{"agent":"codex","input":"Error rates for our Navidrome-based Go service rose between 20:15 and 21:00 UTC today. Use the Grafana connection to read that window: in Prometheus, http_request_count by endpoint, client and status, http_request_latency by endpoint, and media_scans and media_scan_last by success; in Loki, the service's error and warning lines. List any alerts that fired. Compare the window with the commits to scanner/ and server/subsonic/ in the last 7 days and read the diff of each one that touches a failing endpoint, a scan phase or auth_limiter.go. You may run `go test -tags netgo,sqlite_fts5` on a package to check a hypothesis. Write incident.md with a summary, a UTC timeline, the most likely cause with commit and file, evidence for each claim (PromQL, LogQL or command and its result), causes ruled out, and every query you ran. Change no code and nothing in Grafana.","connections":["grafana"],"resources":[{"url":"https://github.com/your-org/your-app"}]}
