Evening Retrospective — 2026-04-29

Throughput stayed healthy today and one production reliability fix shipped (#3027 / commit e0a2fa34) to stop auto-merge stalls when workflows are skipped by paths-ignore. Failures were concentrated in known edges rather than broad instability.

What Was Accomplished

Issues closed today

IssueOutcomeWhy it mattered
#3030ClosedFixed final-status normalization path where agent outputs could map to unknown instead of done.
#3029ClosedHardened transient GitHub API error classification for circuit-breaker strings.
#3027ClosedFixed auto-merge pending loop when CI workflows are filtered out (total=0 with workflows present).

Commits in the last 12 hours

  • e0a2fa34 fix(auto_merge): trust mergeable_state=clean when no check runs match paths-ignore PRs

Execution Quality (task_runs, last 24h)

Outcome totals:

  • success: 88
  • failed: 4
  • rate_limit: 1
  • blocked: 1
  • push_failed: 1
  • aborted: 1
  • NULL outcome (in-flight/accounting): 3

Approximate success rate excluding NULL rows: ~92.6% (88/95).

Failure and retry patterns

  1. Retry hotspot on #3031

    • #3031 ran 12 times in the last 24h (11 successes + 1 failure) and remains open/in_review.
    • Latest non-success record: max attempts reached.
    • This is now the primary churn source and should be stabilized first tomorrow.
  2. Model-availability miss still appears in fallback paths

    • One failure still attempted opencode/github-copilot/gpt-5.3 (Model not found).
    • Router alias hardening exists, but runtime fallbacks can still surface dead IDs in some branches.
  3. Rate limits are isolated

    • Single claude:sonnet rate-limit event with no cascade.
  4. One blocked + one push_failed are task-specific

    • Blocked run tied to a worktree lock/permission condition on an internal task.
    • push_failed appeared once under minimax:opus; no repeat pattern in this window.

Routing Accuracy

Routing remained mostly accurate:

  • High-volume lanes (codex:gpt-5.3-codex, claude:sonnet, minimax:opus, kimi:opus, glm:opus) produced most successes.
  • Review pipeline throughput remained strong (review/success: 34).
  • Misses were concentrated in known fallback/model-availability edges, not general misrouting.

Morning Plan vs. Actual

From this morning’s priorities:

  • Unblock/resolve #2789: not completed (still open/blocked).
  • Clear internal:148540: not closed in this snapshot.
  • Reduce review-loop churn: partially completed via #3027 fix to pending-with-zero-checks behavior.
  • Reconfirm dead-model hygiene: improved but not fully eliminated (one dead model hit still observed).

Open / Pending

  • #3031 (open): in-review churn with repeated attempts; now the highest-priority reliability follow-up.
  • #2789 (open): long-lived blocked artifact-collection task.

No additional new root-cause bug was identified that is not already represented by open or just-closed issues.

Prompt/Workflow Observations

  • Prompt/response format quality is stable; parser regressions were not the dominant source of failures today.
  • The majority of non-success outcomes came from operational edges (attempt exhaustion, dead model fallback, single push/worktree incidents).
  • Current prompts are generally effective; reliability gains are now mostly in routing/fallback and retry policy behavior.

Priorities for Tomorrow Morning Review

  1. Stabilize #3031: inspect why it reached max attempts despite high per-run success and tighten reroute/review transition criteria.
  2. Close or re-scope #2789 with explicit artifact-capture acceptance criteria and owner handoff.
  3. Verify dead github-copilot/* model IDs cannot re-enter runtime via fallback/model pool paths.
  4. Validate that #3027 eliminated repeated pending-with-zero-check checks in fresh review_poll logs.
