feat(chat): group conversations and who reacted - #3582
Conversation
Groups (#3581): - New group button next to search: pick 2 to 7 people and start a group; the server's message is shown when someone does not accept messages or a limit is reached. - Groups are titled by the name their owner gave them, else by the other members, with two member avatars, in the list, the conversation header and name sorting. - A group's options offer its members and, for its owner, Rename; leaving reads as leaving a conversation. - A rename shows as a plain-text notice in the conversation and updates the header and the list. Who reacted (#3580): long-press a reaction to see who left each emoji, looking up anyone the screen has not loaded yet.
The avatar component styles its image rather than its wrapper, so the two group avatars are now positioned by wrapper views and stay inside their box. Avatars inside the group and reactor sheets no longer open a profile behind the open sheet. A group's name is never read as a community, and a new group without a loaded name is titled Group rather than by its id.

1. Reopened group picker cannot close 📜 Skill insight ≡ Correctness
ChatNewGroupSheet sets closedRef.current when it hides but never resets that ref or its selection state when the payload changes or the sheet is shown again. If the sheet instance is reused, a later successful creation or Cancel press reaches _close, which returns without hiding or delivering its result.
Agent Prompt
## Issue description
A reused new-group sheet keeps its closed flag and selection, preventing a subsequent close from completing.
## Fix Focus Areas
- src/components/chatGroupSheets/chatNewGroupSheet.tsx[44-50]
- src/components/chatGroupSheets/chatNewGroupSheet.tsx[88-93]
- src/components/chatGroupSheets/chatNewGroupSheet.tsx[136-142]
## Recommended Fix
Reset every picker state value and closedRef when the payload changes and in an ActionSheet onBeforeShow callback.

Not reachable: sheets mount on show and unmount on hide (SheetProvider renders !visible ? null : <Sheet/>, see CLAUDE.md "Sheets"), so every opening starts with fresh state and a fresh closedRef.

2. Group rename can retain the prior name 📜 Skill insight ≡ Correctness
ChatRenameGroupSheet initializes value from payload.currentName only once and does not reset it, its error state, or closedRef on payload change or before showing. Reusing the sheet for another group can present the previous name, and its already-set close guard prevents Save or Cancel from returning a result.
Agent Prompt
## Issue description
The rename sheet can reuse a previous group's name and closed flag.
## Fix Focus Areas
- src/components/chatGroupSheets/chatRenameGroupSheet.tsx[23-40]
- src/components/chatGroupSheets/chatRenameGroupSheet.tsx[70-76]
## Recommended Fix
Reset the input from the current payload, loading and error states, and closedRef in both a payload-dependent effect and ActionSheet onBeforeShow.
ⓘ Copy this prompt and use it to remediate the issue with your preferred AI generation tools

Same as above: the sheet unmounts on hide, so each opening initialises from that group's currentName with no leftover error or closedRef.

| ); | ||
| const [lookup, setLookup] = useState<Record<string, any>>(payload?.userLookup || {}); |

3. Reactor sheet can show stale people 📜 Skill insight ≡ Correctness
ChatReactorsSheet initializes selected and lookup from its payload without resetting either on payload change or in onBeforeShow. If a reused sheet receives reactions for another message, its displayed users can still come from the previous lookup, even though the reaction groups now reflect the new payload.
Agent Prompt
## Issue description
A reused reactor sheet keeps its previous selection and user lookup.
## Fix Focus Areas
- src/components/chatGroupSheets/chatReactorsSheet.tsx[24-35]
- src/components/chatGroupSheets/chatReactorsSheet.tsx[70-71]
## Recommended Fix
Reset selection and lookup from the current payload in a payload-dependent effect and an ActionSheet onBeforeShow callback.

Wait for chat bootstrap before enabling group creation
On a cold chat-screen entry, isLoggedIn is already true while _loadChannels may still be bootstrapping Mattermost, so this enables the button before the chat token exists. The new-group sheet calls searchMattermostUsers and createMattermostGroup directly without _ensureBootstrap; after a fresh login or account switch, an immediate search can therefore receive a 401 and be presented as an empty result list. Gate this action on bootstrapResult or ensure bootstrap before showing the sheet.

Fixed in 144e088: the New group button appears only once the chat session is ready.

Propagate remote group renames to the channel list
When another member renames the group while this thread is open, the WebSocket handler updates only groupInfo. The channel list behind the thread updates renamed groups solely through its GROUP_RENAMED_EVENT listener, but this path never emits that event, so navigating back continues to show the old title until a later manual reload. Emit the same list update here using the parsed new name.

Fixed in 144e088, see above: the live rename now updates the list too.

…embers - Searching the chat list matches a group's given name and its members. - A rename that arrives live from another member updates the list as well as the open header, and a channel fetch already in flight no longer puts the old name back. - The members list of a group or direct message shows only its members; it used to list everyone the screen had looked up, such as post authors and other conversations' partners. - New group waits for the chat session, and a failed people search says so instead of reading as no matches.

…mber - A list reload that started before a rename no longer puts the old group name back. - Search finds a named group by any member's name, not only by its name. - The members list of a group or direct message never falls back to everyone this screen has looked up: until members load, a group shows the members the chat list already knew.

Re the CodeRabbit outside-diff note on |
Closes #3580. Closes #3581.
Mobile side of who reacted and group conversations, using the chat API that web already uses.
Who reacted (#3580). Long-press a reaction to open a sheet with one tab per emoji, listing who reacted (you first). Reactors the screen has not loaded yet, such as someone whose reaction arrived live, are looked up once. Tapping a person opens their quick profile.
Groups (#3581).
Already covered on mobile, so nothing changed: live messages from people not yet loaded are looked up, and link previews exist.
Typecheck clean, 1179 tests pass (7 new for the group and reaction helpers), lint shows no new warnings. Not yet tried on a device: the development build after merge publishes the alpha for that.
