 ## What This Is
 
-A local-first Flutter app for organizing household chores and one-time projects, built for personal/couple use on Android. Takes the room-based task scheduling model (inspired by BeTidy), strips cloud/account/social features, and wraps it in a calm, minimal Material 3 UI. Fully offline, free, privacy-respecting — all data stays on-device.
+A local-first Flutter app for organizing household chores, built for personal/couple use on Android. Uses a room-based task scheduling model where users create rooms, add recurring tasks with frequency intervals, and the app auto-calculates the next due date after each completion. Features a daily plan home screen, bundled German-language task templates, room cleanliness indicators, and daily summary notifications. Fully offline, free, privacy-respecting — all data stays on-device.

 ## Context
 
-- Inspired by BeTidy (iOS/Android household cleaning app) — taking the proven room-based model, removing cloud/social, refining the UI
+- Shipped v1.0 MVP with 10,588 LOC Dart (7,773 lib + 2,815 test), 89 tests
+- Tech stack: Flutter + Dart, Riverpod 3 + code generation, Drift 2.31 SQLite, GoRouter, flutter_local_notifications
+- Inspired by BeTidy (iOS/Android household cleaning app) — room-based model, no cloud/social
 - Built for personal use with partner on a shared Android device; may publish publicly later
-- Code and comments in English; UI strings German-only for MVP
-- Room photos are nice-to-have for MVP — icon-only rooms are sufficient initially
-- Developer is new to Drift (SQLite ORM) — plan should account for learning curve
+- Code and comments in English; UI strings German-only for v1.0
 - Gitea (self-hosted on Hetzner) for version control; no CI/CD pipeline yet

 ## Key Decisions
 
 | Decision | Rationale | Outcome |
 |----------|-----------|---------|
-| Riverpod over Bloc | Modern, compile-safe, less boilerplate, Dart-native | — Pending |
-| Drift over raw sqflite | Type-safe queries, compile-time validation, migration support | — Pending |
-| Android-first | Primary device is Android; iOS follows | — Pending |
-| German-only MVP | Primary user language; defer localization infrastructure | — Pending |
-| No CI initially | Keep scope focused on the app itself | — Pending |
-| Calm Material 3 palette | Muted greens, warm grays, gentle blues — calm productivity, not playful | — Pending |
-| Clean Architecture | Feature-based folder structure with data/domain/presentation layers | — Pending |
+| Riverpod 3 over Bloc | Modern, compile-safe, less boilerplate, Dart-native | Good — code generation works well, @riverpod annotation reduces boilerplate |
+| Drift over raw sqflite | Type-safe queries, compile-time validation, migration support | Good — DAOs with stream queries provide reactive UI, migration workflow established |
+| Android-first | Primary device is Android; iOS follows | Good — no iOS-specific issues encountered |
+| German-only MVP | Primary user language; defer localization infrastructure | Good — ARB localization infrastructure in place from Phase 1, ready for English |
+| No CI initially | Keep scope focused on the app itself | Good — manual dart analyze + flutter test sufficient for solo dev |
+| Calm Material 3 palette | Muted greens, warm grays, gentle blues — calm productivity | Good — sage & stone theme (seed 0xFF7A9A6D) with warm charcoal dark mode |
+| Clean Architecture | Feature-based folder structure with data/domain/presentation layers | Good — clear separation, easy to navigate |
+| Calendar-anchored scheduling | Monthly/quarterly/yearly tasks anchor to original day-of-month with clamping | Good — handles Feb 28/31 edge cases correctly with anchor memory |
+| flutter_local_notifications v21 | Standard Flutter notification package, TZ-aware scheduling | Good — inexactAllowWhileIdle avoids SCHEDULE_EXACT_ALARM complexity |
+| Manual StreamProvider for drift types | riverpod_generator throws InvalidTypeException with drift Task type | Revisit — may be fixed in future riverpod_generator versions |
