What
The token refresh entry point accepts the credential store and storage handle rather than looking them up, and de-duplicates concurrent refreshes separately for bare credentials versus store-backed ones. The store module existed before but was mostly reached ambiently.
Details

This is why so many function signatures grew a trailing argument in this build.
Evidence
tryCreateCredentialsStore
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
