Unproven: T3 Connect / relay connections. Testing them needs a signed-in T3 Connect account, which the test setup does not use.

This no longer changes apps/server or packages/contracts, so there is no wire protocol change.

A policy call for review: before an environment's session has loaded (for example the app started while it was offline), settle, snooze and their undo are offered and can queue. The server checks the scope when a queued change is sent and refuses one this connection may not make.

Closes #24532, the remaining settle/snooze failure from #4852 (comment).

Settle and snooze fail when a thread's machine is offline, even when the thread is cached. This saves those actions on the device, shows them as waiting to sync, and sends them when the machine is back. They survive an app restart, and Undo cancels one that was never sent.

How it works

• The shared client (packages/client-runtime) does all of it, for mobile, web and desktop. A queued change keeps its command ID and a short record of the thread as the user saw it: latest run, status, item count, pending request, and its settle, un-settle, snooze and pin state with their times.
• When the environment is back and its shell is synchronized, each queued change is compared with the thread the server now reports. The change is first marked as sent in storage. Then, if the shell is still synchronized and the thread matches what the user acted on, it is sent under its stored command ID. If the thread differs, the server's state wins and the change is dropped.
• The server already answers a command ID only once, so a retry after a lost reply cannot apply twice. If a reply was lost but the change did apply, the returning shell shows it applied, and that drops the queued copy without another send.
• Nothing on the server changed, so this works against servers of any version.
• Storage is one small document: localStorage on web and desktop, a file on mobile. Replay reads the stored queue first, memory mirrors what the last read or write returned, and every change is confirmed in storage right before it is sent.
• An Undo of a change that was never sent cancels it on the device. Once it was sent, even if the reply was lost, Undo asks the server. A change that provably never left the device, because the environment had no session or the shell stopped being synchronized while the change was being marked, stays cancellable.
• Each app has one check for "may this connection settle or snooze here": yes while no session has loaded, otherwise whatever the last loaded session grants, also after a failed refresh. Other actions still need a loaded session.

Limits:

• The "did the thread change" check runs on the client, right before the send. A change landing on the server in the few milliseconds between the synchronized shell and the command is not caught. An online click has a wider window.
• A rename, a tag change or a visit on another device does not count as a change. A new run, new output, a new approval or question, and a settle, un-settle, snooze or pin elsewhere do, even when it was undone again.
• One undone decision is not noticed: a thread snoozed and then woken on another device looks the same as before, because the thread list data carries no wake time. A queued change for it still applies.
• While a settle is waiting to sync, that thread cannot also be snoozed; the snooze fails with the normal not-connected message.
• Another open tab picks up a change queued in this tab when it reconnects. If two tabs send the same change, it carries one command ID, so the server applies it once.
• Two tabs writing the queue in the same instant can overwrite each other, because localStorage has no cross-tab transaction. The window is one synchronous read and write.
• A change dropped because the thread changed, or because this connection may not make it, is dropped without a message, as the user docs say.

Size

This revision removes the server guard (snapshotSequence, the threadTriageVersionGuard capability, the orchestrator check and the event store filter), the IndexedDB store and the per-entry-point offline permission plumbing. The diff against main went from +2,556 / −202 in 42 files to +1,503 / −140 in 34 files.

Evidence at this head

Both runs used an isolated dev server on 0a9cd7573a with threads from the free replay provider, each with one finished turn. That was before the review fixes in 0ab8f1810b. After those, the web server-restart case was run again: two settles queued while the server process was stopped, one on a thread with snooze history, were each accepted once after the restart. At the final head 5bc9fdaacd, a settle and a snooze queued in the browser while its connection was cut were each accepted once on reconnect. The iOS and packaged macOS runs below used the current head 64b8f9022f (main merged into 5bc9fdaacd, no change to this PR's files). "Receipts" are the server's command receipts, read from a copy of its database after the run.

Web (Chromium)

The browser reaches the server through a TCP proxy that can be cut, so the server stays up while the browser is offline. The recording is sped up five times.

Thread	Offline action	After reconnect	Receipts
Lean settle	Settle	Settled	thread.settle accepted once
Lean snooze	Snooze until tomorrow	Snoozed	thread.snooze accepted once
Lean conflict	Settle, then a new message sent to it on the server	Back in the active list with the new run	none
Lean undo	Settle, then Un-settle	Active, as before	none
Lean restart	Settle while the server process was stopped, then server restarted	Settled	thread.settle accepted once

While offline, the queued rows read "Pending" and the stored queue held one entry per change. After reconnect the stored queue was empty.

web-offline-triage-lean.mp4

Android (POCO F4, dev client)

The phone's route to the server was removed while the server stayed up. The recording is sped up.

Thread	Offline action	After reconnect	Receipts
Phone settle	Settle	Settled	thread.settle accepted once
Phone snooze	Snooze until tomorrow	Snoozed	thread.snooze accepted once
Phone conflict	Settle, then a new message sent to it on the server	Back in the active list	none
Lean undo	Settle, then Undo	Active, as before	none

The app was force-stopped and started again while still offline. Both queued settles then showed "Waiting to sync", the queue file held the three changes, and a long-press on an active row offered only Settle and Snooze. After reconnect the queue file was empty.

android-offline-triage-lean.mp4

iOS Simulator (iPhone 18 Pro, iOS 27.0, dev client)

Run at 64b8f9022f. The app reaches an isolated dev server through a TCP proxy that can be cut. The recording is sped up.

Thread	Offline action	After reconnect	Receipts
iOS settle	Settle	Settled	thread.settle accepted once
iOS snooze	Snooze until tomorrow	Snoozed	thread.snooze accepted once
iOS undo	Settle, then Undo on the notice	Active, as before	none

Both queued rows showed "Waiting to sync" and no receipt existed while offline. The app was restarted while still offline and both rows still showed "Waiting to sync". The first part of the recording ends just before the sync; the second part opens on the synced list. A row with a pending settle offers Un-settle and no Snooze.

ios-offline-triage-lean.mp4

Packaged macOS desktop app (macOS 27.0.1)

Run at 64b8f9022f. The DMG was built with vp run dist:desktop:dmg:arm64 (unsigned) and run from a task folder with its own T3CODE_HOME. The dev server was added as a remote environment through a TCP proxy that can be cut. The recording is sped up.

Thread	Offline action	After reconnect	Receipts
Mac settle	Settle	Settled	thread.settle accepted once
Mac snooze	Snooze until tomorrow	Snoozed	thread.snooze accepted once
Mac undo	Settle, then Undo on the toast	Active, as before	none
Mac guard	Settle, then Snooze on the same thread	Snooze refused; after Un-settle, active as before	none

Both queued rows showed "Pending". The app was quit and launched again while still offline and both rows still showed "Pending". The refused snooze shows "Failed to snooze thread: shiv is not connected." and the settle stays queued.

Earlier evidence, from before the client-only rewrite

These runs used the earlier design (a server-side sequence guard and an IndexedDB store). They are kept as a record of the bug on main and of the earlier iOS, desktop and packaged-app runs.

Each recording tests one thing. "Receipts" are the server's command receipts, read from a copy of its database after the run. Recordings 1–6 and the retest below predate the simplification (f3ba024b49); "At the current head" re-runs the main flow on web and Android after it.

#	What it tests	Client	Commit	Result
1	The bug: settle while the environment is offline	Android app	main 5b35402623	Fails
2	Queued actions after the server shuts down with live sessions, before the session-stop fix	Android, POCO F4	5bc76a9e72	Queue, then rejected on reconnect
3	Offline settle and snooze, across an app restart	Android, POCO F4	095d8a8e61	Both sync
4	Same flow on iOS	iOS Simulator	095d8a8e61	Both sync
5	Web on plain HTTP, where Web Locks don't exist	Chromium	095d8a8e61	Both sync
6	Desktop app	macOS desktop	2d21e1f348	Both sync

1. Before: offline settle fails

• Tests: the bug in https://git.cafe/pingdotgg/t3code/issues/24532, on main.
• Client: Android app. Commit: main 5b35402623.
• Steps: environment corex-t3 disconnected, then Settle from a cached thread's menu.
• Result: "Could not settle thread. corex-t3 is not connected." The thread stays active.

before-pr.mp4

2. Before the session-stop fix: queued actions are rejected

• Tests: what happens to queued actions when the server was shut down with live provider sessions. This is the run that found the bug the session-stop change fixes.
• Client: Android, POCO F4. Commit: 5bc76a9e72, this branch before that fix.
• Steps: server stopped, settle one thread and snooze another, app restarted, server started.
• Result: both actions queue and survive the restart. On reconnect the server rejects both (receipts rejected, "changed after the client's snapshot"), because shutting down marked the sessions stopped. The threads return to the active list.

3. Android: offline settle and snooze sync after a restart

• Tests: the fix end to end, including an app restart while actions are pending.
• Client: Android, POCO F4. Commit: 095d8a8e61.
• Steps: server stopped with live sessions, settle one thread and snooze another, app force-stopped and reopened, server started.
• Result: both stay pending across the restart, then sync. Receipts accepted at sequences 223 and 224.

4. iOS: same flow

• Tests: the same flow as 3 on iOS.
• Client: iOS Simulator, iPhone 18 Pro, iOS 27.0. Commit: 095d8a8e61.
• Steps: as in 3.
• Result: both pending while offline, then both receipts accepted.

ios-offline-settle-snooze.mp4

Waiting to sync	Synced

5. Web on a plain-HTTP origin

• Tests: the IndexedDB queue on an origin that isn't a secure context, like a LAN address. The earlier Web Lock version refused to queue here.
• Client: Chromium at http://t3-insecure.test:7383 (isSecureContext false, no Web Locks). Commit: 095d8a8e61.
• Steps: server stopped, settle and snooze through the sidebar row buttons, server started.
• Result: both rows show Pending while offline, then sync.

Pending while offline	Synced

6. macOS desktop app

• Tests: the same flow in the Electron app.
• Client: vp run dev:desktop on macOS 27.0.1, not the packaged build. Commit: 2d21e1f348.
• Steps: backend stopped, settle and snooze from the sidebar, backend started.
• Result: both pending while offline, then both receipts accepted.

Pending while offline	Synced

At the current head, after the simplification

Run on corex at dbe264f659 (881b7df905 after it changes only a test; on aa82609a25, web settle-and-sync was run again and passed) against an isolated dev server with test threads only. Receipts were read from a copy of the server's database.

Case	Web, Chromium	Android, POCO F4
Settle and snooze while offline, then sync	Pass, both accepted once	Pass, both accepted once
Undo a queued settle while offline	Pass, cancelled on the device, no receipt	Not run
Reload or cold start while offline	The web app can't boot while its own server is down (same on main); the queue survived the reload and synced once the server was back	Pass: after a force-stop and reopen, both still Waiting to sync
Thread menu after a cold start offline, no session loaded	n/a	Offers Settle and Snooze only

Web: settle, snooze, and an Undo of a queued settle while offline, then sync. The reload while the server was down is cut.

web-offline-triage-simplified.mp4

Android: settle and snooze while offline, force-stop and reopen offline, then sync. The last three seconds are a screenshot taken right after, because the sync landed just after the recording stopped.

android-offline-triage-simplified.mp4

Retest before the simplification

Run on corex and shiv after the last review fixes, against isolated dev servers with free Replay (corex) or Codex (shiv) turns. Receipts were read from a copy of each server's database.

Case	Web, Chromium on plain HTTP	Android, POCO F4	iOS Simulator, iPhone 18 Pro
Settle and snooze while offline, then sync	Pass, both accepted	Pass after a real server shutdown and an app force-stop, both accepted	Pass after a force-quit, both accepted
Undo a queued settle	Pass, nothing sent	Pass, nothing sent; Un-settle from the menu also cancels	Pass, nothing sent; Un-settle also cancels
Thread changed by another client before sync	Pass, rejected ("changed after the client's snapshot"), thread back in the list	Pass, rejected, thread back in the list	Not run
Two tabs queue at once	Pass, each sent exactly once	n/a	n/a
Snooze while a settle is pending	Refused with the new message	Not offered	Not offered
Client queued for this release, server swapped to main, then back	Stays pending on main's server (nothing sent); a new offline settle there says to update the server; syncs once this release's server is back	Not run	Not run

The web runs kept the page loaded across reconnects (the connection was cut between Vite and the server, so Vite didn't reload the page). The iOS recordings from this retest are still on shiv, which was unreachable when these were uploaded.

Android, offline settle and snooze survive a server shutdown and an app force-stop, then sync. The middle of the clip, where the app showed the developer's other environments, is cut.

android-1-offline-restart.mp4

Android, Undo of a queued settle, and a thread changed by another client before sync.

android-2-sync-undo-conflict.mp4

Android, started offline: a pending settle offers only Un-settle, which cancels it.

android-3-offline-start-undo-gating.mp4

Web, Undo of a queued settle.

web-undo.mp4

Web, a thread changed by another client before sync is rejected and comes back.

web-conflict.mp4

Web, snooze while a settle is pending is refused with the new message.

web-guard.mp4

Web, two tabs queue at once and each change is sent once.

web-tabs.mp4

Web, queued for this release while the server runs main, then synced once this release's server is back.

web-mixed.mp4

Macroscope then found that offline, Un-settle and Wake now were offered on threads whose settle or snooze had already synced, and failed as not connected. 2cc00a91fb offers them offline only for a change still waiting to sync, in the web chat header and menus and the mobile thread screen, list menu and swipe actions. The offline case in threadActionMenu.logic.test.ts covers synced and pending threads (the synced case fails before the fix). On the POCO F4, with the app started offline, a synced settled thread offers no menu or swipe, an active thread offers only Settle and Snooze, and a pending settle offers only Un-settle, which cancels it without sending anything.

Packaged desktop app and a remote environment

Run at 2cc00a91fb. The DMG was built on shiv with vp run dist:desktop:dmg:arm64 (unsigned) and run from a task folder with its own T3CODE_HOME. Environment B was a second server on corex, paired to each client over plain HTTP behind a proxy that could cut the connection. A remote environment is the only place the offline disabled states show: a dropped connection keeps the loaded session, so every action stays enabled and a live-only one fails as "not connected", as on main.

Case	Packaged desktop, macOS 27.0.1	Web, Chromium on plain HTTP
Settle from the native menu while B is offline	Pending	Pending
Quit the app with it pending, relaunch while B is still offline	Still Settled and Pending (the queue survives in the app's IndexedDB)	n/a
Menus opened after starting offline	Synced settled thread: Un-settle, Pin, Rename, Archive and Delete disabled; Snooze, Mark unread, Copy and Project settings enabled	Same; an active thread offers Settle and Snooze, and a pending settle offers Un-settle
Un-settle on a pending settle	n/a	Cancels it, nothing sent
B back	Syncs, receipt accepted	Syncs, receipt accepted

Web, started with environment B offline: disabled menu items, a pending settle cancelled by Un-settle, and a queued settle that syncs when B is back.

web-remote-offline-start.mp4

Web, B dropped mid-session: the loaded session keeps actions enabled, and the queued settle syncs on reconnect.

web-remote-drop-mid-session.mp4

Packaged desktop: the settle is still Pending after quitting and relaunching while B is offline; the menu on a synced settled thread after starting offline; synced once B is back.

Pending after relaunch	Offline menu	Synced

After an outage of a few minutes, the reconnect took about 50 seconds on both clients; that's the existing reconnect backoff. After a short one it took 6 seconds. On a thread that already synced, the row's hover Un-settle and Wake buttons stay visible offline. Clicking one says "Failed to un-settle thread. corex is not connected."

The retest also found one bug: snoozing a thread whose settle was pending said " is not connected." d9d74d0173 makes it say to undo the pending settle first. The existing case in threadCommands.test.ts now checks the message; it fails before the fix and passes after.

Testing

• vp run check:changed origin/main at 5bc9fdaacd: format, lint, knip, typecheck of 7 packages, 22 test files and the React Compiler check passed.
• packages/client-runtime/src/state/threadCommands.test.ts: 49 tests pass, 25 of them for the offline queue. Each offline behavior was checked by removing its line of logic and seeing the matching test fail: the changed-thread check, the sent mark, the storage confirmation before a send, retry after a lost reply, Undo of an unsent change, Undo after a lost reply, the expired snooze, waiting for the synchronized shell, a reconnect while a change is being marked, a settle queued in another tab, a change another tab queued after this one loaded, and a later online action replacing a queued one.
• Web and mobile tests cover the one permission check (settle, snooze and their undo run before the session loads; other actions do not) and the Undo plan after a queued settle is cancelled.
• An independent review (gpt-6.1-sol in Codex) of the rewrite found four issues that are fixed in 0ab8f1810b, each with a test that fails without the fix: a send after a reconnect during the storage write, triage decisions made and undone elsewhere, a snooze replacing another tab's queued settle, and a failed session refresh hiding a loaded denial. One finding is listed under Limits instead: the cross-tab localStorage write window. Macroscope and CodeRabbit findings on the rewrite are answered on their threads; the ones that held are fixed, the last in 5bc9fdaacd.
• The web, Android, iOS and packaged macOS runs above.

Approvability

Verdict: Approved at 5bc9fda

Macroscope's review found this PR approvable — Offline settle and snooze actions now persist locally and sync when their environment reconnects, with pending indicators and undo support. Changed server state takes precedence, and server-side authorization remains enforced.

No code changes detected at 6c3c886. Prior analysis still applies.

Walkthrough

The change adds persistent queues for offline settle and snooze actions, replays applicable actions when environments reconnect, and updates triage authorization, undo behavior, and pending-sync indicators across web and mobile.

Changes: Offline thread triage

Full details: Out of Scope Changes check

Explanation

The reported changes support #24532. The shared outbox, platform storage, triage permission checks, pending-state UI, undo handling, documentation, and tests implement or verify offline settle and snooze. No unrelated change is established by the supplied summary.

Full details: Linked Issues check

Explanation

#24532 requires offline settle and snooze to queue locally, show as pending, replay on reconnect, and defer to the environment when the thread changed. The supplied change summary and test evidence support queueing, persistence, undo, replay, and conflict handling. Two documented conflict gaps remain: a snooze followed by a wake is not detected, and a change can occur after the client comparison but before the command is accepted. In either case, the queued action can apply after the environment changed the thread.

Resolution

Include wake transitions in the replay conflict state, and prevent a change between comparison and command acceptance from allowing the queued action to apply. Add automated tests for both cases.

Full details: Description check

Explanation

The description clearly explains the problem, implementation, limits, and verification. However, it does not provide the required maintainer approval for the broader behavior and scope change; it presents the policy choice as a call for review instead.

Resolution

Add a link to the triaged issue or approval discussion and identify the maintainer’s explicit approval of the direction and scope, including the approval comment. If this qualifies as a focused fix that needs no prior approval, explain why it is an obvious bug fix.

Pass triage = true in the snooze restore step of the settle Undo.

The doc comment on checkThreadOperationPermission says that settle, snooze, and their undo can queue offline. The snooze step in offerUndo calls the check without the triage flag. When the session is not loaded offline, readEnvironmentScope returns false. Undo of a settle on a snoozed thread then shows "This connection cannot change threads" instead of queueing.

The web runUndoPlan sends this step through snoozeThreadMutation, which uses readThreadTriageScope. Mobile and web behave differently as a result.

🐛 Proposed fix

-                  if (!checkThreadOperationPermission(thread, failureTitle)) return false;
+                  if (!checkThreadOperationPermission(thread, failureTitle, true)) return false;

apps/web/src/connection/threadTriageOutboxStore.ts: 1

28-31: Trivial · Stability & Availability · Quick win

Replace Effect.runPromiseExit inside the lock callback with a scoped lock acquisition.

Effect.runPromiseExit(effect) starts a new root fiber on the default runtime. This has two effects:

• Interrupting the caller does not cancel the queued lock request. The write runs later, after the caller has given up.
• The inner effect loses the caller's fiber context. Log annotations and spans do not reach the Effect.logWarning call in load.

This is persistence code, and docs/internals/effect-services.md limits Promise runners to application and framework boundaries.

Hold the Web Lock with Effect.acquireUseRelease, and pass an AbortSignal so interruption cancels a pending request. The effect then runs on the caller's fiber.

You must update the mock in threadTriageOutboxStore.test.ts (lines 26 and 60). It uses a request(name, callback) signature. The proposed code calls request(name, options, callback).

♻️ Proposed refactor

-      : Effect.tryPromise({
-          try: () => navigator.locks.request(STORAGE_KEY, () => Effect.runPromiseExit(effect)),
-          catch: (cause) => new ThreadTriageOutboxStorageError({ cause }),
-        }).pipe(Effect.flatten),
+      : Effect.acquireUseRelease(
+          Effect.tryPromise({
+            try: (signal) =>
+              new Promise<() => void>((resolve, reject) => {
+                navigator.locks
+                  .request(STORAGE_KEY, { signal }, () => new Promise<void>((release) => resolve(release)))
+                  .catch(reject);
+              }),
+            catch: (cause) => new ThreadTriageOutboxStorageError({ cause }),
+          }),
+          () => effect,
+          (release) => Effect.sync(release),
+        ),

As per path instructions: "Hold changed code to the rules in docs/internals/effect-services.md", which keeps runPromise and runPromiseExit out of persistence code.

[Opus 5.5][Claude Code] on behalf of shivam. Correction (2026-10-29): b61beeb3d4 never reached this branch. The same lock-cancellation fix landed as dfdc648 and ca72a3f, and 83d9f4d95f later replaced the Web Lock with IndexedDB.

[gpt-6.1-sol][Codex] on behalf of shivam.

The CodeRabbit Web Lock finding is addressed locally through b61beeb3d4ddb7231ba33b178d8dadc10a729eca, on top of the published caller-fiber fix c3cf935. Storage work stays on the caller's fiber. Lock requests receive an AbortSignal, and finalization aborts queued requests and releases granted locks. A callback that starts after cancellation also releases its lock immediately.

Failing first: queued cancellation on c3cf935 had no aborted signal. A grant-before-callback cancellation on 44e9a503c2 left the release promise pending until the project's default timeout. The final eight adapter cases pass, covering both cancellation points, caller logging, successful/failed writes, and unavailable/rejected locks. The three focused web files pass 30 tests.

Validation: full-PR Boat job j_ao2ihualh23si7ddj3ip on 44e9a503c2, default worker, attempt 1, exited 0 with format, lint, both Knip checks, GraphQL, 30 package typechecks, 458 tests and 1,164 React Compiler tests. Final-delta Boat job j_7b6kgqaa4pgwixg5fcd2 on b61beeb3d4, default worker, attempt 1, exited 0 with check:changed against 4994187: format, lint, both Knip checks, two package typechecks, eight tests, plus all 1,164 compiler tests. It verified final tree 7f579a3d6105a157e688435d4a6d74d82ba1036c and clean tracked source.

The two cancellation commits are not yet pushed. Their required independent review remains pending because T3 delegation returns Authentication required. Current-head browser and device behavior remain unverified.

[gpt-6.1-sol][Codex] on behalf of shivam.

The failed Test job on c3cf935f6a is an upstream mobile test-fixture failure, separate from the pending browser lock cancellation fixes. CI tested merge afd3b15f6545abe983b0d93a1d1242f049198864 against main c5332bf14dfb335c9eb08966624d65328e82641a. queries.debounce.test.tsx failed during import with ReferenceError: __DEV__ is not defined; the other 206 files and 2,425 executed tests passed. The Check job failed because Test failed.

I reproduced the same import failure in a detached checkout of that main commit on corex, using the existing installed dependencies: cd apps/mobile && vp test run src/state/queries.debounce.test.tsx, exit 1, no tests executed. A diagnostic mock of ./threads prevented the native runtime import and produced 4 passing tests, exit 0. The diagnostic checkout has been removed.

That exact fixture correction has since landed on main in #24954, commit 3ed489081ba023a4ef9293a0f2123120b841ee7d. The next branch update should include it; rerunning the old merge tree would retain the broken fixture. No feature source changed in this diagnosis.

Macroscope's updated approvability comment requests human review for scope and reports no new code finding. Local browser cancellation fixes remain at b61beeb3d4; their required fresh independent review is still blocked by T3's Authentication required response. Current-head browser/device runtime remains unverified.

150-154: Trivial · Maintainability & Code Quality · Quick win

Add a test for the failed-first-read retry in load.

The fix resets loading when the first read fails. The author says no test covers it. The repository testing rules require a failing test for a state bug fix. They also say to put it in an existing case where one fits.

makeHarness already exposes storage.failWrites, so a test needs little setup:

1. Seed one queued entry.
2. Fail the first read.
3. Clear the failure.
4. Trigger a re-read, for example by reconnecting so replayEntries runs.
5. Assert that pendingSyncAtom shows the entry.

The test must also show that a failed first read does not leave loading cached. Do not use sleeps or polling.

As per path instructions, **/*.test.*: "Hold changed tests to the rules in docs/internals/testing.md". As per coding guidelines, "Logic, data, state, and protocol bugs get a failing test first".

[Opus 5.5][Claude Code] on behalf of shivam.

@juliusmarminge could you go through this one? It was rewritten on 10 Nov and is much smaller and simpler than the version the earlier comments discuss.

What changed in the rewrite:

• It is client-only now. Nothing in apps/server or packages/contracts is touched, so there is no wire change and it works against servers of any version.
• One rule replaces the server guard, the cross-tab merging and the per-thread claims: when the environment's shell is synchronized again, each queued change is compared with the thread the server now reports. If the thread is as the user saw it, the change is sent under its stored command ID. If not, the server's state wins and the change is dropped.
• Storage is one small document, in localStorage on web and desktop and a file on mobile. The IndexedDB store and the Web Lock are gone.
• The diff went from +2,556 / −202 in 42 files to +1,503 / −140 in 34 files, and about 600 of the added lines are tests.

Comments above about the server guard, snapshotSequence, IndexedDB or Web Locks refer to code that is no longer in the PR.

Where to read: packages/client-runtime/src/state/threadTriageOutbox.ts holds the queue and the replay, threadCommands.ts hooks it into settle and snooze, and platform/threadTriageOutboxStore.ts is the storage. The web and mobile changes are the "Pending" marker and Undo.

Two things I'd like your call on:

• Before an environment's session has loaded (the app started while it was offline), settle, snooze and their undo are offered and can queue. The server checks the scope when the change is sent.
• The "did the thread change" check runs on the client right before the send, so a change landing on the server in those few milliseconds is not caught. The description lists this and the other limits.

Tested at the current head on web, Android, the iOS Simulator and the packaged macOS app, with recordings in the description. T3 Connect / relay connections are untested.
