# Reality Revision 1.54 — hydrogen spectroscopy gate

The live atom now carries a numerical falsification layer. Four resolved
visible H I Balmer features from the NIST strong-line table are compared with
the exact frequency capacity of the revision-1.53 observer.

For a fixed real five-coordinate skew generator, a linear observation contains
at most two distinct positive frequencies. The four reference features at
410.17400, 434.04620, 486.13615, and 656.28518 nm therefore cannot all be the
linear temporal spectrum of that model. Two free frequencies can fit any
chosen pair, but that is calibration and leaves two features unexplained.
Linear exposure cannot repair the deficit because it changes amplitudes rather
than spectral support.

This is a checked negative result with a useful design consequence. The next
hydrogen engine must declare a different class—most naturally validated energy
state transitions, or else an explicit nonlinear, interacting, time-varying,
or larger-state mechanism—and make fresh predictions. The mismatch is not
identified with a fifth-dimensional string, God, or any unique physical cause.
