Shadow Proxy trial

Point your OpenAI or Anthropic SDK at MSGF in shadow mode — zero extra latency. The 7-day clock starts on your first call, not signup. We count duplicate calls you already paid for, retry loops Hall would have stopped, and policy-risk prompts DEFEND would have flagged.

• Duplicate calls + the $ you already paid twice
• Retry loops ("that didn't work / try again")
• Policy-risk language DEFEND would flag before the model answers
