+- Delete-confirm implementation: `/Users/caoxiaozhu/.codex/visualizations/2026/07/14/019f5e2e-3bee-77f0-b285-89ef139db56c/dataset-version-build/implementation-delete-confirm.png`
+- Full-view comparison: `/Users/caoxiaozhu/.codex/visualizations/2026/07/14/019f5e2e-3bee-77f0-b285-89ef139db56c/dataset-version-build/comparison-full.png`
+- Focused version-control comparison: `/Users/caoxiaozhu/.codex/visualizations/2026/07/14/019f5e2e-3bee-77f0-b285-89ef139db56c/dataset-version-build/comparison-version-controls-final.png`
+- Viewport: 1316 × 768 browser window; source crop normalized for the focused comparison.
+- State: authenticated dataset detail, V3 current, V2 selected as a read-only historical version.
+
+## Full-view comparison
+
+The existing product shell, dataset summary, version selector, read-only alert, file toolbar, and sample table remain unchanged. The former standalone primary action has been replaced by one compact rounded-square overflow button at the far right of the version-control row, matching the selected hierarchy.
+
+## Focused comparison and required fidelity surfaces
+
+- Fonts and typography: existing system/PingFang stack, 13px labels, 12px metadata, and Element Plus menu text are preserved.
+- Spacing and layout rhythm: the 40px overflow trigger aligns with the version selector and leaves the central status copy flexible; the 168px menu provides 40px action rows.
+- Colors and visual tokens: the existing indigo primary token is used for the activate icon; the delete item and confirmation action use the danger token.
+- Image and icon fidelity: no new raster assets are needed. Existing Font Awesome ellipsis, check-circle, and trash icons match the repository's icon system.
+- Copy and content: the menu contains exactly “设为当前版本” and “删除版本”, separated visually; the confirmation names V2 and explains that current V3 is unaffected.
+
+## Interaction checks
+
+- Created V2 and V3 through the real edit-and-save flow, then switched from current V3 to historical V2.
+- Historical records became read-only and the overflow trigger appeared; current V3 showed no history-operation trigger.
+- Opening the trigger exposed exactly two accessible menu items: “设为当前版本” and “删除版本”.
+- Choosing “删除版本” opened the danger confirmation dialog; cancelling returned focus without deleting data.
+- Actual deletion behavior, protected-version rejection, optimistic-lock handling, and non-reused version numbers are covered by `test:dataset-preview`.
+
+## Comparison history
+
+### Iteration 1 — blocked
+
+- [P2] The overflow trigger was circular while the selected mock used a small rounded square.
+- [P2] The menu did not explicitly lock its target width or primary-action icon color.
+
+Fixes:
+
+- Replaced the circular trigger with a 40px square and 10px radius.
+- Set the menu minimum width to 168px, action height to 40px, and the activate icon to the product primary color.
+
+### Iteration 2 — passed
+
+No actionable P0/P1/P2 differences remain. The desktop capture API does not retain the transient popup layer in screenshots, so the open-menu labels were additionally verified through the accessibility tree; exact popup shadow rendering remains a non-blocking P3 capture gap.
+
+final result: passed

+
+## Evidence
+
+- Source visual truth: `/Users/caoxiaozhu/.codex/generated_images/019f5f3f-f7e1-7e41-9605-ea307d9f09e6/exec-d376c603-0c47-45ad-86fd-3e99c1a95ec7.png`
+- Implementation route: `http://localhost:6801/login`
+- Implementation screenshot: unavailable because the in-app browser runtime could not initialize in this session.
+- Intended desktop viewport: 1536 × 1024.
+- Intended laptop viewports: 1366 × 768 and 1280 × 720.
+- State: unauthenticated login page, default username and password populated.
+
+## Static and automated evidence
+
+- Added a 1440px width breakpoint that shifts the split from 58/42 to 55/45 and caps the form at 440px.
+- Added a short-screen breakpoint for heights up to 820px that reduces title, form, input, footer, and panel spacing without hiding the left visual.
+- Kept the single-column fallback at 900px and below.
+- `regression-login-layout.mjs`: passed.
+- `regression-default-dashboard.mjs`: passed.
+- `vue-tsc -b --noEmit`: passed.
+- Vite dev transform for `LoginView.vue`: HTTP 200.
+- Production build: blocked by the pre-existing missing route component `UserPermissionView.vue`, outside the login-page change.
+
+## Required fidelity surfaces
+
+- Fonts and typography: code uses the existing product font stack with laptop-specific display-size reductions; visual comparison remains unavailable.
+- Spacing and layout rhythm: dedicated width and height media queries are present; rendered measurements remain unavailable.
+- Colors and visual tokens: existing indigo tokens and the selected dark-purple visual asset are preserved.
+- Image quality and asset fidelity: the generated `login-hero-flow.png` is used directly; the official `logo.png` is reused for the brand lockup.
+- Copy and content: platform title, supporting copy, form labels, actions, and footer match the selected design.
+
+## Findings
+
+- [P2] Browser-rendered laptop comparison unavailable
+  Location: login page at 1366 × 768 and 1280 × 720.
+  Evidence: the in-app browser runtime failed during initialization, so no implementation screenshot or side-by-side comparison could be captured.
+  Impact: static checks cannot prove that all visible spacing and crop details match the selected design at laptop sizes.
+  Fix: capture both laptop viewports in a working in-app browser session, compare them with the source, and resolve any remaining P0/P1/P2 differences.
+
+## Comparison history
+
+### Iteration 1 — blocked
+
+- User reported that the initial implementation was optimized for large displays and did not compose well on laptop screens.
+- Added explicit laptop-width and short-screen layout rules and passed targeted regression/type checks.
+- Post-fix visual evidence remains unavailable because browser capture is blocked.
