Model steps judged after a re-fit of the weights, 2026-10-04

From reports/tiers/2026-10-04-refit-killclass.md , rendered when the site is built.

Each run: tools/ledgerfit.js fits the base (every step switch off) and fits again with the run's switches on, by the same procedure: the seven weights and lands fitted, everything else hibernated at tools/ledger-benchmarks/2026-10-03-step6-baseline.json; ridge λ 0.01 toward the base benchmark's values; the same seeds. Lists: tyr.auspex, tyr.hivemind, tyr.second, tyr.maelstrom, tyr.astrategas, sm.auspexFull, sm.tobias. Yardstick through compute() at each fit (ρ; pairwise on the tiers S to D, as the step log). Leave one list out: each list scored by the fit on the other 6. Noise: each army's SD of mean ρ over the scrambled fits (10 per ledger, the base's and the run's pooled: 20). Hint by the keep rule: KEEP only when the mean ρ and mean pairwise both rise and neither army's mean ρ falls past its noise. A hint; the supervisor decides.

The base row compares the step-6 baseline as it stands (its weights, unfitted; left out is in sample there) with the base re-fitted on the 7 lists. Noise (SD of mean ρ, scrambled fits): Tyranids 0.038, Space Marines 0.107, all lists 0.038 (first run's pool).
