+# Electra Archon - SEED Architecture Implementation Plan
 
-Next steps in configuring the Electra Archon with SEMD.
+## Overview
+
+This document outlines the SEED Architecture implementation for **Electra Archon*,* the specialized archon for the Allegro house.

+
+## SEED Components for Electra
+
+### 1. State Management (S)
+- Electra-specific state containers
+- Allegro house context integration
+- Real-time state synchronization
+
+### 2. Event Bus (E)
+- Pub/sub configuration for Electra workflows
+- Event filtering and routing
+- Cross-archon event propagation
+
+### 3. Entity Definitions (E)
+- Electra entity schemas
+- Validation rules specific to Allegro domain
+- Relationship mappings
+
+### 4. Data Flow (D)
+- Input/output pipelines
+- Transformation layers
+- Persistence strategies
+
+## Implementation Phases
+
+### Phase 1: Core Setup
+- [ ] Initialize SEED modules
+- [ ] Configure event bus
+- [ ] Set up state store
+
+### Phase 2: Entity Configuration
+- [ ] Define Electra entities
+- [ ] Implement validation
+- [ ] Configure relationships
+
+### Phase 3: Integration
+- [ ] Connect to Allegro house services
+- [ ] Test event flows
+- [ ] Validate state management
+
+## Acceptance Criteria
+
+See Issue #1 for detailed acceptance criteria.
