Structural Principles of Inter-Intelligence Intermediary Syntax (SP-IIIS)

This paper clarifies what should be shared across different Observer Intelligences in Inter-Intelligence Intermediary Syntax (IIIS), and what should remain open to each Observer’s interpretation. EchoScript (ES) is treated as a flat, open-ended shared structure that retains correspondences between references and expressions, allowing different Observers to construct different representations and Interpretations from the same structure. The paper further treats S / O / I not as permanently fixed classes of entities but as roles within observation relations, and formalizes a successive observation sequence in which an ES externalized from one observation can take a new S-role for a subsequent Observer. Aristotle’s ten categories are used as Human-origin default reference axes rather than as a closed ontology. Through a Substance-anchored fold / unfold reading and an engineering example from VATES, the paper presents IIIS as a minimal shared structure that supports plural Observer-appropriate renderings and reinterpretations without fixing a final Interpretation.
