Critical:
- operation-registry: remove stale duplicate OperationEnv impl that
propagated parent.metadata through composition (violated ADR-014);
collapse to one canonical block with metadata: HashMap::new()
- operation-registry: fix request_id collision — format!("env-{name}")
produced identical IDs across concurrent invocations, corrupting
PendingRequestMap correlation and the abort-cascade tree (ADR-016)
- operation-registry + ADR-015: fix OperationContext.internal visibility —
pub field let handlers mark their own call internal (privilege
escalation per ADR-015); change to pub(crate) with pub fn is_internal
Warnings:
- core-types: add Connection::set_identity/identity (OQ-11) to the
Connection type spec — was specified in auth.md but missing from the
type definition
- operation-registry: add Capabilities: Clone design note — invoke()
clones capabilities through composition; explicit security implication
- call-protocol: add CallAdapter root OperationContext construction
example showing internal: false wire path, complementing
OperationEnv::invoke() internal: true composition path
- overview: remove alknet/agent from ALPN registry — agent is a future
consumer of alknet-call (call-protocol operations), not a separate ALPN
- call-protocol: clarify call.requested payload schema and the
leading-slash convention (wire operationId has slash, registry name
does not)
Suggestions:
- operation-registry: cross-reference ResponseEnvelope definition
- core-types: add StreamError to HandlerError mapping table
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 The previous implementation has been archived and a greenfield rebuild is in progress.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.
