Add two offline standard-library utilities with 30 host tests. Require complete API-covered official-score manifests, finite consistent values and matched denominators; optionally enforce per-case identity. Validate every expected ds4-bench frontier and complete float32 vector, preserving signed zero and reporting drift separately from invalid artifacts.
The existing comparator silently accepts missing rows, duplicate rows and NaN in reproduced controls; the validator rejects them. Saved Flash/Vision 100-case pairs pass unchanged. The frontier tool detects full-vector drift despite matching argmax IDs at all four measured frontiers. Document use and scope without changing inference or introducing model/GPU dependencies.
