I saw when I removed the clamps that its pretty solid with just the glue.
I tried adding the smallest panel pin I could find (1.4s) - amd the shitty pine started splitting, I drilled .5mm guide holes and opened the tops with a 1.5mm drill bit - filled the holes with wood glue, and slowly hammered in the panel pins.
Pretty confident it'll hopefully be staying put.

2x local handyman I got in (because I'm tired of this sort of ****) - wanted to scrap the door, saying it can't be fixed because of where/how it broke.
What is the cement/filler they put around the glass? You can see a bit of it in the above pic between the decent wood and pine.
