The two BlockCore length setters swapped their anchors relative to the C++ semantics they document, so the ported edit commands produced wrong geometry on the live UI paths: roll edits kept the seam still, slides left negative in-points, and trims wrote the timeline in-point into media_in (playing the wrong media content). Adopt three stored-range primitives in block.rs: - set_length_and_media_out: in fixed, out moves, media untouched (resize, trim-out, gaps growing rightward). - set_length_and_media_in: in fixed, out moves, media_in += old-new (resize-with-media-in, splice right half, ripple trim-in). - set_length_keeping_out (new): out fixed, in moves, media_in += old-new (trim-in body and out-neighbour, slide out-neighbour, ripple trim-in of the trailing block). Point every command at the primitive matching its intent (undopointer, undogeneral, undoripple, undosplit, graphops, cli, nodeops) and fix the two real defects the swap hid: - TrackReplaceBlockWithGapCommand grew a following gap rightward, swallowing whatever followed it: the "dragging one clip moves unrelated clips" regression. The gap now grows leftward over the removed block's span; regression test in domain_test. - The ripple/splice trims now advance media_in instead of rewriting it, and BlockSplitCommand writes both halves' ranges and media explicitly (the second half continues from the split point). Rewrite the KNOWN-SWAP expectations to the correct geometry (roll moves the seam, slide has no negative in-point, insert-gaps grows rightward, resize-with-media-in yields media_in = 20) and add the missing media assertions. TrackSlideCommand documents that the caller positions the sliding blocks (the stored model has no track layout).

Roadmap
| Version | Theme | Core Deliverables | Boundary Notes |
|---|---|---|---|
| 0.3 | Plugin Architecture Milestone | Production-ready OpenFX host support | Not about quantity of plugins, but "any OFX plugin loads without crashing" |
| 0.4 | Color, Audio & Performance | .cube/.3dl support, scopes (waveform/vectorscope/histogram), three-way color wheels, waveform auto-sync, BWF timecode sync, audio meters (LUFS/VU), proxy media workflow, hardware-accelerated export (NVENC/VideoToolbox), batch render queue |
Combines the previous 0.4-0.6 scope into one usability milestone: color workflow, audio sync, and 4K/8K performance |
| 0.5 | Animation, Tracking & Collaboration | Bézier keyframe curve editor, basic point tracking, image stabilizer, full multicam angle switching, OpenTimelineIO, EDL/XML import/export | Combines the previous 0.7-0.8 scope into one timeline/interchange milestone |
| 0.6 | Stability Milestone | Project file format freeze (backward compatibility promise), crash recovery, autosave, memory optimization | "Feature freeze" testing period before 1.0 |
| 1.0 | Production Ready | Complete documentation, installers, known issues list, community support channels | Declared "ready for serious projects" |
