[aw-maintenance:failures-investigator] Failure Report: gh-aw compiled version v0.82.13 blocked (24h window)

- **Target repository**: `githubnext/gh-aw-workshop`
- **Window**: last 24 hours (from 2026-09-03T02:48:13Z)
- **Failed agentic runs**: 44
- **Failure buckets**: 1 (P0: 1, P1: 0, P2: 0)
- **Agentic workflows in repository**: 22

### Failure Buckets

| Severity | Workflow | Error signature | Runs | Tracking |
|---|---|---|---|---|
| P0 | All agentic workflows (e.g. `Workshop Student Simulator`, `Workshop Builder`, `Workshop Author`) | `##[error]Blocked compile-agentic version: v0.82.13 is in the blocked versions list. Update gh-aw to the latest version and recompile your workflow.` at the `activation` job's "Check compile-agentic version" step | 44 | new issue |

### Resolved Buckets

none

Evidence

All 5 detailed sample failures (and, by log signature, all 44 failed run IDs in the window) fail identically in the `activation` job at the "Check compile-agentic version" step, before any agent code executes:

- Run `33830050300` — `Workshop Student Simulator` — https://github.com/githubnext/gh-aw-workshop/actions/runs/33830050300
- Run `33827596518` — `Workshop Builder` — https://github.com/githubnext/gh-aw-workshop/actions/runs/33827596518
- Run `33824685848` — `Workshop Author` — https://github.com/githubnext/gh-aw-workshop/actions/runs/33824685848
- Run `33824666280` — `Workshop Builder` — https://github.com/githubnext/gh-aw-workshop/actions/runs/33824666280
- Run `33819608490` — `Workshop Builder` — https://github.com/githubnext/gh-aw-workshop/actions/runs/33819608490

Each of these runs reports `GH_AW_COMPILED_VERSION: v0.82.13` and the check-version step (`check_version_updates.cjs`) fetches `https://raw.githubusercontent.com/github/gh-aw-actions/main/.github/aw/compat.json`, then fails with:

```
##[error]Blocked compile-agentic version: v0.82.13 is in the blocked versions list. Update gh-aw to the latest version and recompile your workflow.
```

Because this occurs in the shared `activation` job before the agent runs, it blocks every workflow in the repository uniformly — this is an infrastructure-level block, not a workflow-specific defect.

### Next Steps

1. **P0 (highest priority)**: Update `gh-aw` in `githubnext/gh-aw-workshop` beyond the blocked `v0.82.13` release and recompile all lock files (`gh aw compile`) so the `GH_AW_COMPILED_VERSION` embedded in each `.lock.yml` reflects an unblocked version.
2. Re-run a sample of the previously failing workflows to confirm the activation step passes.
3. No other buckets were observed in this window; re-scan after the version bump to catch any downstream issues masked by this blocking failure.

Start in githubnext/gh-aw-workshop by locating the agentic workflow lock files and reviewing the activation job's "Check compile-agentic version" step, which uses check_version_updates.cjs. Update gh-aw beyond v0.82.13, run `gh aw compile` to regenerate all `.lock.yml` files, then rerun a sample of the listed workflows and confirm activation succeeds.
