Foundational architecture documents following the SDD process: ADRs: - 001: ALPN-based protocol dispatch (one endpoint, ALPN negotiation) - 002: ProtocolHandler trait (replaces StreamInterface/MessageInterface) - 003: Crate decomposition (one crate per handler, core provides shared infra) - 004: Auth as shared core (IdentityProvider, hybrid resolution model) - 005: irpc as call protocol foundation - 006: ALPN string convention and connection model (alknet/ prefix, one ALPN per connection) Docs: - overview.md: crate graph, shared types, ALPN registry, failure modes - README.md: index with doc table, ADR table, lifecycle definitions - open-questions.md: 10 OQs across 7 themes (3 resolved, 7 open) Crate spec stubs for all 11 planned crates (alknet-core through alknet CLI). Key decisions resolved during self-review: - AuthContext resolution is hybrid: endpoint resolves TLS-level auth, handlers resolve protocol-level auth (resolves OQ-02) - ALPN is per-connection not per-stream, corrected ADR-001 (resolves OQ-06) - ALPN naming uses alknet/ prefix without versions (resolves OQ-03) - HandlerError return type on ProtocolHandler trait - alknet/secret removed from ALPN registry until OQ-08 resolved

alknet-http
Status: Planned — This spec has not been written yet.
Purpose
HTTP handler implementing ProtocolHandler on ALPN alknet/http. Provides axum router with auth middleware, REST API, dashboard, and MCP endpoint. Also handles standard HTTP ALPNs (h2, http/1.1) and WebTransport upgrade on h3.
Key Questions
- How does HttpAdapter handle both
alknet/httpand standard ALPNs (h2,http/1.1,h3)? - WebTransport upgrade on
h3— is this a separate handler or integrated into HttpAdapter?
