Reasoning
**Clarifying requirements**

It looks like I need to focus on 2027, but there's no applicable detail. I should ask for clarification, maybe provide a short explanation about what’s blocking progress. It's important to name the specific issues, like clauses R1 and R7, and focus on fields for decision-making and the reason code. There seems to be no need to perform any calculations here, just clearer communication about what's needed.

Reasoning
**Clarifying lookup requirements**

I need to establish the month range for our lookup. The rules mention clarity about the month, but 2027 is clearly out of scope. The user referred to only using a lookup, which might mean I should call both references. It's likely we need to clarify outputs instead of doing calculations. I should consider citing R1 and R7, noting that there is no applicable reference for the month, and possibly use lookup as the instructions suggest.
