Phi Screen is a runtime control that blocks dangerous or unintended data paths before they execute. It enforces precise boundaries inside your system, catching violations at the source. No stale inputs slip through. No unsafe calls survive. When enabled, execution only passes through verified routes, reducing critical failure points without slowing performance.
It works at the framework level. Phi Screen reads every inbound and outbound transfer, applying checks that you define. Those checks can enforce type safety, required tokens, or trust levels. If a call fails validation, it never touches the logic layer. This stops injection attacks, corrupted payloads, and unauthorized requests cold.
Implementation is straightforward. Inject Phi Screen into middleware, set your validation schema, and flag enforcement mode. Logs capture rejected attempts with full tracebacks, letting you tune rules without guesswork. Deployment is frictionless—hooks integrate with your CI/CD pipeline, so you test and ship without manual intervention.
