A glossary can explain terms but should not be treated as a substitute for required evidence.
Separate explanation from the record
Identify the source documents and applicable preparation requirements. Do not alter their meaning or omit relevant facts merely to simplify the technical account.
Make an evidence index separating completed training, authored project versions, supervisor records, and entity documents from courses that remain only planned. Do not confuse confidential information with specialized knowledge automatically: confidentiality may explain handling, but the record still must establish the category's substantive standard. Use the system's own outputs to keep the cost down, since quality systems already record authorship, approvals, and audit participation, and much of the evidence can therefore be produced by running reports rather than by writing narratives. Redact commercially sensitive figures rather than withholding entire documents, since a redacted record with its identifier and date intact still shows a system operating and a person inside it. Many confidential documents are not evidence of specialized knowledge, and many strong L-1B cases can be explained without giving a reviewer unrestricted access to commercially sensitive material.
