Batch summary
One batch per chain. The study wants about 10 conforming samples on each chain, a research target rather than a quota.
Samples in custody
Live mints under observation. Time left runs to the public mint end, or to T₀ + 24h once a window is open, counted from the data time.
Results register
Tested samples: their first 24 hours after T₀, and whether each conforms to the qualification gate. Newest T₀ first within each batch.
Study health
Why tested samples fail the gate, and how often the collector could fill each field, per chain.
