**Findings**
- No actionable P0/P1/P2 findings remain.

**Open Questions**
- The source visual is an Image Gen concept rather than a pixel-locked Figma file, so exact icon glyphs and logo geometry were implemented as code-native UI marks. The final prototype preserves the selected direction's hierarchy, density, risk states, and operational layout.

**Implementation Checklist**
- Source visual truth path: `C:\Users\bruce\.codex\generated_images\019e8bb8-b097-72b3-9c89-97cfca019c7c\ig_0fe578f839e33933016a1fae76771c81918c954bf5cbfe72d2.png`
- Implementation screenshot path: `D:\Code\DEMO-AGENT\output\playwright\command-center-v2-desktop.png`
- Mobile screenshot path: `D:\Code\DEMO-AGENT\output\playwright\command-center-v2-mobile.png`
- Full-view comparison evidence: `D:\Code\DEMO-AGENT\output\playwright\command-center-v2-comparison.png`
- Viewport: desktop `1440 x 1024`, mobile `390 x 844`
- State: default command-center workbench; desktop screenshot shows the selected direction's primary dashboard state.
- Focused region comparison evidence: not separately required; this is a dense dashboard concept and the full-view comparison makes the critical regions visible enough: sidebar, batch strip, metrics, workflow, audit table, and right risk rail.
- Fonts and typography: Segoe UI / PingFang SC / Microsoft YaHei fallback stack matches the professional enterprise SaaS feel; hierarchy and body sizes are readable, with no negative letter spacing.
- Spacing and layout rhythm: Desktop uses the same left rail, top context strip, four metric blocks, workflow strip, table region, and right-side risk rail as the source. Mobile switches to stacked sections to avoid cramped table-dashboard density.
- Colors and visual tokens: Deep navy sidebar, white work surface, cool gray borders, blue primary actions, red/orange/green semantic risk states match the selected visual direction.
- Image quality and asset fidelity: The source concept did not require product photos or decorative raster assets. The implementation uses lightweight UI marks and CSS primitives appropriate for a Django dashboard prototype.
- Copy and content: Chinese labels are aligned to the requirements: NMPA IVD review, registration batch, completeness check, risk gate, evidence, Feishu notification, responsible owners, and audit trail.
- Patches made since previous QA pass: added mobile wrapping for the header and batch strip, converted mobile actions to a single-column grid, adjusted the health legend, and suppressed horizontal overflow.
- final result: passed

**Follow-up Polish**
- P3: Replace letter-based placeholder nav icons with an icon font or library if the project later adds a frontend asset pipeline.
- P3: Add separate interactive tab bodies for consistency, evidence, and Feishu cards if the prototype needs a longer live demo script.
