Acceptance criteria

Extraction

<Reasoning> component extracted from event-log.tsx into components/agent/reasoning.tsx as a standalone component with no event-log coupling

Transcript integration

planner/transcript.tsx renders a <Reasoning> accordion below the assistant bubble content when the turn contains thinking blocks
Collapsed by default; expands on click
Pulse animation only while the turn is actively streaming
Streaming thinking content appended incrementally via existing SSE path
Persisted turns: thinking blocks loaded from m.thinking field in the message record if present
Accordion hidden when thinking array is empty or absent

Quality

Event log <Reasoning> usage unchanged after extraction (refactor only)
just qa passes

Out of scope

Showing thinking blocks in non-architect sessions (only architect uses extended thinking today)
Thinking block search or copy-to-clipboard
Configuring whether thinking is shown/hidden

As a dashboard operator, I want to see the architect's reasoning process inside the transcript, so that I can understand why a particular recommendation was made without having to open the event log and hunt for a Reasoning accordion. ### Acceptance criteria #### Extraction - [ ] `<Reasoning>` component extracted from `event-log.tsx` into `components/agent/reasoning.tsx` as a standalone component with no event-log coupling #### Transcript integration - [ ] `planner/transcript.tsx` renders a `<Reasoning>` accordion below the assistant bubble content when the turn contains `thinking` blocks - [ ] Collapsed by default; expands on click - [ ] Pulse animation only while the turn is actively streaming - [ ] Streaming thinking content appended incrementally via existing SSE path - [ ] Persisted turns: thinking blocks loaded from `m.thinking` field in the message record if present - [ ] Accordion hidden when thinking array is empty or absent #### Quality - [ ] Event log `<Reasoning>` usage unchanged after extraction (refactor only) - [ ] `just qa` passes ### Out of scope - Showing thinking blocks in non-architect sessions (only architect uses extended thinking today) - Thinking block search or copy-to-clipboard - Configuring whether thinking is shown/hidden ### References - agent-output-unification audit 2026-05-15 - Inconsistency: "Thinking Block Rendering" (HIGH)
