There is debate, but quickly; somebody might tip off Zon-Kuthon and then it all becomes harder.

Most gods, not all, combine their powers; the rest agree at least not to interfere.

A vault is forged, with a key that Iomedae alone can turn.

Sarenrae temporarily focuses nearly all Her will on the vault where Rovagug is imprisoned, she could not protect that vault from a full assault by Zon-Kuthon from every direction, but with Zon-Kuthon otherwise distracted she will be able to fend off any lesser attempts at that, if it does not come as a surprise.  There also does Otolmens stand guard.

And most of the other gods of Golarion assault Zon-Kuthon, everywhere that is not that vault; Zon-Kuthon must put the greater parts of Himself within it, or else be vastly diminished.

That Zon-Kuthon will scatter smaller-sized fragments of His will and power beyond the vault, yet linked to His greater whole, is inevitable; it is not easy to really, really kill a god, if they have not made themselves vulnerable by collecting themselves too much into one place.
