Struct ReuseStats 

pub struct ReuseStats {
    pub nodes_executed: u64,
    pub nodes_reused: u64,
    pub cache_bytes_written: u64,
}

Execution accounting for one materialization (ADR-0027). Reuse is claimed by an execution counter, never by wall-clock: nodes_reused > 0 and a smaller nodes_executed are the evidence that persisted work was served from disk.

Fields

nodes_executed: u64

Nodes actually evaluated (cache misses).

nodes_reused: u64

Nodes served whole from the cache (their subtrees were not traversed).

cache_bytes_written: u64

Output bytes written to the cache during this materialization.
