IRON — Execution Risk Clearance System is a formal clearance protocol that certifies whether an organization is structurally authorized to absorb execution without breakdown. It operates as a pre-execution clearance layer, validating that decision load is distributed, execution pressure is absorbed by systems, operational cadence remains stable under stress, and correction occurs mechanically rather than through escalation. IRON replaces assumption with verification by observing live behavior under constraint and issuing a binding clearance outcome: execution approved, suspended pending correction, or denied. Without clearance, execution does not proceed. With clearance, execution compounds instead of destabilizing the system.
