Marking guide, task briefs, templates, knowledge questions, cross-read together the way an auditor does. Where a task asks for something the guide never assesses, it stops and says so.
Each mismatch names the documents it sits between, so a reader goes straight to the paragraph. The report states what was examined, so the review itself is inspectable.
The next build turns each finding into the fix: what to change, in which document, and why. An assessor still reviews and acts on everything.
Three mismatches account for most of what turns up in a validation meeting.
