# T04: Created OutputInfoBar with color-coded stats, wired Use This button with disabled state, added 7 component tests — 23/23 tests pass, zero TS errors
**Created OutputInfoBar with color-coded stats, wired Use This button with disabled state, added 7 component tests — 23/23 tests pass, zero TS errors**
## What Happened
Built the OutputInfoBar component displaying trace metadata (Path Count, Total Nodes, Open Paths, Processing Time) with color-coded indicators: green for normal values, yellow when node_count_total > 5000, red when open_paths > 0. Null metadata shows a muted placeholder. Warnings render below the stats. Updated ImportConvert to render OutputInfoBar below the preview and changed the Use This button to always-visible with disabled state (disabled when no SVG output or loading). Added CSS for the info bar. Wrote 7 tests covering all color coding thresholds and edge cases. Verified empty/error/loading states from T03's SvgPreview remain correct.
## Verification
npx tsc --noEmit: zero errors. npx vitest run --reporter=verbose: 23/23 tests pass across 3 test files (9 API client, 7 OutputInfoBar, 7 useDebouncedTrace).
## Verification Evidence
| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd app && npx tsc --noEmit` | 0 | ✅ pass | 6400ms |
| 2 | `cd app && npx vitest run --reporter=verbose` | 0 | ✅ pass | 2500ms |
## Deviations
Use This button changed from conditionally rendered to always-visible with disabled attribute — better UX (no layout shift). Empty/error/loading states already complete from T03.
## Known Issues
None.
## Files Created/Modified
- `app/src/components/OutputInfoBar.tsx`
- `app/src/components/__tests__/OutputInfoBar.test.tsx`
- `app/src/views/ImportConvert.tsx`
- `app/src/App.css`
## Deviations

Add 'Use This' button to `ImportConvert.tsx`:\n - Disabled when no SVG output is available\n - On click: call `onUseThis(svgOutput, metadata)` prop, which App.tsx uses to transition view state to 'canvas'\n - Pass the SVG string forward (stored in App.tsx state for S02 to consume)\n3. Add empty/error states throughout:\n - No file selected: show upload prompt in preview area\n - API error: show error message in preview area with status code\n - Loading: show spinner overlay on preview\n4. Write `app/src/components/__tests__/OutputInfoBar.test.tsx` — test color coding logic:\n - Normal metadata → green indicators\n - High node count → yellow indicator\n - Open paths > 0 → red indicator\n - Null metadata → no crash, placeholder shown\n5. Final verification: ensure `npx tsc --noEmit` passes with zero errors, `npx vitest run` passes all tests, and all components are wired together end-to-end.",
