> In any case according to wikipedia[1] it was constructed between 2022-2024, and "full production" (of cars, presumably) began in October 2024, almost a year ago. By all accounts it wasn't "under construction".

As someone who has worked in IT for a few decades, I have had to go 'into production' with services while things still needed to be, and were still being, built out.

Factories are large and complex: just because one part has been deployed doesn't mean another part has. One simple possibility: they went 'into production' being able to produce X units per week, but work was being done to be able to expand to X+30% units.
