ENGINEERING SCOPE

Clear boundaries.

Custom study application and workflow contributions appear in CharlesDerek history; third-party UI libraries and question content retain their own attribution.

  • Question banks and third-party content are not represented as independently authored certification material.
  • Sign-in and workspace access are handled by the existing services; the portfolio does not share or collect account tokens.
