Submission Window

Each layer clamps this entropy observation between a submitted-after edge and a submitted-before edge. Only the submitted-before edge is grounded outside Truestamp, by a public-chain commitment transaction. The submitted-after edge is asserted by Truestamp's own block ordering and is not established by this proof.

The submitted-before edge comes from the Stellar commitment transaction. The submitted-after edge is asserted by Truestamp's block ordering, not by Stellar.
