- Add test_s3_bucket_single_object_after_duplicates to verify only one S3 object exists - Add tests for upload failure scenarios (invalid project/package, empty file) - Add tests for orphaned S3 objects and database records cleanup - Add S3 direct access helpers (list_s3_objects_by_hash, s3_object_exists, etc.) - Fix conftest.py to use setdefault for env vars (don't override container config) All 52 tests now pass.
