BaZi Is Not Astrology: The 3-Letter Protocol (3LP) and a Standardized Nomenclature for Baziologics

This technical note proposes the 3-Letter Protocol (3LP), a fixed-width, ASCII-based code system for English-language BaZi research. 3LP provides zero-ambiguity, human-readable, and machine-parsable representations for all BaZi fundamental entities: 10 Heavenly Stems, 12 Earthly Branches, and 10 Aspects (Ten Gods). The system is the first formally specified component of BaZi Infra — a foundational infrastructure layer for the emerging field of Baziologics. The paper also clarifies that BaZi is a temporal operator system, not a form of astrology.
