[aw-maintenance:failures-investigator] Failure Report: gh-aw workshop repo — blocked compile-agentic version blocking all activations

- **Target repository**: `githubnext/gh-aw-workshop`
- **Window**: last 24 hours (from 2026-09-03T03:46:12Z)
- **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 | Workshop Builder, Workshop Student Simulator, Workshop Author (and likely other workflows in the 44 failed runs) | `##[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.` | 44 (5 examined in detail; all 5 share this exact signature) | new issue |

### Resolved Buckets

none

Evidence

All 5 examined failures fail at the same job/step (`activation` / `Check compile-agentic version`) with the identical error:

```
2026-09-04T02:56:10.5158098Z ##[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.
```

Representative runs:
- Workshop Builder: https://github.com/githubnext/gh-aw-workshop/actions/runs/33831291288
- Workshop Student Simulator: https://github.com/githubnext/gh-aw-workshop/actions/runs/33830050300
- Workshop Builder: https://github.com/githubnext/gh-aw-workshop/actions/runs/33827596518
- Workshop Author: https://github.com/githubnext/gh-aw-workshop/actions/runs/33824685848
- Workshop Builder: https://github.com/githubnext/gh-aw-workshop/actions/runs/33824666280

The compiled workflows all embed `GH_AW_COMPILED_VERSION: v0.82.13`, which is now on the gh-aw-actions `compat.json` blocked-versions list, so the `activation` job fails before the agent ever starts (no logs from the agent itself — pure infrastructure gate failure). Since this check runs identically in every compiled `.lock.yml`, it plausibly explains all 44 failed runs across the 24h window, not just the 5 examined in detail.

### Next Steps

1. Upgrade the `gh-aw` CLI/action pin in `githubnext/gh-aw-workshop` past v0.82.13 (to the current unblocked release).
2. Recompile all `.github/workflows/*.md` sources with the updated `gh-aw` so the embedded `GH_AW_COMPILED_VERSION` in each `.lock.yml` is no longer on the blocked list.
3. Re-run a sample of the previously failing workflows to confirm the `activation` / `Check compile-agentic version` step now passes.

In githubnext/gh-aw-workshop, inspect the gh-aw CLI/action pin and the workflow sources under .github/workflows/*.md, then compare their compiled .lock.yml files. Recompile the workflows so GH_AW_COMPILED_VERSION is no longer v0.82.13, and rerun a sample to confirm the activation / Check compile-agentic version step passes.
