[MetaROR] Ch10 Checklist — author revisions

Author revisions for **Chapter 10 (Checklist)** from the MetaROR reviews (R1).

- [x] Reconsider the checklist format — items are currently high-level recommendations rather than concrete checklist items. (R1) (in #43)

**Handled in other issues:**
- Move the checklist to an Appendix and discuss it in a conclusion section rather than its own Part → *Structural reorganisation & scope*

Start by reading the Chapter 10 (Checklist) content and issue #43, where the remaining checklist-format revision is noted as being handled. Confirm whether any work remains in this issue; it is done when the Chapter 10 revision is accounted for elsewhere or the remaining change is clearly tracked in the appropriate issue.
