mesh/merge-gate pass: builds mesh-sdk, sent nowhere; no bus step; every machine composes with the change as it did without (4 of 4 compose)
mesh/repo-check pass: its merge-check.sh passed, each part in its toolchain: merge-check.sh (typescript), go/merge-check.sh (go)
mesh/delivery delivered
mesh/delivery-group group fix/365-a-tool-call-names-its-caller delivered: every member is delivered
go: a tool reads its caller from the runtime, so a record can say who acted (hq issue 365)
The runtime names the caller it took from the subject a call arrived on in the
call's _meta; stdio.CallerOf(args) hands it to the tool. Never read from the
arguments, and Unproven when the runtime named none, so a bundle on an older
runtime still says, explicitly, that its caller was not proven.

# mesh-sdk for Go
`stdio.Serve("", tools)` speaks MCP over stdio to the node's tool runtime, as the module the runtime
names (novox/hq ADR 0188, ADR 0193). A `Tool` is a name, a description, an argument schema and a
function; calls run concurrently. `stdio.CallerOf(args)` inside a tool is who called it: the bus user the runtime took from the subject the call arrived on, named in the call's `_meta`, never read from the arguments — or `stdio.Unproven` when the runtime named none (novox/hq issue 365). A tool named `<seat>.<verb>` is the seat's implementation.
`stdio.Emit(type, body)` publishes an event as the module, `stdio.Subscribe(pattern, handler)` receives the module's events (taken when the handler returns nil, offered again when it returns an error — the one rule is in the repository README, "Taking an event") and `stdio.Ask(key, body)` calls a tool, and `stdio.State(name)` gets, puts, deletes, lists and watches the module's declared state — all through the runtime (novox/hq ADR 0193, 0198, 0201). Standard library only.
## Installing
```
GOPRIVATE=git.novox.be go get git.novox.be/novox/mesh-sdk/go@latest
```
Releases are tagged `go/vX.Y.Z` in this repository, the subdirectory form Go's module system expects,
at the same version as the TypeScript package.
What it holds, under ADR 0039's test: the stdio loop and the tool type, and `cli`, the local protocol
`mesh-cli` speaks to the node-engine on its machine (novox/hq ADR 0272): the socket's path and one request and one
answer. Nothing else — no bus, no client, nothing of any module's. `go build ./example` and pipe a `tools/list` request into it.
