Never mind. :)

You seem to think that I am doubting what you saw. I am not. Actually, I
am confident that you indeed saw it. That is precisely why I offered the
suggestion to log DHCP (and ARP) traffic from within the server and also
the client, to see if for instance the dnsmasq answer was sent out by te
server but not received by the client, or if the answer was never sent.
BTW, this makes me realize that the tests should be performed with
--log-queries and --log-dhcp, so that you can tell if dnsmasq did
produce a reply. Thus, if dnsmasq logs say a reply was sent but tcpdump
or wireshark logs on the server don't show it, then you can tell there
is a network issue on the server, etc.

AFAICT, yes, you should be able to obtain what you are looking for.
Again, I suggest you perform tests, ideally on small independent parts
of your setup.
For instance, you can query DNS records from dnsmasq from within the
server itself using dig; that will allow you to make sure the DNS part
of your config works without being hampered by any DHCP issue. You can
check that domains all get resolved to the right IP, and you can also
test if your server answers to queries to the right IP.
As for the DHCP issue, again, do you have another machine with which you
could query DHCP from a wired machine to the server, i.e., without any
tap and wireless involved? That would help determining if the issue is
in dnsmasq or in your network setup.
