Warning

Review limit reached

@alm0ra, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 51 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

Changes

The application now sends eligible plain-text follow-ups to active Codex turns through turn/steer. It queues messages with attachments or failed steering attempts as new turns. Codex validates responses and cleans up pending steering requests.

Active-turn steering

Layer / File(s)	Summary
Codex steering runtime src/codex.rs	Adds steering request types, queues requests before turn activation, sends turn/steer requests during active turns, validates responses, and rejects pending requests when execution ends.
Application turn integration src/app.rs, src/app/turns.rs	Tracks active steering handles, routes eligible messages to active turns, audits successful steering, and falls back to session queuing after failure or timeout.
Steering validation and documentation src/app/tests.rs, src/codex.rs, README.md, src/app/turns.rs	Adds steering tests, preserves existing context-pressure behavior, and documents steering with queue fallback.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 9e500

This change routes plain-text Telegram follow-ups into an active turn, but a steering request that times out can still be accepted later while the same message is queued, causing duplicate processing. The timeout path should be corrected before merge, and the documented fallback behavior should be completed.

Poem

A rabbit nudges text through the turn,
While queued requests wait their return.
Attachments stay in line,
Responses match by design,
And Codex hops where messages burn.

- Around line 1696-1699: Update the active turn steering timeout handling around
the response_rx await so it does not return Ok(false) or queue the message as a
new turn while the turn/steer request may still be pending in Codex. Retain the
message as pending on timeout, or wait for an end-to-end cancellation/terminal
rejection acknowledgement before allowing the fallback enqueue path; preserve
queueing only after confirmed rejection.

[alm0ra]

Addressed the review findings in commit d56404c:

• Removed the five-second timeout fallback that could enqueue a message after turn/steer had already been delivered.
• Steering now remains pending until Codex accepts it, terminally rejects it, or closes the response channel; only the latter two cases fall back to the session queue.
• Updated the README to document unavailable/terminally rejected fallback conditions.
• Added a virtual-time regression test that advances past the previous timeout and verifies the request is not queued prematurely.
• Added documentation for the new steering types and helpers.

Validation: cargo fmt --check, strict cargo clippy, and all 138 tests pass.
