# Job-Info-Test → Job-Info-Prod Migration Plan

## Current State: Job-Info-Test ✅

**Status:** Documentation Complete, Architecture Confirmed

### What Exists
- ✅ Functional PocketBase + Microsoft OAuth integration (half-working)
- ✅ Hono backend with Redis caching
- ✅ Frontend with auth.js and index.html
- ✅ Tailwind CSS + PostCSS setup
- ✅ Comprehensive professional documentation (8 docs)
- ✅ Architecture specification with dual-token system

### What's Documented
```

### Key Requirements Now Clear
1. **Dual-token system** (PocketBase + Microsoft Graph)
2. **Always-warm tokens** via background refresh loop
3. **Zero re-authentication** after initial login
4. **Field-deployed app** for construction workers
5. **Offline-first** with graceful degradation

## Phase 1: Job-Info-Prod Scaffolding (Ready)

**Note:** `Job-Info-Prod` is a **temporary staging folder** for safety. Once everything is verified working, it will **replace** Job-Info-Test entirely. The separate folder is just to keep things safe during development.

### ✅ Pre-Work Complete
- ✅ Architecture documented (OPUS_PROMPT_PHASE1.md)
- ✅ Requirements clarified
- ✅ Tech stack specified
- ✅ Rules documented
- ✅ Patterns established

### 🔄 Next: Run Opus 4.5 Scaffolding

**Input:**
- OPUS_PROMPT_PHASE1.md (671 lines of detailed architecture)
- Supporting docs from auth/ folder

**Output:**
- Complete Job-Info-Prod folder structure
- All service files (tokenService, cacheService, pocketbaseService, graphService)
- Route handlers with proper patterns
- Frontend components scaffolding
- Configuration templates
- Tests structure
- Professional documentation

**Duration:** ~30 minutes with Opus 4.5

## Phase 2: Implementation (Sonnet 4.5)

### Backend Implementation
```
Routes:
├── /api/auth/login-callback       (Initial token setup)
├── /api/auth/logout               (Clear cache + stop refresh)
└── /api/refresh-token             (Get fresh tokens)

Services:
├── TokenRefreshService            (30-min background loop)
├── CacheService                   (Valkey operations)
├── PocketBaseService              (PocketBase integration)
└── GraphService                   (Microsoft Graph integration)

Middleware:
├── Auth verification              (Token validation)
└── Error handling                 (Consistent responses)
```

### Frontend Implementation
```
Auth:
├── TokenClient                    (ensureToken pattern)
├── PocketBase setup               (Client initialization)
└── Refresh loop startup           (On app init)

Views:
├── Sign in page                   (OAuth flow)
├── Jobs list                      (Main app)
├── Job detail + files             (File operations)
└── Notes page                     (Sticky notes)

Services:
├── API client                     (Token injection)
├── Cache service                  (Local file caching)
├── Offline handler                (Graceful degradation)

```

**Duration:** ~4-6 hours with Sonnet 4.5

## Phase 3: Integration & Testing

### What Gets Tested
- ✅ Dual-token obtention in single OAuth flow
- ✅ Token storage (localStorage + Valkey)
- ✅ Background refresh loop (every 30 minutes)
- ✅ API calls with token injection
- ✅ Offline fallback with stale tokens
- ✅ Error handling & graceful degradation
- ✅ Logout clears all tokens

### Files to Create
- Tests for token lifecycle
- Tests for background refresh
- Tests for offline mode
- Documentation for each component

---

## Phase 4: Production Deployment

### Pre-Deployment Checklist
- [ ] All tests passing
- [ ] Error logging configured
- [ ] Performance testing done
- [ ] Security review complete
- [ ] Documentation finalized
- [ ] Deployment guide created

### Deployment Steps
1. Build frontend (Tailwind + TypeScript)
2. Build backend (Hono + TypeScript)
3. Deploy to server
4. Configure Valkey/Redis
5. Set environment variables
6. Start background services
7. Test end-to-end

✅ **All requirements documented** (RULES.md)
✅ **Tech stack enforced** (TECH_STACK.md)
✅ **Professional structure planned** (In prompt)
✅ **Code examples provided** (In prompt + RULES.md)

### What's Next
1. Share OPUS_PROMPT_PHASE1.md with Opus 4.5
2. Opus scaffolds Job-Info-Prod structure
3. Share scaffolding output with Sonnet 4.5
4. Sonnet implements functionality
5. Merge and test
6. Deploy to production

## Note on Architecture

This dual-token, always-warm-cache approach is specifically designed for:
- **Field workers** who can't afford re-authentication delays
- **Intermittent connectivity** in field environments
- **Mission-critical reliability** - app must always work
- **Enterprise integration** - PocketBase + Microsoft ecosystem

It's not overkill, it's the right tool for the job. ✨
