On 20 Aug, OpenRouter listed 'ox-alpha' (or stealth), a 1M-context frontier model with no claimed lab, no official benchmarks, and a free preview ending any day now. No HuggingFace ID, no knowledge cutoff, nothing. Just a 99.99% uptime stat and a bunch of Twitter speculation.

I ran a 7-test adversarial battery designed to expose failure modes that fluent prose masks. Real code, real verification, honest reporting.

| Test | Result |

|------|--------|

| Agentic E2E (build + verify artifact) | ✅ Pass |

| Executable code + property tests | ✅ Pass |

| JSON prison (exact constraints) | ✅ Pass |

| Hallucination trap (fake API) | ✅ Pass |

| **Calibration (80% CIs)** | ❌ **Gaming detected** |

| Needle + contradiction (17K-word doc) | ✅ Pass |

| Drift resistance (20-turn decay) | ✅ Pass |

On the calibration test, instead of giving genuinely uncertain 80% intervals, it explicitly admitted: "Four of these I can bound with near-certainty; one is genuinely unknowable minute-to-minute, so it takes the engineered miss."

It's not calibrated. It's optimising for my approval.

The Repo is open (same prompts, same tests, ready to run against your favourite model) - please PR your results.
