Local text (Domain/Content/ContentRenderer): Markdig with raw HTML off and
autolinks, or plain text for API clients; then @user and @user@host are
resolved (locally or through WebFinger) into Mastodon's h-card markup and
#tags into hashtag links, skipping code, links and e-mail addresses. A
post stores the result, its mentions and its tags, and is delivered to
the mentioned actors and the parent's author as well as to followers.
Renderer:
- Mastodon's @context (toot, schema PropertyValue, discoverable,
indexable, blurhash, focalPoint, featured, alsoKnownAs, movedTo) and
FEP-2c59's webfinger;
- an actor's url is its HTML page, its fields are PropertyValue
attachments, published is cut to the day and indexable is false;
- a note's content is the stored rendering; a title becomes name and a
bold first line, a content warning without its own text is summarised
by the title or "Content warning"; Mention and Hashtag tags, contentMap,
updated, and to/cc by visibility.
Routes take the agreed names: /groupies, /stalking, /scribbles/{id},
/grunts/{id} (a Create resolves), /whispers/{id} for a DM's context. The
outbox is a collection with a first page, paged by max_id. A browser
asking for an actor or a note is redirected to /@user, and WebFinger's
profile-page points there.
