Module packaging the Route B hypothesis bundle for the Born-rule derivation (paper Proposition 3.7(a)–(d), pre-processed). It introduces a single structure collecting continuity, splitting, and additivity assumptions on a deviation functional, plus elementary consequences for nonnegative reals. Anyone citing the conditional Born-rule route would import this bundle. The file is definitional scaffolding: no deep proofs, only the interface and immediate algebraic lemmas.

claimRoute B collects hypotheses on a real functional $h$ (deviation from the Born weight): $h(0)=0$, $h(1)=0$, continuity of $h$, a splitting identity, and Cauchy additivity $h(x+y)=h(x)+h(y)$ on a suitable domain. From additivity one obtains $h(n\cdot x)=n\,h(x)$ for $n\in\mathbb{N}$, hence $h$ vanishes on the unit interval and on all nonnegative reals under the standing continuity assumption. A companion deviation map $g$ is recorded alongside the bundle.

background

Recognition Science aims to derive the Born rule (squared-modulus probabilities) from cost and recognition axioms rather than postulate it. Route B is one formal path: assume a small list of analytic and algebraic properties of a deviation functional measuring departure from the Born weight, then conclude the deviation is identically zero.

The module sits in the Verification domain and imports only Mathlib plus RS constants (the native tick $\tau_0$). The central object is the hypothesis structure whose fields are the four clauses of Proposition 3.7(a)–(d): normalization at $0$ and $1$, continuity, a splitting law, and additivity. Downstream lemmas record the standard consequences of Cauchy's equation on $\mathbb{R}_{\ge 0}$ once continuity is present: integer homogeneity and vanishing on the nonnegative ray.

No forcing-chain landmark (T5–T8) is invoked here; the file is pure interface for the Born-rule verification branch.

proof idea

This is a definition-and-interface module, not a theorem file. It declares the Route B hypothesis structure, names the individual field projections (normalization, continuity, splitting, additivity), and proves only the immediate arithmetic corollaries of additivity: $h(nx)=n h(x)$ by induction, $h(0)=0$ on the unit, and, with continuity, $h\equiv 0$ on $\mathbb{R}_{\ge 0}$. No external RS lemmas beyond the constants import are required.

why it matters in Recognition Science

The bundle is the pre-processed hypothesis package for paper Proposition 3.7(a)–(d) on the Born-rule Route B. It isolates exactly the analytic assumptions a later uniqueness or vanishing theorem will discharge, keeping the verification layer modular. With no recorded downstream dependents in the current graph, the module is an entry point for any proof that the Born weight is the unique continuous additive solution compatible with the recognition cost. It does not itself close the Born-rule derivation; it only standardizes the hypotheses so that conditional theorems can cite a single structure rather than four loose assumptions.
