# Qwen235B ground-truth audit

Objective: maximum SLO-feasible offered request throughput per GPU.
This report contains real-machine data only; it makes no Frontier match claim.

## Interpretation guardrail

A Frontier top-set hit is insufficient by itself because the surfaces contain large ties. The later comparison must report selected-config regret and tie-aware pairwise ranking, and must keep invalid real cells visible.
