"""Shared pytest fixtures for the Agentic OS test suite.

The application code (``server.py``) computes a number of module-level path
constants from ``BASE_DIR`` at import time. To keep tests hermetic — no writes
to the real repository — the fixtures below redirect every one of those
constants at a temporary directory and rebuild the minimal folder layout the
endpoints expect.
