AWhat changed
Packaged Chinese evaluation/training resources and a staged embedding recipe, then extended the family with shared dense, lexical and multi-vector retrieval heads whose integrated scores teach each head through self-distillation.
Scientific scope
Packaged Chinese evaluation/training resources and a staged embedding recipe, then extended the family with shared dense, lexical and multi-vector retrieval heads whose integrated scores teach each head through self-distillation. C-Pack original C-TEM resource names and later BGE-M3 extension are source-specific stages, not retroactively identical models. M3's integrated teacher is an empirical training choice, not guaranteed more accurate than each head. Dense, sparse and late-interaction components are inherited; full multi-vector scoring has extra cost. The retrieval method does not itself establish a medical benefit.

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
