🏥 Safe Output Health Report — 2026-06-02

Executive Summary

A clean day for safe-output jobs. Every safe-output job in the captured window completed with Failed: 0 and zero ##[error] annotations. This is the second consecutive clean day (following 2026-06-01). One by-design soft recovery fired and self-healed.

⚠️ Window caveat: the pre-downloaded log set is a partial early-morning batch — 18 run directories spanning runs from ~05:05Z to ~05:47Z on 2026-06-02. This is far smaller than recent full days (2026-06-01 saw 84 safe-output jobs). The findings below are sound for the captured window, but the daily counts are a lower bound, not a full-day total.

• Period: captured window 2026-06-02 ~05:05Z–05:47Z (partial)
• Run directories analyzed: 18
• Safe-output jobs executed: 14
• Safe-output messages processed: 24
• Safe-output messages failed: 0
• Soft recoveries (by-design, net Failed: 0): 1
• Error clusters identified: 0
• Overall safe-output success rate: 100%

Safe Output Job Statistics

Per-handler breakdown of the recorded write side-effects across the 14 jobs (all succeeded). The remaining messages were noop / collected-separately items.

Handler type	Messages	Failures	Success Rate
update_pull_request	3	0	100%
add_comment	3	0	100%
submit_pull_request_review	3	0	100%
create_discussion	2	0	100%
create_issue	1	0	100%
create_pull_request	1	0	100%
create_pull_request_review_comment	1	0	100%
create_check_run	1	0	100%
noop (+ uncounted)	~9	0	100%
Total	24	0	100%

Error Clusters

None. No safe-output job recorded a hard failure (Failed: 0 on all 14 jobs; no ##[error] in any safe_outputs step).

Soft recovery (1) — by-design, self-healed

update_pull_request update-branch merge conflict (non-fatal)

• Run: PR Sous Chef — §26800747813 (copilot)
• What happened: the update_pull_request message requested update_branch on PR [jsweep] Clean validate_memory_files.cjs #36404. GitHub returned 422 (merge conflict between base and head, Retryable: false).
• Handling: the handler logged a ##[warning] marked non-fatal and continued. The body append still succeeded → Successfully updated pull request #36404.
• Outcome: Processing Summary Total messages: 4, Successful: 4, Failed: 0.
• Verdict: documented graceful-degradation path, not a failure. No action required.

PUT /repos/github/gh-aw/pulls/36404/update-branch - 422 ...
##[warning]Failed to update pull request #36404 branch from base (non-fatal): ERR_API ... merge conflict between base and head ... Retryable: false
✓ Message 1 (update_pull_request) completed successfully

Recurring Cluster Status

All previously-tracked clusters were latent or not reproduced this window.

Cluster	Status this window
review_path_unresolved_422	Not exercised (neither variant). 3 submit_pull_request_review messages submitted cleanly, no 422.
assign_to_agent_literal_issue_number_guess_unresolved	Not exercised (no assign_to_agent messages).
target_star_review_comment_no_pr_number_fallback	Not reproduced (the 1 review-comment carried valid PR context).
target_star_add_comment_no_item_number_fallback	Not reproduced (all add_comment carried explicit #36404).
cancellation_counter_mislabeled_code_push_failed	Not exercised (no WTD3 abort).

Standing Recommendation (unchanged, #1 priority)

The only outstanding remediation remains the review_path_unresolved_422 Path variant fix, now unvalidated for the 6th consecutive audit because no Path-anchored review-comment 422 has occurred in production since the 2026-05-27 regression.

• File / location: actions/setup/js/pr_review_buffer.cjs:554
• Problem: the body-only fallback predicate matches only "Line could not be resolved", not "Path could not be resolved". The Line variant self-heals reliably; the Path variant would hard-fail.
• Fix (one line): broaden the predicate to
  (errorMessage.includes("Line could not be resolved") || errorMessage.includes("Path could not be resolved")) && comments.length > 0
• Lock-in: add a pr_review_buffer.test.cjs case mirroring the existing Line test but using "Path could not be resolved".
• Effort: Small. The fallback retry block already handles both cases identically once entered.

Out-of-Scope Notes (not safe-output-job health)

Observed but excluded from this audit

• Detection-job conclusion=failure outputs in several runs → detection-monitoring scope.
• Agent-job ✗ shell-step failures (PR Sous Chef branch/checkout steps, Test Quality Sentinel, Documentation Noob Tester) → agent-job-monitoring scope.
• [entrypoint][WARN] Failed to transfer ... safeoutputs ownership to chroot user appears in nearly every agent job — pre-existing benign sandbox warning; did not affect safe-output processing (all Failed: 0). Infra/sandbox scope.

Historical Context & Trend

• Trend: stable/healthy. Message success rate 100% (= 2026-06-01); run-level job success 100%.
• Most reliable handlers this window: all 9 exercised handler types at 100%.
• Most problematic handler: none.
• The Line-variant body-only fallback (heavily validated 2026-05-22 → 2026-06-01) was not triggered this window — reviews submitted cleanly.
• No new clusters identified.

Next Steps

• Land the one-line pr_review_buffer.cjs:554 Path-variant predicate fix + unit test (carry-over, rejig docs #1 priority).
• Re-audit on the next full-day window to confirm the clean streak holds at production volume (today's window was partial).
• Continue watching for the latent target_star_* and assign_to_agent clusters when those handlers are next exercised.
