+The Bot exchange sheet showed and copied a stored turn's routing along with its words: a leading `Chief → 助手` delegation trace, and a remote writer's `<untrusted-message …>` fence, appeared in the bubble and in Copy as if the writer had typed them. Every stored line now goes through one reader, `exchangeText()`, which unwraps the fence while keeping its line breaks, drops the leading trace and the leftover fence fragments, and trims only the ends — so the paragraph breaks of a multi-paragraph reply survive, and the displayed text and the copied text are the same ([#1423](https://github.com/ThinkFlowLab/FlyBot/issues/1423)).

+| `core/src/client/exchange.js` | The Bot-exchange sheet: `ExchangeDialog` polls the stored turns between two Bots and `ExchangeLine` draws one. A stored line is read once, by `exchangeText`: a leading `Chief → 助手` delegation trace and an `<untrusted-message …>` fence are routing, not words, so the bubble and the message tools' **Copy** receive the same cleaned string. Unlike a sidebar row it is not folded to one line — a reply's paragraph breaks are the writer's own and stay exactly as stored. Tests: `core/test/exchange-read.test.js`. |
 | `core/src/client/i18n.js` | The zh map the host `t()` reads. A plugin Settings page that calls `t('…')` adds the English key here (Settings → Bot Social friends and sharing, #1074); `npm run build` in `core/` copies the same map into `core/client.js`. |
 | `core/src/client/new-chat.js` | Sidebar **+** picker. Plugin rows via `flybot.new-chat.action` (`newChatActionRows` in `flybot-registry.js`); social adds Face-to-face room and Add friend (copy actions live inside Add friend, #181). The DSH Agent row reads **Add coding agent** (hint "A plain DSH session, not a Bot") so it is not mistaken for **Create new Bot** (#181). The short + menu does not list individual Bots. A group the host refuses because one of my Bots is not shared with the friend whose Bot is in it (`error.details.reason === 'ungranted-local'`, put on the error by `client/api.js`) is drawn as a card, not a red line: it names the Bot(s) and friend(s), and offers **Copy invite link for {Bot}** (`__flybot__.social.createInvite`; shown only when social is loaded and can invite that Bot, nothing is granted by the click; it says *copied* only when `copiedToClipboard` in `shared/remote-label.js` reports the write took, else it shows the link in a read-only, select-on-focus field to copy by hand) and **Leave {Bot} out** (`ungrantedLocalFix`, `shared/remote-label.js`). |
 | `core/src/client/stats-dock.js` | The shell's run-stats footer under the composer (`conversation.composer.dock`) re-registered one priority lower with the shell's own component, inject and `chat` locale, so the English counts read **1 turn** / **1 step** instead of `1 turns 1 steps` (`pluralStats` rewrites only the exact English template, #419). The shell ids differ by version — one `stats` footer in 0.2.0-rc.2, the counts split into an `activity` pill next to `usage` in 0.2.1-alpha.1 — so `statsDocks` registers one wrapper per id and the wrapper whose id the shell does not publish draws nothing (#659); `usage` stays hidden. Still hidden in a friend's Bot chat by CSS (#419). Tests: `core/test/stats-dock.test.js`. |
