Phase cancellation in the path sum

In Recognition Science, the ledger, a discrete record of recognition events, can be organized as a path sum over triangulations of a space. The central object here is Zq, a sum over equivalence classes of these triangulations, where each class is weighted by a measure and, in this setting, by an oscillatory phase. The classical problem this addresses is that such sums can be large or ill-defined; the purpose here is to show, under a fixed complexity cap, that phases can be introduced to make the sum smaller and better behaved.

A set of structure theorems is established. For any phase model, a real phase function on labeled configurations that is invariant under relabeling, the phased Zq is a finite sum with a proved bound: its norm is at most the total mass of all classes, which is at most the number of classes. This is the boundedness result. More importantly, if one can pair classes with exactly opposite contributions, then the paired terms cancel exactly and the bound improves strictly, beating the triangle inequality. This is a general statement about finite sums under a stated hypothesis; the cancellation mechanism itself is supplied by the hypothesis, not derived.

A concrete witness is provided at complexity cap B = 2. An explicit phase model is defined: phase 0 on the empty complex, phase π on the one-point complex. These two classes have equal mass and opposite phases, so their contributions cancel. The proved chain shows the norm of the phased sum is at most total mass minus 2, which is strictly less than total mass. This demonstrates that the pairing hypotheses are satisfiable, not vacuous.

In Recognition Science, this is a step toward a larger goal. The zero-phase route to removing a regulator is dead, so any well-defined removal needs phase cancellation. The results here provide proved cancellation mechanisms at a fixed cap only. The continuum limit of the phased Zq remains open, as does regulator removal at any oscillatory phase and a substrate-derived phase function. The status is a theorem for the structure at fixed cap, a model for the phase shape, and open for the limit.

/-- **THEOREM (well-definedness of the phased Zq at fixed cap).**  For
every phase model, the phased quotient-first path sum has unit-modulus
weights and satisfies the proved finiteness bounds.  This is a structure
theorem at fixed complexity cap, NOT a continuum-limit statement. -/

What this page does not claim

The continuum limit of the phased Zq is not proved here. Regulator removal at any oscillatory phase is not derived. A substrate-derived phase function is not provided. The cancellation mechanism is not derived; it is supplied by the pairing hypothesis.
