Set up a recurring weekly or monthly report

Who reads the report and what they decide with it: {{report_purpose}}
How often and when it goes out: {{frequency}}
Where I will build it: {{tool}}

The metrics I report or want to report, and where each comes from:
"""
{{metrics}}
"""

The data I refill it from, as column headers and a few sample rows:
"""
{{sample_data}}
"""

The current version of the report, if there is one:
"""
{{current_report}}
"""

Task: Design a fixed report structure that I refill with new numbers each period, so the report reads the same way every time and takes less effort to produce. The goal is that readers find the same thing in the same place each period and see at once what changed.

Deliver:
1. Report layout: the sections in order, each with its purpose in one line. It should fit on one page or one screen, with the three to five numbers that matter most at the top.
2. Metric definitions: a table with the columns Metric, Definition, Formula, Source columns, Compared with, Owner. Use only columns that exist in my sample data. If a metric cannot be calculated from them, say what is missing.
3. Commentary rules: when a movement deserves a sentence (for example, "comment on any change over 10% or any metric outside its target"), and a fill-in sentence pattern such as "[Metric] was [value], [up or down] [change] from [last period], because [reason from owner]".
4. Spreadsheet setup in {{tool}}: a tab where I paste the raw data each period, a tab that calculates, and the report tab, with what goes where. No numbers typed into formulas.
5. Refresh checklist: the numbered steps to produce the report each period, ending with a check that the totals match the source system before it goes out.

Requirements:
- Keep each metric from the current report unless it does not serve the readers' decisions, and list any you drop with the reason.
- Show "data as of" and the period on the report, so old numbers are never mistaken for new ones.
- Do not invent targets or thresholds. Where I have not given one, leave a labeled gap for me to fill.

Keep parts 1, 3 and 5 under 400 words in total. If my purpose or data is too vague to decide what belongs at the top, say so and ask the one question that would settle it.
