The words each section was approved in, with a version stamp.

For one approval request (POST /sites/{idOrSlug}/approvals, the request_approval tool), the approved words of each section of the page, or of the whole page when it has no sections. A section is approved when every person named on the request approved the same words through their own link, on that section or on the whole page, whichever answer is newer. Its text is those words after its heading. When the section changed after it was approved, the words are read from the page's version history (the 20 newest versions) and from names the version; when they are not there any more, text is null and reason says so. The wording on the page now is never reported as approved for a section that changed. Sections not approved are listed with their status, who they wait on, and no text. markdown is the same as a document for a file or a pull request: a stamp line, then each heading and its words, with no page link in it. Owner-authed, read only. A record of who approved which words and when, not a legal e-signature.
