It seems like there's three options for the layer type however:

noir_json_parser/src/enums.nr

Lines 25 to 29 in 69b1435

	pub(crate) mod Layer {
	pub(crate) global OBJECT_LAYER: u32 = 0;
	pub(crate) global ARRAY_LAYER: u32 = 1;
	pub(crate) global SINGLE_VALUE_LAYER: u32 = 2;
	}

Looks like this needs more investigation.

noir_json_parser/src/transcript_entry.nr

Line 42 in 10146b0

assert(r.push_layer_type_of_root * r.push_layer_type_of_root == r.push_layer_type_of_root);

single_value_layer isn't used in the implementation, as standalone values are not supported by this library. Previously, we also checked that this value was a boolean.

Ok, can you remove this from the enum in that case?
