+# Agent OS Kernel
+
+AIOS v5.1 direction:
+
+- Agent process model
+- Lifecycle manager
+- Resource manager
+- Isolation
+- Agent IPC
+- Recovery
+
+Agent lifecycle:
+
+CREATED -> INITIALIZING -> READY -> RUNNING -> WAITING -> SUSPENDED -> TERMINATED
+
+All autonomous changes require policy checks and audit trails.

+# AIOS v5 Architecture Foundation
+
+## Vision
+
+AIOS v5 evolves into an agent operating system with:
+
+- Runtime API
+- Orchestrator
+- Execution Kernel
+- Event Bus
+- Memory Graph
+- Skill Engine
+- Multi-Agent Scheduler
+- Distributed Workers
+- Security Governance
+- Production Runtime
+
+## Execution Flow
+
+User -> Runtime API -> Orchestrator -> Scheduler -> Agent -> Security -> ExecutionKernel -> Tools -> EventBus -> Memory/Skills/Audit
+
+## Migration Roadmap
+
+1. Core Foundation
+2. ExecutionKernel
+3. EventBus
+4. Orchestrator v5
+5. Memory Graph + Recovery
+6. Skill Engine
+7. Multi-Agent Scheduler
+8. Distributed Runtime
+9. Security Layer
+10. Production Hardening
+
+## Agent OS Direction
+
+Future versions introduce:
+
+- Agent lifecycle management
+- Resource quotas
+- Plugin ecosystem
+- Evolution loops
+- Knowledge consolidation
