  "description": "The envelope of a .recipe file (RECIPE-FILE-v1.md, revision 1.1). The recipe itself is a Canonical Recipe 5.0, defined by its own schema (MyRecipes/Resources/CanonicalRecipe.v5.schema.json, $id https://chef.app/schemas/recipe.v5.json) plus the cross-field rules in docs/CANONICAL-RECIPE.md section 6; it is referenced here, never restated. The optional image is one photograph of the dish (section 2.1); a reader may ignore it and must still open the recipe, so this schema describes what a writer produces, not what a reader must reject. $id values are identifiers, not addresses to fetch. Unknown top-level members are allowed so a reader ignores them; writers add none in v1.",
