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.

Coverage Notes

• - in Upstream means foundational; in Downstream it means nothing is built on it yet; in Last Reviewed it means no review record exists.
• PP-001 has no QC checklist yet; it is accepted by the Product Owner's stand-in.
• WF-001 and PY-001 are labels for reviewed code instances (no artifact file).
• PY-002 is the label of the reviewed converter code.
