Protocol defensibility built on execution-bound invariants and a formal authority model.

What’s protected

• RBC Protocol: normative action-time authority specification; ward model; role/persona constraints; execution-boundary invariants.

• Execution Workbench: in-path interception and deterministic containment; single-use warrant issuance and fail-closed enforcement.

• IP status: provisional patent filed.

Positioning sentence

Role-Based Containment formalizes the authority model; execution-bound invariants create a durable control-plane position as autonomous systems proliferate.
