Oh, sorry! It slipped off my radar.

As we can see from pengine/native.c: native_color(): 516:

if (is_not_set(rsc->flags, pe_rsc_managed)) {
...
        } else if (is_set(rsc->flags, pe_rsc_failed)) {
            reason = "failed";
        } else {
...

So assign_to is NULL for the later call:
native_assign_node(rsc, NULL, assign_to, TRUE);

This means it is allocated to no node. That's why an "unmanaged failed"
resource would not consume the capacity of the node.
