[aw-maintenance:failures-investigator] Failure Report: github/gh-aw-actions (24h window)

- **Target repository**: `github/gh-aw-actions`
- **Window**: last 24 hours (from 2026-09-02T21:44:44Z)
- **Failed agentic runs**: 3
- **Failure buckets**: 2 (P0: 0, P1: 1, P2: 1)
- **Agentic workflows in repository**: 1

### Failure Buckets

| Severity | Workflow | Error signature | Runs | Tracking |
|---|---|---|---|---|
| P1 | Daily Runtime Threat Scan | activation step "Check compile-agentic version" fails: `Blocked compile-agentic version: v0.83.1 is in the blocked versions list` | 2 | new issue |
| P2 | Daily Runtime Threat Scan | agent job fails during "Execute GitHub Copilot CLI" step; captured tail shows only MCP gateway startup/tool-registration logs, no explicit error line | 1 | needs evidence |

### Resolved Buckets

none

Evidence

**Bucket 1 — blocked compile-agentic version**
- Representative run: https://github.com/github/gh-aw-actions/actions/runs/33807348028 (also 33802522237)
- Failed job: `activation`, failed step: `Check compile-agentic version`
- Log excerpt: `##[error]Blocked compile-agentic version: v0.83.1 is in the blocked versions list. Update gh-aw to the latest version and recompile your workflow.`
- The check fetches `https://raw.githubusercontent.com/github/gh-aw-actions/main/.github/aw/compat.json` and rejects the compiled version (`GH_AW_COMPILED_VERSION: v0.83.1`) baked into the lock file. Both recent runs used the same compiled version and both were blocked at the activation gate before the agent job ran.

**Bucket 2 — agent step failure with insufficient captured evidence**
- Run: https://github.com/github/gh-aw-actions/actions/runs/33717072313
- Failed job: `agent`, failed step: `Execute GitHub Copilot CLI`
- The 50-line truncated tail only contains MCP gateway startup output (`github: connected`, `safeoutputs: connected`, tool schema dump) with no `##[error]` line visible, so no root cause can be established from the payload alone. Marked as needing deeper log evidence (e.g. `agenticworkflows-audit` on this run) before a fix issue can be filed.

### Next Steps

1. Bump the pinned `gh-aw`/`compile-agentic` version in `github/gh-aw-actions` past v0.83.1 and recompile the `Daily Runtime Threat Scan` workflow so activation stops rejecting it against `.github/aw/compat.json`.
2. Investigate the isolated agent-step failure in run 33717072313 with full (non-truncated) logs to determine a root cause before opening a fix issue.

Start with the Daily Runtime Threat Scan workflow and its lock file, then compare the pinned gh-aw/compile-agentic version with .github/aw/compat.json in github/gh-aw-actions. Recompile the workflow after updating the blocked version, and use the full logs or agenticworkflows-audit for run 33717072313. Done means activation succeeds and the remaining agent failure has an identified cause.
