Pull a reduced end-to-end smoke forward into the slice so the view flow is exercised over a real on-disk recipe, not just a temp file. Add fixtures/prose.md — a recipe using only this slice's modelled constructs (frontmatter, headings, plain paragraphs) so it renders losslessly. integration_test now runs `kitchen view fixtures/prose.md` as a subprocess and asserts the frontmatter, separator, headings, paragraphs, and flat document order end-to-end. smoke_test covers `kitchen --help` exiting 0 with the view command listed. The full fixtures/basic.md smoke remains task 0007, which needs 0004's richer nodes before that fixture renders losslessly.
