compute_hydrology_indices — TWI + HAND from the DEM via whitebox
fetch_ida_hwms — STN API → ida_2021_hwms_ny.geojson

run_prithvi_ida — Ida-specific pre/post diff variant
build_{nycha,schools,mta_entrances}_register
— full FSM pass over each register's
rows, JSON cached to data/registers/
audit — full evidence audit per query for the
printable report
dry_run — end-to-end CLI smoke without uvicorn
These run offline, on a fat workstation; only their outputs land in
