## Overview

GLOSA’s sampled runtime is a small user-authentication backend: clients can register, log in, and list users; the server uses MongoDB-backed user queries and falls back to in-memory users when database operations fail. The database connector initializes the MongoDB connection. The tree also contains an HTML client, but its contents and interactions were not sampled, so no client-to-API relationship is asserted.

Main entry points: [`server.js`](https://github.com/pavankumarnulakani46-cloud/pavan/blob/main/server.js) (Auth and user routes), [`db.js`](https://github.com/pavankumarnulakani46-cloud/pavan/blob/main/db.js) (MongoDB connector)

## Components

### User API

- [Auth and user routes](https://github.com/pavankumarnulakani46-cloud/pavan/blob/main/server.js): `server.js`

### User Storage

- [Fallback users](https://github.com/pavankumarnulakani46-cloud/pavan/blob/main/server.js): `server.js`
- [MongoDB connector](https://github.com/pavankumarnulakani46-cloud/pavan/blob/main/db.js): `db.js`

### Other components

- **API client**
- **MongoDB**

## Connections

- API client → Auth and user routes: requests
- Auth and user routes → Fallback users: reads and writes (evidence: `server.js`)
- Auth and user routes → MongoDB connector: initializes (evidence: `server.js`)
- MongoDB connector → MongoDB: connects (evidence: `db.js`)
- Auth and user routes → MongoDB: queries users (evidence: `server.js`)
