 | UT-213 | The direct-play negotiation, one test per branch, against `PlaybackInfo` fixtures whose shapes were all observed on a live server: a supported source direct-plays; a remuxable one direct-streams and reports itself as *not* transcoding; an unsupported codec transcodes; undecodable audio overrides the server's direct-play offer (silent picture is worse than a transcode); a pinned audio track forces a transcode; a ceiling below the source bitrate transcodes even though the codec is fine, and the ladder agrees that rung constrains it; direct play wins over direct stream when both are offered. Plus the ceiling: a per-playback override governs the stream being opened without disturbing the durable default the Settings screen shows, and dropping it returns to that default | DR-225, DR-227 | Done |
 | UT-214 | The loader comes from the transport, never the URL. hls.js is attached for `hls` when available and the element's own loader when not; progressive and local files load directly; the element's `src` is emptied only when hls.js drives it. The two cases that fail against a substring check, and the reason the field exists: a `progressive` stream whose URL contains `.m3u8` is *not* given an HLS loader, and an `hls` stream whose URL contains no `.m3u8` *is*. Both failed against the pre-DR-225 implementation before the fix landed | DR-224 | Done |
 | UT-215 | Waiting for the repository rather than racing it: it resolves immediately when the session is already restored, resolves when the session arrives later (the race the player page lost on mount), still rejects when there genuinely is no session, unsubscribes once settled so a later store change cannot re-settle it, and leaves no armed timer to reject an already-resolved promise | DR-013 | Done |
+| UT-216 | The native-video opt-in is read from one place and only explicit truthy values enable it: absent, empty, `0`, `no`, `false` and anything unrecognised all mean off, because a half-set variable that half-enabled the renderer would configure mpv for video with nothing drawing it — audio over a black rectangle | DR-231 | Done |
