Verdict: 1 Low
Looks good: a one-line pin bump to a valid 40-char SHA, which the kernel-e2e workflow already validates. One low concern: the fix only reaches CI-built wheels, not users installing the ^1.4.0 PyPI wheel, and this repo has no test for the new error text.

Updates the source-build kernel pin from
c58f62c(v1.4.0) to6f4b6d6, the merge commit for databricks/databricks-sql-kernel#430. A server certificate the connector must refuse now fails after one attempt, and the kernel-backend error names the verification cause instead of onlyerror sending request for url (...). This fixes AUTH-017/018 on the kernel backend in databricks/databricks-driver-test#1959. The bump also picks up databricks/databricks-sql-kernel#423 (authenticate once before resolving feature flags) and the OSV/dependency-audit fixes (#427, #428).Validation: built the pinned PyO3 wheel with
maturin build --release --locked; passed 475 unit tests (-m "not realkernel") and 8 real-kernel tests; with this branch and kernel, driver-test AUTH-017/018 pass with hard error-text assertions on both backends and mTLS AUTH-014 to AUTH-016 still pass;git diff --check.This pull request and its description were written by Isaac.
