Subscription ops discovered via services/list + services/schema now register a StreamingHandler (HandlerKind::Stream) that calls CallConnection::subscribe_with_payload and forwards the remote stream end-to-end (ADR-049 §8). Query/Mutation ops keep the existing make_forwarding_handler (HandlerKind::Once). - Add CallConnection::subscribe_with_payload(payload) mirroring call_with_payload so the forwarding handler can populate forwarded_for (ADR-032) + auth_token on the subscription payload. subscribe() now delegates to subscribe_with_payload. - Add make_streaming_forwarding_handler() in from_call.rs using make_streaming_handler + futures::stream::once(...).flatten() to await subscribe_with_payload then forward its stream. - Branch build_bundles on spec.op_type (already parsed by rebuild_spec_for). - Reuse build_forwarded_payload — no new payload-construction code. - composition_authority: None, scoped_env: None for FromCall streaming leaves (same as Query/Mutation FromCall leaves). - Abort cascade (ADR-016 §6) already wired via PendingRequestMap in subscribe_with_payload. Closes the gap where a from_call-imported Subscription truncated to the first value.
Alknet
Status: Pre-alpha — This project is undergoing a major architectural pivot to an ALPN-as-service model. The previous implementation has been archived and a greenfield rebuild is in progress.
A self-hostable networking toolkit built on QUIC+TLS with ALPN-based protocol dispatch. Each protocol handler (SSH, SFTP, Git, HTTP, DNS, messaging, call protocol) registers an ALPN string on a shared endpoint. The ALPN negotiation during the TLS/QUIC handshake routes connections to the correct handler before any application bytes are read.
Core Insight
A service IS an ALPN. One endpoint, one port, many protocols — dispatched by the TLS handshake, not by application-level peeking or separate listeners.
