Guardian Intake Gateway

Govern external content before it becomes model context.

SPECIFICATIONCognitive firewall / zero-trust intake

The Problem

AI systems accept raw external content—documents, emails, tool descriptions, API responses—directly into their reasoning context without verification. This creates a cognitive attack surface where hostile meaning can be injected through prompt injection, false authority, tool poisoning, context poisoning, hidden instructions, and memory contamination.

The Approach

Guardian establishes a model-facing trust boundary. Raw intake flows through a six-zone pipeline: Session Binding → Activation Binding → Quarantine → Traditional Security Analysis → AI-Native Content Analysis → Sanitization → Provenance Capture → Lifecycle Policy → ReceptorEvent → Guard Decision → Controlled Model Representation → Continuity Record → Audit/Retention/Purge. The ReceptorEvent is governed evidence, not truth, permission, or memory. Guardian modules include File, Mail, MCP, Extension, Enterprise, Local Receptors, Receptor API, Lifecycle Console, and Audit Console.

What Exists Today

  • ✓Guardian Intake Gateway architecture specification
  • ✓Local MVP direction defined
  • ✓Receptor module taxonomy specified
  • ✓Audit service prototype demonstrates source, hash, manifest, risk, and policy checks with receipt generation

//What It Does Not Prove

What this project does not prove.

  • ✗Not independently certified
  • ✗No production deployment demonstrated
  • ✗Threat coverage incomplete
  • ✗Benchmark validation incomplete
