Speed matters, but only a durable, fenced topology can win.\n\n\nThe 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.\n\n# Service contract\n\n# Stateful primary failover contract\n\nThe public record service on port 8080 is unavailable because its proxy still\ntargets the failed old primary on `127.0.0.1:8081`. A healthy read-only replica\nis running on `127.0.0.1:8082`. Existing customer state is stored in\n`/var/lib/failover/records.sqlite3` and must not be discarded or replaced.\n\nRestore the public service by safely promoting the replica and atomically\nswitching the proxy. The replica reads its role from\n`/var/lib/failover/replica.role` on every request. It accepts writes only when\nthat file contains `primary`. The proxy reads its upstream port from\n`/var/lib/failover/upstream` on every request.\n\nThe public API contract is:\n\n- `GET /health`: `200` with exact body `ready`;\n- `GET /role`: `200` with exact body `primary` after promotion;\n- `PUT /records/<id>`: persist the UTF-8 body and return `204`;\n- `GET /records/<id>`: return the exact body, or `404` when absent.\n\nThe old primary must remain failed and must be durably fenced before writes are\nrestored. Preserve `/var/lib/failover/primary.failed`, create\n`/var/lib/failover/primary.fenced`, and do not make port 8081 listen again.\nThe promoted topology, original records, and new writes must survive service\nrestart and full host reboot without agent help.\n\n\nThe 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."
