"""
Mobile API Agent Execution Tests

Tests for mobile API agent execution endpoints:
- Agent execution (sync and streaming)
- Agent execution with parameters
- Agent execution governance checks
- Agent execution history

All tests use API-first approach with TestClient (no browser).
Response structure matches web API for consistency.
