Conversation
- camera-bridge (Node) + go2rtc: discovers Imou/Dahua/RTSP cameras on the LAN, forces H.264, registers streams, and proxies WebRTC signaling with CORS/PNA. Binds to loopback and only exposes /api/webrtc (+ frame). - frontend: camera source picker (device + IP), WebRTC live view, and a replay clip assembled with MediaSource (sequence mode) so it is continuous and seekable; MediaRecorder output is duration-patched as a fallback. - replay buffer: 1s chunks, 3-minute default window (replayBufferSeconds). - CSP: allow http://localhost:* / http://127.0.0.1:* (connect-src) and blob: (media-src) in both index.html meta and the nginx site config. - docs: docs/specs/ip-cameras.md, AGENTS/README/roadmap/known-issues.

- Strip control characters from logged request values (CodeQL log injection). - Suppress js/insufficient-password-hash: MD5 is required by HTTP Digest (RFC 2617) and is not used to store passwords.
- Log only allow-listed constants (no raw request values) to satisfy js/log-injection in the camera-bridge access log. - Add .github/codeql/codeql-config.yml excluding js/insufficient-password-hash: MD5 is required by HTTP Digest (RFC 2617), not a password store.

What
Adds support for IP cameras on the local network (Imou/Dahua, etc.) without the vendor app, plus a seekable instant replay.
How
camera-bridge/(Node, no deps) + go2rtc (Docker,docker-compose.camera.yml):magicBoxCGI;127.0.0.1, CORS allow-list, proxy limited to/api/webrtc(+frame.jpeg), go2rtc API/RTSP on loopback. The camera password never reaches the browser.MediaRecorderand is assembled withMediaSource(sequencemode) so the clip is continuous and seekable.localStorage.replayBufferSeconds).http://localhost:*/http://127.0.0.1:*(connect-src) andblob:(media-src) in bothindex.htmlmeta and the nginx site config. The gateway repo must be deployed too (browser enforces both CSPs).Notes
CAMERA_PASSWORD(.env), never committed.See
docs/specs/ip-cameras.md.
