The first pass refined only min(candidates, 4). The comment at the selection already conceded that
the pre-refinement indexed fraction is an unreliable discriminator, and on one dataset degenerate
cells occupied three of those four slots - so the right cell, ranked fifth, was never refined. The
preceding commit's volume guard frees those slots but does not widen them.
This is a one-for-one trade, measured by rebuilding with the old value to confirm the attribution.
It gains one dataset: R_meas 27.2% to 23.8%, with mean I over sigma better in EVERY shell at
identical shell edges, so it is not a resolution ramp. It costs another: a clean abort becomes a
wrong four-fold supercell in P1 at 36% completeness.
That is the same shape of trade already accepted for the plane-normal cap search in the preceding
commit - an honest failure becoming a wrong answer - on a different dataset. It is committed
separately so it can be reverted on its own if the maintainer weighs this instance differently.
