GitHub fork: fix/mobile-resume-usage-limit

View on GitHubTwo-way sync enabledPR last imported 9d ago

Fixes #27187. Replaces #27190, which was closed for missing mobile evidence; this PR is the same branch, merged with current main, plus that evidence.

On mobile, tapping Resume queue on a thread whose last run stopped on a usage limit did nothing. Mobile only sent queue.resume. The server rejects that while a limit holds the queue ("Continue the limited thread before resuming its queue."), and the error was only logged.

This hits hardest when the limit has no reset time. I run Claude through CLIProxyAPI, which answers a limit with a plain 429, so T3 Code stored the failure with resetAt: null. Without a reset time the automatic resume never schedules, and a manual continue is the only way out, which mobile lacked.

Fix

Moved the web's inline "which run can be continued" logic into deriveResumableRunId in client-runtime, so web and mobile share one rule: the latest run was interrupted, or it failed on a usage limit.
Mobile's Resume now sends the manual continuation (startTurn with manualContinuationOfRunId, "Continue where you left off.") before resuming the queue, the same as web's useComposerResume.
Before continuing, mobile saves a runtime or interaction mode changed in the composer to the thread, as web and mobile's normal send do. The server reads those modes from the thread, not the turn.
Mobile now shows a failed continue or resume once, in a dialog, instead of only logging it.
Mobile offers Resume whenever the latest run can be continued, not only when the queue is held, and resumes the queue only when runs are held, matching web. The button is labelled "Resume thread" like web, and the composer guide no longer names a separate mobile label.

Not covered

The queue sheet's per-message "send now" (queued-run.start) hits the same server check on both web and mobile. Left for a separate change.

Evidence

iOS Simulator (iPhone 17 Pro, iOS 26.5), T3 Code Dev client, isolated dev server. The usage limit is real provider behavior: the Claude provider (Claude Code, claude-haiku-4-5) ran against a local stub of the Anthropic API that answers 429 rate_limit_error with no reset header, the same response CLIProxyAPI gives. The Claude adapter classified it as usage_limit with resetAt: null, and the app shows "The provider did not report a reset time." Switching the stub to a normal streamed reply stands in for the limit lifting. "Before" is this branch with main's three mobile files checked out under the same Metro and server; "after" is this branch.

Limited thread with a queued follow-up

Before (`main`)	After (this PR)

Before: tapping Resume does nothing; Metro only logs [atom-command] resume queue failed. After: Resume continues the limited run, then the held follow-up runs.

Limited thread with nothing queued

Before (`main`)	After (this PR)

No recording: there is no Resume button to tap.

Before: no Resume, only a disabled send button, though the banner says to retry manually. After: Resume is offered and continues the run.

Error state

After: dialog	After: recording

With the backend stopped, Resume shows "Could not resume thread" once, with the reason. On main the same failure is only logged, as in the queued "before" recording.

More stills: queued, before tap, nothing queued, after tap.

Verification

Extended the existing threadExecution.test.ts cases: a limited run with and without a queue, and an interrupted run with a held queue. They fail without the helper and pass with it. A provider-error run is not resumable.
vp run check:changed after merging main: format, lint, knip, typecheck (7 packages), tests (3 files, including ChatView.logic.browser.test.ts) and the React compiler check pass.
Tested in the iOS Simulator as above. Not tested on Android or a physical device.

Walkthrough

The change centralizes resumable-run selection for web and mobile. Mobile now continues a resumable run before resuming a held queue, and shows the Resume control when a run can be continued. Composer labels and documentation describe the updated Resume behavior.

Changes: Thread resume

Layer / File(s)	Summary
Shared resumable-run selection `packages/client-runtime/src/state/threadExecution.ts`, `packages/client-runtime/src/state/threadExecution.test.ts`, `apps/mobile/src/state/use-thread-composer-state.ts`, `apps/web/src/components/ChatView.tsx`	`deriveResumableRunId` selects an interrupted run or a failed run whose runtime and provider failure classes are both `usage_limit`. Mobile and web use the helper. Tests cover these selection cases.
Mobile continuation and queue resume `apps/mobile/src/features/threads/resume-thread.ts`, `apps/mobile/src/features/threads/resume-thread.test.ts`, `apps/mobile/src/features/threads/ThreadRouteScreen.tsx`, `apps/mobile/src/features/threads/ThreadComposer.tsx`, `docs/user/composer.md`, `docs/user/thread-sidebar.md`	Mobile saves changed modes and continues a resumable run before resuming a held queue. The Resume control appears for a held queue or a resumable run. The composer accessibility labels and user documentation use the updated Resume wording and behavior.

Full details: Description check

Explanation

The description explains the problem, implementation, scope limitation, verification results, UI evidence, and untested platforms. It uses “## Fix” instead of the template’s “## Change” heading and does not provide a separate “## Scope and approval” section, but the linked issue and focused scope provide the required context.

Full details: Linked Issues check

Explanation

Issue #27187 is active and has coding requirements. deriveResumableRunId selects the latest interrupted run or a latest usage_limit failure. Mobile exposes Resume when that helper returns a run or when the queue is held. resumeThread saves changed thread modes, sends startTurn with manualContinuationOfRunId, and resumes a held queue after successful continuation. Mobile reports command failures in a dialog. Tests cover limited runs with and without queued work, interrupted runs, non-resumable provider errors, mode saves, and queue resumption.

Full details: Out of Scope Changes check

Explanation

The runtime helper, mobile resume flow, web delegation, labels, documentation, and tests support issue #27187. The queue-sheet per-message queued-run.start flow remains explicitly excluded and is not required by the linked issue.

Add the required mobile Resume regression test.

AGENTS.md:105,111 requires behavior tests for logic changed by a bug fix and a failing test first for logic and state bugs. The existing shared-selector test does not exercise ThreadRouteScreen.tsx:711-778, so this PR lacks the required proof for the changed mobile action.

Add a focused action test that renders a resumable run with a held queue and triggers Resume. Assert that continueThreadRun receives manualContinuationOfRunId and completes before resumeThreadQueue runs. Add a continuation-failure case and assert that resumeThreadQueue is not called. Test the action behavior, not static props or callback wiring.

🤖 Claude Opus 5.5 responding on behalf of AbdelrahmanTamer21

Fixed in b0d0762e85. The Resume sequencing moved out of ThreadRouteScreen into resumeThread (apps/mobile/src/features/threads/resume-thread.ts), and resume-thread.test.ts now drives it with recorded commands:

With a resumable run and a held queue, startTurn gets manualContinuationOfRunId and settles before resumeQueue runs.
When the continuation fails, resumeQueue is not called and the failure is returned for the dialog.
With nothing queued, only the run is continued.
Changed modes are saved before the continuation.
With no resumable run, the queue resumes directly.

Checked against main's behaviour (queue resume only): 4 of the 5 cases fail. The direct-resume case passes on both, as it should. vp run check:changed passes.

@AbdelrahmanTamer21 The extracted resumeThread tests address this finding. I inspected the helper and all five cases. They cover continuation before queue resume, failure propagation without queue resume, continuation without queued work, mode saves, and direct queue resume.

AGENTS.md requires tests at the lowest layer that exposes the bug. A duplicate ThreadRouteScreen render test is not needed here.

I verified the code and assertions by inspection. I did not rerun tests or vp run check:changed.

Verified in a real dev environment

partial verification of head b0d0762e85a1d7a299581f881bde80a7d19819ab on a disposable linux vm. no source changes or pushes.

ran vp i and background vp run dev on github/main (5fe18d79ac835e0f193ad61325e5b7d69a317bcf) in a separate worktree, stopped that server, then ran the exact pr head with isolated state. used repository playwright and /usr/bin/google-chrome.
created a project through the app pointing to a real git repository. used real codex gpt-6.1-sol turns through the local proxy, without mocks, seeded data, replay, or provider stubs.
on both main and the pr, started a command, queued a follow-up, stopped the turn, and clicked web's resume. the continuation completed before the queued follow-up. the pr recording shows the held message, resume, both real replies, and the final idle composer. this exercises the shared resumable-run rule changed by this pr.
separately stopped a turn with nothing queued. web offered resume. invoked the pr's actual mobile resumeThread helper against the running server's authenticated websocket protocol with clientSurface=mobile. it saved a changed permission mode, dispatched the manual continuation, skipped queue resume, and the real provider replied mobile continuation finished. this checks the mobile action's server/provider integration, not native ui wiring.
blacksmith-check ran vp i and the existing resume-thread.test.ts and threadExecution.test.ts: 23 tests passed. the reported head ci has 28 successful checks.

Not verified

the original mobile usage-limit bug was not reproduced on main. native device access reports Agent device access is turned off for this environment. no android device is connected. neither native ios nor android resume controls, voice presentation, nor the failure dialog was exercised.
no genuine provider usage limit occurred, so recovery from usage_limit, especially resetAt: null, remains unverified. an interrupted run proves continuation and queue ordering, but does not prove that limit-specific path. no synthetic limit was injected.
native mobile continuation with a held queue and interaction-mode changes were covered only by the existing tests, not a native client.
the first pr thread needed one browser reload before its live turn controls appeared. subsequent stop/resume turns updated live. this was not isolated to the pr diff.
desktop, other providers, remote/relay connections, and the excluded per-message send-now path were not exercised.

the recording was trimmed, inspected, uploaded, and checked for playback and seeking in t3's browser. reopening this comment showed that git.cafe renders the external media embeds as links; opening the uploaded media works. this is partial runtime evidence, not a full sign-off on the reported native usage-limit fix.
