The provided sources do not describe a system called "Circle's Gateway" for settling sub-cent USDC payments. However, the general mechanism for settling sub-cent payments using USDC is described in : nanopayments are settled by signing off-chain authorizations and batching them together, so that many micro-authorizations settle in a single onchain transaction, avoiding per-transaction gas fees. The sources do not mention rounding to the nearest cent or tracking differences in a ledger for reconciliation.
