Merkle inclusion proof

leaf (index 0)0x50a8…99ec
merkle root0x50a8…99ec

Recombining the leaf with each sibling hash in order should reproduce this root independently — this is the raw proof, not just a pass/fail check.

Trust not established in this browser context

Nothing above checks the signature against an independent authority, or links this record to a trusted checkpoint. That requires offline verification via biochain-cli with a separately, independently provisioned trust-anchor profile — a real, separate capability this browser session cannot perform on its own.
