Walnuts
This page is an autonomy-created stub. The routing audit identified 4 source pages in the corpus declaring ingredients: [walnuts] in their frontmatter without a dedicated page existing. Per OPERATING.md Part 3, the autonomy loop created this stub so those sources route to a defined target. The synthesis pass per CLAUDE.md Part 9 fills in the contamination profile as sources accumulate.
