[aw-maintenance:failures-investigator] Failure Report: gh-aw-workshop (24h)

- **Target repository**: `githubnext/gh-aw-workshop`
- **Window**: last 24 hours (from 2026-09-02T22:41:42Z)
- **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 (activation job) | `Blocked compile-agentic version: v0.82.13 is in the blocked versions list` | 43 | new issue |

### Resolved Buckets

none

Evidence

All 5 sampled failures (spanning 3 distinct workflows: Workshop Builder, Workflow Skills Editor, Workshop Link Checker) fail in the `activation` job at the `Check compile-agentic version` step with the identical error:

```
##[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:
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33810480125 (Workshop Builder)
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33807856135 (Workflow Skills Editor)
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33807178518 (Workshop Link Checker)
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33805019420 (Workshop Builder)
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33799237747 (Workshop Builder)

All lock files were compiled with `GH_AW_COMPILED_VERSION: v0.82.13`, which is now on the upstream `compat.json` blocked-versions list (fetched from `https://raw.githubusercontent.com/github/gh-aw-actions/main/.github/aw/compat.json`). This is a version-gate failure at the activation stage, not a task-level agent bug, and it affects every workflow whose lock file was compiled with the blocked version — evidence points to a single systemic cause rather than 22 independent defects. The remaining 38 failed run IDs in the window were not individually fetched but occur across the same time span and are very likely the same activation-gate failure repeating on schedule/dispatch triggers.

### Next Steps

1. Update the `gh-aw` / `gh aw` CLI extension used by `githubnext/gh-aw-workshop` to a version newer than the blocked `v0.82.13`.
2. Recompile all `.github/workflows/*.md` sources with `gh aw compile` so the `.lock.yml` files embed a non-blocked `GH_AW_COMPILED_VERSION`.
3. Commit the regenerated lock files and re-run the affected workflows to confirm activation succeeds.

Start by checking the gh-aw CLI extension version and the compiled version in the affected .github/workflows/*.md and .lock.yml files. Run `gh aw compile` after updating the extension, commit the regenerated lock files, and re-run the affected workflows to confirm activation succeeds without the blocked-version error.
