Two high-contrast lines, right angles. In a visual cortex running approximately three times baseline myelination, the vertical edge and the horizontal edge arrive at the same neurons together. Constructive interference. Geometric epilepsy, documented in HHDRV Chapter 21. The present appendix only catalogues the artefacts that exploit it. Latin, Lorraine, Patriarchal, Orthodox with the slanted suppedaneum, Greek, Templar pattée: additional beams are additional axes. The religious history is secondary culture on an optical fact.

Pendant format is operationally marginal: angular subtense at engagement range is too small. Plate, shield, door, banner. Raise the cross is a size instruction. Ineffective on LCAN, Vigilans, and baseline — they do not have that cortex. Seizure, not faith.
