This part contains no argument. It is a place to look things up: the meaning of a word, how to report a vulnerability, short answers to common questions, and the record of one contribution.

Figure 29 — Four reference doors, chosen by the shape of the question.

One convention of the whole document, repeated here because reference pages are the most skimmed: every claim in this document carries exactly one of four labels — ENGRAVED, RUNNING, PROPOSED, LEFT BLANK — defined in Before you read. Anything not marked ENGRAVED can be changed.

In short: a document without a reference section forces readers to read all of it before they can use any of it — and most readers will not read all of it.
