Replaced non-writable file for secret redaction: /tmp/gh-aw/sandbox/firewall/audit/awf-resolved-config.json\\n ##[warning]Replaced non-writable file for secret redaction: /tmp/gh-aw/sandbox/firewall/audit/docker-compose.redacted.yml\\n ##[warning]Replaced non-writable file for secret redaction: /tmp/gh-aw/sandbox/firewall/audit/image-manifest.json\\n ##[warning]Replaced non-writable file for secret redaction: /tmp/gh-aw/sandbox/firewall/audit/policy-manifest.json\\n ##[warning]Replaced non-writable file for secret redaction: /tmp/gh-aw/sandbox/firewall/audit/sensitive-paths.json\\n ##[error]ERR_VALIDATION: Secret redaction failed: ERR_VALIDATION: Failed to remove artifact source after secret redaction failed\\n ```\\n The copilot-engine instance ([37676391386](https://github.com/github/gh-aw/actions/runs/37676391386)) shows the identical signature, one line earlier: `##[warning]Replaced non-writable file for secret redaction: /tmp/gh-aw/mcp-logs/safeoutputs/server.log` → `##[error]ERR_VALIDATION: Secret redaction failed: ERR_VALIDATION: Failed to remove artifact source after secret redaction failed`.\\n- **Suspected root cause:** `redact_secrets.cjs` replaces non-writable sandbox/firewall-audit files in place (logged as warnings), then a later step tries to remove the original artifact source and fails — likely because the replacement left a file with different ownership/permissions, or a race between the firewall sandbox teardown and the redaction step's cleanup. The agent's own execution always completed fine in all 4 cases; only this post-processing step fails, but it still fails the whole job.\\n- **Blast radius:** fleet-wide / engine-agnostic. Every workflow run that hits this scenario (apparently tied to certain sandbox/firewall-audit file states) will fail at the finish line even though the actual agentic work succeeded.\\n- **Recommended action:** file created (see below) — the fix likely belongs in `redact_secrets.cjs` or the firewall-audit artifact handling, making artifact-source removal tolerant of files it just rewrote in place.\\n\\n**2. `Execute GitHub Copilot CLI` — engine timeout (`agentic_engine_timeout`)**\\n- **Count:** 2 runs, 2 distinct workflows — Impeccable Skills Reviewer, Matt Pocock Skills Reviewer (both `pull_request`-triggered, both copilot engine)\\n- **Representative run:** [37682943473](https://github.com/github/gh-aw/actions/runs/37682943473)\\n- **Evidence:** conclusion-job telemetry: `agent.execution categories=[\\\"agentic_engine_timeout\\\"] errorCodes=[] errorTypes=[] exitCode=0`\\n- **Suspected root cause:** Copilot CLI engine exceeding its step/turn timeout on these two PR-review workflows; exit code 0 suggests a clean timeout cutoff rather than a crash.\\n- **Blast radius:** copilot engine only, 2 PR-review workflows so far.\\n- **Recommended action:** no open issue found; worth a follow-up if it recurs — consider raising the per-turn timeout or trimming prompt/tool scope for these two reviewer workflows.\\n\\n**3. `Execute GitHub Copilot CLI` — HTTP 429 rate limit**\\n- **Count:** 1 run — Daily Reliability Review (schedule-triggered, copilot engine)\\n- **Representative run:** [37699051771](https://github.com/github/gh-aw/actions/runs/37699051771)\\n- **Evidence:** `agent.execution categories=[] errorCodes=[429] errorTypes=[\\\"rate_limit\\\"] exitCode=1`\\n- **Note:** this is a *different* root cause from cluster 2 above, despite failing at the same step name — do not conflate the two \\\"Copilot CLI\\\" failures.\\n- **Blast radius:** single workflow, single run. Likely transient; monitor for recurrence.\\n\\n**4. Unconfirmed-root-cause singletons**\\n- Agentic Workflow Audit Agent — failing step \\\"Start MCP Gateway\\\" ([37688836213](https://github.com/github/gh-aw/actions/runs/37688836213), codex)\\n- Daily BYOK Ollama Test — failing step \\\"Warm up model\\\" ([37696303776](https://github.com/github/gh-aw/actions/runs/37696303776), copilot — expected flakiness surface for a workflow that tests local Ollama model warm-up)\\n- Daily Cache Strat
