retrieve_audio_to decodes whole codec frames but copies only the part inside the requested chunk; the tail of the frame crossing the chunk end (up to 1023 samples for AAC) was consumed by the decoder and lost, so the next chunk started with a hole. On the playback grid (1920 samples at 25fps/48kHz) the hole cycles 128..896 samples and hits 7 of 8 chunk starts -- the heavy stutter/noise heard during playback. Keep the overflow (decode and resampler-flush tails) in a per-session carry buffer and serve it at the start of the next contiguous chunk; clear it on seek, format change and chunk failure. Also make seek() actually drop the cached resampler as its comment claimed. Verified sample-exact: chunked decode of a 440Hz tone now matches a one-shot decode bit for bit, and chunked renders of real media line up with the ffmpeg CLI reference at correlation 1.0 / drift 0. Adds a regression test (playback_sized_chunks_match_oneshot_sample_exact) with a new tone fixture -- demo.mp4's audio is -90dB digital silence and cannot expose the holes -- plus a render_audio_wav example used to diagnose chunk-boundary artifacts offline.

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" |
