The Mechanical Priority of Being

Plate XXV defines the mechanical containment topology of the Standing State. Identity occupies the stationary coordinate (Axial Lock: V = 0); load does not move I*. The Hybrid Containment Protocol (HCP) governs lawful dissipation through four operating principles: hex-cell compartmentalization isolates entropy into discrete cells so local failure does not propagate; boundary integrity closes the domain against cascade coupling; black-body dissipation radiates high-energy stimulus outward without internalization; axis supremacy permits orientation change while identity displacement remains zero. The Six-Vector Phase-Lock — Work, Family, Body, Money, Mission, Rest — synchronizes operational domains as oscillatory vectors phase-locked to the invariant identity coordinate; stress registers as phase-jitter rather than identity corruption; phase-reset returns the system to baseline so ∫V dt = 0 holds at the identity level. NSRL-11 formalizes edge-case containment: zero-vector response, hard boundary lockdown, and auto-ablative shell investment that allows the public layer to char while the invariant core remains intact. Pruning is admissible: selective reduction, controlled dissipation, coupling removal — not identity reduction. The shell may invest. The boundary may prune. The axis does not move.
