External reference URLs (methodology guides)

Curated list of https targets cited in Methodology guides (blueprint) and mirrored in docs/methodologies-*.html and in generated Process & flows pages (methodologies-*-process.html). When you change a URL in Markdown, update the matching handbook page’s “Authoritative sources” / “Authoritative sources & further reading” section (and re-run build_methodology_chapters.py for generated HTML).

Each row includes an executive summary: what the link is and why this blueprint points to it, so readers can decide whether to open it.

Quick verification (maintainers)

From a shell, expect HTTP 200 (some sites return 301 then 200 when following redirects):

urls=(
  https://agilemanifesto.org/
  https://www.scrum.org/resources/what-is-scrum
  https://kanban.university/kanban-guide
  https://owasp.org/www-project-top-10-for-large-language-model-applications/
)
for u in "${urls[@]}"; do
  printf '%s ' "$(curl -sS -o /dev/null -w '%{http_code}' -L --max-time 15 "$u")"
  echo "$u"
done

Expand the array with any new links before merging doc changes.
