+# Synology Act Runner Split PR Body
+
+## Title
+
+`chore: split Synology act_runner start and re-registration scripts`
+
+## Body
+
+- Added `tools/re_register_act_runner_synology.sh` for explicit host-mode re-registration.
+- Added `tools/start_act_runner_synology.sh` for boot-time daemon start only.
+- Kept `tools/setup_act_runner.sh` as the bootstrap path, but made the re-registration flow explicit and repeatable.
+- Switched the runner registration labels to `self-hosted:host,snapshot-admin-host:host` so the job runs in host mode instead of Docker job containers and can be targeted by a dedicated deployment label.
+- Updated `docs/SYNOLOGY_SNAPSHOT_ADMIN_POC.md` and `docs/ROADMAP_WBS.md` so the operator flow and WBS notes match the new runner split.
+- The `snapshot_admin.yml` workflow is split into push smoke validation and manual full validation, which reduces routine CI cost while preserving the full web smoke path on demand.
+
+## Verification
+
+- `python tools/validate_snapshot_admin_workflow_v1.py`
+- `python -c "import yaml, pathlib; yaml.safe_load(pathlib.Path('.gitea/workflows/snapshot_admin.yml').read_text(encoding='utf-8'))"`

+## 4b. Gitea Actions runner label
+
+Use a unique host label so the deployment job is not mixed with generic self-hosted work.
+
+- Runner label: `snapshot-admin-host`
+- Registration example:
+
+```bash
+REG_TOKEN="<runner-registration-token>" \
+GITEA_URL="http://192.168.123.100:8418" \
+RUNNER_LABEL="snapshot-admin-host" \
+bash tools/re_register_act_runner_synology.sh
+```
+
+- Workflow selector:
+
+```yaml
+runs-on: [self-hosted, snapshot-admin-host]
+```
+
+## 4c. Queue handling
+
+- If the deploy workflow stays queued, it usually means the host runner is busy.
+- Check the job currently holding the runner before re-dispatching.
+- Do not keep dispatching deploy runs back-to-back. The workflow already uses `concurrency` to cancel in-progress duplicates.

+## Queue check
+
+If the deployment workflow stays queued for more than a few minutes:
+
+1. Confirm the runner is registered with the host label.
+   - `RUNNER_LABEL=snapshot-admin-host`
+   - Re-register with `bash tools/re_register_act_runner_synology.sh` after setting the registration token.
+2. Confirm the runner daemon is running.

+4. If another job is occupying the runner, wait for it to finish or cancel the stale workflow from Gitea.
+5. Re-dispatch `snapshot_admin_deploy.yml` after the runner is idle.

 - Loopback `200` confirmed.
