Post gains what federation and the Mastodon API need: Visibility (Public, Unlisted, FollowersOnly, Direct, Circle, LocalGeo), the author's account id, to/cc, the Create's id, url, context, quote, InReplyToURI and the parent's author, a separate SpoilerText next to the title, language, mentions, hashtags, remote attachments (alt text, blurhash, focus, size), reply/favourite/reblog counters, revisions, EditedAt and DeletedAt. Direct messages are Posts with Visibility Direct and a ConversationId; migration _005 copies DmPost rows across with their ids and fills the new fields of existing posts. DmPost is left in place so a rollback still sees the old messages. Inbound: - NoteParser reads Note, Article, Page, Question and media types: content, then contentMap, then _misskey_content; summary as the spoiler and name as the title; Mention and Hashtag tags; attachments; a PeerTube-style list attribution prefers the person over the channel; quote URIs. - Addressing classifies like Mastodon, finding followers-only by the author's own followers URL (now stored on ForeignAvatar), not by a "/followers" suffix. - Create keeps a post when a local persona is addressed or mentioned, when it replies to a local post (the parent's reply count goes up) or when a community it follows is addressed; an unsolicited public post is not stored. Update keeps the previous version as a revision. The outbox and object endpoints serve only Public and Unlisted posts.
