# Dynamic Toolset Service - Business Requirement Mapping

**Service**: Dynamic Toolset Service
**Version**: 1.0
**Last Updated**: November 8, 2025
**Total BRs**: 8 umbrella BRs (26 granular sub-BRs)

---

## 📋 Overview

This document maps high-level business requirements to their detailed sub-requirements and corresponding test files. It provides traceability from business needs to implementation and test coverage.

### BR Hierarchy Structure

**Dynamic Toolset Service uses a hybrid BR structure**:
- **8 Umbrella BRs** (BR-TOOLSET-021, 022, 025, 026, 027, 028, 031, 033): High-level business capabilities documented in `BUSINESS_REQUIREMENTS.md`
- **26 Granular Sub-BRs** (BR-TOOLSET-010 to BR-TOOLSET-035): Detailed technical requirements referenced in test files

**Why This Structure?**
- **Umbrella BRs**: Provide business-level understanding (e.g., "Automatic Service Discovery")
- **Granular Sub-BRs**: Enable precise test traceability (e.g., "Prometheus Detector", "Grafana Endpoint URL Construction")
- **Dual Mapping**: Some BRs appear in both levels for backward compatibility (e.g., BR-TOOLSET-021, BR-TOOLSET-022, BR-TOOLSET-033)

**Complete Sub-BR Mapping**: See `BUSINESS_REQUIREMENTS.md` → "Sub-BR Mapping" section for full umbrella → granular traceability.
