Output stopping: Prompt tokens consume the new-token budget · case 03

Prompt tokens consume the new-token budget.

Member previewVariant 3 · 3 implementations · 6 checks per implementation

Case contract

Given prompt length, generated tokens, and nonnegative maximum new tokens, retain at most that many generated tokens. Return retained list and whether the generated limit was reached.

Why this case matters

A deterministic toy output controller makes one stopping-rule contract independently inspectable.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
