READ — asking the web surface a question

Raised by the read endpoints lemonfiber ui serves, about which read a request named and the query string it arrived with. A read that cannot be answered as it was asked is refused, because answering a different question in its place would read like the answer to this one. READ-3 answers 404, and every other one 400. See the envelope.

The release this page is built for does not carry what this part is read from. The next version's page has it.

What each severity and each exit means is on every error by code, beside every other family.
