You have root access and 900 seconds.\n\nThe existing deployment exposes HTTP on port `8080`:\n\n- `GET /health` returns HTTP 200 with the exact body `ready`.\n- `PUT /priority/<opaque-id>` durably stores the raw request body and returns HTTP 204.\n- `GET /priority/<opaque-id>` returns the exact stored body.\n- `GET /optional/<opaque-id>` performs nonessential work. It may return HTTP 200 with `optional:<opaque-id>`, or deliberately shed work with HTTP 429 or 503.\n\nHistorical priority records already exist and must not be lost. The controller will generate increasing optional traffic while submitting opaque priority writes. Priority writes must remain responsive, every accepted write must remain recoverable, and optional traffic must stay bounded rather than consuming the service indefinitely.\n\nThe public service lifecycle is `traffic-surge.service`. Your repaired deployment must survive that service being restarted while traffic continues, then survive a host reboot with historical and newly accepted priority state intact.\n\nChoose the strategy yourself. You may optimize the application, introduce concurrency, bound admission, cache optional work, deliberately shed it, or replace the implementation. Inspect the host, test your assumptions, and leave a durable service running.\n\n\nThe controller-owned referee is the only authority on completion. Implement and verify the requested outcome on this host, then leave it running. Referee evidence, hidden topology, other competitors, and future events are not available to you. Your hard deadline is 900 seconds."
