-- Browser-rendered open-state comparison: `/workspace/scratch/mobile-sidebar-open-comparison-20260908.jpg`

-- Browser-rendered closed-state comparison: `/workspace/scratch/mobile-sidebar-closed-comparison-20260908.jpg`
+- Browser-rendered implementation dimensions: `1363 × 936`.
-- Comparison screenshot dimensions: `1363 × 936`.
+- Focused side-by-side comparison: `/workspace/scratch/6e52996114b8/sidebar-popover-comparison-final-20260909.jpg`
-- Implementation CSS viewport: `543 × 936`, device scale factor `1`.
+- Implementation CSS viewport: `1363 × 936`, device scale factor `1`.
-- Density normalization: source and implementation are both displayed at `543px` CSS width; the source's bottom `42px` is outside the comparison viewport and contains no sidebar structure needed for this review.
+- State: PC dark theme, collapsed sidebar, pointer hovering the disabled “视觉风格” icon.
-- State: dark-theme project list, with the mobile navigation captured both open and closed.
 
 ## Full-view comparison evidence
 
-The source shows a permanently visible `48px` navigation rail that reduces the project-content width. The revised closed state removes that rail entirely: browser geometry reports the main region at `543px`, equal to the `543px` iframe viewport. The top-left control is now a menu icon and the project list uses the full available width.
+The implementation preserves the existing collapsed sidebar width, icon order, selected state and main-content boundary. Hovering an icon opens a compact Naive UI popover to the right without shifting the sidebar or content.
-
-The revised open state shows the same navigation as a `543 × 936` fixed full-screen layer. Brand, navigation items and the bottom backend entry remain vertically separated, while an explicit close icon is available in the navigation header.
 
 ## Focused region comparison evidence
 
-A separate crop was not needed because both states are rendered at 1:1 CSS width in the full-view comparison and the header controls, navigation item, content boundary and footer action remain readable.
+The focused comparison places the supplied sidebar crop beside a `320 × 506` crop of the browser render. The source icon spacing, dark surfaces and green selected state remain unchanged. The implementation adds the requested hover label beside the icon; disabled workflow items use the explanatory suffix “（剧本完成后可用）”.
 
 ## Required fidelity surfaces
 
-- Fonts and typography: existing font family, sizes, weights and truncation behavior are preserved. The drawer uses the same brand and menu typography as the desktop sidebar.
+- Typography: the application typography is unchanged; popover copy uses the current Naive UI theme and compact UI text sizing.
-- Spacing and layout rhythm: the closed state removes the previous `48px` content offset. The open state uses the full viewport and preserves the existing header, menu and footer spacing.
+- Spacing and layout rhythm: the `64px` collapsed sidebar and existing vertical menu rhythm are preserved. Popovers use `placement="right"` and do not alter document flow.
-- Colors and visual tokens: the drawer continues to use `--app-subtle`, existing selected-menu colors and the current dark-theme tokens.
+- Colors and visual tokens: dark sidebar surfaces and the selected green state remain unchanged. Popovers inherit the existing dark Naive UI theme.
-- Image quality and asset fidelity: no raster assets were added or altered. Menu and close actions use the project's existing Lucide icon package.
+- Image and asset fidelity: no raster assets were introduced. Existing Lucide menu icons are preserved.
-- Copy and content: brand, “我的剧本” and “后端连接” labels are unchanged.
+- Copy and content: PC hints use each menu's existing label. Locked entries append “（剧本完成后可用）”; “后端连接” keeps its original copy.
 
 ## Findings
 
 - No actionable P0/P1/P2 visual or responsive issues remain.
-- The disconnected local backend produces the expected in-page `502` status in the closed-state project list; it does not affect the navigation layout or interaction.
+- The disconnected local backend produces the expected in-page `502` response; it does not affect sidebar layout or popover behavior.
 
 ## Primary interactions tested
 
-- Opened the full-screen navigation from the new menu button.
+- Collapsed the PC sidebar and hovered an enabled menu icon; “我的剧本” appeared.
-- Closed the navigation from its internal close button.
+- Hovered the disabled “视觉风格” icon; its availability explanation appeared.
-- Confirmed the hidden navigation is removed from the accessibility tree with `aria-hidden` and `inert`.
+- Hovered the bottom settings icon; “后端连接” appeared.
-- Confirmed the closed-state main content width equals the mobile viewport width.
+- Clicked an enabled collapsed icon and confirmed navigation to the target workflow route.
-- Confirmed desktop behavior remains covered by the existing layout component tests.
+- Expanded the PC sidebar and confirmed menu popovers were absent.
+- Confirmed through component tests that mobile navigation does not render menu popovers.
 
 ## Console errors checked
 
-No application-origin console errors were reported. The cloud browser logged only its own extension metadata messages; these are outside the application.
+No application-origin console errors were reported. The cloud browser logged only extension metadata messages outside the application.
 
 ## Comparison history
 
-- Iteration 1: replaced the persistent mobile rail with a fixed full-screen navigation and added the menu/close icon pair.
+- Iteration 1: added native NPopover wrappers and found that the full-width transparent RouterLink intercepted hover on enabled menu icons.
-- Iteration 2: verified the open state at `543 × 936`, then closed it through the internal action and verified the content region expanded to the full `543px` viewport width.
+- Iteration 2: made enabled collapsed icons direct RouterLinks, raised their trigger layer above the transparent label and rechecked enabled, disabled and settings hints in the browser.
 
 ## Implementation checklist
 
-- [x] Hide the mobile navigation without reserving horizontal space.
+- [x] Add NPopover hints to all PC collapsed sidebar menu icons.
-- [x] Open navigation as a full-screen fixed layer.
+- [x] Preserve click navigation for enabled collapsed icons.
-- [x] Replace the top toggle glyph with a menu icon.
+- [x] Explain locked workflow items in their hint copy.
-- [x] Provide an internal close control while the top bar is covered.
+- [x] Keep PC expanded and mobile navigation free of duplicate popovers.
-- [x] Preserve automatic close on mobile route changes, settings open and Escape.
+- [x] Preserve sidebar size, spacing, theme and selected state.
-- [x] Preserve desktop collapse/expand behavior.
