/**
 * RASHOMON SET (EQUIFINALITY) — you don't have one best recipe, you have a FAMILY. Optimization hands back
 * a single winner, but reality is kinder than that: there are often several genuinely different settings
 * that all score within a hair of the best. That hidden freedom is worth money — among equally-good
 * recipes you can pick the cheapest to run, the safest, the one using materials you already have, the one
 * far from a cliff. A tool that only ever shows you ONE answer throws that choice away.
 *
 * RASHOMON gathers every measurement within a small tolerance of your best, then clusters them into
 * genuinely DISTINCT recipes (not ten copies of the same point). It reports the family: how many real
 * alternatives you have and what they are — so the decision becomes yours, not the optimizer's.
 *
 * Named for the Rashomon set in machine learning (the set of near-equally-good models) and equifinality in
 * systems science (many paths, same end). Honest by construction (DIAKRISIS): every recipe returned is a
 * REAL measurement of yours within the stated tolerance of the best — not an interpolated guess; "distinct"
 * means separated in the normalised variable space. It abstains on thin data and reports just the one
 * winner when the near-optimal points really are all the same place.
