Post-implementation spec sync after the call-completion batch landed (commits e4a2594..a3825f5). The sub-agent review flagged no spec drift, but comparing the implemented types against the spec sketches surfaced five details the specs didn't name — filled in here so the spec matches what was built: - client-and-adapters.md: name the shared Dispatcher (protocol/dispatch.rs) + RemoteFilter mechanism that enforces ADR-028's default-deny at dispatch time (the load-bearing security gate — checks remote_safe before building context, before any capability material reaches the handler). Add ClientError/RemoteIdentity types, the spawn_dispatch lower-level API, and the services_list_handler_peer_scoped wiring (the assembly layer must register the peer-scoped services/list handler for a CallClient's registry, not the plain one). Record the v1 TLS client-auth gap (AcceptAnyServerCertVerifier, with_no_client_auth) as OQ-29. - call-protocol.md: point the adapter dispatch-loop description at the shared Dispatcher (dispatch.rs) so readers find the mechanism ADR-017 §1 commits to. - open-questions.md: OQ-29 — CallClient TLS client-auth + remote-identity verification is a two-way-door remainder; the no-env-vars invariant is unaffected (auth_token flows via call-protocol payload, not TLS). - READMEs: current-state now reflects completion done + reviewed (207 lib + 2 integration tests); OQ-29 added to both OQ summaries.
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 The previous implementation has been archived and a greenfield rebuild is in progress.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.
