# tests/integration/middleware/test_store_context_flow.py
"""
Integration tests for store context detection end-to-end flow.

These tests verify that store detection works correctly through real HTTP requests
for all routing modes: subdomain, custom domain, and path-based.

Note: These tests require the middleware conftest.py which patches:
1. get_db in middleware modules to use the test database session
2. settings.platform_domain to use 'platform.com' for testing subdomain detection
