Do not load untrusted experiment files: only deserialize experiment files (JSON, YAML) that originate from a trusted source. Treat serialized experiment files with the same caution as executable scripts.

Validate file provenance: when receiving experiment files from external parties (e.g. for support or collaboration), verify their origin before loading them.

Audit serialized files: before loading, inspect serialized experiment files and verify that only trusted classes are listed as deserializers.
