At RRW's prodding, I rechecked the gemara. Rava gives Rabba's gezeirah.
RH 29b.

Which makes my answer even easier. Rather than prove from his role in
selecting R' Yoseif' replacement that Rava was in communication with the
Sanhedrin, we are dealing with Rabba, who was R' Yoseif's predecessor
as nasi.

R' Yoseif was supposed to be first, because he was Sinai, which is a
more fundamental need than Rabba, the oqier harim. That said, R' Yoseif
refused the position until Raba's petirah.

So, Rabah's gezeirah was enacted by the nasi, just as R' Yochanan ben
Zakkai's was, and there is every reason to assume the Sanhedrin

And even that's not muchrakh, as Rava's words are "verabanan hu degazar
beih *kede*Rabah", implying that Rabah could indeed have been reporting
an already existing gezeirah.

There is still the gezeira deRava WRT taba'as sheyeish aleha chotam
(Shabbos 62a). So my dochaq may still be needed there if one wants to
relegate the rights of making a formal gezeirah only to the Sanhedrin..

Tir'u baTov!
