A block read repeats one 32 bit word, so every offset yields a rotation and more than one can pass the structural checks. A T5577 in direct/nrz carried both 00080040, the word on the tag, and 00080001, its ror19 - both master key 0, reserved 0, RF/32, direct. test() answers with the first hit from a fixed floor, so which one detect reported was scan order rather than evidence. No structural check separates them: every bit of block 0 is a real field, and the three the scan skips are otp, fast write and inverse data, all settable. The tag can, though - maxblock has to account for what regular read mode cycles through. So measure the broadcast period and keep the rotation that agrees, reusing the constraint printConfiguration already applies to the psk2/psk3 pre-images. Costs one acquisition, and only when the reading is ambiguous. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
