# Expand

Read the current production brief and Frame surfacePlan. Pass guard production, then Hand source implements all requested surfaces using the chosen relationship, exact copy, effective tokens and needed components. A representative concept never replaces full scope. Respect the actual host mode capabilities and exclusive source owner.

After source returns, observer captures each surface's required states x its views and separate declared fixture/state/view stress cases. Use deterministic local data/state recipes, not production API mutation or duplicate normal images relabeled as stress. Fixed captures govern each cell; full-page images supplement continuity.

Run the named native measure/probe/evidence checks. Pixels do not prove tasks or assistive technology. Missing cells/cases remain unassessed; failed stress is a required defect, not research debt. Refresh affected proofs after source changes, then dispatch audit on the complete current evidence.
