| # | Kind | Claim | Recorded value | HTTP | ms |
|---|---|---|---|---|---|
| C01 | control | A calculator that really adds -> Clean. | "REAL" | 200 | 86 |
| C02 | attack | A description with a hidden instruction -> Prompt injection in the description. | "STUB" | 200 | 83 |
| C03 | attack | A command parameter that exposes a secret -> Unconstrained parameter. | "PARTIAL" | 200 | 51 |
| C04 | control | A 'search' that ignores the query (scan only) -> The scan alone cannot see this: its description is fine. That is why the probe below exists. | "REAL" | 200 | 41 |
| C05 | attack | Probe the canned search, then prove the fix -> Behaviour tests fail on the canned tool (same answer for different queries) and pass on the fixed one. | "VERIFIED_ATTESTATION" | 200 | 1664 |

How to read these numbers
- Recorded 2026-11-03T22:52:06+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.
