Now verify it directly against the contract, including that it serves the existing records from the shared DB.v2 serves all existing records correctly. Let me verify PUT round-trip on v2 with a test record, then confirm the public endpoint is currently on v1 before cutover.v2 fully functional. Public endpoint is on v1. Now the atomic cutover: write `8082` to a temp file and `rename` over the upstream file (atomic on same fs).Public endpoint is now serving v2 with all records preserved. Now verify durability: restart v2 service and confirm everything survives, then confirm services are enabled for reboot.Rollout complete. Summary:\n\n**What was done**\n- Implemented `/opt/rollout/v2.py` — a stateful record service on `127.0.0.1:8082` mirroring v1's SQLite-backed behavior (same `/var/lib/rollout/records.sqlite3`), with `/health`→`ready`, `/version`→`v2`, and `PUT/GET /records/<id>` per contract.\n- Started `rollout-v2.service` (reset its failed state, started, confirmed `active`).\n- Verified v2 directly: health, version, all existing records (`alpha-original`, `beta-original`), 404 for missing, and a PUT round-trip — all correct.\n- Performed atomic cutover by writing `8082` to `upstream.tmp` and `mv`-ing it over `/var/lib/rollout/upstream` (atomic rename on same filesystem). The proxy reads this file per request, so no request ever saw a partial/missing upstream — both v1 (8081) and v2 (8082) stayed running throughout.\n- Verified the public endpoint (`:8080`) immediately served `v2`, `ready`, and all records intact.\n- Did **not** stop or restart `rollout-proxy.service` or `rollout-v1.service` during cutover.\n\n**Durability verified**\n- `systemctl restart rollout-v2.service` → recovered, public endpoint stayed healthy, all records intact.\n- All three services (`rollout-proxy`, `rollout-v1`, `rollout-v2`) are `enabled`, so they come back after a full host reboot. `rollout-v2.service` has `Restart=always`.\n- Records persisted in the SQLite file; v2 reads the same DB, so existing customer state is preserved across restart/reboot.\n\n**Final state**\n- Proxy (`:8080`) → upstream `8082` (v2), running and enabled.\n- v2 (`:8082`) running, enabled, `Restart=always`.\n- v1 (`:8081`) still running (untouched, as required) and enabled.\n- All records present and correct.",
