# sitemap-core.xml — human-authored L0-L4 pages
#
# Highest crawl-priority sitemap: ~1,047 manually-authored pages including
# all top-level lanes (program, agenda, corpus root + construction-spine +
# foundational-hinges, verify, publications, impact, engage, discover,
# media, results overview pages, etc.) but excluding the 7,800+ auto-
# generated programmatic pages routed via the other five child sitemaps.
#
# Inclusion rule: classifier `_bucket == "core"` from
# `_includes/sitemap-bucket.liquid`.
