Add ConnectionKind::Stream: a single read/write pair behind a Mutex<Option<...>> that accept_bi yields once (then ConnectionClosed). Add Connection::from_stream(send, recv, alpn, remote_addr) and Connection::from_bidi(stream, alpn, remote_addr) constructors. Rename the stream-level SendStreamKind::Mock / RecvStreamKind::Mock to ::Stream (they were already generic Box<dyn AsyncRead/Write> — the wrong name). Rename from_mock to from_stream. Remove MockConnection trait + ConnectionKind::Mock entirely. Migrate all alknet-call test StubConnections to use from_stream with tokio::io::sink() + tokio::io::empty() (immediate EOF on the read side causes handle_stream to exit cleanly, then accept_bi returns ConnectionClosed and the run_loop exits). The yield-once accept_bi contract: QUIC yields many streams, everything else yields one. Handlers that loop (TtyAdapter) get one iteration per single-stream connection; handlers that call once (HttpAdapter) get the stream directly. Both correct, no branching on transport. This unblocks TCP+TLS listeners, SSH channel dispatch, WebTransport streams, and wasm — all via from_stream, all through the same HandlerRegistry, zero handler code changes. See docs/research/transport-generalization/findings.md for the full trace and the yield-once contract.
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 The previous implementation has been archived and a greenfield rebuild is in progress.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.
