Default deny. Nothing in the process is trusted until each control is verified with evidence. Tick a control only when you hold the evidence for it.
Each reconciles a figure in the summary. A failed check means the figure is not supported and cannot be trusted as written.
Each item must be closed with evidence before any commitment.
Principles applied: verify explicitly, use least privilege, assume breach, and verify continuously. Checks run in this page only. Nothing is stored or sent.
