"Body types don’t match." Since the security cameras used the same calibration standards, it had been easy to include a comparison check in the search. The security system noted feed IDs of known humans and augmented humans (Security officers, Port Authority staff, the merchant crews who did regular runs to Preservation) and I’d used them to annotate my sped-up video. There were only seven unidentified humans who had wandered out of the dock exits during our time frame, none matching the body type estimates the system had taken from the refugees, and all seven unidentified humans had returned via the dock en trance. I matched them on the dockside camera returning to their ships.
