P4 Cascade Benchmark Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 동일 제품 brief를 3-arm(P1+P2 / P3-A / P3-B-active)으로 실행·비교해 P1~P3 개선의 품질 효과를 측정하는 캐스케이드 벤치마크 ruler + 1회 파일럿 인프라를 만든다.

Architecture: controller(정본 입력 + 수집 출력) · git worktree(arm 코드/하네스, clean 유지) · external workspace(brief·원장·산출물) 3분리. controller CLI(.claude/hooks/benchmark_cascade.py)가 bench_cascade/ 패키지의 focused 모듈(paths·inputs·manifest·budget·meter·sanitize·aggregate·judge·calibrate·compare·plan·runner·probe)을 dispatch한다. 품질 판정은 blinded paired pairwise 패널(제품만 봄), 프로세스 비용은 meter(실행 transcript 파생)로 완전 분리한다.

Tech Stack: Python 3(stdlib + PyYAML, 기존 hook과 동일) · git worktree · headless claude CLI(ORGOS_BENCH_CLAUDE 로 지정) · preview_ui.py(headless chrome 렌더). 테스트는 저장소 관례(standalone check() + sys.exit, run_all.py 자동 발견).

Global Constraints

• Blocker 1 — 외부 조사 봉인: benchmark-policy.external-web-access: denied, 전 arm 동일 evidence-pack(sha256 동일). 외부 검색 호출 발생 시 파일럿 실패.
• Blocker 2 — HUMAN gate 동일 정책: benchmark-human-policy(pre-authorized-for-benchmark) receipt를 전 arm 동일 적용. 몰래 자동승인 금지. forbidden: [external-side-effect, deployment, real-purchase, account-change, prod-resource-create]. meter에 human-interventions: {interactive, pre-authorized-receipts} 기록.
• Blocker 3 — 결정론적 sanitizer + 렌더: sanitizer는 규칙 기반(LLM 요약 금지). candidate는 candidate.yaml+prototype-desktop.png+prototype-mobile.png+prototype-manifest.json+substantive-excerpts.md 번들. 렌더 없거나 judge 이미지 미지원 시 design-distinctiveness = not-evaluable.
• Blocker 4 — 전 유료호출 예산 게이트: arm-run·calibrate·judge·retry·(LLM쓰면)sanitize 모두 approve-budget receipt 필요. receipt 없이 calibrate/judge 실행 거부. plan 비용 = calibration 호출 + 파일럿 18 + 최대 retry.
• judge 호출 수 = 3 pair × 3 paired judge × 2 orientation = 18(고정).
• 집계 수학: preference-score = (wins + 0.5×ties) / valid_stable_votes. panel-agreement = 최빈 verdict 수 / stable vote 수. position-flip-consistency = flip 일치 paired judge 수 / 전체 paired judge 수. 원시 개수 항상 병기.
• 패널 판정: stable vote < 2 → unstable · 최빈 verdict < 2표 → unstable · 최빈 ≥ 2표 → 채택.
• calibration PASS: 비교별 panel-agreement ≥ 2/3 & flip ≥ 2/3 · 집합 agreement ≥ 0.75 & flip ≥ 0.80 · Gold-vs-Bad: verdict=Gold & Gold preference ≥ 0.67 & 비교별 flip ≥ 2/3 · 단일결함 thresholds(rubric 0~4): target-min-drop 1.0, non-target-max-drop 0.5, target-margin-over-next 0.5, pairwise-target-goldwin-min 0.67. FAIL → judge 기본 차단(강제는 --allow-uncalibrated, 리포트에 UNCALIBRATED 스탬프).
• error = data: 실행 실패·gate-block·timeout은 meter 지표로 기록(숨김 금지). 실행 실패 arm은 canonical candidate 없음 → 품질 pairwise 제외. 파일럿 arm별 1회 → 한 arm 실패 시 전체 품질 순위 판정 보류(실패 arm 제외하고 승자 선언 금지).
• dedup: logical-vote-id = sha256(run-id|pair-id|judge-index|orientation), judgment-id = sha256(logical-vote-id|attempt). 집계는 같은 logical-vote-id에서 마지막 성공 유효본 1개만. malformed 2회째 실패 → panel-incomplete.
• arm commit(full hash pin): A=72997e5a65724f9d74efabcd41217acc3d0ce62e, B=dfb047587aac506aa5a59fce86d5d5eb39a5570f, C=353f1c6afe963b58939a198505d96c144ca6a583.
• 강제 disclaimer(최종 리포트): "이 파일럿은 ruler의 판별력, arm 격리, 실행 드라이버와 P1~P3의 잠정적 품질 신호를 검증한다. Arm별 단일 실행이므로 통계적 우월성이나 일반적인 생산성 향상을 확정하지 않는다."
• 정직: 데이터 없으면 "미실행" 표시(위장 없음).
• 테스트 실행 규약: CLAUDE_PROJECT_DIR="$PWD" ORGOS_WORKSPACE=_sandbox python3 .claude/tests/<file>.py. ROOT = os.environ.get("CLAUDE_PROJECT_DIR", os.getcwd()). standalone check(name, ok) + sys.exit(1 if failed else 0).

의존 순서: probe(Task 1, 스파이크) → paths(2) → inputs(3) → manifest(4) → budget(5) → meter(6) → sanitize-core(7) → sanitize-render(8) → aggregate(9) → judge(10) → calibrate(11) → compare(12) → planner(13) → runner(14) → CLI(15) → content(16).

핵심 원칙(shape 의존성): sanitize/meter/runner는 캐스케이드 아티팩트의 실제 shape에 의존한다. 이 plan은 test fixtures/p4/에 대표 shape를 계약으로 정의하고 그에 대해 TDD한다. Task 1(Phase 0 probe)의 실제 실행이 진짜 shape가 이 계약과 일치함을 확인/조정한다(계약-우선 TDD).

# Brief: "ShiftDeck" — 소규모 팀 교대근무 관리 웹 도구

## 문제
5~30인 매장/카페 매니저가 주간 교대표를 엑셀로 만들며 (1) 가용시간 충돌, (2) 야간 편중,
(3) 변경 공지 누락으로 반복 실수한다.

## 사용자 · 핵심 과제
- 1차: 매장 매니저(주 1회 교대표 작성·게시).
- 핵심 과제: 직원 가용시간 입력 → 충돌 없는 주간표 생성 → 변경 시 알림.

## 범위(파일럿)
- 단일 화면 우선(주간 교대 보드) + 직원 가용시간 입력.
- 결제·다점포·모바일앱 제외.

## 제약
- 웹(반응형), 오프라인 우선 아님. 접근성 AA. i18n 불필요(단일 로케일).
- 외부 조사는 evidence-pack 만 사용(외부 웹 금지).

1. Spec coverage:

• §3 3분리 → T2(paths)·T14(runner). §3a git 정책 → T2. §4.1 manifest+pre-flight+drift → T4. §4.2 입력 주입+hash → T3·T14. §4.2a evidence-pack+web denied(Blocker1) → T14·T16. §4.3 10-step stage 격리 → T14. §4.3.0 Phase 0 probe → T1·T14. §4.3a HUMAN receipt(Blocker2) → T14. §4.4 meter → T6. §4.5 sanitizer projection+렌더(Blocker3) → T7·T8. §4.6 judge 18-call+injection+집계 → T9·T10·T12. §4.7 calibration → T11. §4.8 budget(Blocker4) → T5·T15. §4.9 compare 4축+held → T12. §5 dedup+재현성 → T10. §6 CLI → T15. §10 테스트 → 각 태스크. §11 disclaimer → T12.
• 갭 없음. 12 테스트 항목(§10) 전부 대응: worktree clean(T14)·controller output 격리(T2 경로·T14)·evidence-pack hash 동일(T3·T16)·외부검색→실패(T14 env·T16 policy)·HUMAN receipt 동일(T14)·process 재개(T1)·projection↔hash(T7)·substantive 누락 fail(T7)·렌더없으면 미평가(T8)·예산 receipt 없이 거부(T5·T15)·총비용 calibration+retry(T13)·injection 불수행(T10)·resolved≠manifest→arm C 실패(T4).

2. Placeholder scan: 콘텐츠(T16 evidence-pack 본문, gold/bad candidate 본문)는 "≥N줄 고정 스냅샷/스키마 준수 샘플"로 구조를 명시 — 실제 문안은 저자가 채우되 스키마·최소길이가 계약. probe.run_probe 는 T1에서 시그니처만·T14에서 배선(명시적 순서 의존). 그 외 모든 코드 스텝은 완전 코드.

3. Type consistency: candidate-package 스키마(T7 CANON_FIELDS)를 T8·T12·T16이 동일 참조. logical_vote_id/judgment_id(T10)를 dedup·compare가 동일 사용. preference_score/panel_verdict(T9)를 compare(T12)가 재사용. manifest.preflight(T4)를 planner(T13)가 재사용. budget.require(T5)를 CLI(T15)·judge(T10)가 재사용. 불일치 없음.
