+# AgentMesh Integration for Semantic Kernel
+
+AgentMesh trust and governance layer integration for Semantic Kernel - enabling cryptographic identity verification and policy-based governance for AI agents.
+
+## Overview
+
+This integration provides:
+
+- **GovernedAgent**: Wrap agents with governance policies
+- **GovernanceKernel**: Policy enforcement for kernel operations
+- **Cryptographic Identity**: CMVK/Ed25519 based agent authentication
+- **Trust Verification**: Multi-agent handshake protocols
+
+## Usage
+
+### Creating a Governed Agent
+
+```python
+from semantic_kernel.agents.agentmesh import (
+    CMVKIdentity,
+    GovernedAgent,
+    GovernancePolicy,
+)
+
+# Generate cryptographic identity
+identity = CMVKIdentity.generate(
+    agent_name="assistant-agent",
+    capabilities=["chat", "code_generation"]
+)
+
+# Define governance policy
+policy = GovernancePolicy(
+    max_requests_per_minute=30,
+    allowed_functions=["chat", "generate_code"],
+    audit_all_invocations=True,
+    require_trust_verification=True,
+)
+
+# Create governed agent
+governed_agent = GovernedAgent(
+    agent=base_agent,
+    identity=identity,
+    policy=policy,
+)
+```
+
+### Governance Kernel
+
+```python
+from semantic_kernel.agents.agentmesh import GovernanceKernel
+
+# Wrap kernel with governance
+governed_kernel = GovernanceKernel(
+    kernel=kernel,
+    identity=identity,
+    policy=policy,
+)
+
+# Invoke with governance checks
+result = await governed_kernel.invoke_function(
+    "chat",
+    invoker_card=requester_card,
+    message="Hello",
+)
+```
+
+### Trust Verification
+
+```python
+from semantic_kernel.agents.agentmesh import TrustHandshake, TrustedAgentCard
+
+# Create agent card
+card = TrustedAgentCard(
+    name="my-agent",
+    description="A helpful agent",
+    capabilities=["chat"],
+)
+card.sign(identity)
+
+# Verify peer before interaction
+handshake = TrustHandshake(my_identity=identity)
+result = handshake.verify_peer(peer_card)
+
+if result.trusted:
+    # Safe to interact
+    pass
+```
+
+## Features
+
+### GovernancePolicy
+
+| Setting | Description | Default |
+|---------|-------------|---------|
+| `max_requests_per_minute` | Rate limit per minute | 60 |
+| `max_requests_per_hour` | Rate limit per hour | 1000 |
+| `allowed_functions` | Whitelist of functions | None (all) |
+| `denied_functions` | Blacklist of functions | None |
+| `max_concurrent_tasks` | Concurrent task limit | 10 |
+| `audit_all_invocations` | Audit every call | False |
+| `require_trust_verification` | Require identity | True |
+| `min_trust_score` | Minimum trust score | 0.7 |
+
+### Policy Violations
+
+The governance layer tracks violations:
+
+```python
+violations = governed_kernel.get_violations()
+for v in violations:
+    print(f"{v.violation_type}: {v.details}")
+```
+
+### Audit Logging
+
+```python
+# Get audit log
+audit_log = governed_kernel.get_audit_log()
+
+# Get summary
+summary = governed_kernel.get_governance_summary()
+print(f"Total violations: {summary['total_violations']}")
+```
+
+## Security Model
+
+Uses Ed25519 cryptography for:
+- Agent identity generation
+- Request signing
+- Peer verification
