C4 · Rel-15
inferredOrientation inferred from the 29-series; this is not an official 3GPP stage assignment.
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.
Cross-spec traceability
Release-valid relationships
No release-valid relationships are indexed among the mapped specifications for this lens.
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-10 context
CR activity across mapped specs
Context only: these CRs target mapped specifications in Rel-10; they are not automatically attributed to the feature.
No CR activity targeting the mapped specifications is indexed for Rel-10.
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.
