I didn’t think it was a match for Alternaria either, pretty close, but these are very light surface scars. I did have some tomatoes crack in addition to the cracking in the photo. Thanks! I’ll treat the plants for stink bugs and keep my fingers crossed.

The staining may only be happening in a few boards but the CUPPING of the planks is more wide spread. That's the biggest issue. As for moisture mitigation during install, it would be up to you to contact the original installer to find out what was done. Only they can answer those questions for you. But I will give you a heads up on that one. These OLD slabs (1948 = post war era building boom) are often thought of as DRY when carpet is removed (again, this is why I asked what USED to be on the floor). The slab will 'test' as dry because it has been happily evaporating off moisture THROUGH the carpet for decades. And decades. And decades. Many moisture tests (ie. anhydrous calcium chloride test) will see how much PRESSURE is in the slab on that day. If carpet is removed and there is NO BUILD-UP of moisture/pressure BEFORE that day, it will 'read' as a nice dry-ish slab. Once the slab is CAPPED (solid flooring put over top = nowhere for the water to escape = HIGH moisture content/pressure) it gets MUCH more difficult to deal with. If you test the slab TODAY it will be MUCH HIGHER than the slab was before you put the wood on it. The moisture barrier treatment at the TIME was 'good enough' for the reading (3 years ago before the slab filled with water). But NOW the moisture has overwhelmed the system used. This is why it takes wet-basement specialists to figure out some of these old slabs. The moisture tests done before they were capped probably looked very good (or very promising to be good in the future) but the wood flooring people could not predict the pressure build up over 3 years. That's not their level of expertise. A wet-slab/basement specialist *MIGHT have been able to guestimate the issues...but they too might have guessed wrong. These old slabs are SUPER TRICKY to predict. Please tell us if your floors are glued down to the concrete or if they are floating. Please add more photos of the cupping please. Tell us how much of the 1800sf is having moisture issues (cupping/staining, popping, etc).

Any ideas as to these colors? Looks like 2 different ones and I love them both. We have the same shakes on the top.

A sconce over the window - brass to match the hardware. Possibly black and brass together. I am not sure if it would be too heavy with the black hood but it’s something to consider. And see if you can find a sconce that compliments the style of your other lighting fixtures. Most pictures show multiple sconces but here’s an example of a single one over a sink, like you would have. If you didn't do a light, I would leave it as is. After the shelves are up, see how you feel about the space and if it needs anything. (Use some black items on the shelves to help balance the hood.) I also think a roman shade in the window would look great.
