Click **Validate**. If a report appears, use its exact paths to repair the + Quiz and update the file and field.

Directory paths, `http://`, protocol-relative URLs, and `data:` URLs are invalid. +- A video is `{ provider: "youtube", id, start?, placement? }`. Use the bare 11-character YouTube id. Optional `start` is a non-negative whole number of seconds. - `placement` is `"question"` or `"explanation"`. Omit the default `"question"`. Put answer-revealing media under `"explanation"` and avoid revealing the answer through question-side alt text or captions. -- Verify every Image source and YouTube id exists and matches the intended content.
