The README correctly states that partitions use the monthly
folder_date. It does not state thatpipelines/crawler/rf_cnpj/flows.pyrecordslast_modified_dateinRawDataSource.Updatewith%Y-%m-%d. Add this distinction to prevent operators from interpreting the daily source-update date as the partition month.Proposed clarification
O particionamento passou a ser feito pela **data de referência do arquivo na fonte** (`folder_date` — o mês/competência a que os dados dizem respeito), e não mais pela `last_modified_date` (data em que o arquivo foi modificado/gerado pela Receita Federal). Isso alinha o particionamento ao período que os dados de fato representam. + +O metadado de atualização da fonte (`RawDataSource.Update`) usa a +`last_modified_date` no formato `%Y-%m-%d`.

Commit the source update only after successful materialization.
This call records the selected source date before any download, processing, upload, or dbt step succeeds. A failed run can therefore record an update for data that was not materialized. Move commit_source_update_task to the successful end of each materialization path.
The supplied poll_source_for_update_task contract specifies that the source update is committed after materialization.

Remove the obsolete partitioning warning.
Lines 42-50 still state that partitions use the server modification date and that the reference-date correction is pending. That conflicts with Lines 28-30. Update or remove the stale risk and issue text so operators receive one consistent procedure.

Do not default url to None.
requests_url requires a str, but get_api_metadata() permits None and passes it through on Line 48. A direct task invocation without url fails after scheduling retries. Make url required or substitute the CAFIR endpoint when it is None.

Move I/O operations out of utils.py.
requests_url, download_csv_file, and process_csv_file perform network or filesystem I/O. parse_api_metadata also writes to stdout on Line 95. Keep these operations in tasks.py. Keep only pure transformations in utils.py.
Based on learnings, helpers in utils.py must be pure and without Prefect decorators. As per coding guidelines, pipelines/datasets/*/utils.py must keep helper functions pure and without Prefect decorators.

Raise download errors and set a timeout.
requests.get(url) has no timeout. A stalled source can block a Prefect worker indefinitely. download_csv_file only logs HTTP failures and returns normally, so download_file is marked successful and its configured retries do not run. Pass a finite timeout and call response.raise_for_status() before writing the file.
