Formalization Systems I: Number — A Non-Modal Fixation

This paper fixes number within a non-modal structural framework. Number is not treated as quantity, counting, measurement, or arithmetic succession. It is fixed without causality, global temporality, or subject-dependent grounding. The text does not explain number. It delimits the conditions under which formal readable delimitation remains fixed without explanatory equivalence. No subject is introduced. No causality is introduced. No countable totality is assumed.
