🎯 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:

New moods auto-sync to ATProto
Historical moods can be backfilled
Delete syncs to both systems
Graceful degradation if ATProto unavailable
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:

atproto: {
  uri: "at://did:plc:abc.../computer.aesthetic.mood/3k...",
  cid: "bafyrei...",
  created: Date,
  synced: true
}

ATProto PDS gets new record type:

{
  $type: "computer.aesthetic.mood",
  text: "feeling good",
  createdAt: "2025-10-14T12:00:00Z",
  mongoId: "abc123"  // Back-reference
}

🚀 Quick Start Path#

For Developers#

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

For Project Managers#

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

For QA/Testing#

Read: MOODS-INTEGRATION-SUMMARY.md (5 min)
Focus: Phase 5 section in MOODS-ATPROTO-INTEGRATION-PLAN.md
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)
