After further analysis, I see a pattern and have a hypothesis.

Amelia, how's the program constructing the s6dns_domain_t object that
it passes to skadns_send() for A and AAAA queries? Is it calling
s6dns_domain_encode() or s6dns_domain_encode_list(), i.e., is the
object passed to skadns_send() in packet form instead of string form?
