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. This record provides the Expanded Final Publication Edition v3.0 of Paper 1 in the Structural Paper Series under the Research Program on Deterministic Infrastructure and Human-Centered AI Coordination. This version includes unified publication front matter, expanded academic structure, strengthened non-substitution boundaries, and broader cross-domain applicability.
