Purpose

Tracks backward and forward links between artifact instances so that the traceability of concerns to milestones is measurable. A row is added or updated whenever an artifact instance is created or reviewed.

Coverage Notes

• No design artifacts (use cases, domain model, DCD, ERD, test plan) exist: all tasks are technical tasks; - in Upstream means foundational, in Downstream that nothing is built on it yet, in Last Reviewed that no RC-* exists yet.
• Concern coverage will be rechecked when code exists (MIL-003 to MIL-007).
