I dont think the builders plaster boarded underneath, though I'm not certain. Likely a skim ot replaster.
The cracks neatly follow the outline of the lintel to the top and where the solid wall stops to the sides . So could be movement in the framing, but why would it start moving after 2 years?
Sliding door is indeed metal, but its to a first floor balcony, so hasnt been opened in months.
Original Lintel was replaced as it wasn't strong enough, you could see all the exterior titles sagging because of it. I did check outside today, and the tiles are still straight , no sag.

Yeah, head scratcher with boring simple potential answers, material with differing rigidity. If there's a skim is of different plasters it's one weakness. The sliding doors & frame appear metal this carries vibration force from opening and closing (not as harsh as plastic) but still a good slam.. as you say it follows the lintel.. why are the cracks formed as if it from plasterboard idk
