What

When a login token refresh cannot get its lock in time, the failure is now classified as oauth_refresh_lock_timeout rather than falling into the generic bucket, and it is logged the same way as auth errors and revoked tokens. Unconditional.

Evidence

oauth_refresh_lock_timeout

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
