The feature ships with a test suite that validates four scenarios. The PRD lists seven requirements. The compliance review asks "which requirement is the encryption actually in scope for?" — and the answer is a spreadsheet cross-referenced by color, maintained by one person, last updated before the sprint began. Traceability does not scale as a spreadsheet; it scales as a diagram that *is* the trace.

**Quick answer:** document requirements traceability in Confluence as Mermaid `requirementDiagram`, rendered by [Mermaid Plus for Confluence](https://marketplace.atlassian.com/apps/1236814/mermaid-plus-diagrams-for-confluence/). Each requirement connects to the elements that satisfy and verify it — the gaps read at a glance, and the whole thing stays editable text next to the PRD. This post gives you three copy-paste examples: a feature trace, a compliance control, and an epic-to-test gap review.
