# 152. The operator's surface is a module the mesh assigns: the console
|
||||
|
||||
## Context
|
||||
|
||||
**Since the bus moved, nobody can ask the mesh anything without opening a shell on a machine.** Every
|
||||
tool call an operator's assistant makes fails, on every machine including the one the operator sits
|
||||
at, with *AMQP not connected*
|
||||
([issue 147](../04-ISSUES/147-the-operators-tools-still-dial-the-bus-that-was-removed/00-report.md)).
|
||||
The program answering is the predecessor's tool server, started on the workstation by hand, with the
|
||||
predecessor's broker address written into the assistant's own configuration. It has no manifest, no
|
||||
assignment, no account on the bus, and the mesh has never known it exists. Nothing regressed: the
|
||||
mesh removed a transport that a program outside the mesh still dials.
|
||||
|
||||
**The mesh has a tool model, and it works.** A module serves each tool on its own subject and its
|
||||
account may serve nothing else ([ADR 0047](0047-a-module-runs-its-code-as-its-own-process-with-its-own-account.md));
|
||||
a person is issued an account whose only permission is to publish the tool subjects named at issue
|
||||
([25 — The bus on NATS](../03-DESIGN/01-to-be/25-the-bus-on-nats.md) §7); a client on the
|
||||
runtime repository's main branch speaks that account as a command line and as an MCP server. Measured
|
||||
on the live mesh on 2026-09-28: a call to the forge's `gitea_list_repos` answered with real
|
||||
repositories; the tool list came back empty, because it asks the catalogue for a tool nothing serves
|
||||
([ADR 0132](0132-a-seat-carries-the-tools-its-holder-must-serve.md)).
|
||||
|
||||
**Two records have already said where the surface belongs.** ADR 0132's consequences: *the MCP
|
||||
surface belongs inside the mesh — a module the mesh assigns to the machine where the agent sits, with
|
||||
a credential the mesh minted and authority derived from what it may call, not a program started by
|
||||
hand with a credential printed to a terminal.* Design [33](../03-DESIGN/01-to-be/33-the-tools-the-mesh-answers.md)
|
||||
§6 says the same. Neither is a decision about the surface: 0132 decided where a seat's tools live,
|
||||
and named the surface in passing.
|
||||
|
||||
**And one record says the opposite, in the letter.** [ADR 0095](0095-the-control-plane-is-the-way-to-ask-a-module.md)
|
||||
made the control plane *the* way to ask a module, deferred "calling is a grant" until something asked
|
||||
for it, and recorded that *nothing outside the control plane can*. A person's account (design 25 §7,
|
||||
built 2026-09-28) is exactly that grant, minted for a person. So 0095's exclusivity has already been
|
||||
widened once without a record saying so; a module that calls tools widens it a second time, and this
|
||||
record is where that is said.
|
||||
|
||||
**What a module's account may do today, counted from the composition** (`internal/broker`): publish
|
||||
its own events, publish the accept subjects of seats it uses, subscribe its own tools and what it
|
||||
consumes. No module principal may publish another module's tool subject. Of 72 modules in the
|
||||
catalogue, 45 serve tools and 0 may call one.
|
||||
|
||||
The question the work order asks before any code: **does the mesh grow its own operator surface, or is
|
||||
the surface an ordinary module that happens to serve tools?**
|
||||
|
||||
## Considered Options
|
||||
|
||||
**1. The control plane serves the agent protocol itself** — a listener on the controller, or a verb
|
||||
its binary runs. Rejected. It puts a surface for tools the control plane does not implement on the one
|
||||
component that must stay answerable while it is itself being replaced, which is the reason 0132
|
||||
rejected the control plane as the answer to discovery. A person on a workstation would reach it over
|
||||
the network, and the networked surface [ADR 0035](0035-one-implementation-several-surfaces.md)
|
||||
reserves for that authenticates through an OAuth2 provider that is not configured — so the controller's
|
||||
`api` verb correctly serves nothing today, and this option would either wait for it or bypass it.
|
||||
|
||||
**2. A program a person installs and starts by hand with a printed credential** — what exists on the
|
||||
runtime repository's main. Rejected as the end state. It is outside the mesh in every way issue 147
|
||||
names: no assignment, no declaration, no seat, no check that it reaches anything, revoked only by a
|
||||
person remembering to. It is the predecessor's arrangement one bus later, and it fails the same way
|
||||
the next time an address moves. It stays as the recovery path, the way the command line does
|
||||
(ADR 0035): a credential from `operator issue` and the `mesh` client work with no console assigned.
|
||||
|
||||
**3. An ordinary module, assigned to the machine the person sits at, holding a credential the mesh
|
||||
minted, serving the mesh's tools on that machine's loopback.** Chosen.
|
||||
|
||||
## Decision
|
||||
|
||||
**The console is a module.** `mesh-console` is built by the mesh, registered like any module,
|
||||
assigned to a machine, and given a bus credential sealed to that machine. It serves the mesh's tools to
|
||||
whoever is on that machine: to an agent over MCP, and to a person through the same endpoint. Assigning
|
||||
it to a machine is what makes the mesh reachable from there; unassigning it revokes that, at the next
|
||||
composition, with nothing on the machine to remember to remove.
|
||||
|
||||
**A grant to call is a manifest word: `invokes`.** A module declares the tools it calls, each as
|
||||
`<module>.<tool>`, or the single entry `*` for every tool on the mesh. The bus grants exactly that
|
||||
publish side and nothing beside it — no event, no subscription, no seat. This is ADR 0095's deferred
|
||||
first option, taken now that a consumer asks for it; a person's account already has this shape, and
|
||||
the same composition derives both. The control plane's `ask` stands, and 0095's audit point with it:
|
||||
every call still passes one account whose permission list says what it may ask.
|
||||
|
||||
**Authority is the machine's login.** The console listens on the machine's loopback only, declared
|
||||
`from: machine`, so whoever can open a socket on the machine is whoever owns the machine, and *the
|
||||
account that installed the host owns the mesh on that node*
|
||||
([ADR 0034](0034-the-local-account-owns-the-mesh.md)). Anything on a machine may call anything on it,
|
||||
and that is the whole of local ([ADR 0144](0144-anything-on-a-machine-may-call-anything-on-it.md)).
|
||||
The mesh knows no person: what the audit sees is which console asked, under the account
|
||||
`<node>.mesh-console`. How a person's identity reaches a session is the question design 15 leaves
|
||||
open, and this record does not close it.
|
||||
|
||||
**What the console lists is asked of the modules.** Design 33 §5: a module's own tools are answered by
|
||||
the module, from the code that defines them. The tool runtime therefore answers one reserved verb for
|
||||
every module it serves — `tools`, the module's tool names, descriptions and argument schemas — and the
|
||||
console assembles its list by asking the catalogue which modules the mesh holds and each module what
|
||||
it answers. A module that is not running is absent from the list and says so; a tool an agent already
|
||||
knows the name of can be called whether or not it was listed. A module may not name a tool of its own
|
||||
`tools`; the runtime refuses the collision at load rather than letting one shadow the other. A
|
||||
role's tools, and the mesh's own verbs, join the list when the `mesh-controller` seat serves them
|
||||
(design 33 §1, third family) — the console reads whatever the mesh can say about itself, and grows as
|
||||
that does.
|
||||
|
||||
**The console holds one credential and one grant: `*`.** It is the operator's surface on a machine the
|
||||
operator owns; narrowing what it may call is a setting on its assignment, which
|
||||
[ADR 0046](0046-a-module-configuration-is-its-assignments-not-its-manifest.md) already provides for
|
||||
and nothing here builds.
|
||||
|
||||
## Consequences
|
||||
|
||||
- **The way a person drives the mesh is inside the mesh.** It is declared, delivered, replaced and
|
||||
revoked by the same machinery as everything else, and `status` says whether the machine carrying it
|
||||
has applied. Issue 147's shape — a surface kept alive by an address in a file — cannot recur, because
|
||||
there is no file: the console's credential names the bus the mesh is on, and moves when it does.
|
||||
- **A module may now call tools, which ADR 0095 had reserved to the control plane.** The grant is
|
||||
explicit, per tool or `*`, and derived by the same composition that grants everything else. A module
|
||||
that declares no `invokes` gains nothing. What got harder: a manifest reviewer has one more field to
|
||||
read for authority, and `*` in it deserves the reader's attention every time.
|
||||
- **A new manifest word ships one release before any manifest uses it**, and must reach both parsers:
|
||||
the build machine's and the running controller's. The console's manifest cannot be registered until
|
||||
the controller and the builder that packages it have been rebuilt with the word.
|
||||
- **Discovery costs a fan-out per list.** One request per module the mesh holds, answered at once by
|
||||
the bus for every module nothing serves, so the cost is bounded by the modules that are up. The list
|
||||
is cached briefly in the console; a module assigned a moment ago appears at the next refresh.
|
||||
- **Every tool runtime must be rebuilt once** to answer `tools`. Until a module is, it is callable and
|
||||
not listed, and the console says which modules did not answer.
|
||||
- **The mesh's own verbs are not in the console yet.** `status`, `push`, `assign` are the
|
||||
`mesh-controller` seat's tools under 0132, and the three prerequisites 0132 names are still not in
|
||||
place. A person asking what a node runs still opens a shell for that question, and that gap is design
|
||||
33's to close, not this record's — recorded here so nobody reads the console as the whole of 147.
|
||||
- **The person's credential is not retired.** `operator issue` and the `mesh` client remain the path
|
||||
when no console is assigned, and the path an operator uses to bring a mesh up far enough to assign
|
||||
one.
|
||||
|
||||
## How this is checked
|
||||
|
||||
| Rule | Checked by |
|
||||
|---|---|
|
||||
| A module's `invokes` becomes exactly that publish grant, and nothing else | the bus user composition test: a module invoking `shop.price` may publish that subject and no other tool's; `*` may publish every tool subject; neither may publish an event or subscribe anything it did not consume |
|
||||
| A malformed `invokes` entry is refused at registration | a parser test: an entry naming no tool is a problem named in the manifest's words |
|
||||
| The runtime answers `tools` for every module it serves | the runtime's test: a module registering two tools answers three names, and a module naming one of its own `tools` is refused at load |
|
||||
| The console's list is what the modules answer | the client's test against a real bus: two modules up, a third the catalogue holds and nothing serves, and the list carries the two and names the third as not answering |
|
||||
| A call from the console reaches a module over the bus | the same test, and the live mesh: the console assigned to a workstation answers `tools/list` on its loopback and a call to the forge returns repositories |
|
||||
| The console listens on loopback and nowhere else | its manifest declares `from: machine`, and the filter composed for the machine opens nothing for it |

# The console, as it runs
|
||||
|
||||
**The mesh's tools reach a person through a module the mesh assigned to their machine.** Since
|
||||
2026-09-30 a workstation that is a node can be assigned `mesh-console`; the mesh mints a bus account
|
||||
`<node>.mesh-console`, seals its credential to the machine, and the container binds
|
||||
`127.0.0.1:<port>` with the port the mesh assigned for the manifest's declared one. An agent on the
|
||||
machine is pointed at `http://127.0.0.1:<port>/mcp` and sees the mesh's tools; a person uses the same
|
||||
endpoint. Nothing on the machine holds a credential a person had to carry.
|
||||
|
||||
## What it answers
|
||||
|
||||
`initialize`, `tools/list`, `tools/call`, over HTTP, one JSON body per request, no session and no event
|
||||
stream. `tools/list` is what the running modules answered: every tool runtime built on or after that day
|
||||
serves a `tools` verb for its module, and the console asks the catalogue for the roster and each module
|
||||
for its tools. A module that did not answer is named in the list's `_meta.notAnswering`. On the day it
|
||||
shipped that was 36 of 51 modules — those that serve no tools at all, and those whose rebuilt runtime the
|
||||
mesh records rather than rolls out — and 62 tools from the rest.
|
||||
|
||||
`tools/call` reaches any tool by `<module>.<tool>`, listed or not. The console's grant is `*`, so what it
|
||||
may call is every tool on the mesh; its account may publish nothing else and subscribes nothing.
|
||||
|
||||
## What it does not answer
|
||||
|
||||
The mesh's own verbs. `status`, `push`, `assign` and the rest are not served on the bus — they are the
|
||||
`mesh-controller` seat's tools under ADR 0132, whose three prerequisites are not built — so a person
|
||||
still opens a shell on the control node for them. The console's handshake says so.
|
||||
|
||||
## Around it
|
||||
|
||||
- **`invokes`** in a manifest is the grant. It is composed into the bus's user list exactly as a
|
||||
person's account is; the console is the only module that declares it.
|
||||
- **`module check <file|dir>…`** on the controller's binary judges a manifest with no mesh: the strict
|
||||
parse, every per-manifest problem, and the rules between the manifests given. It prints what it cannot
|
||||
judge without a store rather than refusing. The console's own manifest was the first thing checked
|
||||
with it, and the whole catalogue passes.
|
||||
- **The person's client remains.** `operator issue` and `mesh tools|call|mcp` with a credential file
|
||||
still work, for a machine that is not a node and for a mesh not yet able to assign anything.
|
||||
`mesh tools --console <url>` goes through a running console with no credential; it is covered by the
|
||||
runtime repository's tests and was not exercised on the live mesh.
|
||||
|
||||
## What shipped bent
|
||||
|
||||
- A module registered by hand from the catalogue with `--source <url> --path modules/<m>` records a URL,
|
||||
not a place on the git seat: `--self` takes the forge path form (`<owner>/<repository>`), which the
|
||||
operator did not pass. The rebuild-on-merge matched the URL anyway.
|
||||
- Modules whose upgrade policy is *record* — the forge among them — answered `tools` only once
|
||||
something pushed their rebuilt runtime; until then they are listed as not answering while still
|
||||
callable. That is the policy doing what it says, not a fault of the console.

# 34 — The console
|
||||
|
||||
**The mesh's tools, on the machine a person sits at, served by a module the mesh assigned there.**
|
||||
An agent reaches them over MCP on the machine's loopback; a person reaches the same endpoint. Nothing is
|
||||
installed by hand, nothing is configured with an address, and the mesh knows the surface exists because
|
||||
it put it there ([ADR 0152](../../02-DECISIONS/0152-the-operators-surface-is-a-module-the-console.md)).
|
||||
|
||||
## 1. What it is
|
||||
|
||||
A module, `mesh-console`, in the catalogue. Its image is the tool runtime's own — the client that
|
||||
already speaks the bus as a command line and as an MCP server — started in a mode that reads the
|
||||
module's credential and listens on loopback. It has no state, no provision, no seat. What it needs is
|
||||
the bus, which it gets the way every module does: a credential the mesh minted for `<node>.mesh-console`,
|
||||
sealed to the machine, delivered as the module's own secret.
|
||||
|
||||
Its manifest says three things nothing else in the catalogue says together:
|
||||
|
||||
- `invokes: ["*"]` — it calls every tool on the mesh, and the bus grants exactly that publish side;
|
||||
- `listens` on a port `from: machine` — the filter opens nothing for it, because loopback is not outside;
|
||||
- no `emits`, no `consumes`, no `tools` — it answers nothing on the bus and nobody can address it there.
|
||||
|
||||
## 2. What it serves, and to whom
|
||||
|
||||
**One endpoint, `POST /mcp` on the machine's loopback**, speaking MCP over HTTP: `initialize`,
|
||||
`tools/list`, `tools/call`. An agent on the machine is pointed at it once — the address is the machine's
|
||||
own and never changes — and sees every tool the mesh can say it has. A person at a terminal uses the
|
||||
same endpoint through the `mesh` client, or through anything that can make an HTTP request; the client
|
||||
needs no credential, because the console holds it.
|
||||
|
||||
**The endpoint is the machine's login.** It binds `127.0.0.1` and nothing else. Whoever can connect is
|
||||
on the machine, and whoever is on the machine is the account that owns the mesh there
|
||||
([ADR 0034](../../02-DECISIONS/0034-the-local-account-owns-the-mesh.md),
|
||||
[ADR 0144](../../02-DECISIONS/0144-anything-on-a-machine-may-call-anything-on-it.md)). There is no
|
||||
token, no login page and no second identity, on purpose: a credential a person had to carry to reach
|
||||
their own machine's console would be the arrangement this replaces, moved one hop.
|
||||
|
||||
## 3. How it knows what the mesh can do
|
||||
|
||||
Design [33](33-the-tools-the-mesh-answers.md) §5 splits discovery in two: a role's tools are read from
|
||||
the mesh's records, a module's own are asked of the module. The console builds the second half now and
|
||||
reads the first when it exists.
|
||||
|
||||
**Every tool runtime answers `tools`.** The runtime that serves a module's tools also serves one verb of
|
||||
its own under that module's name, `mesh.mod.<module>.tool.tools`, answering the module's tool names,
|
||||
descriptions and argument schemas — the definitions from the code that answers them, and from nowhere
|
||||
else. A module may not name a tool of its own `tools`; the runtime refuses the collision at load.
|
||||
|
||||
**The console asks the catalogue which modules the mesh holds, then asks each.** `catalog_modules`
|
||||
answers the roster; one `tools` request per module, in parallel, answers the list. The bus refuses at
|
||||
once a request nothing serves, so a module that is not running costs nothing and is named in the answer
|
||||
as not answering, rather than silently absent — *silence and success must never look alike*. The list is
|
||||
kept for a short while and refreshed, so an agent asking on every turn does not fan out on every turn.
|
||||
|
||||
**A tool that was not listed can still be called.** Listing is discovery; calling is the grant. An agent
|
||||
that knows a tool's name asks for it by `<module>.<tool>` and the module answers or the bus says why not.
|
||||
|
||||
**What is missing from the list, and until when.** A role's tools and the mesh's own verbs — `status`,
|
||||
`push`, `assign` — are the `mesh-controller` seat's under ADR 0132 and are not served yet; their three
|
||||
prerequisites are listed in that record. When the seat serves them, the console lists them beside the
|
||||
modules' own, and the person stops opening a shell for the mesh's own questions. Until then the console
|
||||
says so in its handshake.
|
||||
|
||||
## 4. Where it runs
|
||||
|
||||
On whichever machines an operator sits at, by assignment. It is not on the control node by default and
|
||||
does not need to be: it reaches the bus like any module, from anywhere in the mesh. A machine that is
|
||||
not a node cannot have it, which is the right refusal — the mesh reaches what it declares, and a
|
||||
workstation that wants the console joins first.
|
||||
|
||||
The person's credential and the `mesh` client (design [25](25-the-bus-on-nats.md) §7) remain the path
|
||||
for a machine that is not a node, and the path to a mesh not yet far enough along to assign anything.
|
||||
|
||||
## 5. Removing it
|
||||
|
||||
Unassigning the console from a machine revokes its bus account at the next composition and stops the
|
||||
container; nothing is left on the machine that could still connect. An agent pointed at the loopback
|
||||
address gets a refused connection, which is the truthful answer.
|
||||
|
||||
## How it is checked
|
||||
|
||||
| Check | Defends |
|
||||
|---|---|
|
||||
| a module invoking one tool may publish that subject and no other tool's; `*` may publish every one; neither may publish an event or subscribe what it did not consume | ADR 0152, the grant |
|
||||
| a module registering two tools answers three names to `tools`, with schemas; a module naming its own `tools` is refused at load | ADR 0152, discovery |
|
||||
| against a real bus: two modules up, a third held and not running — the console lists the two and names the third as not answering | ADR 0152, silence is not success |
|
||||
| a call through the console's endpoint reaches a module over the bus and the answer is the module's own, unshaped | ADR 0035, a surface decides nothing |
|
||||
| on the live mesh: the console assigned to a workstation answers `tools/list` on loopback and a call to the forge returns repositories | the exit of work-order step 3 |
|
||||
| the composed filter for a machine carrying the console opens no port for it | ADR 0144 |
|
||||
|
||||
## What shipped, 2026-09-30
|
||||
|
||||
Everything above, the same day: mesh-controller PR 164 (`invokes`, `module check`), mesh-tools PR 20
|
||||
(`mesh serve`, the `tools` verb), mesh-catalog PR 181 (`mesh-console`). Verified on the live mesh: the
|
||||
console assigned to a workstation answered `tools/list` on its loopback with 62 tools from the modules
|
||||
whose runtimes had been rebuilt to answer `tools`, named 36 modules as not answering (modules that serve
|
||||
no tools, and modules whose new runtime the mesh records rather than rolls out), and a `tools/call` of
|
||||
the forge's `gitea_list_repos` returned repositories. An agent on that machine reaches it as an HTTP
|
||||
MCP server and reports it connected. The mesh assigned the declared port unchanged, which is what a
|
||||
machine with nothing else on it does; the console binds whatever it is given.
|
||||
|
||||
Two things shipped bent, both stated in [`00-as-is/13-the-console.md`](../00-as-is/13-the-console.md):
|
||||
the person's client through the console (`--console`) exists and was exercised in the test suite, not
|
||||
on the live mesh; and a module registered from the catalogue by hand recorded its source as a URL rather
|
||||
than as a path on the git seat, because `--self` takes the forge path form — the rebuild-on-merge still
|
||||
matched it by URL.
|
||||
|
||||
## What this does not settle
|
||||
|
||||
- Narrowing a console's grant per assignment. ADR 0046 makes it a setting; nothing reads one yet.
|
||||
- The mesh's own verbs on the bus. Design 33's third family; this document only says where they appear
|
||||
once they exist.
|
||||
- A person's identity behind the console. The mesh sees the console's account; design 15 keeps the
|
||||
question open.

The work order's question — does the mesh grow its own operator surface, or is the surface an

ordinary module — is answered by [ADR 0152](../../02-DECISIONS/0152-the-operators-surface-is-a-module-the-console.md):
|
||||
**the console is a module.** `mesh-console` is assigned to the machine a person sits at, holds a
|
||||
credential the mesh minted, calls tools under a grant its manifest declares (`invokes`), and serves the
|
||||
mesh's tools on that machine's loopback to an agent over MCP and to a person through the same endpoint.
|
||||
Designed in [34 — The console](../../03-DESIGN/01-to-be/34-the-console.md).
|
||||
|
||||
What that leaves, said plainly so nobody reads this record as closed on the whole of its first
|
||||
paragraph: the console reaches every tool a *module* serves. The mesh's own questions — what a node
|
||||
runs, what is assigned — are the `mesh-controller` seat's tools under ADR 0132 and are not on the bus
|
||||
yet; for those a shell is still the way, and design 33 is where that closes.
|
||||
|
||||
The predecessor's program on the workstation is not replaced by the mesh; it is left where it is and
|
||||
the assistant is pointed at the console beside it. The `hal` entry in the assistant's configuration
|
||||
still names things that are not the mesh's.
|
||||
|
||||
**Verified live, 2026-09-30 evening.** The four pull requests merged; the console was registered

(checked first with `module check`), built, assigned to a workstation, issued a bus account, and pushed.

is. As-is: [`13-the-console.md`](../../03-DESIGN/00-as-is/13-the-console.md).
