 veto providers. Modules that own tenant-scoped data must contribute summaries
 so destructive deletion cannot silently miss their rows.
 
+Delete veto providers are registered through module manifests and receive
+`(session, tenant_id, resource_id)`. Providers should return a structured
+`DeleteVetoIssue`, a list of issues, or `None`; legacy providers that raise an
+exception are treated as blocking module vetoes. Tenancy exposes those issues in
+the deletion plan with module attribution and resource details, so operators can
+see which module blocks or qualifies the lifecycle action.
