Looks good! Mostly some formatting things. Just lmk if you have opinions/disagree with any!

A few wonky tab formatting things in the lists

[edonehoo]

these guys are refusing to tab in. if this doesn't work, we'll just leave the spacing and manually set the list numbers if needed

Suggested change

	- **Treat AI-generated code as suggestions, not final code.** Review all generated code and modify as appropriate. Thoroughly review and test all code that you intend to integrate into your work.
	- **Do not automatically trust the code assistant output.** Always apply your own judgment and expertise. AI coding assistants can introduce security vulnerabilities if not used carefully, and AI models can sometimes hallucinate and provide incorrect or non-functional code.
	- **Make sure you thoroughly understand any AI-generated code.** If the generated code you intend to incorporate in your work is outside your expertise, consult with someone knowledgeable in the area prior to making it available to others within Red Hat or externally.
