Decoding: Target evaluation count omits the rejected token comparison · case 04
Target evaluation count omits the rejected token comparison.
Case contract
If rejection is at zero-based index k, target evaluations equal k+1; if fully accepted, they equal the draft length.
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.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| first rejection | 0 | 1 | Failed |
