Enum Source 

#[non_exhaustive]
pub enum Source {
    RelationshipWalk,
    CpuSets,
    Description,
}

Which platform API reported something.

Not a trust ordering. Both sources are cheap reads of the running system and neither is more authoritative than the other – where they disagree, D-15 keeps both rather than picking a winner, and D-17 expects genuine disagreement in the field. Trust in the object is Provenance, which is a different question (D-22): where this says who spoke, that says how the collection happened.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RelationshipWalk

GetLogicalProcessorInformationEx – the relationship walk.

CpuSets

GetSystemCpuSetInformation – the CPU-set enumeration.

Description

A description a caller merged in, which named no platform API.

Not what deserialization produces: a restored relation carries no observation at all, because the object’s Provenance already records that it came from a file, and restating it here would duplicate a fact D-22 has just separated. This variant is for the mixed case – a caller adding described relations to a topology that was discovered – which is exactly the case per-relation provenance exists to make visible.
