[aw-maintenance:failures-investigator] Failure report: githubnext/gh-aw-workshop — 24h window

- **Target repository**: `githubnext/gh-aw-workshop`
- **Window**: last 24 hours (from 2026-09-03T01:13:44Z)
- **Failed agentic runs**: 43
- **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 (compiled with `compiler_version: v0.82.13`) | `Blocked compile-agentic version: v0.82.13 is in the blocked versions list. Update gh-aw to the latest version and recompile your workflow.` | 43 | new issue |

### Resolved Buckets

none

Evidence

All 43 failed run IDs in the window fail at the `activation` job, `Check compile-agentic version` step, with the identical error message:

```
##[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.
```

The check step runs `check_version_updates.cjs` against `https://raw.githubusercontent.com/github/gh-aw-actions/main/.github/aw/compat.json`, an upstream-controlled block list. Since `v0.82.13` was added to that block list, **every** agentic workflow run compiled at that version fails during activation before the agent job can even start — a total outage for this repository's agentic automation.

No open `[aw-maintenance:failures-investigator]` tracking issues existed prior to this run.

### Next Steps

1. Recompile all workflows in `githubnext/gh-aw-workshop` with a non-blocked `gh-aw` release (later than v0.82.13) using `gh aw compile`, and commit the regenerated `.lock.yml` files.
2. Update the pinned `github/gh-aw-actions/setup`/`setup-cli` refs used by the lock files to the new version.
3. Verify a subsequent scheduled/dispatched run passes the "Check compile-agentic version" step before considering this resolved.

Start with the affected workflow .lock.yml files in githubnext/gh-aw-workshop and the `gh-aw-metadata` headers showing compiler_version v0.82.13. Run `gh aw compile` with a non-blocked release, update the pinned setup/setup-cli references, and commit the regenerated lock files. Verify a scheduled or dispatched run passes the “Check compile-agentic version” step.
