# CODEGRAPH

## Project

- Product: Wails v3 / Go desktop dictation app.
- Git root: `/Users/ar/Projects/PrivateVoice2/03-O`.
- Source root: `/Users/ar/Projects/PrivateVoice2/03-O/C1.source/privatevoice.src`.
- Current branch purpose: Round 6 Cantonese language version real-user test package based on `v2.2.0-build20260702.0303`.
- Protected behavior: existing macOS App Store, local DMG, Monterey compatibility, Windows preview, model download safety, and paste/clipboard protection must not be changed without a scoped task and QA plan.

## Core Entrypoints

- `C1.source/privatevoice.src/main.go`: process startup, data migration, logger, single-instance guard.
- `C1.source/privatevoice.src/app.go`: Wails app wiring, settings window, tray, recorder, hotkey loop, ASR init, paste orchestration.
- `C1.source/privatevoice.src/embed.go`: embeds frontend assets and app/tray icons.

## Language And Model Registry

- `C1.source/privatevoice.src/internal/model/profile.go`: model and language IDs, model profile shape, install status types.
- `C1.source/privatevoice.src/internal/model/registry.go`: language profile order, model profiles, language profiles, and normalization.
- `C1.source/privatevoice.src/internal/modelselection/selection.go`: resolves current language and model, including manual-model fallback.
- Round 6 Cantonese path:
  - Language ID: `yue-HK`, displayed as `粤语`.
  - Default model: `sensevoice-yue-2025-09-09`.
  - Backend: SenseVoice with `LanguageParam="yue"`.
  - The Cantonese language profile intentionally has no upgrade models, so Qwen3-ASR and X-ASR are not shown as Cantonese-specific options.

## Platform Modules

- Audio: `C1.source/privatevoice.src/internal/audio/recorder.go`
- Hotkey:
  - macOS: `C1.source/privatevoice.src/internal/hotkey/hotkey_darwin.go`
  - Windows: `C1.source/privatevoice.src/internal/hotkey/hotkey_windows.go`
- Text input:
  - macOS: `C1.source/privatevoice.src/internal/input/paste_darwin.go`
  - Windows: `C1.source/privatevoice.src/internal/input/paste_windows.go`
- ASR engine:
  - macOS: `C1.source/privatevoice.src/internal/engine/engine_darwin.go`
  - Windows: `C1.source/privatevoice.src/internal/engine/engine_windows.go`
  - Linux: `C1.source/privatevoice.src/internal/engine/engine_linux.go`
- Overlay:
  - macOS: `C1.source/privatevoice.src/internal/overlay/overlay_darwin.go`
  - Windows: `C1.source/privatevoice.src/internal/overlay/overlay_windows.go`

## Windows Preview Scope

- Windows preview supports `SenseVoice` only.
- Non-SenseVoice models remain visible in settings but are disabled through `model.IsModelSupportedInCurrentBuild`.
- Windows unsupported reason: `windows_preview_unsupported`.
- Windows overlay remains native Win32/GDI+, with a larger translucent spectrum-style capsule indicator for recording states.
- Build script: `C1.source/privatevoice.src/scripts/build-windows-preview.sh`.
- Evidence verifier: `C1.source/privatevoice.src/scripts/verify-windows-qa-evidence.sh`.

## macOS Package Scope

- Local DMG script: `C1.source/privatevoice.src/scripts/build-local-macos.sh`.
- Universal DMG script: `C1.source/privatevoice.src/scripts/build-local-macos-universal.sh`.
- Monterey compatibility script: `C1.source/privatevoice.src/scripts/build-local-macos-monterey.sh`.
- Developer ID / notarization script: `C1.source/privatevoice.src/scripts/build-release-macos.sh`.
- Mainline macOS local packages keep `LSMinimumSystemVersion=14.0`.
- Monterey-compatible packages remain a separate build line.

## Standard Verification Commands

Run from `C1.source/privatevoice.src`:

```bash
npm --prefix frontend run build
go test ./...
GOOS=windows GOARCH=amd64 CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ go test -exec=/usr/bin/true ./...
./scripts/build-windows-preview.sh
./scripts/build-local-macos.sh arm64
./scripts/build-local-macos.sh x86_64
./scripts/build-local-macos-universal.sh
./scripts/verify-windows-qa-evidence.sh /path/to/qa-evidence-YYYYMMDD-HHMMSS.zip
```

## Known Gaps

- Windows runtime QA must still be performed on Windows 10/11 hardware before calling Windows stable.
- macOS 2.2.0 real-user test DMGs are locally signed and not notarized.
- Monterey compatibility was not revalidated for the 2.2.0 package set.
- Independent-site sales still need Developer ID release packaging, download page, authorization/activation, update strategy, support path, release manifest, and rollback policy.
