Design — Design QA

Verify the built prototype actually matches the intended design + requirements. Catch drift before it ships. Unlike design-audit (open-ended critique of any UI), QA is a conformance check against a known source of truth — it answers "does this match what we agreed to build?"

When to use

• A prototype is built and you need to confirm it matches the mockup/spec before review.
• Final gate before design-share or dev handoff.
• "Does it match the design?", "conformance check".

When NOT to use

• No spec/reference to compare against → that's open critique → design-audit.
• Nothing built yet → build it first.

Inputs

• The built prototype (local URL or path).
• The source of truth: reference image/mockup, ./design/context.md, ./design/ideate/*.
• Acceptance/success criteria (from context).
