Parse releases with an explicit fixed positional model and document the
whole logic in British English doc-blocks.
Model:
- [0]=Artist, [1]=Title are fixed and never matched against dictionaries,
so titles like "Split"/"Demo"/"De" are never eaten.
- [len-1]=Group is always read from the line, not from the query key.
- [len-2]=Year when it is a 4-digit 19xx|20xx token; otherwise the slot is
resolved as a middle-zone token (e.g. FLAC still picked up as format).
- The middle zone is resolved via case-insensitive dictionaries in the order
format -> source -> bit-depth -> resolution -> edition -> language ->
catalogue number. Position within the zone is irrelevant.
Catalogue numbers:
- Any "(...)" token in the middle zone is a catalogue number regardless of
content (digits, roman numerals, dots, underscores, mixed case). Removed
the hasDigit requirement and character whitelist that rejected real
catalogues like (DYN.3140-2) and (GOWP_DCCCLXXXIX).
- Splitting never breaks tokens inside parentheses.
Case handling: lookups are case-insensitive; stored values keep their
original case from the line.
Documentation: replaced Ukrainian comments in parser.go and analyzer.go with
British-English doc-blocks describing the model, tail resolution order,
catalogue rule and confidence scoring.
Tests:
- Add TestParseCatalogNumberWithDotAndRoman for (DYN.3140-2)/(GOWP_DCCCLXXXIX).
- Update case-insensitive, split-title, no-year and language expectations.
- go build, go vet and go test all pass.
