+-- Postgres schema for the scoble_policy_audit log.
+-- Mirrors the audit shape that OPA produces.
+-- Time-partitioned (assumes pg_partman or a manual monthly partition
+-- rotation script; for personal-cluster scale a single table is fine).
+--
+-- MIGRATION NOTE (2026-06-07): the previous table (with a decision_id/actor/action/
+-- resource/verdict/metadata shape) was dropped and replaced with this shape.
+-- The audit-sink Integration (audit-sink-integration.yaml) has always targeted
+-- this shape (agent_id/kamelet_ref/decision/reasons/rule_id/request_id).
+-- Run as the `postgres` superuser or a role that owns the table.
