Epochs
One distribution per day, each one checkable
The distributor is not wired to a deployment in this environment. Numbers appear once the contract addresses are set.
Why every epoch is checkable
Rankings are computed off chain, because measuring social usage needs data no contract can read and ranking thousands of entries would not fit in a block. What lands on chain is a single commitment per epoch.
That commitment is only worth something if it can be checked, so every epoch publishes the measurements behind it. Rebuild the ranking from that data and you have to arrive at the same root the contract stores. If you do not, the mismatch is public and provable.
An epoch cannot be published twice, and one whose measurement did not complete is not published at all. A day with incomplete data costs a day of accrual; a day distributed on bad data could not be undone.
