 ## API
 - `POST /api/query` → `QueryRequest` → `QueryResponse`
+- `POST /chart/positions` → `{when_utc, lat, lon, objects?}` → pozycje obiektów (LOG-01)
+- `POST /chart/report` → `{when_utc, lat, lon, limit?}` → wynik obliczeń wyszukany w bazie: z pozycji generuje sygnifikatory (planeta w znaku) i zwraca pasujące interpretacje z warstwy danych (zalążek LOG-16/18/19)
 - `POST /chart/positions` → `{when_utc, lat, lon, house_system?}` → pełny horoskop: pozycje (LOG-01) + osie i domy (LOG-05). `house_system`: `whole_sign` (dom.) / `equal` / `porphyry`.
 - `POST /chart/compare` → jak wyżej → raport różnic dwóch silników (LOG-26; wymaga silnika B)
 - `GET /health` (sprawdza też warstwę bazodanową)
