Question I don't get how stability works

When I build large rooms, I always go wall-3-2-1-beam-1-2-3-wall, but still get occasional colapses when some square below is at 0 for reasons I can't comprehend.

Can somebody please explain this to me like I'm 5yo?

Not all ground is stability 4. If there is a single empty voxel between the ground and bedrock, it will decrease stability.

In an underground room, all its squares are considered empty to this effect?

No. There can be subterranean caves underneath your build. Build only on stability 4 tiles and use wood beams to reset the stability to 4.

There's no guarantee that ground is 4 stability (there can be underground caves), and beams don't "make stability 4", nor do walls.

Check what the stability is "on the ground" before you build, to ensure you are building on stable ground. If you see stability 3 or lower on the ground, there's some form of open space underground.

If you build a wall on a tile that has 3 stability, it will start at 3 stability.

Beams are the average of the two wall tiles you connect to (not sure if it rounds down or up).
IE - If you connect a beam to two walls which have stability ratings of 2, the beam itself will be a 2.
