DiskCache

DiskCache(base_dir=None, model=None, *, max_entries_per_model=20)

One-file, full-key-verified atomic NetCDF result cache.

Entries live at <root>/<model>/<parameters>-<full-sha256>.nc. Contents have an independently checked full key and schema; legacy files are never reused. The directory is a trusted local cache, not an untrusted file reader.
