I don't know why it doesn't include in the document. And as my test, you must create a template_node for blackboxing with compile_contents set True.
Also, you can check the file in “Side Effects Software\Houdini 17.5.397\toolkit\include\HOM\HOM_HDADefinition.h”
by the line of 118.
SWIGOUT(%kwargs save;)
virtual void save(
	const std::string &file_name,
	HOM_Node *template_node = NULL,
	HOM_HDAOptions *options = NULL,
	bool compile_contents = false,
	bool black_box = false,
	bool create_backup = true) = 0;

within this context, what is a template node?

I've been able to successfully save a regular HDA with "save" but trying to save a blackbox HDA has gotten me stumped.

Here is what I've been doing:

# trivial subnet
geo = hou.node("/obj").createNode("geo")
subnet = geo.createNode("subnet", "license")

sphere_node = subnet.createNode("sphere")
output_node = subnet.createNode("output")

output_node.setInput(0, sphere_node)


# create HDA node and HDADefinition
hda_node = subnet.createDigitalAsset(name="test", compress_contents=True, version="1.0", save_as_embedded=False, ignore_external_references=True, change_node_type=True, create_backup=False)
hda_def = hda_node.type().definition()"/tmp/test.hda") # works"/tmp/blackbox.hda", black_box=True) # creates regular HDA because no "template_node""/tmp/blackbox.hda", template_node=subnet, black_box=True) # crashes
