Two changes that tighten how the caller-side UX handles slow or
unresponsive callees in a group call:
1. Per-peer 30-second invite timeout
Previously the caller used a single 60-second call-wide timeout: if
*any* peer answered within the window the timer was cancelled and
slow peers could remain "ringing" indefinitely. For a mid-call
invite there was no timeout at all — the invitee stayed in
pendingPeerPubKeys forever, burning a PeerConnection on the caller
side and keeping the invitee's device ringing.
CallManager now schedules an independent 30-second timer for every
peer in pendingPeerPubKeys (or Offering.peerPubKeys in the initial
offer phase). The timer is started when the peer is added to
pending — in beginOffering, initiateCall and invitePeer — and is
cancelled when the peer answers (onCallAnswered), rejects
(onCallRejected) or hangs up (onPeerHangup). On expiry the peer is
dropped from the group, a CallHangup is published to them so their
device stops ringing, and onPeerLeft fires so CallController can
dispose the per-peer PeerConnection. If the drop leaves the caller
with zero connected and zero pending peers, the call ends with
EndReason.TIMEOUT.
Callee ringing still uses the 60-second CALL_TIMEOUT_MS in
onIncomingCallEvent; the two timers now serve distinct roles.
New constant CallManager.PEER_INVITE_TIMEOUT_MS = 30_000L.
NIP-AC.md "Event Lifecycle" documents both timers.
2. Per-peer "Calling..." status in the video grid
The shared "Waiting for others to join…" banner across the top of
ConnectedCallUI is removed. PeerVideoGrid now takes a
pendingPeerPubKeys set and, for each peer still pending, routes
rendering through PeerAvatarCell with a "Calling…" status line
under the username — so it's obvious *which* participants the call
is waiting on, not just *that* it's waiting. A peer in pending
never shows as a video cell even if a stale track is still in the
map, because they haven't actually answered yet.
The voice-only path in ConnectedCallUI now also uses PeerVideoGrid
(with empty tracks/active-video) instead of the single
GroupCallPictures + GroupCallNames stack, so the per-peer status
behavior is consistent for audio calls.
Tests added in CallManagerTest:
- perPeerTimeoutEndsP2PCallWhenBobNeverAnswers
- perPeerTimeoutDropsSlowCalleeFromGroupCall
- perPeerTimeoutIsCancelledOnAnswer
- perPeerTimeoutDropsMidCallInviteeWhenNoAnswer
- perPeerTimeoutIsCancelledOnReject
- perPeerTimeoutEndsCallWhenAllCalleesIgnore
All existing CallManagerTest cases still pass unchanged.
