63 A deliverable carries specifications, not its history

What people usually ask

Make the equipment list spreadsheet for the neutralization unit from my notes.

What comes back

A workbook with a column headed Reasoning, cell comments that read “assumed”, and a colour code nobody asked for.

Ask this instead

Make equipment_list.xlsx for the neutralization unit from the attached data. One sheet. Columns: tag, item, material, capacity, design pressure, design temperature, connection size. Numbers and short labels only. No sentence in any cell, no cell comments, no colour, no extra column.
Where the data gives no value, leave the cell empty.
Everything else goes in notes.md beside the workbook: each assumption with the cell it affects, where each value came from, and the open points as questions. One line each.
Print the sheet as a table and the first ten lines of notes.md, then stop.

Attach: The data as a table, or the notes it comes from.

Why it works: The sheet goes to the people who build from it, and the reasoning stays in a file that is opened when a value is questioned.
