RET-anchor is the basal layer of the RET framework. Its role is to preserve the position from which a relationship begins, without defining, translating, functionalizing, or moralizing that origin. This document does not explain or reconstruct RET-core. Instead, it establishes a protective boundary that prevents the origin from being rewritten through external interpretation, instrumental use, institutional alignment, or ethical reframing. What is treated here is not behavior, guidance, or theory, but the conditions under which the starting point of a relationship continues to exist as a starting point. Within this perspective, attempts to direct, justify, optimize, or reconceptualize RET-core from the outside are recorded as *cross-boundary actions* rather than as legitimate interpretation. RET-anchor does not expand meaning; it preserves the location at which the relationship originates and ensures that this position is not absorbed into external frameworks. The canonical text of this work is written in Japanese. Any English materials are derivative translations provided for discoverability.Where meanings diverge, the Japanese version takes precedence. Notes────────────────────Canonical Language: Japanese (authoritative). Where semantic divergence occurs, the Japanese text supersedes the English translation.RET-anchor must not be treated as a policy, governance model,alignment framework, or functional specification; doing so constitutes cross-boundary misuse. 正典言語:日本語(優先言語)。 意味上の差異が生じた場合、日本語版を優先する。 本稿を方針・統治モデル・アラインメント枠組・仕様として再解釈することは、越境行為として扱われる。
