The useful question

Which contracts participated in this transaction?

Read the receipt and captured events. Where a trace is available, inspect the nested calls and their outcomes before interpreting the apparent transfer sequence.

Where the evidence stops

Available call and historical-state coverage varies by provider. A missing record does not establish that an action never occurred.
