MattJackson fbdfccdd83 Add keys() to IOStream trait — streams know their own decrypt keys 
- IOStream::keys() default returns DecryptKeys::None
- IsoStream and DiscStream override with real AACS/CSS keys
- Pipeline calls input.keys() instead of separate scan_keys()
- Streams are self-contained: read bytes + provide keys

MattJackson 2f52188f77 Drive recovery, reset on open, simplified DiscStream 
- SgIoTransport::reset() — open/close/TUR/escalate on every open
- Drive::read() — single read method with error recovery (min speed,
  sleep 30s, retry, phase 1/2/3 escalation)
- Removed read_timeout, read_sectors, read_range — one read() method
- DiscStream simplified — no on_error/on_success/Recovery, delegates
  all error handling to Drive::read()
- IsoStream no longer decrypts — streams return raw bytes, pipeline
  handles decryption
- reset() on all platforms (Linux real, Windows/macOS stubs)
- Watchdog thread removed — kernel handles USB timeouts

MattJackson 3b96976a7a Add decrypt module, merge to one drive.read(), Disc::decrypt_keys() 
- New decrypt.rs: DecryptKeys enum (AACS/CSS/None) + decrypt_sectors()
- Single drive.read() replaces read_disc/read_content (same SCSI READ(10))
- ContentReader and DiscStream use decrypt_sectors() (no duplicated crypto)
- Disc::decrypt_keys() exposes resolved keys for disc-to-ISO

MattJackson 077e4d018f Bump to 0.8.1, make profile module public, fix unused import 2026-04-13 00:17:57 +00:00
MattJackson f8b5a1eaf1 API: Drive object, typed StreamUrl, tray lock/unlock, Send traits 
- Rename DriveSession → Drive across entire codebase
- find_drives() returns Vec<Drive>, find_drive() returns Option<Drive>
- resolve_device() now pub(crate) — internal only
- StreamUrl is now a typed enum (Disc, Mkv, M2ts, Iso, Network, Stdio, Null)
  with scheme() and path_str() accessors, replacing struct of Strings
- Add lock_tray() / unlock_tray() for safe disc access during rips
- Improve reset() with eject cycle that clears LibreDrive stuck state
- Add Send bounds to ScsiTransport and PlatformDriver traits
- DiscOptions uses PathBuf instead of String for device/keydb paths
- Update doc example to use new Drive API

MattJackson 75f15cae62 Audit v3 fixes: all 3 tiers (19 findings) 
Tier 1 (compilation + correctness):
- Fix nightly-only is_multiple_of → % 2 != 0 (stable Rust compat)
- Fix parse_sample_rate: check 192 before 96 (was returning wrong rate)
- macOS drive discovery: split unix.rs → linux.rs + macos.rs
- Linux: EACCES returns DevicePermission not DeviceNotFound
- CLI pipe.rs: Ctrl+C signal handler added

Tier 2 (correctness + security):
- MkvStream: reset demuxer after scanning→streaming transition
- Windows SPTI: zero data buffer before ioctl
- AACS cert verification: documented why silently skipped
- KEYDB: HOME + USERPROFILE fallback for Windows
- Library modules: pub(crate) for internal modules
- AACS: explicit re-exports, AES primitives pub(crate)

Tier 3 (performance + polish):
- IsoStream: batch 64-sector reads (was 1 sector at a time)
- DiscStream: buffer swap instead of copy in decrypt_and_buffer
- Vec capacity hints in TS/PS demuxer hot paths
- NetworkStream: TLS warning documented
- Batch rip: per-title progress display
- cargo fmt: 0 violations

319 tests, 0 fmt violations.

MattJackson e25035fe8c Fix audit v2 criticals: DiscStream read loop, CSS crack, ISO writer 
Critical fixes:
- DiscStream: persistent read state (was creating new ContentReader per call)
  Full error recovery, AACS/CSS decryption, extent tracking across reads
- CSS crack: labeled 'outer continue (was targeting wrong loop)
- CSS crack: LFSR0 polynomial fixed to match cipher (shifts 8,1,3,7)
- CSS lfsr: operator precedence clarified in LFSR0 init

Warning fixes:
- ISO writer: UDF tag checksums computed (was zeros)
- DVD extents: saturating_add for overflow safety
- Removed dead fields: HandshakeResult.error, ContentReader.content_format
- Added TODO for ISO long_ad >4GB support

319 tests, 20 clippy warnings remaining.

MattJackson ffa0eaba4d cargo fmt + clippy --fix: 104 format violations fixed, 8 clippy auto-fixes 2026-04-11 19:10:20 +00:00
MattJackson 96a65de3ff Chapters, DVD subtitle palette, MKV track flags, progress total_bytes 
Chapters:
- MPLS PlayList marks parsed (mark_type 1 = chapter)
- Chapter struct on DiscTitle (time_secs, name)
- MKV Chapters element with EditionEntry/ChapterAtom per mark
- 3 MPLS mark tests + 2 MKV chapter tests

DVD subtitle palette:
- IFO palette extraction (PGC offset 0xA4, 16 × YCbCr colors)
- YCbCr→RGB conversion for VobSub .idx format
- DvdSubParser codec_private returns formatted palette
- codec_data field on SubtitleStream flows through pipeline
- 5 palette tests (YCbCr conversion, formatting, overflow)

MKV track flags:
- FlagDefault: primary video/audio = 1, secondary = 0
- FlagForced: forced subtitles = 1
- Language: set from stream language code
- Already implemented, verified with 4 new tests

Progress total_bytes:
- IOStream trait: total_bytes() -> Option<u64>
- DiscStream, IsoStream: from disc_title.size_bytes
- M2tsStream, MkvStream: from file metadata on open
- NetworkStream, StdioStream, NullStream: None

316 tests total, all passing.

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

- 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/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 8c2f3898b8 Add IOStream trait and stream-based I/O architecture 
Introduce IOStream trait for uniform read/write across disc, file,
network, and null streams. Rename Title→DiscTitle, add stream URL
resolver, split old stream.rs into focused modules (m2ts, mkvstream,
network, disc, null, resolve, meta).
