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: provisional — score 63.9 ● 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.
| signal | weight | input (0–100) |
|---|---|---|
| aa_intelligence | 0.70 | 63.9 |
| bench_composite | 0.30 | — |
missing signals are dropped and the remaining weights renormalized — never imputed.
Coding: provisional — score 52.6 ● low — a single signal; treat with caution

# trend
methodology changed during this history window; score movement across that boundary is not model movement. See methodology v5.
