Primary feature evidence
Topic source Work Item The reviewed topic source is not an indexed Work Item record. The source link above remains the primary evidence anchor.
Connected work
Work Items touching mapped specs These Work Items share one or more mapped specifications. Atlas does not automatically claim that every connected Work Item defines this feature.

Primary WI evolution
Change Requests linked to the primary Work Item No indexed CRs are linked to the primary Work Item at or before this release.
Rel-97 context
CR activity across mapped specs Context only: these CRs target mapped specifications in Rel-97; they are not automatically attributed to the feature.
No CR activity targeting the mapped specifications is indexed for Rel-97.
Traceability limits
What this lineage is not claiming The reviewed topic-to-specification mapping is Atlas-curated and non-normative even when its source is an official 3GPP record. When an explicit stage classification is unavailable, specification layers are inferred from the TS/TR series and are labelled inferred rather than presented as official 3GPP stage assignments. Connected Work Items and release-context Change Requests share mapped specifications; only the topic source Work Item is treated as primary evidence for the reviewed topic mapping. This is traceability evidence and navigation, not a clause-by-clause normative feature definition.
