Enum Compatibility 

pub enum Compatibility {
    Identical,
    Superset,
    DestructiveSuperset,
    Subset,
    Divergent,
}

Result of comparing two ontologies for sync compatibility.

Variants

Identical

Same resolved ontology (identical hash).

Superset

Local contains everything remote has, plus more, and nothing the remote already holds stops validating. Safe to merge.

DestructiveSuperset

Local is a superset on the declarations, but the extra facts include a requirement the remote’s data was never held to. Adopting this ontology would quarantine entries the remote considers valid.

This is reported instead of Superset so a consumer that gates an automatic migration on "superset" falls through to its refuse branch rather than migrating into data loss.

Subset

Remote has types/properties local doesn’t have yet. ExtendOntology entries in the sync payload will resolve the gap.

Divergent

Neither is a superset. Incompatible fork, cannot be resolved by additive evolution alone.
