LMS Technical Validation

Summary​

Validation occurs across four layers:

  • Value records require/normalize course code/title and certificate value; clamp duration/result; validate training-period date order.
  • Endpoint helpers require strings, parse enums/material type/CSV values, verify referenced records, and enforce selected lifecycle guards.
  • Database configuration enforces required/max-length, tenant uniqueness, link uniqueness, and completion uniqueness.
  • Tenant context requires a tenant for writes, while global query filters scope tenant entities/evidence.

Domain entities mostly have public setters and no invariant methods. No FluentValidation or separate validator classes exist. Duplicate guards include tenant/course code, tenant/employee/course, completion/enrollment, path/course, event ID, and certificate value. Error handling mixes direct HTTP results, domain-validation middleware, external-service exceptions, and database failures. Fine-grained authorization/ownership validation is not confirmed.

Requires confirmation​

Fine-grained authorization, production ownership, operational governance, and future architectural boundaries require confirmation where not implemented.
