A model file is not just an inert spreadsheet. Its format and loading mechanism can create software-security concerns that belong in deployment planning.
Scikit-learn's persistence guidance discusses security and compatibility considerations for stored models. Scikit-learn — model persistence.
Establish the origin
Use an approved source and a controlled handling process for model artefacts. Do not load an unsolicited file merely because its name resembles the expected version. Preserve the relevant provenance and integrity evidence.
Preserve the environment
For a product-classification tool, keep the dependency information needed to reproduce the validated behaviour. A file that loads in a different environment is not automatically equivalent to the evaluated system. Treat successful loading and acceptable performance as separate checks.
