This audit treats the codebase as the source of truth: CMakeLists.txt, Source/*, frontend/src/App.tsx, frontend/src/store/useDAWStore.ts, store action modules, frontend/src/store/actionRegistry.ts, and mounted React panels/modals.
Features are sorted by impact first, then complexity.

Implemented But Partial / Caveated These have real code surfaces, but should not be counted as fully delivered DAW features yet.
Feature
Status
Polyphonic pitch correction / solo-note resynthesis
Detection and MIDI extraction exist; PolyResynthesizer is still stub-like
AAF import
Stubbed in session interchange
LTC output
Bridge stub exists, not a real implementation
Live capture start/stop
Bridge stubs exist
Media Explorer audio preview
UI exists; backend preview function appears to only acknowledge/log
AI continuation workflow
Present in workflow list but marked unavailable
Drum editor / media pool
Store toggles/actions exist, but no mounted full UI components were found
Master FX reorder
Track/input reorder exists; master reorder is noted as unsupported in UI
Legacy executeScript/loadScriptFile bridge names
Stubbed, but newer runScript/runScriptCode paths are implemented
