Weekly slugs: keep a collision and redirect checklist

For recurring content publishing, generate a readable slug from each new title, then check it against existing routes before saving. Keep a record of old slugs and redirects when titles change; changing a URL silently can break bookmarks and search links. Test punctuation, repeated spaces, and non-ASCII letters with the same normalization policy each week. A repeatable slug rule is useful only if uniqueness and continuity are checked too.
