## What You Understood

### Initial Requirements (Incomplete)
❌ "Single token only"
❌ "PocketBase OAuth but no Graph tokens"
❌ "Users can re-authenticate when needed"

### **Actual Requirements (Now Documented)** ✅
✅ **Dual tokens**: PocketBase + Microsoft Graph (in single OAuth flow)
✅ **Always-warm cache**: Background refresh loop (every 30 min)
✅ **Zero re-authentication**: After initial login, never again (except system restart)
✅ **Field-deployed**: Workers with intermittent internet
✅ **Mission-critical**: Must be bulletproof
✅ **Offline-first**: Graceful degradation when backend unavailable

---

## Architecture Decisions Documented

### Problem
Field construction workers can't afford frequent re-authentication. Internet is intermittent. App must always work.

### Solution: Dual-Token with Background Refresh
```
[Single OAuth Login]
    ↓
[Get 2 Tokens: PocketBase + Graph]
    ↓
[Store in localStorage + Valkey cache]
    ↓
[Start Background Refresh Loop (30 min)]
    ↓
[User Never Re-authenticates]
    ↓
[If Frontend Token Expires]
    → [Backend Provides Fresh One]
    → [Or Use Stale Token if Backend Down]
    ↓
[App Always Works]
```

### Why This Works for Field Workers
- **One-time authentication** (login on first day)
- **Tokens always fresh** (automatic background refresh)
- **Works offline** (graceful fallback to stale tokens)
- **No interruptions** (never prompts user during work)
- **Mission-critical reliability** (designed for field conditions)

## Critical Architecture Principles

### ✅ MUST Follow These Rules

1. **Dual Tokens (Never Single)**
   - PocketBase token for app operations
   - Microsoft Graph token for SharePoint
   - Both obtained in single OAuth flow
   - Both must stay fresh independently

2. **Always-Warm Cache (Never Lazy Refresh)**
   - Backend refresh loop every 30 minutes
   - Tokens refreshed BEFORE expiry
   - Users never see token expiration
   - Invisible to user (background process)

3. **Zero Re-authentication After Login**
   - User authenticates once at startup
   - Never prompted again (except system restart)
   - Field workers can't afford interruptions
   - Designed for mission-critical reliability

4. **Offline-First with Graceful Degradation**
   - Works without backend connectivity
   - Uses stale tokens if refresh fails
   - Caches file lists and content
   - Queues operations for sync

5. **Single Token Check Pattern**
   ```javascript
   // Before EVERY API call
   const token = await ensureToken('pb'); // or 'graph'
   // Returns: fresh token OR stale token OR throws
   // Never manually refreshes - let backend handle it
   ```

## Risk Mitigation

### Potential Issues & How They're Handled

| Risk | How It's Handled |
|------|-----------------|
| Token expires during API call | Backend refresh provides fresh one |
| Backend unavailable | Use stale token + queue for sync |
| Network flaky | Retry with exponential backoff |
| User loses token | Can get from Valkey cache |
| Cache expires | Frontend token still available |
| Worker offline for hours | All operations queued locally |
| System restart | User must re-authenticate (unavoidable) |
