## API Integration

### Main API: `https://api.digital-home.site`
- Auth: JWT Bearer token with auto-refresh via `/auth/refresh`
- AuthManager stores token + refreshToken in UserDefaults
- APIService.authManager weak ref enables transparent 401 → refresh → retry

**Endpoints used:**
- Auth: login, register, me, refresh
- Profile: GET/PUT /profile
- Tasks: CRUD + complete/uncomplete, priorities 1-3 (not 4!)
- Habits: CRUD + log (sends `date` not `completed_at`), freezes, stats
- Habits frequency: iOS uses daily/weekly/monthly/interval internally, sends `custom` to API for monthly/interval
- Finance: transactions, categories (field is `emoji` not `icon`), summary, analytics
- Savings: categories, transactions (date required!), stats (includes monthly_payment_details, overdues), recurring plans

### Health API: `https://health.digital-home.site`
- Separate JWT auth (hardcoded credentials in HealthAPIService)
- API key for data sync: `health-cosmo-2026`
- Server code: `/Users/daniilklimov/Personal/health-webhook` (Node.js + SQLite)

**Data flow:**
1. Apple Watch → HealthKit on iPhone
2. App collects from HealthKit → POST /api/health?key=API_KEY
3. health-webhook stores JSON files → parses on GET requests
4. App displays from GET /api/health/latest, /readiness, /heatmap

**HealthKit metrics collected:**
- step_count, heart_rate, resting_heart_rate, heart_rate_variability
- active_energy (kcal→kJ), blood_oxygen_saturation, walking_running_distance
- respiratory_rate, sleep_analysis (with phase breakdown: deep/rem/core/awake + timestamps)

**Sleep format for webhook:**
```json
{"totalSleep": 7.5, "deep": 1.2, "rem": 2.0, "core": 4.3, "awake": 0.5,
 "inBedStart": "...", "sleepEnd": "...", "source": "Apple Watch"}
```

**API response field mapping (CodingKeys):**
- `spo2` → `bloodOxygen` (BloodOxygenData)
- `respiratoryRate` → as-is
- `distance` → as-is
- `activeEnergy` → as-is

## Design System
- **Background:** `#06060f` (deep dark)
- **Accent:** `#0D9488` (teal)
- **Glass cards:** `.glassCard()` modifier — ultraThinMaterial + gradient fill + gradient stroke
- **Glow icons:** `GlowIcon` — circle with blur glow behind
- **Tab bar:** Custom VStack-based (not standard TabView), each tab has its own glow color
- **All sheets:** `.presentationDetents([.large])`, background `Color(hex: "06060f")`
- **Color pickers:** LazyVGrid 5 columns (not HStack — overflow on small screens)
- **App icon:** Glassmorphism style, Assets.xcassets/AppIcon.appiconset

## Key Design Decisions & Gotchas
- **Buttons in ScrollView/List MUST have `.buttonStyle(.plain)`** — otherwise taps get swallowed
- **Tracker rows:** Separate tap zones — `.onTapGesture` on text area for edit, `Button` with `.buttonStyle(.plain)` for checkbox
- **`try?` is avoided in save functions** — errors are shown in UI via `@State errorMessage`
- **Tab bar uses VStack, not ZStack** — prevents content overlap
- **onChange uses iOS 17+ syntax:** `{ }` not `{ _ in }`
- **XcodeGen:** All capabilities must be in project.yml, manual Xcode changes get reset

## Background Sync
- BGProcessingTask: `com.daniil.pulsehealth.healthsync`
- Scheduled every ~30 minutes
- Collects HealthKit data and POSTs to health-webhook
- Registered in App.init(), scheduled in .onAppear

## External Services & Paths
- **Pulse API source:** `/Users/daniilklimov/digital-home/pulse-api` (Go)
- **Pulse Web source:** `/Users/daniilklimov/digital-home/pulse-web` (React)
- **Health webhook:** `/Users/daniilklimov/Personal/health-webhook` (Node.js)
- **Infrastructure docs:** `~/Obsidian/daniil/Инфраструктура`

## Known Issues / TODO
- Finance tab is owner-only (user.id === 1) in web, no such restriction in iOS
- Savings members endpoints (multi-user) not implemented in iOS
- Auth: password change works via direct URLRequest, not through APIService
- Health readiness `activity.value` from API shows different step count than latest (different time periods)
