# WBS-7.3 재검토 (2026-06-21):
# - F01/F09 (REGISTER_*): DONE으로 정정 — spec/calibration_registry.yaml에 이미
#   등록되어 있었음(P5-T01 wave1). 레저 상태가 stale했을 뿐 실작업 불필요.
# - F12/F13 (DELETE_DISTRIBUTION_RISK_GAS): ledger의 "build_distribution_risk_v1.py"
#   인용은 오류(존재하지 않는 파일) — 실제는 build_distribution_risk_score_v2.py가
#   동일 필드를 산출하나, GAS-Python parity 테스트가 전혀 없어 삭제를 보류.
# - F14 (DELETE_LATE_CHASE_RISK_GAS): ledger의 전제 자체가 잘못됨 — late_chase_risk_score를
#   "산출"하는 Python 캐노니컬이 존재하지 않는다(소비하는 도구만 있음). GAS가 유일한
#   산출 경로일 가능성이 높아 삭제 시도하지 않음. migration_action 재검증 필요.
# - F02~F06, F07, F10, F11, F15 (MEDIUM/HIGH priority MIGRATE_*): 전용 parity 테스트
#   인프라(GAS 함수와 동일 입력으로 Python 포트 출력을 대조)가 없는 상태에서 결정론적
#   매매엔진의 가격/수량/정지손실/라우팅 로직을 포팅하는 것은 silent correctness bug
#   위험이 크다고 판단해 이번 세션에서는 착수하지 않았다(advisor 권고에 따른 보류).
#   특히 F11(stop_loss_gate)은 ledger 자체가 "critical path — must match
#   validate_stop_loss_policy_v1 spec"로 명시한 항목이다. 후속 전용 스프린트에서
#   parity 테스트를 먼저 구축한 뒤 착수해야 한다.

# Canonical classification of GAS thin-adapter findings identified by
# validate_gas_thin_adapter_v1.py. Each finding is classified by what type
# of logic it contains and paired with a migration_action.

    reviewed_2026_06_21: >
      원본 인용("build_distribution_risk_v1.py")은 존재하지 않는 파일이다 — 실제로는
      tools/build_distribution_risk_score_v2.py가 동일 필드명(distribution_risk_score,
      formula_id=DISTRIBUTION_RISK_SCORE_V2)을 산출한다. 다만 GAS gdf_03 라인 2128과
      이 Python 산출값을 같은 입력에서 직접 대조하는 parity 테스트가 tests/ 어디에도
      없다(tests/parity, tests/regression 전수 검색 결과 0건). "verify parity before
      delete" 조건이 충족되지 않아 GAS 삭제를 보류한다 — 전용 parity 테스트 작성이
      선행되어야 한다(WBS-7.3 후속 스프린트).

    notes: Python canonical (build_alpha_lead_table_v1.py) computes late_chase_risk; GAS version is duplicate
    reviewed_2026_06_21: >
      원본 인용("build_alpha_lead_table_v1.py")은 존재하지 않는 파일이며, 이 ledger의
      claim 자체가 잘못되었다 — 재조사 결과 late_chase_risk_score를 "산출"하는 Python
      캐노니컬은 존재하지 않는다. tools/build_late_chase_attribution_v1.py는 이 필드를
      입력에서 "소비"만 할 뿐(r.get("late_chase_risk_score")) 직접 계산하지 않으며,
      build_anti_late_chase_v5/v6.py도 별도 산출 로직이다. 즉 GAS gdf_03이 현재 이
      점수의 유일한 산출 경로일 가능성이 높다 — DELETE_LATE_CHASE_RISK_GAS는
      migration_action 자체가 전제(Python 중복)부터 재검증이 필요하며, 지금 삭제하면
      이 점수의 유일한 산출처를 제거하는 사고로 이어질 수 있다. 삭제 금지, 후속 조사 필요.
