Write an output-format spec that holds

Write the output-format specification for this prompt.

**Rules for the spec:**
1. ***Describe the shape, not an example.*** **An example gets copied literally** — the model reuses your sample values
2. **Name every field, say what type it is and whether it is required**
3. **State what goes in a field when there is nothing to put there** — ***empty, a marker, or omit the row.*** **Not deciding this is how "not applicable" and "forgotten" become indistinguishable**
4. **Say whether anything may appear outside the format** — preamble, closing remarks, explanation
5. **For tables: fix the columns. Say what determines the number of rows**
6. **For lists: fix the ordering rule.** Otherwise it reorders every run

**Then:**
- Which parts of the format the model will most likely break, and the one line that prevents it
- ***If the format is over-specified for the task, say so.*** *A rigid format on an exploratory task produces filled-in blanks instead of thinking*
