R8 the Mastodon API made real: featured tags, endorsements, notes, notify and languages, suggestions, the direct stream

Featured tags per persona (/api/v1/featured_tags, suggestions, tags/:name/feature, accounts' featured tags, max 10),
listed at /tattoos as Hashtags and sent as Add/Remove{Hashtag} to followers on the featured collection, as Mastodon
sends them; remote accounts' tags received and read from featuredTags. Endorsements (pin/endorse) and private notes
(PersonaNote) kept per persona and never federated; the relationship's notifying, languages, endorsed and note, with
follow's notify (status notifications) and languages (home filter). Reading preferences set on /clientapi. Suggestions
v1/v2 with dismissals and staff picks, never the persona or a sibling. conversation events on the direct stream.
translate, annual reports and the admin API answer. New collections backed up and removed with their persona.

+  - R8 the Mastodon API made real (built 2026-10-18, not yet deployed; `tools/pasture/scenarios/featured.sh`): featured
+    tags (`/api/v1/featured_tags`, suggestions, `tags/:name/feature`, accounts' featured tags, `max_featured_tags` 10;
+    `/tattoos` a collection of `Hashtag`s, `Add`/`Remove{Hashtag}` sent to followers and received, remote accounts'
+    `featuredTags` read with their counts); endorsements (`pin`/`unpin`, `endorse`/`unendorse`, `/api/v1/endorsements`);
+    private notes per persona (`PersonaNote`); the relationship's `notifying`, `languages`, `endorsed` and `note`, with
+    `follow`'s `notify` (a `status` notification) and `languages` (filtering the home); preferences' reading settings;
+    suggestions v1 and v2 with dismissals and the administrators' staff picks; the `direct` stream's `conversation`
+    events; translate, annual reports and the admin API answering. Chosen while building it, for the owner to confirm:
+    **featured tags federate** (they are public on Mastodon; `Add`/`Remove{Hashtag}` target `featured`, as Mastodon
+    sends them, rather than `featuredTags`, which Mastodon ignores); endorsements are never federated and
+    `/accounts/:id/endorsements` answers only the persona's own, to itself; suggestions never name a sibling persona and
+    count `most_followed` only from three followers here; `familiar_followers` stays empty; the reading preferences are
+    set on `/clientapi/avatar/private/preferences` (Mastodon's API sets none); staff picks have their own routes, not the
+    settings form; a `Move` carries the persona's endorsement and note to the new account; featured tags, notes and
+    endorsements are left out of the persona archive (Mastodon's layout has none), its `following_accounts.csv` now
+    carries notify and languages.
