Documentation Structure and Progress

This document outlines the approved documentation structure for the ReX project, organizing content into focused, high-level categories, and tracking implementation progress.

Domain-Based Implementation Approach

This project adopts a domain-based implementation approach that interweaves conceptual documentation with type implementation and reference documentation. For each domain:

1. Document the concept: Create the conceptual documentation explaining the principles
2. Implement the types: Define the related TypeScript interfaces and types
3. Create reference documentation: Document the API and implementation details
4. Add examples and tests: Provide code examples and tests to validate the implementation

This approach maintains causal consistency between concepts and implementation, improves validation, and creates more coherent modules.

Integration with Trimodal Methodology

The domain-based approach integrates with the Trimodal Methodology framework in the following ways:

Bottom-Up Implementation

• Each domain starts with specific implementation details (types, interfaces)
• Core functionality is tested first within each domain
• Focus remains on concrete details before moving to abstractions

Top-Down API Design

• Domain interfaces are designed early to establish clear contracts
• Cross-domain boundaries are explicitly defined
• Consistent design principles are maintained across domains

Holistic System Integration

• Domains are connected through explicit relationship documentation
• Cross-cutting concerns (security, telemetry) span multiple domains
• Integration points are clearly identified and documented

Documentation Style Guidelines

• Consistency: Use consistent terminology throughout
• Progressive disclosure: Start with basics, then reveal complexity
• Code examples: Include practical, tested code examples
• Visual aids: Use Mermaid diagrams directly inline for complex concepts
• Cross-referencing: Link related concepts
• Non-existent links: Format as ~~Document Name~~ [TODO] for unimplemented documentation
• Audience awareness: Address both beginners and advanced users
• Scannability: Use clear headings, lists, and tables
• Completeness: Cover both happy path and error scenarios
