DeepReport Intelligence Briefing - 2026-10-02

[github-actions[bot]]

🔍 Executive Summary

This cycle is a narrow incremental sweep (only ~5h / 4 new discussions since the real prior briefing #64825, which this store's own memory had failed to record for ~24 days). The headline finding is self-referential: this repo-memory store has been silently frozen since ~2026-09-08 because push_repo_memory treats a missing artifact as a no-op "success" rather than a failure — root-caused and filed this cycle. Fleet health otherwise looks solid (5.42% 24h failure rate, improving from 17.97%), with one novel fleet-wide "Redact secrets in logs" post-success failure already self-tracked as #64867.

🚨 Top 5 Findings

• Repo-memory for Deep Report has been effectively stale since ~2026-09-08, despite many "successful" runs since: push_repo_memory exits success in <1s when the agent job's repo-memory-default artifact is missing (##[error]Unable to download artifact(s): Artifact not found), live-verified on run 36612476935 — filed as a new issue.
• 24h fleet failure rate improved to 5.42% (11/203 runs), down from 17.97% on 2026-09-23 — an improving trend, not a regression, per Agent Job Health [agent-job-health] Agent Job Health: fleet failure rate 5.42% (11/203 runs), 24h ending 2026-10-01 23:21 UTC #64866.
• Novel fleet-wide bug: "Redact secrets in logs" step fails after the agent CLI already succeeded, across 2 engines (Claude, Copilot) and 3 workflows (Deep Report, Daily Agent of the Day Blog Writer, Daily Ambient Context Optimizer) — already filed as [agent-job-health] [aw-failures] agent job: Redact secrets in logs step fails post-success on 3 workflows, 2 engines #64867 by the source report, not duplicated here.
• Copilot PR prompts correlate strongly with merge outcome: merged PRs average 186 words vs. 361 words for closed ones (~2x); bug fixes merge at 86.8% vs. 63.6% for feature additions and "investigate"-style multi-part prompts ([prompt-analysis] Copilot PR Prompt Analysis - 2026-10-01 #64842, 566 PRs over 30 days).
• Repo-memory infrastructure is mid-migration: push_repo_memory usage fell 40→35 workflows in just 2 days (2026-09-29→10-01) as new ledger_append/ledger_request_compaction safe-output types appear ([lockfile-stats] Lockfile Statistics Analysis — 2026-10-01 (301 workflows) #64836) — the artifact-handoff bug above may already be addressed by this migration for other workflows, but Deep Report itself hadn't moved yet as of the runs checked.

✅ Actionable Agentic Tasks

1. Filed — Fix push_repo_memory silent no-op on missing artifact. Root cause of this store's own ~24-day staleness; live-verified via job logs, not just report text.
2. Filed — Add scope/length guidance to Copilot PR prompt templates, based on the 2x prompt-length gap between merged and closed PRs in [prompt-analysis] Copilot PR Prompt Analysis - 2026-10-01 #64842.
3. Already tracked, not re-filed — "Redact secrets in logs" fleet-wide post-success failure: issue [agent-job-health] [aw-failures] agent job: Redact secrets in logs step fails post-success on 3 workflows, 2 engines #64867 (filed same-day by Agent Job Health [agent-job-health] Agent Job Health: fleet failure rate 5.42% (11/203 runs), 24h ending 2026-10-01 23:21 UTC #64866).
4. Declined, pattern-match only — chronic "Execute GitHub Copilot CLI" crash (5 runs/5 workflows): [agent-job-health] Agent Job Health: fleet failure rate 5.42% (11/203 runs), 24h ending 2026-10-01 23:21 UTC #64866 explicitly recommends letting the [aw] Failure Investigator (6h) workflow re-file rather than hand-filing a duplicate; followed that recommendation.
5. No action — informational only: Lockfile Stats [lockfile-stats] Lockfile Statistics Analysis — 2026-10-01 (301 workflows) #64836 (301 lockfiles, +1; fleet structural/permission/engine-distribution snapshot) — no anomalies warranting a new task this cycle.
6. No action — informational only: Daily Performance Summary [daily performance] Daily Performance Summary - 2026-10-01 #64844 (151 PRs merged/90d, 388 open issues vs. 3 open PRs, 0% discussions answered) — backlog imbalance noted but not newly actionable without a fuller trend baseline (prior-cycle comparison unavailable due to the memory gap above).
7. Not pursued this cycle: the narrow ~5h window and degraded issue-search dedup confidence (integrity-filtered queries, same limitation [agent-job-health] Agent Job Health: fleet failure rate 5.42% (11/203 runs), 24h ending 2026-10-01 23:21 UTC #64866 reported) meant only 2 tasks cleared the bar for a verified, non-duplicate, high-value quick win. Full discussion-mining for code-quality tasks (step 2.7) was skipped this cycle given the window only contained 4 non-code-quality-focused reports; recommend the next cycle re-run it once repo-memory persistence (task 1) is confirmed fixed.

View Full Details — memory staleness and investigation trail

This store's last_analysis_timestamp.md claimed the last cycle ran 2026-09-07/08, but a live query of discussions.json for "DeepReport Intelligence Briefing" titles found #64825 from 2026-10-01T18:45:51Z — a ~24-day undetected gap. Investigating why led to pulling 40 runs of Deep Report's own workflow history via the logs tool: 22/40 runs showed failure_kind: driver_exit (now understood, per #64866, to likely be the same "Redact secrets in logs" bug), but critically, even conclusion: success runs (e.g. 2026-09-29T18:29:58Z, run 36612476935) showed push_repo_memory's "Download repo-memory artifact" step logging ##[error]Unable to download artifact(s): Artifact not found for name: repo-memory-default, followed by "Memory directory not found in artifact" and a same-second "success" conclusion. Cross-checked against git log on the memory/deep-report branch, whose last real commit (d09329a, run 34195380008) matches the ~2026-09-08 date — confirming the artifact-gap bug, not a reporting fluke, is why this store stopped advancing.

This finding is now recorded in repo-memory (known_patterns.md, flagged_items.md) so future cycles can verify the fix landed rather than re-discovering the same gap.
