Coherent three parameter form bounds
ProvedD1Bound5.coherent_three_parameter_form_boundsdiophantine-tuplesnumber-theory
The complete three-anchor interpolation-parameter lemma for the actual coherent form. Exact numerical row checks are separate from the analytic proof; all remainder and branch hypotheses are discharged.
