Speed matters, but only a durable, fenced topology can win.   The controller-owned referee is the only authority on completion. Do not stop after merely describing the work. Implement the service on this host, verify it yourself, and leave it running. You have no access to referee evidence or other competitors.  # Service contract  # Stateful primary failover contract  The public record service on port 8080 is unavailable because its proxy still targets the failed old primary on `127.0.0.1:8081`. A healthy read-only replica is running on `127.0.0.1:8082`. Existing customer state is stored in `/var/lib/failover/records.sqlite3` and must not be discarded or replaced.  Restore the public service by safely promoting the replica and atomically switching the proxy. The replica reads its role from `/var/lib/failover/replica.role` on every request. It accepts writes only when that file contains `primary`. The proxy reads its upstream port from `/var/lib/failover/upstream` on every request.  The public API contract is:  - `GET /health`: `200` with exact body `ready`; - `GET /role`: `200` with exact body `primary` after promotion; - `PUT /records/<id>`: persist the UTF-8 body and return `204`; - `GET /records/<id>`: return the exact body, or `404` when absent.  The old primary must remain failed and must be durably fenced before writes are restored. Preserve `/var/lib/failover/primary.failed`, create `/var/lib/failover/primary.fenced`, and do not make port 8081 listen again. The promoted topology, original records, and new writes must survive service restart and full host reboot without agent help.   The referee performs host reboot testing. Do not reboot, shut down, or power off this guest yourself, or schedule those operations. Leave the deployment running for the referee to test. --permission-mode bypass --output-format json --transcript /var/tmp/agents-of-empires-deepseek/transcript.json\n",
