A Modular Effective Flavor-Readout Framework for Mass Endpoints, Mixing Overlaps, and CP Residues

A Calibrated Effective Readout Note

抄録

The flavor sector of the Standard Model contains several interconnected structures, including fermion mass hierarchies, quark and lepton mixing matrices, and CP-violating phases. While these quantities are experimentally well established, no unique first-principles framework currently explains their observed numerical patterns.
This work proposes a calibrated effective readout architecture, motivated by the HIPM–AWM–MSL sequence, in which flavor observables are organized into three distinct layers. Mass hierarchies are treated as eigenvalue-based diagnostics, mixing structures are interpreted as measures of relative eigenbasis overlap, and CP-like phenomena are described as residual phase effects associated with loops or basis overlaps.
Within this framework, a central mass-square endpoint variable is introduced as a compact diagnostic of sector hierarchy. A calibrated endpoint relation connects the charged-lepton, quark, and neutrino sectors and yields neutrino-sector endpoints consistent with a low-mass normal-ordering scenario under representative input choices.
The framework also reproduces a characteristic suppression pattern in the CKM sector, supporting the interpretation that non-adjacent quark mixing is structurally reduced relative to adjacent mixing channels. On the lepton side, PMNS and NBLC-related targets are most naturally interpreted as constrained diagnostic endpoints within a normal-ordering, lower-octant region.
The proposal is not intended as a first-principles derivation of the Yukawa sector, the CKM matrix, the PMNS matrix, or CP-violating phases. Rather, it provides a modular effective framework for organizing flavor observables while keeping eigenvalue structure, eigenbasis geometry, and phase information conceptually distinct.
