[safe-output-health] Safe Output Health Report - 2026-06-06 (6th consecutive clean day)

[github-actions[bot]]

Executive Summary

Sixth consecutive clean day. Zero safe-output job hard failures across the captured window. All 8 observable safe_outputs jobs and all 18 processed messages succeeded (Failed: 0 in every Processing Summary). The streak now runs 2026-06-01 (full day, 84 jobs) → 06-02/03/04/05/06 (partial early-morning windows), all 100%.

• Period: Last 24h, captured window 2026-06-06 ~05:02Z–05:29Z (early-morning batch)
• Runs analyzed: 11 directories (10 production + 1 self-monitor)
• Workflows active: 9 distinct (Smoke CI x3, PR Sous Chef, Step Name Alignment, Sergo, Documentation Noob Tester, Agent Persona Explorer, Issue Monster, Deep Research)
• Observable safe-output jobs: 8 → 8 success, 0 failure
• Messages processed: 18 → 10 successful + 8 by-design skips, 0 failed
• Error clusters identified: 0 new; 0 active

Window caveat: Pre-bundled artifacts contained only prompts + base repo snapshot + aw_info. Downstream safe_outputs job logs (including each run's Process Safe Outputs step) were fetched per-run via the audit MCP tool. 3 runs (Issue Monster, Smoke CI 27053741915, self) had agent jobs still in_progress at capture, so their safe-output jobs were not observable. Daily totals are a lower bound.

Safe Output Job Statistics

Job Type	Executions	Failures	Success Rate
create_discussion	3	0	100%
create_issue	2	0	100%
noop	4	0	100%
missing_tool	1	0	100%
upload_asset (skipped-standalone, by-design)	8	0	n/a

Critical Issues

None. No API errors, no parsing/validation errors, no permission failures, no timeouts in any safe-output job. error_count = 0 and mcp_failures = 0 across all analyzed runs.

Notable Positive: failure-path handoff is healthy

The Deep Research Agent run 27053170902 had its agent job fail after 15.6m with "numerous permission denied errors" (an agent-job failure — out of scope for this monitor). Despite that, its safe_outputs job still ran (15.0s) and cleanly processed the single missing_tool fallback message the agent emitted (Total 1, Successful 1, Failed 0). This is exactly the intended graceful-degradation behavior: an agent failure still produces a clean safe-output handoff.

Low-Severity Observations (cosmetic, no actuation impact)

1. renderMarkdownTemplate "Fence count mismatch" — now seen in a PRODUCTION run

Documentation Noob Tester 27053254853 create_discussion #37253 logged ##[warning][renderMarkdownTemplate] Fence count mismatch: input had 4 fence marker(s), output has 2. Cause: a false-condition conditional block containing a fenced "tip" was removed, unbalancing the fence accounting. Discussion created successfully (Failed: 0).

Worth flagging: this contradicts the 2026-06-04 conclusion that the warning is "smoke-template-only / absent from production." It fires on the production Doc Noob create_discussion template whenever renderMarkdownTemplate strips a conditional block whose body contains an unbalanced code fence. Recommend the template renderer treat fences inside removed conditional blocks atomically so the fence count stays balanced.

2. create_discussion category config drift — Agent Persona Explorer

Agent Persona Explorer 27053452498 create_discussion fell back to Announcements (fallback-announcement) because its configured discussion category does not exist in the repo's category set. By-design fallback, Failed: 0. Contrast: Sergo (#37252) and Documentation Noob Tester (#37253) both used category Audits cleanly in the same window — so Audits resolves fine; the drift is specific to agent-persona-explorer's configured category name. Recurring config-drift theme first noted 2026-06-03. Recommend reconciling that workflow's create_discussion.category against the repo's actual categories. No handler fix needed.

Recurring Cluster Status

Cluster	Today	Status
review_path_unresolved_422 (Path variant)	not exercised	UNVALIDATED 10th consecutive audit — no PR-reviewer workflows ran in window
assign_to_agent_literal_issue_number_guess	not observable	Issue Monster agent in_progress at capture; latent
target_star_review_comment_no_pr_number	not exercised	latent
target_star_add_comment_no_item_number	not exercised	latent
cancellation_counter_mislabeled_code_push	not exercised	latent
own_pr_review_event_422_retry (healthy)	not exercised	by-design self-recovery

Recommendations

1. (Carry-over, rejig docs #1 outstanding) Land the one-line predicate fix at actions/setup/js/pr_review_buffer.cjs:554 — change to (errorMessage.includes("Line could not be resolved") || errorMessage.includes("Path could not be resolved")) && comments.length > 0 and add a matching unit test. The Path-variant body-only fallback has now been unvalidated for 10 consecutive audits (no 422 has fired to exercise it since the 2026-05-27 regression; the happy path was confirmed clean on 06-04). Low urgency given no recurrence, but it remains the single open remediation.
2. (Low) Reconcile agent-persona-explorer workflow create_discussion.category to an existing repo category (e.g. Audits) to stop the silent Announcements fallback.
3. (Low, cosmetic) Fix renderMarkdownTemplate fence accounting so removed conditional blocks don't unbalance the fence count — and retire the stale "smoke-template-only" note, since it now reproduces in production.

Historical Context

Sixth consecutive clean day. The safe-output subsystem has had 0 hard failures since the 2026-05-31 assign_to_agent cluster (which did not reproduce on 06-01 or 06-05). The only standing item is the unvalidated Path-variant fallback predicate. Today added a useful positive data point (agent-failure → clean safe-output handoff) and surfaced no new failure clusters.
