Evidence health

Evidence rots quietly. A figure that stopped being served, a hash that no longer matches, a timestamp batch that never completed: none of these announce themselves, and all of them matter years later. These checks run continuously against randomly selected historical publications so that a fault surfaces long before anyone needs the evidence.

Coverage below 100% is normal for recent publications: timestamping and custody run in batches, so a publication released in the last few minutes has not been through either yet. Coverage that stops rising is the fault worth looking at.
