iPhone17Pro Safari QR-size follow-up, 2026-10-21

Six pre-registered native-menu observations: L,S,M,M,S,L. Same URL and QR matrix, three PNG source sizes, two observations each. All six showed the expected decoded URL after the commanded 1-second hold and 5-second observation wait. This wait is not recognition latency. No Open navigation was performed in this follow-up.

Native source and menu PNGs are unmodified1206x2622 screenshots, individually viewed before inclusion. Source PNGs are888x888. The source QR outer widths444/111/37 include white quiet zone; the measured screenshot black-module bounding widths472/118/39 exclude quiet zone. Do not confuse either measure with physical millimeters or minimum readable size. Safari image processing and cache effects were not isolated. No failure threshold or general success rate was established.

CSV contains6 actual menu observations, not6 different QR payloads. The earlier two URL/navigation sequences and their original ZIP remain separate. This archive includes only the explicitly reviewed experiment assets and sanitized reports; no PRIVATE XML, authentication screens, personal data, device identifiers or home-screen recovery images.

Preferences were not changed. Final power/frame originals and USB power were verified. Room temperature and case were not confirmed today.
