## Architecture Summary

### Dual-Token System

```
┌─────────────────────────────────────────────────────┐
│              AUTHENTICATION FLOW                     │
└─────────────────────────────────────────────────────┘

[User Login]
    ↓
[PocketBase OAuth (includes Microsoft scopes)]
    ↓
[Obtain 2 Tokens]
    ├─ PocketBase Token
    └─ Microsoft Graph Token
    ↓
[Store Locally]
    ├─ localStorage.pocketbase_auth
    ├─ localStorage.graph_token
    └─ localStorage.token_expires_*
    ↓
[Send to Backend]
    ↓
[Backend Caches in Valkey]
    ├─ tokens:userId:pb
    ├─ tokens:userId:graph
    └─ tokens:userId:refresh_*
    ↓
[Start Background Refresh Loop]
    ├─ Every 30 minutes
    ├─ Check token expiry
    ├─ Refresh if expiring
    └─ Update both cache & localStorage
    ↓
[User Never Re-authenticates Again]
    ├─ Tokens always fresh
    ├─ Works offline with stale tokens
    └─ Only restart resets auth
```

### Single Token Check Pattern

```
[API Call Needed]
    ↓
[ensureToken('pb')]
    ├─ Get from localStorage
    ├─ Check if fresh (> 15 min remaining)
    │   ├─ YES → Return immediately
    │   └─ NO → Try backend refresh
    │       ├─ Backend has fresh → Return
    │       ├─ Backend down → Use stale token
    │       └─ No token → Redirect to login
    └─ Make API call with token
```

---

## Critical Requirements (Now Documented)

### ✅ Requirement 1: Dual Tokens
- Both PocketBase and Microsoft Graph tokens
- Obtained in single OAuth flow
- Both must stay fresh independently

### ✅ Requirement 2: Always-Warm Cache
- Background refresh every 30 minutes
- Tokens refreshed BEFORE expiry
- Invisible to user

### ✅ Requirement 3: Zero Re-Authentication
- After initial login, NEVER re-authenticate
- Except for system restart (unavoidable)
- Field workers design requirement

### ✅ Requirement 4: Offline-First
- Works without backend connectivity
- Uses stale tokens as fallback
- Caches file lists and content
- Queues operations for sync

### ✅ Requirement 5: Mission-Critical Reliability
- Designed for field conditions
- Intermittent internet acceptable
- App must always work
- Graceful degradation when down

## Key Insights

### What Changed Your Understanding
1. **Dual tokens** - Not just PocketBase
2. **Always-warm cache** - Not lazy refresh
3. **Zero re-auth** - Mission-critical requirement
4. **Field workers** - Can't afford login delays
5. **Offline-first** - Core feature, not afterthought

### Why This Architecture
- **Reliability** - Designed for mission-critical field work
- **User experience** - One login, never again
- **Resilience** - Works offline with graceful fallback
- **Enterprise** - Integrates with Microsoft ecosystem
- **Simplicity** - Single token check pattern everywhere

### Why Dual Storage
- **Frontend localStorage** - Immediate access
- **Backend Valkey cache** - Automatic refresh
- **Resilience** - Either one failing doesn't stop app
- **Fallback** - If one source fails, other works
- **Sync** - Cache keeps everything in sync
