Two decision docs for the live-HLS timeline work:
- mse-timestamp-offset — native-PTS default for live; timestampOffset reserved
for relocation (the manifest→buffer / encoded layer).
- live-timeline-anchoring — align demuxed tracks and recover turnover via PDT,
not sequence number (the manifest layer).
Resolve open questions [4] (sync anchor) and turnover startTime recovery in
live-presentation-modeling, pointing at the decisions.
