Enum DidDeleteEffect 

pub enum DidDeleteEffect {
    Cascade,
    Blocks,
    Revoke,
    Unrelated,
}

What happens to a keyspace’s DID-keyed contents when that DID is deleted.

Deleting a DID is not one cleanup. It is four different relationships, and treating them alike gets one of them wrong in a way nobody notices until it matters:

• things the DID owns go with it;
• things that name it as a subject of authorization must go with it, or they become authority for an identity that no longer resolves;
• things that depend on it to function must stop the deletion, because cascading would silently break them;
• credentials the VTA issued cannot be deleted at all — copies exist elsewhere — so the only honest action is revocation.

Why this is an enum and not a list in a function

The failure mode is not getting today’s answers wrong. It is a keyspace added next quarter that nobody classifies, whose rows then quietly outlive the DID they belong to. ALL is already pinned by a census test for the backup partition, for exactly the same reason; this rides the same rail, so “we forgot” is a red test rather than an orphan found months later in a log.

The classifications below are judgements and several are arguable. That is fine — the point of the census is to force the question to be asked, not to claim these answers are the last word.

Variants

Cascade

Rows belonging to the DID are removed with it.

Blocks

A row referencing the DID blocks the deletion: something still in use would break. Refused, never forced — the operator is told what to unpick first.

Revoke

Rows cannot be removed, because the VTA is not the only holder. They are revoked instead.

Unrelated

Nothing here is keyed to a DID.
