DeepReport Intelligence Briefing - 2026-09-27

[github-actions[bot]]

🔍 Executive Summary

Incremental cycle since prior briefing #63658 (~6.2h window, 5 new discussions). This session's own deep-report repo-memory remains frozen at a 2026-09-08 snapshot despite the workflow having run continuously since (most recently 18:40Z yesterday, #63658, which itself flagged the same freeze) — recovered the true baseline directly from #63658's body, consistent with the standing, already-tracked persistence gap (#60773/#62435, twice declined not_planned). This narrow window's fleet signal is dominated by one real finding: agent-job failure rate is sustained at ~17% (2x the late-August baseline) for a second consecutive monitoring window, with two failure clusters still lacking dedicated trackers.

🚨 Top 5 Findings

• Fleet agent-job failure rate holding at 17.0%, essentially flat vs. 17.97% three days ago (2026-09-23) and roughly double the ~7-9% late-August baseline — the elevation has now persisted across 2+ monitoring windows with no landed remediation (Agent Job Health Report #63694).
• "Execute GitHub Copilot CLI" step failures remain the largest cluster (14 runs / 10 workflows this window, down from 24/13 on 09-23 but still the top failure signature) — already self-tracked as open issue #63695; not re-filed.
• New: "Redact secrets in logs" step fails post-execution across 6 workflows and 4 different engines (claude/codex/copilot/aider) — the model CLI step succeeds in every case, only the shared downstream redaction step fails, pointing to one common script/infra bug rather than 6 unrelated ones. Filed as a new issue this cycle.
• New: the conclusion job's "Handle agent failure" step itself fails while the agent job it reacts to reports success, in 3 runs across 3 different workflows — a confusing signal that risks other fleet-health monitors (including this one) double-counting or misattributing failures. Filed as a new issue this cycle.
• Avenger failed 100% of its 4 runs this window on the codex engine, but this is already covered by 4 open auto-filed [aw] Avenger failed stubs plus the standing Workflow Health tracker #63556 (3rd re-confirmation of the same npm-symlink root cause) — not re-filed.

✅ Actionable Agentic Tasks

This cycle filed 2 new issues (ceiling is 7; a genuinely light ~6.2h window with only 5 new discussions, most already healthy/chronic/self-tracked):

1. "Redact secrets in logs" step fails post-execution across 6 workflows, 4 engines — new issue filed, Medium effort (1-4h), cross-engine spread points to one shared post-processing bug recovering otherwise-successful runs.
2. Downstream "conclusion" job ("Handle agent failure" step) fails when the agent job succeeded — new issue filed, Quick-to-Medium effort (1-2h), removes a confusing false-positive signal from fleet monitoring.

Not fileable this cycle (reviewed and declined — already tracked, chronic, or too diffuse for a single fix):

3. "Execute GitHub Copilot CLI" step failure cluster (10 workflows) — already open as [agent-job-health] Recurring "Execute GitHub Copilot CLI" step failures across 10 workflows (untracked since 2026-09-23) #63695, not re-filed.
4. Avenger 100%-failure-this-window — already covered by 4 open auto-filed stubs + [Workflow Health] 3rd re-confirmation: avenger npm-symlink, metrics-collector model-provider, gpclean retired model still unfixe #63556 tracker, not re-filed.
5. Operational-value-study PR template's near-0% merge rate (6.2% this window, down from 21.5% the day before) — same chronic pattern investigated and downgraded to watch-only across many prior cycles (traced to a deliberate maintainer research campaign under ADR-55155); not re-filed without evidence it's become an unintentional recurring automated pattern.
6. Lockfile Statistics' "6 lockfiles missing standard guardrail safe-outputs" — the report itself couldn't name which 6, too vague to action without file-level identification.
7. Repo-memory persistence freeze for this very workflow — already tracked as [deep-report] push_repo_memory silently deletes repo-memory checkout while reporting false success #60773/[deep-report] Repo-memory persistence gap still reproduces post-Docker-migration despite #60773 closure #62435, twice declined not_planned; noted here as a standing limitation, not re-filed a 3rd time.

Methodology and data sources

• Baseline recovery: /tmp/gh-aw/repo-memory/default/deep-report/* files are frozen at a 2026-09-08 snapshot; recovered the true baseline directly from prior briefing DeepReport Intelligence Briefing - 2026-09-26 #63658's own body (created 2026-09-26T18:40:58Z) rather than trusting local memory files.
• Discussions: 5 new discussions since DeepReport Intelligence Briefing - 2026-09-26 #63658 read in full: Lockfile Fleet Statistics ([lockfile-stats] Lockfile Fleet Statistics — 2026-09-26 (298 workflows) #63672, healthy), Copilot PR Prompt Analysis ([prompt-analysis] Copilot PR Prompt Analysis - 2026-09-26 #63675, chronic operational-value pattern, improving), Daily Performance Summary ([daily performance] Daily Performance Summary - 2026-09-26 #63676, healthy/informational, 90-day view), Agent Job Health Report ([agent-job-health] Agent Job Health Report — 2026-09-26 (24h window) #63694, primary source for this cycle's findings), "copilot-arm64 was here" smoke test (copilot-arm64 was here #63729, routine pass, 1 chronic Google-domain firewall block already declined in prior cycles).
• Dedup: both filed candidates checked via mcp__github__search_issues (partially redacted by integrity policy on broad queries) plus keyword grep against the local 500-issue weekly snapshot (weekly-issues-data/issues.json) — no existing open issue found for either "redact secrets" cross-engine failures or "conclusion"/"handle agent failure" job semantics. The Copilot-CLI and Avenger candidates were confirmed already tracked via the same grep ([agent-job-health] Recurring "Execute GitHub Copilot CLI" step failures across 10 workflows (untracked since 2026-09-23) #63695, [Workflow Health] 3rd re-confirmation: avenger npm-symlink, metrics-collector model-provider, gpclean retired model still unfixe #63556, plus 4 open [aw] Avenger failed stubs) and correctly declined.
• Weekly issues: /tmp/gh-aw/agent/weekly-issues-data/issues.json (500 entries, last 7 days) via issues-analyst sub-agent: 178 open / 322 closed, 0 issues open >7 days, 90 unlabeled (dominated by the chronic [WIP] ... work in progress auto-stub pattern). Top labels: agentic-workflows (265), automation (81), cascade-suspected (69), cookie (56), code-quality (28). Top authors: github-actions[bot]/app/github-actions (478), ekbritecore (3), kamrulislamborbhuiya (2).
• Fleet logs: agenticworkflows logs not independently re-invoked this narrow ~6.2h cycle — Agent Job Health Report ([agent-job-health] Agent Job Health Report — 2026-09-26 (24h window) #63694, 206-run/24h sample) already gave comprehensive, fresher fleet-health signal than a fresh spot-check would.
• Repo-memory: written this cycle in case a future push lands; the persistence freeze itself remains a standing, already-tracked limitation ([deep-report] push_repo_memory silently deletes repo-memory checkout while reporting false success #60773/[deep-report] Repo-memory persistence gap still reproduces post-Docker-migration despite #60773 closure #62435), not re-filed.
