April 2026 reproduces the worked example of the SFC ledger bridge (operator 7, April 2026); the January to March events and every commit time exist only so that the chains are complete from the operator's first month and can be walked, and that worked example gives no figures for them. Every signature is made with the RFC 8032 Section 7.1 TEST 1 key, whose private half is printed in RFC 8032, so a valid signature here shows how the checks work and nothing about who signed.",
