NAIGE NAP 4.0 + A12 Black Box & P-Layer (AP242). One layered schematic: each shell physically contains and constrains the one within, so authority moves outward only through gates — never inward. Rendered with honest evidence-tiering: what is verified, and what remains design-intent.
Mandatory hardware-enforced hold + physical Tiger Key confirmation. Every clinical / actionable decision requires explicit human sign-off. Designed to make agentic drift impossible — FSM hold verified in simulation; physical severance pending bench.
This schematic is the containment map. Its layers are honestly graded against what has actually been demonstrated. The innermost gate — the A12 Core's Sacred Pause FSM — is the one element that has moved from diagram to tested artifact; every other layer remains verified CAD geometry or doctrine, pending the instrumented hardware run.
Tier note: NAP 4.0 / A12 [P+N+D] is the acute robotic stratum (HSA Class C/D); D-layer material remains sovereign-gated for external-facing use. Distinct from the [P+N] Class B residential Hearth.
