[aw-failures] [aw] Failure Investigator Report — 2026-08-13 19:10 UTC (6h)

[github-actions]

Executive summary

• Fix the Crush CLI sandbox PATH gap in Daily Code Metrics — deterministic ENOENT on Execute Crush CLI, now 2 of the last 2 daily runs (2026-08-12, 2026-08-13), and it has zero existing tracking. New sub-issue filed below.
• Escalate [aw-failures] [P0] Failure-Investigator log capture grabs post-job cleanup tail, not the actual error #52501, don't re-file it — the log-capture-truncation bug hit 3 of the 5 failures analyzed this window (Design Decision Gate ×2, §31729681682 and §31726889123; Linter Miner, §31726936445) — same signature already tracked, still unfixed, still blinding this very investigation.
• Take no action on Smoke Gemini — single 503 RetryableQuotaError after 10 built-in retry attempts (§31732491740); transient upstream Gemini outage, isolated occurrence, no code defect.

Failure cluster table

Cluster	Severity	Workflow(s)	Runs (this window)	Tracking status
Crush CLI ENOENT in sandboxed exec	P0	Daily Code Metrics and Trend Tracking Agent	§31731856180 (2026-08-13), §31628722200 (2026-08-12)	Untracked — sub-issue filed
Log capture grabs post-job cleanup tail, not the error	P0 (recurring)	Design Decision Gate 🏗️, Linter Miner	§31729681682, §31726889123, §31726936445	Tracked — #52501 (still open, still recurring)
Gemini API 503 service-unavailable after 10 retries	P2	Smoke Gemini	§31732491740	Untracked — not actionable, isolated/transient

Evidence

Crush CLI ENOENT — install/verify succeed, execution fails (click to expand)

agentic-workflows audit on both failing runs confirms the same signature and step position:

• Both runs: Install Crush → success, Verify Crush CLI installation → success, Execute Crush CLI → failure.
• Failing run's own log: [crush-harness] spawnSync crush ENOENT, immediately after the harness logs `awf-reflect: provider=github mapped to endpoint provider=copilot baseUrl=(apiproxy/redacted) and the proxy sidecar reports all 4 listeners (openai/anthropic/copilot/gemini) started and passed key validation.
• audit-diff against the last successful run (§31419941312, 2026-08-10) shows the failed run did reach api.githubcopilot.com and api.openai.com through the proxy (2 and 3 allowed calls) — so the sandbox network path is healthy. The failure is specifically the harness's spawnSync('crush', ...) call not finding the binary at execution time.
• Conclusion: the binary is installed and verified on the runner host, but the sandboxed/chroot exec environment used by the Execute Crush CLI step does not have it on PATH (or doesn't have the install location bind-mounted). This is a harness/sandbox integration bug, not a network or install-script bug.

Log-capture truncation — pattern confirmed 3x more today (click to expand)

All 3 runs show truncated_error_logs[].tail_lines containing only post-failure git/cleanup/OTLP-teardown output (e.g. Post job cleanup., Cleaning up /tmp/gh-aw..., git config --local --unset-all) — never the actual ##[error] line from the failing step (Execute Claude Code CLI / Execute GitHub Copilot CLI). This is the exact defect #52501 already describes and proposes a fix for (anchor capture to the failing step's log offset, not the job's absolute tail). No new issue needed — this just adds 3 more confirming runs to that existing report.

Existing issue correlation

Cluster	Match	Action taken
Log-capture truncation	#52501 (high confidence — identical signature and remediation already proposed)	Left open, no duplicate filed; new run IDs noted above
Crush CLI ENOENT	No match across 22 open agentic-workflows issues	New sub-issue filed (P0)
Gemini 503	No match, and not warranted — single transient occurrence with exhausted retries	No issue filed

No open issues were found to be fixed or stale based on this window's evidence; none were closed.

Fix roadmap

• P0: Fix the Crush CLI sandbox PATH/mount gap — see sub-issue below. Blocks Daily Code Metrics 2 days running.
• P1: None new this window.
• P2: Monitor Gemini API 503 rate — no fix needed unless it recurs across multiple runs.

Sub-issues created

• P0 — Crush CLI binary unreachable inside sandboxed exec environment (ENOENT) despite passing host-level install/verify — see linked sub-issue.

Update — 2026-08-15 06:00-07:00 UTC investigation (6h)

Fix the two new P1s below first — they're isolated so far but both have zero graceful-degradation, meaning the very next occurrence looks identical.

Failure cluster table

Cluster	Severity	Workflow	Run	Status
Bun segfault (Claude harness)	P0	Failure Investigator (self)	§31855680444	Duplicate of #51984 — closed #52807, updated #51984 (now 3 workflows)

Claude Code CLI 15-min timeout loop	P1	Go Logger Enhancement	§31861677993	New — sub-issue created, see below
Cross-repo safe-output rejected	P2	PR Sous Chef	§31865458995	New, isolated, low severity — noted here only, no sub-issue (see below)
Critical vuln/license gate fired	P2 (informational)	Daily Container Image Security Scan	§31867321216	Real security finding, gate working as designed — no fix issue

Evidence and existing-issue correlation

• [aw-failures] [P0] Bun runtime segfault crashing Claude Code CLI — now hitting 2 workflows #51984 (Bun segfault): now confirmed hitting a 3rd workflow (Avenger x2 + Failure Investigator x1). Closed duplicate [aw] [aw] Failure Investigator (6h) failed #52807 into it.
• [aw-failures] [P1] Anthropic proxy connection-refused/retry-exhaustion now hitting 3 workflows after ~10 retries #52459 (Anthropic ConnectionRefused): now confirmed hitting a 4th workflow. Also reproduced the compounding --continue disabled permanently harness bug on attempt 2 (failure_reason=harness_retry_path_invalid) — same secondary bug documented in [aw-failures] [P0] Bun runtime segfault crashing Claude Code CLI — now hitting 2 workflows #51984.
• [aw-failures] [P1] PR Sous Chef: Start DIFC Proxy step fails with no captured root cause #52502 (PR Sous Chef DIFC Proxy): NOT the same failure as this window's PR Sous Chef run — that one failed at a different step (Process Safe Outputs, not Start DIFC Proxy) with a fully-visible root cause (cross-repo resolve_pull_request_review_thread rejected for scrapy/scrapy, not in the allowed-repos list). Isolated/low severity, treated as expected security-boundary behavior rather than a bug — no sub-issue filed, flagging here for visibility only.
• audit-diff on the Go Logger Enhancement failure vs its last success (§31768069259) shows 0 firewall/network anomalies and 18 vs 693 GitHub API rate-limit core points consumed — confirms the failure is a task/tooling stall, not an infra or connectivity regression.

New sub-issues filed under this report: see linked sub-issues list on this issue.

Fix roadmap

• P0: none new this window (Bun segfault already tracked in [aw-failures] [P0] Bun runtime segfault crashing Claude Code CLI — now hitting 2 workflows #51984, consolidated).
• P1: land the anthropic-proxy health-probe fix ([aw-failures] [P1] Anthropic proxy connection-refused/retry-exhaustion now hitting 3 workflows after ~10 retries #52459) and the --continue harness bug together since they compound; fix the Crush cache-miss 401 and the Go Logger timeout-loop guard (new sub-issues).
• P2: no action needed — PR Sous Chef cross-repo rejection and the container-scan vulnerability gate are both working as designed.

Update — 2026-08-15 11:00-13:00 UTC investigation (6h)

Fix the new Crush harness DNS regression first — it's a fresh P0 with zero graceful degradation, and it landed the same morning as the fix for #52571.

Failure cluster table

Cluster	Severity	Workflow	Run	Status
Crush harness resolves unresolvable api-proxy hostname for chat completions	P0	arXiv Paper Researcher	§31874781096	New — sub-issue filed, see below
Copilot billing 403 (authentication_failed)	P1 (recurring)	Daily Max Ai Credits Test	§31881546024	Matched #51589 — updated (now day 7, escalated)

Evidence and existing-issue correlation

• Crush DNS regression (new): agent-stdio.log shows the reflect probe resolving baseUrl=(host.docker.internal/redacted) correctly, then the actual chat-completions POST failing with dial tcp: lookup api-proxy on 172.17.0.0:53: no such host. The same workflow failed the prior 4 consecutive days (08-11 → 08-14) with a *different* signature, spawnSync crush ENOENT(tracked as #52571, closed by PR #52576 merged 2026-08-15T05:21:29Z). This run is the first scheduled run after that merge — the failure mode changed in the same code path, indicating PR #52576 traded one bug for another rather than fully fixing the Crush/api-proxy path.audit-diff` vs the last success (08-10, §31372099754) shows no firewall/domain blocks, ruling out a policy rejection.
• Copilot billing 403 (recurring): Identical signature to [aw-failures] [P1] Fix Copilot billing 403 masking Daily Max Ai Credits Test — 5+ consecutive daily failures #51589's original report, now a 7th consecutive day. No drift — still authentication_failed HTTP 403 on the very first request, still never reaching the credit-limit guardrail this test exists to validate.
• Both failures in this window's prefetch payload came with only MCP/safeoutputs-boilerplate truncated_error_logs (no captured ##[error] line) — this is another instance of the log-capture-truncation defect tracked in [aw-failures] [P0] Failure-Investigator log capture grabs post-job cleanup tail, not the actual error #52501, still unfixed, still forcing direct agent-stdio.log/audit pulls to get real evidence.

New sub-issues filed under this report: see linked sub-issues list on this issue.

Fix roadmap

• P0: land the Crush harness baseUrl-consistency fix (new sub-issue) — blocks arXiv Paper Researcher outright, day after the ENOENT fix.
• P1: escalate [aw-failures] [P1] Fix Copilot billing 403 masking Daily Max Ai Credits Test — 5+ consecutive daily failures #51589 to the Copilot billing/proxy owner directly — 7 days of silent test invalidation is past the "monitor" stage.
• P2: none new this window.
