+            ## Org-runner routing: a queued job is almost never an agent problem
+            
+            A job that shows `labels: ["<your-label>"]`, `status: queued`, `runner_name: ""`
+            while the runner reads `online` + `busy: false` is a ROUTING failure, not a
+            runner failure — the runner has nothing to execute. Work the causes in order:
+            
+            1. **The runner group does not allow public repos (the silent one).** An org
+               runner in a group whose `allows_public_repositories` is `false` is INVISIBLE
+               to every public repo in the org, so their jobs queue forever with no error
+               anywhere. Check and fix with a REAL boolean (the `-f` flag sends the string
+               `"true"`, which the API rejects as `"true" is not a boolean` — use `--input`):
+            
+               ```bash
+               gh api /orgs/<org>/actions/runner-groups --jq '.runner_groups[]|{id,name,allows_public_repositories,visibility}'
+               echo '{"allows_public_repositories": true}' > rg.json
+               gh api -X PATCH /orgs/<org>/actions/runner-groups/<id> --input rg.json
+               ```
+            
+            2. **`labels` mismatch.** The runner must carry every label `runs-on` names.
+               Compare `gh api /orgs/<org>/actions/runners --jq '.runners[0].labels'` against
+               the job's `labels` (a reusable workflow may resolve a `vars.` label you forgot
+               to set, e.g. `vars.REVIEW_RUNNER_LABEL`).
+            
+            3. **A stale broker session.** After a container restart the listener can log
+               `A session for this runner already exists` / `TaskAgentSessionConflictException`
+               and retry on a 30s loop without taking jobs, while still reporting `online`.
+               A full clean cycle clears it — `charly remove` (deregisters) then
+               `charly config` + `charly start` — not just a restart.
+            
+            Confirm the fix by watching the job, not the runner: a picked-up job flips to
+            `in_progress` with `runner_name` set, and the workflow's steps then appear.
+
+            ## `gh` must be present for a review/gate runner
+
+            A runner whose job is to execute `gh`-driven workflows (the org `pr-validator`
+            runs `gh api` / `gh pr comment` / `gh pr merge`) needs the `gh` CLI in its
+            image — compose `/charly-tools:gh` (it is not part of the base toolchain). A
+            runner without it fails the workflow at its first `gh` call.
+
