# KOC LOOP 用户管理页设计 QA

- Source visual truth: `/var/folders/0g/8yrmts9s7v5g_xc60sxx0__80000gn/T/codex-clipboard-d06a2293-9e7d-4471-b4ae-5eee942b68e9.png`
- Implementation screenshot: `/private/tmp/koc-user-management-final.jpg`
- Delete confirmation screenshot: `/private/tmp/koc-user-delete-modal.jpg`
- Viewport: desktop `1280 × 720` CSS px; responsive check `680 × 900` CSS px
- Pixels and density: source `2738 × 1382`; implementation `1280 × 720`; browser reported `devicePixelRatio = 2`; comparison used the visible layout and computed CSS geometry rather than pixel-perfect scaling because the requested result intentionally changes the source from side-by-side to stacked sections.
- State: logged-in super administrator on the user-management screen

## Full-view comparison evidence

The source places account creation and the account list side by side, forcing a tall narrow form and compressing the list. The implementation intentionally stacks the sections: the account-creation card spans the page and uses one compact horizontal row on desktop; the account list spans the full row below it. Existing KOC LOOP navigation, typography, colors, border treatment, and panel radius remain unchanged.

## Focused-region comparison evidence

The delete confirmation modal was checked separately. It uses the existing modal shell, a restrained destructive color, explicit irreversible-action copy, cancel and confirm actions, and a disabled working state. No new image assets are present on this screen.

## Required fidelity surfaces

- Fonts and typography: existing product font stack, heading hierarchy, weights, and field labels are preserved; passed.
- Spacing and layout rhythm: panel padding, 16 px vertical section gap, 12 px form gap, and 14 px table rows establish a clearer rhythm; passed after responsive overflow fix.
- Colors and visual tokens: existing green, canvas, line, and panel tokens are preserved; destructive actions use a muted red semantic treatment; passed.
- Image quality and asset fidelity: this screen has no content imagery or custom visual assets; not applicable.
- Copy and content: creation, reset, and deletion copy is concise; deletion clearly states immediate sign-out and irreversibility; passed.

## Interaction verification

- Created a local ordinary test account.
- Opened the row-level delete confirmation.
- Confirmed deletion and verified the row disappeared.
- Verified the current super-administrator row has no delete action.
- Verified browser console errors: none.
- Verified desktop page horizontal overflow: none (`scrollWidth = innerWidth = 1280`).
- Verified 680 px responsive page horizontal overflow: none (`scrollWidth = innerWidth = 680`); the table scrolls inside its own container.

## Comparison history

1. Initial responsive pass found the account table's minimum width expanding the parent grid at 680 px.
2. Added `min-width: 0` to the stacked layout and panels, and constrained the table to its panel.
3. Post-fix evidence: page `scrollWidth` reduced from `714` to `680`, matching the viewport; the table retains an internal `660` px scroll surface.

## Findings

No actionable P0, P1, or P2 issues remain.

## Follow-up polish

No blocking polish items. A future iteration may add search when the account count grows substantially.

final result: passed
