- Full-view comparison evidence: `C:/Users/董宏凯/AppData/Local/Temp/position-roundtable-revised-comparison.png`
- Viewport: 1280 × 720. Light route: `#/page/strategy/qa/position-roundtable`; dark embedded route: `#/page/strategy/qa/position-roundtable?embed=1&theme=dark`.
- State: local browser has no authenticated API session. The original intent API is invoked and reports `Authentication required`; business-chain and agent endpoints return no usable data.

**Findings**

- [P1] Populated agent and business-chain states cannot be compared yet.
  Location: right agent list and non-planning-role chain diagram.
  Evidence: reference images show populated cards and nodes; the implementation has `0 个` agents and no available business chain in the unauthenticated preview.
  Impact: card density, selected-card indicator, chain node flow, and agent-detail transition cannot be truthfully verified against live data.
  Fix: verify the route in an authenticated session with at least one public chain and tagged agents.

**Open Questions**

- The final business-chain stage arrangement is still pending product confirmation. The compact graph maps whatever stage configuration is returned, while intentionally omitting dependency-label text as requested.

**Implementation Checklist**

1. Left task panel is now display-only and retains its independent position-roundtable task adapter.
2. Business-chain selection uses the original roundtable card/radio/relationship-entry pattern.
3. Every position uses the original `useStep1Intent` interface and `Step1Panel` message list/input panel; only the position header changes.
4. The right switch now uses the exact `课题研究 / ai写作` segmented-control treatment (light gray track, white active state; dark blue glass equivalent).
5. The embedded layout widens the left panel to 360px and applies the deep-blue right-panel tokens used by the reference.
6. Other roles render a taller top-to-bottom card-node flow without dependency labels. The canvas supports mouse-drag panning, and each node retains only a name plus a single-line description.

**Follow-up Polish**

- [P3] If live content is unusually long, tune the compact flow node width or horizontal scrolling after seeing the production chain data.

**Comparison history**

- Iteration 1: task fields were editable and the right TDesign card tabs looked unlike the reference. Replaced the task form with display-only information and replaced the tabs with the existing `课题研究 / ai写作` segmented switch.
- Iteration 2: business-chain selection was a dropdown and the flow was vertical avatar chips. Replaced it with original-roundtable selection cards and compact business-chain configuration-style node cards with link lines but no dependency labels.
- Iteration 3: dark right-panel background differed from the supplied deep-blue reference. Applied the `#032650` / `#042b59` / `#2b8ffe` token family and captured the revised embedded dark state in the full-view comparison.
- Iteration 4: removed the custom disabled input from non-planning positions and reused the original roundtable input panel. Enlarged the left flow viewport, retained its connection lines, and removed node level/seat/status metadata.
- Iteration 5: converted the compact flow from left-to-right to top-to-bottom. Added mouse-drag panning and single-line description truncation; populated-chain visual QA remains blocked by the unauthenticated preview.
- Iteration 6: constrained the flow canvas to its card viewport, narrowed nodes from 190px to 158px, and realigned branch gaps plus connector anchors to prevent clipping and offset lines.
