M1 — Single SessionProvider via nested router. The previous router had two route entries with `path: '/'` (Navigate, AppShell) plus a separate `/login` entry, each wrapped in its own RootLayout. That instantiated SessionProvider three times, forking state the moment session writes diverged across siblings. Replaced by one Root route with SessionProvider + <Outlet />, and index/login/AppShell-children nested underneath. RootLayout (the per-tree wrapper) is now obsolete and deleted; the new Root component lives in src/routing/Root.tsx (addresses NIT N4 as a side effect). M2 — Typo: "pollign" → "polling" in LiveCockpitPage masthead. M3 — Replace asymmetric `?? 'rt_operator'` / `?? 'soc_analyst'` fallbacks in LiveCockpitPage with an explicit `if (!user) return null;` guard placed after all hooks (rules-of-hooks). AppShell already redirects unauthenticated visitors to /login, so the guard documents the invariant rather than introducing one. NITs N1-N3, N5-N7 recorded in tasks/todo.md as sprint 1+ follow-ups.
Mimic frontend
React + TypeScript SPA for the Mimic BAS platform. Lives behind the existing RT reverse proxy (Caddy + TLS + IP allowlist) — see D-007.
Stack
- React 19, TypeScript strict
- Vite 8 (dev/build)
- Tailwind 4 (semantic tokens in
src/styles/theme.css) - TanStack Query 5 for server state
- react-router-dom v7 for routing
- Recharts for the report visualisations
- Vitest + Testing Library for unit tests
- Playwright for E2E (covered in sprint 1+)

Design system status (provisional)
The token layer in src/styles/theme.css is structured to receive the RT
graphic charter (PR3) without touching component code. Component CSS reads
exclusively from semantic tokens (--accent-rt, --status-detected, …);
swapping the underlying primitive palette is the only change required when
PR3 lands.
Auth status (sprint 0)
The session context reads/writes a mock user in sessionStorage. No real
auth yet. v1 will wire local username/password + bcrypt (D-003); v2 maps
Keycloak OIDC claims onto the same role enum.
Fonts
IBM Plex (Sans / Sans Condensed / Mono), self-hosted under public/fonts/.
Files are not yet vendored — see public/fonts/README.md. Until then the
UI falls back to ui-sans-serif / ui-monospace.
