## Purpose

Tracks backward/forward links between artifact instances so that the Business Case's
cross-artifact traceability success criterion is measurable. A row is added or
updated whenever an artifact instance is created or reviewed.

## Open Inconsistencies

## Coverage Notes

- No instance exists yet of the other artifact types (KPI, BMC, BPMN, UCD, US, UC, design artifacts, TP, GOV, DICT); the tasks of all milestones are plain technical tasks.
- `-` in Upstream means foundational; in Downstream it means nothing is built on it yet.
