I tried searching and came to the conclusion this does not exist. I would like a tablet with the following features:
I don't plan on using it for anything besides basic web browsing and pdf reading, so it should be cheap. However, price is no object if it has those features. There was one other soft criteria but it sounded like an ad so I removed it... See if you can guess.

Transreflective LCDs, see fancy 90s era marine GPS units etc.
Expensive, not good color rendition, backlit trad LCDs for smartphones pretty much killed the technology. Its all about best image quality in the showroom not real world, and transreflective will always be worse for some fundamental optical reasons in a dim-ish indoor room. Its a pity because transreflective will always look better pretty much anywhere else.
You can buy small "arduino project" style LCDs that are transreflective. They'll be monochrome alphanumeric and small, not 300 DPI truecolor the size of a page, but they're available.
Most of ops list of requirements are difficult to simultaneously meet but really easy to meet a subset, so the real question about the topic is what gets thrown under the bus. You could savagely 3-d print some horrendous frankenstein that uses an arduino with 100% open source firmware and a tiny little low res screen and nightmare UI, but OP probably wants something that'll actually work and not look hideous. Or dump the open source full ness and easy to repair and just buy a kindle reader although its really slow refresh rate.

What is so extreme about the requirements? The only technically demanding one is a wide dynamic range for screen brightness. The others are just design decisions.
