The viewer box head built the param signature in round parens — SMA(length) — which reads as a function call. Switch the brackets to square — SMA[length] — so the head reads as parametrisation, not invocation. cellLabel render-only change in graph-viewer.js; the JSON model surface and both goldens are untouched.
