Moral of the story is ... Pimane is "RAW legal" at TL=4.
A slightly more involved insight would be that the population of Pimane is in a "dieback" condition of slowly withering away rather than continuing to grow and prosper. There isn't much of anything THERE that other star systems are going to want to trade for (at least, by 1105), meaning that Pimane is in the "bust" phase of a Boom & Bust cycle.
Presumably, at some point in the past, there must have been a "rich strike" found that brought people to the Pimane system to "work the mines" and harvest the resources that had been found ... but that resource has been harvested by now, the mines have played out and the boom times are over, so the economics (and thus technology level) of Pimane have been in decline ever since.
If a prospector can find another "motherlode" rich strike somewhere, then the "good times" might come back ... but prospecting is grueling, dangerous work with incredibly low rates of return on investment, so a lot of people have been giving up and getting out of Pimane if and when they can.
Pimane can still probably harvest SOME quantity of resources for sale on the interstellar market (presumably to Strouden), but it's barely enough to keep the world economy going ... and Pimane just isn't "important" enough for some moneybags to come along and try to make a revitalization project out of the place ... so Pimane just keep slowly declining.
Yes, I am aware of the DMs for TL and that for Pimane the TL would be 1D +3, giving a potential RAW range of 4-9; I assume they rolled a "1" during the generation procedure.
The "Minimum TL" I was referring to is from later versions where for different Atmosphere codes they set minimum TL values. In MgT2e, the minimum TL for Vacuum worlds (Atm = 0), it is meant to be 8, but their data for Pimane lists it as TL 7 (presumably to reflect that it is in die-back). Traveller Map and the Wiki, using T5 data also list it as TL 7.
Given the trade factors, it's definitely a case that Pimane is on a "scrape together enough resources out of what is left to sell in order to buy the parts and materials they need to make do and mend, but never enough to pay for everyone to get off the world.
