the stain might end at the level of the original floor which may have been several inches higher than the currently exposed floor.
Wouldn't we expect a hard line if this were the case?
Here are a few more images showing different drip patterns. Any idea why the drips keep changing? These are what I'd expect a trickle to look like though- in the other images the stain is the entire width of the opening. In these ones it follows the seam.
