Extracted inline SteeringControls from LivePage into standalone component.
Added Fork button (modal to clone experiment config), Export Best dropdown
(JSON/YAML/.env download), and estimated time remaining stat. LivePage
updated to import the new component. 33 tests added, all 284 tests pass.
Extract the inline LeaderboardTable from LivePage into a standalone
Leaderboard component with click-to-expand detail rows, sortable
columns, smooth slide-in animation for new entries, and a subtle
glow effect on the best run. 29 tests added.
Full LivePage implementation with 60/40 split layout:
- Left column: Activity Timeline with color-coded event cards (run.started, run.completed, new_best_found, cache_hit, run.failed), event type filtering, and auto-scroll toggle
- Right column: Leaderboard table with sortable columns, best-run highlighting, and status badges; Steering Controls with pause/resume/stop (with confirmation dialogs), progress bar, token counter, cost estimate, and cache hit rate
- WebSocket integration with exponential backoff reconnect, connection status indicator, and experiment subscription
- 35 tests covering loading/error states, WebSocket events, timeline filtering, leaderboard updates, progress tracking, and steering control interactions
Add SetupPage, LoginPage, DashboardPage, ProjectsPage, ExperimentPage, LivePage,
ComparePage, and AdminPage as placeholder components. Wire up react-router-dom routing
in App.tsx with BrowserRouter in main.tsx. Unknown routes redirect to dashboard.
Install vitest + @testing-library/react and add 9 routing tests. Build passes cleanly.
