ᐅ Uneven Concrete Slab? Construction Defect?

Hello everyone,
our concrete slab was poured on Friday. For curing, it was initially poured and then covered with plastic sheeting. Due to strong winds on Saturday, the plastic sheeting was blown away, leaving the concrete slab exposed. I cannot see any cracks. However, after heavy rain this morning, puddles have formed, revealing what appears to me to be a significant unevenness (water is standing on one side of the concrete slab while the other side is already dry, despite equal sunlight exposure). I am also attaching a few pictures of the concrete slab. What do you think? Is this unevenness considered a defect? (Picture 1: Sunday afternoon, several hours after the rain; Picture 2: Sunday morning, immediately after the rain; Picture 3: Saturday evening; Picture 4: reinforcement)

So what? That will simply be covered by the screed.

Completely normal.

The screed is what makes it truly "level"

Let's keep things realistic. It's a completely standard concrete slab foundation.

The house will be leaning, and you should neither wear roller skates inside nor let your child ride a ride-on car. RISK OF ACCIDENT due to such a steep slope!
