## 🎯 Implementation Overview

### What We're Building

**Goal:** Integrate AC moods with ATProto to enable federated mood sharing

**Strategy:** Dual-write pattern with MongoDB primary, ATProto secondary

**Key Features:**
1. New moods auto-sync to ATProto
2. Historical moods can be backfilled
3. Delete syncs to both systems
4. Graceful degradation if ATProto unavailable
5. No risk to existing moods

### Architecture Summary

```
User → /api/mood → MongoDB (primary) → Success
                 ↘ ATProto (secondary) → Federated

Deletion → MongoDB (delete) + ATProto (delete) → Both cleared

Migration → Find unsaved moods → Create ATProto records → Update MongoDB
```

### Schema Changes

**MongoDB moods collection** gets new optional field:
```javascript
atproto: {
  uri: "at://did:plc:abc.../computer.aesthetic.mood/3k...",
  cid: "bafyrei...",
  created: Date,
  synced: true
}
```

**ATProto PDS** gets new record type:
```javascript
{
  $type: "computer.aesthetic.mood",
  text: "feeling good",
  createdAt: "2025-10-14T12:00:00Z",
  mongoId: "abc123"  // Back-reference
}
```

## 🚀 Quick Start Path

### For Developers

1. **Read:** `MOODS-GET-STARTED.md` (10 min)
2. **Review:** `MOODS-ARCHITECTURE-DIAGRAM.md` (15 min)
3. **Study:** `MOODS-ATPROTO-INTEGRATION-PLAN.md` (45 min)
4. **Track:** Use `MOODS-INTEGRATION-CHECKLIST.md` during implementation

### For Project Managers

1. **Read:** `MOODS-INTEGRATION-SUMMARY.md` (5 min)
2. **Review:** `MOODS-INTEGRATION-CHECKLIST.md` for milestones
3. **Reference:** `MOODS-ATPROTO-INTEGRATION-PLAN.md` for detailed tasks

### For QA/Testing

1. **Read:** `MOODS-INTEGRATION-SUMMARY.md` (5 min)
2. **Focus:** Phase 5 section in `MOODS-ATPROTO-INTEGRATION-PLAN.md`
3. **Use:** `MOODS-INTEGRATION-CHECKLIST.md` Section: Phase 5 Testing

## 📅 Timeline

**Estimated Duration:** 3-4 weeks

- **Week 1:** Lexicon + Backend Integration
- **Week 2:** Deletion Sync + Migration Script
- **Week 3:** Backfill + Testing + Verification
- **Week 4:** Documentation + Production Launch

**Effort:** ~40-60 hours of development work

**Risk Level:** Low (MongoDB stays primary, ATProto is additive)

---

## 🎓 Key Concepts

### Dual-Write Pattern
- Write to MongoDB first (primary)
- Write to ATProto second (secondary)
- If ATProto fails, MongoDB still succeeds
- Background job can retry failed syncs

### Graceful Degradation
- Users without ATProto accounts → MongoDB only
- ATProto PDS down → MongoDB only
- No user-facing errors

### Bidirectional References
- MongoDB → ATProto: via `atproto.uri` field
- ATProto → MongoDB: via `mongoId` field
- Enables full audit and sync verification

### Time-based IDs (TID)
- ATProto uses TID for chronological ordering
- Format: `3k...` (base32 encoded timestamp)
- Ensures moods appear in correct order

## 🔍 Files to Create During Implementation

### Phase 1
- `scripts/create-mood-lexicon.mjs` - Deploy lexicon to PDS

### Phase 2
- `system/backend/mood-atproto.mjs` - Helper functions:
  - `createAtprotoMood()`
  - `deleteAtprotoMood()`
  - `deleteAllAtprotoMoods()`

### Phase 3
(Update existing files, no new files needed)

### Phase 4
- `scripts/migrate-moods-to-atproto.mjs` - Backfill historical moods

### Phase 5
- `scripts/audit-mood-atproto-sync.mjs` - Verify sync status

**See full code samples in:** `MOODS-ATPROTO-INTEGRATION-PLAN.md`

## 📊 Success Metrics

### Implementation Complete When:
- ✅ Lexicon deployed to PDS
- ✅ New moods auto-create ATProto records
- ✅ Historical moods backfilled
- ✅ Account deletion removes ATProto moods
- ✅ Audit shows 100% sync rate
- ✅ All tests passing
- ✅ Documentation complete
- ✅ Monitoring in place

### Target Metrics:
- **Sync Success Rate:** >99%
- **Sync Latency:** <1 second
- **Backfill Complete:** 100% of eligible moods
- **Zero Breaking Changes:** Existing functionality unchanged

---

## 🚨 Important Notes

### What This DOES
✅ Adds ATProto support to moods  
✅ Enables federated mood discovery  
✅ Maintains MongoDB as primary  
✅ Gracefully handles ATProto failures  
✅ Backfills historical data  
✅ Syncs deletions

### What This DOESN'T Do
❌ Replace MongoDB with ATProto  
❌ Require ATProto for moods to work  
❌ Change existing mood functionality  
❌ Break existing integrations  
❌ Expose private data (unless user chooses)
