ISL v1.1 and Constitutional Node v1.0 Implementation

This project implements the Intent Specification Language (ISL) v1.1 and Constitutional Node (C-Node) v1.0 specifications for the Constitutional Intelligent Engineering Management System (CIEMS).

Specifications Implemented

• ISL v1.1 (CIEMS-ISL-0011): Intent Specification Language with Multi-Agent Composition, Federated Evidence, and Cross-Organization Governance
• Constitutional Node v1.0 (CIEMS-CNODE-SPEC-001): ISL-Integrated Governance Specification

Architecture

ISL v1.1 Components

• isl/ - ISL payload schema and validation
• isl/payload.py - Core payload data structures
• isl/validation.py - Validation pipeline
• isl/signature.py - Cryptographic signature handling
• isl/composition.py - Multi-agent intent composition
• isl/evidence.py - Federated evidence anchoring
• isl/cross_org.py - Cross-organization governance

Constitutional Node v1.0 Components

• cnode/ - Constitutional Node implementation
• cnode/layers/ - Five-layer architecture
  • intent_layer.py - Intent ingestion boundary
  • isl_interpreter.py - ISL parsing and validation
  • constraint_engine.py - Constraint enforcement
  • evidence_layer.py - Evidence provenance management
  • audit_ledger.py - Append-only cryptographically chained ledger
• cnode/constraints/ - Constraint definitions
• cnode/registry.py - Agent and organization registries

Installation

pip install -r requirements.txt

Usage

from isl.payload import ISLPayload
from cnode.constitutional_node import ConstitutionalNode

# Create an ISL payload
payload = ISLPayload(
    intent_class="directive",
    issuing_agent_id="agent-001",
    target_scope="subsystem",
    intent_body={"action": "deploy", "target_resource": "service-A"}
)

# Process through Constitutional Node
cnode = ConstitutionalNode()
result = cnode.process_intent(payload)

Status

• ISL v1.1 payload schema
• ISL validation pipeline
• Constitutional Node 5-layer architecture
• Multi-agent composition lifecycle
• Federated evidence verification
• Cross-organization governance
• Inter-node protocol
