waits for its child here: its turn ends from the provider's frames or from
that child's settlement, and the delivery loop is woken by the commit. The waiter and its test
were left from the earlier shape.

* fix(native-chat): a command holds the queue only while its child runs it

The delivery loop stopped whenever the journal showed a command's turn running. When the
command's child ended and its settlement could not be written, that turn stayed running with
no child to end it, and the loop's gate kept it from ever starting the next child, which is
what settles a gone generation's leftovers. Every later send was held for good, and Stop had
no child to end.

The gate now holds only while the conversation has a child: with none, the command belongs to
a gone generation, and the loop's start settles it like any turn a dead child left running.

* fix(native-chat): a Claude /compact succeeds only on its compaction boundary

The command's evidence counted Claude's `compact_result: 'success'` status as the compaction
done. That status comes before the boundary that replaces the history, so a Stop landing
between the two read as a finished compaction even though no boundary was ever written. Only
the boundary now counts, as the rule for both providers states; the capture's finished
compaction carries one, so it still reads as a success.

* fix(native-chat): a Claude child's exit says why the turn it ended stopped

When a Claude child exited mid-/compact, the command showed "Worked for 0s" and no reason. The
child's translator ends its open turn the moment the exit is reported, stamped with the exit's
instant, so by the time the exit settlement ran nothing was running. The settlement recognises a
turn the exit already ended by that same instant, but the Claude lifecycle event dropped it on the
way to the host, which then used its own clock, matched nothing, and wrote no row. When the clocks
did agree, the row was scoped to the running turn, of which there was none, so it landed outside
the turn it explained.

The exit's instant now reaches the host, and the exit row belongs to the turn the exit ended:
still running, or ended by the translator at that instant.

* fix(native-chat): a message waiting behind /compact draws below its live activity

A message sent while /compact runs waits on the host until the command ends. Both clients moved
it to the end of the transcript rows, but the running turn's live activity line ("Compacting the
conversation") draws after every row, so the waiting message sat between the command and its own
live status.

A row that is queued, and not what the live turn is for, now draws after that live activity: on
desktop outside the transcript window, below the activity line; on the phone in the list footer,
below the live status. A message whose own start is pending still draws above the activity that
start reports.

* fix(native-chat): only a running command holds a message below its live activity

A message is accepted, then handed over a moment later, and in between it reads as waiting. Every
message waiting behind a live turn drew below that turn's activity line, so an ordinary message
sent while the agent was working crossed below "Thinking" and jumped back up once it was handed
over, on desktop and phone. Only a conversation command's turn holds the queue on the host.

A message now waits below the live activity only while the running turn is one a command opened,
read from the entry that opened it. The phone test also typechecks, which the mobile test ratchet
requires.

* test(codex): the claim test names its notification params as a record

* test(native-chat): a read that reaches a crashed chat before the startup reconcile settles its turn

On desktop the chat on screen at relaunch reads before startup reconciles the leases, while the
dead process's lease still reads live. The open settles the turn it left running anyway, and the
restore that follows finds it settled.

* 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.

* docs(native-chat): drop the removed dispatch hold from six comments

A worker's session no longer takes a dispatch hold, and no release clock
rests a chat by visibility; the agent-launch comments, the abandon test,
the teardown test and the refusal census still said so.

* test(native-chat): rest the owner-status chat through the idle sweep, not a hold

The activation-gate test from #22808 put its chat at rest by holding and
releasing it, and passed the release-clock grace. This branch deleted both,
so the case threw before it reached its assertions. It now moves the host's
clock past the idle window and lets the sweep stop the agent and close the
conversation, then asserts the same owner answer and activation gate.

* fix(native-chat): show the structured pane's retrying line when a read fails

The read transport always hands the pane the host's words, so the error
state's "Orca keeps trying to load it" line, which showed only when there
were none, was never seen: the pane showed the host's text twice, as its
subtitle and on the status line under it. The structured pane now always
says its read keeps retrying, and the host's text stays on the status line.
The terminal-backed chat is unchanged.

* 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.

* fix(native-chat): a failed Codex compaction's late completion writes no turn of its own

Codex ends a failed turn with an error and then still completes it as failed.
The error settled the compaction and released its claim on the provider turn,
so the completion read that turn as an ordinary one and wrote a stray record.
The claim now lasts until the completion, which adds nothing to a command the
error already ended.

* test(native-chat): the mid-command exit case resumes its next child as a real one does

The case's fake started every child as a newly created thread with the same generation. The
store refuses a created link once the conversation has a thread, so the next child's start
failed and wrote its own error row, which landed before or after the case read the journal.
The next child now resumes the thread under its own generation, and the case reads the
journal once the waiting message is delivered, which also proves the loop moved on.

* test(native-chat): wait for a send's background start before the refusal oracle removes its store

An accepted send wakes the delivery loop, which starts the agent in the background. The oracle's teardown disposed the loop but did not wait for that start, so its lease write could create a temp file in the store directory while the directory was being removed, failing the test with ENOTEMPTY about one run in four. The teardown now drains tracked starts before it closes the journals.

* fix(native-chat): a start a message waited on gets one failure row, the delivery loop's

When a queued message's start failed, two writers could report it under the same row: the delivery loop, when the adapter settled the start without proving it, and the exit settlement, when the child's exit landed. The last one won, so the chat's row could name a different cause than the one the message was rejected with, or be written twice.

The exit settlement now writes the start's row only when no message is queued and the loop has not already recorded that start. A start for a command, goal change or rewind, with nothing queued, still gets its row from the exit.

* fix(native-chat): a /compact whose start failed says to run /compact again

The failure-words context named only /clear as a command to retry, so a
/compact whose agent failed to start read "Send your message to try again."
on its row, its rejected message and the command reply. The context now
carries any conversation command; the host derives it from the oldest
message still waiting on the provider, which is the one a failed start
fails first, and the /compact reply names it directly.

* fix(native-chat): a Codex /compact ends only on its turn's completion, below Codex's own error row

Since only turn/completed ends a Codex turn, Codex's turn-ending `error` is a row
inside the still-open command turn, and the failed completion that follows it is
the command's end: completed, outcome failure, at the completion's receipt time.
The command's own "Compaction failed" row was written on that completion too, so a
failed /compact read its reason twice.

The command turn now notes when Codex's turn-ending error for the turn it carries
was written as a row, and its end then adds no second row. A retried stream error
ends nothing and is not counted. The flag that let the error end the command and
kept the claim until the completion is gone with the error-driven end.

A test replays the captured failed compaction from the real app-server through a
claimed command turn.

* test(native-chat): main's crash-turn test states its row's turn, and a dead /compact settles on its recorded exit

Two tests the main merge brought together:
- The crash-turn test from #23456 writes a turn record through the event sink
  without options; every row here states its turn scope, and a turn record's is
  the thread.
- The /compact whose exit settlement could not be written no longer stays running
  until the next start: main now settles an open chat from the exit it recorded, so
  the command reads interrupted before the next message, which is then delivered.

* test(native-chat): main's new journal tests state each row's turn

The crash-turn, stale-turn and sink-queue tests main added wrote rows without a
turn scope, which every item write now states. Rows written inside a running
turn name that turn; the sink-queue batch and a send handed over with no live
turn name the thread.

* fix(native-chat): draw a queued turn's message after the earlier turn's rows

A message sent while A runs is written to the journal when it is sent.
When the provider queues it (Claude answers it after A), A's remaining
rows - its last tool run and its answer - are written after that
message, and the message's own turn opens only after them. Grouping put
those rows in A's turn, but the transcript still drew them in journal
order, below B's bubble and bar, where A's answer read as B's reply. This
is the residual #23671 left open.

A message that opened a turn now draws after the earlier turns' rows the
journal wrote after it, just before its own turn's rows
(nativeChatTurnDrawOrder, returned by nativeChatTurnMembership as
drawOrder). Desktop and mobile both draw in that order. A steer, and a
message that has opened no turn yet, stay where they were written. It
applies on hosts that state turn scopes and, through journal order, on
older ones.

* test(native-chat): run #23026's Stop tests against #23059's command turns

Two of #23026's tests call APIs #23059 changed, and failed after the
merge:

- codex-structured-conversation-stop: a compaction now goes through
  adapter.compact with the command run the host wrote (#23059), not a
  bare turn id, and answers with the provider's receipt. With the command
  claimed, a Stop that names no turn while the compaction's provider turn
  has not opened still interrupts nothing.
- main-agent-working-agreement: a provider row states its turn scope
  (#23059's appendItem contract); the retry and subagent rows are
  conversation-scoped.

* fix(native-chat): typecheck main's Stop and restore-grouping code against #23059

A Stop's compaction interrupt reads the narrowed requested turn, and the
restore-grouping test states whether each row reports its turn's outcome.

Brennan BensonandClaude c49388cd33 fix(native-chat): Stop is there from the moment a message is sent (#23026)
* 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): type the stalled snapshot drain without a cast

* 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.

* 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 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.

* 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): type the stalled snapshot drain without a cast

* 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`.

* 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 BensonandClaude 85067494a1 fix(native-chat): a request that failed reads as failed (#22944)
* 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.

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

* 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): type the stalled snapshot drain without a cast

* 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.

* 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(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.

* 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): 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.

Brennan BensonandClaude bfe476f922 fix(native-chat): a message is accepted, then delivered (#22821)
* 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.

* 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.

* 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 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.

* 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.

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

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

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

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

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

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

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

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

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

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

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

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

Both are narrow and both were real.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(native-chat): enforce fail-closed structured send replay

* fix(native-chat): align retry and mobile RPC contracts

* fix(native-chat): keep transient admissions retryable

* test(tab-bar): expand nested create menu in harness
