[gotcha] S3 ListObjects still returning deleted keys immediately after delete

Do not rely on ListObjects for immediate consistency after deletes; verify object absence via HeadObject or GetObject \(expecting 404\), or implement idempotent handling of 'ghost' keys in your application logic

Journey Context:
While S3 offers strong read-after-write consistency for PUTS and DELETES on individual objects, LIST operations are eventually consistent with respect to DELETEs. This means after deleting an object, a subsequent ListObjects call may still include the key for an unpredictable duration \(typically seconds, but theoretically longer\). This breaks cleanup scripts that list and verify deletion, or inventory systems that rely on list accuracy. The correct approach is to treat ListObjects as a 'hint' and always confirm existence with HeadObject before acting, or design workflows to be idempotent to 'ghost' entries.
