simroot/pure.py: flatlagmempt / flatbandmempt / flatflagmempt - A' with only the flat detector
swapped (Lagouanelle without declining outside (0,1), with memory; Chandrupatla's band; none).
A' itself is untouched: bit-identical to the compiled simbracket on all 868 problems (x2).
sweep_controls.py: K2 through sweep_fourth's harness, K1 with the oracle order m*.
Amendment 1: m* <= 0 is undefined (aps.15.22-30, C0.04 crashed the first full attempt).
Amendment 2 (after the smokes; only corpus-level K1 sums and corpus-4 K2 sums were seen): each
side's slope rounded to 0.01, m* defined only when both sides show a zero (jumps C0.03,
aps.15.21), group 'multiple/fractional' = m* >= 2 or m* <= 2/3, the branches of section 8.1
(simple roots measured at 0.99999 fell under the registered 'm* < 1').
tests/test_article_numbers.py: the verifier test runs on Linux only (the paper's numbers are a
Linux run; libm's last digit differs elsewhere, e.g. 4461 vs 4462).

K1 (point 5): library Chandrupatla and Brent on sign(f)|f|^(1/m*) with the true order m* - an upper
bound for "transform and interpolate". K2 (point 6): A' with only the flat detector swapped -
Lagouanelle with the same memory (hysteresis), Chandrupatla's band, and no detector at all.
Decisive corpus: corpus 4; criteria C1-C5 and what the paper says under every outcome, including
withdrawing the claim that the analogy carries the gain if any control matches A'.
