Delete Domain

Delete all atoms in a domain. Hebbian edges are left untouched.

Tenant-scoped: only deletes atoms in the calling org's scope. Hebbian edges are not swept — see delete_atom above for why there is no such thing as an orphan edge here. Wiping one domain therefore leaves every association learned over other domains' atoms intact.

Secret-atoms (the caller's Vault) are immutable via this endpoint (Design 13): they are filtered out before delete, never wiped, and the count excluded is reported as skipped_secrets.

Like delete_atom, a wipe that breaks supersession chains says so — as superseded_predecessors_left_hidden_count (an int; delete_atom returns the ids themselves, hence the different name for the different shape), because a domain can hold arbitrarily many. A predecessor living INSIDE the wiped domain is deleted alongside its successor and is therefore not "left hidden"; only predecessors in other domains are.
