# Brief 1: pgvector migration + SCHEMA_MAP
|
|
|
|
## Goal
|
|
|
|
Add `vector(1024)` embedding column + HNSW index on `cards`.
|
|
|
|
## Acceptance criteria
|
|
|
|
- [ ] `CREATE EXTENSION IF NOT EXISTS vector`
|
|
- [ ] `cards.embedding`, `cards.embedded_at`
|
|
- [ ] `idx_cards_embedding_hnsw` partial index
|
|
- [ ] SCHEMA_MAP documents layer 0 + pgvector
