Phase 1 architecture for alknet-channels (multiplexing proxy on alknet/channels). Grounded in the completed de-risk POC (28 tests) and the landed ADR-070 (BidiStreamSource trait + Connection::from_source). ADRs: - 071: 9-byte chunk wire format (generalizes TTY's 5-byte) - 072: channel 0 pre-negotiated as alknet/call (no special control plane) - 073: channel lifecycle operations on the call protocol — channel/open, close, control, resources/subscribe; direction field pinned; subscribe from day one (not poll-for-v1 — StreamingHandler machinery exists) - 074: ChannelBidiStreamSource implements BidiStreamSource (ADR-070); into_sub_streams() typed accessor for TTY; accept_bi() generic path - 075: ChannelsAdapter + ChannelManager; REQ-CH-01..04 wire invariants - 076: bounded-buffer backpressure (1 MiB), 256-channel cap, monotonic IDs - 077: TTY inside channels uses sub-streams, not own wire format; amends ADR-052 scope to direct-connect TTY; channels feature on tty - 078: two-pump shutdown-on-completion contract (handler-level) - 079: hub relay translates channel 0, byte-forwards data channels - 080: ChannelClient (QUIC-only); AlknetClient core extraction deferred (OQ-55) Spec docs: overview, channels-wire, channels-connection, channels-adapter, channel-operations, channel-client. OQ-56 (full windowing) and OQ-57 (two-pump helper extraction) are genuine deferred(scope) deferrals with concrete blocking conditions; the contracts are decided, only the extensions are deferred. Hedging audit converted three research hedges into decisions: resources/subscribe (not poll), server-assigned IDs (not if-zero-RTT), bounded-buffer (not if-HOL-becomes-a-problem).
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 The previous implementation has been archived and a greenfield rebuild is in progress.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.
