VERAX TEKNOLOJI LIMITED SIRKETI Audit evidence is only useful for as long as it can be verified. Cedulon produces COSE spend receipts and epoch checkpoints whose signature algorithms will eventually be deprecated or broken; the recent transition from polymorphic EdDSA to fully-specified Ed25519 algorithm identifiers shows that even identifiers change within a decade. This document proposes a re-attestation profile for Cedulon evidence: a signed statement, produced while the original algorithm is still trustworthy, that binds the original evidence bytes to a successor algorithm and is registered in a SCITT transparency service. Chains of such statements allow a verifier decades later to trust evidence whose original cipher has been retired. Structures are meant to outlive ciphers. This is an extension proposal to the Cedulon core document; its normative language is provisional and the companion implementation does not implement it yet.
