this seems to ignore the fact that Mercury is way too deep in Sol’s gravity well to be useful, all it’s looking at is Mercury mass.

Why does being so deep in the gravity well pose an issue? If you are assuming the Dyson swarm is intended to go back up the well then sure, but that isn't necessary.

I think I must be missing something important, because this doesn't make sense to me. If you put your mirrors in orbits where they don't block the dayside surface (sun-synchronous?), then they increase the total surface area receiving solar radiation.

Yeah, orbital mirrors essentially expand the radius of Mercury, increasing the sunlight available. Terrestrial mirrors would ensure that light makes it from the sunward side to the dark side of the planet.

Could you elaborate? Why would being deep in the gravity well be a non-starter? I thought Mercury's proximity to Sol was a huge advantage because of the ample solar power which would make planet-side manufacturing easier.

Does Mercury not have any useful radioactive material to provide more power?

Are there reactor designs that could work up there? There's not much water for coolant.

There are other substances that can be used for reactor coolant. Molten salt reactors are actually substantially more efficient than water-cooled reactors because they have a higher operating temperature. You can also use liquid metal as coolant, such as lead or bismuth.

This reads like an LLM plagiarizing this video from Kurzgesagt: https://youtu.be/pP44EPBMb8A?si=fSwWPOCnCsC1QEny

Kurzgesagt didn't invent the concept of disassembling Mercury to build a Dyson swarm. Stuart Armstrong proposed it in a lecture in 2012[0].

Pretty sure the idea predates that lecture, it appears in Charles Stross' novel Accelerando from 2005 (which is based on short stories that were published years earlier).

Also, the kind of satellites that aren't much more than mirrors, even with today's knowledge, they can be designed to change their profile/surface and thus reduce the absorption of the incident radiation, if they'd had to cross the space between the sun and the sunlight collector areas.
