The main-process sample showed the UI thread spending 100% of its time in TicketArena::wait from the painted frame's synchronous render: every cache-missed playhead frame sync-rendered inline, and the seek-priority ticket then stole worker capacity from the pre-render window while the blocked tick loop could not feed it — a self-reinforcing loop that made playback unusably choppy. On a playback miss the viewer now shows the last displayed frame while the pre-render window warms up/catches up (paused monitors and the very first frame keep the synchronous path). Adds a gpui test driving real playback that requires the window to supply playhead frames, and the real-footage bench_playback example used for the measurements (152 fps aggregate on 1080p H.264 at 480p preview, decode-bound).

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" |
