Two export killers fixed and the feature surfaced properly: - TicketArena::allocate() reaps finished fire-and-forget slots on every new submit, but RenderTask classified finished tickets by asking the arena for their kind/time afterwards - any ticket that completed before the next submit (all of them on the inline backend) failed with 'Render ticket reported an unexpected timestamp' and the export died after writing a header-only file. RenderTask now records each ticket's delivery key at submit time instead. - File > Export becomes 导出序列 (all 8 locales): the dialog offers a sequence picker (any sequence in the project, the current one preselected) instead of silently exporting the current one, and the project bin's sequence context menu gains 导出序列 opening the same dialog. Engines expose sequence_entries / current_sequence_id / start_export_of. - The export-project dialog drops its dead hand-typed path field (OK already asked the platform save dialog). - New end-to-end test: a one-second sequence exports to a real H.264/AAC MP4 that probes and decodes back to the clip's content.

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" |
