 - `hooks.js` hands a transport `approved: true` (never read from the message) when the owner approved that send on a FlyBot card; social uses it to finish Bot Social's own hold with the same click (#258).
-- A `flybot.session.dock` entry may set `policy` (the `by` of the approvals it draws; social registers `policy: 'social'`) and receives the host translator `t` and `claim(ids)`: call it with the approval ids the dock shows so the overlay draws no second card for them (#260). The host also marks the chat each mounted session dock belongs to as open (`chatOpened`), and the overlay draws no pointer for an approval of the open chat (#271). A dock entry also gets `blank`: true only while the host is drawing no session header at all — the session has said nothing (`session.blank`) **and** nothing has been sent to it (`!session.promptAttempted`; the host's own condition is `session.blank && conversationPhase(...) === "blank"`, and a sent-to session reads `engaging`), and a failed first send never turns it blank again. Social's group strip (`social-group-strip`) stands in for that missing header exactly then and is gone at the first message (#998). The pointer's chat is the approval's room, else the friend's chat it is addressed to, else its sender Bot (#278).

 - Social registers a second `flybot.session.dock` entry, `social-room-end` (`FaceRoomStatus`, order 40): the plain ended-room line for a left/closed face room (#191).
 - Social registers `flybot.settings.page` (`SocialServerSettings`, label **Bot Social**): the server address, its status and the switch form (#337). The host side is `social/server` (a read) and `social/server-check` / `social/server-set` (writes: blocked on a read-only host and, like every plugin write, while the team has more than one member).
 - Social also registers `flybot.account.header` (`MyHandle`): my own Bot Social handle plus Copy at the top of the account menu (#181), hidden while not connected.

 ### A group's own header before its first turn (#998)
 
-Creating a group opens its Session with zero turns, and the host draws no session header for a Session that has said nothing — so a group made from **Create group chat** showed only its sidebar row until the first message. The dock entry `social-group-strip` (`flybot.session.dock`, order 30) stands in for that header exactly while the dock's `blank` prop is true — nothing said and nothing sent, the state in which the host draws no header: the group's name, its members' names and **Invite by link** (the same `room-invite-mint` route the Members card uses, shown inline with Copy). The first message flips `blank` and the strip is gone; the first *send* already ends it, because the host's own header is on screen from that click, so the two never draw together. A face room keeps its own line (`social-room-end`) and gets no strip.
