 ### Added
 
-- Name tonight's first playable range on the ready rehearsal map and tell the player to check that span on their instrument before the section.
 - Display the analyzed song tempo (BPM) as a badge in the rehearsal workspace.
 - 각 합주 역할(Role)별 개인 연습 진행도를 0~100% 범위로 기록 및 시각화할 수 있는 연습 진척도(`practiceProgress`) 트래커 기능 추가. UI 컨트롤(슬라이더 및 +/- 버튼)과 한/영 다국어 지원 포함.
 
-### Changed
-
-- Pinned npm `10.9.9` as the approved lockfile generator, activated it through Node-bundled Corepack before dependency consumption, and fail closed unless its bundled `tar` is at least `7.5.19`; primary CI still consumes the committed lock only through frozen `npm ci` validation, rejects mutable npm resolution in the lock gate, requires integrity evidence for public-registry lock entries, and preserves generator-sensitive root `@esbuild/*` peer metadata.

-### Fixed
+### 성능 최적화 (Performance)
 
-- Upgraded the local score PDF parser to `pdfjs-dist` 6.2.108, pinned Undici 7.29.0 across the workspace, and constrained PDF loading to copied in-memory bytes with a same-origin bundled worker and npm-generated lock provenance.

Tauri commands (`start_analysis_job`, `get_analysis_job_status`, `select_local_audio_source`, `import_youtube_url`) validate untrusted input (project IDs, file paths, URLs) and spawn the Python engine as a subprocess. There is no loopback HTTP listener and no network path for local analysis.
 - `services/analysis-engine` — Python package `bandscope_analysis` (librosa/numpy). Entry point `cli.py` reads a JSON job request on stdin and prints a structured job-status JSON envelope on stdout (`--progress-jsonl` streams progress lines). `api.py` orchestrates the pipeline across the `separation`, `sections`, `roles`, `chords`, `ranges`, `temporal`, `transcription`, and `youtube` modules.
