Implementations

impl WriteVerdict

pub fn refusal(&self) -> Option<String>

The message an agent reads, or None when it was allowed.

Each names the number that was exceeded, because “write refused” with no figure leaves a model guessing whether to retry smaller or stop - and the retry is what turns one refusal into a loop.
