* Progress docs to the craftrules standard; full re-measure against Pro Tools 2026.4.1
Stage: alpha. Menu breadth 482/512 (94.1%, measured), feature breadth ~70%,
ready for real work ~40%; ~350-570 agent-hours to beta, ~950-1,450 to full parity,
calibrated on this repo's PR history.
- ROADMAP.md rewritten: stage banner, two numbers, dimension/feature/language tables
- docs/target-app-parity.md: authoritative assessment (area table moved from ROADMAP)
- docs/gaps.md: 22 ranked gaps with evidence and estimates
- docs/roadmap.md: milestones, current focus, beta plan
- docs/ui-, file-format-, hardware-, plugin-, localization-parity.md: new checklists
- docs/parity.md -> docs/parity-checklist.md (generated by cargo xtask parity)
- architecture.md: video, vst3-host, au-host crates; device I/O limits

* Stage: pre-alpha under the core-workflow gate
Add the alpha gate to docs/roadmap.md: interface recording at a chosen buffer
size, MIDI recording, and session interchange with Pro Tools fail, so the stage
moves from alpha to pre-alpha (~5 points and ~110-180 agent-hours to alpha).
Mark the alpha blockers in docs/gaps.md; update ROADMAP.md, target-app-parity.md
and README.

* Add mainstream-practitioner and essentials-user readiness numbers
Mainstream practitioner ~36% (weekly-area depth 50.6% x 0.90 interaction x 0.92
stability x 0.85 file exchange) and essentials user ~57% (core-feature depth
72.4% x 0.90 launch/stability x 0.90 discoverability x 0.97 files), with written
weights, discounts and GitHub user evidence. Full ready-for-real-work checked
against its written dimension weights (40.6%); unchanged at ~40%, stage unchanged.

* Readiness by audience: hours to ~95% for full, mainstream and essentials
Full ~40% / 950-1,450 h, mainstream ~36% / 380-600 h, essentials ~57% / 110-200 h,
calibrated on this repo's PR history. The full number is already an additive
weighted sum over the written dimension table; method unchanged.

Video (new standalone crate soundcraft-video):
- Pure-Rust H.264 (Baseline/Main/High), ProRes (all flavours) and Motion JPEG decoding with
ISO-BMFF demux, adapted from FilmCraft's crates; fuzzed with mutated/truncated movies
- TrackKind::Video with ClipContent::Video referencing Session.videos; file.import_video adds
the picture track and the movie's audio; relinking on open; video.offset/online/list
- Video and Video Universe windows, thumbnails on the timeline, background decoding
Third-party plugins:
- Plugin state (CLAP state ext, VST3 component + controller state) saved in sessions
- Hosted instances created, state-loaded and dropped on the UI thread, never the audio thread
- Plugin editors: floating CLAP GUIs and VST3 views on macOS (verified with Melodyne)
- New isolated FFI crate soundcraft-au-host: Audio Units on macOS (effects and instruments,
parameters, latency, MIDI, ClassInfo state), wired into the mixer and plugin browser
UI: Window > Renderer (speaker layout with live levels and object positions), Window > UI
Customization (interface scale, reduce motion), Window > Configurations > Auto-Update.
Fix: saturating sample-index math in clip rendering (hostile stretch values overflowed).

Surround:
- main and bus formats up to 9.1.6 and Ambisonics; pairwise constant-power
surround panner (divergence, centre, LFE, height) per track and send;
ITU fold-down; multichannel bounce with correct WAV channel masks;
multichannel device output; surround panner and multichannel meters in the
Mix window; setup.main_format, mix.surround_pan, mix.send_surround_pan
VST3:
- soundcraft-vst3-host: isolated unsafe crate (vst3 bindings, MIT), scans
standard folders, hosts components/processors/controllers, params,
latency, notes; VST3 menu; engine.vst3_plugins; e2e tests with a fixture
Hardening:
- positions from parameters clamped; offline renders capped and bounded to
track material; loop/transport limits; hostile-parameter property test

- soundcraft-clap-host: scans standard CLAP folders, loads plugins via
clap-sys/libloading, implements the Plugin trait (audio, params, latency,
notes); the only crate allowed unsafe, every block documented; stubs on wasm
- mixer, engine (mix.insert, engine.clap_plugins) and Mix window CLAP menu
- end-to-end tests against a Rust-built fixture plugin
- file.bounce_stems: one soloed file per track

Workspace for SoundCraft, a clean-room pure-Rust Pro Tools-class DAW:
timebases and tempo maps, WAV/AIFF/FLAC/symphonia audio IO with peaks,
SMF and MIDI ops, 26 original DSP plugins, the session model, the mix
engine, ~180 registered commands with undo, a cpal player, and the
agent rules (AGENTS.md, ATTRIBUTION.md).
