Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Inconsistent propagation of the `ExpectedBucketOwner` parameter to internal multipart and copy operations can allow attackers to hijack uploads via bucket sniping. Developers must ensure that all sub-operations (such as part uploads and completion requests) inherit this ownership check validation constraint.
