- compose-test-sync: fix 3 failing tests (NOTE_TO_MIDI, DrumLoopAnalyzer mock, section name) - generate-song: CLI wrapper + RPP validator (6 structural checks) + 4 e2e tests - reascript-hybrid: ReaScriptGenerator + command protocol + CLI + 16 unit tests - 110/110 tests passing - Full SDD cycle (propose→spec→design→tasks→apply→verify) for all 3 changes
