I would appreciate your confirmation and clarification on the following technical points regarding the News API integration.
Question 1: Handling Deleted News Articles via API
When previously distributed news articles are later deleted or withdrawn, how is this reflected in the API?
According to the News user guide, articles that have been deleted or withdrawn will have the pubStatus field set accordingly:
stat:withdrawn: Withdrawn by the content providerstat:canceled: Canceled
If pubStatus is set to stat:canceled, users—such as companies acting as authorized redistributors of Reuters news—are strictly required to remove all versions of the item from websites, caches, and other platforms.
If pubStatus is set to stat:withdrawn, the item may still be unpublished by the provider.
Conclusion (please confirm):
- If the status is 
canceled, the data source cannot be retrieved via the API again, and  users—such as companies acting as authorized redistributors of Reuters news—  are required to delete the data from their website. - If the status is 
withdrawn, the data may still be accessible via the API, depending on the provider’s decision. 
Could you please confirm whether this understanding is correct?
Question 2: About PNAC
Are there cases where PNAC includes characters other than A–Z / a–z / 0–9 (e.g., hyphens, underscores, dots, colons, slashes, symbols, non-ASCII characters)? If so, could you please provide the full set of allowed characters?
Additionally, as background to this question, I would like to confirm whether the following four elements can always be extracted when splitting a storyId using the delimiter :
- URN scheme
 - creation_date
 - PNAC
 - version
 
Question 3: About Headlines
In the response from /data/news/v1/stories/{storyId}, the field newsItem.itemMeta.title is defined as an array. Are there cases where the number of elements exceeds one?
If multiple elements exist:
- What use cases are envisioned?
 - Which element should be referenced to determine the article title?
 - Are there any selection criteria or prioritization rules we should follow?
