Code Review
This pull request primarily updates the manifest.json to separate the data download and processing steps, which is a good improvement for modularity. However, I've identified a critical issue in preprocess.py where the script fails if no input files are present. This should be addressed to make the script more robust, especially with the newly separated execution steps.

This condition has a couple of issues:
- Critical Bug: If
total_files_to_processis 0 (i.e., no input files), this condition evaluates toFalse. This incorrectly triggers theelseblock on line 1068, causing a fatal error. The script should handle the case of zero input files gracefully instead of failing. - Maintainability: The use of the bitwise
&operator for what appears to be a logical condition is confusing and error-prone. It works here due to Python's operator precedence and chained comparisons, but it's not idiomatic and could easily lead to bugs if this line is modified in the future. You should use the logicalandoperator for clarity.

The logic to kill the script is intentionally kept (to make sure existing URLs are responding).
