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).

(2) The proposed method is again the scheduled projection (2806/3220/6026), its budget multiplier DECLARED as the one free constant: the canonical total is the same for every multiplier 1.25-4, the wide-bracket one is not. The earned projection is the constant-free variant (3568/3020/6588). What the old tables hid: problem by problem the proposed rule beats Chandrupatla on the canonical set 87/24/42, exact sign test p = 9e-5, while trailing him by 0.7% in total; on the wide-bracket set he is genuinely stronger (26 to 9, p = 0.006). Gap decomposition recomputed with the library: 244 (was 262), 160 of it on the flat families (two thirds), fun1 58 (a quarter, not a third as the abstract said).
Also corrected on the way: the 'subsumed by Chandrupatla' pin claimed he is better on the worst single problem - true only with the looser tolerance (84 against the credit rule's 83 once fixed); §8.3 still called zero slack degenerate, which Table 1a refutes; §5.2's Brent figure is our pure-Python implementation and now says so. verify_article.py 286/286, 802 tests pass twice.
