## Overview

SecureApp is a small FastAPI item API and a DevSecOps pipeline demonstrator. A client calls the API’s health and item endpoints; Pydantic validates item input, while the CRUD handlers read and write an in-memory store. The README documents a GitHub Actions pipeline for linting, tests, Python security audits, Docker builds, and Trivy image scans. Pipeline details are based on the README; the workflow and Dockerfile contents were not sampled.

Main entry points: [`.github/workflows/ci-cd.yml`](https://github.com/pierre-mzuafo/secureapp/blob/main/.github/workflows/ci-cd.yml) (CI workflow), [`app/main.py`](https://github.com/pierre-mzuafo/secureapp/blob/main/app/main.py) (FastAPI app), [`Dockerfile`](https://github.com/pierre-mzuafo/secureapp/blob/main/Dockerfile) (Docker build)
