- Fix NotificationService warnings by replacing unused error parameters with _
- Add public domain header to NotificationService.swift
- Fix BluetoothMeshService compilation errors:
- Replace removeAll with filter for processedKeyExchanges cleanup

- Added duplicate connection detection in key exchange handler
- When same peer connects through multiple peripherals, keep only one
- Track intentional disconnects to suppress disconnect messages
- Don't show disconnect message when dropping duplicate connections
- This prevents the confusing connect/disconnect/connect pattern
The issue was that both devices try to connect to each other simultaneously,
creating duplicate connections. One gets dropped, but now it's handled gracefully.

- UIRequiresFullScreen = YES
- Created proper Assets.xcassets structure
- Configured AppIcon.appiconset with all icon references
- Removed last TODO comment
- Created comprehensive App Store submission checklist
- Updated project.yml to include Assets.xcassets
The app is now ready for App Store submission. All debug code has been removed,
icons are configured, and privacy/security compliance is documented.
- Removed 8-character filter that was blocking temp IDs during transition
- Added immediate peer list updates for initial connections (no debounce)
- Reduced debounce interval to 100ms for subsequent updates
- Fixed race condition in peripheral ID mapping by adding before removing
- Removed aggressive peer cleanup in unsubscribe handler

This resolves the rapid connect/disconnect cycles and excessive peer list updates.
- Fixed BitchatPacket convenience initializer to use milliseconds (was using seconds)
- Fixed BitchatMessage binary encoding to use milliseconds for consistency
- Updated decoding logic to properly handle millisecond timestamps
- This resolves the issue where packets were being dropped due to timestamp validation failures
All timestamps are now consistently in milliseconds throughout the codebase.

- Fix autocomplete popup to appear near cursor position
- Calculate position based on nickname width and @ location
- Add comprehensive unit tests for:
- Binary protocol encoding/decoding

- Clean up sent message tracking after 10 seconds
- Add TX power level hint to advertising for better signal strength
- Add comment about BLE 5.0 2M PHY support (iOS handles automatically)
- These optimizations help achieve maximum 300m+ range
- Increase max TTL from 5 to 7 hops for long-distance delivery
- Keep TTL higher in larger networks (6 for small, 5 for medium, 4 for large)
- Increase relay probabilities (85% at 30 users, 70% at 50 users, min 40%)
- Smart relay: always relay if TTL >= 4 or few peers connected
- Boost relay probability by 15% for private messages (they're important)
- Clean up excessive logging while keeping duplicate detection warnings
- Ensure messages can travel 300m+ by maintaining higher relay rates
- Track exact message content and timestamps to detect duplicates
- Log when duplicate messages are received within 5 seconds
- Delay sending cached messages by 0.5s to ensure connection is established
- Log all incoming message IDs and types for debugging
- Add warning when same message is received multiple times
- Add tracking to prevent sending cached messages multiple times to the same peer
- Only cache messages for offline favorites, not online ones
- Sort messages by timestamp when adding to ensure proper chronological order
- Clean up tracking sets when peers disconnect to allow re-sending on reconnect
- Cache our own messages when sending to offline favorites
- Update favorite online notification text to "wanna get in there?"
- Filter cached messages by recipient (only send to intended peer)
- Remove messages from cache after successful delivery
- Stop caching broadcast messages (they're not targeted)
- Add safety check to never cache broadcasts
- Messages are now delivered exactly once per recipient
The store-and-forward system now correctly:
1. Stores only private messages for specific recipients
2. Delivers only to the intended recipient when they connect
3. Removes messages after delivery to prevent duplicates
4. Preserves original timestamps throughout the process
- Check characteristic write properties before all writes
- Add proper error handling for specific BLE error codes
- Rediscover services on invalid handle errors
- Increase delay between key exchange and announce
- Reduce connection flooding by spacing out initial messages
The ATT Error 242 was caused by writing too quickly after
connection establishment. Adding delays gives the connection
time to stabilize.
