Run Deepchecks suites (data integrity, train-test validation, model evaluation) on tabular / NLP / vision data + models. Pass `result.passed_conditions()` to CI to gate on regressions; the same checks run during research, CI, and production monitoring per the Deepchecks lifecycle posture. Use before training to catch train-test leakage and data-integrity defects in a tabular, NLP, or vision dataset, and to re-run the same suite on production samples to detect drift.
