Test gaps (guarded code was untested):
- disc: cover is_complete_feature_presentation's CHAPTER_SPAN_MIN_FRAC (0.5)
boundary — clustered marks (span < 0.5*dur) are not a feature; marks at the
0.5 threshold are. Adds bd_title_chaptered_span helper (issue #45).
- hevc: exercise the length-prefix self-check WIRING in HevcParser::parse
end-to-end — a desynced access unit is dropped, a well-formed one emitted.
Adds a test-only FORCE_FRAMING_DESYNC seam (frame_data is length-prefixed by
construction, so no real input desyncs it) (issue #52).
- labels: cover resolve_feature_hint's winner_hint early-return — a non-empty
winner_hint wins over the Tier-2 bdj_feature menu-walk result (issue #46).
Doc drift:
- keysource.md: resolve_unit_keys + UnitKeyResolution (matched/miss_path/
matched_entry/store_entries de-conflation).
- aacs-trace.md: MatchedEntry, KeyStep.matched_entry/store_entries, and the
KeyNode::NoDerivableKey node.
- hevc.md: add the "length-prefix self-check (issue #52)" section the hevc.rs
comment points to.
Craft:
- labels: hoist the duplicated MIN_FEATURE_SECS (60) from fox.rs and
paramount.rs to a single shared const in labels/mod.rs.
