 - [Native shared-encode sender](./research/native-shared-encode-sender.md): consolidated Draft #16/#18/#22/#23/#25/#28 ladder, unclassified product-gate failure, staged revalidation, and stop line.
 - [Native H.264 hardware decision](./research/native-h264-hardware-decision.md): bounded WebCodecs no-go, proved Media Foundation/NVIDIA hardware encode, the default-fmtp `42c01f` stop, and the retained interop boundary.
 - [Native H.264 opt-in path](./research/native-h264-opt-in-path.md): explicit H.264 sender mode, exact Pion profile registration, and one bounded Host/Viewer loopback with hardware caveats.
-- [Realtime quality adaptation](./research/realtime-quality-adaptation.md): fixed Browser VP8/no-video-hint evidence, manual quality ceilings, diagnostic-only capture/send/receive correlation, and LiveKit-owned SFU dual-representation adaptation evidence.
+- [Realtime quality adaptation](./research/realtime-quality-adaptation.md): Browser codec and `motion` evidence, manual quality ceilings, path-quality authority, and LiveKit-owned SFU representation adaptation.
+- [Cross-restart room recovery](./research/cross-restart-room-recovery.md): pending lineage, authority-epoch, invitation-replay, and bounded media-rebuild evidence without reopening durable room storage.
 - [Browser background capture diagnostics](./research/browser-background-capture.md): browser lifecycle evidence, a privacy-bounded capture/send/receive experiment, interpretation gates, and non-goal keepalive mechanisms.
 - [Browser screen-audio quality](./research/browser-screen-audio-quality.md): capture/source compatibility, live sender-ceiling readback, Opus negotiation boundaries, and remaining audible/device evidence.
 - [Display name and presence boundaries](./research/display-name-presence.md): browser-local storage failure behavior, Unicode normalization, control-character policy, and the Web-only presence capability boundary.
