Paper 1 — BIFACE-Based Sentence Coordinate Documents: Human-Readable Surfaces and AI+AGI-Referable Coordinates Across Documents, Code, Media, and Conversations

Authors

Abstract

This working paper introduces BIFACE-Based Sentence Coordinate Documents (SCD) as a non-executable structural framework for making human-readable and human-perceivable outputs simultaneously referable by AI+AGI systems. The paper defines SCD/BIFACE as a coordinate-reference structure in which human-readable surfaces and AI+AGI-referable coordinate layers coexist across documents, office-like outputs, code artifacts, image regions, video scenes, subtitles, voice segments, conversational utterances, review artifacts, and revision instructions. The framework does not treat SCD or BIFACE as a storage system, execution system, approval system, consent system, judgment system, legal-effect system, settlement system, evidence-confirmation system, or AI/AGI decision system. It provides a coordinate-reference grammar for later papers in the AGI Structural Alignment Series. This working paper is Paper 1 of the AGI Structural Alignment Series.
