/**
 * gnubok_categorize_transaction on a transaction that already has a
 * journal entry.
 *
 * categorizeTransactionCore returns a success-shaped object for this case
 * ({ success: true, journal_entry_created: false, journal_entry_error }),
 * which the tool used to pass through as its result. STAGED_OPERATION_SCHEMA
 * requires staged/risk_level/actor/message/preview, so strict clients
 * rejected the structured content and the agent saw only "Structured content
 * does not match the tool's output schema" with the real reason swallowed
 * (feedback seq 288574). The dispatcher's isError path carries no
 * structuredContent, so an Error is the only schema-conformant way out.
