Here's an idea: don't proclaim you've finished a feature (apparently in a silo) to leadership and then refuse to deliver it to the code repo.

Like, I totally get it, you used a fancy LLM and it spat out something that looks reasonable at a glance, but aren't sure because your environment wasn't actually set up for local testing (ie never actually run). But still, you could commit whatever garbage was spit out and have someone look at (or, more likely, completely re-write) it, but Nah, puffery is better than delivery I guess.
