Answer.
A C3PAO assesses your implementation of the NIST SP 800-171 controls protecting CUI — for AI components that means audit logging (AU), system integrity and monitoring (SI), access control, and configuration management evidence around the model and its data. The assessor wants documented, repeatable proof, not assertions. Planisphere can produce the reproducible model-behaviour record that backs the SI/AU-flavoured controls; the C3PAO renders the assessment verdict, Planisphere does not.
