What is the response if a deletion error occurs in a processing set?

When a deletion error occurs in a processing set, the appropriate response is to recognize that the integrity of the data has been compromised, rendering that specific processing set unusable for further analysis. This response is critical because any subsequent processing or analysis on a set that has a deletion error could lead to incorrect results or additional errors. Therefore, the set's status is adjusted to reflect that it cannot be further used, ensuring that any teams or systems relying on the data can avoid it to maintain accuracy and data integrity.

Contextually, it is important to note that marking the set as unusable helps maintain the integrity of the overall data processing workflow. The other options, while they might seem plausible in other contexts, do not align with best practices for handling errors. For instance, having the set put into a completed state would misrepresent the processing status and could lead to confusion. Similarly, allowing the set to be processed again or automatically archiving it without addressing the underlying issues would not resolve the data integrity problems and could further complicate data management processes.
