Interface Topology Typology (ITT) and the Interface Freezing Sequence Table (IFST) A Topology-First Diagnostic Framework for Lock-in Prediction

→ → → CMEM Framework Collection Link This report introduces a topology-first diagnostic framework for predicting irreversible lock-in across biological and engineered systems. It formalizes Interface Topology Typology (ITT), which classifies systems solely by interface count, loop length, latency tolerance, and failure propagation, without invoking function, purpose, or evolution. The Interface Freezing Sequence Table (IFST) is then introduced to model irreversibility as a staged freezing process (ports, rules, loops, logs). The combination of topology type and freezing order predicts distinct lock-in paths and failure modes. A Biological Interface Topology Atlas (12 canonical classes) demonstrates that biological forms occupy the same interface-risk space as engineered systems, governed by identical timing and interface constraints. The core diagnostic principle is: High interface density combined with low latency tolerance leads to non-linear, catastrophic lock-in risk. This document functions as a diagnostic manual rather than a theoretical treatise, intended for rapid structural assessment of stability and irreversibility across scales.
