+
+## Architecture overview
+
+The GitJet repository appears to be a web application built using Python and Flask. The main components of the application are as follows:
+
+- **Frontend:** The frontend is built using HTML, CSS, and JavaScript. It uses Bootstrap for styling and jQuery for interactivity.
+- **Backend:** The backend is implemented in Python using the Flask framework. It communicates with a database to store user data and retrieve information about repositories.

+
+## Use cases
+
+The following are the main use cases for the GitJet application:
+
+1. **Search repositories:** Users can search for repositories based on keywords or filters. This is triggered by a REST API endpoint `/search`. The components involved in this use case are the frontend, backend, and database.
+2. **View repository details:** Users can view detailed information about a specific repository, including its name, description, stars, forks, and contributors. This is triggered by a REST API endpoint `/repository/{id}`. The components involved in this use case are the frontend, backend, and database.
+3. **View user profile:** Users can view their own profile or other users' profiles. this is triggered by a REST API endpoint `/user/{username}`. The components involved in this use case are the frontend, backend, and database.

+```
+
+## Data and persistence
+
+The application uses a SQLite database to store user data, repository information, and search history. The database schema is as follows:
+
+- **User:** id (integer, primary key), username (string), email (string), password_hash (string)
+- **Repository:** id (integer, primary key), name (string), description (text), stars (integer), forks (integer), owner_id (integer, foreign key to User.id)
+
+## Observability and operations
+
+The application does not have any built-in observability or logging features. However, it can be configured to log important events such as database queries, API requests, and errors using a popular logging library like Python's `logging` module.
+
+## Security surface (auth, secrets touchpoints — factual only)
+
+The application uses basic HTTP authentication for user login. The password is hashed using the `bcrypt` algorithm before being stored in the database. The application does not use any third-party libraries or services for managing user sessions or tokens.
+
+In terms of security touchpoints, the following are relevant:
+
+- **Authentication:** Basic HTTP authentication is used to protect sensitive routes such as `/search`, `/repository/{id}`, and `/user/{username}`.
+- **Password hashing:** The passwords are hashed using the `bcrypt` algorithm before being stored in the database. This provides a layer of security against plaintext passwords.
