Black-Fortress Protocol

Pre-Installation Agentic Sandboxing & Interrogation.

This fortress does not monitor intentions. It enforces physical laws.

A feature that cannot survive this protocol does not deserve execution.

When to Use

• Before installing any third-party agent/skill/feature into production
• Before executing untrusted code from external sources
• When validating AI-generated code for deployment
• When a feature's behavior must be verified beyond code review

Requirements

No API keys, no cloud accounts, no external services. The entire protocol runs locally.

The Semantic Paradox (Security Feature)

Black-Fortress Layer 1 obfuscation is designed to preserve AST (Abstract Syntax Tree) logic while destroying all surface-level semantics. This means:

• ✅ Control flow (if/else, loops, exceptions) is preserved exactly
• ✅ Function signatures (arity, return types) are preserved
• ✅ Import structure is preserved
• ❌ Variable names, function names, class names → randomized hashes
• ❌ Comments, docstrings → stripped entirely
• ❌ String literals >50 chars → truncated

Any code that relies on hardcoded string-reflection (e.g., getattr(obj, "user_input"), eval(), exec() with dynamic strings, __name__ comparisons) will intentionally break under obfuscation.
