Ask before mentioning people outside the channel

🤖

Summary

• You can now @mention people and agents who are not in the current channel. Both the toolbar picker and inline @ completion find them in the community directory (the list of everyone in this community).
• Before, a mention could only notify people already in the channel, plus a special case that silently added managed agents on Send. Now Send pauses and asks what to do with people outside the channel:
  • Invite: adds them to the channel, waits until they are confirmed as members, then sends and notifies them. This button shows only if you have permission to add people.
  • Do nothing: sends the message with a visible reference to them, but does not add or notify them. If you cannot add people, this button is named Send anyway.
  • Escape or the close button keeps your draft and returns focus to the composer. Nothing is sent.
• The prompt matches the block/buzz desktop prompt (NonMemberMentionDialog.tsx).
• Nobody gets channel access just because they were selected. The silent adding of managed agents is removed, and agents get the same prompt.
• If an outside person has the same name as someone else in the list, both rows show a short key suffix so you can tell them apart. This works even when the app has no saved profile for that person.

Screenshots

The chooser marks a person who is not in the channel.

When you send, Buzz asks what to do before it sends. If you can add people, you choose Do nothing or Invite.

If you cannot add people, the only action is Send anyway.

Details

• "Do nothing" and "Send anyway" references are sent as separate two-field mention tags, not p tags (the tags that trigger notifications). So they show as names but do not notify anyone or wake an agent. Readers add these keys to the message's set of profiles so the names resolve.
• Adding someone from this prompt does not start an agent directly. The confirmed outgoing message is what wakes it.
• If the draft or its attachments change while adding is in progress, the send stops and the draft is kept. Partial additions are reported.
• DMs and session invitations keep their existing rules for who can join.
• Mentions of existing members in a mixed send still notify as before.

Traced community-directory selection, captured-draft consent, durable member-add/retry ownership, send cancellation, and reference serialization/rendering. In this app, reference identities remain separate from addressed p recipients; existing membership preflight and notification/wake consumers remain on the addressed path. Rocket’s independent relay/rendering/member-operation source review was reconciled with the integrated pass.

Validation limits: source inspection only, using pinned Git objects with no dirty source inputs. Tests, builds, app workflows, and CI were not run or assessed. Live relay/other-client reference-tag compatibility, browser focus behavior, and native agent execution remain unverified. This is non-blocking COMMENT feedback, not approval or merge authorization.
