 ## Full-view comparison evidence
 
-The source crop shows four adjacent icon buttons with two different spacing values: the grid/masonry pair is tightly grouped while refresh and batch image have visibly larger gaps.
+The source crop shows the search and type controls on the first row, while the second row combines a wide status select with four icon buttons. The second row is visually crowded and leaves the controls competing for the same horizontal space.
 
-The implementation now places all four controls in one flex group with a shared `8px` gap. Grid, masonry, refresh, and batch image each use `NPopover`; all four popovers share the same responsive `disabled` state and are disabled at `max-width: 760px`.
+The mobile implementation now uses three explicit rows at container widths up to `460px`: full-width search, two equal-width selects, then a full-width right-aligned icon action row. The existing `10px` internal rhythm and icon ordering are preserved.
 
-A local Sites preview started successfully, but the cloud browser rejected `terminal.local` with `net::ERR_BLOCKED_BY_CLIENT` on both attempts. Therefore no browser-rendered implementation screenshot is available.

 ## Focused region comparison evidence
 
-- Control order: grid → masonry → refresh → batch image.
-- Spacing: all four controls are direct children of the same `gallery-layout-switch` flex group with `gap: 8px`.
-- Desktop explanations: all four controls use hover-triggered `NPopover` copy.
-- Mobile behavior: all four popovers bind `:disabled="isMobile"`; the media query follows `(max-width: 760px)`.
-- Accessibility: every icon-only button retains a stable Chinese `aria-label`; native `title` attributes were removed from the first two buttons.
+- Row 1: search spans both grid columns.
+- Row 2: subject type and image status use equal-width `minmax(0, 1fr)` columns.
+- Row 3: the four icon actions occupy the complete row and align to the right.
+- Spacing: both column and row gaps are `10px`.
+- Accessibility and behavior: filter labels, layout switching, refresh, batch action, and mobile-disabled popovers remain unchanged.
 
 These are code-level checks only and do not replace a rendered focused-region comparison.
 
 ## Required fidelity surfaces
 
-- Fonts and typography: no visible toolbar type styles changed; popover typography remains Naive UI-managed.
-- Spacing and layout rhythm: the four-button group now uses one uniform `8px` rhythm.
-- Colors and visual tokens: selected and unselected button colors are unchanged.
-- Image quality and asset fidelity: no image behavior changed.
-- Copy and content: desktop popovers explain `网格布局`, `瀑布流布局`, `刷新图库`, and `批量生图`; mobile keeps accessible names without hover overlays.
+- Fonts and typography: no typography or truncation rules changed.
+- Spacing and layout rhythm: mobile controls now follow a stable three-row grid instead of compressing the status select and actions together.
+- Colors and visual tokens: existing dark-theme surface and control tokens are unchanged.
+- Image quality and asset fidelity: no image behavior or assets changed.
+- Copy and content: all search, type, status, and icon action labels are preserved.
 
 ## Findings
 
 - [P1] Browser-rendered comparison unavailable
-    - Location: 形态图片筛选区的四个图标按钮。
-    - Evidence: the required cloud browser returns `net::ERR_BLOCKED_BY_CLIENT` for the healthy local preview on two attempts.
-    - Impact: exact pixel spacing, popover placement, hover visibility, responsive disabling, and console state cannot be visually certified.
-    - Fix: capture the page in an available browser at desktop and mobile widths and compare the four-button control group.

 ## Primary interactions tested
 
-Automated tests verify the exact four-button order, layout switching, refresh behavior, four desktop popover bindings, responsive disabled binding, accessible labels, and uniform generated `8px` CSS gap. All 275 tests pass. Browser hover and touch interaction were unavailable.

 ## Comparison history
 
-- Iteration 1: the source identified inconsistent spacing and missing explanations on the first two controls.
-- Iteration 2: consolidated all four controls into one spacing group, added popovers to grid and masonry, disabled all four popovers on mobile, and passed the full test/build suite. Browser capture remained blocked.
+- Iteration 1: the source identified crowding between the status filter and the four icon actions.
+- Iteration 2: separated mobile controls into search, equal filters, and action rows; the full test/build suite passed, while browser capture remained blocked.
 
 ## Implementation checklist
 
-- [x] Give all four icon buttons the same gap.
-- [x] Add `NPopover` explanations to grid and masonry.
-- [x] Disable all four `NPopover` components on mobile.
-- [x] Preserve accessible labels and existing button behavior.
-- [ ] Capture and compare desktop hover and mobile touch states in the cloud browser.
+- [x] Give mobile search the full first row.
+- [x] Give type and status filters equal widths on the second row.
+- [x] Move four icon actions to a dedicated right-aligned third row.
+- [x] Preserve existing filter and action behavior.
+- [ ] Capture and compare the rendered mobile state in the cloud browser.
