The cap that refuses to report an impossible ISa was zeroing the asymptotic b
itself, and that same value is the floor passed to SigmaWithSystematicFloor -
where zero means "no floor". So on the degenerate low-multiplicity fit the guard
is written for, instead of capping merged I/sigma at 100 it removed the cap
entirely. Report the asymptote as unmeasured, keep the fitted value for the
floor.
