Fixes the supervisor flip-flop tracked as agentflare item #691 (not a GitHub PR number).

Problem

On PR #829 the supervisor posted ~358 "CI green" and ~359 "CodeRabbit review repair cap reached" comments, one pair per sweep. coderabbit_repair_or_gate capped and set needs-human; handle_ci_green then saw a green PR carrying needs-human, reverted it to in-review and commented; the next sweep capped again.

Changes

  • handle_ci_green (merge.rs): leaves needs-human alone while CodeRabbit repair is capped with unresolved findings. The capped lookup only runs when the PR carries needs-human.
  • coderabbit_repair_or_gate (review_bots.rs): the cap is announced once per findings fingerprint (metadata key coderabbit_repair_cap_for, with the cap comment as a fallback, matched exactly). The item needs-human-gate label is always applied.
  • A recorded cap is cleared when the findings clear, so needs-human can be reverted on a PR that is clean again.
  • If the cap was announced but the PR does not carry needs-human (the label swap failed), the label is re-ensured on later sweeps without a new comment.
  • Body-level findings: a fixed result reported under a non-thread id is dropped once its sha is on the PR; reply_and_settle posts the reply and logs, rather than fails, when the thread cannot be resolved.
  • reply_then_resolve had no production caller left and is removed with its tests.
  • supervisor.rs: test-only, thread-local recording of PR-stage comments.

Tests

  • coderabbit_cap_and_ci_green_do_not_flip_flop_across_sweeps: 8 sweeps of handle_ci_green + coderabbit_repair_or_gate, with the cap branch re-entered each sweep; zero "CI green" PR comments and exactly one cap comment.
  • coderabbit_cap_announced_requires_exact_fingerprint_not_substring, plus the cap-closes assertion on the fingerprint-differs test.
  • sweep_drops_a_body_level_fixed_result_once_its_sha_is_on_the_pr, sweep_settles_a_fixed_thread_when_resolve_fails_like_body_level_findings.

Known and left as is

  • When the PR already carries needs-human, a cap on a new fingerprint adds the item gate label without a new comment or notification. This is the intended anti-spam behaviour, but it means a second cap on an already-gated PR is silent.
  • The cap comment embeds the raw findings fingerprint (can be long). A short hash would read better.
  • src/mcp_server/types.rs (the thread_id description for review_result) still says a fixed result under a non-thread id is reported in a PR-level comment; it is now dropped once its sha is on the PR.

Summary by CodeRabbit

  • Bug Fixes
    • Review findings now remain pending until the commit containing the fix appears on the pull request. A thread-resolution failure no longer prevents a posted fix reply from being retained.
    • When repair limits are reached and findings remain unresolved, the needs-human gate stays active, and repeated checks avoid reposting the same limit notice.
    • After findings are cleared, passing CI can remove a stale repair-stage label and post a CI-green comment.

📝 Walkthrough

Walkthrough

The change updates CodeRabbit repair-cap tracking, human-gate labels, and CI-green stage handling. Fixed review results remain pending until their reported SHA appears on the PR. Thread replies now precede best-effort resolution.

Changes

Repair lifecycle

Layer / File(s) Summary
Repair-cap tracking and announcements
src/supervisor/review_bots.rs, src/supervisor.rs, src/supervisor_self_repair_tests.rs
Repair attempts and findings fingerprints control cap detection, announcements, and cap clearing. Tests cover repeated sweeps and fingerprint changes.
CI-green stage and merge handling
src/supervisor/merge.rs
CI-green handling preserves the needs-human label when a repair cap remains unresolved. After findings clear, the merge flow clears the cap before approval-gated merging.
Fixed finding completion
src/supervisor/review_bots.rs, src/github/review_threads.rs, src/supervisor/tests/review_bots_tests.rs
Fixed results remain pending until their reported SHA appears on the PR. Thread replies precede best-effort resolution. Detached fixed results are excluded from PR-level comments.

A capped PR can remain in the human-gated state after its findings are resolved, requiring intervention before automated progress resumes. Resolve this cleanup gap before merging.

- Around line 83-85: Replace the process-wide PR_STAGE_COMMENTS_FOR_TEST mutex
with a test-local recorder, such as thread-local storage, and update its
synchronous recording and draining call sites to use it so concurrent tests
cannot interfere.

Review comments at @src/supervisor/merge.rs:
- Around line 24-27: Update the stage-selection logic using
SELF_REPAIR_PR_LABEL, NEEDS_HUMAN_PR_LABEL, and coderabbit_capped so it returns
no stale stage whenever the PR is capped and has the needs-human label, even if
self-repair is also present. Preserve the existing selection behavior in other
cases.

Review comments at @src/supervisor/review_bots.rs:
- Around line 122-125: Update the completion predicate used by
coderabbit_repair_or_gate to compare completion against the fingerprint of the
current capped findings, rather than only the previously announced fingerprint.
Ensure new findings at the attempt cap are still recognized as requiring repair
or gating, and that handle_ci_green does not remove their needs-human label on
later sweeps.
- Around line 145-148: Update the capped-comment matching in the comments
iterator to extract the stored fingerprint field and compare it exactly with
fingerprint; do not use substring matching, so only an identical capped set is
treated as already announced.
- Around line 401-407: Pending fixed results can be removed from metadata after
detached-result posting even when their fix SHA is not on the PR. Update
post_detached_results to exclude pending fixed results from both posting and
removal, preserving them until the SHA is confirmed; keep the existing
update_metadata and remove_thread_result behavior for eligible results.

…man label swap

Review follow-ups on the cap / CI-green flip-flop fix: drop a detached fixed result once its sha is on the PR (the previous branch was unreachable), clear the recorded cap when findings clear so needs-human can be reverted, re-ensure the needs-human PR label when the cap was announced but the label swap failed, make the regression loop re-enter the cap branch, skip the capped lookup unless the PR carries needs-human, and remove the unused reply_then_resolve.

- Line 503: Update handle_ci_green to perform a targeted clean-review check for

call clear_coderabbit_repair_cap when that check confirms the findings are
clear. Preserve the existing gate behavior for items without a recorded cap.

- Line 121: In the repair-cap handling flow, check `current_metadata(mcp,
item).contains_key(CODERABBIT_REPAIR_CAP_KEY)` before the attempt-count guard so
a recorded cap is honored even when `coderabbit_repair_prior_attempts` returns
fewer attempts. Preserve the existing capped behavior, including preventing the
`needs-human` label removal and CI-green comment path.
