+## Phase 37 — Workspace Navigation and Direct Editing
+
+### Goal
+Reduce menu hunting and make the workspace useful for everyday project editing
+with a direct transport, track inspector and searchable commands.
+
+### Tasks and acceptance criteria
+- [x] Add Ctrl+P command search with filtering, keyboard navigation, Enter and Escape.
+- [x] Expose active menu actions through existing callbacks, without duplicating command implementations.
+- [x] Make project BPM editable from the transport with validation, undo and failed-preparation rollback.
+- [x] Replace the passive sidebar with a context-aware gain/pan/mute/solo inspector.
+- [x] Preserve unfinished numeric input across timer refreshes and avoid no-op history edits.
+- [x] Add a session summary, Fit song and optional Follow playhead navigation.
+- [x] Persist Follow playhead through the existing Preferences / Apply workflow.
+- [x] Test command selection/cancellation, inspector edits, tempo rollback/undo and navigation.
+- [x] Refresh all screenshots, including a command-palette view, and document the workflow.
+
+### Implementation status
+Implemented over the existing C model, history and backend APIs, with no new
+dependencies or project format change. Tempo edits stop and rewind transport;
+track/clip and piano selections survive. Fit song uses the supported 24..384
+pixels-per-beat zoom levels; very long projects still require scrolling.
+The inspector targets the selected mixer channel in Mixer and the arrangement
+track in other views. Command search lists active menu actions; it is not a
+plugin scanner or a key-binding editor. See WORKSPACE.md.
+
+### 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.
+

+
+## Phase 38 — Internal instruments and effects
+
+- [x] Add always-available Soft Keys and Sub Bass MIDI instrument presets.
+- [x] Add Delay and Reverb with bounded controls and effect automation.
+- [x] Integrate track selection, graph wire insertion, undo and saved projects.
+- [x] Preserve older projects; reserve format 13 internal device identities.
+- [x] Verify DSP tails, block partition consistency, note release/panic and persistence.
+- [x] Refresh application screenshots and add internal device editor views.
+
+See [BUILTIN_DEVICES.md](BUILTIN_DEVICES.md) for controls and explicit limitations.

 ## Recommended Execution Order
 
 Reorder the phases when the audit reveals a blocking dependency. Do not mark a phase complete merely because code exists: its acceptance criteria must be demonstrated by builds, tests, or documented manual verification.
