Minimal Descriptive Protocol: 0-Band and Slip in a Weakly-Closed System

This note provides a minimal, self-contained descriptive protocol for two operational terms, 0-band and slip, used in the analysis of non-closed systems. It aims to close the terminology at the level of description while leaving the underlying system explicitly non-closed. • Keywords: 0-band; slip; weak closure; non-closed system; descriptive protocol • Notes: Non-evaluative structural audit. No historical positioning. No theoretical comparison. • Audit Tags: • Closure handling: B (Weak-closure) • External viability: Yes • Positioning: Descriptive protocol / Terminological closure
