E.18:9 - E.18 LEX Discipline (registration)
Register Tech tokens (ASCII) used by this pattern with twin labels: TransformationFlowStructure, TransformationFlowValuation, StructuralReinterpretation, OperationalGate, GateCrossing, CrossingRef, CrossingBundle, GateProfile, GateCheckRef, GateCheckKind, DecisionLog, USM.CompareGuard, USM.LaunchGuard, FlowPositionRef, SubflowRef, FlowEmbed, SentinelId, PathSliceId, SliceRefresh, FinalizeLaunchValues, VALATA. Bridge, BridgeCard, and CL retain their F.9/C.2.1 meanings and are not E.18 crossing tokens. Reference MVPK E.17 naming for faces.
CtxState Extension Registry. Register any extra CtxState slot beyond ⟨L,P,E⃗,D⟩ with: slot id, informal intent, partial‑order rule (with neutral or absorbing), SquareLaw compatibility note, and the Gate profile or profiles allowed to change it. Absence of registration ⇒ non‑conformant.
