leonarski_fandClaude Opus 5 a452797ce5 rugnux: the short-axis pass checks the premise it was built on
The pass exists because a lattice row shorter than the standard search floor is reported at
its first harmonic above it, so a cell it may rightfully adopt has a reduced axis below that
floor. It never checked that. Where the alternative has no axis under the floor, the floor
cannot be what the standard pass tripped over, and the integer volume ratio is an ordinary
axis multiple - the question the axis-harmonic arbiter settles a few lines above, on the
occupancy of the class the multiple adds. That is evidence about the reflections in dispute,
where the tie this pass reads is a frame count a sublattice cannot lose; where the two
disagree the arbiter is right, and this block was overruling it.

Two crystals were being halved on that account. Both keep their cells now, and the small
molecules the pass was written for are untouched: their reduced axes are all under the floor,
which is the premise holding.

The environment variable that held the pass off is gone with it. It was there to diagnose
exactly this, and a check in the code is the better answer than a switch nobody sets.
