##### Insert a new experiment run

```sql
-- Optional: remove a previous run with the same id
DELETE FROM public.experiment_run WHERE experiment_run_id = 1001;
```

```sql
INSERT INTO public.experiment_run
(experiment_name, run_name, username, status, error_message, created_at,
updated_at, bucket_name, file_name, request_data, orchestrator_response_data)
VALUES(
	'test-experiment-name',
	'test-run-name',
	'test-username',
	'ORCHESTRATOR_WAITING_PROC',
	null,
	now(),

	'model-training',
	'training_data.csv',
	'{"experiment_run_id":1001,"variable_columns":["feature_a","feature_b"],"target_variable":"target","bucket_name":"model-training","file_name":"training_data.csv","line_separator":",","decimal_separator":".","train_size":80,"shuffle":true,"model_name":"Linear Regression","model_type":"linear_regression","data_model_kwargs":{"lag_train":{"feature_a":0,"feature_b":0},"lag_val":{"feature_a":0,"feature_b":0},"nan_treatment":"drop"},"model_kwargs":{"degree":1,"scaler_name":"Standard Scaler"},"opt_params":{}}',
  null
);
```

##### Upload the input dataset to MinIO

```bash
mc cp input_dataset.csv suse/model-training/training-sample-dataset-1001.csv
```

##### Temporal input payload sample

Keys match `TrainModelParams.from_dict` in `model_manager/utils/models/train_model_params.py`: every field passed to `_check_none` must be present, including **`date_column`**; `model_metadata` must be non-empty for `validate_business_rules()`. You may omit **`date_format`** (defaults to `yyyy-MM-dd HH:mm:ss`). Omit optional keys (`random_state`, `val_file_name`, `model_id`) when defaults or `None` apply.
