👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 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.

🎯 What: The
⚠️ Risk: The previous reliance on
Math.random()call used for fallback UUID generation infallbackUuidinsrc/ShapeClipboard.tshas been replaced with a cryptographically secure equivalent viacrypto.getRandomValues().Math.random()exposed an Insecure Randomness vulnerability. SinceMath.random()does not provide true cryptographic randomness, generated UUIDs could theoretically be predictable or lead to collisions, posing a risk when reliable uniqueness is essential (e.g., across collaborations or syncing).🛡️ Solution: The UUID generation now passes down the
cryptoAPI properly (prioritizing the Obsidian window's secure engine, then the generic DOMwindow, and optionallyglobalThis.cryptofor headless environments). It securely instantiates an array and derives unbiased pseudorandom bytes.Math.random()is retained explicitly only as an absolute last resort whencryptois undefined so uniqueness guarantees gracefully degrade rather than silently failing to zero arrays.PR created automatically by Jules for task 9417972830518485790 started by @MarsLuay
