Got a call back for a slab I poured in Phoenix last month
The homeowner sent me a picture of a hairline crack running right through the center of their new patio. It was a 12x16 foot pour, and I know I put the control joints in at 8 feet like you're supposed to. Turns out the ground crew had backfilled with some real sandy soil that wasn't compacted right before we poured. I had to go back, cut a new joint along the crack, and fill it with a self-leveling sealant on my own dime. What's your go-to method for checking subgrade before a pour to avoid this mess?

My uncle's patio cracked because he watered the new slab in August heat.

Stomp around on the subgrade like a toddler throwing a fit, that's my high-tech test lol.
