Update: MST Engineering AI has published a structured evidence contract for product diligence and a separate private-deployment boundary for customer engineering data.
The evidence contract
A qualifying product run identifies and hashes its engineering inputs, preserves parsed topology and provenance, binds approved component/interface facts, records native CAD execution, reopens the resulting assembly and returns a deterministic verdict or refusal reason.
The private deployment boundary
Customer P&IDs, component models, PDM knowledge and Rulepacks are not collected through the public website. A production engagement requires identity review, NDA, data-flow mapping, access control, retention policy, compliance review and a responsibility matrix.
Human engineering authority
The AI Engineer may prepare and verify an artifact within its declared scope. The customer engineering organization retains review and production-release authority.
Boundary: publication of this deployment model does not imply a universal security certification, customer endorsement or suitability for a specific regulated environment.
