## Overview

#### Purpose and Entry Points
This repository is a Django backend exposing a REST API for a TF-IDF-based chatbot. The process starts through `manage.py`, with deployment interfaces in `DjangoReactChatbot/wsgi.py` and `DjangoReactChatbot/asgi.py`. URL routing begins at `DjangoReactChatbot/urls.py`.

#### Django Project Runtime
`DjangoReactChatbot/settings.py` defines the Django runtime, installed applications, middleware, database, and API-related settings. The repository includes a SQLite database snapshot at `db.sqlite3`, so persistence is local rather than an externally managed database service.

#### API Application Boundary
The `api` Django app owns chatbot-facing API behavior and persistence concerns. It is registered through `api/apps.py`; project-level routes delegate into app routes via `DjangoReactChatbot/urls.py` and `api/urls.py`.

#### Request-to-Response Flow
A client calls an endpoint defined in `api/urls.py`. Django dispatches the request to handlers in `api/views.py`, where chatbot/API control flow is implemented. Views use serializers and models as needed, then return Django/REST-style HTTP responses to the caller.

#### Chatbot Processing Layer
The stated product behavior is a TF-IDF chatbot API. Its request interpretation and answer-generation integration are expected to be centered in `api/views.py`; no separately visible ML model package, corpus, model artifact, or external inference service appears in the repository tree. This makes the API view layer the key boundary between HTTP input and chatbot logic.

#### Data Contract and Persistence
`api/serializers.py` defines translation and validation between request/response payloads and Django model objects. `api/models.py` defines durable application data, with schema initialization captured in `api/migrations/0001_initial.py`. Django ORM operations provide the boundary between API logic and SQLite.

#### Infrastructure and Deployment Interfaces
The application supports both synchronous WSGI and asynchronous ASGI hosting through `DjangoReactChatbot/wsgi.py` and `DjangoReactChatbot/asgi.py`. There is no evidence of a separate React frontend, message queue, cache, cloud service, authentication provider, or externally hosted ML runtime in the supplied tree.
