AACS complete: Unit_Key_RO.inf parser, disc hash, MKB processing, resolve chain
...
- Unit_Key_RO.inf: proper parser matching libaacs format (uk_pos, stride,
AACS1 48-byte / AACS2 64-byte key spacing, title→CPS unit mapping)
- Disc hash: SHA1 of Unit_Key_RO.inf for KEYDB lookup
- MKB processing: processing keys + subdiff records + cvalues → media key
(verify media key record with 12-byte zero check)
- Content Certificate parser: detect AACS version + bus encryption flag
- resolve_keys(): full 3-path chain:
1. disc hash → KEYDB → VUK (fast, 99% of discs)
2. KEYDB media key + VID → VUK
3. MKB + processing keys → media key → VUK
- setup_aacs() now reads Unit_Key_RO.inf + Content Cert from disc via UDF
- 31 tests passing

AACS 2.0 full pipeline: handshake, bus key, decrypt, transparent API
...
- aacs.rs: content decryption (AES-CBC aligned units, bus decrypt, VUK
derivation, unit key decrypt). 11 tests including synthetic roundtrip.
- aacs_handshake.rs: SCSI authentication (ECDH on AACS 160-bit curve,
ECDSA sign/verify, AES-CMAC, bus key derivation, read_data_key).
14 tests including EC order, ECDH shared secret, cert verification.
- disc.rs: transparent API — Disc::scan() detects AACS, authenticates,
derives keys internally. ContentReader decrypts on the fly. App never
sees AACS details.
- error.rs: AacsError (E7000) variant
BF v12 complete: 284 unique matches from 8 AWS instances.

Add AACS module: KEYDB.cfg parser, VUK lookup, 180K disc entries in <2s
...
Parses device keys, processing keys, host cert, per-disc VUKs.
Full KEYDB.cfg (60MB, 180K entries) parsed in 1.85 seconds.
All test discs found with VUKs.
Next: disc hash computation, title key decryption, content decryption.

Reduce read_disc timeout to 5s (was 30s)
...
Prevents indefinite hangs on encrypted/unreadable sectors.
Some discs put MPLS/CLPI/JAR data in AACS-encrypted regions
that block reads without proper AACS authentication.

Always unlock on DriveSession::open()
...
Silently ignores unlock failures (unencrypted discs).
Fixes disc-info on discs that gate reads behind AACS auth.

Add JAR parser: extract audio/subtitle labels from BD-J menus
...
Scans BDMV/JAR/*.jar class files for track label patterns:
eng_MLP_ → TrueHD, eng_ADES_US_ → Descriptive Audio (US)
dan_PGStream4 → Danish subtitles
Solves the "3x AC-3 English" problem — we identify Descriptive Audio, commentary, compatibility tracks.
Future: set MKV "visual impaired" flag automatically during mux.
Local only — needs more disc samples to validate before publishing.

UDF: file data on physical partition, disc API with typed streams

Library disc API: Disc, Title, Stream with typed codec/hdr/color
...
Clean public API for disc scanning. CLI should only display,
never parse binary formats directly.
Disc::scan() → titles → streams with:
codec (Hevc/TrueHd/Ac3/Pgs/etc), pid, language,
resolution, frame_rate, channels, hdr, color_space,
secondary flag, label

Add disc format parsers: UDF, MPLS, CLPI
...
- udf.rs: read files from Blu-ray disc filesystem
- mpls.rs: parse playlists → titles with clips and timestamps
- clpi.rs: parse clip info → EP map with coarse/fine SPN entries
- disc.rs: high-level title scanning, sector extent mapping
- drive.rs: add read_disc() for unencrypted reads, scsi_execute()
- error.rs: add E6000 DiscError
Stage 1 of freemkv rip: identify titles and their sector ranges.

Platform-agnostic SCSI transport with cfg gates
...
- scsi::open() returns Box<dyn ScsiTransport> on any platform
- Linux SG_IO behind #[cfg(target_os = "linux")]
- macOS IOKit and Windows SPTI stubs with TODO
- drive.rs uses scsi::open() — no platform-specific imports
- Compiles on macOS (returns "platform not yet supported")

Refactor: Chipset architecture, remove supported/status gatekeeping
...
- PlatformType → Chipset enum (MediaTek, Renesas)
- unlock_mode + unlock_buf_id stored in profile, not derived from enum
- Removed ReadinessStatus, supported field, needs_flash — library is agnostic
- Removed DriveMatch/Flashable — if we have a profile, try unlock
- profiles.json: chipset + unlock_mode + unlock_buf_id, no program/supported
- mt1959.rs reads mode/buf_id from profile fields directly
- Tests: find_known_drive, find_unknown_drive

Structured error codes: E1000-E5000, no user-facing text in library
...
Error codes:
1000-1001: device errors (not found, permission)
2000-2002: profile errors (unsupported, not found, parse)
3000-3003: unlock errors (failed, signature, not unlocked, not calibrated)
4000-4001: SCSI errors (command failed, timeout)
5000: I/O errors
All errors carry structured data (vendor_id, opcode, etc).
Applications format their own user-facing messages.
Library returns code + data, never English text.
