"""Harnais de fuzzing Atheris pour l'API.

Scorecard détecte le fuzzing Python par la présence de `import atheris`.
Ce harnais envoie des chemins et payloads aléatoires à l'application pour
débusquer des plantages non gérés (exceptions non attendues, 500).

Lancement local :
pip install atheris
python fuzz/fuzz_api.py
