Inspect the actual deliverable [FILE OR OUTPUT] against these checks: [ACCEPTANCE CHECKS]. Use the source inputs to verify facts and completeness. For each check return PASS, FAIL, UNCERTAIN, or NOT RUN, with evidence and the next action. Distinguish content review, file opening, visual inspection, link checks, and executing the underlying workflow. A valid file or successful build alone does not prove usability. Do not claim you saw pages, images, or browser layouts unless you inspected them with supported tools. Identify missing content, incorrect assumptions, broken references, and likely beginner confusion. Prioritize fixes that prevent use. Show what you checked, not just a fresh generic checklist.
