Replaces 'first-match-wins by array order' with 'highest-confidence-
wins, array order tiebreaker'. Removes the arbitrariness when more
than one parser can claim a disc (e.g. one with both
bluray_project.bin and playlists.xml).
New types in labels::mod:
pub enum Confidence { Medium, High }
pub struct ParseResult { labels: Vec<StreamLabel>, confidence }
ParseResult::high(labels) / ::medium(labels) constructors
Parser signature change: every parse() now returns
Option<ParseResult> instead of Option<Vec<StreamLabel>>. Updated all
six parsers in lockstep:
paramount: High (fully structured XML)
criterion: High (fully structured XML)
pixelogic: High by default, Medium when an unknown token component
is encountered (the skip-unknown path now propagates the
coverage gap to the caller instead of silently degrading)
ctrm: High (structured key-value)
dbp: High (anchor scan with vocab routing)
deluxe: still returns None pending Phase D — signature aligned
Registry behavior:
extract() iterates all detect-positive parsers, picks highest
Confidence with non-empty labels. Equal confidence falls to array
order (deterministic). Same selection logic in analyze().
LabelAnalysis grew a confidence: Option<Confidence> field so the
diagnostic surface (freemkv-tools labels-analyze) exposes which
confidence tier the selected parser claimed. labels-analyze JSON
and labels-corpus-check structural diff both gained the field.
Precommit (cargo +1.86 fmt + clippy + test) green.
Closes the platform unification: every label parser now routes
purpose/qualifier/codec classification through one source of truth
(vocab.rs) instead of N hand-rolls, and every binary-blob byte
scanner goes through one helper (text::extract_ascii_strings).
pixelogic.rs:
- Drop local extract_strings (~20 lines) — use text::extract_ascii_strings.
- HARDENING: replace with skip-unknown-component +
trace log. Pre-refactor behavior: any single uncatalogued token part
(e.g. a future codec ID, new framework variant) silently dropped the
entire stream record. New behavior: skip just the unknown part,
surface what we know about the stream.
- 8 new unit tests cover basic audio/subtitle paths, commentary,
descriptive, region variant, the new skip-unknown-component
regression, and the non-audio/non-subtitle early-out.
ctrm.rs:
- Replace with
vocab::purpose(&name). Now word-boundary matched — 'Commenter Pro
Track' no longer false-matches Commentary.
- Replace with vocab::qualifier(&name).
Same word-boundary tightening, plus picks up Forced and
DescriptiveService for free.
- Preserved structural commentary signal via
as a fallback when name is silent (e.g. 'audio_commentary_1.name=Track 2').
- 6 new unit tests including the 'Commenter' false-positive regression
and the SDH-only-on-subtitles boundary.
text.rs:
- Drop module-level dead_code allow now that pixelogic uses
extract_ascii_strings.
Net: all 5 framework parsers now on the unified platform. Future work
(deluxe Phase D, paramount/criterion XML hardening) builds on the
same scaffolding.
Precommit green.
- SectorReader trait decouples disc scanning from SCSI
- Disc::scan_image() for ISO and any sector source
- resolve_encryption() handles AACS 1.0/2.0/none in one path
- IsoStream: full UDF/MPLS/CLPI/labels pipeline from ISO files
- StdioStream: stdin/stdout pipe
- Strict scheme:// URL format with validation
- Labels module refactored to SectorReader
- 7 stream types total
Architecture:
- Each BD-J format in own file: paramount.rs, criterion.rs, pixelogic.rs, ctrm.rs
- Standard interface: detect() → bool, parse() → Option<Vec<StreamLabel>>
- PARSERS array in mod.rs — drop in a new parser with one line
- Shared vocab.rs for BD spec codec names only (MLP→TrueHD, AC3→Dolby Digital)
- All other label data passes through raw from disc — no guessing
Changes:
- New: paramount.rs (playlists.xml — Paramount/onQ format)
- Renamed: bluray_project.rs → pixelogic.rs
- Renamed: stream_properties.rs → criterion.rs
- Merged: language_streams.rs + menu_base.rs → ctrm.rs
- Removed: jar module (superseded by labels), dead apply functions
- Added: DriveSession::eject() with PREVENT ALLOW MEDIUM REMOVAL
- Added: DiscRegion enum (Free/BluRay/Dvd)
- Fixed: capture sector ranges now include all files (only skip STREAM/)
- Renamed: StreamLabel.region → variant (not a BD spec field)
