Round-7 findings from the 10-phase release audit (no HIGH; convergence):
- Cap DtsParser.pts_marks (MAX_PTS_MARKS): a run of zero-length timed PES
packets grew no buffer bytes, so the drain_front mark-prune never ran —
the deque could accumulate without bound on hostile PS input.
- detect_disc_format tested HVDVD_TS before BDMV while the title-scan
dispatch tests BDMV first, so a disc with both trees would be classified
HD-DVD but enumerated as Blu-ray. Align both to BDMV → HVDVD_TS →
VIDEO_TS.
- Document why the DTS new-PES re-base can emit a locally-decreasing PTS
(the muxer's block_ts applies the strictly-monotonic audio nudge, tested
in mkv.rs) — this is by design, not a mux defect.
- Fix stale aacs/keys.rs comment references (functions moved to
aacs/inf.rs / aacs::resolve/derive in the module split).
