Maybe a service mentality would help you make that bearable for as long as it still lasts? For my consulting clients, I make sure I inform them of risks, problems and tradeoffs the best way I can. But if they want to go ahead against my recommendation - so be it, their call. A lot of technical decisions are actually business decisions in disguise. All I can do is consult them otherwise and perhaps get them to put a proverbial canary in the coal mine: Some KPI to watch or something that otherwise alerts them that the thing I feared would happen did happen. And perhaps a rough mitigation strategy, so we agree ahead of time on how to handle that.

But I haven't dealt with anyone sending me vibe code to "just deploy", that must be frustrating. I'm not sure how I'd handle that. Perhaps I would try to isolate it and get them to own it completely, if feasible. They're only going to learn if they have a feedback loop, if stuff that goes wrong ends up back on their desk, instead of yours. The perceived benefit for them is that they don't have to deal with pesky developers getting in the way.
