# Mobile Chat UI Design QA

- Source visual truth: `C:/Users/Mirac/.codex/generated_images/01a0933f-6288-7ac1-b8e6-65be6c1a7207/exec-7abc19f1-940b-43f7-90ac-8edea31646ca.png`
- Implementation screenshot: `D:/mutli agent/.task-repair/chat-ui-mobile-final.png`
- Task drawer screenshot: `D:/mutli agent/.task-repair/chat-ui-drawer-final.png`
- Combined comparison: `D:/mutli agent/.task-repair/design-comparison.png`
- Viewport: Pixel 5 emulation, 393 x 727 CSS px, device scale factor 2.75
- Pixels: source 853 x 1844; implementation 1081 x 1999; drawer 1081 x 1999
- Normalization: source and implementation were each scaled to 390 x 844 and placed side by side in a 780 x 844 comparison image.
- State: existing completed task selected; task drawer tested open and closed.

## Full-view comparison evidence

The implementation matches the selected direction's conversation-first hierarchy: compact dark header, borderless assistant content, blue operator bubble, restrained inline task status, and pill composer. Real task text is substantially longer than the sample content, so the implementation preserves scrolling rather than truncating evidence.

## Focused interaction evidence

The task status row was opened in a real Chromium Pixel 5 session. The drawer showed populated stage, progress, last-update, log, and return controls. Menu open/close, task selection, drawer open/close, horizontal overflow, and browser console were checked. No relevant console errors were observed.

## Required fidelity surfaces

- Fonts and typography: system Chinese sans stack, compact header hierarchy, readable 15 px conversation text, restrained metadata.
- Spacing and layout rhythm: 16 px conversation gutters, 64 px compact header, 44 px minimum targets, safe-area-aware composer and drawer.
- Colors and visual tokens: near-black ground, low-contrast borders, limited blue accent, semantic green/error/gate tokens.
- Image and asset fidelity: the target contains no raster content. Remix Icon is used for UI icons; no placeholder imagery or handcrafted SVG/CSS drawings are used.
- Copy and content: existing real task, discussion, status, approval, recovery, and log copy is preserved.

## Comparison history

1. P1: mobile opened on the management list instead of chat. Fixed by making `show-main` the default and moving list access to the menu button. Browser navigation test updated and passed.
2. P2: task status disappeared when a long thread auto-scrolled to the bottom. Fixed by making the slim status trigger sticky inside the conversation.
3. P2: single-action composer was too tall. Fixed by placing the send action inside the right side of the composer shell.
4. Post-fix evidence: `chat-ui-mobile-final.png` and `chat-ui-drawer-final.png`; Pixel 5 interaction script completed with zero relevant console errors.

## Findings

No actionable P0, P1, or P2 differences remain. The real completed task has denser historical output than the illustrative source, which is expected product content rather than design drift.

## Follow-up polish

- P3: a future message-formatting pass could collapse very long historical review output behind a summary disclosure.

## Form controls follow-up

- Repository path remains a free-text input and now exposes server/history paths through a datalist.
- Codex and Claude model fields are selectable controls; selected models, effort values, repository path, and unsent task text survive reloads.
- The task description field has a larger editing surface and scrolls to the viewport center on focus.
- Browser matrix passed: iPhone 13 WebKit (390 x 664), Pixel 5 Chromium (393 x 727), iPhone 17 WebKit profile (402 x 874), and Galaxy S26 Ultra Chromium profile (412 x 915).
- Each profile was also reduced to a 430 px keyboard viewport; the focused task description remained fully visible with no horizontal overflow or console errors.

final result: passed
