Sonus Needle Pathway Shadow

Fine-tuned Cactus Compute Needle checkpoint for Sonus request-scoped pathway tools. The model emits bounded route_NN, slot_NN, confirmation, or stay calls; the Sonus runtime validates every call against the active graph.

This checkpoint is shadow-only. It must not control caller state without an independent acceptance gate and authoritative fallback.

Evaluation

• Independent stress/Noura full-schema gate: 41/77 (53.2%).
• Guard-first, MiniLM top-two request shape: 50/77 local result accuracy.
• High-confidence route acceptance (margin >= 0.15): 27/48 accepted, 27/27 correct on the disjoint gate.
• Local ONNX latency: approximately 254 ms median, 339 ms p95 on the evaluation host.

The full-schema score is not sufficient for authority. The staging deployment keeps Ministral authoritative and records only value-free Needle comparisons.
