Lock Dynamics in an Anonymous Two-Channel Closed Wave System

Part III of a trilogy. Demonstrates the reality of the quantization mechanism (Arnold tongue, rho = 1/3 exact with width >= 0.92) in an endogenously coupled two-channel system, and completes an elimination program for the order-selection mechanism: measured tongue-width collapse (ratio > 461), fixed-point map elimination, and observational selection with clock inheritance (a J = 8 observer is blind to the order-124 recurrence while J = 248 sees it). The selection problem is transformed into a single falsifiable question: why is the observation clock commensurable with 248? Closes with a survey of the physical-connection problems beyond the trilogy. Japanese and English versions included.
