KEY FEATURES DOCUMENTED
================================================================================

VendorRegistry:
- Thread-safe singleton with double-checked locking pattern
- Centralized vendor registration and management
- Priority-based routing for method selection

Documentation for Issue #11 (Vendor Registry System) has been successfully
updated across CHANGELOG.md and docs/api/dataflows.md.

The documentation comprehensively covers:
- All core components and their functionality
- Usage patterns with working code examples
- Custom vendor implementation guide
- Thread safety and concurrency details
- Error handling and retry logic
- Rate limiting configuration
- Test coverage across all components

All documentation changes have been validated for:
- Accuracy (cross-references verified)
- Completeness (all components documented)
- Consistency (style and format aligned)
- Quality (examples are practical and runnable)

The vendor registry system provides a robust, production-ready framework for
centralized vendor management with automatic rate limiting, thread-safe
operations, and standardized vendor interfaces.

Status: READY FOR PRODUCTION
