Struct SlotEvidence 

pub struct SlotEvidence {
    pub key: String,
    pub present: bool,
    pub value: Option<Value>,
    pub source: Option<String>,
    pub confidence: Option<f64>,
    pub last_sequence: Option<u64>,
    pub last_origin: Option<StateMutationOrigin>,
}

Provenance and confidence for a single state slot — the evidence behind a value, aggregated from the mutation journal and the state_meta:{key} record.

This is what lets the model confirm principled-ly (“I heard 6, right?”): whether a slot was directly set, resolved from a system, or carries low confidence, and when it last changed.

Fields

key: String

The state key.

present: bool

Whether the key currently has a value.

value: Option<Value>

The current value, if any.

source: Option<String>

Provenance source from state_meta:{key}.source (e.g. agent/fetch/ llm/extraction), if recorded.

confidence: Option<f64>

Confidence from state_meta:{key}.confidence (0.0–1.0), if recorded.

last_sequence: Option<u64>

Journal sequence of the most recent write to this key, if still in the bounded journal window.

last_origin: Option<StateMutationOrigin>

Origin of the most recent recorded write, if known.
