Traceability Review¶
Example purpose¶
This artifact records the ES-108 traceability review.
Traceability ensures that integrated changes are not arbitrary code changes. Each change should connect to a work item, LMU requirement, design source, implementation evidence, and verification status.

Untraceable changes¶
None identified.
Traceability gaps¶
| Gap | Work Item | Downstream Defect / Risk | Required Follow-Up |
|---|---|---|---|
| Additional verification needed for invalid status transitions. | IW-004 | DEF-001 | Add ES-109 status-transition tests. |
| Additional denied-action tests required. | IW-005 | DEF-002 | Add ES-109 access-control matrix tests. |
| Focused review required for evidence write failure behavior. | IW-007 | DEF-003 | Add ES-109 failure-path tests and architecture review. |
| Emergency/prohibited category handling needs focused verification. | IW-007 | DEF-004 | Add ES-109 Campus Safety boundary test. |
| Build/test command evidence not finalized. | Integration verification | DEF-005 | Formalize ES-109 command evidence. |
Review decision¶
Traceability accepted with gaps carried forward to ES-109 testing focus.
The implementation increment is traceable enough to integrate conditionally because no untraceable changes were identified and all gaps are visible.
