π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

There was a problem hiding this comment.
π Info: Broad except does not mask HTTPException
Widening to except Exception in _validate_pdf_structure cannot swallow an HTTPException: the magic-byte 415 is raised before the try, and the only in-try raise is ValueError, already intended to become 415. All other structural failures now map to 415 as intended.
