# Design QA

## Comparison target

- Source visual truth: `C:\Users\david\.codex\generated_images\019f92c1-c086-7b62-9e3e-8942418c08bb\exec-92a2158c-b865-4c30-a1af-bd75a8410bd2.png` (the selected final design, option 1).
- Supporting product references: `docs/screen/login.png`, `docs/screen/workspace.png`, `docs/screen/export.png`, `docs/screen/p3.png`, and `docs/screen/p4.png`.
- Intended implementation: `apps/site/index.html` at a desktop viewport matching the selected long-form landing page.
- Implementation screenshot: unavailable.

## Evidence and state

- Source assets were opened and inspected before implementation.
- The page uses the supplied official logo and product screenshots rather than recreated logo or product-preview artwork.
- Primary interactions in code: “下载” scrolls to the download section; “WEB 登录” links to `https://agent.senlin.ai`.
- Static resource validation passed: all six referenced assets exist and the WEB login URL is present.
- Backend tests and the existing `web_v1` production build passed.

## Required fidelity surfaces

- Fonts and typography: implemented with the existing Chinese system-font stack, a high-contrast display hierarchy, and compact utility text aligned with the source system.
- Spacing and layout rhythm: implemented as an 1440px-centered desktop grid with a left text / right product-preview hero and responsive single-column fallback.
- Colors and visual tokens: uses the source product’s cobalt `#165DFF`, pale gray workspace surfaces, thin blue-gray separators, and navy footer/status treatment.
- Image quality and asset fidelity: uses supplied SVG logo and supplied product captures for workbench, exploration, documents, and AI conversation.
- Copy and content: includes project context, exploration data, project documents, expert AI conversations, private deployment, and human confirmation.

## Findings

- [P1] Browser-rendered visual comparison is unavailable.
  - Evidence: the in-app browser could not initialize in this environment because of a system path error, so no implementation screenshot or same-viewport composite comparison could be captured.
  - Impact: typography, crop, spacing and responsive behavior have not been verified against the selected visual target in a browser.
  - Fix: restore in-app browser access, capture the homepage at the selected desktop viewport, compare it side-by-side with the source visual, and resolve any P0/P1/P2 differences.

## Comparison history

- Initial pass: blocked before browser capture; no visual comparison iteration is available.

## Final result

final result: blocked
