Enum ResidentGraphCacheMissReason 

pub enum ResidentGraphCacheMissReason {
    EmptyCache,
    DomainChanged,
    BackendChanged,
    LayoutChanged,
    ShapeChanged,
    KeyAbsent,
}

Backend-neutral resident cache-miss reason for diagnostics and release evidence.

Variants

EmptyCache

The resident graph cache has no entries.

DomainChanged

Entries exist but for a different resident graph domain.

BackendChanged

The same domain exists but backend id or backend version changed.

LayoutChanged

Domain and backend match, but the graph layout/content hash changed.

ShapeChanged

Domain, backend, and layout hash matched, but shape fields differ.

KeyAbsent

Adjacent identity says the entry should exist, but the final key missed.
