	if (!r) return null
	if (r.productCode) {
		r.productCode = parseInt(r.productCode)
		r.product = (util.products.categories[r.productCode] || {}).type || null
		r.mode = modes[r.productCode]
		r.public = true
	} else if (r.class) {
		r.product = (util.products.bitmasks[r.class] || {}).type || null
		r.mode = modesByClass[r.class]
		r.public = true
	}
	if (r.name) {
		r.id = slugg(r.name.trim())

		const l = parseLineName(r.name)
		if (l && l.type) {
