-**Sovereign data gateway and PII protection platform** built on the [NAAb Language](https://github.com/b-macker/NAAb). Ensures secure passage for sensitive data by validating schemas, detecting PII, and enforcing policies before data reaches untrusted systems.
+SSNs, credit cards, API keys, health records — intercepted and redacted before they leave your system. Passage sits between your application and any external LLM or API and enforces a zero-leakage policy.
 
 ```
-Input:  API request with potential PII
-Output: Validated, redacted, or blocked request
-Result: Zero PII leakage with mathematical certainty
+POST /  {"prompt": "Patient SSN: 123-45-6789, diagnose this"}
+→ {"error": "POLICY_VIOLATION", "blocked": ["ssn_pattern"]}
+
+POST /  {"prompt": "What are symptoms of a cold?"}
+→ {"response": "..."}  ✓ clean request passes through
