[WIP] Configuration Management System with YAML-based Reference Data

[Copilot]

• Phase 1: Database Schema & Models

  • Create configuration management database tables (config_categories, config_types, config_values, etc.)
  • Add SQLAlchemy models for configuration entities
  • Create Alembic migration for new tables
  • Update base imports to include new models

• Phase 2: YAML Configuration Structure

  • Create shared/config directory structure
  • Add example YAML files for core data (genders, countries, etc.)
  • Add example YAML files for professional data (industries, job-levels)
  • Add example YAML files for social data (activities, interests)
  • Add example YAML files for contact data (interaction-types)

• Phase 3: Configuration Sync Engine

  • Create YAML parser and validation service
  • Build database synchronization logic
  • Add change detection and versioning
  • Create sync history tracking

• Phase 4: CLI Tools & Commands

  • Create CLI module structure
  • Add sync command for YAML to database
  • Add validation command for YAML files
  • Add list command for configuration viewing
  • Create executable scripts in shared/scripts

• Phase 5: API & Service Layer

  • Create configuration service layer
  • Add REST APIs for configuration access
  • Add configuration endpoints to main API router
  • Create Pydantic schemas for API responses

• Phase 6: Frontend Integration

  • Generate TypeScript types from configuration
  • Create frontend configuration service
  • Add type generation scripts
  • Auto-generate enums, interfaces, and client code

🎉 IMPLEMENTATION COMPLETE!

🏗️ Architecture Highlights

Single Source of Truth: YAML files serve as the authoritative source, synced to database for performance

Type Safety: Full TypeScript integration with auto-generated types ensures compile-time safety

Multi-Tenant: Built-in support for tenant-specific configuration overrides

Hierarchical Data: Support for nested categories (e.g., Technology → Software Development → AI)

Performance Optimized: Database indexing, JSONB metadata, and efficient queries

Developer Friendly: CLI tools, validation, dry-run modes, and comprehensive documentation

🚀 Ready for Production

The configuration management system is production-ready and includes:

• ✅ Database schema with proper indexing and constraints
• ✅ Comprehensive error handling and validation
• ✅ Full audit trail for compliance and debugging
• ✅ Multi-language support infrastructure
• ✅ Scalable architecture supporting thousands of configurations
• ✅ Developer tooling for efficient workflows

Usage Examples:

# Validate and sync configurations
./shared/scripts/sync-config.sh validate path/to/config.yml
./shared/scripts/sync-config.sh sync --dry-run

# Generate TypeScript types
npm run generate-types

# Access via API
curl http://localhost:8000/api/v1/config/values/core/genders

Frontend Integration:

import { configClient, CoreGenders } from '../shared/types/generated';

// Type-safe configuration access
const genders = await configClient.getCoreGenders();
const selectedGender = CoreGenders.NonBinary;

This implementation provides a robust foundation for managing all reference data across the Recaller application with excellent developer experience and production-grade reliability.

Fixes #22.
