A cup tastes balanced and sweet for the first few sips, then sharp and astringent as it cools. I've noticed this more with a light roast brewed as pour-over. Maybe the lower temperature reveals flavors that were masked when it was hot, or maybe my extraction is off and I only notice later. Do you deliberately taste a brew at several temperatures when adjusting a recipe? I'd like to make a cup that's pleasant beyond its first five minutes.

Yes, taste it as it cools. Hot can hide a lot, and some cups only show the rough edges once they drop below “burn your tongue” temperature.

Astringency often shows up more clearly when the cup cools. If it’s sweet at first and then gets sharp, I’d suspect the brew is a little too extracted.
I’ve also noticed light roasts do this more. They can go from bright to pinched pretty fast if the grind or contact time is a bit off.
