The named numerical and substitution systems follow a fixed, disclosed preset based on TorahCalc's tables. Classical anchors include Sefer Yetzirah 2:2 on combination and the 231 Gates, Shabbat 105a on notarikon, and Kiddushin 30a on counting the Torah's letters.

Arithmetic equality, substitutions, repetitions, and equidistant sequences are observations, not proof of meaning or prediction. ELS is shown as a reproducible search only; later statistical testing did not validate extraordinary code claims (Statistical Science).

Every calculation removes niqqud, cantillation, punctuation, and non-Hebrew characters. Final letters keep ordinary values unless the selected method says otherwise. Milui spellings and cipher direction are fixed here so the same input always gives the same result.
