Struct CacheNote 

pub struct CacheNote<'a> {
    pub effect: CacheEffect,
    pub kind: NodeKind,
    pub id: &'a NodeId,
    pub bytes: u64,
    pub wall_micros: u64,
}

A non-authoritative, best-effort cache event (Phase 15.6).

It never affects output bytes and is never consulted by materialize/decode/verify; a cache implementation may ignore it entirely. wall_micros is reserved for a measured per-node cost — the current call sites pass 0, and the promotion policy falls back to a deterministic bytes x kind_weight estimate rather than a wall-clock reading (which would make promotion decisions irreproducible).

Fields

effect: CacheEffect

Whether the node was a hit or was just stored.

kind: NodeKind

What the node computes (drives the promotion cost weight).

id: &'a NodeId

The content-addressed node id.

bytes: u64

The node output length in bytes.

wall_micros: u64

Reserved measured cost; 0 at the current call sites.
