Integrity Test Lab

One altered number.
Broken proof.

Take the first event from BP-001. Change its copied quantity, then verify against the original hash chain.

What this demonstrates

Each event commits to its own content and the previous event hash. A changed measurement breaks this relationship.

A privileged attacker could recalculate an unanchored history. An independent, confirmed blockchain root provides an external reference against that attack.

No testnet anchor is fabricated for this lab.
