 This confirms the localhost-side service path, auth gate, and `/tables` route work as expected
 in the workspace. It does not replace the NAS-side reverse proxy verification.
 
+## Workflow deploy success evidence

+The Synology deploy workflow was executed against the NAS-hosted `act_runner` and the job-level
+log showed a successful local readiness cycle:
+
+- `healthcheck failed: http://127.0.0.1:8787/api/state`
+- `[deploy] healthcheck retry 1/30`
+- `[deploy] healthcheck retry 2/30`
+- `healthcheck ok: http://127.0.0.1:8787/api/state`
+- `snapshot-admin-web-v6`
+- `[deploy] snapshot admin deploy verification complete`
+- `Job succeeded`

+This is workflow-level success evidence only. It confirms the deploy job can start the service,
+wait for readiness, and pass verification on the NAS runner. It does not by itself satisfy the
+full external reverse-proxy/browser evidence required to close `WBS-7.9`.
