Phase 0 from DASHBOARD_UI_COVERAGE_ROADMAP:
- Register ai-diagnostics routes in server.ts (671-line module was never mounted)
- Add 6 hidden pages to admin sidebar-nav.tsx:
Debug Sessions, Health Dashboard, Extraction, Experiments,
Predictive, AI Diagnostics
- /users was already in sidebar (no change needed)
- Kill switch verified: already per-product via productId query param
- Admin sidebar now has 33 items (was 27)
- New /actiontrail page with 4 tabs: Timeline, Agents, Alerts, Approvals
- Summary cards: total actions, critical/high count, pending approvals, active alerts
- Risk-level filtering on timeline, color-coded risk badges
- Server-side API proxy route (/api/actiontrail) to ActionTrail backend (port 4018)
- actiontrail-client.ts: typed API client using @bytelyst/api-client
- Sidebar nav item with Crosshair icon
- ACTIONTRAIL_SERVICE_URL added to .env.example
- Graceful fallback when ActionTrail service is unavailable
Removed unused local copies that were superseded by shared package imports:
- EmptyState.tsx (dead — no imports found)
- LoadingSpinner.tsx (dead — no imports found)
- PageHeader.tsx (dead — no imports found)
Dashboard already consumes NotFoundPage from @bytelyst/dashboard-components.
- product-config.ts: add getRequestProductId(req) helper + KNOWN_PRODUCTS list
- product-context.tsx: new React context storing selected productId in localStorage
- product-switcher.tsx: dropdown component with icons for all 4 products
- api.ts: pass x-product-id header from localStorage on all API calls
- providers.tsx: wrap with ProductProvider
- sidebar-nav.tsx: render ProductSwitcher between logo and nav
- repositories/users.ts + tokens.ts: accept optional productId parameter
- 8 API routes updated: users, auth/login, auth/forgot-password, seed,
settings/plans, themes/active, analytics/retention, analytics/revenue
