### Future usability work
Dockable editor panels, arrangement multiselection, independent track inserts,
resizable pinned track headers and customizable shortcuts remain future work.
They require separate model/layout designs and acceptance tests.
Arrangement multiselection, independent track inserts and customizable shortcuts
remain future work. Dockable editor panels and resizable pinned track headers
are implemented in Phase 46.

history and plugin editing, but do not constitute a dedicated end-to-end matrix
for all four internal devices. Additional qualification is tracked in Phase 40.
Missing extensions: editable instrument parameters/presets, pitch bend, sample
instruments, click-free/tempo-synced delay, stereo reverb/diffusion, explicit seek
history policy and automatic tail rendering. These are planned in Phases 41–44;
they are not part of the checked initial subset. See
The initial subset lacked editable presets, pitch bend, sample instruments,
smooth/tempo-synced delay, stereo reverb, seek history policy and automatic tails.
These audit gaps are addressed by Phases 41–44 below. See
[BUILTIN_DEVICES.md](BUILTIN_DEVICES.md) for controls and explicit limitations.

Layout and window positions are session-only. The floating transport requires
1220 pixels of width; mixer minimum size is 600 × 420. Other editors cannot be
detached, and general dock layouts are absent. Persistence, compact transport
and additional panels are tracked in Phases 45–46. See
The original subset used session-only positions, a 1220-pixel transport and
only two detachable panels. Phases 45–46 add persisted geometry, a compact
transport and editor panels. Mixer minimum remains 600 × 420. See
[WORKSPACE.md](WORKSPACE.md) for usage and limits.

### Tasks and acceptance criteria
- [ ] Define supported dock locations and layout ownership for sequencer, piano roll and modular graph panels.
- [ ] Detach/dock each supported editor without duplicating project, selection or history state.
- [ ] Support resizable pinned track headers and preserve editing coordinates, scrolling and focus after reparenting.
- [ ] Integrate with Phase 45 layout persistence and provide a safe reset-layout action.
- [ ] Verify minimum/large layouts, cross-panel editing, repeated reparenting and shutdown/error paths.
- [x] Define supported dock locations and layout ownership for sequencer, piano roll and modular graph panels.
- [x] Detach/dock each supported editor without duplicating project, selection or history state.

- [x] Verify minimum/large layouts, cross-panel editing, repeated reparenting and shutdown/error paths.
### Implementation status
Planned. Phase 39 only detaches transport and mixer; broader docking and
resizable pinned headers from Phase 37 remain outstanding. These follow-up
phases cover gaps found in Phases 38–39 and their documented limitations;
unrelated outstanding features in earlier phases retain their existing status.
Implemented: complete Sequencer/Graph panels and Piano Roll reparent between
floating windows and their main tabs, with shared model/history/selection and
preserved scroll positions. Validated preferences persist layouts; reset docks
panels and restores default rectangles. Arrangement headers/selectors stay pinned
and resize from 180 to 360 pixels. Supported docking is explicitly limited to
original tabs; arbitrary split layouts and drag docking are future extensions.
Core/settings, GUI lifecycle/editing/restart and integrated checks are recorded
below. See WORKSPACE.md and PREFERENCES.md.

### Integrated validation for Phases 40–46
Each phase was built and tested before its separate implementation commit.
Core/reliability tests cover devices, migration, persistence, DSP partitions,
transport history and export. GUI tests cover editing, shared state and panel
lifecycle; CLAP/VST2/VST3/LADSPA fixture and live software JACK suites retain the
existing workflows. Sanitizers cover built-in DSP/export and GUI lifetimes;
static analysis and staged installation check the final integrated changes.
Human listening, arbitrary third-party plugins and physical hardware remain
unqualified. Listening WAV generation and manual procedures are documented in
BUILTIN_DEVICES.md. Application project format is now 15, reading versions 1–14.
