Explain how transactions were booked: for each transaction id, the chart-of-accounts account and category it is booked to, whether the account was set on the transaction or inherited from its merchant, who wrote it (USER is a person, AUTO a rule posting without review, ENRICHMENT the AI or a rule awaiting review, IMPORT an import), and the rule that wrote it — set_by_rule_id with the rule's version at the time, or set_by_rule_code for a Lovie platform rule. An empty rule id and code means no rule booked it. Read the rule itself with transaction_get_categorization_rule to see its conditions; it returns the rule's current wording, which may be newer than the version recorded here. Read-only; up to 500 ids per call.
