[safe-output-health] 🏥 Safe Output Health Report - 2026-07-21

[github-actions[bot]]

Executive Summary

• Period: Last 24 hours (early-morning batch, ~03:xxZ–05:18Z)
• Runs Analyzed: 55 (all with a safe_outputs job present)
• Workflows Active: 24 distinct
• Safe Output Jobs Executed: 55
• Safe Output Jobs Failed (in scope): 0
• Error Clusters Identified: 0
• In-Scope Safe Output Job Success Rate: 100.0%

✅ Fully clean in-scope day. Every safe_outputs job succeeded. This recovers cleanly from 07-20 (94.6%, two Process Safe Outputs hard failures) — neither 07-20 failure signature recurred. It was also a write-rich day: 70 safe-output messages actuated across 30 write-runs with zero failed actuation.

Safe Output Job Statistics

Metric	Value
Runs with safe_outputs job	55
safe_outputs job success	55
safe_outputs job hard failure (in scope)	0
safe_outputs job cancelled/skipped	0
In-scope success rate	100.0%

Safe-output messages actuated (by type)

Message Type	Count	Result
create_pull_request_review_comment	24	✅ all success
submit_pull_request_review	19	✅ all success
add_comment	9	✅ all success
update_pull_request	6	✅ all success
create_issue	5	✅ all success
assign_to_agent	3	✅ all success
create_pull_request	2	✅ all success
create_discussion	2	✅ all success
Total	70	0 failed

30 runs actuated at least one write; 25 runs were read-only (no safe-output items).

Error Clusters

None. No safe_outputs job failed and no safe-output message failed actuation in this window. There are no error clusters to report.

Root Cause Analysis

Not applicable — zero in-scope failures.

• API-related issues: none observed in safe-output jobs.
• Data validation issues: none observed.
• Permission issues: none observed in safe-output jobs.
• Other: none.

Out-of-scope run-level failures (for context only)

Six runs finished at run-level failure, but in every case the failing job was the agent job — not the safe_outputs job — and each safe_outputs job still concluded success via clean handoff. These are handled by other monitors and are out of scope here:

Run	Workflow	Failed Job	safe_outputs
§29800808383	Code Simplifier	agent	✅ success
§29803065321	Smoke Claude	agent	✅ success
§29801597422	Smoke Copilot	agent	✅ success
§29801473729	Smoke Claude	agent	✅ success
§29802130442	Smoke Claude	agent	✅ success
§29801479276	Smoke Claude on Copilot	agent	✅ success

Why this matters (resilient-handoff positive)

All six agent-job failures are Smoke tests plus one Code Simplifier run — the same routine agent-side instability class seen throughout the historical record. Critically, the safe-output pipeline stayed healthy: each failed agent still handed off cleanly and its safe_outputs job succeeded. This is the desired failure-isolation behavior.

Recommendations

Critical Issues (Immediate Action Required)

None. No in-scope failures were detected.

Standing Observability Recommendation (carried over, unchanged)

• Pre-bundle the Process Safe Outputs step stdout into run artifacts. On the days when the safe_outputs job does hard-fail (e.g., 07-20, 07-11, 06-23/06-26), the exact error string is not recoverable because the step log is not pre-bundled, forcing family-level rather than variant-level attribution. Wiring this log into the downloadable artifact set would make future root-cause analysis exact. Priority: Medium (no active failure today, but recurrent blind spot on failure days).

Process Improvements

• Metrics blind spot (informational): the behavior_fingerprint.actuation_style continues to under-report writes performed via the bash safeoutputs CLI wrapper. This did not affect today's in-scope conclusions (all read directly from job_details[]), but the run-level SafeItemsCount remains an undercount for trend dashboards.

Work Item Plans

Work Item 1: Pre-bundle Process Safe Outputs step log

• Type: Enhancement (observability)
• Priority: Medium
• Description: When a safe_outputs job hard-fails, the exact failing-message error is unreadable because the Process Safe Outputs step stdout is not included in the pre-bundled run artifacts. This has blocked variant-level attribution on every JOB-layer failure day to date.
• Acceptance Criteria:
  • Process Safe Outputs step stdout/stderr is uploaded as a per-run artifact.
  • A subsequent audit can quote the exact error for a hard-failed safe_outputs job.
• Technical Approach: Add the step log to the artifact upload set in the safe-outputs job definition.
• Estimated Effort: Small
• Dependencies: None

Work Item 2: Exercise the review_path 422 Path-variant fallback

• Type: Investigation / test coverage
• Priority: Medium
• Description: The pr_review_buffer.cjs:554 Path-variant predicate fix remains UNVALIDATED for the 53rd consecutive audit. The review-comment path was exercised at scale today (24 create_pull_request_review_comment, 0 failures), but because no 422 'Path could not be resolved' occurred, the fallback branch was never triggered.
• Acceptance Criteria:
  • A synthetic/targeted case triggers a Path could not be resolved 422 and confirms the body-only fallback fires.
• Estimated Effort: Medium
• Dependencies: None

Work Item 3: Re-exercise Changeset Generator bundle-transport

• Type: Investigation
• Priority: High (highest-priority standing-open signature)
• Description: The Changeset Generator patch-format: BUNDLE push_to_pull_request_branch bundle-transport path has been ABSENT ~25 days (last actuation 2026-06-26) and remains the highest-priority unvalidated production signature. It was not present in this 55-run window.
• Acceptance Criteria:
  • A Changeset Generator run actuates a BUNDLE push and its safe_outputs job conclusion is captured.
• Estimated Effort: Small (needs the workflow to run)
• Dependencies: Workflow activation

Historical Context

Date	Runs	safe_outputs success	Failures (in scope)	Success rate
2026-07-21	55	55	0	100.0%
2026-07-20	37	35	2	94.6%
2026-07-19	12	12	0	100.0%
2026-07-18	14	14	0	100.0%
2026-07-17	82 triaged	—	0	100.0%

Trends

• Error-rate trend: Improving — back to 100% after 07-20's two hard failures. The 07-20 signatures (PR Code Quality Reviewer review-comment 422-family; Smoke Copilot all-handler) did not recur. PR Code Quality Reviewer ran 4× today, all success.
• Most common recurring issue (historical): Process Safe Outputs JOB-layer hard failures with unreadable exact error (observability gap) — not present today.
• Improvement since last audit: +5.4 pp (94.6% → 100.0%); 2 in-scope failures → 0.

Metrics and KPIs

• Overall Safe Output Success Rate: 100.0% (jobs) / 100.0% (70/70 messages)
• Most Reliable Job Type: all types 100% today
• Most Problematic Job Type: none (0 failures)
• Resilient handoff: 6/6 agent-job failures still produced a successful safe_outputs job

Next Steps

• No immediate action — safe-output pipeline is fully healthy.
• (Medium) Pre-bundle the Process Safe Outputs step log for exact attribution on future failure days.
• (Medium) Trigger the review_path 422 Path-variant to finally validate the pr_review_buffer.cjs:554 fallback (53rd audit unvalidated).
• (High) Re-exercise Changeset Generator bundle-transport (~25 days absent, highest-priority standing-open signature).
