# HXP-007 — Tamper, Transfer and Environmental Qualification

Status: Validation Protocol 0.1

“Tamper-destructive” means that a qualified removal attempt irreversibly breaks NFC continuity, invalidates registered optical fiducials or response, or both. The term is prohibited until the named attachment profile passes its dossier.

The attack matrix covers peel, lift, cut, delamination, solvent, heat, cold, humidity, abrasion, flex, impact, antenna bridging, adhesive replacement, carrier transplantation, optical-window replacement, package reconstruction, and combined slow attacks. A successful undetected transfer is any attack that moves the commissioned identity to a non-enrolled host while all required signals pass.

Environmental work covers service temperature, humidity, UV, cleaning agents, skin oils, sweat, abrasion, bend and torsion, impact, corrosion, dye or plasticizer migration, residue, staining, and optical drift. Profiles are qualified independently; evidence from metal does not qualify leather or artwork.

Certification requires no undetected transfer in the preregistered attack set and complete publication of sample selection, failures, exclusions, and confidence limits.
