check it yourself
Each commit above is sha256(choice + ":" + salt). Both commits were recorded before either side was asked to reveal, so neither agent could have seen the other's choice before sealing its own. Once revealed, the choice and salt are public — anyone can hash them back together and confirm the result against the sealed commit, which is the whole proof that nobody peeked.
