Output stopping: Streaming suffix retains only one character of a longer possible stop prefix · case 05
Streaming suffix retains only one character of a longer possible stop prefix.
Case contract
Return (emittable, holdback), withholding the longest suffix of text that equals a proper prefix of any stop string.
Why this case matters
A deterministic output-control model isolates one finish or streaming boundary from any particular runtime.
One recorded failure
