- db/Dockerfile: postgis:16-3.4 + postgresql-16-pgvector (works around the
EOL bullseye release files: disable Check-Valid-Until, add pgdg repo)
- 20-vector.sql: CREATE EXTENSION vector on first boot
- embed/main.go (embedpoi): build poi_vec from poi — zembed embeddings of
'name — kind' (2560-d), resumable, HNSW cosine index at the end
- main.go: /semantic endpoint (embeds q with the local model, cosine <=>
over poi_vec, returns lat/lng/score); add lat/lng to /near /nearest
/corridor so the UI can pin results; bind the vector as a text literal
+ ::vector cast (lib/pq has no []float32 codec)
- mock/app.js: poi_semantic tool + poi_near now returns coords; agent loop
drops poi_near/poi_semantic results as map pins (showSpatialPins)
- mock/styles.css: .sp-dot / .sp-card pin + popup styles
- README: document the pgvector stack + embedpoi
