🛡️ Sentinel: Unbounded String DoS in TableEntry & Privacy Obfuscation in IndeterminateProgressBar

[manupawickramasinghe]

🎯 Focus: Security Patch and Iterative Enhancement

💡 Context: As the application scales and supports larger CSV data imports, unbounded text fields pose a risk for Denial of Service via UI layout exceptions when rendered in IntrinsicColumnWidth(). Additionally, maintaining the momentum of the privacy obfuscation feature, all charts and progress components must handle temporary reveals.

🔧 Fix/Addition:

• Implemented defensive truncation (500 character limit) to the headers and firstEntry fields inside budget/lib/widgets/tableEntry.dart to ensure stable UI rendering.
• Refactored IndeterminateProgressBar in budget/lib/widgets/globalLoadingProgress.dart into a StatefulWidget equipped with touch gesture listeners (Listener), haptic feedback, and a 2-second auto-collapse timer to force the progress bar visually to 0.0 when global amount obfuscation is enabled.

📈 gemini.md Status: The gemini.md file has been updated to reflect the completion of the privacy obfuscation feature across all widgets, and the "Unbounded String Rendering DoS" vulnerability was logged under "Critical Security Learnings."

✅ Verification: Run flutter analyze and flutter test. Tested and passed natively.
