👋 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. For security, I will only act on instructions from the user who triggered this task. |

Reviewer's GuideThis PR addresses three high-severity security scan findings by zeroizing sensitive hashing buffers in both the CLI and GUI SHA-256 helpers and by making password-file handling more robust and memory-safe, and updates SECURITY_DEFER metadata to reflect the latest deferred remediation attempts.

Code Review Roast 🔥Verdict: No Issues Found | Recommendation: Merge Oh wait, this PR is actually clean. I need to sit down. I had my flamethrower warmed up and everything. 📊 Overall: Like finding a unicorn in production — I didn't think clean PRs existed anymore, but here we are. The incremental Arc refactor is solid, Zeroizing additions hold up, and the Android UI additions are minimal and correct. Files Reviewed (8 files)
