The Structural Alignment Protocol (SAP) is a discipline for determining whether a cognitive architecture is structurally compatible with a problem. SAP evaluates alignment through invariant detection, layer correctness, architectural coherence, and drift stability. Its purpose is to preserve the generative structure of a problem by ensuring that only aligned architectures remain engaged with it.
SAP functions as an executable protocol rather than a conceptual framework. It operates through a defined sequence of gates—Invariant, Layer, Architecture, and Drift—each of which must be passed for continued participation. The protocol removes misaligned architectures early, stabilizes invariants, and prevents structural distortion caused by layer mismatch or drift induction.
When all remaining architectures are aligned, the system becomes self‑solving: invariants stabilize, drift collapses, and the problem resolves through structural coherence rather than coordination or management. SAP maintains altitude, protects membrane integrity, and provides a universal method for governing high‑level research environments.
