This paper builds, from the indivisible planckon, an account of how composite particles are assembled and how they acquire mass, charge and winding, at theorem level. The method is not reverse engineering: rules come first, the structure they force is derived next, observation referees last; a candidate failing the rules is rejected however close its number. Time is not a dimension but an event counter, and all dynamics uses discrete counter differences; the geometry is cubic with period-two folding. The channel structure consists of three folding axes and one point channel; from this a four-letter alphabet and a three-position reading follow, sixty-four words reduce to twenty content classes, and bond saturation filters these to eight live classes. One rung of the folding sequence turns exactly a quarter turn, four rungs close a full turn, and the order of the sequence leaves an indelible sign. A closed pattern acquires mass, an open one does not; mass follows a discrete spectrum, diameter a single equation. Charge is the integrality of the phase turn around a closed loop, and axis shares generate the one-third unit. Four closure classes — lepton, baryon, meson, condensate — are built with separate equations, each tested against its own report card. That the ledger share of gate crossings is everywhere identical, and only the flank count varies, is bound in one theorem. Finally the framework derives its own boundary: the closedopen dichotomy is incomplete and a third class exists.
