- owner_id (FK users, ON DELETE RESTRICT) + index on (owner_id, created_at DESC) - client_id (nullable FK clients, ON DELETE RESTRICT) for client back-references - issuer_snapshot jsonb + snapshot_version: invoices freeze the issuer's legal-entity fields at issue time so historical PDFs render unchanged when the user later edits their profile - voided_at + voided_reason: soft-void instead of delete, since invoices are retained indefinitely - swap unique(number) for unique(owner_id, number): numbers are now per-user, not global DROP CONSTRAINT uses IF EXISTS so the migration is resilient to the auto-generated constraint name differing across Postgres versions.
