[deep-report] Reconcile self-contradictory Safe Output Health Monitor cadence readings (600.1h vs 48.02h) and confirm the missed 2026-10-07 ru #66811

Description

The Safe Output Health Monitor workflow is producing self-contradictory cadence-detection readings on consecutive days: the 2026-10-07 audit reported 600.1h stale with last success dated 2026-09-12 ([discussion #66680-era cycle]), while the 2026-10-08 audit (discussion #66785) reports only 48.02h stale with last success 2026-10-06T04:27:50Z (run 37413824658). These cannot both describe the same continuous run history, which means the cadence-checker's run-selection query is unreliable. Separately, no trace of a 2026-10-07 run of "Safe Output Health Monitor" appears anywhere in that audit's 324 cached run directories, so it's unknown whether the 2026-10-07 scheduled trigger simply never fired or ran and failed silently before publishing.

Expected Impact

A monitor that can't reliably report its own cadence undermines trust in every other finding it publishes (including today's genuinely good news — the first zero-failure day in 21 tracked audit days). Fixing the run-selection query (and/or adding a secondary independently-computed cadence signal, e.g. counting actual create_discussion calls attributed to this workflow) prevents future false "600h stale" alarms and false "all clear" readings.

Suggested Agent

Maintainer investigation, or the safe-output-health workflow's own maintainers — needs a human/agent with access to the actual GitHub Actions run history API for the "Safe Output Health Monitor" workflow (outside the sandboxed audit's local log cache) to compare against the two reported numbers.

Estimated Effort

Medium (1-4 hours) — requires comparing live Actions run history against the cadence-checker script's query logic, plus a small fix or a cross-check signal.

Data Source

DeepReport Intelligence analysis, 2026-10-08 incremental cycle (~06:45 UTC), synthesizing discussion #66785 (Safe Output Health Monitor, run 37727673629). Local dedup check of the last-7-days issues snapshot found no existing open issue tracking this specific discrepancy (note: live search_issues queries against this repo returned fully integrity-filtered empty results during this cycle, same limitation LintMonster's #66761 report hit — if a duplicate is found after the fact, please close this one and link it).
