The operator's direction, absent from every record until now: the SDK must not limit who writes a
module; tools and services may be written in any language; one module may ship several bundles
(tools, a seat's implementation, a daemon); skeleton first, a full implementation when the work
requires it. ADR 0175 had the runtime import a bundle, which only JavaScript can be.
0187 makes a tools bundle a process the node's runtime launches and speaks MCP over stdio to —
the vocabulary the runtime already speaks outward — so any language with an MCP library can write
one today and the mesh's SDK per language is thin; the transport stays in the runtime (0039's
refusal, kept). Importing a TypeScript bundle is the shortcut, not the contract. Notes in 0175,
0039 and 0150 say where their mechanism moved; design 38 records WP1 as built and adds WP1b (the
launcher and the skeleton SDKs); the glossary's bundle widens.
The runtime work of design 37 broken down the way design 28 broke down the
bus: what exists measured (the host needs no change — a process and an
archive are what the runtime and a bundle are; the runtime does the job for
one module and must do it for a list), the order the dependencies allow, and
eight packages each ending at a proof on the live mesh — the lab skipped by
the operator's decision, ADR 0149 cited. WP1 the runtime serves many modules;
WP2 the controller composes one per node (a node principal, bundle archives,
the runtime's process, the gate); WP3 the runtime is a module and the console
its serving mode; WP4 the packet filter moves first; WP5 the shell on a
server; WP6 the service manager on a workstation; WP7–8 named and not broken
down.
Main carried two records numbered 0175 and cycle.py refused it: the one that
landed last (the found front end is uninstalled) takes 0180, the next free
across main and the open changes, with a dated note; design 08's citation
follows it; the index is regenerated.
