A group's roster changed silently. An add merges on the steward's commit-inactivity timer, and the members that receive its commit apply it, but neither surfaced any observation: Core::wakeup returned () and the client worker discarded it, and GroupV2Convo mapped only chat messages into a ConvoOutcome, so a commit produced an empty outcome. An app could learn a group grew only by re-selecting the conversation, a manual refresh, or a later message from the new member.
de-mls already reports the change: CommitApplied (adds and removes) and WelcomeReady (adds) both fire, on every member, when a commit merges. Drain them into the observation and emit a new event.
- ConvoOutcome gains members_changed, set by GroupV2Convo when a poll cycle's drained de-mls events include CommitApplied or WelcomeReady. It rides alongside content, the same way a protocol-only frame already yields content: None.
- Convo::wakeup returns a ConvoOutcome instead of (), mirroring handle_frame, so the steward's own timer-driven commit is observable. Kinds with no timers return ConvoOutcome::empty; Core::wakeup and the worker translate it through the same events_from_inbound path inbound payloads use.
- New Event::ConversationMembersChanged { convo_id }: the app re-fetches group_members. Fires on every member a commit reaches, so the inviter sees its own add land and existing members see later joins.
libchat
Supporting library for Logos-chat
Example app
bin/chat-cli is an end-to-end encrypted CLI chat app
built on this library. By default it uses logos-delivery
(Waku-based) as the transport so two users anywhere in the world can chat by
sharing an intro bundle. A local file transport is also bundled in; pick at
runtime with --transport <logos-delivery|file>.
# Build logos-delivery with Nix
nix build .#logos-delivery
# Build chat-cli with Cargo
LOGOS_DELIVERY_LIB_DIR=./result/lib cargo build --release -p chat-cli
# Run binary (defaults to --transport logos-delivery)
./target/release/chat-cli --name alice
See bin/chat-cli/README.md for full build,
run, and test instructions.
