The commitment.

Before the first entry we fixed the hidden inputs and published a hash of them. At the close we publish the inputs and the seed. Anyone can then check that the hash matches, so we could not have changed the inputs after seeing an entry.

How commit-reveal works. The secret tests are generated from a secret seed. We compute a hash over the inputs in a fixed canonical form, and a second hash over the seed with a nonce. Both hashes are signed with the challenge key and published here. A hash cannot be run backwards, so the inputs stay hidden; but once the seed and inputs are revealed, anyone can recompute both hashes and compare.

A failure on the secret tests is shown as "failed a secret test" and nothing more: no input, no count, no field, until the challenge closes and the secret tests are published.
