9- The isolated Python 3.13 suite passed 43 tests. Synthetic checks cover masked
10 indices/calibration, terrain with known planes, raster output metadata, classification
11 masks/labels/CRS, refusal to overwrite existing files, and corrected local recipes.
12- Public STAC GET searches at Planetary Computer, Earth Search and CDSE each returned
13 two Sentinel-2 L2A items plus next-page links. Separate PySTAC Client searches followed
14 pagination and bounded results to three items per catalog, checking collection/cloud
15 filters. These are metadata tests, not imagery or authenticated download tests.
16- A local ODC-STAC 0.5.3 load preserved raw DN values despite asset scale/offset metadata;
17 callers must calibrate explicitly once. Real local COG, GeoParquet and Zarr 2 round trips,
18 Dask raster/vector, Fiona, PyKrige, ESDA, MovingPandas, OSMnx and watershed checks passed.
19- Desktop QGIS/ArcPy/GRASS/SAGA, native GDAL, R/Julia/Java/Go/Rust, GPUs and real-scene
20 ML/physical calibration were not executed. Their examples are illustrative and
21 use referenced current interfaces; source review is not runtime validation.
22- No authenticated Earth Engine/CDS/Google/Mapbox/OpenWeather calls, service mutations,
23 cloud exports, training jobs, commercial image orders or pretrained weights were used.
