1. Production Architecture: Cursor-Based Plaid Transaction Sync, ACH Return Handling & AI Expense Categorization

def sync_plaid_transactions_incremental(client, access_token: str, cursor: str | None) -> tuple[list, str]:
    added, has_more, next_cursor = [], True, cursor
    while has_more:
        resp = client.transactions_sync(access_token=access_token, cursor=next_cursor)
        added.extend(resp["added"])
        has_more = resp["has_more"]
        next_cursor = resp["next_cursor"]
    return added, next_cursor

2. Core Architectural Guarantees

• Idempotent Cursor Pagination: Ingesting bank feed updates reliably via Plaid `/transactions/sync` without duplicate or missed entries.
• NSF & ACH Return Risk Scoring: Checking real-time available balances before initiating ACH debits to prevent R01/R09 return fees.
• AI-Assisted General Ledger Mapping: Automatically matching bank transactions to QuickBooks, Xero, and NetSuite chart-of-accounts.
