- Add /profile GET endpoint returning Ikario + David projections on 100 directions
- Compute Ikario state from Weaviate StateVector v1 + 113 thoughts
- Compute David tensor from user messages (SQLite) + declared profile
- Map direction categories to StateTensor dimensions via CATEGORY_TO_DIMENSION
- Calculate david_similarity as average cosine across 8 dimensions
- Result: 60.93% Ikario-David similarity (vs 100% when initialized from same source)
