2. AI Agent Ecosystem

// packages/ai-core/src/agents/AgentRegistry.ts
class AgentRegistry {
  private agents: Map<string, Agent>;
  
  register(agent: Agent): void {
    this.agents.set(agent.metadata.id, agent);
  }

  async process(input: AgentInput): Promise<AgentOutput> {
    const pipeline = this.buildPipeline(input);
    return await pipeline.execute();
  }
}

📈 Migration Strategy

Phase 1: Foundation (Weeks 1-4)

• Monorepo setup with Turborepo

• Core service extraction

• Shared package configuration

• CI/CD baseline

Phase 2: AI Modernization (Weeks 5-8)

• Agent registry implementation

• Pipeline refactoring

• Knowledge graph integration

• Compliance hooks

Phase 3: Compliance Certification (Weeks 9-12)

• LHDN full integration

• SOCSO automated submissions

• Zakat state-wide support

• PDPA audit trail

📜 Architectural Decision Records

ADR-001: Monorepo Structure

# 2025-08-01 - Monorepo Adoption

## Status: Approved

## Context:
Existing codebase suffered from:
- Duplicate dependencies
- Inconsistent tooling
- Fragmented builds

## Decision:
Adopt Turborepo with:
- pnpm workspaces
- Shared tooling config
- Unified CI/CD

## Consequences:
✅ Single-version truth
✅ Atomic changes
⚠️ Increased initial setup
