It checked the exact statement, its named or normalized variants, recent status evidence, and the controlled TheoremDB corpus.\n\nQueries included:\n- \"ellipsoid fitting\" random points exact threshold 1/4\n- Gaussian centered ellipsoid exact fit d^2/4\n- ill-behaved ellipsoid fit 2025 2026\n\nThe exact formulation, named variants, 2025–2026 updates, and repository-wide semantic duplicates were checked on 2026-08-01.
