Module logit_verify 

Logit / output verification (plan #61).

Borrowed from MAX’s tests/integration/accuracy/verify pattern: every model gets a parity test that diffs RLX’s output vs a reference (HuggingFace transformers, ONNX Runtime, hand-fused, …) using cosine similarity, KL divergence, and absolute tolerance.

Pure data layer — no HF / ORT integration here. Test code calls compare(out, reference, tolerance) and gets back a structured report it can assert! against. Hooking this up to specific reference implementations is per-bench wiring (see burnembed).

Functions

compare

diff + tolerance check. Use this in tests / parity harnesses.

diff

Compute the per-pair diff between out and ref. NaN/inf in either side is a hard fail.
