Proof Before Promise means execution comes before communication. A claim should point to something that exists, runs, or can be independently checked. For SBA, this means we do not ask people to believe a narrative first. We build the system, document the logic, expose the verification path, and then communicate what can be checked.
Proof can be a deployed contract, verified source code, transaction history, system documentation, analyzer output, or any other public reference that allows someone to verify the claim instead of trusting it blindly.
