"""
Atomizer Validation System
==========================

Validates study configuration before optimization starts.

Components:
- ValidationGate: Main orchestrator for validation
- SpecChecker: Validates atomizer_spec.json
- TestTrialRunner: Runs 2-3 test trials to verify setup

Usage:
    from optimization_engine.validation import ValidationGate

    gate = ValidationGate(study_dir)
    result = gate.validate(run_test_trials=True)

    if result.passed:
        gate.approve()  # Start optimization
