sum_u is a sum of max(0, E^2) over a zone's predicted-absent reflections, in units of their control class's mean, so it is EXACTLY zero when every one of them merged non-positive. The Beta tail then diverges and the clamp that caught it made each such reflection worth about 690 nats. That was harmless while the value only had to clear a bound of 20. Since the absence evidence became the primary sort key, summed across zones with no minimum count per zone, it has ranked the candidates - and it ranked them backwards. A zone of two absences that were never measurable scores 1378 nats where a genuine zone of six absences at 1% of its own row scores 22, so the candidate claiming a screw on an UNMEASURED row beat the one whose rows are actually dead, by sixty times. The comment on the ranking claimed an extra condition "LOSES the zone's evidence when the row is not dead"; an unmeasurable row could not lose, it won outright. No measurement places a merged intensity at exactly zero, so sum_u is floored at a thousandth of the control mean per absent reflection. The constant is an order of magnitude below the precision any real merge reaches - a thousandth of the row mean needs I/sigma ~ 1000 against that row, where ISa tops out near 40 - so it can only remove the singularity, never suppress evidence a measurement could have produced. Measured across the realistic range it changes no genuine zone at all (22.0, 34.7 and 65.4 nats, unchanged to four figures) and takes the unmeasurable ones to 13 and 36, below and around the bound respectively. AbsenceEvidence moves to the header, where the comments already named it, so the ordering it has to satisfy can be tested directly.
