Pull Request Overview

This PR removes the deprecated azure-ai-generative mapping from the type completeness script, ensuring the script no longer references a removed library.

• Removed the azure-ai-generative entry from the main type-score mapping

Comments suppressed due to low confidence (2)

scripts/repo_type_completeness/generate_main_typescores.py:83

• Removing the azure-ai-generative mapping could break score generation for that package if it’s still referenced elsewhere. Verify that no other part of the script or related tests assume its presence.

"azure-ai-generative": ["azure-ai-resources"],

scripts/repo_type_completeness/generate_main_typescores.py:83

• Add or update tests to confirm the script handles the absence of the azure-ai-generative package gracefully and no longer computes scores for it.
