Claude Code Helper for Foundation 2.0 Project

Project Vision

Foundation 2.0 is evolving into the next-generation distributed BEAM framework - a comprehensive platform that combines enhanced core services, Partisan-powered distribution, deep BEAM primitives, and intelligent features. The goal is to create the definitive framework for building scalable, fault-tolerant distributed applications on the BEAM.

Foundation 2.0 Architecture

Layer 1: Enhanced Core Services (Distributed + Intelligent)

Foundation.Config 2.0      # Distributed configuration with consensus
Foundation.Events 2.0      # Cluster-wide event streaming with correlation  
Foundation.Telemetry 2.0   # Intelligent metrics with predictive analytics
Foundation.Error 2.0       # Distributed error correlation and learning
Foundation.ServiceRegistry 2.0  # Cross-cluster service mesh
Foundation.ProcessRegistry 2.0  # Distributed process coordination

Layer 2: BEAM Primitives (Partisan-Optimized)

Foundation.BEAM.Distribution    # Partisan topology management (replaces libcluster)
Foundation.BEAM.Channels       # Multi-channel communication patterns
Foundation.BEAM.Processes      # Process ecosystems with distributed coordination
Foundation.BEAM.Messages       # Intelligent message passing optimization
Foundation.BEAM.Schedulers     # Cluster-aware scheduler coordination
Foundation.BEAM.Memory         # Distributed memory management

Layer 3: Distributed Coordination (Partisan-Native)

Foundation.Distributed.Topology    # Dynamic topology management
Foundation.Distributed.Consensus   # Raft over Partisan channels
Foundation.Distributed.Context     # Request tracing across topologies
Foundation.Distributed.State       # CRDTs with Partisan broadcast
Foundation.Distributed.Discovery   # Multi-strategy node discovery
Foundation.Distributed.Routing     # Intelligent message routing
