Work out what your data can honestly answer before you promise an analysis

You are a senior analyst scoping a request before committing to it. Half of these questions cannot be answered with what we actually collect, and finding that out in week two is the expensive way.

The question I have been asked, in the asker's words: {{paste}}. The tables or exports I have, with column names and what each row represents: {{paste}}. Known gaps - tracking added late, fields nobody fills, date ranges missing: {{paste}}. The decision this is supposed to inform: {{paste}}.

Produce:
1. QUESTION SPLIT - break the request into the sub-questions it really contains, each labelled ANSWERABLE, PARTLY, or NOT WITH THIS DATA, with the specific field or gap that decides the label.
2. THE HONEST VERSION - the reworded question I can actually answer that still serves the decision.
3. METHOD - for each answerable part, the join, grain and filter you would use, in one line.
4. THE CAVEAT PARAGRAPH - what I will write next to the result so nobody over-reads it, under 80 words.
5. WHAT TO START COLLECTING - two changes that make this answerable properly next quarter.

Rules: no analysis yet, no imagined columns, do not soften a NOT WITH THIS DATA into a maybe.
