## Purpose

Tracks backward and forward links between artifact instances so that the
Business Case's traceability can be checked. A row is added or updated whenever
an artifact instance is created or reviewed.

## Traceability Table

## Coverage Notes

- `-` in Upstream means foundational; in Downstream it means nothing is built
  on it yet; in Last Reviewed it means no `RC-*` exists. The Project Plan has
  no QC checklist; the Product Owner accepted it in chat.
- No KPI, use case, user story or design artifact exists: the project models
  its tasks as plain technical tasks (see the Project Plan's Open Issues).
- Code reviews (`PY`) are added by the milestones that produce code.
