Jira issue: CRDB-67913

Start with `pkg/ccl/testccl/sqlccl/sqlccl_test` and the failing `TestReadCommittedReadTimestampNotSteppedOnCommit` test; the trace points to `read_committed_test.go:250`. Reproduce the failure on the cited basalt-26.3 commit and inspect the test’s expectations and trace. Done means identifying and fixing the cause so the test passes reliably; the issue provides no specific expected change.
