DeepReport Intelligence Briefing - 2026-08-07

[github-actions[bot]]

🔍 Executive Summary

The fleet is broadly healthy (100% safe-output success across 169 runs, 76.1% adjusted workflow success rate on 2026-08-06), but yesterday saw a single ~7-hour shared-infra hang that took down 43 workflows across 5 engines simultaneously, and this DeepReport's own repo-memory has been silently frozen at 2026-04-03 for over four months despite running daily. This cycle prioritizes reliability and observability gaps that no other specialized agent had yet turned into a tracked issue, since the code-quality lane is already well-served by 15+ open [Code Quality] issues from other agents. Urgent action: add a per-job hard timeout guardrail before the next shared-infra stall repeats the 2026-08-06 incident.

🚨 Top 5 Findings

• Fleet-wide ~7h hang (2026-08-06, 14:41–21:47 UTC): 68 of 91 failures (75%) across 43 workflows and 5 engines took 15 min–4.8h to fail instead of minutes — synchronized end-times point to one shared-infra event, not independent bugs. Burned 9,645 action-minutes / 1,075 AIC (63% of the day's total) for near-zero output. No per-job hard timeout exists to bound a recurrence.
• DeepReport's own memory has been broken for 4+ months: last_analysis_timestamp.md read 2026-04-03 at the start of this run despite daily discussion publishing since — the same staleness was flagged as a meta-finding in the 2026-08-05 cycle (DeepReport Intelligence Briefing - 2026-08-05 #50596) and never fixed. This run rewrote all four memory files with fresh 2026-08-07 data; next cycle should confirm the fix landed.
• Observability is mostly blind: only 1 of 14 (7.1%) sampled firewall/MCP-enabled runs retained access.log or MCP JSONL telemetry, despite the firewall/gateway being active in all 14 — egress and tool-call audit trails are effectively unavailable fleet-wide.
• Copilot Session Insights has had zero usable transcripts for 71+ consecutive days — find .../logs -name "*-conversation.txt" returns 0 files, forcing all analysis onto run-metadata fallback (no loop detection, no prompt-quality signal). Distinct from the already-fixed all-or-nothing artifact check ([aw-failures] Copilot Session Insights: all-or-nothing artifact check fails whole run when any sampled session log is missing #50273).
• Last cycle's issues resolved fast: 6 of the 7 issues filed by DeepReport on 2026-08-05 ([deep-report] Smoke Goose: model-proxy auth failing (401/404) + MCP gateway unreachable — new failure mode #50589–[deep-report] Auto-Triage only labels machine-generated 'report' issues — genuine bug reports (#50580, #50581) stay unlabeled #50595) are already closed within the week — only the MCP get_file_contents excerpt-mode request ([deep-report] MCP get_file_contents has no excerpt/range-read mode — full-file reads waste ~4,500 tokens on large files #50594) remains open. The dedup-and-quick-win approach is working.

Additional context: fleet metrics, prior open issues checked for dedup

• Fleet health (2026-08-06 full day): 378 runs, 91 failures, 75.9% raw / 76.1% adjusted success. prod-main: 84.8% (162/191).
• Issues: 111 open / 389 closed in the 7-day/500-issue sample. Top labels: agentic-workflows (183), automation (170), code-quality (59).
• Lockfiles: 276 compiled, 36.0 MiB total; 11 cron-collision pairs (22 workflows sharing an exact trigger minute).
• Copilot PR clustering (30d, 1,000 PRs): 74.3% overall merge rate; lowest cluster (image/container/digest keywords) merges at 58.8%, an outlier vs. the 79.2% high.
• Chronic copilot-sdk-driver-failures (open since 2026-06-02, 2+ months) remains the dominant non-incident baseline failure signature — not re-filed this cycle since it's a known, broader root-cause effort rather than a quick win.
• Dedup gate: checked the 111 open issues by keyword before filing each of the 7 tasks below; none of them overlap with existing open issues (verified individually, see each issue body for cross-references).

✅ Actionable Agentic Tasks

1. Add per-job hard timeout guardrail after the 2026-08-06 fleet-wide ~7h hang incident (43 workflows, 5 engines affected) — P0 reliability.
2. Fix DeepReport's own repo-memory persistence, stuck at 2026-04-03 for 4+ months despite daily runs — meta-reliability fix for this pipeline.
3. Fix firewall/MCP observability artifact retention — 92.9% of sampled runs are missing access.log/gateway.jsonl, blocking security auditing.
4. Add gh-aw-detection: true to 3 newly-flagged workflows (Deployment Incident Monitor, Deep Report, Daily Regulatory Report Generator) — quick win, recurring pattern.
5. Root-cause the 71+ day conversation-transcript fetch failure blocking Copilot Session Insights' loop-detection and prompt-quality analysis.
6. Investigate the lowest-merge-rate Copilot PR cluster (image/container/digest keywords, 58.8% vs. 74.3% fleet average) for a common blocker.
7. Stagger cron schedules for the 22 workflows that fire at the exact same minute as another workflow (11 colliding pairs) to reduce shared-infra contention risk.
