Design Validation
Answer: does the real implementation express the accepted design and allow the accepted journeys to succeed?
Validation is evidence, not design authority. Do not revise accepted design merely to make implementation pass.
Load the smallest relevant surface skills when platform-specific interaction is materially under test, and load the implementation-focused accessibility-implementation skill when accessibility conformance is materially under test. Those skills provide specialist checks; this skill owns the evidence method and drift judgment.
