Beta-decay mass, charge and spin-sector controls

ID: electron.weak.neutron_beta_mass_sector_controls

Sourced masses allow neutron, pp and pep conversion but forbid free-proton beta-plus decay and both deuteron beta breakups; number-conserving magnetic precession cannot create their final particles.

Status: diagnostic

Uncertainty

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

Claim boundaries

• This badge locates a theory claim; it does not validate a physical effect or engineering application.

Diagnostic context only. Cite independent evidence for claims about the world.
