Current Gap Analysis (2026-02-15)

What we have now

• Backend gateway architecture with REST + fake implementations, typed DTOs, retries, refresh, and tests.
• OpenAPI + ADR documentation baseline.
• Product UI shell with responsive desktop/mobile navigation and key views.
• Offline-safe default behavior with fake backend mode.

What is still missing

• Local database persistence and repository wiring (currently demo in-memory data).
• Full CRUD flows (create/edit/delete) for people, captures, reminder rules, gift/event ideas.
• Auth UX flows (sign-in, session-expired recovery, sign-out confirmation).
• Conflict policy UI and merge/resolution UX for rejected remote/local mutations.
• Notifications/reminders delivery and scheduling integration.
• End-to-end and integration tests for app flows beyond unit/widget basics.

Implementation Plan (Next)

Phase 1: Data Foundation

1. Introduce local DB schema + repository interfaces for core entities.
2. Replace LocalRepository demo data with persisted data access.
3. Add migration/test coverage for DB reads/writes.

Phase 2: Core Product Flows

1. Build People CRUD and detail editing screens.
2. Build Moments/Captures create-and-list workflows.
3. Add Ideas and Reminder Rule management.

Phase 3: Sync + Auth UX

1. Add background sync scheduling/triggers (app start, manual retry, connectivity hooks).
2. Add conflict handling strategy and user-facing UI states for rejected mutations.
3. Add session-expired recovery UX and guarded routes for protected actions.

Phase 4: Quality + Release Readiness

1. Add CI for analyze/test and optional build smoke checks.
2. Expand widget/integration tests for primary user journeys.
3. Add observability hooks and production hardening pass.

Current Status

The Flutter app now includes a production-grade backend integration scaffold with an offline-first posture:

• Local/offline UX remains primary; backend is optional for core usage.
• A transport-agnostic gateway interface is in place.
• REST implementation with auth refresh/retry/error mapping is implemented.
• Deterministic fake gateway is available for local/dev without backend.
• OpenAPI contract + ADR + setup docs + unit tests are in place.
• flutter analyze and flutter test are passing.

What Was Implemented

1. Core Config + Theme Shell

• Added backend config with build-time + runtime override:
  • lib/core/config/app_config.dart
• Added lightweight app theme aligned with reference style direction:
  • lib/core/config/app_theme.dart
• Updated app entry shell and Riverpod root:
  • lib/main.dart

2. Network Foundation

Implemented a Dio stack with request metadata, auth, refresh, retry, and error mapping:

• lib/core/network/dio_factory.dart
• lib/core/network/network_constants.dart
• lib/core/network/backend_exception.dart
• lib/core/network/dio_error_mapper.dart
• Interceptors:
  • lib/core/network/interceptors/request_metadata_interceptor.dart
  • lib/core/network/interceptors/auth_interceptor.dart
  • lib/core/network/interceptors/refresh_token_interceptor.dart
  • lib/core/network/interceptors/retry_interceptor.dart

Behavior implemented:

• Adds per-request X-Request-Id.
• Adds Authorization: Bearer <token> when session exists.
• On 401, attempts one refresh (/v1/auth/refresh) then retries original request.
• If refresh fails, session is cleared and AuthExpiredException surfaced.
• Retry policy (max 2 retries, exponential backoff):
  • Retry transient failures (timeouts, connection, 5xx).
  • Safe methods (GET/HEAD/OPTIONS) retry automatically.
  • Non-idempotent endpoints only retry when Idempotency-Key exists.
• Maps Dio failures into typed backend exceptions with metadata.

3. Auth Token Storage

• Interface:
  • lib/core/auth/token_store.dart
• Production implementation:
  • lib/core/auth/secure_token_store.dart
• Test/dev implementation:
  • lib/core/auth/in_memory_token_store.dart

4. Backend Integration Layer

Domain boundary and implementations:

• Interface:
  • lib/integrations/backend/backend_gateway.dart
• REST:
  • lib/integrations/backend/backend_gateway_rest.dart
• Fake:
  • lib/integrations/backend/backend_gateway_fake.dart
• Optional Riverpod providers:
  • lib/integrations/backend/backend_gateway_provider.dart
• Sync validation:
  • lib/integrations/backend/sync_envelope_validator.dart

Implemented methods:

• sign-in/out + me
• sync pull/push (with idempotency key on push)
• signals feed + ack
• upload init + download URL scaffold

Offline-first hardening:

• signOut() clears local token store in finally, even when network call fails.

5. Typed Models (Freezed + JSON)

• lib/integrations/backend/models/backend_models.dart
• Generated files:
  • backend_models.freezed.dart
  • backend_models.g.dart

Includes DTOs/enums for:

• Auth (SignInRequest, AuthSession, refresh request/response, UserProfile)
• Sync (ChangeEnvelope, push/pull requests/results, ack/rejection)
• Signals (SignalsFeed, SignalItem, ack request/action)
• Uploads (UploadInitRequest/Result, DownloadUrl)

6. Contract + Architecture Docs

• OpenAPI spec:
  • docs/api/openapi.yaml
• ADR:
  • docs/ADR/0002-backend-protocol-rest-openapi.md
• Setup instructions:
  • docs/SETUP.md
• Previous concise checklist log:
  • docs/PROGRESS.md

7. Tooling + Quality

• Strict analyzer/lints:
  • analysis_options.yaml
• Dependencies added in pubspec.yaml:
  • runtime: dio, freezed_annotation, json_annotation, flutter_secure_storage, uuid, clock, flutter_riverpod
  • dev: freezed, json_serializable, build_runner, mocktail

8. Test Coverage Added

• helper adapter: test/helpers/queue_http_client_adapter.dart
• updated smoke widget test: test/widget_test.dart

Verification Snapshot

Most recent local checks:

• flutter analyze -> pass
• flutter test -> pass

Known Gaps / Intentional Scope Limits

• No realtime transport yet (SSE/WebSocket intentionally deferred).
• No backend-generated client code from OpenAPI yet.
• No persistence layer wiring to local DB yet (gateway is ready to plug in).
• No UI features using backend gateway yet beyond app shell readiness.
• Fake gateway data is deterministic sample content, not scenario-configurable yet.

Handoff Plan For Next Agent Sessions

Priority 1: Repository Hygiene + CI

1. Add CI workflow for flutter analyze + flutter test.
2. Add branch protections / PR template if desired.
3. Keep generated files committed policy explicit in README.

Priority 2: Local DB Integration (Offline-First Core)

1. Define local domain entities and repositories for person, capture, giftIdea, eventIdea, tag, reminderRule.
2. Map local mutations to ChangeEnvelope and enqueue for sync.
3. Create sync orchestrator service that:
   • pushes pending local mutations,
   • applies pull changes with conflict policy,
   • stores/advances cursor.
4. Add tests for conflict handling and cursor progression.

Priority 3: App Wiring + UX

1. Replace local demo repository data with actual local DB repositories.
2. Add create/edit flows for people, captures, reminders, and ideas (forms + validation).
3. Add session state and auth entry screens (sign-in, expired-session recovery).
4. Add explicit offline badges and sync conflict resolution UI.

Priority 4: Security + Hardening

1. Add central log redaction helper for headers/bodies.
2. Add token-expiry pre-check strategy (optional proactive refresh).
3. Evaluate secure storage behavior on web target and fallback policy.
4. Add tests for concurrent 401 refresh race conditions.

Priority 5: API Evolution

1. Version strategy in OpenAPI (/v1 already set).
2. Define backend error payload schema formally in OpenAPI.
3. Add capabilities endpoint for future realtime negotiation.
4. Add SSE/WebSocket design ADR when backend is ready.

How To Continue Quickly

1. Run: flutter pub get
2. If models change: dart run build_runner build --delete-conflicting-outputs
3. Validate: flutter analyze && flutter test
4. Start from:
   • gateway surface: lib/integrations/backend/backend_gateway.dart
   • sync transport: lib/integrations/backend/backend_gateway_rest.dart
   • contract: docs/api/openapi.yaml

Important Notes

• Current default base URL is placeholder (https://api.example.com).
• Use fake mode for local iteration:
  • flutter run --dart-define=USE_FAKE_BACKEND=true
• Build-time URL override:
  • flutter run --dart-define=BACKEND_BASE_URL=<your-url>
