Stacked on #6592; mark ready once it merges. Draft only because this branch builds on conversations-ui-cleanup; the diff against main includes #6592 until it lands.

Summary

  • The voice (mic-cloud) chat surface now renders its transcript with the assistant-ui Thread. Only the input changes: the voice footer (mic, voice-chat control, mascot dock, footer Cancel, gate cards, token stats) goes into a new Composer replacement slot on Thread, exposed as AssistantUiChat's composerReplacement prop.
  • The Workflow Copilot renders its dedicated builder thread through the same assistant-ui Thread, on its own AssistantUiRuntimeProvider threadId={threadId} (the existing external-store runtime; no new store). Its authoring footer (error, proposal diff and accept/reject, capped card, builder composer) goes into the Composer slot. Its empty hint is the Welcome slot. Delegation cards open the sub-agent drawer through SubagentDrawerHost + TranscriptOverlays.
  • Deletes the legacy transcript chain now that nothing mounts it: ChatThreadView, TranscriptRow, PastTurnInsights, UserTurnBody, CitationChips, InterruptedAnswer, aui/AgentInsightsSlot, aui/StreamingPreview, aui/AuiPlainText, aui/TranscriptStates, utils/interimNarration, timeline/selectors + timeline/types. Also deletes the modules that became orphaned with it: useStickToBottom, ChatNewWindowHero, and ai-elements Conversation/Message. All tests for these are removed too.
  • Removes state that is now dead: chatRuntime.interruptedAssistantByThread and the parallel-lane (parallelStreamsByThread, parallelRequestThreads, registerParallelRequest/setParallelStream/clearParallelRequest and the provider routing for them), theme.agentMessageViewMode/hideAgentInsights, threadSlice.persistReaction, AgentMessageText, useAuiThreadRunning. Also removes the unreachable legacy voice-record/TTS code in Conversations.tsx (inputMode/replyMode was never set to voice).
  • Net: about 6.7k lines deleted and 0.75k added under app/src.

Problem

  • ChatThreadView was still mounted in two places. One was Conversations.tsx legacyMainPanel, used for composer === 'mic-cloud'. The other was WorkflowCopilotPanel. That kept a second transcript renderer alive with its own ordering, previews, test ids and Redux state. Because the voice panel was an either/or with the assistant-ui panel, anything wired only into one of them silently went missing from the other. The agent-process-source command, for example, had to be disabled in voice mode.

Solution

  • thread.tsx gets one new ThreadComponents.Composer slot. When it is set, it replaces the built-in composer and its welcome suggestions in the viewport footer, so the transcript stays assistant-ui. AssistantUiChat renders the replacement through a stable-identity, ref-read slot, the same pattern it uses for the other slots, so MicComposer state survives host re-renders.
  • useOpenHumanExternalStore / AssistantUiRuntimeProvider take welcomeSuggestions (default true). The copilot turns it off because a starter click sends a home-chat prompt to the builder.
  • Copilot parked approvals: the footer ApprovalRequestCard/IntegrationConnectCard duplicate is dropped. The assistant-ui transcript already renders the approval inline on the gated tool call (ChatToolParts), as it does on /chat.
  • The copilot keeps its existing ChatComposer (built on ComposerPrimitive) inside the slot. The structured flows_build send path (submit, prefill/build modes, pending-ask carry-forward) is unchanged, and the null-thread-before-first-send case needs no chat-surface registry change.
  • The agent-process-source palette command is now enabled in voice mode too, because TranscriptOverlays is mounted in both modes.

Submission Checklist

  • Tests added or updated: WorkflowCopilotPanel.thread.test.tsx (real Thread: builder thread rendered, not the home thread; footer in the Composer slot; no chat composer or starters). AssistantUiChat.slots.test.tsx (replacement composer swaps only the composer and keeps its identity across re-renders). Conversations.processSourceCommand.test.tsx (voice mode renders the aui viewport + voice composer, and the command is enabled). Conversations.sidebarOverflow.test.tsx (voice composer sits inside the scrolling viewport, UI elements hidden when window is too small, obscuring actionable error states #3785). Existing copilot and runtime tests are retargeted from the ChatThreadView mock to Thread.
  • Diff coverage ≥ 80%: not measured locally; CI will report it. The changed lines are mostly deletions.
  • Coverage matrix: N/A, no feature rows added or removed (a rendering migration).
  • Affected feature IDs: N/A, see above.
  • No new external network dependencies.
  • Manual smoke checklist: N/A, no release-cut surface change beyond the transcript renderer.
  • Linked issue: N/A, stacked cleanup follow-up to fix(chat): one copy of each turn, real tool labels, sources as assistant-ui parts #6592.

Impact

  • Desktop only (frontend). Voice mode loses the legacy-only transcript affordances that text mode had already lost when it moved to assistant-ui: the per-message share button, emoji reactions, the "interrupted answer" restored bubble, and parallel (Cmd+Enter) branch sends. features/share/ShareMessageButton is kept but is now unmounted. Follow-up: wire it into the assistant-ui action bar, or delete the share feature.
  • Persisted theme state keys agentMessageViewMode / hideAgentInsights are dropped from the persist whitelist. Old values are ignored, with no migration needed.

Related

  • Closes: N/A
  • Follow-up PR(s)/TODOs:
    • chatRuntime.turnTimelinesByThread / turnTranscriptsByThread (and their hydrate thunks) are now write-only. They were read only by the deleted PastTurnInsights. Removing them touches the derived-transcript restore path, so it is left for a separate PR.
    • ShareMessageButton / share feature is now unmounted (see Impact).
    • /dev/agent-insights (AgentInsightsPreview) is kept because it previews ToolTimelineBlock + AgentProcessSourcePanel, which are still live via the command-palette process-source view.

Behavior Changes

  • Intended behavior change: voice mode and the workflow copilot render the assistant-ui transcript.
  • User-visible effect: same message and tool-card rendering in voice mode and in the copilot as on /chat. Copilot approvals appear inline on the tool call instead of as a separate footer card.

Parity Contract

  • Legacy behavior preserved: voice footer controls (mic, voice-chat control, mascot dock, footer Cancel, gate/error banners, back-to-parent breadcrumb, token stats, background-processes button, files chip). Copilot send path, seeds, proposal/capped cards.
  • Guard/fallback/dispatch parity checks: the mic submit guard (!selectedThreadId) is unchanged, and the copilot still registers its chat surface for runtime cancel.

📝 Walkthrough

Walkthrough

Home chat and workflow copilot now render transcripts through the shared assistant-ui Thread. The change adds composer and source slots, updates tool labels and source parts, removes parallel-stream and interrupted-answer runtime state, and deletes the replaced legacy transcript components and utilities.

Changes

Shared assistant-ui Thread

Layer / File(s) Summary
Thread slots, message parts, and tool labels
app/src/components/assistant-ui/thread.tsx, app/src/features/conversations/components/AssistantUiChat.tsx, app/src/providers/assistantUiMessages.ts, app/src/features/conversations/components/aui/ChatSources.tsx, app/src/utils/toolTimelineFormatting.ts, app/src/features/conversations/components/AssistantUiToolCall.tsx, related tests		 The Thread supports host-provided composer and source-group components. Message projection adds URL source parts and tool-label artifacts. Tool labels use shared formatting, and ChatSources renders a collapsed source list.
Home chat and copilot Thread integration
app/src/features/conversations/Conversations.tsx, app/src/components/flows/WorkflowCopilotPanel.tsx, app/src/providers/AssistantUiRuntimeProvider.tsx, app/src/providers/useOpenHumanExternalStore.ts, related tests and E2E specs		 Home chat uses the assistant-ui transcript in text and voice modes; voice mode replaces only the composer. Workflow copilot renders its builder thread with authoring controls in the Composer slot and no welcome suggestions. The process-source command is enabled in voice mode when a thread is selected.
Primary stream and snapshot state
app/src/store/chatRuntimeSlice.ts, app/src/providers/ChatRuntimeProvider.tsx, related tests		 Parallel request lanes and interrupted-answer buffers are removed. Stream deltas and completion or error handling use the primary thread paths. Interrupted snapshot tests now check lifecycle state without expecting a live partial-answer buffer.
Retire replaced transcript components and state
app/src/features/conversations/components/ChatThreadView.tsx, app/src/features/conversations/timeline/*, app/src/features/conversations/components/aui/*, app/src/hooks/useStickToBottom.ts, app/src/store/themeSlice.ts, related tests and documentation		 The legacy transcript, timeline projection, scrolling hook, and related rendering components are deleted. Their exports, theme settings, tests, and documentation references are removed or updated.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Switch to the text composer for non-auto-send dictation.

When mic-cloud replaces the text composer, this handler only updates the hidden assistant-ui draft. The voice replacement has no text input or send action for that draft, so the transcript is not visible or sendable until the user manually switches to text. Restore the prior automatic handoff:

         void handleSendMessageRef.current?.(text);

       setInputValue(prev => {
         const base = prev.trim();
         if (!base) return text;
         return `${base}${base.endsWith(' ') ? '' : ' '}${text}`;

replaces the built-in Composer, allowing Quote actions that the host composer
does not use. Update the SelectionToolbar render in the thread component to

test(conversations): add process data to voice mode test
ae2b15e 
Add process data to the voice mode test for the agent-process-source command to verify that the command remains enabled when the composer is in mic-cloud mode, ensuring the voice mode does not introduce an additional gate on the command's availability.

fix(assistant-ui): hide selection toolbar when host composer is active
a15e938 
Hide the selection toolbar in the thread when the host composer is active, as the mic-first composer lacks a text surface for inspecting dictated drafts. When a dictated draft arrives, the composer is switched to text mode to provide the user with a visible editing surface before sending.
