The headline: the quietest window in weeks — zero commits, zero issues opened or closed — while PR #3536 stays frozen at the same commit for a second straight day

Window: 2026-08-28T23:00Z → 2026-08-29T23:00Z. No commits landed in this repo in the window (the only commit git log surfaces is yesterday's own daily-review post, 5e104b8d, which lands right at the window boundary). No GitHub issues were opened or closed. The dedicated agent-debugger job also ran today (internal:162087, 21:08 UTC) and independently found no new high-confidence root-cause bugs to file. Task throughput stayed strong and clean — 40 claude/sonnet successes plus ~23 opencode free-tier successes, only a single routine rate_limit outcome, and only one error-type activity event logged all day (well below recent days). The one open thread is unchanged: 156854/#3535/PR #3536 has been stuck at the same head commit for over 48 hours now.

What Shipped (Last 24h)

Nothing. No commits merged to main in the window. This is expected some days — no code changes doesn't mean no activity; see Operational Health below for the day's actual work (task throughput, debugger job, PR #3536 investigation).

Operational Health

Task Run Outcomes (last 24h)

The single rate_limit outcome went through the existing generic cooldown/failover path — no new failure shape, no operator action needed. task_activity for the window: status_change 196, dispatch 66, push 64, branch_delete 56, review_start 31, pr_create 31, routed 30, review_decision 30, error 1 — the lowest error count in recent memory, and a healthy dispatch-to-push-to-review pipeline throughout.

orch.error.log

0 bytes — no crash since last restart.

Routing and cooldowns

orch cooldown list shows four persisted, standard exponential-backoff cooldowns (codex:gpt-5.4, kimi:opus, minimax:haiku, minimax:opus), all consistent with normal rate-limit/credit-exhaustion recovery. No repeated-cooldown or silent-model-failure patterns. One transient opencode models command failed (exit_status_failure) fired mid-afternoon and correctly fell back to the cached model list — the stderr-capture fix from #3564 is exactly the kind of visibility this needed, so if this recurs the next log should show why.

Backlog and stuck work — the PR #3536 saga, day 3 of the same head commit

156854/#3535/PR #3536 remains the only task blocked in this repo (now 9 days), and PR #3536's headRefOid and updatedAt are still 2026-08-27T23:08:04Z — unchanged since the manual diagnostic unstick two reviews ago. mergeStateStatus is BEHIND.

The warn!-level logging added by #3563 (merged 2026-08-28) to surface update_pr_branch/enable_auto_merge failures has not appeared even once in the retained service log, which now spans the full window back to 2026-08-26T12:09Z — comfortably longer than one sweep cycle. Today's agent-debugger job looked at this same question and filed nothing, consistent with the SKILL.md guidance to stop at "the fix is in the repo" rather than speculate about whether a given code path is live in the currently running process. Per repo policy this review does the same: the fix exists in the repo; future sweep cycles should be evaluated against it. No new issue filed on this — there's no new evidence since the last review, only continued absence of the expected log line.

Policy alignment

Current operational behavior matches prompts/skills/orch/SKILL.md — no drift detected.

Issues Filed Today

None. Zero commits and zero issue activity in the window; the dedicated agent-debugger job (internal:162087) also reviewed the last 12–72h independently and found nothing meeting the bar to file. Re-filing on the still-unconfirmed #3536 sweep hypothesis without new evidence would just be noise.

Priorities for Tomorrow

1. Watch for the first update_pr_branch/enable_auto_merge warn! log line. It has now gone unobserved across a full window of retained logs — if it still hasn't appeared by tomorrow's review, that silence itself (not a version check) is the signal worth escalating on.
2. Watch whether 156854/PR #3536 finally recovers — it's now 9 days blocked at an unchanged head commit for over 48 hours.
3. No other action items — today was unusually quiet on the commit/issue front but operationally clean: high task throughput, minimal errors, no new failure patterns.
