Reasoning
**Clarifying validation requirements**

I notice there's no applicable row for July 2025, so I should clarify before proceeding with any validation deductions. It seems structurally valid if we consider the largest cap. I need to ensure the JSON fields are exact; having clauses with an optional explanation would be helpful. Maybe I should include a short explanation addressing the unresolved blocker and asking for a resolution. The relevant clauses likely include "R1" and "R7."
