Version 1.0.2 (build 1): the app now tracks its version/build in app_version.dart (lines 3-4), so backend checks and the update workflow know exactly when to prompt users. Mandatory update experience: update_screen.dart (lines 1-274) renders the animated release note panel and launch button, always highlighting that the build contains critical security and telemetry fixes. Version service: version_service.dart (lines 155-233) fetches the latest version/release notes from the /version endpoint, compares semver plus build numbers, and exposes store URLs plus release messaging for the UI chips.
