Three TrueHD state-machine fixes from an adversarial audit:
- A corrupt access unit drops forward to the next major sync, but only
the individually-verified corruption now feeds the whole-track poison
verdict; the resync run is collateral. A couple of transient errors can
no longer poison and discard an otherwise-good multi-hour track. The
shared drop tally gains a verified/collateral split for this.
- The per-AU PTS rate is refined only from a CRC-validated major sync, so
a corrupt major sync whose rate nibble decodes to another rate family
can no longer shift the resumed audio — a drop stays a silence gap.
- The resync clears only on a CRC-validated major sync, never on a runt
too short to hold and validate its header.
