    You say

    My Stripe webhooks are arriving out of order and occasionally overwriting the 'paid' status with 'pending' from an older event. Please fix the handler in services/payments.ts.

    Your agent does

    I've analyzed services/payments.ts and added a last_event_version check. I modified the database schema to store this version and updated the handler to reject stale events. I also added a test suite to simulate out-of-order delivery.

    What you get

    Prevent stale webhooks from overwriting recent state updatesImplement monotonic state transitions in event consumersAdd sequence gap detection to message queue handlersCreate deterministic tests for reordered message delivery scenarios
