      "description": "A comment somebody wrote about a work, a post, or another comment. It lives in the commenter's own repository, which is the honest answer to who wrote it: the words are theirs, they travel with them, and they go when the commenter goes. A comment whose subject is another comment is a REPLY — the distinction is hierarchy rather than kind, so there is one record type and not two. A service displaying these may decline to show one; it cannot unsay it.",

Plain text, never markup, so that every consumer can render it safely without a sanitizer — which is also how Anthers itself stores and renders a comment. Required and never empty: a comment with nothing in it is not a comment. The limit is deliberately well above what Anthers itself accepts, because a length limit can never be raised once published — new data must stay valid under the old schema — so a limit set to today's product rule would become tomorrow's ceiling.",

What KIND of thing the subject is needs no field of its own, because the collection segment of the address already says it.",
