[Unreleased]¶

ShakeGrid.sample and ShakeGrid.sample_g: values at many positions in one NumPy call, nearest (the same values as value_at, ties to even like round) or bilinear; NaN outside the grid. On 100,000 points of a real grid: 10 ms against 280 ms for a loop, identical to Limen's parser.
IngvClient.info / parse_info → ShakeMapInfo: the map's info.json (version, status, history of runs, GMPE, stations, peaks), a few kB to tell whether the 12 MB grid changed.
IngvClient.stations / parse_stations → Station: the stations of stationlist.json, PGA in g, with the model's prediction. The string "null" INGV writes for a missing value is read as None.
IngvClient.uncertainty: uncertainty.xml as a ShakeGrid (STDPGA in ln g).
IngvClient.product and shakemap_product_url: any file of the map's products.
updated_after on events and event_query (FDSN updatedafter).

IngvClient: INGV FDSN events and ShakeMap grids, async, with an injectable httpx.AsyncClient, retries and a send hook. A 204 is no events, a 404 is no ShakeMap, any other failure raises IngvError.
parse_grid / ShakeGrid: every column of a ShakeMap 4 grid.xml, values at a point (pga_g in g, pgv_cm_s, mmi, value_at), arrays, the event and the map's status. The row order is checked, not assumed.
parse_events / Event, event_query, shakemap_grid_url: the FDSN side, as pure functions.
Extracted from Limen (src/limen/integrations/ingv/). On three real grids the PGA matches Limen's parser value for value.
