4. A-1 Gate Is Binding

A-1 is accepted as a hard dry-run/pre-execution gate, not as a current defect.

A_1_required_check: cutter_governance.decision_backlog_entry primary key is decision_id uuid
if_mismatch: STOP_and_re_revise_DDL
no_workaround_allowed: true

The dry-run must verify the live parent shape before executing the DDL.
