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: #36 — score 44.3 ● high — all signals present

Coding: #3 — score 66.1 ● medium — one signal missing, weights renormalized

signalweightinput (0–100)
aa_coding 0.30
aider_polyglot 0.30 72.7
swe_bench_verified 0.40 61.1

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

Agentic: #9 — score 61.1 ● low — a single signal; treat with caution
