Decoding: Rejection location is reported as a one-based position · case 04
Rejection location is reported as a one-based position.
Case contract
Return the zero-based index of the first differing token, or the number of compared tokens when all compared pairs match.
Why this case matters
A self-contained bookkeeping model makes prefix and token-count semantics observable without a model runtime.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
