Launcher Upgrade Spec

Goal

Upgrade LanMountainDesktop.Launcher into the unified Launcher for:

  • OOBE first-run entry
  • startup splash window
  • silent/incremental/rollback update
  • plugin install/update

Scope (Phase 1)

  • Avalonia GUI launcher with two windows:
    • OOBEWindow (first run only)
    • SplashWindow (every launch)
  • Default command launch
  • CLI commands:
    • update check|download|apply|rollback
    • plugin install|update
  • Legacy compatibility:
    • --source --plugins-dir --result still works for plugin install

Update Behavior

  • ClassIsland-style deployment folders:
    • app-<version>-<number>/
    • marker files .current, .partial, .destroy
  • Signed file map:
    • files.json
    • files.json.sig
    • public-key.pem
  • Incremental update:
    • replace from archive
    • reuse from current deployment
    • delete skip file in target deployment
  • Rollback:
    • snapshot metadata is written before apply
    • automatic rollback on apply failure
    • manual rollback via command

OOBE and Splash

  • OOBE is independent from splash.
  • OOBE shows only:
    • welcome text: 欢迎使用阑山桌面
    • arrow button for continue
  • Splash shows only:
    • app name: 阑山桌面

Extensibility

  • IOobeStep for future multi-step OOBE
  • ISplashStageReporter for future startup progress visualization
