While a null-client configuration may not be an appropriate default
for an out of the box machine, it is definitely easily supported:

Very helpful, more so than
http://www.postfix.org/STANDARD_CONFIGURATION_README.html#null_client
(subsequently discovered).
Since postmaster bounces are handled on the mail gateway machine, DNS is
sane and used by the gateway, the minimum necessary configuration for
main.cf appears to be:
master_service_disable = inet
mydestination =
local_transport = error:local delivery is disabled
alias_database =
alias_maps =
local_recipient_maps =
relayhost = [mailhost.sandbox.com]
On the client machine in question (more come later), postconf -d indicates
no need to set myhostname or mydomain.
With per-host MX records, this handles root, local users, remote users and
non-existent users for internal and external deliveries.
Thank you for your help.
