signal path of one layer, generated from the registry's structured fields — dimension lines quote the model's real numbers; an MoE trace forks at the router, a dense trace runs straight through. Geometry fields come from the repo's config.json.

# why ranked

Overall: #27 — score 58.2 ● high — all signals present

Coding: provisional — score 45.6 ● low — a single signal; treat with caution

provisional: too few independent signals for a numbered position — the score is shown, but this model sorts after every ranked model.

swe_bench_verified 0.40

missing signals are dropped and the remaining weights renormalized — never imputed.
