"""Phase Z-2 zone_ratio_retry action v0 (A3 — 실제 zone redistribution 구현).
router 가 *제안* 한 zone_ratio_retry action 의 **실행 layer**.
원칙 (A3 locked rules — 사용자 잠금 7+1) :
1. retry budget = 1 — 한 번만 시도
2. slide / slide-body / title / divider / footer / zone gap 모두 고정
(공통 spacing 깎기 금지)
3. 조정 대상 = router 가 지목한 *target zone* 만 height 증가
4. donor 선택 기준 :
- 같은 layout 의 sibling zone
- visual_check 통과 (이 zone 자체엔 overflow 없음)
- capacity_fit 가 ok
- 현재 height > min_height_px (slack > 0)
- donor min_height_px 아래로 줄지 X
- 여러 후보면 slack 가장 큰 것부터 (greedy)
- 부족 시 retry 실패
5. target_added_px = observed excess_y + safety_margin (small fixed)
— donor 가 min_height 아래로 가면 실패
6. retry 후 status :
- 성공 → PASS 가능
- 실패 → RENDERED_WITH_VISUAL_REGRESSION 유지 (CSS/padding/tolerance 보정 X)
7. debug trace 필수 (retry_attempted / target / donor / before/after / passed / reason)
8. revert 정책 ((b)) :
- redistribution check 실패 → rerender 안 함, original final.html 유지
- rerender 후 visual_check 실패 → original 로 revert (final.html 변경 X),
retried_candidate.html 은 *진단 artifact* 로만 별도 보관
- retry 성공 시에만 final.html = retried version
본 module 은 *plan + apply layer*. rerender / final.html 갱신 / revert 는 pipeline 이.
