States how the security estate is layered — Taxonomy, Tooling, Engines,
Staff — distinguished by determinism and by the artifact each layer
produces, and what each layer may own.
Carries two normative rules. §5: Staff never touches Tooling directly; it
acts only through Engine APIs — the architectural form of "no privilege
from cognition", and mechanically checkable. §6: access-engine is the only
policy decision point, generalizing to the whole estate the ruling first
drawn in zone-engine/INTENT.md §5, and barring any Staff repository from
hosting a decision point.
Also fixes the vocabulary the estate has used for more than one thing:
access lane vs access rule, doctrine vs runbook, control plane as Engine
vocabulary, and the posture asymmetry.
Owner gate-house, published by net-kingdom. Status proposed: the two
adaptations carrying the most weight — flex-auth's reframing and rename to
access-engine, and kings-guard and ops-warden releasing vocabulary — are
not yet assented by their owners.
