r-dash-db-integration-tests-skip-on-postgres-creds-mismatch

R-Dash integration tests auto-skip or error when Postgres credentials are mismatched in the environment — this is a pre-existing env-auth issue, not a code regression. 54 tests skipped/errored in this state across all waves. Running make up with correct DB credentials resolves this. Always distinguish creds-mismatch skips from actual test failures before declaring regressions.
