The #1 gap in alknet-call: the outbound connection opener. Every downstream consumer (runner, container service, bilateral exchange, NAPI, agent cross-node dispatch) is blocked on it. Shared dispatch loop (ADR-017 §1 — the architectural commitment that keeps CallClient from becoming a parallel protocol implementation): - Extracts the accept-path dispatch (sweeper, accept_bi loop, handle_stream, dispatch_requested, build_root_context, compose_root_env, fail_all on close) out of CallAdapter into a new protocol/dispatch.rs Dispatcher struct. Both CallAdapter::handle and CallClient::connect produce a CallConnection and hand it to Dispatcher::run_loop — the loop is genuinely shared (refactored, not duplicated). - CallAdapter keeps its public API and test-facing wrappers (pub(crate), #[cfg(test)]-gated) that delegate to the Dispatcher. Peer-scoped default-deny (ADR-028 — the one-way-door security dimension): - RemoteFilter { trusted_peer: bool } on the Dispatcher. In default-deny mode (CallClient::new), an incoming call to an op with remote_safe: false returns NOT_FOUND *before* any capability material reaches the handler — a remote peer's call must not populate OperationContext.capabilities from the local registration bundle unless the op is explicitly remote-safe (ADR-028 Context). Trusted-peer mode (CallClient::trusted_peer, explicit opt-in) bypasses the filter. - The accept path (CallAdapter) uses RemoteFilter::trusted() by convention: a direct QUIC client is not a filtered CallClient peer in the ADR-028 sense. - OperationRegistry::list_operations_peer_scoped(trusted_peer) + services_list_handler_peer_scoped for the CallClient's services/list serving path (ADR-028 Assumption 2: a peer should not see ops it cannot call, so discovery and dispatch filters agree). CallClient (src/client/call_client.rs): - CallClient { registry, identity_provider, trusted_peer: bool }. - new() default-deny; trusted_peer() explicit opt-in (ADR-028 §3). - connect(addr, CallCredentials) dials QUIC on ALPN alknet/call (quinn feature), spawns Dispatcher::run_loop, returns a live CallConnection. - spawn_dispatch(connection) shared path for connect + tests. - CallCredentials { tls_identity, auth_token, remote_identity } — all from Capabilities (ADR-014), never env vars (no-env-vars invariant). v1 connects without client-auth TLS identity (server uses AcceptAnyCertVerifier); RawKey client-auth is a two-way-door remainder. - RemoteIdentity { fingerprint } — concrete shape is a two-way door (OQ-25 remainder); the one-way constraint is it comes from Capabilities. - ClientError { Transport, TlsSetup, ConnectionClosed }. - CallConnection is now Clone (shares the inner Arcs) so connect can hand the caller a live clone while the dispatcher task keeps its clone. Tests (199 lib + 1 integration): - Unit: default-deny NOT_FOUND for non-remote-safe; remote_safe dispatches; trusted-peer dispatches all External; default-deny does NOT populate capabilities (the load-bearing security assertion — verified by a handler that inspects context.capabilities and the fact that the handler is never reached for non-remote-safe ops); remote_safe op populates capabilities; services/list peer-scoped hide/trusted variants; CallClient constructors; CallCredentials builder; Send+Sync. - Integration (tests/two_node_call.rs): real QUIC loopback — CallAdapter server (self-signed cert via rcgen) accepts, CallClient connects, client.call() round-trips to server/echo. Proves the connect path + shared dispatch loop work end-to-end. clippy + fmt + test all green.
