What changed

  • treat a complete bot SSE announcement as a cross-client creation when the desktop does not know its id
  • insert that bot immediately with an empty transcript
  • continue folding the following greeting/message frames into the new bot
  • add a reducer regression test for the exact phone-created-bot event sequence

Root cause

The phone successfully created and persisted the bot, then applied the HTTP response locally. The desktop received the server's slim bot announcement but ignored unknown bots unless the event also carried a messages array. A full desktop refresh hydrated the bot, which made this look like creation had failed.

Impact

Bots created by the iOS companion, another desktop window, or an import now appear in every connected desktop roster immediately without a reload.

Validation

  • targeted reducer regression — passed
  • pnpm typecheck — passed
  • pnpm test — 973 passed, 8 skipped
  • updater coordinator tests — 12 passed
  • packaged-server smoke test — passed

Review Change Stack

📝 Walkthrough

Walkthrough

The store now accepts bot announcements without transcripts, creates unknown bots with empty message lists, and associates later greeting messages with those bots. Tests cover the cross-client creation and message-delivery flow.

Changes

Bot announcement state

Layer / File(s) Summary
Bot announcement contract and wiring
src/state/store.tsx
BotAnnouncement makes the transcript optional. botPatched actions and bot SSE announcements use this type. reducer and initialState are exported.
Unknown bot initialization and validation
src/state/store.tsx, src/state/store.test.ts
Unknown bot announcements create bots with empty message lists. Tests verify that a later greeting message is appended to the bot thread.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 20990

Cross-device bot creation can leave multiple bots marked as the primary coordinator when a newly announced bot has that role, causing inconsistent coordination behavior. This bounded correctness issue should be addressed before merging.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve chief-of-staff exclusivity for unknown bots.

Lines 554-558 return before the normalization at lines 569-576. If an announced bot has chiefOfStaff: true, existing bots can retain that flag. This violates the Bot invariant that there is one primary coordinator.

Clear chiefOfStaff from existing bots before inserting the announced bot.

Proposed fix
       if (!before) {
+        const bots = action.bot.chiefOfStaff
+          ? state.bots.map((bot) => ({ ...bot, chiefOfStaff: false }))
+          : state.bots;
         return {
           ...state,
-          bots: [{ ...action.bot, messages: action.bot.messages ?? [] }, ...state.bots],
+          bots: [{ ...action.bot, messages: action.bot.messages ?? [] }, ...bots],
         };
