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
