The largest per-seed difference is 0.0020 edge, from floating-point noise; seed 10000 gives 443.522608, the same as gates.py. Tuning: 256 seeds from 60000 against base (qm_k1e-5, edge 526.477). Table interpolation RMS was a poor guide: the RMS-best 2-level set {3,7} cost -0.75. The key knot is sd=4 (level 1), not sd=0. Cost curve, best per level count on tuning: 1 level -0.59 (sd 8); 2 levels -0.015 (sd 4,20); 3 levels -0.028 (sd 4,20,34); 4 levels -0.074. Holdout over 10000..12047 vs ref/gauss_qm.json: L15 -0.0098 se 0.0102 and L157 -0.0059 se 0.0101. Both pass. Best is L15: 2 of 8 levels, 268356 cells (4x fewer). Candidates without holdout_paired were not holdout-scored, so passes=false only means not scored; 1-level sets clearly fail on tuning. Byte counts use the brief's 1 byte/cell rule. The expanded files keep unrounded values, so the rounding to whole bps was not tested here. 268k bytes is still far above 32 slots, so this must combine with the knot/mirror/rival-mode items. Next: test L15 with values rounded to 1 bps; try 1 level plus an sd-dependent additive shift (e.g. a per-row spread widen vs sd); combine L15 with row/column knot subsets."}
