Will your body burn fat or build muscle if you are dehydrated

When? Physical activity? rest? Be more specific.

In general, assume I only consumed tea / coffee etc for weeks - months with very little water here and there 1-2 cups a day

hydration literally facilitates every single bodily function.

potentially obvious answer: water is the single-most important resource to humans. don't overlook it

don't drink water anything for a couple of weeks then update us

Necessary for general physiological processes but probably not directly related to body mass changes. You will probably develop kidney disease before you notice changes in body comp

Just four days is fine actually.

Tea + Coffee - Water = mad gainz

you got it all worked out bro
