1) Vessels never have to get to the system from outside. There's an interstellar rendevous where those vessels running the 'outer' circuits trans-ship supplies and people to those running the 'inner' circuit.
Friendly amendment: interstellar rendezvouses are a right pain to work out. Some uninhabited, uninteresting star system in the general area will do. (And when the general area is a sphere some 60 LY or more in radius, it's not helpful for a search space.)
2) The people in the "outer" circuit don't know where the planet is, have never seen it or gone there.
3) The people in the inner circuit all have suicide charges on themselves and nuclear demolition charges on their ships. They must return to the system by the appointed time to get the disarm commands or they die. They cannot start talking or they die. They cannot be detained, waylaid or otherwise held up or they die.
Hardcore believers for the crew (or officers at least), a small crew, and possibly GAUL's with the usual sorts of orders can do the trick. Demolition charges on ships are, you know, a safety hazard, and suicide charges in people can go off accidentally too. Mysterious ghost ships and suddenly dying crew mates can throw off operations. They may be able to get away with some alternatives that are a bit less likely to fail badly.
4) The original system can't be discovered via passive observation. There are far too many star systems to check in the given stellar volume to do so in a reasonable time and expense.
Does anyone recall how Darius was discovered? Granted, you can't tell too much about a system from far off, but they've had time to perfect that, time to DO it, and so many systems scouted. I wonder just how they've kept anyone from independently discovering Darius or coming across old records of a potentially habitable system. Sheer luck would go a long way to maintain privacy, but they're not the sorts to rely on it.
