Reading Roadmap

For Project Managers/Architects:

  1. Start with EXECUTIVE_SUMMARY.txt (10 min)
  2. Review IMPLEMENTATION_GUIDE.md section 5 (5 min) for timeline
  3. Keep QUICK_REFERENCE.md handy for lookups (ongoing)

For Developers:

  1. Start with EXECUTIVE_SUMMARY.txt (10 min)
  2. Read QUICK_REFERENCE.md (10 min) for baseline knowledge
  3. Deep dive into CODEBASE_ANALYSIS.md (45 min) sections 2-5
  4. Use IMPLEMENTATION_GUIDE.md as checklist during development

For Code Reviewers:

  1. Skim QUICK_REFERENCE.md (5 min) for conventions
  2. Reference CODEBASE_ANALYSIS.md section 10 (5 min) for principles
  3. Use IMPLEMENTATION_GUIDE.md ADR section for decision context

For Architects Extending the System:

  1. Read CODEBASE_ANALYSIS.md sections 4, 5, 9, 10 (30 min)
  2. Study IMPLEMENTATION_GUIDE.md sections 2, 3, 7 (20 min)
  3. Use as reference for new component design

Key Takeaways

Architecture

  • Interface-first design with 75+ interfaces
  • Generic type parameters: <T, TInput, TOutput>
  • Separation: Abstractions → Base classes → Implementations
  • Builder pattern for configuration

Directories to Know

  • /src/Interfaces/ - All contracts
  • /src/Models/Options/ - All configurations
  • /src/Models/Results/ - All result objects
  • /src/Exceptions/ - All exceptions
  • /src/Enums/ - All enumerations

New Components Go Here

  • /src/DataVersioning/
  • /src/ExperimentTracking/
  • /src/TrainingMonitoring/
  • /src/CheckpointManagement/
  • /src/HyperparameterOptimization/
  • /src/ModelRegistry/

Files to Study First

  1. /src/Interfaces/IModel.cs - Core concept
  2. /src/Interfaces/IOptimizer.cs - Training concept
  3. /src/Optimizers/OptimizerBase.cs - Hook points
  4. /src/Models/ModelMetadata.cs - Metadata pattern
  5. /src/AiModelBuilder.cs - Builder pattern

Implementation Timeline

Phase 1 (Foundation): 4 weeks

  • Data Versioning
  • Experiment Tracking
  • Training Monitoring

Phase 2 (Advanced): 4 weeks

  • Checkpoint Management
  • Hyperparameter Optimization
  • Model Registry

Total: ~8 weeks, ~130-200 files

Success Criteria

Components are ready when:

  • All interfaces defined and documented
  • 80%+ unit test coverage
  • Integration tests pass
  • Example code works
  • Configuration validates properly
  • Serialization works (round-trip)
  • No compiler warnings
  • Code review approved
  • Documentation complete

Questions & Answers

Q: Where should I put my new class? A: Check QUICK_REFERENCE.md "Naming Conventions at a Glance" and IMPLEMENTATION_GUIDE.md "File Naming Convention Summary"

Q: What interfaces should I implement? A: See CODEBASE_ANALYSIS.md section 6 recommendations for your component, or IMPLEMENTATION_GUIDE.md implementation checklist

Q: How do I follow the naming convention? A: See QUICK_REFERENCE.md or IMPLEMENTATION_GUIDE.md file naming tables

Q: What's the integration point? A: See CODEBASE_ANALYSIS.md section 6 "Integration Points" for each component

Q: How many files should I create? A: See IMPLEMENTATION_GUIDE.md component overview - ranges from 15-35 files per component

Q: What's the implementation order? A: Phase 1: DataVersioning → ExperimentTracking → TrainingMonitoring Phase 2: CheckpointManagement → HyperparameterOptimization → ModelRegistry (See CODEBASE_ANALYSIS.md section 8 for rationale)
