A.3:6.5 - Reflexive work — scratching oneself
For a work-on-oneself claim, the containing holon is the person, the acting position is the grounded neural-control/right-arm subsystem, and the changed position is the grounded left-hand tissue or state. The exact U.SystemRoleAssignment, applicable method, dated work, work-to-change facts, and A.3.4 occurrence remain separate. Selecting these already grounded subholons uses A.14/C.13; it is not an MHT unless the person as a whole is reidentified under B.2.
