# Relationship Saver Progress Log

Updated: 2026-02-23

## Collaboration Rule (Carry Forward)

- After every sensible code/documentation change set, create a git commit as
  the last step so the next agent session can pick up from clean checkpoints.

## Latest Milestone (2026-02-23): Relationship Graph Preview + Full-Screen Explorer

Reworked the graph interaction model to be mobile-friendly on the dashboard and
still support smooth pan/zoom exploration.

- `lib/features/dashboard/dashboard_view.dart`
  - refactored graph rendering into a shared canvas widget with two modes:
    - `preview` (dashboard, scroll-first)
    - `explorer` (full-screen, pan/zoom-first)
  - dashboard graph card is now a scroll-safe preview:
    - keeps node long-press for `Person Insights`
    - disables pan/zoom interaction on the dashboard canvas
    - adds explicit `Explore` / `Open Explorer` CTA button
    - updated helper copy to clarify dashboard preview vs explorer behavior
  - added full-screen `Relationship Graph` explorer page:
    - pan enabled
    - pinch-to-zoom enabled
    - `Reset view` control
    - same long-press-to-open-person-insights behavior
    - shared legend display
  - extracted shared graph helpers (legend + navigation helpers) to keep the
    preview and explorer behavior consistent

- `test/features/dashboard/dashboard_graph_interactions_test.dart`
  - extended coverage to verify:
    - dashboard preview renders `Explore` CTA
    - explorer page opens from dashboard
    - `Reset view` action is available and works
    - returning to dashboard still works

- UX decision captured in implementation
  - dashboard remains scroll-first on mobile (no hidden pan-mode toggle)
  - graph exploration happens in a dedicated full-screen context

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-22): Quick-Capture Dialog Regression Test (People)

Added explicit widget-test coverage so controller lifecycle issues in quick
capture dialogs are caught automatically in CI/local runs.

- `test/features/people/people_quick_capture_dialog_test.dart` (new)
  - mounts `PeopleView` in mobile layout
  - opens profile-context `Capture` quick action dialog
  - exercises `Cancel` path and pumps through dismissal frames
  - reopens dialog, saves a capture, and pumps through dismissal frames
  - asserts:
    - no framework exceptions surfaced (`tester.takeException() == null`)
    - local moments count increases after save
  - specifically protects against the disposed `TextEditingController` race

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-22): Quick-Capture Dialog Controller Lifecycle Fix

Fixed a runtime crash when creating captures/notes from profile-context quick
actions (`TextEditingController was used after being disposed`) caused by a
dialog animation/disposal race.

- Root cause
  - quick-capture dialogs in `People` and graph `Person Insights` created a
    local `TextEditingController`, passed it into `showDialog(...)`, then
    disposed it immediately after `await showDialog(...)`
  - the dialog route can still rebuild during dismiss animation, which caused
    the `TextField` to touch a disposed controller

- Fixes
  - `lib/features/people/people_view.dart`
    - replaced ad-hoc quick text capture dialog with stateful
      `_QuickTextCaptureDialog` that owns and disposes its controller internally
  - `lib/features/dashboard/dashboard_view.dart`
    - replaced ad-hoc quick text capture dialog with stateful
      `_InsightQuickTextCaptureDialog` with the same lifecycle fix
  - both dialogs now also show inline `Required` validation instead of silent
    no-op when pressing save with empty text

- Similar issue scan
  - searched the codebase for the same anti-pattern (local
    `TextEditingController` created outside dialog widget and disposed after
    `showDialog`)
  - no remaining occurrences found after patching these two flows

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-22): Preference Review UI (People + Graph Insights)

Exposed the new chat-derived preference signals in the main person detail
surfaces and added a user review loop to confirm or dismiss inferred context.

- `lib/features/people/people_view.dart`
  - added `Chat-derived preferences` section to the People detail workspace
  - shows inferred/confirmed/dismissed signals sorted by status/confidence
  - per-signal actions:
    - `Why?` (evidence preview bottom sheet)
    - `Confirm`
    - `Dismiss`
  - evidence preview includes:
    - signal metadata (category/polarity/confidence)
    - evidence snippets extracted from shared chat messages
    - source app list
  - added explicit `Close` action in evidence sheet (better UX + testability)

- `lib/features/dashboard/dashboard_view.dart`
  - added matching `Chat-derived preferences` section to graph long-press
    `Person Insights` page
  - same confirm/dismiss/why review flow and evidence preview
  - keeps profile review experience aligned between People page and graph flow

- `test/features/dashboard/dashboard_graph_interactions_test.dart`
  - extended graph interaction test to:
    - seed an inferred preference signal
    - assert section renders in `Person Insights`
    - open `Why?` evidence preview
    - confirm signal and verify local status updates to `confirmed`

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-22): MVP Chat Preference Extractor + Ingest Enrichment

Implemented the first local semantic-enrichment pass so shared chat messages can
start building inferred person preferences automatically.

- `lib/features/local/chat_preference_extractor.dart` (new)
  - added a pure Dart, local-first rule-based extractor
  - extracts evidence-backed preference candidates from message text:
    - `prefer X over Y` (creates like/dislike pair)
    - `favorite ... is ...`
    - `I love/like/enjoy ...`
    - `I hate/dislike/don’t like ...`
    - `allergic to ...`
  - adds category heuristics (e.g. drink/food/hobby/environment/health)
  - returns confidence-scored candidates with evidence snippets

- `lib/features/local/local_repository.dart`
  - integrated extractor into resolved shared-message ingest flow
  - when a chat share is imported and linked to a profile:
    - store raw shared message + capture moment (existing behavior)
    - extract preference candidates from message text
    - upsert local inferred preference signals with evidence + source metadata

- Tests
  - `test/features/local/chat_preference_extractor_test.dart` (new)
    - extractor unit coverage for positive/negative/comparative/allergy patterns
  - `test/features/local/local_repository_test.dart`
    - added ingest test proving shared chat import creates inferred signals

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-22): Local Preference Signal Scaffolding (Inferred/Confirmed)

Added a local-first data model and repository APIs for chat-derived preference
signals so the app can gradually build profile context from shared messages.

- `lib/features/local/local_models.dart`
  - new enums:
    - `PreferenceSignalPolarity` (`like`, `dislike`, `neutral`)
    - `PreferenceSignalStatus` (`inferred`, `confirmed`, `dismissed`)
  - new model:
    - `PersonPreferenceSignal`
      - key/category/label
      - confidence
      - status
      - first/last seen timestamps
      - occurrence count
      - evidence message ids/snippets
      - source apps
  - `LocalDataState` now stores `preferenceSignals`
    - added `copyWith`, `toJson`, `fromJson` support (backward-compatible with
      existing stored state)

- `lib/features/local/local_repository.dart`
  - added local-only repository APIs:
    - `upsertInferredPreferenceSignalObservation(...)`
      - aggregates repeated observations
      - merges evidence and source apps
      - updates confidence and occurrence count
    - `upsertPreferenceSignal(...)`
    - `setPreferenceSignalStatus(...)`
    - `confirmPreferenceSignal(...)`
    - `dismissPreferenceSignal(...)`
  - updated person lifecycle consistency:
    - deleting a person removes linked preference signals
    - merging profiles rebinds source preference signals to target
    - remote person delete application also removes preference signals
  - intentionally local-only for now (not yet mapped to backend sync envelopes)

- `test/features/local/local_repository_test.dart`
  - added coverage for inferred signal upsert aggregation + status transitions

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-22): Person Editor Inline Validation + Duplicate Warning

Improved the People add/edit profile experience to make validation explicit and
support safer profile creation in a sharing-first workflow.

- `lib/features/people/people_view.dart`
  - added inline required-field validation for `Name` and `Relationship`
    (no more silent no-op when save is pressed with empty required fields)
  - added live duplicate-name warning banner in add/edit form:
    - checks normalized profile names against existing local profiles
    - excludes the current profile during edit
    - warns before save while still allowing save (with follow-up merge flow)
  - routed existing profile list into the responsive editor panel/sheet so
    duplicate detection works on mobile + desktop/web

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-22): Responsive People Add/Edit Form (Sheet + Dialog)

Aligned the People profile creation/edit flow with the newer insights-style UI
language and improved platform-specific presentation behavior.

- `lib/features/people/people_view.dart`
  - replaced the old `AlertDialog` person editor with a shared responsive form
    panel:
    - mobile (`<720px`): `showModalBottomSheet` with a rounded sheet layout
    - desktop/web/tablet: larger custom dialog panel
  - added richer form UX with:
    - hero preview (avatar + live preview chips for name/relationship/location/tags)
    - grouped sections (`Identity`, `Context`) matching the People/Insights card
      style
    - preserved existing labels and `Save` action text for test compatibility
  - kept add/edit repository behavior unchanged (local-first)
  - fixed narrow-width section header overflow discovered by widget test

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-22): People Page UX Redesign (Insights-Aligned)

Reworked the `People` page to feel closer to the graph long-press `Person
Insights` experience and improved the compact/mobile interaction flow.

- `lib/features/people/people_view.dart`
  - redesigned the selected person detail area into an insights-style workspace:
    - hero summary card with quick actions (`Capture`, `Idea`, menu + edit/delete)
    - stats tiles (affinity, next moment, captures, ideas)
    - section cards for:
      - profile context (relationship/location/tags/source links + notes)
      - ideas
      - moments
      - reminders
      - shared message history
  - added richer person list cards:
    - next moment pill
    - optional location pill
    - tag pills
  - added People list controls:
    - search
    - relationship filter chips
    - sort menu (affinity / next / A-Z)
    - empty state when filters yield no results
  - improved compact/mobile flow:
    - selected profile workspace now renders above the full list (instead of
      after all profiles)
    - explicit `All profiles` section header with count
  - improved add-person flow UX:
    - newly created person is automatically selected/focused immediately
    - also fixed the mobile CRUD widget test expectation after layout changes
  - migrated page-local filter state to Riverpod 3 `Notifier` providers
    (instead of unavailable legacy `StateProvider` API)

- Validation
  - `flutter analyze` -> pass
  - `flutter test` -> pass

## Latest Milestone (2026-02-18): Quick-Add Actions on Graph Person Insights

Closed a UX gap where long-pressing a graph node opened person insights without
the expected context add action.

- Added `Quick add` menu to person profile header in graph-based insights page:
  - `lib/features/dashboard/dashboard_view.dart`
  - supports:
    - Add Capture

navigation:

- Added duplicate-profile merge operation in local repository:
  - `lib/features/local/local_repository.dart`
  - new `mergePersonProfiles(sourcePersonId, targetPersonId)`:

    - rebinds related records from source -> target:
      - moments
      - ideas
      - reminders
      - source links

## 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

Core network and model tests:

- `test/core/network/token_refresh_interceptor_test.dart`
- `test/core/network/dio_error_mapper_test.dart`
- `test/core/network/retry_interceptor_test.dart`
- `test/integrations/backend/backend_models_serialization_test.dart`
- `test/integrations/backend/sync_envelope_validator_test.dart`
- 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>`
