HOOKBUS SUBSCRIBER #1

CRE
Composable Rule Enforcer

Two-layer governance for AI agents. Every tool call passes through CRE before execution. The AI cannot bypass, disable, or argue with it.

Patent Pending GB2604445.3 Runs on HookBus

Three scenarios. One mechanical gate.

66 SECONDS · HARD BLOCK · KB INJECTION · PIN OVERRIDE

Deterministic speed. Semantic depth.

LAYER 1

Microsoft AGT + Pattern Engine

Under 10ms

Microsoft Agent Governance Toolkit provides semantic threat classification across destructive, exfiltration, and privilege escalation categories. Combined with our proprietary regex pattern engine for your organisation's policies.

LAYER 2

IBM Granite 4 Intent Verification

Under 1s on CPU. No cloud. No GPU.

IBM Granite 4 (Apache 2.0) runs locally. Verifies the AI's action matches what the user actually asked for. Catches substitutions, shortcuts, and creative reinterpretations.

What CRE does that system prompts cannot.

Mechanical enforcement

Operates outside the AI's context window as a mandatory checkpoint. The AI cannot skip, modify, or argue with it.

Intent alignment

L2 verifies the agent's tool call matches the user's explicit instruction. Nobody else checks this.

PIN override

Human approval chain for sensitive operations. The user types override 0000, CRE retries, the audit trail records it.

Self-learning rules

L2 decisions automatically promote to L1 patterns with human approval. Faster and more accurate over time.

Anti-evasion

Detects encoded commands, lateral movement, and scripts designed to bypass enforcement.

SOC2-ready, ISO 27001-ready, ISO 42001-ready

Full audit trail, every decision logged. Works with HookBus Auditor for compliance evidence.
