      "Title": "Extend AKB table DDL tools with declarative unique keys, indexes, and check constraints",
      "Excerpt": "## Background\n\nAKB currently keeps schema changes behind dedicated DDL tools:\n\n- `akb_create_table`\n- `akb_alter_table`\n- `akb_drop_table`\n\nThis boundary should remain. `akb_sql` should stay DML/query-oriented and should not become an arbitrary DDL execution surface.\n\nHowever, the current DDL tools only expose basic column operations. They do not allow callers to define common database-level invariants such as uniqueness, lookup indexes, or simple check constraints. This makes clients implement ",

This issue tracks the remaining **`check_constraints`** (PR 2 of 2) — split out deliberately because it is the raw-SQL-injection-heaviest surface and warrants its own focused review.\n\n## Scope (from #215)\n\nAdd declarative `check_constraints` to `akb_create_table` (create-time) and `akb_alter_table` (`add_check_constraints` / `drop_check_constraints`). **Declarative rule DSL — NOT raw SQL.**",
