THE GREEN / RED TEST

Do the files still match the sealed session?

    01 / PRIVACY

    Commitments, not content

    Public receipts prove integrity without publishing private code or agent output.

    02 / ORDER

    Sequence is evidence

    Every event commits the previous event hash. Deletion and reordering break the chain.

    03 / INDEPENDENCE

    Verify without trust

    The EB1 package carries its checksums, root specification, public key and chain proof.
