01 / THE QUESTION

Editorial guide

Does a frozen radial finite-difference Coulomb model reproduce its exact half-line spectrum, and what can fixed time ticks identify about time?

02 / WHAT THE RECORD SAYS

Source passage

the largest production discrepancy from the half-line reference is $4.7463\times10^{-14}$ Hartree, below the frozen $10^{-8}$ threshold.

03 / LIMITS & OPEN POINTS

Source passage

There are **zero fitted parameters and no measured validation data**. The physical promotion gate remains blocked.

04 / THE NEXT QUESTION

Source passage

The immediate next bounded test is to add the $l=1$ radial sector with its declared centrifugal term and a dipole operator.

05 / CHECKS IN THE RECORD

Editorial guide

This record does not separate a verification section. Read its methods, assumptions and original source before treating a claim as checked.
