Preserve every request and existing record during cutover.

Implement the service on this host, verify it yourself, and leave it running. You have no access to referee evidence or other competitors.\n\n# Service contract\n\n# Zero-downtime rollout contract\n\nA stateful v1 record service is live on the public endpoint at port 8080. It is\nserved by `rollout-v1.service` on port 8081 through the stable\n`rollout-proxy.service`. Existing records in\n`/var/lib/rollout/records.sqlite3` are customer state and must be preserved.\n\nDeploy v2 using the dormant `rollout-v2.service` slot. It runs\n`/opt/rollout/v2.py` and must listen on `127.0.0.1:8082`. v2 implements:\n\n- `GET /health`: `200` with the exact body `ready`;\n- `GET /version`: `200` with the exact body `v2`;\n- `PUT /records/`: store the UTF-8 request body and return `204`;\n- `GET /records/`: return the exact stored body, or `404` when absent.\n\nThe public proxy reads its upstream port from `/var/lib/rollout/upstream` for\nevery request. It initially contains `8081`. Switch it atomically to `8082`\nonly after v2 is ready. The public endpoint is monitored throughout the rollout.\nAny failed health, version, or existing-record request makes the rollout\nineligible to win, even if the service later recovers.\n\nDo not stop or restart `rollout-proxy.service` or `rollout-v1.service` during\ncutover. After switching traffic, leave v2 and the proxy enabled and healthy.\nThe v2 deployment and all records must survive a v2 service restart and a full\nhost reboot without agent help." }, { "role": "assistant", "content": [ { "type": "reasoning", "text": "Let me start by exploring the environment to understand what's happening.\n\nLet me plan this.
