Decompose the live media-playlist reload into two single-responsibility behaviors, matching the content-snapshot ([1]) vs refetch-policy ([3]) category split in live-presentation-modeling.md: - resolve-track (loader, [1]) now also services live reloads: it watches a per-type reload-epoch slot and re-fetches when it advances (gate: load if unresolved OR epoch > last serviced), carries the prior snapshot's timeline forward, and sets presentation.streamType. ConcurrentRunner id-dedup + recording the epoch at schedule time gives drop-if-busy coalescing. - schedule-track-reload (scheduler, [3]) is what remains of reload-track once the fetching is removed: it bumps the reload epoch on a target-duration cadence (half on unchanged), inert for VoD via #EXT-X-ENDLIST, and enters on track *selection* so its bumps also drive first-resolve retries. reload-track is removed; the live-hls and live-playlist-spike engines compose resolve* + schedule* in its place. Also fix updateMediaSourceDuration for live: it only wrote Infinity when the MediaSource was already open at entry and returned without scheduling a wait otherwise. The presentation can resolve to Infinity before setupMediaSource opens the MediaSource, so the eager write was missed and the first append pinned a finite live-edge duration — stalling once the window slid past it. Now it defers to sourceopen when not yet open. Verified live playback end-to-end (real-time, Infinity duration, seeked to edge) against a Mux LL-HLS stream.
