fix(mobile): permission mode picks follow changes made on other clients - #34107
A permission mode picked on the phone for an existing thread stays in that thread's draft for good, and every later phone send carries it. So after another client changes the thread's mode, the next phone send quietly switches it back. For Claude, that switch restarts the process and ends any running Workflow or background agent.
Steps to reproduce
On the phone, pick Full access for an existing thread and send a message.
On desktop, change the thread to Auto and send.
Send another message from the phone.
Before: the phone switches the thread back to Full access, and does so again after every desktop change. After: the phone sends in Auto, the thread's current mode.
Fix
The outbox releases the composer's mode pick once a send has set that mode on the thread, or found it already set, and no other queued message for that thread carries a different mode. This is the same idea as releasing a model pick on the server's reply in thread-model-selection.ts. After that, the phone follows the thread's mode, including later changes from other clients.
A pick made after a message was queued stays until a send applies it, even when it matches the mode of an older queued message. An unsent pick still applies to the next send. The release waits for saved drafts to finish loading, so loading can't bring back an older saved pick, and the pick is kept if loading fails.
setRuntimeMode is now optimistic in client-runtime, as setModelSelection is (#31739). Once the pick is released, the composer keeps showing the applied mode until the server's shell update arrives, rather than briefly falling back to the old one.
Desktop/web has the same stuck pick. #30162, for #29632, handles it there. The one shared change here is the optimistic setRuntimeMode, which also makes web show a mode change at once.
The server half of the symptom, a mode change ending Claude's background work, is handled by #23082. This PR stops the phone causing those mode changes.
Evidence
Found on a 0.1.8 install with a long-running Claude thread used from both the iOS app and the desktop app:
The thread's first Full access turn was a phone send, right after the user picked Full access on the phone.
After that, every phone send that followed a desktop send switched the thread to Full access: 7 times over two days. Each switch restarted Claude and stopped its background tasks.
Re-picking the thread's current mode on the phone stopped the switching.
Verification
Delivery test, threadOutboxDelivery.permissions.test.ts: "keeps the composer's mode pick until a delivered send applied it last". It runs delivery against the real draft store.
A pick is released when its mode is set, and when the thread already had it. Both rows fail on main.
It is kept when the server refuses the change, and when saved drafts fail to load.
It is kept when it was picked again after a message in another mode was queued. This row fails without the queue check.
A queued message with no mode, as an MCP app sends, does not hold it.
Optimistic mode, threadCommands.test.ts: a setRuntimeMode row in the existing table that shows a change before the reply and rolls back a rejection. It fails without the change.
Existing tests:use-composer-drafts.test.ts, threadOutboxDelivery.permissions.test.ts and threadOutboxDelivery.test.ts pass, 123 of 123. threadCommands.test.ts passes, 25 of 25. vp run check:changed passes.
Not checked: a run on a device or simulator.
Three notes:
Picks stored before this update: the phone's next send still applies them, so a thread another client has moved since then switches one last time. After that the pick is released.
Queued messages: a pick waits while another queued message for the thread carries a different mode. If that message is never delivered, the pick stays, as it does on main.
A permission mode picked on the phone stayed in the thread's draft for
good, so every later phone send carried it. After another client changed
the thread's mode, the next phone send switched it back; for Claude that
restarts the process and ends running Workflows and background agents.
The reconciliation that drops a draft model pick once the live server
thread has it (pingdotgg#20886) now releases the runtime mode the same way, each
field on its own. A mode pick stays while the outbox still holds a
message for the thread sent in a different mode.

Macroscope's review found this PR requires human approval — Mobile permission-mode picks now follow changes made on other clients once local overrides match the thread. The supplied cold-start finding leaves a consequential question unresolved: whether an explicit permission pick can be lost before persisted queued messages load.
Needs human approval because:

On a cold start the outbox reads persisted messages asynchronously, so the
reconciliation could see an empty queue and release a mode pick that a
persisted message in another mode would later override. Mode picks now stay
until every persisted message has been read.

The mobile outbox now conditionally clears a composer runtime-mode pick after delivery. Thread commands also apply runtime-mode changes optimistically, with test coverage for rejection rollback.
releaseComposerDraftRuntimeMode clears a draft runtime-mode pick only when it matches the supplied mode.
Release picks after delivery synchronization apps/mobile/src/state/threadOutboxDelivery.ts, apps/mobile/src/state/threadOutboxDelivery.permissions.test.ts
After runtime-mode synchronization, delivery waits for drafts to load and checks for another queued message with a different defined runtime mode before clearing the draft pick. Tests cover clearing and retention conditions.

Summary
Apply and test optimistic runtime-mode updates packages/client-runtime/src/state/threadCommands.ts, packages/client-runtime/src/state/threadCommands.test.ts
The setRuntimeMode wrapper optimistically updates the thread runtime mode from command input. The lifecycle test includes this action and rejection rollback.
An older queued send can clear a newer permission-mode pick, allowing a later send to use a mode changed on another client. This narrow risk needs owner awareness, and the hydration-order regression test should be added.

Replaces matching the pick against the live thread, which needed guards
for queued messages and outbox loading and still raced the shell update
after a delivery. The outbox now releases the composer's mode pick right
after a send has set that mode on the thread (or found it already set),
the way model picks are released on the server's reply. A different pick
made after the message was queued stays for its own send.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Track the pick that the queued message owns.
The composer records draft.runtimeMode ?? thread.runtimeMode in every queued message. A mode value therefore does not show whether the message carried a pick. If the user makes a new pick with that same value before delivery, this call clears the new pick. The next send then follows the thread mode rather than the user's unsent selection. Preserve pick provenance or a draft revision at enqueue, and release only that selection. Add a regression case for a newer, same-valued pick. (raw.githubusercontent.com)

…still change the mode
A delivered send released any pick with its own mode, including a pick made
after a later queued message in another mode. That message then moved the
thread, and the next send used its mode instead of the pick. Delivery now
releases a pick only when no other queued message for the thread carries a
different mode.
setRuntimeMode is optimistic in client-runtime, as setModelSelection is, so a
released pick never falls back to the old mode before the shell update arrives.
The delivery test now checks the real draft store instead of mock calls, and
the duplicate drafts-level test is gone.

CodeRabbit's note about pick ownership at threadOutboxDelivery.ts 813-816, from its review on 8ccbde6, is fixed in 2ce4f23. Delivery now releases a pick only when no other queued message for the thread carries a different mode, so a newer pick that matches an older message's mode survives. Regression case: the queued-pair row in threadOutboxDelivery.permissions.test.ts. Details are in the reply to the matching Codex thread.

A pick made before saved drafts finished loading could be released into an
empty draft, which deletes it; the load then brought back the older saved
draft with its old mode and text. Delivery now waits for drafts to load
before releasing, and keeps the pick if loading fails.
