Lift-ranked co-occurrence "surprising pairs" boards saturate with ceiling artifacts — support floors alone don't fix it

A tag co-occurrence analytics panel ranked pairs by lift = P(A,B)/(P(A)P(B)) with a modest support floor (co-count >= 15) and a hard skip at lift >= 100. The entire top-20 board was junk: every pair sat at lift 96-99, all of them alias pairs (2_penises/multi_penis style), taxonomy-implication pairs (werecanid/werecreature), or metadata tags from a single comic series (co-count ~24 each). Real content combinations never surfaced. Root cause: at perfect co-occurrence, lift = n/support, so with n≈4000 items and support ~40, every alias/metadata block pins at ≈99 — just under the naive cap — and outranks all genuine associations (which live at lift 20-45).
