- SQLite database at /home/seb/saltybot-data/social_memory.db
- Tables: persons (name, embeddings, relationship_tier, notes), encounters (person_id, timestamp, transcript, mood)
- ROS2 services: /saltybot/social_memory/lookup, /update, /encounter, /stats
- Automatic tier promotion by encounter count (5→regular, 20→favorite)
- Quality-based promotion: 80%+ positive interactions required
- Custom greetings per relationship tier (stranger/regular/favorite)
- Encounter tracking: transcript, mood, engagement_score, positive_interaction flag
- Face embedding storage support for face recognition integration
- Relationship score computation from interaction history
- Thread-safe concurrent service calls
- Periodic stats publishing on /saltybot/social_memory/stats_update
- Backup/restore functionality with gzip compression
- Full database statistics: person counts by tier, total encounters, database size
- Configurable via social_memory.yaml: thresholds, backup dir, publish interval

Two packages:
- saltybot_social_memory: Service definitions (CMake, ROS2 services)
- saltybot_social_memory_node: Python service server with SQLite backend
