Only the condition field and the variable name now unwrap a copied {{path}} placeholder (see readUnwrapped in app/islands/AutomationForm.tsx). The loop step's "Array path" input and the reference-name inputs of fetch, search, loop and action steps still store the pasted text verbatim. I read their onInput handlers, which save e.target.value as is. The save-time validators then reject the braces: FOR_EACH_PATH_RE and FETCH_SEARCH_NAME_RE in lib/actions/validation.ts allow no {. The name inputs give no inline error, only the native pattern attribute.
Where to start: route those onInput handlers through readUnwrapped, and reuse the variable step's inline name error (STEP_NAME_RE) for the other name inputs.
