Core Layer
Structural substrate of boundary positions.
No function. No behaviour. No capability.
Core precedes Surfaces. Positional identity only.
Core Doctrine
Fixed boundary positions.
Components defined by placement only.
No semantics. No causality. No interpretation.
Structural Role
Located between Prime constraints and Surface boundaries.
Positional identity layer.
No transformation. No evaluation.
Component Positions
CAR
Input Boundary position.
Ingress adjacency association.
Boundary-position definition only.
Sentinel
Structural Boundary position.
Invariant adjacency association.
Boundary-position definition only.
CARES
Output Boundary position.
Egress adjacency association.
Boundary-position definition only.
Boundary Conditions
Core positions fixed.
No surface redefinition of Core boundaries.
No artifact occupation of Core positions.
No component implication of behaviour or capability.
Closure
Static positional substrate.
Downstream layers reference fixed boundaries.
“Core is position, not process.”
