Struct CacheWrite 

pub struct CacheWrite<'a> {
    pub key: &'a str,
    pub fingerprint: &'a str,
    pub json: &'a str,
    pub anchor: Option<&'a str>,
}

The values crate::Store::agent_cache_put writes.

anchor is a node key; the blob stored beside it is captured by the store from the graph at write time, exactly as MemoryWrite’s is, so there is one place that decides what an anchor’s evidence is.

Fields

key: &'a str

The cache key. Content-addressed by the caller; nothing here interprets it.

fingerprint: &'a str

The freshness witness. A reader compares it with the fingerprint the current graph yields and treats a mismatch as a miss — capacity eviction is a separate, orthogonal policy.

json: &'a str

The cached payload.

anchor: Option<&'a str>

The node key this entry is derived from, if any. Supplies the anchor_valid half of the eviction order.
