# USR-003 Requirement Relationships and Traceability
## Statement
The tool shall support parent-child relationships between requirements, enabling traceability from high-level user needs down to detailed specifications.
## Rationale
Traceability relationships enable:
- Verification that all user needs are addressed by lower-level requirements
- Impact analysis when requirements change
- Coverage reporting to ensure completeness
- Support for multiple parents to handle cross-cutting concerns (e.g., security requirements affecting multiple features)
## Acceptance Criteria
- Requirements can declare one or more parent requirements
- Parent-child relationships form a directed graph
- Relationships are bidirectional (can traverse up and down)
- Multiple parents are supported for cross-cutting requirements
- Relationship changes are tracked and detectable
