The parity-signed octave readout

In the Recognition Science framework, the eight ticks of a cycle each carry a phase posting, and a window (a function assigning a complex number to each tick) records how strongly a posting registers at that tick. The declaration parityOctaveCornerWindow_eq_zero_iff establishes an exact fact about one such window: the parity-signed octave sum, which adds the eight phase windows with alternating signs (plus, minus, plus, minus, and so on around the cycle). The theorem states that this parity-signed sum equals zero at a tick if and only if that tick is tick zero or tick five.

The content is precise and narrow. It does not say the sum is zero at other ticks, nor that it is nonzero everywhere else; it gives the exact two-element set of zeros. The proof, checked by the framework's machine-checked library of formal theorems, works by evaluating the sum at each of the eight ticks and showing that the complex number at tick zero and tick five simplifies to zero, while at each of the other six ticks the number is forced to be nonzero by the algebraic properties of the underlying torus root. The theorem also carries a companion result: the parity-signed sum is nontrivial (not identically zero) and is compatible with the physical photon window condition, meaning it behaves like a legitimate readout rather than a degenerate one.

The significance lies in what the vanishing pattern rules out. The framework's docstring explains that a plain (un-signed) octave sum is nonzero at every tick, so it cannot supply raw support for the two-phase output that the settlement mechanism needs. The parity-signed version is sharper: its zeros at exactly tick zero and tick five mean its support is the other six ticks, the mixed-vertex ones in the Gray-code picture. The theorem therefore proves that neither plain nor parity-signed superposition of single-posting corner readouts produces the desired concentration onto phases zero and one. The residual two-phase output, if it exists, must come from a different settlement mechanism, not from this superposition.

What the declaration does not claim is equally important. It does not assert that the parity-signed sum is the settlement mechanism itself, nor that any physical mass value follows from it. It establishes only the algebraic vanishing pattern of one constructed window. The framework's own description marks the window as a canonical model construction, with no weight chosen to shape the target, and the stated property as a theorem about that construction. The step from this readout pattern to actual mass genesis, the physical bridge, remains open in the framework; the theorem is a necessary condition, not a sufficient one. A reader should take it as a precise structural fact about a defined object, not as a derivation of particle masses.

What this page does not claim

The parity-signed sum is the settlement mechanism itself. Any particle mass value follows from this vanishing pattern. The physical bridge from this readout to mass genesis is established.
