Enum SupersessionReason 

#[non_exhaustive]
pub enum SupersessionReason {
    NotFound,
    LineageMismatch,
    VersionMismatch,
    AlreadySuperseded,
    CrossRegistrySupersessionUnsupported,
    LineageWalkFailed,
    RevocationTypeMismatch,
    Other,
}

Sub-reason for AcdpError::SupersededTarget. Starts from the details.reason values enumerated by acdp-error.schema.json’s superseded_target description (not_found, lineage_mismatch, version_mismatch, already_superseded, cross_registry_supersession_unsupported) and adds typed reasons this library recognizes beyond what that enum currently lists (LineageWalkFailed, RevocationTypeMismatch) — it is a superset, not a mirror. #[non_exhaustive] plus the Other catch-all below is what keeps a schema addition from being a breaking change here.

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.

NotFound

The supersedes target context does not exist on this registry.

LineageMismatch

The target’s lineage_id differs from the new publication’s lineage.

VersionMismatch

The new version is not exactly previous.version + 1.

AlreadySuperseded

The target has already been superseded by a different version.

CrossRegistrySupersessionUnsupported

The target lives on a different registry; v0.1.0 only allows same-registry supersession.

LineageWalkFailed

The lineage walk through supersedes failed because an intermediate context could not be retrieved (RFC-ACDP-0001 §5.6.1).

RevocationTypeMismatch

A non-revocation context superseded a key-revocation (or interim acdp:key-revocation) target (RFC-ACDP-0014 §4/§10). Only emitted by registries advertising acdp_version >= 0.5.0; below that version this rejection surfaces as AcdpError::SchemaViolation instead. Provisional per registries/error-codes.md (the 0.5.0 line is still Draft).

Other

A reason this version of the library does not recognize.
