groundTruthCoverage reads the ground-truth facet alone and reports how many queries have all k neighbors, how many have none, and the recall@k ceiling a perfect search would score. requireAttainableRecall refuses a run below a threshold before a million rows are loaded for a number that could never be read, naming the ceiling and the profiles that would read. On tessera, 100k mixed ceils at 0.1428, 300k-uniform-2-1e-3 at 0.988, and 1m-uniform-2-1e-3 at 1.0.
