Example Output
This module acts as the payment reconciliation engine within the billing system. Its primary role is to fetch raw transaction logs from third-party processors, normalize the data formats, and insert them into the ledger database. Developers must note that the processing loop is single-threaded to prevent race conditions during updates; do not introduce multithreading without using locks.
