Feature screens live in `src/features/` (home, workspace, chords, ranges, player, settings). `src/lib/analysis.ts` and `src/lib/job_runner.ts` call typed Tauri IPC commands, with a browser fallback that serves demo data when not running inside Tauri. -- `apps/desktop/src-tauri/src/main.rs` — the Rust orchestration boundary. 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. - -Data flow: React UI → Tauri IPC command → Rust validation + Python subprocess over stdin/stdout → job status and progress events emitted back to the UI. - -Supporting packages: - -- `packages/shared-types` — the stable TypeScript contracts (rehearsal domain, analysis jobs, confidence, provenance, export summaries) shared by the UI and the orchestration layer. Both sides must use these types instead of inventing parallel schemas; contracts are property-tested with fast-check. -- `packages/shared-config` — shared tsconfig/ESLint bases. -- `scripts/harness/quickcheck.sh` and `scripts/checks/` — fail-fast mechanical gates, including doc presence, plan `Security Notes`, forbidden patterns, and supply-chain/workflow-pinning verification. - -## Key conventions - -- Coverage is a hard gate: the Python engine requires 100% test coverage and 100% docstring coverage (Ruff `D100`–`D107` across `src`, `tests`, and repo scripts). Exported TypeScript declarations in `packages/shared-types` and `apps/desktop/src` require JSDoc with a description; `no-console` is an error. -- Gitflow: `develop` is the default branch; `feature/*` targets `develop`, `main` is the protected release branch. Direct pushes to protected branches are not allowed, and every merge needs the required checks plus a passing CodeRabbit review (see `CONTRIBUTING.md` and `docs/repository/gitflow.md`). -- The PR template (`.github/PULL_REQUEST_TEMPLATE.md`) requires a quickcheck confirmation, `Security Notes` (attack surface, trust boundary, mitigations, test points), a dependency/supply-chain checklist, and i18n impact. -- i18n: the UI ships Korean and English locales (`apps/desktop/src/locales/ko`, `en`). Any user-visible string change must update both. -- Documents under `docs/plans/` must include `Security Notes`; `scripts/checks/verify_security_notes.py` enforces this mechanically. -- Lockfiles (`package-lock.json`, `uv.lock`, `Cargo.lock`) are committed and must stay in sync; GitHub Actions are SHA-pinned. Adding a direct dependency requires the admission rationale defined in `AGENTS.md` and `docs/security/dependency-policy.md`. -- CI beyond quickcheck: `gate / ci / rust-check` (Tauri cargo check on macOS) and `build-baseline` Windows/macOS amd64+arm64 native builds are merge gates, alongside CodeQL, dependency-review, sbom, bandit, trivy, secret-scan, and security-audit workflows. Do not weaken or skip them. -- Version metadata lives in `VERSION`, the root `package.json`, and `CHANGELOG.md`; release flow is tag-driven (see `docs/operations/deploy-runbook.md`). diff --git a/README.md b/README.md index 74312e3e..6ae16c44 100644 --- a/README.md +++ b/README.md @@ -1,6 +1,6 @@ # BandScope -BandScope is a public GitHub project for a local-first desktop app that turns a song into a practical rehearsal view: likely harmony by section and by instrument or vocal role, section roadmap, tempo and groove cues, rough stem previews, playable ranges, simplification hints, transposition or capo guidance, overlap cues, visible confidence, and rehearsal priorities without DAW complexity. +BandScope is a public GitHub project for a local-first desktop app that turns a song into a practical rehearsal view: likely harmony by section and by instrument or vocal role, section roadmap, tempo and groove cues, separated stems, playable ranges, simplification hints, transposition or capo guidance, overlap cues, visible confidence, and rehearsal priorities without DAW complexity.
