+      on finalize + startup, `getOldestPendingJob`, `markInterruptedJobs` now running-only (pending
+      queue survives restart). `startJob` kept as a `enqueueJob(...,'start')` wrapper.
+- [x] 2 REST job API — `POST /jobs` (create script|pipeline, action start/queue), `GET /jobs` (+`?live=1`,
+      now returns mode/exitCode/isLive), `GET /jobs/:id`, `GET /jobs/:id/log?offset=`, `POST /jobs/:id/stop`.
+      Router mounted at `/jobs` and `/pipeline-jobs`. *Needs a restart to deploy; then curl/phone-testable.*
+      WS consolidation still pending (old `/api/tasks/run/ws` + `/api/tasks/pipeline/ws` still live).
