ᐅ Cracks in the Screed: Are They a Problem?

Hello,

We have the final inspection of our house next week. Today, we thoroughly examined the house and noticed that long cracks have appeared in the screed on the ground floor. Also, the corners at the patio doors are rounded.
The builder says these are normal stress cracks and nothing to worry about.
Do these cracks necessarily need to be repaired? What happens if we simply lay our vinyl flooring over them now?

Also, does anyone know what these 'cables' (last picture) in the screed are?
Thank you in advance

Regarding the cables, what is installed where the cable comes out? That's probably what it is for.
I don’t see any cracks; it looks more like a decoupling mat inside that is visible for some reason.
As for the corners, not ideal but basically not problematic.
You will definitely need to apply a leveling compound under your vinyl flooring.

Nothing will go there anymore. Only the floor will be laid over it. These cables are also present in other rooms.

I don’t see any cracks either. Could it be that "the cable" is somehow used for moisture measurement? The corner doesn’t look nice to us, but the screed installer would say, "Perfectly filled. Tiles or parquet flooring over it, and it will be fine."

Thanks in advance, I hadn’t even thought about the decoupling mat.
The cracks are easier to see in these pictures.
The question is whether these cracks definitely need to be repaired.

Since the uncoupling mat is probably laid there, I would say it is normal for the screed to develop a crack in that area.
