azure-cosmos-db-py

The fragment presents a coherent, legitimately-scoped approach to implementing a Cosmos DB client with dual authentication for production and local emulator development. It uses standard PyPI packages, environment-based secrets, and a singleton service pattern consistent with the described architecture. While care should be taken to ensure emulator credentials are not leaked to production environments, the footprint is proportionate to the stated purpose and does not exhibit observable malicious behavior or exfiltration patterns.
