Verified `/health`, `/version`, both pre-existing records, `404` on absent keys, and PUT/GET round-trip directly on 8082.\n3. **Atomic cutover**: wrote `8082` to a temp file and `mv -T`-renamed it over `/var/lib/rollout/upstream` — the proxy reads the file per-request, so there was no window where it pointed at an unready backend. Neither the proxy nor v1 was touched.\n4. **Post-switch verification**: 5× repeated health/version/record checks through `:8080`, plus a PUT/GET round-trip — all correct.\n5. **Durability**: restarted `rollout-v2.service` and confirmed it comes back (unit has `Restart=always`, `WantedBy=multi-user.target`, enabled — survives reboot) with all records intact. Removed my smoke-test record.\n\nFinal state: proxy and v2 `active`/`enabled`, v1 untouched, DB contains `customer-alpha-73c`, `customer-beta-a19`, and `post-switch`.",

Now let's do the atomic cutover of the upstream file, with a tight monitoring loop around it to confirm zero downtime.Atomic rename via `mv` on the same filesystem, and the monitor shows 200 for every request throughout — no outage.

Now confirm v1/proxy are untouched (not restarted) and check service states and enablement.v1 and proxy were never restarted since the initial boot — cutover was seamless. Now verify persistence across a v2 restart and confirm the record file/service will survive reboot.Records and service survive a v2 restart. Everything is enabled for boot persistence (`/opt/rollout/v2.py` is a plain file on disk, `/etc/systemd/system/rollout-v2.service` is enabled, and the sqlite DB is on persistent storage), so it will also survive a full reboot without agent help.\n\n**Summary:**\n- Implemented `/opt/rollout/v2.py`: same sqlite-backed records store as v1 (shared DB at `/var/lib/rollout/records.sqlite3`, preserving all existing records), reporting `v2` on `/version`, listening on `127.0.0.1:8082`.\n- Started `rollout-v2.service` (was crash-looping due to missing file) and verified `/health`, `/version`, and all pre-existing records matched v1 exactly before cutover.\n- Atomically switched `/var/lib/rollout/upstream` from `8081` to `8082` via `mv` (same-filesystem rename) while running a 200ms-resolution monitor against the public port 8080 — every single request returned `200` throughout, confirming zero-downtime cutover.\n- Confirmed via `systemctl show` that `rollout-v1.service` and `rollout-proxy.service` were never restarted or stopped during the whole process.\n- Verified end-to-end through the public endpoint post-cutover: version=`v2`, health=`ready`, both pre-existing records intact, and a new write/read round-trips correctly.\n- Restarted `rollout-v2.service` and confirmed records and health survive it; all three services remain `enabled` for reboot persistence.",

        "terminal_detail": "The setup is clear: v1 and the proxy both share the same sqlite DB, so v2 just needs to run the same record logic on 8082 with `/version` → `v2`. Writing v2 now:Cutover clean. Now verifying durability requirements — v2 restart survival and enablement:Rollout complete — v2 is live on the public endpoint with zero failed requests during cutover.\n\n**What was done:**\n1. **Wrote `/opt/rollout/v2.py`** — same record logic as v1 against the shared `/var/lib/rollout/records.sqlite3` (so all existing customer records are natively available), listening on `127.0.0.1:8082`, with `/version` → `v2`.\n2. **Started the dormant slot**: `systemctl reset-failed rollout-v2.service` (it had hit start-limit while the file was missing) + `start`. Verified `/health`, `/version`, both pre-existing records, `404` on absent keys, and PUT/GET round-trip directly on 8082.\n3. **Atomic cutover**: wrote `8082` to a temp file and `mv -T`-renamed it over `/var/lib/rollout/upstream` — the proxy reads the file per-request, so there was no window where it pointed at an unready backend. Neither the proxy nor v1 was touched.\n4. **Post-switch verification**: 5× repeated health/version/record checks through `:8080`, plus a PUT/GET round-trip — all correct.\n5. **Durability**: restarted `rollout-v2.service` and confirmed it comes back (unit has `Restart=always`, `WantedBy=multi-user.target`, enabled — survives reboot) with all records intact. Removed my smoke-test record.\n\nFinal state: proxy and v2 `active`/`enabled`, v1 untouched, DB contains `customer-alpha-73c`, `customer-beta-a19`, and `post-switch`.",
