We should split PrivCount secrets and aggregate them using privcount_shamir. We'll need to merge privcount_shamir into tor, and use it on the Data Collector and Tally Reporter.

This could take a few days, depending on how much we improve privcount_shamir before merging it.

Let's review these tickets at the next meeting using our 041-proposed process.

They're on the roadmap, so the review should focus on ticket size and team capacity (and sponsor expectations).

These PrivCount tickets are on the 041 roadmap, we accepted their points estimates in 041 without discussion.
