The headline: a quiet, self-healing day — one fix shipped, everything else recovered on its own

Window: 2026-08-21T23:02Z → 2026-08-22T23:01Z. One commit landed: 62b28042, closing #3541 (kimi/claude mid-stream disconnect messages — "Response stalled mid-stream" / "Connection closed mid-response" — were misclassified as generic AgentFailed/Unknown, triggering a full agent-wide exponential-backoff cooldown for what is a transient stream blip). The pattern behind that issue actually recurred twice more overnight (internal:157125, internal:157126, both kimi/opus, 03:08 and 08:21 UTC) before the fix landed — both tasks self-healed via the existing generic retry path and are done.

Yesterday's two stale-branch PRs (#3538, #3536) are unchanged: still OPEN/BEHIND, still blocked on the exact two pre-existing clippy errors (useless_format at response_handler.rs:582, needless_late_init at review.rs:444) that 9b9000f0 already fixed on main a day earlier. No new CI attempt has run against either branch since 2026-08-20T23:04Z — confirmed via gh run list. This is expected, by-design behavior (try_unblock_ci_failure_task() only clears on merge/close, not rebase); the operator decision to rebase-and-retry from yesterday's report still stands.

What Shipped (Last 24h)

Closed today: #3541 (filed and fixed same-window).

Still open, unchanged from yesterday:

• #3535 — opencode "not available in your country" misclassification. Fix already committed (ae8146bb); PR #3536 blocked on the same stale-branch CI issue as #3538, not on review.
• #3453 — pending-CI-status prose causing review parse errors (claude/sonnet specific), 24 days old, no new occurrence today.

Operational Health

Task Run Outcomes (last 24h)

Breakdown of the non-success rows, cross-checked against task_activity:

• kimi opus failed x2 (internal:157125, internal:157126) — the exact "response stalled mid-stream" pattern #3541 fixed today. Both tasks completed successfully after the generic retry recovered them; the fix landed after both occurrences, so future recurrences should get the lighter NetworkError treatment instead of the full cooldown.
• claude sonnet failed x4 — all silence detection set task to new following stuck-task recovery: no session found (internal:157099, 157127, 157137, 157158). This is the designed generic recovery path, not a new failure mode; all four tasks are done.
• opencode nemotron-3.5-lightning-free parse_error x2 (internal:157094 yesterday, internal:157098 today) — same review-run signature both times: the raw stdout is opencode's NDJSON event stream ending in a partial prose summary ("All checks pass. Let me summarize the review...") with step_finish reason:"unknown" and no trailing decision JSON. All of parse_review_response, infer_review_response, and the assistant-message rescue path came up empty both times — there's genuinely no JSON anywhere in the output, not a parser gap. Both tasks nonetheless completed successfully (done) via the generic re-review path. This is now two occurrences of the same model+shape in ~30h; not filing an issue yet since it self-heals cleanly and the underlying rescue chain already tried everything it reasonably can — watching for a third occurrence before treating it as an actionable model-selection or prompt problem.

task_activity (last 24h)

status_change 198, dispatch 78, push 56, branch_delete 56, routed 38, review_start 29, review_decision 27, pr_create 26, error 19, rerouted 3, timeout 1. The error count (19) is higher than yesterday's 5, but every single row traces to the two patterns above (mid-stream disconnects, now-fixed; and the two known parse_errors) plus their paired stuck-task recovery events — no unexplained entries.

Not evaluated — stale/inactive per policy (see repo CLAUDE.md).

Routing and cooldowns

No repeated-cooldown or silent-model-failure patterns beyond the ones already accounted for above. No evidence of the stuck-task reclaim race (#3518 → #3523 → #3526) recurring.

Backlog and stuck work

• internal:156996 (PR #3538) and 3535 (PR #3536) remain blocked on the stale-branch CI issue from yesterday — no change, operator rebase/retry still pending.
• bean and oblivion backlogs unchanged in shape: GitHub Actions billing failure blocks at merge time (correct per-task policy, operator-controlled), long-idle items already diagnosed in prior reviews as operator-controlled state.
• 25 tasks in the global queue, 21 blocked (all previously diagnosed), 2 in_progress (both today's daily-review jobs), rest done.

Policy alignment

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

Issues Filed Today

None. #3541 was filed and fixed in the same window before this review ran. The recurring opencode review parse_error is being watched, not filed, since both occurrences self-healed without operator intervention and the existing fallback chain (parse_review_response → infer_review_response → assistant-message rescue) already covers the reasonable recovery paths.

Priorities for Tomorrow

1. PRs #3536 and #3538 still need an operator rebase-and-retry — both are BEHIND main and will pass cleanly once rebased onto 9b9000f0, per yesterday's diagnosis (unchanged today).
2. Watch opencode/nemotron-3.5-lightning-free review runs for a third parse_error occurrence with the same "partial NDJSON summary, no decision JSON" shape before considering a targeted fix (e.g. steering that model away from review duty, or a stricter format nudge in the review prompt).
3. Confirm #3541's fix reduces mid-stream-disconnect cooldown severity on the next occurrence — no more full agent-wide backoff for what should be a short NetworkError retry.
4. #3453 remains the one other pre-existing open issue, now 24 days old, still no fresh occurrence to act on.
