OQ-64 and OQ-55 were linked in a circular dependency: the client-side TLS config was deferred behind the dial seam (OQ-55), but the dial needs the TLS config. No second transport can dial until it has a TLS config; the TLS config was deferred until a second transport dials. Schrödinger's code — required and not required until observed. ADR-087 breaks the circle by separating two concerns that were conflated as 'the same seam': 1. TlsClientConfig — rustls::ClientConfig + ADR-034 verifier selection + ADR-084 crypto provider. Transport-agnostic. All decisions made. Buildable today. A PREREQUISITE for any dial, not a consequence of it. 2. The dial (AlknetClient::dial()) — transport-specific connection establishment. Extracting a transport-polymorphic dial from one shape (QUIC) would bake QUIC in. Legitimate deferral (OQ-55, unchanged). The hub makes this non-optional: a hub dials out to workers it supervises and to other hubs (hub-as-client). The first hub deployment (web + native) dials workers over QUIC with the worker's fingerprint pinned. There is no 'later' for the TLS config — it is on the critical path for the first hub and for alknet-worker. Changes: - ADR-087: TlsClientConfig in alknet-tls, not blocked on OQ-55 - OQ-64: resolved (yes, alknet-tls provides TlsClientConfig) - OQ-55: amended — only the dial seam is deferred; TLS client config is explicitly NOT part of the deferral - TLS README: 'Server-only (for now)' section replaced with TlsClientConfig section; crate is no longer server-only - Hub README: dial/supervision section references TlsClientConfig for outbound connections
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 The previous implementation has been archived and a greenfield rebuild is in progress.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.
