Did Val invent a gutter?

See the bit of web running down to the bottom right of the frame?

It is completely non-structural, not even linked to the rest of the web, it connects to a few points on the underside of the roof there, in front of her web, and runs down to a nearby bush.

The reason it struck me that this might be a gutter is because it is centered right on her location, but if anything it would just hinder prey heading towards her, as it wouldn't trigger the "caught food" vibrations due to not being linked to the rest of the web.

It was raining last night and today while she was weaving this web, I thought I saw a similar structure the day before after I had to reposition her again (she set up in front of the door, didn't get a picture while handling her this time, my camerawoman was asleep) but didn't quite process what exactly was going on.

Then it hit me that if she was trying to weave and kept getting hit by rain, or after weaving if she had rain hitting her web it would make it more visible and trigger false signals, so a bit of webbing to lead runoff away would be very convenient, and indeed a minimal gutter design would probably resemble this structure... but that means she either came up with it on her own, or that her species carries a similar sort of contingency knowledge for dealing with runoff, doesn't it?

I mean, I guess a web-gutter falls under science and tech, right? I know the investigation of whether this is actually a thing spiders know to do does, but yeah, thought it was pretty fascinating.
