Electron LEFT derivative Fourier-orientation audit

ID: electron.matching.left_fourier_orientation_audit

The published right-minus-left derivative definition gives distinct pp, pep, and detector plane-wave momentum factors. A uniform reversal of that definition cannot reconcile the frozen source/detector coefficient-sign triangle.

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.
