...Seriously, there are no interesting and adventuresome circumstancesyou can think of, under any conditions, where a situation like this could ever arise no matter how temporarily? Really?
The UWPs are a snapshot in time, not a prescription of how things have always been and always will be. Some times snapshots capture dynamic, unstable processes in mid-action. ...
In the debate about whether or not to count transients, one issue deserves consideration: who is using the UWP, and for what purpose? Within the milieu, the UWP is issued to serve a purpose. Ergo, whatever rationale we develop for some oddity like Pixie should evolve from the idea that some official process is collecting and distributing this information in order to serve the needs of some body of information-users who need this information.
The UWP is used in part to determine trade. As Rancke points out, "the starport population would still contribute to the system's trade and traffic." Issuing an official UWP that says, "Ain't no one here but this little village," while there's a starport population to serve and make money from, is not serving the interests of those who'll be using that UWP information.
Any small population, irrespective of the port type, is of necessity a dynamic, unstable process in mid-action - a slight change in economic conditions could destroy the place or lead to a major population spike. The real puzzle - if we decide to accept the UWP as accurate and not invoke the "Oh, it's out of date / Oh, they made a mistake" card - is to come up with a workable rationale behind the Imperium telling users of the UWP information that in
this case, there's almost no one here to trade with but there's this major port capable of building and repairing starships (a starport which, by rules, is limited in its construction capacity to the technology level of the world supporting it).
Here, we have the odd image of a high-tech starport
and naval base on a world with too few people to produce the resources it needs to construct ships, much less to staff the port itself or provide the port with any reason for existing. Coming up with a rationale for putting an A-port there and giving it sufficient reason to exist while making the UWP an accurate reflection of the system's trade potential for UWP-users is challenging, to say the least
