What changed
Content types in their own REST namespace can be discovered. Missing total-count headers no longer lead to a guessed complete inventory, and unavailable types are identified. Service-page filtering no longer incorrectly rejects an otherwise valid Pages import.
Why it matters
More of your article inventory can reach the workspace for selection and analysis.
In your workflow
Add your website, review the discovered articles, then select the content you want to analyse. Importing the inventory is separate from running analyses.
