      • What was accomplished since the last update?
        • Added CSOT support to OIDC; the PR was reviewed, approved, and merged.
        • Fixed a bug where waitQueueTimeoutMS was not ignored when timeoutMS was set. Raised a PR, which is currently under review.
        • Started investigating a flaky MultiBatch_bulkWrites test, suspected to be caused by a bug in our transport layer (TlsChannelImpl).
      • What's the focus over the next two weeks?
        • Get the bug fix PR for waitQueueTimeoutMS approved and merged.
        • Continue troubleshooting to identify the root cause of the transport layer issue.
        • Address flaky tests related to JAVA-5375, determining whether they are true bugs or just unstable tests that require retries or refactoring.
      • Any risks/blockers/impediments?
        • Nothing.
      •  Anything else you think is worth highlighting to stakeholders?
