BY THE TIME WE were on approach to the transit ring, ART had cleared us with the ring’s Port Authority. Shuttles weren’t supposed to be able to dock with transports without advance notice, but ART took care of approach permission, and forged its captain’s feed signature to pay the fine for not giving prior notice of the scheduled trip. They didn’t suspect anything; nobody knew transports could have bots sophisticated enough to fake being human in the feed. I sure hadn’t known it.
