requires:
  - phase: 06-desktop-client-ci-cd
    plan: 01
    provides: Tauri scaffold with server URL persistence
provides:
  - System tray with close-to-tray behavior
  - Window state persistence (size/position)
  - Autostart plugin registration
  - Startup version check with native notification
  - GET /health/version API endpoint
  - AppImage production bundle
affects: [desktop user experience, API health module]

tech-stack:
  added: [tauri-plugin-notification, tauri-plugin-autostart, tauri-plugin-window-state, reqwest]
  patterns: [close-to-tray, prevent-exit, async-version-check]

key-decisions:
  - "Both prevent_close (CloseRequested) AND prevent_exit (ExitRequested) per Pitfall 2"
  - "Async version check via reqwest — non-blocking, fire-and-forget"
  - "German tray labels: Oeffnen / Beenden"
  - "ImageMagick for icon generation (tauri icon not available headless)"
  - "NSIS target configured but only AppImage built (no Windows cross-compile toolchain)"

patterns-established:
  - "Close-to-tray: on_window_event hide + prevent_close, RunEvent::ExitRequested prevent_exit, tray quit -> app.exit(0)"
  - "Version check: spawn async task in setup, GET {server_url}/health/version, compare CARGO_PKG_VERSION"

# Phase 06 Plan 02: Native Desktop Features Summary

**Tray, close-to-tray, window-state, autostart, version check, branded icons, AppImage bundle**

## Performance

- **Duration:** 8 min
- **Commit:** c65ada0
- **Tasks:** 4 completed (3 auto + 1 build verification)
- **Files modified:** 4, icons generated: 3

## Accomplishments

- API GET /health/version endpoint (public, no auth)
- Tray icon with context menu (Oeffnen/Beenden) and left-click show
- Close-to-tray with both prevent_close and prevent_exit guards
- Window state persistence via tauri-plugin-window-state
- Autostart plugin registered with capability permissions
- Async startup version check with native notification on mismatch
- Tessera-branded icon (yellow T on dark bg, OKLCH palette)
- AppImage built: Tessera_0.0.1_amd64.AppImage

## Deviations from Plan

- Icons generated with ImageMagick instead of `tauri icon` (headless environment)
- NSIS bundle configured but not built (no Windows cross-compile toolchain on Linux host)

## Self-Check: PASSED

- cargo check passes with all 4 plugins
- API type-check passes
- AppImage produced at target/release/bundle/appimage/
