+-- Expand pending_operations.operation_type to cover op types that were added
+-- in TS (types/index.ts), wired into the risk-tier map and commit dispatcher,
+-- but never added to the DB CHECK constraint:
+--
+--   * create_transaction          — manual transaction ingestion (e.g. Airtable import)
+--   * attach_document_to_transaction — pin a receipt/invoice to a bank transaction
+--
+-- Without this, the MCP tools gnubok_create_transactions and
+-- gnubok_attach_document_to_transaction fail at INSERT with a
+-- check_violation on pending_operations_operation_type_check.
