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.

- 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
https://claude.ai/code/session_01HpowdWMK77pA35ABn9XWpD
Extends the NIP-AC P2P call signaling to support group calls by
sending individual gift-wrapped offers to each member of the group,
all sharing the same call-id.
- CallOfferEvent: add multi-pubkey build overload, groupMembers(),
isGroupCall(), and recipientPubKeys() helpers
- WebRtcCallFactory: add GroupResult type, createGroupCallOffer(),
createGroupHangup(), and createGroupReject() methods
- CallState: change peerPubKey to peerPubKeys (Set<HexKey>) across
Offering, Connecting, Connected, and Ended states; add groupMembers
field to IncomingCall
- CallManager: add initiateGroupCall() that creates a single signed
offer with p tags for every callee and gift-wraps it individually;
hangup sends to all peers in a group call
- CallController: add initiateGroupCall() entry point
- Tests: add group call offer tests for p tags, call-id, call-type,
and expiration

The code implements two protocol features not previously documented in
the NIP: (1) renegotiation responses use CallAnswer (kind 25051) to
complete the SDP handshake, and (2) self-addressed answer/reject events
notify other devices of the same user to stop ringing.
https://claude.ai/code/session_01XSjhzuVn8N4Q2hZAYMRGqM
Adds an ephemeral variant of GiftWrap for transient encrypted messages
that relays don't need to persist. EphemeralGiftWrapEvent extends
GiftWrapEvent so all existing processing paths (decryption, routing,
notifications, call signaling) automatically handle it via type
hierarchy. Relay subscription filters are updated to request both kinds.
https://claude.ai/code/session_0157X96G6HLTzYxkdX9pyTSJ
Major additions to the NIP specification:
- Gift wrap expiration: documented that outer gift wraps MUST
include expiration tags so relays can garbage-collect signaling
- Event structures: added full JSON examples with all required
fields (pubkey, id, sig, expiration, alt tags)
- ICE candidate buffering: documented that candidates MUST be
buffered while ringing and NOT cleared on accept
- Staleness and deduplication: documented 20s staleness check
and event ID dedup as spam prevention requirements
- NAT traversal: added TURN server guidance for same-WiFi and
restrictive network fallback (~20% of cases)
- Audio routing: documented MODE_IN_COMMUNICATION, earpiece/
speaker/Bluetooth SCO cycling, ringback tone, ringtone
- Platform integration: foreground service (microphone type),
proximity wake lock, PiP mode, runtime permissions
- Error handling: SDP creation failures, ICE_CONNECTION_FAILED,
session creation errors
- JSON escaping: noted that ICE candidate SDP strings MUST be
properly escaped in the content JSON
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
All GiftWrapEvent.create() calls in WebRtcCallFactory now pass
expirationDelta=20 so relays can garbage-collect the wraps after
the signaling data is no longer relevant. The actual expiration
timestamp is createdAt + 20s + 2 days (to account for the
randomized createdAt in NIP-59 gift wraps).
Previously only the inner events had expiration tags — the outer
gift wraps persisted indefinitely on relays.

- Add case-insensitive role matching in ParticipantTag (accepts both
"host" and "Host" from other clients per NIP-53 spec)
- Add PARTICIPANT role to ROLE enum per NIP-53 spec
- Add MeetingSpaceEvent (30312), MeetingRoomEvent (30313), and
MeetingRoomPresenceEvent (10312) consumption in LocalCache
- Create rendering composables for MeetingSpaceEvent and MeetingRoomEvent
with status flags (OPEN/PRIVATE/CLOSED for spaces, LIVE/PLANNED/ENDED
for rooms) and participant display
- Add meeting kinds to all discovery feed relay filters (global, authors,
hashtag, geohash, community)
- Add meeting kinds to ChannelCardCompose and LiveActivityCard thumb
rendering
- Add meeting kinds to KindRegistry search aliases

#3 JSON escaping: CallIceCandidateEvent.serializeCandidate() now
escapes backslashes and quotes in SDP/sdpMid strings before
interpolation. Prevents malformed JSON when SDP contains special
characters.
#4 Thread safety: remoteDescriptionSet changed from Boolean to
AtomicBoolean to prevent race conditions between WebRTC callback
threads and main thread accessing the flag simultaneously.
#5 Async cleanup: hangup() no longer calls cleanup() synchronously
after launching the coroutine. Cleanup is now triggered by the
CallManager state collector when Ended state is reached, avoiding
resource disposal during active WebRTC callbacks.
#7 EglBase leak: createWebRtcSession() now wraps initialize() and
createPeerConnection() in try-catch that disposes the session on
failure, preventing EGL context leaks from failed initialization.
#10 SDP failure: createOffer/createAnswer onCreateFailure() now
calls onError() to surface SDP creation failures to the user
instead of silently logging them.
#11 Notification age: EventNotificationConsumer now uses
CallOfferEvent.EXPIRATION_SECONDS (20s) instead of hardcoded 30s
to align with the actual event expiration.

1. Move UI toggle state out of CallState.Connected:
- Removed isAudioMuted/isVideoEnabled/isSpeakerOn from domain
CallState. These are UI concerns, not call state.
- Added StateFlows for toggles in CallController (isAudioMuted,
isVideoEnabled, isSpeakerOn) with proper toggle methods.
- CallScreen reads toggle state from CallController flows.
- Removed toggleAudioMute/toggleVideo/toggleSpeaker from
CallManager (no longer manages UI state).
2. Move ICE candidate parsing to quartz layer:
- Added candidateSdp(), sdpMid(), sdpMLineIndex() parsers and
serializeCandidate() to CallIceCandidateEvent in quartz.
- Removed companion object with parseIceCandidate/
serializeIceCandidate from CallController.
- CallController now uses quartz-layer parsing directly.
- Updated IceCandidateSerializationTest accordingly.
3. Add helper methods to CallManager:
- currentCallId() and currentPeerPubKey() extract from any
active state, reducing repeated when expressions.
4. Fix empty callId bug in ChatroomScreen:
- Navigation to ActiveCall now uses callManager.currentCallId()
instead of hardcoded empty string.
https://claude.ai/code/session_017hZm7yu7CzmcQgZGSaqSXS
- Change EXPIRATION_SECONDS from 300 to 20 for all call signaling
events (offer, answer, ICE, hangup, reject, renegotiate)
- Change MAX_EVENT_AGE_SECONDS from 30 to 20 to match
- Update NIP-AC doc accordingly
- Fix SecurityException crash on SDK 36: phoneCall foreground service
type requires MANAGE_OWN_CALLS permission. Switch to microphone
type which only needs RECORD_AUDIO (already granted).

Rename the existing BookmarkListEvent (kind 30001) to OldBookmarkListEvent
and create a new BookmarkListEvent with kind 10003 as per the updated spec.
- OldBookmarkListEvent (kind 30001): Kept as-is for backward compatibility,
displayed as "Old Bookmarks" in the Bookmark Lists screen
- BookmarkListEvent (kind 10003): New replaceable event, all new bookmark
operations (save/check/remove) use this kind
- Both kinds are displayed as separate items in the Bookmark Lists screen
- Old Bookmarks screen includes a "Move All to New Bookmarks" button that
migrates public bookmarks to public and private to private
- Created PrivateReplaceableTagArrayEvent base class for replaceable events
with encrypted private tags (kind 10003 is in the 10000-19999 range)
- Updated all relay filters, search queries, and profile views to fetch
both kinds
- Updated Android and Desktop modules

DescriptionTag, ThumbTag supporting dimensions per spec
- award/ - BadgeAwardEvent (kind 8) with build() method
- profiles/ - BadgeProfilesEvent (kind 30008) with AcceptedBadge tag
for proper paired a+e tag parsing per NIP-58 spec
Adds build() companion methods to all three event types and full
spec compliance including image/thumb dimension support.
