## Development Status

### Web Application (mnemo_cards_web_v2)
- **Framework**: Flutter Web
- **Status**: Active development
- **Key Features**: Vocabulary learning, testing, statistics
- **Recent Updates**:
  - Added card voice support (metadata, API, web playback with error UI)
    - New voices collection linked to cards and protected endpoints for list/mp3 (Bearer)
    - Web playback: download bytes via authenticated API and play from memory (fixes 401 on `<audio src>` without headers)
    - Added unit tests for voice metadata fetching and voice-bytes download
  - Card UI: moved voice play icon into a `Stack` overlay so it doesn't take an extra row on the card (with widget test coverage)
  - CardViewer UI: navigation arrows are constrained under the card on wide screens; favorites (heart) is now part of the card (top-right); voice controls moved to top-left (header text stays centered)
    - Added widget test coverage for wide-screen navigation + header control positioning
  - Pack details: "Перемешать" button no longer has an active (pressed) state (widget test updated)
  - Pack details: Control buttons (Сетка/Карточки, Перемешать, Избранные) now hide text when there's not enough space, showing only icons (widget tests added)
  - Pack details: removed the "view" (eye) icon on cards; moved the favorite (heart) icon to the top-right corner (list + grid) (widget test updated)
  - Added app version display on authentication page
  - **UI Components Refactoring**: Extracted authentication components
    - Created `SignInWithGoogleButton` component for Google authentication

  - Added widget tests for themed question cards, exit control, and interactive-only notice
  - Timer/progress now sourced from live session state on `game_page.dart`
  - Fixed broken game navigation: `TestPage` now pushes `/game/:id` so Exit/Finish/Back work (incl. deep-link fallback) + widget tests
- **Game Tests Package**: Started shared package `games/packages/game_tests`
  - Added configurable `GameTestSettings` (sounds/haptics/delay)
  - Integrated into `mnemo_cards_web_v2` via `TestsModule`/`TestsStateManager`

    - Admin: question type selector + matrix size form; JSON (de)serialization + vitest coverage
  - **CardViewer Carousel Looping**: Implemented infinite carousel scrolling for card viewer
    - Cards now loop seamlessly: last card → first card and first card → last card
    - Works for both swipe gestures and navigation buttons
    - Added comprehensive unit tests for looping functionality
  - **Loading Screens Enhancement**: Replaced basic loading screens with themed images
    - Removed CircularProgressIndicator as requested
    - Added sun image (el_sol.png) for light theme and moon image (la_luna.png) for dark theme
    - Updated both initialization placeholder and app loading screens to use theme-aware images

### Mobile Application (mnemo_cards)
- **Framework**: Flutter
- **Status**: Active development
- **Key Features**: Cross-platform mobile app

### Backend (mnemo_cards_backend)
- **Framework**: Dart with Shelf
- **Status**: Production ready
- **Key Features**: API, authentication, data management
- **Recent Updates**:
  - **Card Voices: Stop Returning base64**: `/api/v2/packs/.../voices` now returns a direct `url` to audio
    - Admin voice uploads are persisted to `data/voice/` and DB stores only a file name (no base64)
    - Public voice list heals legacy base64-in-DB by migrating to file on first read
    - `/api/v2/voice/<voiceId>` serves bytes (or redirects for remote URLs)
  - **Admin Tests: Stop Returning base64 Images**: `/api/v2/admin/tests/<id>` now returns image **links**, never base64
    - Self-heals legacy base64/data-url values on read by persisting them into `data/cards/` and storing only a `cardId` in DB
    - Normalizes admin round-trip values (`/api/.../cards/<id>/image` → `<cardId>`) so editing tests doesn't pollute DB with API URLs
    - When linking a test to a pack, automatically links all referenced image cards to that pack so `/api/v2/packs/<packId>/cards/<cardId>/image` works
    - Added focused backend unit test: `mnemo_cards_backend/test/api/v2/admin_tests_api_v2_image_urls_test.dart`
  - **User Telegram Field**: Added telegram field to user model
    - Added `telegram` field to `UserModel` and `UserDto` alongside `email`
    - Added `telegram` column to `users` table in database (migration v2→v3)
    - Updated all authentication flows (Google OAuth, Telegram Web App, Telegram bot)
    - Telegram usernames now stored in `telegram` field instead of `email`
    - Added comprehensive unit tests for UserModel and UserDto telegram field
    - Migration automatically moves telegram usernames from email to telegram field
  - **Generated Tests Cleanup**: Fixed generated tests accumulating over time
    - Fixed linking bug: generated tests were created in DB but not linked to packs (caused orphan tests)
    - Added cron cleanup to purge orphan `version='generated'` tests and hard-delete old soft-deleted generated tests (TTL)
    - Added DAO helpers and a focused unit test for the cleanup logic
    - Added regression test to ensure `updateGeneratedTests()` creates a pack link
  - **Matrix Test (image selection)**: Added matrix question generator + API storage support (cards auto-generated if missing)
  - **MinIO Migration**: Migrated file storage from local filesystem to MinIO object storage
    - Created MinioService for MinIO operations (upload, presigned URLs, delete, fileExists)
    - Created MediaApiV2 with endpoints for file uploads (card-image, test-image, voice) and presigned URL generation
    - Updated AdminCardsApiV2 and AdminTestsApiV2 to upload files to MinIO instead of local disk
    - Updated PacksApiV2 and TestManager to generate presigned URLs and embed them in DTOs
    - Updated DTOs (GameCardDto, VoiceDto, TestDto) to include presigned URL fields
    - Added unit tests for MinioService and MediaApiV2
    - **Admin Panel Updates**: Updated admin panel components for MinIO integration
      - Updated ImageUpload component: uploads via Media API, saves objectId, previews via presigned URLs
      - Updated AudioUpload component: uploads via Media API, saves objectId
      - Updated BulkCardUpload: batch uploads via Media API with progress indicators
      - Updated preview logic: uses presigned URLs from backend when available
      - Created Media API client (mediaApi) for file uploads
    - **Web App Updates**: Updated web app for MinIO integration
      - Updated DTOs in mnemo_cards_common: added imageUrl/imageBackUrl/presignedUrl fields to all relevant DTOs
      - Updated test question DTOs: added imageUrl to SimpleTestQuestionBody, InputButtonsTestQuestionBody, TestButtonDto, MatrixCardDto
      - Updated backend test_manager: adds imageUrl while keeping image (objectId) for questions and buttons
      - Updated all card display widgets: card_viewer, card_flipper, pack_details_page, pack_card_item to use imageUrl from DTO
      - Updated test widgets: matrix_widget, answer_options, question_display to use presigned URLs
      - Updated tests_state_manager: converts TestButtonDto and MatrixCardDto to use imageUrl when available
      - All widgets maintain backward compatibility with fallback to ApiConfigV2 URL building
