CatalogNode<Self, ROut>A Node with typed catalog ROut (union of resource handles). Prefer
import type for those handles (C4). Use with listen / clients.
Catalog members must be structurally distinct types (different specs / service shapes) —
identical Tag shapes collapse in TypeScript, so Jobs | Emails cannot prove C3.

A

with typed catalog ROut (union of resource handles). Prefer
import type for those handles (C4). Use with
listen

.

The Context key of a
Node
(HSelf = its identity): a service whose value is the
transport
NodeProtocol
. Stored on a node-bearing tag under
nodeSym
; read by
Hyperlink.client
to resolve where to connect (its requirement channel).

The transport a
Node
speaks — tag-style names (apps rarely type this alias; they write
the literals or get inference from url / path):
"Http" — RpcClient.layerProtocolHttp (servers / CLIs)"WebSocket" — browser WS (layerProtocolWebsocket / client layerProtocolSocket over WS)"IpcSocket" — Unix-domain socket (same-machine; see
ipcServer
)
Stamped on the node so the topology is self-describing about how to reach it — connect/client
derive the transport from it. Inferred from a ws(s):// url, an http target, or { path } →
IpcSocket; otherwise declare it explicitly.
