# A researched brief a writer can use

This packet shows one question moving from real search-result observations to a bounded writing assignment. The selected question is **“When should I update a page's sitemap lastmod date?”** It was chosen for the demonstration; no search volume, customer demand or ranking opportunity has been established.

The research was performed on **October 6, 2026**, starting at **15:51:31 UTC**. The page-change cases are explicitly fictional. The resulting brief is an assignment, not a published sitemap article or evidence of SEO results.

1. [Result observations](result-observations.md): what was actually returned and opened, including an access failure.
2. [Source ledger](source-ledger.md): primary evidence a writer may use for technical claims.
3. [Rejected outline](rejected-outline.md): the first approach and the changes prompted by research.
4. [Completed brief](completed-brief.md): reader decision, answer plan, cases, exclusions and verification.

The brief contains the complete fictional inputs. Its local consistency check does not replace independent technical and editorial review of whether the assignment is useful.
