Is “pwd >/dev/full” an “unrecoverable error condition” as regards
the pwd utility?

No. the pwd utility has had its stdout redirected by its
parent, "the shell". Since the faulty redirection was done by parent,
is the error in the child or the parent?

along those lines:
/tmp pwd >& /dev/zero
-bash: /dev/zero: Permission denied
/tmp> echo $?
1
/tmp> cd ~>& /dev/zero #note the command isn't executed
-bash: /dev/zero: Permission denied
/tmp>
