about
nx_dataframe_approx_gate.nx -- THE MEASUREMENT GATE that kills the unmeasured-sketch debt: HLL++ distinct
and t-digest quantiles are graded against EXACT ground truth computed independently in this gate (first-
seen distinct scan; exact sort quantile from nx_dataframe). Deterministic LCG data -> stable, reproducible
error numbers PRINTED (the honest artifact). Anti-false-green: the tolerance checker is proven to FIRE on
a planted wrong estimate. expect_exit: 0 license_tier: ORIGINAL
