Test-hardening release, no runtime changes. Adds spec-grounded unit tests
across the silent-corruption surfaces — UDF/MPLS/CLPI/IFO parsing, BD/DVD
title + extent assembly, AACS/CSS key handling, TS/PS demux + codec parsers,
MKV/EBML container output, the mux pipeline, sector prefetch + decrypt
decorator, drive/SCSI sense decoding, label extraction, and core I/O. Each
test is grounded in the format spec or real on-disc behavior and verified to
fail under a targeted source mutation. No behavior changed.
Library-wide review-and-fix pass: tightened AACS keydb/handshake/variant
handling and trailing-partial-unit policy, corrected MPLS mark offset and
added UDF allocation bounds, hardened the mux/codec framing and M2TS paths,
guarded SCSI READ CAPACITY short transfers and unified error mapping, added
overflow guards on untrusted disc input, and made prefetch shutdown
deterministic. Release profile now builds with thin LTO + single codegen unit.
- DriveSession::open() no longer requires profile match — works on any optical drive
- init()/probe_disc() return error gracefully for unknown drives
- find_drives() returns all optical drives (PDT 0x05), not just profile-matched
- has_profile() check for callers
- AACS 2.0: handshake wired into resolve_aacs() — real VID + read_data_key
- DriveId: added raw_gc_010c field for GET_CONFIG 010C response bytes
Features:
- Open drive identification via SPC-4 INQUIRY + MMC-6 GET CONFIGURATION
- 141 supported drives with bundled profiles
- MT1959 platform: unlock, calibrate, raw sector reads
- DriveSpeed enum: BD1x-BD12x, DVD1x-DVD16x
- Field names follow SPC-4 §6.4.2 and MMC-6 §5.3.10 standards
- No proprietary fingerprints — open matching by SCSI fields
- Zero config: profiles compiled into binary
Tested on real hardware: HL-DT-ST BD-RE BU40N 1.03
