WBS-7.3: GAS→Python 마이그레이션 4개 항목 추가 완료 (F15, F07, F14 재검증)

새로 완료된 항목: - F15: late_chase_gate 로직 포팅 * formulas/late_chase_gate_v1.py: is_late_chase_blocked() 구현 * tests/parity/test_late_chase_gate_parity_v1.py: 11 parity 테스트 (모두 PASS) * 두 가지 조건(explicit gate block OR risk score >= 70)을 정확히 포팅 - F07: score_thresholds 상수 모듈 추가 * formulas/score_thresholds_v1.py: SP_TAKE_PROFIT 등 17개 threshold 상수 * tests/parity/test_score_thresholds_parity_v1.py: 9 parity 테스트 (모두 PASS) * GAS THRESHOLDS 객체의 모든 값 정확히 재현 - F14 재검증: late_chase_risk_score는 GAS 유일 생산처 (Python canonical 없음) * migration_action: KEEP_IN_GAS로 확정, status: DONE 전체 테스트: 135/135 PASS 완료 현황 (총 15개 항목 중): ✅ DONE (9개): F01, F02, F03, F04, F06, F07, F09, F11, F14, F15 🔴 KEEP_IN_GAS (2개): F08, F14 🕐 TODO (4개): F05 (큰 함수), F10 (큰 함수), F12/F13 (아키텍처 결정 대기) 남은 작업: - F05/F10: 각각 100+줄 함수(calcExitSellAction_, routing)의 일부 → 다중 세션 포팅 필요 - F12/F13: KEEP_BOTH_SEPARATE_ROLES (아키텍처 결정 완료, 추가 코딩 불필요) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
