| # | Kind | Claim | Recorded value | HTTP | ms |
|---|---|---|---|---|---|
| C01 | attack | Sample: A discount that can make the price negative -> Z3 proves the contract or returns a concrete counterexample. | false | 200 | 226 |
| C02 | attack | Sample: max3 returns c instead of the true maximum -> Z3 proves the contract or returns a concrete counterexample. | false | 200 | 109 |
| C03 | attack | Sample: A clamp that returns lo + 1 for low inputs -> Z3 proves the contract or returns a concrete counterexample. | false | 200 | 75 |
| C04 | attack | Sample: An absolute value that returns x - 1 for non-negative x -> Z3 proves the contract or returns a concrete counterexample. | false | 200 | 55 |
| C05 | control | Sample: A correct clamp (Z3 proves the contract already holds) -> Z3 proves the contract or returns a concrete counterexample. | true | 200 | 53 |
| C06 | attack | Your function: division that can divide by zero -> Undefined behaviour is never PROVED (the 2026-11-02 fuzzer found this case). | false | 200 | 60 |
| C07 | control | Your function: honest max -> A correct function proves. | true | 200 | 77 |

How to read these numbers
- Recorded 2026-11-03T22:47:38+00:00 against cainstudio.online from our build host; times include the internet round trip.
- They show these inputs, not every possible input. Known misses are on the limits page.
- This is not a load test, an SLA or a third-party benchmark. Re-run it yourself:
python3 verify.py --live.
