Tool inspector
replace_story_media
Replace an attached media asset in one action (e.g. swap an expired-rights image for a valid one). Detaches the old asset and attaches the new one, preserving caption and lead-image status; alt text resets because the image content changed — pass altText to set it in the same call. Returns the updated story.
