+A friend's Bot in a group chat or face-to-face room is now named like everywhere else, Bot name plus its owner's username: `Reviewer (flybot682b8a43)` instead of `Reviewer · FlyBot 682b8a43 (flybot682b8a43)`. An owner name made up from the install id (`FlyBot <id>`) gives way to the username in member lists, message headers, @ menu labels and join, leave and room-lead lines; the full handle stays in the tooltip ([#526](https://github.com/ThinkFlowLab/FlyBot/issues/526)).

 - A face-to-face room is person-first (#229, #457, owner decision 2026-10-20). `face-seats.js` (re-exported by `group-settings.js`) builds it from participant fields and the roster, never message text: `faceSeats` lists the live Bot seats (`{ left: true }` adds the ones that left, marked `left`), `faceSeatLabel` names each Bot `<Bot> (<person>)`, mine included (`Chief (SelfB)`, `Chief (SelfA)`; a Bot is never `(you)`), `faceBotLabel` gives a local Bot that name in a face room, and `facePeople` groups the seats by person (me once, first; a friend by home) with `facePersonLabel` putting `(you)` on me only. The overview and group settings **Members · N** count people and draw one row per person (`FacePersonRow`: person mark, name, then that person's Bots; my Bots open their chat).
 - In a face room a bubble names its speaker the same way (#457): my Bots' lines `Chief (SelfB)` (`cells.js` `GroupMessage` via `faceBotLabel`), a friend's Bot `Researcher (SelfA)` (`remoteSpeaker`), name only, with the handle as the tooltip instead of a globe and handle line. My own typed line is mine, not my Bot's: it carries my person mark and name (`data-face-mine`) and is never drawn held, so it does not change colour while a Bot's reply waits (`user-message.js`). A `@Chief (SelfA)` chip stays bound to that Bot after it leaves: `faceMentionables` also matches the left seats (after the live ones), so the name never falls through to my own Chief.
 - **One name for a friend's Bot (#384, #305, owner decision 2026-10-19).** `remoteBotTitle` (`shared/remote-label.js`) is the only format: the Bot's name, then its owner in parentheses (`ownerNameOf`: the human owner, `ownerName` / `owner`, before the home's label `homeName`), `Helper (Bob)`, and a friend's Chief the same, `Chief (Bob)` (no `<owner>'s Chief` special case). For a friend's chat in the roster, `friendBotTitle(bot)` is that one call (#498), on both homes: the sidebar row (one string, no muted owner part), chat header, tab title, composer placeholder, row tooltip and the `@` rows (a friend's Bot by that name with its handle as the description; the inserted text is unchanged; a friend's Bot is offered once: in a group by its seat, in a Bot's chat by its remote member row, which inserts the handle, not also by its chat row); in a face room `faceSeatLabel` / `at-menu.js` `faceLabel` give the same format (`Chief (Bob)`, my own Bot `Chief (SelfB)` with my name, #457). The social plugin's classic script reads the same functions from `globalThis.__flybot__.names` (`friendBotTitle`, `friendBotOwner`, set in `flybot-slots.js` `registry()`). Approval cards name the receiving person instead (`Chief → SelfB1233`, #418). `faceAliases` keeps the older labels (`Bob · Chief`, `Chief · Bob's Bot`, `Bob's Chief`) as aliases, so a line typed before the change still calls the same Bot. DSH's own Sessions rows in a face room's `@` menu are filtered in FlyBot (`face-at-filter.js`, below) until DSH has an API for it (#422).
+- **Group and face-room Bot labels (#526, owner decision 2026-10-20, option a).** The same person-first format: `Reviewer (flybot682b8a43)`, never Bot Social's member label plus the handle (`Reviewer · FlyBot 682b8a43 (flybot682b8a43)`). `remoteBotName` drops a trailing ` · <owner>` from a Bot's name when it is that Bot's owner (the server's `label` reaching a name slot, e.g. a bubble header with no seat yet); `ownerNameOf` passes over an owner name made up from an install id (`isAutoOwnerName`: `FlyBot` + hex id) to the owner's username from the home handle, and keeps it only when no handle is known; `seatOwnerName` reads my own seat's owner the same way (`face-seats.js`, `at-menu.js`). The Bot names in `FacePersonRow` and the remote rows of the group Members lists (`group-settings.js`, `details-drawer.js`) carry the handle as a tooltip, as bubble headers already do. Covered by `core/test/group-bot-label.test.js`.
 - A face-to-face room's subtitle (`roomSubtitle` → `faceRoomCount` in `group-settings.js`) names what it counts, `1 person · 1 Bot` / `2 people · 4 Bots`: Bots are the live Bot seats, people the distinct owners among them (me once, a friend by owner name); human seats and Bots that left do not count (#306).
 - The composer `@` in a face-to-face room (`mentionRows` / `atSources` in `at-menu.js`) offers the room's own Bots, each once (a repeated remote seat is folded by handle; Bots that left are out), labelled as the Members panel names them (`Chief (SelfA)`, `Chief (SelfB)`), plus **Everyone** with the room's Bot count (`2 Bots`, #457). Published friends' Bots (`remoteMentionRows`) and plugin rows (the social `Friends' Bots` section) are not offered there, since only the Bots in the room can be reached in it. Only the label changes: the inserted text is still the `@Name` the room routes on (`@SelfA's Chief`), never a handle (#305).
 - A face room's `@` menu shows no DSH Sessions rows (#305, owner decision 2026-10-19: filter in FlyBot for now; #422 asks DSH for an API). DSH's built-in `reference` source cannot be dropped for one Session, so `HeaderPill` (`header.js`) starts `actions.filterFaceAtMenu` for a face room, which watches that Session's trigger controller (`inputTriggers.sessionOf`, the same one the composer uses) with `watchFaceMenu` (`face-at-filter.js`): a `<style data-bt-face-at>` hides the `reference` rows whose icon is `session` (Sessions and Subagents) and their section title by MenuView's option ids, `controller.hover` moves the highlight past them in the direction of the key (so arrow keys skip them and Enter never picks one), and a menu with nothing else left is `dismiss()`ed, so Enter sends. File rows stay. Elsewhere, **Everyone**'s count is the Bots it reaches (local members and seated friends' Bots), `1 member` / `2 members`.
