They can help explain the actual knowledge and process, but their existence alone neither proves nor defeats the specialized-knowledge claim.
Explain the applicant’s use of the documented process
Identify relevant sections, actual training and examples of interpreting complex results. Distinguish the applicant’s contribution from work performed by others. Handle sensitive material appropriately and do not invent secrecy or uniqueness as a requirement. The evidence should explain the knowledge actually used in the proposed assignment.
Useful items include the system manual and its revision history, the crop recipe library with dates showing internal development, the calibration and validation procedures, incident and fault records demonstrating the reasoning applied, and training curricula showing the months required to bring a grower to competence.
Start with the artifact: a dated specification, patent filing, validation report or software repository log that shows the proprietary process exists and when it was developed. Avoid replacing every meaningful detail with an unexplained claim of confidentiality; discuss suitable supporting evidence and secure handling with the reviewer.
