Audit fixes (14 critical, 22 warnings): - UDF: bounds checks on all ICB/FID parsing from disc data - SCSI Linux: saturating_sub on residual, CDB length guard, buffer size guard - SCSI macOS: SCSITaskStatus u32 (was u8 — stack corruption) - AACS: EC mod_inv returns infinity instead of panic, key reduced mod n - AACS: do_handshake tries all host certs (was returning on first failure) - H.264: bounds check on SPS < 4 bytes - ContentReader: error on missing unit key (was zero-fill) - KEYDB: flat redirect loop (was recursive), 100MB response limit, Windows HOME fallback - ISO writer: AVDP extent order, partition length, allocation cap - Network: removed TCP_NODELAY on bulk stream - MKV: guard on u64::MAX seek - disc.rs: saturating_sub on extent offset, simplified dead region code - cargo fmt (610 violations), cargo clippy --fix (55 auto-fixes) DVD support (new files): - src/ifo.rs — IFO parser (VIDEO_TS.IFO, VTS_XX_0.IFO, PGC chains, cells, streams) — 13 tests - src/mux/ps.rs — MPEG-2 Program Stream demuxer (pack headers, PES, private stream 1) — 12 tests - src/mux/codec/mpeg2.rs — MPEG-2 video parser (sequence headers, I-frame detection) — 15 tests - src/css/crack.rs — split-attack algorithm (LFSR cipher needs verification — test ignored) 226 tests total (was 186), 1 ignored (CSS crack needs cipher verification).
