Adds docs/research/alknet-channels/poc-plan.md — a standalone three-step POC plan that derisks the channels layer in isolation (no call protocol, no real transport, no real adapters): - Step 1: chunk format + N-channel demux/mux — generalizes TTY's 5-byte ChunkReader/ChunkWriter to the 9-byte format, validates decompose→stream→ recompose for 3+ concurrent channels with the sync-core/async-shell split pattern from TTY's REQ-TTY-01. - Step 2: per-channel Connection presentation — wraps each reassembled channel as Connection::from_stream and runs a minimal echo ProtocolHandler through the full path. Validates the existing Connection abstraction is sufficient; no core changes needed for the POC. - Step 3: tunnel handler — opens a TcpStream and pumps bidirectionally, reusing TTY's pump_session shape with two pumps. Validates the same concepts behind the TTY crate work as a generic port proxy. Stretch goals: WASM build of the sync core, mixed channel types on one connection, hub relay sketch with channel_id remapping. Adds three open questions to phase-0-findings.md: - OQ-CH-12: unknown channel_id on demux (lenient drop vs strict error). - OQ-CH-13: core BidiStreamSource trait — additive refactor to make ChannelConnection a first-class peer of QUIC (many bidi streams) rather than a bag of yield-once Connections. Likely +EV; not needed for the POC but should be evaluated in Phase 1. - OQ-CH-14: client-side channels endpoint — the symmetric ChannelClient type (analogue of AlknetEndpoint vs CallClient). After the POC we're probably going to need some light refactoring to the core to make these easier; mostly additive and not breaking in major/pita ways. Updates phase-0-findings.md De-risk POC section to point at the detailed plan and adds the poc-plan to References.
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 The previous implementation has been archived and a greenfield rebuild is in progress.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.
