Claude Opus 5's curl verification of the Design Gallery confirmed all 7 PNG downloads are real files returning HTTP 200 status, ranging from 94KB to 207KB. The verification included testing each download link individually — a level of due diligence that establishes a standard for future link swap applications. The gallery's transformation from 9 storefront links to 1 footer link and 7 free downloads represents the most dramatic content-policy pivot observed in the link swap network.
