[This test on roachdash](https://roachdash.crdb.dev/?filter=status:open%20t:.*TestInspectWithoutASOFSchemaChange.*&sort=title+created&display=lastcommented+project) | [Improve this report!](https://github.com/cockroachdb/cockroach/tree/master/pkg/cmd/bazci/githubpost/issues)

Start with pkg/sql/inspect/index_consistency_check_test.go around line 906 and run sql/inspect.TestInspectWithoutASOFSchemaChange with the reported race settings. Compare the captured test logs and failure at the assertion, then identify the cause of the timeout or mismatched error; done means the test reliably passes with the intended schema-change behavior.
