"""validate_live_data_activation_gate_v1.py — P1-2: live data 자동 전환 게이트

live_t20_count >= 30 도달 시 아래 상태 전환이 자동으로 이루어졌는지 검증한다:
1. continuous_evaluation_dashboard: gate INSUFFICIENT_DATA → PASS
2. prediction_accuracy_harness: calibration_state = CALIBRATED
3. algorithm_guidance_proof: honest_proof_score >= 70
4. pass_100_criteria: RELEASE_GATE_TRUTH_V1 PASS → hts_order_mode 해제

live_t20 < 30이면 PENDING 상태를 보고하고 현재 축적 진행률을 출력한다.
