"""
Test Data Factory Module for E2E UI Testing

This module provides reusable factory functions for generating test data across
different domains: users, agents, skills, projects, episodes, canvas, and chat.

All factories use unique_test_id (from worker_id + uuid4) for parallel execution safety.
Factories return dictionaries suitable for API requests or database initialization.

Key Design Principles:
- unique_test_id prevents parallel execution collisions
- Realistic default values (not "test1", "foo" placeholders)
- **kwargs support for field overrides
- Function-based (not class-based) for simplicity
- API-first design (dictionaries, not ORM instances)

Usage:
    from backend.tests.e2e_ui.fixtures.test_data_factory import user_factory, agent_factory

    # In a test with worker_id fixture
    user_data = user_factory(worker_id)
    agent_data = agent_factory(worker_id, maturity_level="AUTONOMOUS")
