At the end of 1910, there must be a complete record of all the traffic in and out of the office until that date. That record can be recorded on some miniaturized computer unit and copied both to every other Patrol office and to Danellian HQ. The record will show that Everard visited the office x number of times. Therefore, it would break the Patrol Prime Directive for him to visit the office an (x + 1) time. The same principle applies to message shuttles sent by Everard. The only exception would be if he were responding to a temporal change that had invalidated the record.
