"""
Custom route-to-scope mappings
==============================
Override selected entries in the default AgentOS scope map and add a second
application scope to agent runs. The smoke proves the override on GET /config.
Prerequisites: none for the smoke; OPENAI_API_KEY for live agent runs
Run: .venvs/demo/bin/python cookbook/05_agent_os/07_security/custom_scope_mappings.py
Try: call GET /config with an app:read token
