Add on-device AI writing assistance using ML Kit GenAI APIs (Rewriting,
Proofreading) powered by Gemini Nano via Android AICore. Users can tap
the sparkle button in the compose toolbar to access tone chips (Correct,
Rephrase, Shorter, Elaborate, Friendly, Professional, More Direct,
Punchy, + Emoji) that transform their post text. Results appear in a
card with Use/Dismiss actions.
- Play flavor: MLKitWritingAssistant using on-device Gemini Nano
- F-Droid flavor: NoOpWritingAssistant stub (returns unavailable)
- WritingAssistant interface for future DVM/NIP90 integration
- AI button hidden on unsupported devices
Also fixes pre-existing exhaustive when expression in
DecryptAndIndexProcessor for GroupEventResult.Duplicate.

Implements P2P calling over Nostr relays using WebRTC for media
transport and NIP-59 Gift Wraps for encrypted signaling. No custom
server required — only public STUN servers for NAT traversal.
Protocol layer (quartz/nip100WebRtcCalls):
- 6 new event kinds (25050-25055): offer, answer, ICE candidate,
hangup, reject, renegotiate
- WebRtcCallFactory for creating and gift-wrapping signaling events
- CallIdTag and CallTypeTag for event metadata
- Events registered in EventFactory
Call state machine (commons/call):
- CallState sealed interface with full lifecycle states
- CallManager orchestrating signaling and state transitions
- Follow-gate spam prevention: only followed users can ring,
non-follows are silently ignored
Android WebRTC integration (amethyst/service/call):
- WebRtcCallSession wrapping Google WebRTC PeerConnection
- CallForegroundService for keeping calls alive in background
- IceServerConfig with default public STUN servers
- User-configurable TURN server support
Android UI (amethyst/ui/call):
- CallScreen with offering, connecting, connected, and ended states
- IncomingCallUI with accept/reject buttons
- ConnectedCallUI with mute, video toggle, speaker, and timer
- Call button added to 1-on-1 DM chat header
- ActiveCall route added to navigation

The Guardian Project's arti-mobile-ex AAR has three problems:
1. No 16KB page-aligned binaries (required for Google Play)
2. ArtiProxy's stop()+start() causes state file lock conflicts
(lock is tied to TorClient object lifetime, released only on GC)
3. ~140MB AAR size
Replace with a custom JNI bridge built from Arti source, following
BitChat's proven approach:
Build tooling (tools/arti-build/):
- build-arti.sh: Clones official Arti, compiles with cargo-ndk
for ARM64 + x86_64, NDK 25+ for 16KB page alignment
- Cargo.toml: Minimal deps with size-optimized release profile
- src/lib.rs: Custom SOCKS5 proxy with proper lifecycle:
- initialize() creates TorClient once (holds state lock forever)
- startSocksProxy() binds port and accepts connections
- stopSocksProxy() aborts listener only (TorClient stays alive)
This cleanly separates "stop routing traffic" from "destroy client"
Kotlin side:
- ArtiNative.kt: JNI declarations + ArtiLogCallback interface
- TorService.kt: Uses ArtiNative directly, start() initializes +
starts proxy, stop() only stops proxy (no lock issues)
- TorManager.kt: Restored stop() calls for OFF/EXTERNAL modes
since our native stop is now safe
Removed: arti-mobile-ex dependency from build.gradle and version catalog
Native libraries must be built separately:
cd tools/arti-build && ./build-arti.sh

Replace Guardian Project's tor-android (C Tor) and jtorctl with
arti-mobile-ex, a Rust-based Tor implementation. This eliminates
the Android Service binding complexity in favor of an in-process
ArtiProxy object.
Key changes:
- TorService: Replace ServiceConnection to org.torproject.jni.TorService
with direct ArtiProxy.Builder/start/stop API. Bootstrap state detected
via log parsing (following BitChat's pattern).
- TorServiceStatus: Remove TorControlConnection field (Arti doesn't
support jtorctl control protocol).
- RelayProxyClientConnector: Remove DORMANT/ACTIVE/NEWNYM control
signals. Arti manages its own circuit lifecycle internally.
- Dependencies: Replace tor-android + jtorctl with arti-mobile-ex 1.2.3.
TorManager's external API (status/activePortOrNull StateFlows) and all
downstream consumers (DualHttpClientManager, TorSettings, UI) are
unchanged.

Add support for NIP-77 (Negentropy Syncing) protocol messages using
the negentropy-kmp library for efficient set reconciliation between
client and relay.
New files:
- NegOpenCmd, NegMsgCmd, NegCloseCmd: Client-to-relay commands
- NegMsgMessage, NegErrMessage: Relay-to-client messages
- NegentropySession: Client-side reconciliation orchestrator
- NegentropyServerSession: Server-side reconciliation handler
- NegentropyManager: High-level sync manager with listener callbacks
Updated serializers:
- Jackson MessageSerializer/Deserializer for NEG-MSG, NEG-ERR
- Jackson CommandSerializer/Deserializer for NEG-OPEN, NEG-MSG, NEG-CLOSE
- Kotlin MessageKSerializer/CommandKSerializer for all NIP-77 types
Compatible with strfry relay's negentropy implementation via the
negentropy-kmp library which implements the same Protocol V1 spec.

Adds a MetadataStripper that removes GPS location, camera info, timestamps,
and other sensitive EXIF/metadata from images, videos, and audio files before
uploading. This protects user privacy by default.
- Creates MetadataStripper using AndroidX ExifInterface for images and
MediaMuxer for video/audio remuxing
- Adds "Strip location metadata" toggle to all upload dialogs (NewMediaView,
ChatFileUploadDialog) so users can disable stripping per upload
- Persists the setting in AccountSettings (stripLocationOnUpload, default true)
- Integrates stripping into UploadOrchestrator before compression
- Covers all upload paths: media posts, DM attachments, channel uploads,
profile pictures, list/channel metadata images
https://claude.ai/code/session_01974zpAMSRD9GeqBt9ax6XD
- Fixes incorrect aspect ratios of the AutoNonLazyGrid when multiple images exist for a single entry
- Adds Play buttons when the image fails to load so that people click and the post appears.
Remove Moko Resources dependency that blocks AGP 9.0 migration.
Migrate to built-in Compose Multiplatform Resources which is compatible
with the new KMP Android plugin.
- Remove moko-resources plugin and libraries from commons module
- Move strings.xml from moko-resources/ to composeResources/values/
- Update imports from SharedRes.strings.* to Res.string.*
- Add compose.components.resources dependency to desktopApp
- Configure resource package as com.vitorpamplona.amethyst.commons.resources
