docs: Phase 125 P2-P5 feedback (boxification review)
Feedback summary:
- 単一責任: EnvLayout / lower_return_value
- SSOT: reads ∩ available_inputs
- Fail-Fast: 構造化エラー + hint
- 段階的投入: 構造のみ（P3 で完成）
Good:
- Single responsibility principle maintained
- SSOT approach for env layout
- Fail-Fast with structured errors
- Graceful degradation (Ok(None))
Improvement proposals:
- P3 wiring clarification
- EnvLayout responsibility scope
- Error hint context-awareness
- Fixture completeness after P3
Next: Phase 125 P3 (available_inputs wiring)
