Context only: these CRs target mapped specifications in Rel-7; they are not automatically attributed to the feature.
No CR activity targeting the mapped specifications is indexed for Rel-7.
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.
