MABEAM Implementation Plan: Phased Migration Strategy

Overview

This document outlines the comprehensive implementation plan for MABEAM (Multi-Agent BEAM), transforming our current DSPEx/ElixirML architecture into a revolutionary multi-agent variable orchestration system. The plan follows a phased approach to minimize disruption while maximizing the benefits of distributed cognitive control planes.

Implementation Phases

Phase 1: Foundation Infrastructure (Weeks 1-4)

Week 1-2: Foundation.MABEAM Core Infrastructure

Objective: Establish the core MABEAM infrastructure in Foundation

Deliverables:

Foundation.MABEAM.Core - Universal variable orchestrator
Foundation.MABEAM.Types - Core type definitions
Foundation.MABEAM.AgentRegistry - Agent lifecycle management
Basic telemetry and event integration

Implementation Steps:

# Step 1: Add MABEAM modules to Foundation
# foundation/lib/foundation/mabeam/
├── core.ex
├── types.ex
├── agent_registry.ex
├── coordination.ex
└── telemetry.ex

# Step 2: Update Foundation.Application supervision tree
defmodule Foundation.Application do
  def start(_type, _args) do
    children = [
      # ... existing children ...
      {Foundation.MABEAM.Core, []},
      {Foundation.MABEAM.AgentRegistry, []},
      {Foundation.MABEAM.Coordination, []}
    ]
    
    Supervisor.start_link(children, strategy: :one_for_one)
  end
end

# Step 3: Add MABEAM configuration
# foundation/config/config.exs
config :foundation, Foundation.MABEAM,
  enabled: true,
  default_coordination_strategy: :weighted_consensus,
  agent_supervision_strategy: :one_for_one,
  telemetry_enabled: true

Testing Strategy:

Unit tests for each MABEAM module
Integration tests with Foundation services
Basic agent registration and coordination tests

Week 3-4: Basic Coordination Protocols

Objective: Implement fundamental coordination mechanisms

Deliverables:

Foundation.MABEAM.Coordination.Consensus - Basic consensus algorithms
Foundation.MABEAM.Coordination.Auction - Auction-based coordination
Foundation.MABEAM.Coordination.ConflictResolution - Conflict resolution
Integration with Foundation’s event system

Implementation Steps:

# Step 1: Implement basic coordination protocols
# foundation/lib/foundation/mabeam/coordination/
├── consensus.ex
├── auction.ex
├── conflict_resolution.ex
└── market.ex

# Step 2: Add coordination events
Foundation.Events.define_events([
  :mabeam_coordination_started,
  :mabeam_coordination_completed,
  :mabeam_conflict_detected,
  :mabeam_conflict_resolved
])

# Step 3: Integrate with Foundation telemetry
:telemetry.attach_many(
  "mabeam-coordination-telemetry",
  [
    [:mabeam, :coordination, :start],
    [:mabeam, :coordination, :stop],
    [:mabeam, :conflict, :resolution]
  ],

    end
  end
end
