Things to check:\n1. systemd units: failover-proxy.service, failover-replica.service. Check whether they're enabled (persistent across reboots).\n2. Whether something is trying to restart the old primary on 8081 (e.g., a failover-primary.service that keeps restarting). \"do not make port 8081 listen again\" — need to check whether there's a unit or timer for the primary. Also, \"durably fenced\" might mean that a fencing mechanism exists — for example, a service that tries to launch the primary and checks primary.fenced, or something like that. Let's look at the systemd units.\n\nPlan:\n1. Check systemd units (systemctl list-units | grep failover, cat the unit files).\n2. Check the contents of the sqlite DB (make sure records exist).\n3. Fence the old primary: verify that nothing is listening on 8081, and if there's a primary unit, disable/mask it. Create `/var/lib/failover/primary.fenced` (persistent, e.g., write + sync). Preserve primary.failed.\n4. Promote the replica: atomically write `primary` to `/var/lib/failover/replica.role` (temp file + mv + sync).\n5. Switch the proxy: atomically write `8082` to `/var/lib/failover/upstream`.\n6. Verify the API via port 8080: /health, /role, PUT/GET of records, confirm that the original records are intact.\n7. Confirm reboot persistence: services are enabled. Role/upstream files persist across reboots. Check that there's no boot-time mechanism that resets them (e.g., an ExecStartPre that writes `replica` to replica.role or `8081` to upstream). Must read the unit files carefully.\n8. Also, \"durably fenced\": maybe the replica/proxy scripts check primary.fenced? From what I've read of the code — they don't. There might be a third unit \"failover-primary\" that checks the fenced file before starting. Let's confirm.\n\nAlso, check whether the services are enabled (symlinks in multi-user.target.wants). This is a NixOS system (nix store paths), so probably a NixOS configuration. systemctl should work.\n\nLet's start investigating.\n\nThe overall picture is clear: the proxy (8080) reads `/var/lib/failover/upstream` (currently `8081` → stopped) and forwards to it, and the replica (8082) reads `/var/lib/failover/replica.role` (currently `replica` → read-only). Next, let's check the systemd units and see whether something might restart the old primary or reset these files at boot time.\n",

Create `/var/lib/failover/primary.fenced`. Never listen on 8081 again.\n\nBoth are managed by systemd (processes launched from /nix/store paths — probably NixOS systemd units). Things to check:\n1. systemd units: failover-proxy.service, failover-replica.service. Check whether they're enabled (persistent across reboots).\n2. Whether something is trying to restart the old primary on 8081 (e.g., a failover-primary.service that keeps restarting). \"do not make port 8081 listen again\" — need to check whether there's a unit or timer for the primary. Also, \"durably fenced\" might mean that a fencing mechanism exists — for example, a service that tries to launch the primary and checks primary.fenced, or something like that. Let's look at the systemd units.\n\nPlan:\n1. Check systemd units (systemctl list-units | grep failover, cat the unit files).\n2. Check the contents of the sqlite DB (make sure records exist).\n3. Fence the old primary: verify that nothing is listening on 8081, and if there's a primary unit, disable/mask it. Create `/var/lib/failover/primary.fenced` (persistent, e.g., write + sync). Preserve primary.failed.\n4. Promote the replica: atomically write `primary` to `/var/lib/failover/replica.role` (temp file + mv + sync).\n5. Switch the proxy: atomically write `8082` to `/var/lib/failover/upstream`.\n6. Verify the API via port 8080: /health, /role, PUT/GET of records, confirm that the original records are intact.\n7. Confirm reboot persistence: services are enabled. Role/upstream files persist across reboots. Check that there's no boot-time mechanism that resets them (e.g., an ExecStartPre that writes `replica` to replica.role or `8081` to upstream). Must read the unit files carefully.\n8. Also, \"durably fenced\": maybe the replica/proxy scripts check primary.fenced? From what I've read of the code — they don't. There might be a third unit \"failover-primary\" that checks the fenced file before starting. Let's confirm.\n\nAlso, check whether the services are enabled (symlinks in multi-user.target.wants). This is a NixOS system (nix store paths), so probably a NixOS configuration. systemctl should work.\n\nLet's start investigating.\n\nThe overall picture is clear: the proxy (8080) reads `/var/lib/failover/upstream` (currently `8081` → stopped) and forwards to it, and the replica (8082) reads `/var/lib/failover/replica.role` (currently `replica` → read-only). Next, let's check the systemd units and see whether something might restart the old primary or reset these files at boot time.\n",

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. --permission-mode bypass --output-format json --transcript /var/tmp/agents-of-empires-qwen/transcript.json\n",
