 """Utility script to trigger the training workflow end-to-end for testing.
 
-Steps performed:
+Steps performed (default):
 1. Upload the CSV test dataset to MinIO using the configured `mc` alias.
 2. Insert a new experiment_run record in Postgres and capture the generated ID.
 3. Trigger the Temporal `train_model` workflow with the correct payload.
 
-Prerequisites:
+Local diagnosis (--local / --validate-only):
+- --validate-only: Validates scenario parameters only (no MinIO, Postgres, Temporal).
+- --local: Runs the same training pipeline locally (validate + load CSV + train +
+  after_train_calculation). Use to get full Python tracebacks for debugging.
+  Does not upload to MinIO, insert DB, or start Temporal. By default skips
+  MLflow save; use --local-save-mlflow to also test saving to MLflow.
+
+Prerequisites (default flow):
 - `mc` CLI configured with alias defined in MINIO_ALIAS.
 - PostgreSQL accessible with credentials in environment variables or defaults.
 - Temporal server reachable without TLS on TEMPORAL_HOST / TEMPORAL_NAMESPACE.
