expvar counters for connections, rooms, games, submissions by rejection reason, eliminations, chat, joins and bot moves, served on a separate debug address so they never sit on the public mux, plus one structured word_rejected log line per refused word carrying the normalized word and its link. GET /readyz flips to 503 while draining; SIGTERM stops new rooms, waits up to NOITU_DRAIN_TIMEOUT for live games, then shuts down. GET /version and the startup log carry the build's git describe. Fuzz targets for the frame decoder, the text sanitizer and Vietnamese normalization; the last one found that composing before lowercasing could leave a non-NFC result, now recomposed after lowering. CI runs on dev as well as main, gates gofmt and golangci-lint, tracks the buf major instead of an exact pin, and dependabot watches every ecosystem. The lint findings that had been hidden by the default per-issue cap are fixed.
