What Changed

Threads that hit a subscription usage limit stay stopped after it resets until someone sends another message. I added an environment-wide Continue after usage limits setting, off by default, with an editable prompt that defaults to continue.

When the provider reports a recoverable subscription limit, the server waits for the reset and checks that the same account has usage available before sending the prompt in the existing thread. Pending continuations survive server restarts, and clients can be closed while the server is running.

Sending a message, stopping or archiving the thread, or disabling the setting cancels the pending continuation. Workspace credit and spending restrictions still require manual action.

Why

This lets unattended work continue when its subscription allowance becomes available again. Keeping it opt-in preserves existing behavior, while cancellation checks prevent a queued continuation from overriding later user activity.

I verified recovery, cancellation, account isolation, and restart behavior with focused tests using the real orchestration engine and SQLite. Scoped tests, typechecks, lint, and formatting passed. Native mobile interaction has not been verified.

Open Question

I made this an environment-wide setting. Would you prefer it to apply to all supported providers, or let users enable continuation and set the prompt separately for each provider?

UI Changes

The setting and prompt are under Settings > General on web and desktop, and Maintenance on mobile.

When someone of the maintainers approves going forward with this, I will add a screenshot of the added control. The UI changes are minimal, as this is mainly a backend/server feature.

Checklist

  • This PR is small and focused
  • I explained what changed and why
  • I included before/after screenshots for any UI changes
  • I included a video for animation/interaction changes

Summary by CodeRabbit

  • New Features

    • Added an optional Continue after usage limits setting to automatically resume threads when subscription allowance becomes available.
    • Added a customizable continuation prompt with validation, trimming, and input-length limits.
    • Added the setting to General settings and settings search on web and mobile.
    • Continuations persist across restarts and are canceled when thread or provider state changes.
  • Bug Fixes

    • Improved session-stop handling so cleared waiting errors are not restored incorrectly.
  • Documentation

    • Updated Codex usage-limit guidance and cancellation behavior.

Add opt-in continuation with a configurable prompt, persisted waits, and
usage checks. Cancel pending continuation on manual activity or disabled
settings, and clear waiting errors when threads are archived.

Cover recovery and cancellation with real orchestration and SQLite tests.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a substantial production workflow that persists usage-limit waits, probes provider limits, and can automatically start future turns, alongside new settings and product defaults. Its cross-cutting runtime impact and unresolved race/cancellation risks require human review.

Not approved because:

  • 2 blocking correctness issues found at or above your repo's Minimum Blocking Severity

Adjust the Minimum Blocking Severity for this repo — including turning it Off — in Settings. You can add or adjust custom eligibility rules. Learn more.

Scan the full captured event range when checking for cancellation. Allow
a failed continuation write to be retried when its failure is redelivered.

Cover cancellations beyond the default replay limit and a failed SQLite
write with focused regression tests.

📝 Walkthrough

Walkthrough

Changes

The pull request adds optional usage-limit continuation. It introduces validated settings and prompts, provider recovery hints, durable pending state, guarded orchestration commands, automatic retry processing, and web/mobile settings. It also updates related session and archived-thread behavior.

Usage-limit continuation

Layer / File(s) Summary
Contracts and provider signals
packages/contracts/..., apps/server/src/provider/Layers/...
Contracts define continuation settings and guarded commands. Codex events now include eligible usage-limit recovery hints.
Persistence and orchestration
apps/server/src/provider/..., apps/server/src/persistence/..., apps/server/src/orchestration/...
The server persists pending continuations, waits for refreshed limits, dispatches guarded continuation turns, and restores or clears errors as state changes.
Session and projection consistency
apps/server/src/orchestration/Layers/ProviderCommandReactor.*, apps/server/src/orchestration/Layers/ProjectionSnapshotQuery.*
Session-stop updates use current-session guards. Thread lookup can include archived threads while excluding deleted threads.
Settings, wiring, and documentation
apps/web/src/components/settings/..., apps/mobile/src/features/settings/..., apps/server/src/server.ts, docs/user/providers-codex.md, apps/server/**
Web and mobile settings expose the feature and prompt validation. Runtime layers and test doubles provide the new dependencies.

Recognize the waiting banner independently of its displayed retry time.
Keep the failed-turn and session guards so cancellation restores the
original error even if a rescheduled banner could not be written.
