Continuous aluminum gutters are the way to go. Good gutter companies will usually provide gutters in a slightly heavier gauge for a small upcharge. It's worth it. Get the hidden hangers, not spikes. Prices tend to vary quite a bit so get 3-4 quotes.
The return must be sized based on CFM required. Then consult a table showing the CFM capacity of various sizes of duct. This is run in conditioned space so if round won't fit, rectangular likely will.
You all are right. We do follow the 2017 NEC, not the 2008.
I was seeking to use only GFCI breakers instead of GFCI outlets. If I have to provide GFCI protection on these six circuits then I won't be able to use the tandem breakers I was hoping to use, and that will put me over capacity on...
My jurisdiction, Portland OR, follows the 2008 NEC.

Just read this entire thread in one sitting. Bravo!
You don't need to buy a black oxide kit. You can do it yourself with a gallon of "Prep N Etch" from Home Depot, a wad of steel wool and a bag of manganese dioxide that I ordered too much of.
PM me and I'll mail you some and you will be good...
You need ventilation.
Easiest would be mushroom vents cut into the roof and soffit vents cut into the blocking or the soffits (depending on whether you have finished soffits).
Can't enclose that space without venting.
I am really digging the geothermal/hot water management side of it. Super clean work. Very pleased to see a large home complemented by energy efficiency. Will the pool be somehow integrated? A heated pool in MD will be an energy hog.
I hope there is something special being done for the...
It's nice to see smart people design and create something special. I have no doubt that you were put on this earth to do exactly what you're doing.
What a great place. Thanks for sharing this.
