Failed turns hide why they stopped behind disclosures. Keep the turn and its preceding activity visible, with the failure and timestamp directly in the transcript.

Place the assistant actions below the failure to remove the extra gap. Usage limits read “Usage limit reached. Retry after ” using the persisted reset time, with no redundant description. Other failures retain their full message. Web and desktop share the renderer; mobile retains long-press copy and stable history rows during streaming. Successful turns keep their existing folding behavior.

Verification: 224 focused timeline and timestamp tests pass, scoped web/mobile typechecks pass, and targeted lint passes with existing warnings. Live browser verification covers reload, retained failure after continuation, copy, and narrow layout. Mobile was verified with automated tests and typecheck.

Before, on provider-limits/snooze:

Before: failed turn details require expansion

After:

After: compact inline limit and reset time

Recording: reload the continued thread with the failure visible

Model: GPT-6. Harness: Codex.

Summary by CodeRabbit

Bug Fixes
- Failed provider and usage-limit activities remain visible as individual entries instead of being folded into completed work.
- Failed entries use prominent warning or error styling, with usage-limit warnings showing localized retry times when available.
- Usage-limit warnings no longer display the failure message; other failure messages remain available and selectable.
- Timestamps remain visible and readable, including retry information and past dates.
- Completed activity remains visible while a related run is still in progress.

Approvability

Verdict: Approved at b7b6d19

Macroscope's review found this PR approvable — This is a focused, tested fix that keeps failed turns and their preceding activity visible across web and mobile without changing successful-turn behavior. An unresolved Medium finding remains that web usage-limit rows omit provider-specific failure details.

Notes:

This verdict was updated automatically after the outstanding correctness findings were resolved. Macroscope did not re-review the code.

No code changes detected at 13e48c4. Prior analysis still applies.

📝 Walkthrough

Walkthrough

Failed runs and top-level failed errors now remain visible as separate, non-expandable activities in mobile and web timelines. Usage-limit rows show localized retry times when available. Other failed rows retain their messages and timestamps.

Changes

Failed activity visibility

Layer / File(s)	Summary
Failure detection and unfolding `apps/mobile/src/lib/threadActivity.ts`, `apps/web/src/components/chat/MessagesTimeline.logic.ts`	Failed runs and failed error activities are excluded from normal grouping, run folding, and superseded-attempt folding. Failed groups are split into individual rows.
Failure row rendering `apps/mobile/src/features/threads/thread-work-log.tsx`, `apps/web/src/components/chat/ThreadFeed.tsx`, `apps/web/src/components/chat/MessagesTimeline.tsx`, `apps/web/src/components/chat/WorkLog.tsx`, `apps/web/src/timestampFormat.ts`	Failed errors render with severity styling, visible timestamps, and preserved messages. Usage-limit rows show localized retry text and omit the failure message.
Failure regression coverage `apps/mobile/src/lib/threadActivity.test.ts`, `apps/web/src/components/chat/MessagesTimeline.logic.test.ts`, `apps/web/src/timestampFormat.test.ts`	Tests cover failed provider and usage-limit turns, preserved command activity, separate presentation, timestamps, and assistant metadata.

Usage-limit failures lose their provider-specific explanation in both clients, so users cannot see the complete reason a turn stopped. Restore the message before merging.

Preserve the failure-row copy action.

This early return bypasses the standard WorkLogPressable and its onLongPress handler. A long press on a failed provider row no longer calls props.onCopyRow(row.id, row.getCopyText()) or shows the copied state. Wrap the failure row with the existing pressable behavior.

JJulius MarmingeSep 20, 2026

This is intentional per the maintainer’s request: remove the redundant description and show “Usage limit reached. Retry after ” using the persisted reset time. A usage_limit item already identifies why the turn stopped; “Plan limit reached” repeats that state. The provider message remains persisted, and other failure classes still render their full message. Restoring this paragraph would undo the requested UX change.

Intentional UX requested by the maintainer: remove the description paragraph and show a brief usage-limit state plus the persisted reset time. Both clients now say “Usage limit reached. Retry after ”. The native message is still persisted and copyable on mobile; other failure classes still show their full message. Restoring the paragraph would reverse the requested change.

CcoderabbitaiBotSep 20, 2026

@juliusmarminge, thanks for the clarification. The current behavior matches the requested UX: usage-limit rows show the concise state and persisted reset time, while the native message remains copyable on mobile. Other failure classes retain their visible full message.

I withdraw this finding.

5	Learning: For usage-limit failures in the web and mobile transcript renderers, the requested UX intentionally omits the provider-specific failure-message paragraph. The row must show “Usage limit reached. Retry after <time>” when a persisted reset time is available. On mobile, the native failure message remains available through long-press copy. Other failure classes must continue to display their full failure message.
