 - Viewport: 420 × 820 CSS px at device scale factor 1; implementation image is 420 × 820 px.
 - Source image: 144 × 343 px and only shows the compact icon-navigation language. It does not define the requested all-projects dashboard.
 - State: signed-in light theme, “工作台 / 全部项目” selected, one pending task and one latest file. The content header is “全部项目” with its creation action aligned on the right.

+- Primary interactions tested: default all-projects homepage, task editor modal, dataset-backed explore view, project picker, project-only right navigation, document panel, AI panel, and profile dropdown. Console errors: none.
 
 ## Evidence
 
 - Full current implementation: `test-results/app-home.png`
+- Explore reading flow: `test-results/app-explore.png`
 - Earlier focused icon-rail comparison: `test-results/design-qa-rail-comparison.png`
 
 The source rail is used only for the compact icon treatment. The latest requested behavior intentionally hides that rail in the all-projects dashboard and displays it only after selecting a specific project.
@@ -25,10 +26,12 @@ No actionable P0, P1, or P2 findings.
 - Colors and visual tokens: workbench/explore selection uses the existing blue token, while statistic colors distinguish projects, pending work, files, and plan tasks without overpowering the task list.
 - Image and icon fidelity: the existing product mark is retained and all controls use the installed Arco icon set; no placeholder or hand-drawn image assets were added.
 - Copy and content: “工作台”, “探索”, and “全部项目” make scope explicit; its homepage shows only pending tasks and latest files. The project-only menu contains 概况、计划、资料、AI、计划任务 and no longer exposes 收集箱.
+- Explore parity: the desktop view now uses the `web_v1` dataset endpoints and mirrors its core source-selection, item-list, and detail-reading workflow in a narrow reading layout. With 全部项目 selected, the “沉淀到项目” action is intentionally disabled until a concrete project is selected.
 
 ## Comparison history
 
 - Current pass: removed the completed-task section and upload action from the all-projects homepage, then removed the content-level “工作台” label and moved 创建项目 beside 全部项目. Re-captured `test-results/app-home.png` and verified that only pending tasks and latest files remain.
+- Explore pass: replaced the project-card placeholder with the dataset source and item reader. Captured `test-results/app-explore.png`; two sources and the selected article detail render without console errors.
