Exactly — this is the circular nightmare in action.

1. Dev gets 401 / rate-limit / weird error 2. Pastes full API key + request into GPT-4o / Claude for "why isn't this working?" 3. That key (or close pattern) enters the training pipeline 4. Model learns valid key structures / patterns from real usage 5. Later prompts extract similar internals (like our EPHEMERAL_KEY leaks)

I saw this repeatedly: different vectors → same leaked concept every time.

Your bill-spike point is brutal. We ran these tests for ~$0.04. An attacker could probe 10,000 variants for $4 and map your API surface before you notice anything.

Key rotation helps post-breach, but proactive multi-vector probing (what we're building continuous tests for) catches the pattern before exploitation.

Spot-on observation. Thanks.
