Interlanguage CJK Mathematical Notation Backend

Interlanguage CJK Mathematical Notation Backend 1.0.1 is the dedicated, independently citable distribution of the backend first preserved inside the Interlanguage and Mathematical Translation Methodology Sidecar. Read README.md and STANDARD.md first. The shared layer standardizes formula and operator serialization, immutable source and target binding, source-note relations, exact assets, deterministic TeX builds, font and ToUnicode controls, dual extraction, render validation, typed provenance, and supersession metadata. The release includes human-readable rules, machine-readable schemas, 33 evidence records, 16 adverse records, 21 conformance fixtures, a manifest, and a deterministic verifier. This is not a merged CJK language or universal lexicon. Chinese, Japanese, and Korean terminology, grammar, morphology, punctuation, and prose remain independently governed; one language never authorizes another. Positive profiles cover PRC-oriented Simplified Chinese, Japanese, and South-Korean Korean. Other regional profiles remain unsupported unless separately evidenced. The exact 1.0.0 predecessor remains preserved in Interlanguage concept DOI 10.5281/zenodo.21124403, exact version 10.5281/zenodo.21940307. This 1.0.1 distribution does not replace that parent copy. Its implementation registry is empty at release and admits only independently verified static DOI implementations. Produced at Floris's direction. Machine-validated research synthesis; no external, community, native-language, mathematical, or standards-body certification is claimed.
