    "Notes": "Strongest: a toggle is traceable in seconds — Router lists every route, owned() is the single ownership seam, afterItemWrite maps error/no-row/success to 500/404/done, and done() explains the 303-vs-fragment split. Comments consistently explain why (Resolve not Run, why not csrf.Protect, parseForm's 1 MiB cap, toggleAll's single-statement race note). Weakest: renderStatus swallows template errors with a bare http.Error and no log or ref, unlike fail(); several `uid, _ := sessions.UserID(r)` rely on an invariant stated only in visitor.go; repeated 'the contract' references assume context the reader lacks; done() is a vague name for 'respond after success'. app.go mixes wiring with parseForm middleware."

    "[correctness] `apps/go-rastrillo/internal/todo/static/app.js:42` — Every action response replaces the entire app, preserving only the new-todo input. With a request pending, double-click another todo and start editing: when the earlier response arrives, the editor disappears and its unsaved text is lost. Preserve the active editor’s value and focus across replacement, or defer replacement until editing finishes."
