Users rate albums (0-6 scale), write reviews, curate lists, follow other listeners, and receive weekly recap digests. The system spans three client platforms (iOS, Android, web-ready backend) plus a shared TypeScript contracts package that defines the canonical API types. + +The codebase contains **154 source files** totaling **19,220 lines of code** across four targets: a Fastify + TypeScript backend (45 files, 5,531 LOC), a SwiftUI iOS app (67 files, 8,295 LOC), a Kotlin + Jetpack Compose Android app (33 files, 4,874 LOC), and a Zod-based contracts package (9 files, 520 LOC). The deep audit identified **33 issues** (2 P0, 8 P1, 14 P2, 9 P3), of which 3 have been fixed. The backend passes typechecking with zero errors and zero `as any` casts; iOS builds with zero warnings; Android builds successfully. Backend tests show 79 passing / 9 failing (pre-existing, not caused by the audit). + +Key strengths: fully parameterized SQL (zero injection risk), structured Pino logging, idempotency-key enforcement on all write routes, Zod-validated environment config, and solid MVVM architecture on both mobile platforms. Key weaknesses: iOS has zero test files, Android test coverage is approximately 15-20%, 8 of 11 backend modules lack tests, and 20 of 36 routes have no contract schema. The Spotify provider integration is still mocked. + +--- + +## System Architecture + +``` ++-------------------+ +-------------------+ +-------------------+ +| iOS App | | Android App | | (Future Web) | +| SwiftUI + MVVM | | Compose + MVVM | | | +| 13 screens | | 5 screens | | | ++--------+----------+ +--------+----------+ +--------+----------+ + | | | + +------------+------------+--------------------------+ + | + HTTPS / Bearer Auth + Idempotency-Key header + | + +-------v--------+ + | Fastify API | + | TypeScript | + | 11 modules | + | 36 routes | + +---+-------+----+ + | | + +-------v--+ +--v--------+ + | Postgres | | Redis | + | 23 tables | | cache | + | 9 migrate | | feed TTL | + +-----------+ +-----------+ + | + +------------+-------------+ + | | | ++----v----+ +----v-----+ +----v--------+ +| Spotify | | MusicBrz | | Gemini (AI) | +| OAuth | | Catalog | | Cadence bot | ++---------+ +----------+ +-------------+ +``` + +**Data flow:** Mobile clients authenticate via `/v1/auth/*` to obtain a Bearer token backed by a `sessions` table row.

Add iOS test coverage (P1, high impact) + +Zero test files is the largest quality gap. Start with: +- Unit tests for all 7 ViewModels (most critical: FeedViewModel, ProfileViewModel) +- Integration tests for APIClient and SoundScoreRepository +- Snapshot tests for key components (CadenceActionCards, AlbumRatingSheet) + +### 2. Wire Zod validation into Phase 2 handlers (P1) + +Replace all `request.body as {...}` type assertions with contract schema `.parse()` calls. This converts 500 errors on malformed input into 400 validation errors. Affects: `catalog.ts`, `import.ts`, `mapping.ts`, `providers.ts` (10+ handlers). + +### 3. Fix Android test suite (P1) + +- Fix 5 broken smoke test assertions to match current screen text +- Add ViewModel unit tests for all 5 ViewModels +- Add Repository tests with mocked API +- Target: bring coverage from 15% to 50%+ in one sprint + +### 4. Implement missing Android screens (P1) + +Priority order: AuthScreen (required for real users), AlbumDetailScreen (core feature), SettingsScreen, AIBuddyScreen, SplashScreen. + +### 5. Add account lockout (P2) + +Implement progressive lockout after N failed login attempts (e.g., 5 failures = 15-minute lockout). Current 10 req/min rate limit allows 14,400 password attempts per day. + +### 6. Connect real Spotify provider fetch (P2) + +Replace mock `fetchRecentPlays()` in `import.ts` with actual Spotify Recently Played API calls using the `spotify-adapter.ts` OAuth flow. + +### 7. Add mobile clients for Phase 2 routes (P1) + +Neither iOS nor Android can call any provider/mapping/sync routes. Add API client methods for at minimum: provider connect/disconnect, sync start/status. + +### 8. Resolve DTO field mismatches (P2) + +- Add `payload` to iOS `ActivityEventDto` +- Add `userId`, `topAlbums`, `createdAt` to iOS `WeeklyRecapDto` +- Remove orphan fields from iOS `Album` model (`spotifyId`, `genres`) +- Add `id` to both platforms' `UserProfile` model + +### 9. Wire ListsScreen into iOS tab bar (P1) + +Screen is fully built with ViewModel, ErrorBanner, and .refreshable but unreachable. Add a lists tab to `Tab.swift` or integrate via navigation link. + +### 10. Extract AuthViewModel for iOS (P2) + +Move login/signup business logic from inline `@State` in `AuthScreen.swift` to a proper ViewModel for testability. + +--- + +## Appendix: Source File Tree + +###

Tries login first, falls back to signup. +- **Token storage:** In-memory `accessToken: String?` only. No persistence across app restarts. +- **No AuthScreen.** Auto-authenticates silently on repository init. +- **No token refresh.** If token expires, next API call fails until app restart. + +--- + +## What Works + +1. **Glassmorphism design system** is visually consistent across both platforms. GlassCard, glass borders, dark elevated surfaces, and chrome text hierarchy create a cohesive look. +2. **Offline-first outbox architecture** is fully implemented on both platforms with idempotency keys, exponential backoff, and optimistic UI updates. +3. **Feed/Log/Search/Lists/Profile** core screens are present and functional on both platforms with matching layouts and data flows. +4. **Spotify artwork enrichment** (iOS) provides real album art on launch, significantly improving visual quality over gradient placeholders. +5. **AI Buddy (Cadence)** on iOS is a genuinely useful feature -- it can rate albums, draft reviews in the user's voice, and search Spotify, all with rich action cards. +6. **Theme system** (iOS) with 6 selectable themes and per-theme dark palettes gives users real personalization. +7. **Repository pattern** is cleanly separated on both platforms -- ViewModels never touch API/network directly. +8. **Combine pipeline** (iOS) and **Flow combine/stateIn** (Android) provide reactive, lifecycle-aware data flow. +9. **Deep link resolver** (Android) with `DeepLinkResolver.kt` and tests provides foundation for universal links. +10. **SeedData** on both platforms allows the app to function offline with realistic mock data immediately on launch. + +--- + +## What's Broken + +1. **Android is missing 4 screens:** AlbumDetailScreen, AIBuddyScreen, AuthScreen, SettingsScreen, SplashScreen. These are all functional on iOS. +2. **Android has no Spotify integration.** No artwork enrichment, no live search, no tracklist fetching. +3. **Android has no AI/Gemini integration.** No Cadence chat, no review drafting, no AI-assisted rating. +4. **Android auth has no persistence.** Token is in-memory only; lost on every app restart. No refresh token flow. +5. **Android has no theme switcher.** Single hardcoded Emerald theme vs. iOS's 6 selectable themes. +6. **iOS test coverage is zero.** No unit tests, no UI tests, no snapshot tests. Android has 4 test files (DeepLinkResolverTest, OutboxSyncEngineTest, ScreenSmokeTest, SoundScoreRepositoryMappingTest, ScreenPresentationTest). +7. **No strings.xml / Localizable.strings.** All user-facing text is hardcoded inline on both platforms. No i18n support. +8. **iOS SoundScoreRepository mutates state in-place** (e.g., `feedItems[index].isLiked.toggle()`, `albums[index].artworkUrl = url`). This violates immutability principles and can cause subtle SwiftUI update bugs. +9. **iOS Secrets.swift** likely contains hardcoded API keys (Spotify clientId/clientSecret, Gemini API key). These should be in build config or keychain. +10. **Android components are consolidated into 2 mega-files** (NewComponents.kt at 320 lines, PremiumComponents.kt at 301 lines) rather than one-component-per-file. This hurts discoverability and violates the codebase's own file organization conventions. +11. **No error retry UI on Android.** iOS has `ErrorBanner` with retry button; Android sync errors only show in SyncBanner. +12. **iOS Log/Feed screens have trending songs toggle** (GlassSegmentedControl) that Android lacks. +13. **No push notification implementation.** Both platforms have outbox ops for device token registration but no actual FCM/APNs integration. +14. **Weekly recap "Generate" is one-way.** Android can trigger generation via outbox, but there is no UI to initiate it from a button press. + +--- + +## Actionable Next Steps + +### P0 — Critical (blocks release) + +1. **Add Android AlbumDetailScreen.** Without it, users cannot view album details, rate albums, or see tracklists. Port from iOS's 454-line implementation. +2. **Add Android AuthScreen.** Silent dev-auth is not shippable. Port the iOS AuthScreen (180 lines) to Compose. +3. **Persist Android auth tokens.** Move from in-memory to EncryptedSharedPreferences. Add token refresh on 401. +4. **Move iOS secrets out of source.** Migrate Spotify/Gemini keys to xcconfig or build environment injection. + +### P1 — High (needed for quality parity) + +5. **Add Android SettingsScreen.** Port theme selection (with Material3 dynamic color or manual theme switching), notification toggles, export, delete account, sign out. +6. **Add Android SplashScreen.** Port the 6-phase animation or use Android 12+ SplashScreen API with a simpler fallback. +7. **Add Spotify integration to Android.** Create a SpotifyService class (Retrofit-based) mirroring the iOS actor. Wire into SearchViewModel and artwork enrichment. +8. **Split Android mega-component files.** Break NewComponents.kt and PremiumComponents.kt into individual files (AvatarCircle.kt, PillSearchBar.kt, SyncBanner.kt, etc.). +9. **iOS test coverage.** Add unit tests for ViewModels (FeedViewModel, LogViewModel, SearchViewModel) and OutboxStore. Target 80% on business logic. +10. **Extract all hardcoded strings.** Create strings.xml (Android) and Localizable.strings (iOS) with all user-facing copy. + +### P2 — Medium (polish and features) + +11. **Add AI Buddy to Android.** Port AIBuddyService, AIBuddyViewModel, AIBuddyScreen, and CadenceActionCards to Compose. +12. **Add Android theme switcher.** Port the 6-theme system (Emerald, Bonfire, Rose, Amethyst, Midnight, Gilt) with per-theme dark palettes. +13. **Fix iOS state mutation.** Refactor SoundScoreRepository to use immutable copy-on-write patterns instead of in-place array mutation. +14. **Add trending songs toggle to Android Feed.** Port GlassSegmentedControl and TrendingSongCard. +15. **Add error retry UI to Android.** Port iOS ErrorBanner component with retry callback. +16. **Wire push notifications.** Integrate FCM (Android) and APNs (iOS) with the existing device token registration outbox ops. + +### P3 — Low (nice to have) + +17. **Add Android deep link handling end-to-end.** DeepLinkResolver exists with tests but is not wired to navigation. +18. **Add iOS snapshot tests.** Capture GlassCard, StarRating, AlbumArtwork renders. +19. **Add rate-limiting/caching to Android API calls.** iOS has Spotify token caching and artwork cache; Android has neither. +20. **Add album art color extraction.** Both platforms use hardcoded AlbumColors. Use Palette (Android) or dominant-color extraction (iOS) from fetched artwork. diff --git a/docs/SoundScore_V1_Mobile_Architecture_Report.pdf b/docs/SoundScore_V1_Mobile_Architecture_Report.pdf new file mode 100644 index 0000000..7287e66 Binary files /dev/null and b/docs/SoundScore_V1_Mobile_Architecture_Report.pdf differ diff --git a/ios/README.md b/ios/README.md new file mode 100644 index 0000000..4ce6743 --- /dev/null +++ b/ios/README.md @@ -0,0 +1,286 @@ +# SoundScore iOS + +> Native iOS client — SwiftUI + MVVM + Combine + +## Architecture + +``` +┌─────────────────────────────────────────────────────────────┐ +│ ContentView │ +│ ┌──────┐ ┌──────┐ ┌──────┐ ┌──────┐ ┌──────┐ │ +│ │ Feed │ │ Log │ │Search│ │ AI │ │Profile│ │ +│ │Screen│ │Screen│ │Screen│ │Buddy │ │Screen│ │ +│ └──┬───┘ └──┬───┘ └──┬───┘ └──┬───┘ └──┬───┘ │ +│ │ │ │ │ │ │ +│ ┌──▼───┐ ┌──▼───┐ ┌──▼───┐ ┌──▼───┐ ┌──▼───┐ │ +│ │ Feed │ │ Log │ │Search│ │AIBudy│ │Profle│ │ +│ │ VM │ │ VM │ │ VM │ │ VM │ │ VM │ │ +│ └──┬───┘ └──┬───┘ └──┬───┘ └──┬───┘ └──┬───┘ │ +│ └────────┴────────┴────┬───┴────────┘ │ +│ │ │ +│ ┌─────────────▼──────────────┐ │ +│ │ SoundScoreRepository │ │ +│ │ (shared singleton) │ │ +│ └──────┬──────────┬──────────┘ │ +│ │ │ │ +│ ┌────────▼──┐ ┌──▼──────────┐ │ +│ │ APIClient │ │ OutboxStore │ │ +│ │ + SoundSc │ │ + SyncEngine │ │ +│ │ oreAPI │ └─────────────┘ │ +│ └────────┬──┘ │ +│ │ │ +│ ┌──────────────┼──────────────┐ │ +│ │ │ │ │ +│ ┌──▼──┐ ┌──────▼──┐ ┌─────▼────┐ │ +│ │Auth │ │ Spotify │ │AIBuddy │ │ +│ │Mngr │ │ Service │ │Service │ │ +│ └─────┘ └─────────┘ │(Gemini) │ │ +│ └──────────┘ │ +└─────────────────────────────────────────────────────────────┘ +``` + +**Data flow:** Screen observes ViewModel `@Published` properties via Combine. +ViewModel subscribes to `SoundScoreRepository.$property` publishers. +Mutations go through Repository, which queues an `OutboxOperation` for +optimistic local update, then flushes via `OutboxSyncEngine` to the API. + +## Screens + +| #

`https://soundscore-api.up.railway.app` + +### Secrets (`Config/Secrets.swift`) +- **Gitignored** (should be, but currently contains real keys) +- `spotifyClientId` — Spotify Client Credentials for artwork + search +- `spotifyClientSecret` — Spotify Client Credentials secret +- `geminiAPIKey` — Google Gemini 2.5 Flash key for Cadence AI + +## Theme System + +### SSColors (`Theme/SSColors.swift`) +- Theme-adaptive backgrounds: `darkBase`, `darkSurface`, `darkElevated` (delegate to ThemeManager) +- Glass tokens: `glassBg` (7% white), `glassBorder` (18% white), `glassFrosted`, `glassSheet` +- Chrome text: `chromeLight` (94%), `chromeMedium` (70%), `chromeDim` (44%), `chromeFaint` (24%) +- Semantic accents: `accentGreen`, `accentAmber`, `accentCoral`, `accentViolet` (fixed, not theme-dependent) +- Overlay levels: `overlayDark` (70% black), `overlayMedium`, `overlayLight` +- 10 album color palettes: forest, lime, ember, orchid, lagoon, rose, midnight, slate, coral, amber +- `Color(hex:alpha:)` extension for hex initialization + +### SSTypography (`Theme/SSTypography.swift`) +- System font with `.rounded` design throughout +- Display: 22pt bold, 28pt bold +- Headline: 18pt semibold, 22pt semibold +- Title: 14pt medium, 16pt semibold +- Body: 12pt regular, 14pt regular, 16pt regular +- Label: 10pt medium, 12pt medium, 14pt semibold + +### ThemeManager

darkBase/darkSurface/darkElevated) +- Persisted in UserDefaults under `ss_accentTheme` +- Legacy migration from old names (mint -> emerald, sunset -> bonfire, etc.) +- Settings screen renders swipeable `TabView` with live theme preview cards + +## Cadence AI + +### How It Works +1. **Model**: Gemini 2.5 Flash (`generativelanguage.googleapis.com/v1beta`) +2. **System prompt**: Includes personality instructions ("dorky, passionate music nerd"), album catalog with IDs, user taste context (ratings, genres, avg rating) +3. **Action parsing**: Response text is scanned for bracket-tagged actions: + - `[RATE:album_id:Album Title:4.5]` — renders `CadenceQuickRateCard` + - `[REVIEW:album_id:Album Title:review text]` — renders `CadenceReviewCard` + - `[SEARCH:query]` — triggers Spotify search, renders `CadenceSearchResultsCard` +4. **Batch ratings**: 3+ rate actions in one message render as `CadenceBatchRatingCard` +5. **Suggestion chips**: Context-aware follow-ups generated after each response +6. **Sound DNA Summary**: Separate Gemini call generates a 3-word sonic identity tagline, cached in UserDefaults + +### Actions +- Rate albums (single or batch) — writes to `SoundScoreRepository.updateRating()` +- Draft reviews in user's voice — saves via `SoundScoreRepository.saveReview()` +- Search for albums not in catalog — calls `SpotifyService.searchAlbums()` +- Add search results to library — appends to `SoundScoreRepository.albums` + +## Build + +```bash +# Open in Xcode +open ios/SoundScore/SoundScore.xcodeproj + +# Build from command line +xcodebuild

+|----|----------|-------------| +| ISSUE-007 | HIGH | `Secrets.swift` contains hardcoded Spotify and Gemini API keys in plaintext. Should be gitignored and use `.xcconfig` or a secrets manager. | +| ISSUE-008 | MEDIUM | `SoundScoreRepository` is a mutable singleton with `@Published var albums` — direct mutation of shared state from multiple screens. | +| ISSUE-009 | MEDIUM | `AuthManager` stores access/refresh tokens in `UserDefaults` (unencrypted). Should use Keychain. | +| ISSUE-010 | MEDIUM | `AlbumDetailViewModel` subscribes to repository publishers in `init` without cancellation guard — potential retain cycles. | +| ISSUE-011 | LOW | `ProfileViewModel.generateSoundDNA()` makes a raw Gemini API call with inline response decoding, duplicating `AIBuddyService` logic. | +| ISSUE-012 | LOW | `FeedItem.album` is a `var` — feed items mutated in-place for artwork enrichment. | +| ISSUE-013 | MEDIUM | No error retry UI — `errorMessage` is displayed but "Retry" only exists on `FeedScreen`. Other screens show errors without recovery. | +| ISSUE-014 | LOW | `SpotifyService` artwork cache is in-memory only — lost on app restart, causing re-fetches. | +| ISSUE-015 | MEDIUM | `OutboxStore` is in-memory — all pending operations lost on app termination. No CoreData/SQLite persistence. | +| ISSUE-023 | HIGH | 0% test coverage — no unit, integration, or UI tests. | +| ISSUE-024 | MEDIUM | `SeedData` contains 20 hardcoded albums with real Apple Music/Spotify artwork URLs that may change or break. | +| ISSUE-025 | LOW | `ContentView` creates `@StateObject` for `AuthManager.shared` and `SoundScoreRepository.shared` — wrapping singletons in `StateObject` is an anti-pattern. | +| ISSUE-028 | MEDIUM | `ThemeManager` uses `shared` singleton with `@Published` but is not an `@EnvironmentObject` in all views — some views access it directly via `ThemeManager.shared`. | +| ISSUE-029 | LOW | `buildTasteDNA()` is a global function in `PresentationHelpers.swift` doing genre aggregation, decade breakdown, and controversy detection — should be a method on a dedicated service. | + +## Feature Parity with Android + +| Feature | iOS | Android | Notes | +|---------|-----|---------|-------| +| Feed (trending + activity) | Yes | Yes | iOS adds trending songs toggle and curated lists section | +| Log / Diary | Yes | Yes | iOS adds songs mode toggle with per-track log entries | +| Search / Discover | Yes | Yes | iOS merges Spotify results; Android is local-only | +| Lists | Yes | Yes | Feature parity | +| Profile | Yes | Yes | iOS adds Taste DNA (genre bars, AI tagline, controversial pick) | +| Album Detail | Yes | No | iOS-only: hero artwork, tracklist, per-song ratings, songs breakdown | +| AI Buddy (Cadence) | Yes | No | iOS-only: Gemini-powered chat with agentic actions | +| Settings | Yes | No | iOS-only: theme switcher, notifications, quiet hours, data export, delete account | +| Auth (login/signup) | Yes | No | iOS has dedicated AuthScreen; Android auto-authenticates in repository | +| Splash Screen | Yes | No | iOS-only: animated theme cycling splash | +| Spotify Integration | Yes | No | iOS-only: artwork enrichment, search merge, track fetching | +| Per-Track Ratings | Yes | No | iOS-only: rate individual songs within album detail | +| Offline Outbox | Yes | Yes | Both use in-memory outbox with idempotency keys | +| Theme System | 6 themes (swipeable) | Material3 (single dark) | iOS has 6 custom themes; Android uses stock Material3 | + +--- + +*Last audited: 2026-03-19* diff --git a/ios/SoundScore/SoundScore/Components/CadenceActionCards.swift b/ios/SoundScore/SoundScore/Components/CadenceActionCards.swift index a95c90c..d7a8d82 100644 --- a/ios/SoundScore/SoundScore/Components/CadenceActionCards.swift +++ b/ios/SoundScore/SoundScore/Components/CadenceActionCards.swift @@ -288,7 +288,7 @@ struct CadenceBatchRatingCard: View { private func applyAllWithAnimation() { for (index, _) in ratings.enumerated() { DispatchQueue.main.asyncAfter(deadline: .now() + Double(index) * 0.3) { - withAnimation(.spring(response: 0.3, dampingFraction: 0.6)) { + _ = withAnimation(.spring(response: 0.3, dampingFraction: 0.6)) { appliedIndices.insert(index) } UIImpactFeedbackGenerator(style: .light).impactOccurred() diff --git a/ios/SoundScore/SoundScore/Services/APIClient.swift b/ios/SoundScore/SoundScore/Services/APIClient.swift index bb932d7..606d95c 100644 --- a/ios/SoundScore/SoundScore/Services/APIClient.swift +++ b/ios/SoundScore/SoundScore/Services/APIClient.swift @@ -135,6 +135,14 @@ final class APIClient { try await raw(method: "GET", path: path, authenticated: authenticated) } + func postRaw( + _ path: String, + body: Data?
