Module certificate 

The private wire adapter for Tempo’s Simplex finalization certificates.

The pinned format is UInt(epoch) || UInt(view) || UInt(parent) || digest || vote || seed, with two compressed 48-byte MinSig signatures. The vote signs the whole proposal, while the seed signs only its epoch and view. Integers use Commonware’s unsigned varints, not fixed-width Ethereum quantities. Keep this adapter aligned with the pinned upstream definitions:

• Commonware 2026.9.0 Proposal and Finalization.
• Commonware 2026.9.0 threshold VRF signature pair and namespaces.
• Tempo’s pinned TEMPO namespace.
