Held-out public-bin fixed-fit score for B23 partial pp branches

ID: solar.detector.b23_pp_recoil_partial_public_fixed_fit

The frozen recoil-aware B23 pp source-plus-detector shift for each independent electron coefficient and detector-sign case is evaluated against the published 2018 total-fit residuals and diagonal errors on the exact public hit axis.

Status: diagnostic

Uncertainty

• This diagnostic badge is a theory locator; its claim still needs independent, claim-specific validation.
