## Overview

#### Purpose and Runtime
Hostel Food Management System is a React/Vite client for student, kitchen-supervisor, and admin meal operations: meal intent and physical attendance, leave handling, dashboards, profiles, and user management. A Node/Express server also exists, while Firebase Auth and Firestore are the stated identity/data backbone. Key entry points: `client/src/main.tsx`, `client/src/App.tsx`, `server/index.ts`.

#### Client Application Shell and Routing
`App.tsx` is the likely composition root for page routing, global providers, and role-specific navigation. The authenticated application shell is separated into layout primitives, allowing pages to share sidebar/top-bar structure. Public authentication pages are distinct from operational routes.
Paths: `client/src/App.tsx`, `client/src/components/layout/Layout.tsx`, `client/src/components/auth/PrivateRoute.tsx`.

#### Identity, Authorization, and User Roles
Firebase authentication is encapsulated through an auth context and supporting Firebase modules. `PrivateRoute` forms the client-side access boundary; role-based dashboards and administration pages indicate at least student, kitchen, and admin experiences. Firestore rules provide the server-enforced authorization boundary.
Paths: `client/src/contexts/AuthContext.tsx`, `client/src/firebase/auth.ts`, `firestore.rules`.

#### Role-Specific Operations and Dashboards
Dashboard pages split views by operating role: admins oversee users and system-level status, kitchen users manage food-facing workflow, and students manage their own participation. Reusable cards present attendance trends, meal status, risk/activity, and AI-verification-oriented indicators.
Paths: `client/src/pages/dashboard/AdminDashboard.tsx`, `client/src/pages/dashboard/KitchenDashboard.tsx`, `client/src/pages/dashboard/StudentDashboard.tsx`.

#### Dual Meal Attendance Flow
The central business flow is two-stage meal participation: students submit a meal preference/intention in advance, then attendance is recorded at the meal. Attendance tracking and meal tracking pages orchestrate these workflows; dedicated hooks mediate their data access. This is the principal boundary between planning demand and confirming food service.
Paths: `client/src/components/attendance/MealPreferenceForm.tsx`, `client/src/components/attendance/MealAttendanceMarker.tsx`, `client/src/hooks/useAttendance.js`.

#### Leave and Student Profile Flow
Students can submit leave requests, while management users review them. Student records/profile views supply an adjacent identity and operational context, likely used for attendance, leave, and administration.
Paths: `client/src/pages/leave/LeaveRequestPage.tsx`, `client/src/pages/leave/LeaveManagement.tsx`, `client/src/pages/profile/ProfilePage.tsx`.

#### Data and Backend Boundaries
Firebase configuration modules connect the browser to Firebase Auth/Firestore, with Firestore indexes supporting query patterns. The repository additionally has an Express server with route, storage, and database abstractions, plus a shared schema—suggesting a parallel or transitional server-backed API/data path. Engineers should establish which path is authoritative before extending domain features.
Paths: `client/src/firebase/config.ts`, `server/routes.ts`, `shared/schema.ts`.

#### Infrastructure
The main runtime is TypeScript React on Vite, styled with Tailwind. Firebase deployment/configuration and Firestore policy/index definitions are committed at the root. Node/Express is available for backend execution; Drizzle configuration and server database modules indicate potential relational persistence integration.
Paths: `vite.config.ts`, `firebase.json`, `server/db.ts`.
