HLV-SM-DOCKING-RECOVERY1 v0.1: Reproducibility Package for a Controlled Standard-Model Recovery Test of the HLV-YUKAWA-BRIDGE1 Effective Scalar Coupling

This repository contains the reproducibility package for HLV-SM-DOCKING-RECOVERY1 v0.1, a controlled decoupling and recovery-limit test associated with the HLV-YUKAWA-BRIDGE1 specification. The purpose of the run is not to derive Standard-Model fermion masses, not to prove the existence of a new scalar mediator, and not to validate the Helix-Light-Vortex (HLV) framework as a complete theory of particle physics. Instead, the run tests a narrower and necessary consistency condition: whether the proposed HLV effective scalar bridge can be formulated as a controlled EFT-like extension that continuously decouples to the Standard Model in the zero-coupling limit. The locked bridge model introduces a dimensionless scaling parameter lambda such that the effective scalar coupling obeys g_chi(lambda)^2 = lambda^2 g_chi,0^2. The numerical scan verifies that for lambda = 0 the HLV scalar correction vanishes exactly, including g_chi^2 = 0 and delta_nu_chi = 0 in the tested proxy observable. The run also confirms the expected quadratic scaling of the correction with lambda, with a log-log scaling exponent of approximately 2 and zero numerical residual against the locked lambda^2 law in the generated scan. The resulting verdict is: PASS_CONTROLLED_EFT_DECOUPLING__SM_RECOVERY_LIMIT_EXACT_IN_LOCKED_BRIDGE_MODEL__NO_MASS_CLAIM This package includes the Python source code, locked configuration, numerical output tables, figures, a PDF report, claim-state ledger, and SHA256 checksums. The result supports only the formal consistency of the HLV-YUKAWA-BRIDGE1 bridge as a decoupling extension with an exact Standard-Model recovery limit in the tested model. It does not constitute evidence for a physical chi mediator, a fit to King-plot data, a derivation of the Standard Model, or an internal HLV mass-generation mechanism.
