Wifi aware refactor mesh core (#711)
* wifi aware wip * wifi aware wip * starting to work * werk * dms work * wip * fix(wifi-aware): use bindSocket and scoped IPv6 instead of bindProcessToNetwork * Merge branch 'upstream/main' into fix/wifi-aware-socket-binding * Fix Wi-Fi Aware connectivity and UI integration post-merge - Replace bindProcessToNetwork with bindSocket for VPN compatibility. - Implement Scoped IPv6 address resolution (aware0) for mesh routing. - Bridge Wi-Fi Aware incoming messages to AppStateStore for UI visibility. - Fix syntax errors and variable name conflicts in Debug UI. * Enhance Wi-Fi Aware robustness and debug UI display - Clean up transport resources (sockets, server sockets, network callbacks) immediately on peer disconnection. - Implement resolveScopedAddress to show scoped IPv6 (e.g., %aware0) in Debug UI. - Fix Map type mismatch warning in ChatViewModel bridge. - Filter self-ID from peer cleanup tables to prevent recursive self-removal. * Share GossipSyncManager across transports to prevent redundant message synchronization - Registered BluetoothMeshService's GossipSyncManager as a singleton in MeshServiceHolder. - Modified WifiAwareMeshService to use the shared GossipSyncManager if available. - Added background cleanup for peer mappings on socket disconnection. - Fixed Kotlin type mismatch during nickname map merging. * Restore VPN acquisition logic and improve peer cleanup - Revert removal of NET_CAPABILITY_NOT_VPN to allow hardware handle acquisition while VPN is active. - Refactor handlePeerDisconnection to more reliably cleanup initial and routed IDs. - Switch cleanup logging to debug level to reduce log noise. * Fix wifi aware socket binding 2 (#536) * Background persistence (#505) * persistence step 1 * fix build * messages in the background work, notifications not yet * app state store * DM icon shows up * notification launches when app is closed! * keep ui updated * lifecycle fixes * extensive logging, maybe revert later * send nickname in announcement * quit in notification * setting in about sheet * fix quit bitchat * lifecycle fixes * power mode based on background state * stats for both direciotns * fix graph persistence * better counting * count per device * only compute when debug sheet is open? untested * fix read receipts * fix read receipts fully * fix unread badge if messages have been read in focus * foreground promotion fix * fix app kill in notification * adjust to new tor * nice * about sheet design * bump version 1.6.0 (#524) * Automated update of relay data - Sun Dec 14 06:06:53 UTC 2025 * bump targetSdk (#526) * Automated update of relay data - Sun Dec 21 06:06:56 UTC 2025 * Automated update of relay data - Sun Dec 28 06:07:12 UTC 2025 * Prevent quit notification from reappearing (#530) * shutdown sequence * Prevent quit notification from reappearing * Restrict force-finish broadcast * Cancel quit shutdown on relaunch * fix(wifi-aware): use bindSocket and scoped IPv6 instead of bindProcessToNetwork * Merge branch 'upstream/main' into fix/wifi-aware-socket-binding * Fix Wi-Fi Aware connectivity and UI integration post-merge - Replace bindProcessToNetwork with bindSocket for VPN compatibility. - Implement Scoped IPv6 address resolution (aware0) for mesh routing. - Bridge Wi-Fi Aware incoming messages to AppStateStore for UI visibility. - Fix syntax errors and variable name conflicts in Debug UI. * Enhance Wi-Fi Aware robustness and debug UI display - Clean up transport resources (sockets, server sockets, network callbacks) immediately on peer disconnection. - Implement resolveScopedAddress to show scoped IPv6 (e.g., %aware0) in Debug UI. - Fix Map type mismatch warning in ChatViewModel bridge. - Filter self-ID from peer cleanup tables to prevent recursive self-removal. * Share GossipSyncManager across transports to prevent redundant message synchronization - Registered BluetoothMeshService's GossipSyncManager as a singleton in MeshServiceHolder. - Modified WifiAwareMeshService to use the shared GossipSyncManager if available. - Added background cleanup for peer mappings on socket disconnection. - Fixed Kotlin type mismatch during nickname map merging. * Restore VPN acquisition logic and improve peer cleanup - Revert removal of NET_CAPABILITY_NOT_VPN to allow hardware handle acquisition while VPN is active. - Refactor handlePeerDisconnection to more reliably cleanup initial and routed IDs. - Switch cleanup logging to debug level to reduce log noise. --------- Co-authored-by: GitHub Action <action@github.com> Co-authored-by: aidenvalue <> * Fix wifi aware routing (#534) * Background persistence (#505) * persistence step 1 * fix build * messages in the background work, notifications not yet * app state store * DM icon shows up * notification launches when app is closed! * keep ui updated * lifecycle fixes * extensive logging, maybe revert later * send nickname in announcement * quit in notification * setting in about sheet * fix quit bitchat * lifecycle fixes * power mode based on background state * stats for both direciotns * fix graph persistence * better counting * count per device * only compute when debug sheet is open?
