v0.22.0 — v3+gate default routing
v3+gate is the new default router
The bundled wide-deep classifier now defaults to the v3 checkpoint under a Neyman-Pearson complex gate with a head medium/simple split — the same routing running in Nadir Pro.
v3checkpoint (clean retrain) is the default variant; unlikeasymit keeps a realP(simple).- Complex gate (
complex_gate_v1.pt) decides complex-vs-rest at high recall (τ=0.12). - Head split below the gate beats the legacy companion LR (less under-routing).
- Gate is on by default for
v3, off forasym/symmetric(legacy behaviour intact).
Config (optional): NADIR_COMPLEX_GATE=0 disables the gate · NADIR_GATE_THRESHOLD tunes τ · NADIR_MS_SPLIT=companion reverts the split.
Measured (RouterArena, n=2,479): miss-complex 8.2%, ~41% cost reduction vs always-premium.
NadirClaw's global default classifier stays binary; v3+gate is the default within the wide-deep classifier when selected. See MODEL_CARD.md.
