Crate exo_gatekeeper 

EXOCHAIN Gatekeeper — the Judicial Branch.

This crate implements the Constitutional Governance Runtime (CGR):

• Kernel — immutable adjudicator enforcing constitutional invariants
• Invariants — the eight constitutional invariants
• Combinator — deterministic algebra for composing governance operations
• Holon — autonomous agent runtime with kernel-adjudicated steps
• MCP — Model Context Protocol enforcement for AI systems
• TEE — Trusted Execution Environment attestation
• Governance Monitor — T-14 defense: signed attestation, circuit breaker, human approval gate
