First clue. Network name should be "0.0.127.in-addr.arpa". You seem
to be confusing the full name with the containing domain name.
> origin = localhost.1.0.0.127.in-addr.arpa
Second set of clues. Extended domain name, plus "localhost" has the
domain name appended.

Ah, but no domain name appended here. Why not? ;-)
...

Should be zone "0.0.127.in-addr.arpa".
...
> zone "localhost" {
You shouldn't really have a zone "localhost". In your primary zone
file - e.g., in db.acadia.net - you have "localhost" defined. That
will suffice. This zone defines a "localhost.localhost" FQDN. Totally
unnecessary.

This does not give good addresses for either. [However, note that the
question above is answered by observing that you have a "." appended to
the second "localhost", but not the first.] Suggest instead:
@ IN SOA p1.acadia.net. hostmaster.acadia.net. (
> IN NS localhost
Again,
IN NS p1.acadia.net.
IN NS p1.acadia.net.
> 1 IN PTR localhost
1 IN PTR localhost.
_OR_
1 IN PTR localhost.acadia.net.

As mentioned, trash it. ;-)
