# NOTE: source_conversation_id, source_unit_id, source_inbox_id, and
# superseded_by_id are intentionally plain bigints WITHOUT foreign keys.
# Rationale: preserve memory history and audit trail even if the source
# conversation/unit/inbox is hard-deleted (LGPD compliance for customer
# data retention, see spec §10). Application code must tolerate
# dangling references gracefully.

**Observação — FKs secundárias:** `source_conversation_id`, `source_unit_id`, `source_inbox_id` e `superseded_by_id` são `BIGINT` simples sem `FOREIGN KEY`. Manter a referência mesmo após o registro de origem ser hard-deletado é essencial pra auditoria LGPD (§10) e pra relatórios históricos por unidade (§3 decisão 3). App-layer precisa tratar referências órfãs graciosamente.
