Module cache 

Model and weight cache directory resolution.

Local providers download model weights to a per-provider, per-model directory. This module determines where that directory lives based on (in priority order):

1. A per-model cache_dir option in the spec’s JSON options.
2. The UNI_CACHE_DIR environment variable (global root override).
3. A default .uni_cache/ directory relative to the working directory.

Constants

CACHE_ROOT_ENV

The environment variable used to override the root cache directory.

Functions

resolve_cache_dir

Resolve the cache directory for a given provider and model.

resolve_provider_cache_root

Resolve the root cache directory for a provider (no model sub-directory).

sanitize_model_name

Replace / with -- and strip characters that are unsafe in directory names.
