Struct PromotePolicy 

pub struct PromotePolicy {
    pub enabled: bool,
    pub budget_bytes: u64,
    pub max_node_bytes: u64,
    pub horizon: u64,
    pub rent_per_byte: u64,
    pub min_hits: u32,
}

The pre-registered promotion policy knobs (recorded verbatim in a receipt).

Fields

enabled: bool

Master switch; false (the default) makes the whole layer a no-op.

budget_bytes: u64

Durable store byte budget (promoted output bytes).

max_node_bytes: u64

A bigger output is never promoted (no giant final answers).

horizon: u64

Observation events the governor extrapolates future demand over.

rent_per_byte: u64

Storage rent, work-units per output byte per horizon.

min_hits: u32

Reuse events required before promotion is considered.
