🎯 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:

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 #

  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)
