RNA--RNB Coupling: A Non-Redundant Dual-Chain Runtime Model

CMEM Framework Collection Link This report proposes a dual-chain interface model integrating CMEM and NIRM through an explicit separation between generative structures and release dynamics. The framework formalizes two non-isomorphic but coupled chains: RNA, representing generative alphabets and state expansion (AGCTU), and RNB, representing non-intentional release, arbitration, and return-path control (ATRDC / ATRDCA′). Unlike DNA-like inheritance models, this work operates strictly at runtime. It analyzes how systems retain or lose continuation capacity after release, without invoking intention, optimization, teleology, or narrative closure. The model is applicable across biological, cognitive, civilizational, and interface-engineering domains, providing a diagnostic methodology for identifying lock-in, noise amplification, and return-path collapse. This document functions as an interface-level diagnostic report, not a theory of origin, meaning, or purpose. CMEM–RNB Relationship (Structural Clarification) CMEM and RNB do not constitute models, theories, or predictive frameworks. They describe system operating order, not representations of a system. CMEM provides a minimal perceptual projection of system coherence. Its DEG notation (Decoder–Echo–Debugger) is not a structural decomposition, but a human-readable abstraction used to indicate whether a system remains intelligible, referencable, and internally consistent. The triangular form of CMEM does not encode causality, hierarchy, or flow. It is a visibility constraint, not an architectural diagram. RNB does not extend CMEM into a more detailed model. Instead, it expresses the same operating order under runtime conditions. Where CMEM marks whether coherence exists, RNB records how coherence is released, redistributed, and re-entered over time. The RNB cycle (often rendered as AGCTUA′) is not a sequence of steps, but a closed operating loop that admits interruption, re-entry, and asymmetry without collapse. It describes persistence under pressure, not optimization or control. The relationship between CMEM and RNB is therefore not hierarchical or compositional. They are two projections of the same system order: • CMEM describes structural legibility (whether a system can still be read). • RNB describes runtime continuity (whether a system can still proceed). Neither framework simulates, predicts, or replaces the system it describes. They do not function as models. They record how systems remain systems, not how systems should behave, evolve, or be engineered. Author’s Note I did not write these documents to explain the world, nor to correct existing theories, propose alternatives, or compete for coherence. These texts exist because, in many domains, explanation continues long after the interface has already failed. CMEM and its associated notes are not theories, models, or predictive systems. They are diagnostic records—written at the moment where interpretation should stop, but usually does not. I am not interested in answering “why” questions once structural admissibility has been lost. I am interested in identifying where systems cease to be interpretable, where optimization becomes noise, and where continuity is falsely assumed. Many of the expressions, symbols, and constructions used across these papers are intentionally non-operational. They are not unfinished formulas. They are finished boundaries. If a reader finds themselves trying to compute, extend, refute, or apply them, then the boundary has already been crossed—and the document has done its job. These writings do not ask to be believed. They ask only to be placed correctly. I make no claim that these documents are necessary. Only that they are precise. If they are useful, it is because a similar interface failure has already been encountered. If they are not, they may be safely ignored. Nothing here instructs action. Nothing here predicts outcomes. Nothing here promises understanding. They simply record where understanding ends. — 陈偌桐 Chen Ruotong 知所先后,则近道矣。
