The headline: three narrow classifier/lifecycle fixes shipped, and the review agent itself just supplied live evidence for two of the three new bugs it filed

This was a normal fix-and-verify day. Three real fixes landed (all root-cause, all previously diagnosed in earlier reviews). Three new issues were filed, and — unusually — the service log from this very session independently corroborated two of them while they were still open: the router LLM pool cooldown and a kimi review-agent billing 403 both showed up live in orch log 200, matching the exact failure modes described in #3481 and #3478.

What Shipped (Last 24h)

3 commits landed, all fixes:

All three were flagged in the prior two daily reviews and are now closed. No functional regressions expected — each is a narrow, well-scoped parser/classifier/test-hygiene fix with the root cause identified down to the exact line before the fix landed.

Operational Health

Throughput and Activity

task_activity in the last 24 hours:

Volume is up across the board versus yesterday's quiet window (status_change 155→215, dispatch 58→79) — a normal, busier throughput day. 27 tasks reached done.

Task Run Outcomes

task_runs outcomes in the last 24 hours:

Non-Success Breakdown

• rate_limit (kimi opus, ×3) — billing-cycle 403s ("You've reached your usage limit for this billing cycle"), one of which is the live example filed in #3478 (task 3478's own review run failed this way at 23:15 UTC during this session). Correctly classified and cooled; the underlying bug is that a successful review run on a review-only model never resets its failure count, so intermittent billing 403s ratchet the model into progressively longer cooldowns instead of resetting on the next success. Already filed, PR #3483 open with CI running.
• codex gpt-5.4 (failed, ×1) — model unavailable (gpt-5.4): Model metadata for 'gpt-5.4' not found. Same known-cooled model as prior days (codex:gpt-5.4 now 4d4h remaining). Working as designed.
• opencode/ling-3.0-* (parse_error / failed, ×4 combined) — same failure family as the just-shipped #3473 fix; expect this count to drop in tomorrow's window now that step_finish reason="length" is classified correctly.
• claude sonnet (failed, ×1) — silence detection reset to new, self-recovered, existing generic mechanism.
• minimax opus (rate_limit, ×1) — recurring billing-cycle exhaustion; cooldown now 5d21h remaining, consistent with the settled exponential escalation.

Live Evidence for the Router LLM Pool Bug (#3481)

This session's own routing hit the exact failure mode described in #3481: orch log 200 showed all router LLM pool entries on cooldown — will try fallback for tasks 3478/3479, and orch cooldown list confirms all three router pool entries are now on 1d10h–1d23h cooldowns:

claude:haiku    1d22h
kimi:haiku      1d23h
minimax:haiku   1d10h

This is the router's cheap classification pool, not the task-execution models — when all three are cooled, routing falls back to weighted round-robin. Root cause (already diagnosed in #3481): route_with_llm() calls record_model_failure() on every timeout but never calls record_agent_success() on a successful pool call, so intermittent hiccups ratchet indefinitely instead of resetting. Fix is scoped to two call sites in src/engine/router/mod.rs; task 3481 is actively working it (3 attempts so far — see below).

Logs and Cooldowns

• /opt/homebrew/var/log/orch.error.log is 0B — no fresh errors.

• Active cooldowns (orch cooldown list):

  Key	Remaining
  codex:gpt-5.4	4d4h
  claude:haiku	1d22h
  kimi:haiku	1d23h
  kimi:opus	1d11h
  minimax:haiku	1d10h
  minimax:opus	5d21h
  opencode	34m

  All persisted, all decaying/escalating per the generic cooldown system. The four *:haiku/kimi:opus entries reflect exactly the router-pool and review-model reset gaps described in #3481/#3478.

Backlog and Stuck Work

• Blocked task count holds steady — same shape as prior days: the majority in one downstream repo still CI failure limit reached during auto-merge with PRs still open, a handful on GitHub Actions billing failure at merge time, one review agent rebroadcast escalated, one max review cycles exceeded. All correctly-designed per-task block-at-merge-time behavior, no new pattern.
• internal:155976 (Daily evening retrospective, another repo in the queue) — routed, 21m age at observation time, not yet dispatched. Not this repo's task, no action here.
• Orch's own repo queue: this review task plus three actively-worked bug tasks (#3481, #3482, #3479) and one in_review (#3478, PR #3483 with CI running). Nothing stuck or aging abnormally — the oldest of the four (#3481) has 3 attempts, consistent with it hitting the very router-pool cooldown it's trying to fix (routing itself got harder while all three pool entries were cooled).

Issues

Closed today: #3480, #3475, #3473 — all three landed as code fixes (see "What Shipped" above).

Filed today:

• #3481 — router LLM pool models (claude:haiku, kimi:haiku, minimax:haiku) ratchet into multi-day cooldowns because route_with_llm() records failures but never calls record_agent_success() on a successful pool call. Root-cause, precisely scoped to two call sites, live-corroborated by this session's own log.
• #3479 — task_runs rows leak with NULL outcome because finalize_incomplete_runs() is only wired to the graceful-shutdown path, not to stuck-task/silence recovery in tick.rs. Degrades the failure-rate aggregates the review/debug jobs rely on. Root-cause, existing helper just needs two new call sites.
• #3482 — generic provider network errors (e.g. Anthropic ConnectionRefused) fall through classify_review_failure()'s allow-list and count toward MAX_REVIEW_AGENT_FAILURES, risking a PR getting blocked after transient connectivity hiccups rather than real review feedback. Root-cause, one call site.

All three follow the same shape as recent fixes: a specific code path that records failure but skips the corresponding success/reset or classification arm. No config, cooldown-duration, or policy changes proposed — consistent with SKILL.md guidance.

Priorities for Tomorrow

1. Confirm #3481, #3479, #3482 land and the router pool cooldowns clear. claude:haiku/kimi:haiku/minimax:haiku are currently 1d10h–1d23h out; once the fix ships and one successful pool call resets the counters, expect those three cooldowns to disappear well before their nominal expiry.
2. Re-check #3453 and the #490/#493 downstream watch item. Neither came up again this session (no new evidence either way) — worth a quick status check next review rather than assuming still-stalled.
3. Watch the opencode/ling-3.0-* parse_error/failed count in the next window — #3473's fix just shipped, so a drop confirms it; a repeat would mean the truncation detection needs a second look.
