The Offering, Ended, Connected, and PipConnected call states were showing
the logged-in user's picture alongside other call members. IncomingCall and
Connecting already filtered correctly. Now all states consistently exclude
the current user via `- accountViewModel.account.signer.pubKey`.

Replaces the single-PeerConnection architecture with full mesh topology
where each participant maintains one PeerConnection per peer, as
specified by NIP-AC.
WebRtcCallSession: Refactored to a pure PeerConnection wrapper that
accepts a shared PeerConnectionFactory. No longer manages media sources,
tracks, or camera — those are now shared across all peer sessions.
CallController: Manages per-peer sessions via ConcurrentHashMap. Shared
resources (PeerConnectionFactory, EglBase, audio/video sources, camera)
are initialized once and reused. Each peer gets its own WebRtcCallSession
with per-peer ICE candidate routing. Supports callee-to-callee mesh
connections with pubkey-based tie-breaking to avoid ofer glare.
CallManager: New methods for per-peer offer/answer publishing
(publishOfferToPeer, publishAnswerToPeer, beginOffering). Forwards ALL
answers to CallController (not just the first). New callbacks
onNewPeerInGroupCall and onMidCallOfferReceived for mesh setup. Handles
mid-call offers (same call-id) when already in Connecting/Connected state.
AccountViewModel: Updated callback wiring to pass peer pubkey with
answer events and register new group call callbacks.

Two bugs caused WebRTC group calls to get stuck in "Connecting":
1. CallController.onLocalIceCandidate() used currentPeerPubKey() which
returns only the first peer via firstOrNull(). ICE candidates were
gift-wrapped to only one peer; the others never received them.
Fixed by iterating over all currentPeerPubKeys().
2. CallManager.acceptCall() set Connecting.peerPubKeys to groupMembers
which includes the local user's own pubkey. This caused
currentPeerPubKey() to potentially return self, sending ICE
candidates to oneself instead of the caller.
Fixed by filtering out signer.pubKey from the peer set.

1. Filter out the logged-in user from the Connecting state UI, matching
the existing behavior in IncomingCall state.
2. Change GroupCallNames default textColor from Color.Unspecified to
MaterialTheme.colorScheme.onSurface so names are visible in dark mode
(Box+background doesn't set LocalContentColor like Surface does).

In group calls (e.g. Alice calls Bob and Charlie), when Bob accepts the
call, a CallAnswerEvent is gift-wrapped to all group members including
Charlie. Charlie's CallManager, still in IncomingCall state, was treating
ANY CallAnswerEvent as "answered elsewhere" (intended for multi-device
scenarios) and ending the call prematurely.
The fix checks whether the answering/rejecting peer is actually the
current user (signer.pubKey) before treating it as an "answered/rejected
elsewhere" event. If it's a different group member, we simply ignore it
and keep ringing.

Adds debug logging across CallManager, CallController, and WebRtcCallSession
to trace the full call lifecycle: SDP offer/answer creation, remote description
set success/failure, ICE candidate exchange, ICE connection state transitions,
and signaling state changes. The noOpSdpObserver is replaced with a logging
observer so setRemoteDescription success/failure is visible in logcat.
Filter logcat with: CallManager|CallController|WebRtcCallSession

Hardware bitmaps cannot be efficiently read for pixels, which is required
when parceling notifications. Adding allowHardware(false) to all image
requests used for notification bitmaps prevents the slow pixel readback.

The group factory methods work correctly with any number of members,
including single-peer calls. Remove the if/else branches that
duplicated P2P vs group logic in acceptCall, rejectCall, hangup,
sendRenegotiation, and sendRenegotiationAnswer.

Adds a security setting to hide posts with more than X hashtags (t tags),
defaulting to 5. Applied at the feed filter level via FilterByListParams.match()
and Account.isAcceptable() to cover all feeds. Configurable in Security Filters
settings, with 0 to disable.

Full-mesh WebRTC group calls degrade at 5+ participants (each
participant uploads N-1 streams). Hide the voice and video call
buttons in the chat header when the room has more than 5 members.

- Add recipientPubKeys() and groupMembers() helper methods to
CallAnswerEvent, CallHangupEvent, CallRejectEvent, and
CallRenegotiateEvent (matching the existing pattern in CallOfferEvent)
- Document in NIP-AC spec that group calls handle multi-device
self-notification implicitly by including the sender's own pubkey
in the gift-wrap recipient set
https://claude.ai/code/session_013h2E7spwHDgSjunqumsYgp
SDP payloads (offer, answer, renegotiate) are specific to individual
PeerConnections and cannot be shared across peers. This commit:
- Adds group-context overloads to createCallOffer, createCallAnswer,
and createRenegotiate that include all member p-tags but wrap to
a single target peer
- Removes createGroupRenegotiate (renegotiation is always per-peer)
- Updates sendRenegotiation/sendRenegotiationAnswer to take explicit
peerPubKey and use per-peer wrapping with group p-tags
- Updates invitePeer to include all existing group members + invitee
in p-tags so the new peer sees the full group composition
- Documents SDP per-peer vs sign-once distinction in NIP-AC spec
https://claude.ai/code/session_013h2E7spwHDgSjunqumsYgp
All signaling event types in group calls (answer, hangup, reject,
renegotiate) now include p-tags for every group member, matching the
pattern already used by CallOfferEvent. This allows signing the inner
event once and gift-wrapping it separately for each recipient.
- Add Set<HexKey> build() overloads to CallAnswerEvent, CallHangupEvent,
CallRejectEvent, and CallRenegotiateEvent
- Add createGroupCallAnswer, createGroupRenegotiate factory methods
- Fix createGroupHangup to sign once instead of per-peer
- Update createGroupReject to accept full member set
- Update CallManager to use group methods when in group call
- Document group call p-tag convention in NIP-AC spec
- Add tests for all group build overloads
https://claude.ai/code/session_013h2E7spwHDgSjunqumsYgp
- Include pending peers in hangup notification so ringing users get
immediate feedback instead of waiting for the 60s timeout
- Sign individual hangup events per peer with correct p-tag instead
of reusing a single event with the first peer's tag
- Stop treating ICE DISCONNECTED as terminal; only hang up on FAILED
since DISCONNECTED is often transient (network switch, packet loss)
- Send "busy" reject when receiving a call while already in one

RingtoneManager.getRingtone() and audio mode switching do disk I/O,
causing StrictMode DiskWriteViolation when called from the state
collector on the main thread. Wrap startRinging() and
switchToCallAudioMode() in withContext(Dispatchers.IO).
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
Add ability to invite new users into an ongoing call:
- CallManager.invitePeer() sends a call offer to a new peer using
the current callId, adding them to pendingPeerPubKeys
- CallController.invitePeer() exposes this to the UI layer
- Add PersonAdd button to connected call controls
- Add AddParticipantDialog with user search (reuses UserSuggestionState)
- New strings: call_add_participant, call_search_users
Rewrite CallScreenPreviews to showcase all call states:
1. Offering P2P call (Calling...)
2. Offering group call (3 avatars)
3. Connecting
4. Incoming voice call
5. Incoming video call
6. Incoming group call (4 avatars)
7. Connected P2P voice call with controls
8. Connected muted + video + speaker
9. Connected group call with pending peers
10. Connected with Bluetooth audio
11. Call ended
12. Large group (5+ members, +N badge)
13. PiP calling
14. PiP connected
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
The call now starts immediately when the first peer answers instead
of waiting for all participants. Remaining peers are tracked as
pending and shown in the UI with a "Waiting for others to join..."
indicator. When a pending peer answers, they move to the connected
set. If a pending peer rejects or hangs up, they're silently removed.
Changes:
- Add pendingPeerPubKeys to Connecting and Connected states
- Add allPeerPubKeys helper on Connected for UI rendering
- Split peers into connected/pending on first answer in onCallAnswered
- Handle subsequent answers in Connecting and Connected states
- Carry pending peers through Connecting -> Connected transition
- Show all peers (connected + pending) in call UI avatars
- Display "Waiting for others to join..." when pending peers exist
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
When a peer hangs up or rejects in a group call, remove them from the
participant set instead of ending the entire call. The call only ends
when no peers remain (all others left). Similarly, if a peer rejects
during the Offering phase of a group call, remove them but continue
ringing remaining peers.
For incoming group calls, if the original caller hangs up the call
ends immediately. If another group member leaves, the call continues
as long as at least 2 members (including self) remain.
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
- Add GroupCallPictures composable showing up to 4 user avatars in
a grid layout (same pattern as NonClickableUserPictures in chat)
- When >4 members, show 3 avatars + a "+N" badge in the 4th slot
- Add GroupCallNames composable showing up to 2 names + "+N" remaining
- Update CallInProgressUI, IncomingCallUI, ConnectedCallUI, PipCallUI,
and PipConnectedCallUI to pass full peerPubKeys/groupMembers sets
instead of only .first()
https://claude.ai/code/session_01LR8NmFGdMoDTVcfKjL7HWR
- Add MODIFY_AUDIO_SETTINGS for audio routing (speaker, earpiece, BT SCO)
