- diagnosis first (migrations/check_old_stubs.php, kept): the six
old-taxonomy pages (#451-454, #456, #458) were completely empty - no
content elements and NO family child pages (the family workbooks were
deliberately never imported), so nothing needed moving
- migrations/retire_old_category_stubs.php (dry-run by default, guards
against children/content) soft-deletes each stub and queues a 301
sys_redirect onto its new-taxonomy equivalent; existing redirects for
a path are kept
- applied and verified live: all six old paths answer with the 301
redirect envelope onto the correct new category page, and the main
navigation now shows exactly the nine new categories in sitemap order
