+
+## Implementation Details
+
+**Implementation Files Modified:**
+- `BitwigApiFacade.java` - Added methods `getProjectParameters()` and `getSelectedTrackInfo()` with support for project parameters via MasterTrack and cursor track details
+- `StatusTool.java` - Updated to include project parameters and selected track information in status response
+- `docs/api-reference.md` - Updated to reflect new status response fields including project_parameters array and selected_track object
+- `StatusToolTest.java` - Enhanced unit tests to cover new functionality with both populated and empty scenarios
+
+**Implementation Notes:**
+- Project parameters are accessed via `MasterTrack.createCursorRemoteControlsPage(8)` based on Bitwig's OSC API patterns
+- Selected track information includes index, name, type, and all state flags (muted, soloed, armed, is_group)
+- Only existing project parameters (where `exists()` is true) are returned in the response
+- Selected track returns `null` if no track is currently selected
+- All new fields are properly documented in the API reference with examples
+- Code follows Java conventions and operational guidelines
+- No new external dependencies were added
+- StatusTool tests pass with comprehensive coverage of new functionality
+
+**Testing & Verification:**
+- Unit tests created in `StatusToolTest.java` with comprehensive coverage of new fields
+- Tests cover both scenarios: with data present and with empty/null responses
+- All StatusTool tests pass successfully
+- Integration tests would be covered by broader MCP integration tests
+- Manual testing pending (task 6)
+
+**Documentation Updates:**
+- `docs/api-reference.md` updated with detailed descriptions of new response fields
+- Story file updated with implementation notes and completion status
+

+
+**Summary:** The `StatusTool.java` has been updated to include project parameters and selected track information. The `BitwigApiFacade.java` provides new methods for accessing this data. The `api-reference.md` has been updated accordingly. Unit tests have been created and pass successfully. Manual testing is the only remaining task.
+
+**Items Requiring User Attention:** Manual testing (task 6) needs to be performed before marking the story as complete.
