Identity: rename the application identity to com.companionglp.glpcompanion on every platform (Android applicationId/namespace + MainActivity package, iOS/macOS bundle IDs incl. RunnerTests, Windows CompanyName/copyright, web manifest id, Supabase OAuth redirect scheme).
Deep links: register the custom scheme com.companionglp.glpcompanion:// in iOS/macOS Info.plist (CFBundleURLTypes), the Android VIEW/BROWSABLE intent-filter, and Windows per-user HKCU protocol registration. Server-side steps (Supabase uri_allow-list, Entra optional email claim) are recorded in BUILD_STATE.md.
Windows runner: single-instance mutex (Local\GLPCompanionSingleInstance) so login callbacks are delivered deterministically; SendAppLinkToInstance forwarding with foreground/taskbar-flash fallback so protocol activation can never look like a hang; protocol diagnostics appended to TEMP glpcompanion-protocol.log.
macOS: add the missing com.apple.security.network.client entitlement so the sandboxed runner can reach Supabase at all.
Auth UX: surface deferred OAuth/magic-link handshake failures as snackbars on the login screen; make isAuthenticatedProvider reactive (watches authStateProvider) with a microtask-deferred router refresh so live sign-in and sign-out redirect correctly; add a debug package:logging listener so supabase_flutter diagnostics are visible under flutter run.
Field-verified on Windows: Google, Microsoft (Entra ID), and email magic-link sign-in round trips plus sign-out redirect to /login.
Domain (pure Dart):
- Add 12-quadrant InjectionSite anatomical model with a least-recently-used
rotation policy, DoseEntry entity, and Glp1Compound value object
(Semaglutide 168h, Tirzepatide 120h, Liraglutide 13h)
- Add CalculateSerumLevel use case implementing
C(t) = sum(D_i * 0.5^((t - t_i) / t_half))
- Define IMedicationRepository contract; retire superseded MedicationDose
Data:
- Add injection-history CRUD to AppDatabase (watch/get/insert/update/delete/
latest-administered), ordered newest first
- Implement drift-backed MedicationRepository with record-to-entity mapping
Presentation and local alerts:
- Add MedicationController (StateNotifier) managing serum estimation, site
rotation suggestions, and best-effort reminder scheduling
- Rework MedicationScreen: serum card, suggested-site card, interactive log
dialog (compound, dosage, timestamp, quadrant), history with delete, and a
60s decay ticker
- Add INotificationService / PlatformNotificationService wrapping
flutter_local_notifications (one-shot scheduling on Android/iOS/macOS,
graceful no-op on Web/Windows/Linux), Android boot receivers for reminder
restoration, and the timezone dependency
Development tooling:
- Add debug-only "Continue Without Signing In" bypass on the login screen,
backed by an in-memory devAuthBypassProvider; the router guard honors the
flag and the shell shows a dev-mode banner while active
Fixes:
- Resolve the Supabase client lazily in SupabaseAuthService so widget tests
and pre-initialization builds no longer throw
Testing:
- 36 new tests covering PK decay math, rotation determinism, repository CRUD
on an in-memory drift database, controller behavior with fakes, and the
end-to-end dev bypass flow; full suite green (37/37)
- BUILD_STATE.md: mark Phase 2 complete and record all verification gates
