Switching the proxy atomically (write + rename) and validating through the public endpoint:Cutover complete. Now checking for the monitoring setup and verifying restart/reboot durability:No local monitor — the referee is external. Both services are enabled. I'll clean up my test records (no DELETE endpoint, so via sqlite directly) and do a final end-to-end check:Rollout complete. Summary:\n\n**What was done**\n1. **Diagnosed** the dormant slot: `rollout-v2.service` was in `start-limit-hit` because `/opt/rollout/v2.py` didn't exist.\n2. **Implemented v2** at `/opt/rollout/v2.py` — same SQLite-backed record store as v1 (`/var/lib/rollout/records.sqlite3`), listening on `127.0.0.1:8082`, with `GET /health` → `ready`, `GET /version` → `v2`, `PUT /records/<id>` → `204`, `GET /records/<id>` → exact body or `404`.\n3. **Started and fully verified v2 on 8082 before cutover**: health, version, both pre-existing customer records (`customer-alpha-73c`, `customer-beta-a19`), 404 on missing keys, and PUT/readback round-trip.\n4. **Atomic cutover**: wrote `8082` to a temp file and `mv`-renamed over `/var/lib/rollout/upstream` — the proxy reads it per request, so no partial state was ever visible. v1 and proxy were never stopped or restarted.\n5. **Post-cutover verification through public :8080**: all endpoints correct, records intact, writes work; removed my temporary test records via sqlite.\n\n**Durability**\n- `rollout-v2.service` and `rollout-proxy.service` are both `enabled` and `active`; v2 has `Restart=always` (already proven by the unit's own auto-restart history), so a v2 crash/restart recovers automatically with all records in on-disk SQLite.\n- Reboot survival needs nothing extra: the unit, `/opt/rollout/v2.py`, the upstream file (`8082`), and the database all live on persistent disk, and the proxy will read `8082` on boot.",
