MattJackson ff5547363b Audit fixes + DVD support foundation (IFO, PS demux, MPEG-2, CSS crack) 
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).

MattJackson 074f21ba58 Refactor error types: replace generic AacsError/DiscError with typed variants 
- Split AacsError { detail } into 13 specific error variants (AacsCertShort,
  AacsAgidAlloc, AacsCertRejected, etc.) with unique error codes E7001-E7012
- Split DiscError { detail } into 7 specific variants (DiscRead, MplsParse,
  ClpiParse, UdfNotFound, DiscNoTitles, DiscTitleRange, DiscNoExtents)
- Add WriteError (E5001), KeydbLoad (E8005), MuxLookahead (E9000), MuxWrite (E9001)
- Add OpenDisc API for single-call open+scan+rip workflow
- Remove all English text from error Display impl (code-only output)
- Normalize doc comments to use -- instead of em dash for ASCII consistency

MattJackson 262f9a7f8d Add keydb updater, update README with labels + multi-lingual + real output 2026-04-07 21:21:18 -07:00
MattJackson d0c5c7fb97 Named constants, error codes, SCSI opcodes, flow documentation 
- Error codes as public constants (E_DEVICE_NOT_FOUND etc.) — single source of truth
- SCSI opcodes as named constants (SCSI_READ_10, SCSI_REPORT_KEY, etc.)
- AACS key class constant, MKB format constant
- No magic numbers in CDB construction
- docs/disc-to-rip.md — end-to-end flow from disc insert to decrypted content
- Links all module docs together as a starting point

MattJackson 985d00f0a4 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.

MattJackson 7db4606038 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.

MattJackson cbf510e70e 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.
