- Added SecureNotificationManager with cross-browser support (Chrome, Firefox, Safari, Edge)
- Integrated WebRTC message notifications with tab visibility detection
- Implemented XSS protection, URL validation, and rate limiting
- Notifications shown only when chat tab is inactive
- Enforced HTTPS and user gesture requirements
- Deleted BluetoothKeyTransfer.js and related classes
- Removed BluetoothKeyTransfer.jsx UI component
- Cleaned up Bluetooth imports from app-boot.js and bootstrap-modules.js
- Removed Bluetooth buttons and handlers from main app
- Eliminated all Bluetooth functionality due to Web Bluetooth API limitations
- Browsers cannot create GATT servers or advertise devices
- Reduced bundle size by ~78KB
- Application now focuses on supported browser technologies (QR codes, manual key exchange, WebRTC)

- Reduced bundle size by ~78KB
- Application now focuses on supported browser technologies (QR codes, manual key exchange, WebRTC)
- Cache only essential PWA assets (manifest, icons, core scripts)
- Use Network First for all other requests
- Remove aggressive caching of UI components and styles
- Preserve PWA installation while minimizing cache footprint
- Fix duplicate chunk detection by using data hash instead of index
- Add comprehensive logging for QR scanner debugging
- Implement proper buffer cleanup when scanner is closed
- Preserve original binary data instead of decoding to JSON
- Add deduplication logic to prevent same QR code being processed multiple times
- Improve error handling and scanner state management
- Fix binary chunk reconstruction to maintain SB1:bin: prefix format
- Replaced original JSON with minimized binary format (gzip + base64).
- Adjusted rendering and QR code generation for compatibility.
- Reduced payload size for improved efficiency.
- removed all logging of raw IV, JWK, session tokens, verification codes
→ logs now only include error codes, timestamps and short non-reversible SHA-256 hashes (first 4 bytes)
- replaced global master key storage with PBKDF2-derived non-extractable AES key
→ master key lives only in session memory and is cleared on timeout/focus-out
- added password-based derivation (PBKDF2) for master key initialization
- migrated persistent key storage to AES-GCM wrapped ciphertext in IndexedDB
→ JWK export → encrypt with session master key → store ciphertext + IV + metadata
→ unwrap + import as non-extractable on restore
- removed busy-wait loops and direct `window.gc()` calls
→ replaced with async non-blocking cleanup via setTimeout/Promise/WebWorker
- Updated connection flow between users via QR codes
- Added manual switching option in QR code generator
- Increased number of QR codes for better readability
- Removed session creation and Lightning payment logic
- Refactored security system:
* no more restrictions
* all systems enabled on session creation
- Improved QR code exchange for mobile devices
Replace CDN React/ReactDOM/Babel with local libs; remove Babel and inline scripts
Build Tailwind locally, add safelist; switch to assets/tailwind.css
Self-host Font Awesome and Inter (CSS + woff2); remove external font CDNs
Implement strict CSP (no unsafe-inline/eval; scripts/styles/fonts from self)
Extract inline handlers; move PWA scripts to external files
Add local QR code generation (qrcode lib) and remove api.qrserver.com
Improve SessionTypeSelector visual selection (highlighted background and ring)
Keep PWA working with service worker and offline assets
Refs: CSP hardening, offline-first, no external dependencies
