There's a lot of things that go into a world's TL. Certainly it's starport and population, but other odd factors as well.
Exocet has a Class A Starport is 8000 km in diameter, has a standard tainted atmo, 40% water, a pop of 20, a participatory democracy government, law level of 6 and a TL of 8.
The world lies between Tobia and territories of the powerful Tlaiowaha clan Aslan.
What I derive from all this is this:
- Like as not Exocet's port is run by GeDevCo, probably as an orbital port. The 'population' of the world is most likely the entire staff of that port. While the port can construct starships, it is probably a heavily automated process. This works fine for standard designs, but if you want custom work you're probably gonna need a better port with higher staffing levels. There are good stockpiles of ship parts, so repairs aren't an issue.
- However, the population of the station only has a TL of 8. This means that as soon as their fabricators are out of raw materials to maker up the high speed/low drag stuff, they're back to using wrenches and soldering guns to get anything done.
- What food that is available is either shipped in or grown in hydroponic gardens and carniculture vats. There is very little fresh food available.
- I think that Exocet is a 'tripwire' world for GeDevCo's Aslan containment project. While not a 'garden' world, it has plenty of room to draw ihatei and probably serves as a warning post and trade way station.
- But if the resupply ships ever stop coming, Exocet Station is gonna be in a world of hurt.
