Decoding: Mismatch report returns the draft token instead of the verified token · case 03

Mismatch report returns the draft token instead of the verified token.

Member previewVariant 3 · 3 implementations · 7 checks per implementation

Case contract

For a nonnegative zero-based rejection index k, return verified[k] when present, otherwise None.

Why this case matters

A self-contained bookkeeping model makes prefix and token-count semantics observable without a model runtime.

One recorded failure
