Facts read from one compressed audio frame: how many samples it decodes styx:parser (dec-0117 §6: S3/S4 apply — untrusted media bytes). to (packet durations when the container declares none) and the AC-3 / E-AC-3 configuration an ISOBMFF sample entry needs (dac3 / dec3, which Matroska does not store: it only exists in the bitstream).

Every reader takes untrusted bytes and returns null when they do not parse; nothing here panics or indexes out of bounds.
