I think that not unreasonably, 'metalinguistic' is being used to
cover what Grice called 'conventional implicature'.

If {po'o} is 'metalinguistic' then it ought to mean something like
'merely'. As pc & I have always maintained, logical 'only' ought
not to be done by {po'o}: ("only X are P" = "every P is X").

Likewise, I feel strongly that {da'i} ought not alter truth conditions;
it should indicate that the speaker is not claiming the proposition
within its scope to be true.

Not every unmarked sentence is a claim. Without overt indicators,
the illocutionary force has to be glorked from context, though of
course without strong contextual evidence to the contrary, we do
assume that an unmarked sentence is a claim.

"broda sei cumki" could then reasonably interpreted as something
like "Broda? (perhaps)", where no claim is being made, and the
speaker is making an incidental/parentheticl indication that they
think it possible that "broda" is true.

Adverbs are of course a heterogeneous class, both syntactically
and semantically. But taking your 'average' adverb, logically
it would normally correspond to a predicate, predicated of
a proposition (or state-of-affairs). But if you want to keep
adverby sort of syntax, then use a BAI, either the BAI for 
manner, or else fi'o. Placing the modal before the selbri allows
for the omission of the sumti.
