  • Implement pipeline architecture interfaces
  • Develop content query and operation models
  • Define caching interfaces

• Base Implementation

  • Create ContentMediatorImpl class
  • Implement standard capability profiles
  • Add content resolution logic
  • Implement stream registration and management
  • Create memory-based cache strategy
  • Add health monitoring system

2. Frontmatter Enhancement

• Update gray-matter implementation

  • Use matter.test() to detect frontmatter presence
  • Improve error handling for malformed frontmatter
  • Support additional frontmatter formats (YAML, TOML, JSON)

• Enhance frontmatter typing

  • Create strongly-typed interfaces
  • Add schema validation
  • Implement runtime type checking

3. Registry Implementation

• Implement mediator foundation

  • Create stream registration system
  • Add URI resolution logic
  • Implement capability querying
  • Add proper resource management

• Add stream coordination

  • Implement priority-based stream selection
  • Create pattern matching for path resolution
  • Add fallback mechanisms for content resolution
  • Implement content composition from multiple sources

4. Content Pipeline

• Implement pipeline stages

  • Create resolvers for content URIs
  • Add fetchers for content retrieval
  • Implement transformers for content processing
  • Add enrichers for additional content metadata

• Pipeline orchestration

  • Add pipeline context management
  • Implement stage execution logic
  • Add performance monitoring
  • Create error handling and recovery

5. React Integration

• Create provider components

  • Implement ContentProvider for React context
  • Add configuration props
  • Create error boundaries

• Develop React hooks

  • Create useContent for content fetching
  • Add useContentList for content listings
  • Implement useContentChanges for reactive updates
  • Add useContentCapabilities for adaptation
  • Create useContentOperation for content mutations

Implementation Strategy

1. Start with core interfaces from ADR-005
2. Enhance frontmatter handling for better metadata
3. Implement the content mediator
4. Create the pipeline architecture
5. Develop React integration components

Progress on TypeScript Error Resolution

Type System Reorganization

• Created type definition files in src/lib/types/ organized by domain:
  • content/: Content-related types
  • rx/: RxJS-related types
  • mdx/: MDX-related types
• Moved types from flat files to structured folders
• Consolidated testing utilities in src/lib/testing/
• Added missing utility functions for testing observables

Content Mediator Implementation

• Implemented core components of the ContentMediator:
  • CapabilityProfileManager: Manages capability profiles and provides methods for capability matching
  • StreamRegistry: Manages stream registration, selection, and capability determination
  • StreamHealthMonitor: Monitors stream health and reliability with automatic recovery
  • ContentMediator: Main implementation that coordinates between streams
• Established clean, domain-based directory structure

Key Design Decisions

• Capability Profiles: Implemented flexible capability model with different levels (NONE, BASIC, PARTIAL, FULL)
• Stream Selection Strategy: Added multiple selection strategies (URI-based, capability-based, specific)
• Health Monitoring: Created robust health monitoring system with metrics
• Resource Management: Ensured proper resource cleanup through subscription management

Testing Focus

• Use marble testing for observable streams
• Create mock implementations for testing
• Ensure proper resource cleanup
• Test error handling and recovery scenarios

Completion Criteria

• ADR-005 fully implemented with all interfaces
• Content from multiple sources properly coordinated
• React components adapt to available capabilities
• All operations properly handle errors with context
• Resources are properly cleaned up
