* craft-timeline: a neutral timeline model and the import builder model: a Project of bins and items (media, sequences, subclips, and items no interchange format carries), sequences of tracks with clips, transitions, markers and effects with keyframes. Cut down from FilmCraft's project model to what Final Cut Pro 7 XML, FCPXML and OpenTimelineIO describe; EffectCraft already uses that shape for its interchange. Three things stay the application's: effects (looked up through a Catalog the caller supplies), generators beyond the common ones (Generator::Other with an opaque payload), and per-object extension JSON (ext) that a format can carry unread. fx: the effect and parameter ids the formats name themselves, and Standard, a catalog of just those. build: FilmCraft's import Builder and shared helpers (filmcraft-interchange common.rs at 4bec22bd) on the model, with the effect registry replaced by the catalog, and the bounds every import ends with (Imported::bound, from lib.rs). * craft-timeline: Final Cut Pro 7 XML (xmeml) on the neutral model fcp7: FilmCraft's xmeml reader and writer (filmcraft-interchange fcp7.rs at 4bec22bd) moved onto craft_timeline::model, behind feature xml. - XML is read with craft-xml, strictly: at most 256 levels of nesting (the limit EffectCraft checked with its own depth scan before handing documents over), 2 000 000 nodes, 256 MiB; a document type declaration with an internal subset and entities XML does not define are refused. It is written with craft-xml's Writer. - Effects other than motion, opacity, time remap, audio levels and pan are looked up through the caller's Catalog, by id and by name, and written with the catalog's stable name and category. - An application generator round-trips as <namespace>:<payload> in effectid (FilmCraft wrote filmcraft:<json>); transparent video, counting leader and bars and tone are written by name, which the reader already took. - Finding the sequence a clip item is in is one walk of the document instead of an ancestors() lookup per clip item. tests/it: FilmCraft's FCP7 integration tests (the hand-written Premiere-style document, the rich round trip, the 48-case property round trip, split mono and stereo channels, sub-frame spans, absurd timebases and start timecodes, the link-group bound) on the model, with a test catalog for the four application effects they use. * craft-timeline: FCPXML on the neutral model fcpxml: FilmCraft's FCPXML 1.9-1.11 reader and writer (filmcraft-interchange fcpxml.rs at 4bec22bd) moved onto craft_timeline::model, behind feature xml. XML is read with craft-xml as fcp7 is; filters other than the transform, blend and volume adjustments go through the caller's Catalog by name, and an effect resource's uid is <namespace>.<effect id> (FilmCraft wrote filmcraft.<id>). ExportOptions gains fcpxml_version. tests/it/fcpxml.rs: FilmCraft's FCPXML integration tests on the model (the hand-written connected-clips document, hostile lane numbers, standalone video stills, self-referencing compound media, round trips at 1.9, 1.10 and 1.11, the property round trip with its regression seed, percent-decoded relative URLs). The FCP7 tests export to FCPXML again where FilmCraft's did.
