Struct SampleCacheKey 

pub struct SampleCacheKey {
    pub nodes: Arc<[(u32, u32, u8)]>,
    pub reference: (u8, u64),
    pub policies: (u8, u8, u8),
    pub data_len: usize,
    pub time_index_version: u64,
}

Cache key for reusable plans (same request + data/policy version → same rows).

Fields

nodes: Arc<[(u32, u32, u8)]>

Ordered node fingerprints: (variable raw, lag raw, role).

reference: (u8, u64)

Reference policy discriminant + origin.

policies: (u8, u8, u8)

Missing / mask / weight policy discriminants.

data_len: usize

Row count / series length.

time_index_version: u64

Time-index version proxy (0 for tabular; series length for temporal).
