"""Governance API contract tests using Schemathesis for OpenAPI compliance.

Validates that governance endpoints conform to their OpenAPI specification.
Uses property-based testing with Hypothesis to generate diverse test cases
and validate request/response schemas.

Contract test coverage:
- GET /api/agent-governance/rules - Get governance rules
- GET /api/agent-governance/agents - List agents with maturity
- GET /api/agent-governance/agents/{agent_id} - Get agent maturity
- GET /api/agent-governance/agents/{agent_id}/capabilities - Get agent capabilities
- POST /api/agent-governance/check-deployment - Check workflow deployment
- POST /api/agent-governance/feedback - Submit agent feedback
