Break the Pattern

Run a documented edge-case test against the safe demo contract: call probe(value) with a boundary value so the contract classifies it as an edge case. Found a real failure instead? Report it through Signal Report.

Steps

01Pick a value to probe. Boundary classes: 0, the maximum uint256, or any power of two.
02Call probe(missionId, version, value) on the official Signal contract.
03The contract emits BoundaryProbed with a classification kind (0 = none, 1 = zero, 2 = max, 3 = power of two).
04The verifier accepts kinds 1, 2 and 3. Non-boundary values are recorded but do not pass.

Connect a wallet and sign a one-time message to prove you control it. Signing is free and sends no transaction.

Known limitations & risks

▲Only test the official demo contract. Never attack third-party systems.
▲Score depends on a verified outcome, not on the number of attempts.
