Struct VerdictCtx 

pub struct VerdictCtx<'a> {
    pub goal: &'a str,
    pub criteria: &'a [Criterion],
    pub attempt: u32,
    pub result: &'a str,
}

I3.2 (A2/A3): host-supplied judgment for each attempt’s result. Mirrors the Node SDK VerdictFn. Returning Some(Verdict) short-circuits the built-in LLM eval; returning None defers to it. Sync-only in Rust today — when async hosts need it, lift to a boxed future.
