# 151. A route's internal name is composed under the node that serves it
|
||||
|
||||
## Context
|
||||
|
||||
A module that requires a route is given two names from one label: a public one, `<label>.<public
|
||||
domain>`, and an internal one, `<label>.<node>.internal`
|
||||
([ADR 0138](0138-an-assignment-binds-an-endpoint-and-says-how-far-it-reaches.md)). Both were composed
|
||||
from the node the module runs on.
|
||||
|
||||
The two are answered differently. The public name is published into every machine's roster at the
|
||||
address of the node whose proxy serves it ([ADR 0066](0066-public-routing-is-name-agnostic.md)), so
|
||||
it reaches the proxy from anywhere in the mesh. The internal name is answered by every machine's
|
||||
resolver as *anything under a node's name goes to that node*
|
||||
([design 08 §2](../03-DESIGN/01-to-be/08-connectivity.md)) — the node it was composed from, which is
|
||||
the consumer's. Where the proxy runs on another machine, that name sends a client to a machine with
|
||||
nothing listening, while the public name works
|
||||
([issue 139](../04-ISSUES/139-an-internal-route-name-resolves-to-the-consumers-node/00-report.md)).
|
||||
Every route on this mesh today is served beside its module, so it has not been seen; `route` is
|
||||
provided mesh-wide precisely so that stops being true.
|
||||
|
||||
Beside it, the roster gave every routed name a second entry with the mesh's suffix appended —
|
||||
`<name>.<public domain>.internal` — because it composed a full name for every entry as it does for a
|
||||
machine. That name resolved on every machine, was served by nothing, and was refused by the proxy at
|
||||
the handshake; the first three names tried while reproducing an unrelated issue were those, and the
|
||||
evidence pointed at a regression that had not happened
|
||||
([issue 157](../04-ISSUES/157-a-routed-names-internal-alias-is-served-by-nothing/00-report.md)).
|
||||
|
||||
## Considered Options
|
||||
|
||||
**1. Keep the consumer's name and publish it at the serving node's address**, as the public name is.
|
||||
The name stays `<label>.<consumer>.internal` and an exact roster entry overrides the wildcard.
|
||||
Rejected: it makes `<x>.<node>.internal` mean *goes to that node* except when it does not, which is
|
||||
the one rule the resolver design states; it needs an entry per route where the wildcard needed none;
|
||||
and which of an exact entry and a wildcard a resolver answers first is the resolver's business, which
|
||||
the mesh deliberately does not know.
|
||||
|
||||
**2. A proxy on every machine, so the serving node is always the consumer's.** Rejected for this
|
||||
question: it is a different decision about what `route` is — a node-scoped seat with a mesh-wide
|
||||
fallback — and this mesh runs one proxy on the hub today. Whatever is decided there, a route served
|
||||
from another machine must have a name that reaches it.
|
||||
|
||||
**3. Compose the internal name under the node that serves the route.** Chosen.
|
||||
|
||||
## Decision
|
||||
|
||||
**A route's internal name is `<label>.<serving node>.internal` — composed under the node whose proxy
|
||||
answers the route, which is the machine the request arrives at.** The public name is unchanged:
|
||||
`<label>.<public domain>` of the node the module runs on, which is where the operator put it.
|
||||
|
||||
Where the proxy runs beside the module — every route on this mesh today — the two nodes are one and
|
||||
nothing changes. Where it does not, the name says where the request goes, which is what a name under
|
||||
a node's name has always meant.
|
||||
|
||||
**A routed name has no mesh form.** The roster publishes it as itself, once, at the serving node's
|
||||
address. Only a machine has a bare name beside its full one.
|
||||
|
||||
What certifies the internal name is unchanged by this: the proxy that terminates it obtains a
|
||||
certificate from the mesh's authority for the names it is given, and it is given this one.
|
||||
|
||||
Taken on the operator's standing instruction to answer the open design questions in the work order.
|
||||
|
||||
## How this is checked
|
||||
|
||||
- **Composition.** A controller test contributes a route from a module on one node to a proxy offered
|
||||
from another, gathered the way the controller gathers a consumer's contribution for a provider on
|
||||
another machine, and asserts the internal name carries the serving node.
|
||||
- **Publication.** A controller test renders a roster with a machine and a routed name and asserts
|
||||
the routed name appears as itself, once, and never with the suffix appended.
|
||||
- **On the mesh.** After the change no machine's roster carries a `<domain>.internal` entry, and a
|
||||
route's internal name still answers from a container with a certificate from the mesh's authority.
|
||||
|
||||
## Consequences
|
||||
|
||||
- **A route served from another machine now has a usable internal name.** The first module assigned
|
||||
that way will resolve, where before it would have resolved to the wrong machine with no error.
|
||||
- **The internal name of a route can change when its proxy moves.** A route re-homed from one proxy
|
||||
to another gets a new internal name, as the design's rule implies; clients that dialled the old one
|
||||
reach the old machine. The public name does not move with the proxy and is the stable one.
|
||||
- **The roster is one line shorter per routed name**, and a person reading a hosts file no longer
|
||||
finds names that resolve to a refusal.
|
||||
- **Issue 139's second question — a per-node route holder — is left open**, and is a decision about
|
||||
what a seat is rather than about a name.

# 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 |

# 153. The record is read by a module the mesh assigns, and the console lists it
|
||||
|
||||
## Context
|
||||
|
||||
[ADR 0025](0025-the-design-record-is-read-not-copied.md) decided that this repository is **read where
|
||||
it is written, never copied to be found**: an agent reads it directly, and a search of the mesh's
|
||||
memory consults that agent so its answers appear beside ordinary results. It named the check that
|
||||
closes [issue 006](../04-ISSUES/006-hq-is-not-indexed-into-the-knowledge-base/00-report.md): search
|
||||
for a phrase that appears only in a design document here, and get it back. It gated the build on an
|
||||
agent that did not exist — the mesh session of
|
||||
[15 — The agent session](../03-DESIGN/01-to-be/15-the-agent-session.md) — and on a search that
|
||||
does not exist either, now: the knowledge base 0025 meant was the predecessor's, and since the
|
||||
cut-over nothing reaches it ([issue 147](../04-ISSUES/147-the-operators-tools-still-dial-the-bus-that-was-removed/00-report.md)).
|
||||
|
||||
**So the two halves of 0025 have no home.** There is no store to be "beside", and no session to be
|
||||
the reader. What the mesh has instead, since today: a tool model in which every module answers what
|
||||
it serves, and a console on the machine a person sits at that lists every tool the running modules
|
||||
answer ([ADR 0152](0152-the-operators-surface-is-a-module-the-console.md)). An agent holding the
|
||||
console does not search a store; it reads a tool list and calls what fits the question.
|
||||
|
||||
**What 0025 could not tolerate was a derived copy** — the enforced copy winning while the reasoned one
|
||||
quietly stops being true. It rejected a sync for that reason and for no other. A git checkout is not a
|
||||
derived copy: it is the same bytes at a commit the answer names, and the only way it can differ from
|
||||
the source is by lagging behind it, which is measurable and stated. 0025's own words allow it —
|
||||
*retrieval is an agent reading this repository, not a copy living in a second store* — and the
|
||||
transformation that makes a copy dangerous is exactly what a checkout does not do.
|
||||
|
||||
## Considered Options
|
||||
|
||||
**1. Wait for the mesh session.** Rejected. Design 15 is `designed` with nothing built, its model
|
||||
access is a provisions question with no consumer identity yet, and 006 has waited since 2026-08-23.
|
||||
A record whose check cannot run is a rule enforced by nothing.
|
||||
|
||||
**2. The console reads the repository itself.** Rejected. The console holds nothing and decides
|
||||
nothing (ADR 0152, ADR 0035); a reader inside it would be a second implementation of a thing that
|
||||
should be one module, unavailable to a person's client and to any other module.
|
||||
|
||||
**3. A module that keeps a checkout of the repository and answers questions about it, listed by the
|
||||
console like any tool.** Chosen.
|
||||
|
||||
## Decision
|
||||
|
||||
**The reader is a module: `records`.** It requires the `git` provision — the forge — clones the
|
||||
repository its settings name, keeps the checkout current on every merge the forge announces and on a
|
||||
timer, and answers over the bus: where a phrase appears as written (document, line, nearest heading),
|
||||
one document whole, what a folder holds, and where the checkout stands — always with the commit it
|
||||
read. Nothing is indexed, ranked or summarised: a design record is found by its own words, and a
|
||||
reader deciding which words matter would be a second opinion about somebody else's document.
|
||||
|
||||
**The repository is a setting, not a manifest field.** The module names no mesh
|
||||
([ADR 0112](0112-a-module-definition-names-no-node-mesh-or-path.md)): which repository it reads is
|
||||
the assignment's business, and an installation that keeps its record elsewhere sets that. Until a
|
||||
repository is set it serves no tools and says why. Public repositories only; it asks for no
|
||||
credential, because a secret it did not need would be one more thing to seal.
|
||||
|
||||
**"Beside everything else" is the console's tool list.** 0025's second half — the search consults the
|
||||
agent — has no store to consult and needs none: the console lists `records_search` beside the forge's
|
||||
tools and the mesh's own verbs, with a description that says when to call it, and an agent choosing
|
||||
tools for a symptom is the search. That is surfacing, not merely reaching: nobody has to know this
|
||||
repository exists to be offered it.
|
||||
|
||||
**Reading stays one-way.** The module reads the forge and answers; nothing flows back into the
|
||||
repository. It holds no credential that could write.
|
||||
|
||||
**The mesh session, when it exists, is a caller of this module, not a replacement for it.** Design 15's
|
||||
*it holds the design record by reading it* is satisfied by asking `records`; the session brings
|
||||
judgement, this brings the text.
|
||||
|
||||
## Consequences
|
||||
|
||||
- **Issue 006 closes on 0025's own check**, run through the console: `records_search` for a phrase
|
||||
that appears in one design document here returns that document. The module's test does the same
|
||||
against a repository it makes.
|
||||
- **The as-is knowledge document is rewritten.** [`07-knowledge.md`](../03-DESIGN/00-as-is/07-knowledge.md)
|
||||
described the predecessor's two stores; neither is reachable from the mesh, and what the mesh knows
|
||||
is now what its modules answer. Saying otherwise is the failure this repository exists to name.
|
||||
- **A checkout lags.** Between a merge and the next sync — seconds when the forge announces it,
|
||||
minutes when it does not — an answer is the previous commit's, and says which. That is the cost of
|
||||
no copy, and it is a number rather than a silence.
|
||||
- **The reader depends on the forge module's event, by name.** `consumes: gitea.pull.merged` names a
|
||||
module rather than the `git` seat, because the seat declares no events. A forge that is not gitea
|
||||
leaves the timer as the only refresh, which still works.
|
||||
- **What got harder:** the record is now reachable from every machine holding a console, which is what
|
||||
was wanted, and a reader must remember that this repository is public and the mesh is not — the
|
||||
module reads the public repository and nothing about the installation.
|
||||
|
||||
## How this is checked
|
||||
|
||||
| Rule | Checked by |
|
||||
|---|---|
|
||||
| A phrase in one document comes back from where it is written, with the commit | the module's test against a repository it makes; and live, through the console |
|
||||
| A merge on the origin is pulled and the next answer names the new commit | the same test |
|
||||
| A path outside the checkout is refused, not resolved | a test per shape |
|
||||
| A failed sync leaves the checkout standing and is said | a test against an unreachable origin |
|
||||
| Without a repository set, no tools are served and the log says why | the module's own start |
|
||||
| The console lists `records_search` beside every other tool | the console's listing, live |

# 154. The mesh's own verbs are the mesh-controller seat's tools, and which verbs those are
|
||||
|
||||
## Context
|
||||
|
||||
[ADR 0132](0132-a-seat-carries-the-tools-its-holder-must-serve.md) decided that a seat's protocol
|
||||
carries its tools in full, that holding a seat means serving them, and that the mesh's own verbs are
|
||||
the `mesh-controller` seat's. It named three prerequisites, none in place: the protocol in the store
|
||||
rather than in compiled defaults; a protocol richer than a list of verbs; a node-scoped seat's subject
|
||||
carrying the node. And it left one thing to a decision per seat: **which verbs each seat serves**,
|
||||
because a seat's tools bind every future holder.
|
||||
|
||||
The console shipped the same day ([ADR 0152](0152-the-operators-surface-is-a-module-the-console.md))
|
||||
and made the gap visible from the operator's chair: a person on a workstation could call every tool a
|
||||
*module* serves and none of the mesh's own. What a node runs, what is assigned, whether a push
|
||||
applied — the questions issue 147 opened with — still meant a shell on the control node. The console's
|
||||
own handshake said so.
|
||||
|
||||
The control plane already answers every one of those questions, as commands: `status --json`,
|
||||
`node show`, `plan --json`, `assign`, `push`. [ADR 0035](0035-one-implementation-several-surfaces.md)
|
||||
says a surface is an adapter over those with no decisions in it, and the `api` verb proves the shape:
|
||||
every route calls the function the command line calls.
|
||||
|
||||
## Considered Options
|
||||
|
||||
**1. Leave the mesh's verbs to the shell until an identity provider authenticates the HTTP API.**
|
||||
Rejected. The authenticated network surface is for a browser on another machine; the console is
|
||||
already behind the machine's login (0152), and the bus already carries every other tool call under an
|
||||
account whose permission list says what it may ask. Waiting would keep the one surface the mesh has
|
||||
from answering the mesh's own questions, for a reason that does not apply to it.
|
||||
|
||||
**2. Serve the verbs as the mesh-controller *module's* tools, `mesh.mod.mesh-controller.tool.<verb>`.**
|
||||
Rejected; 0132 rejected it already. The controller holds a seat, and the verbs must keep their address
|
||||
while the control plane is being replaced, which is the moment they are most needed. A module's name
|
||||
would change with the implementation; the seat's does not.
|
||||
|
||||
**3. Call each command's function inside the serving process.** Rejected on two facts: the commands
|
||||
print, to the process's standard output, and two calls answered at once would read each other's
|
||||
words; and each command opens and closes its own stores, which the serving process holds open. Making
|
||||
every command return a value is the larger refactor, and it would give the tools a second code path to
|
||||
keep in step with the command line — the thing ADR 0035 forbids.
|
||||
|
||||
**4. The holder of the seat runs the command it names, in its own binary, and answers what it
|
||||
printed.** Chosen.
|
||||
|
||||
## Decision
|
||||
|
||||
**The `mesh-controller` seat serves twelve verbs**, and these are its interface, additive within a
|
||||
version ([33 — The tools the mesh answers](../03-DESIGN/01-to-be/33-the-tools-the-mesh-answers.md) §7):
|
||||
|
||||
| verb | answers with | takes |
|
||||
|---|---|---|
|
||||
| `tools` | every seat's tools, from the mesh's records | nothing |
|
||||
| `status` | what is wrong, quiet, behind, waiting — `status --json` | nothing |
|
||||
| `nodes` | every machine and its mode | nothing |
|
||||
| `node` | what one machine reported, what it is assigned, why | `node` |
|
||||
| `modules` | every module, its version, commit and machines | nothing |
|
||||
| `seats` | every seat, what it delivers, who holds it — `seats --json` | nothing |
|
||||
| `builds` | what was built lately and what came of it | `module` (optional) |
|
||||
| `plan` | the declaration a machine would be sent — `plan --json` | `node` |
|
||||
| `assign`, `unassign` | the mesh's own words, refusal included | `node`, `module` |
|
||||
| `push` | that it was sent; `status` says what the machine did | `node` (optional: every machine behind) |
|
||||
| `build` | that the build machine was asked; `builds` says what came of it | `repository`, `path`, `ref` |
|
||||
|
||||
**Each verb runs the command it names, in the controller's own binary, and answers what the command
|
||||
printed** — the output, whether it succeeded, and, where the command speaks JSON, the same as data. A
|
||||
refusal is the command's refusal in the command's words, because it is the same output. A verb takes
|
||||
only the arguments its schema names; nothing reaches a flag the schema did not declare. `push` and
|
||||
`build` are sent and not waited for: a call that blocked for a whole apply would time out on every
|
||||
machine that takes a minute and say nothing about the others.
|
||||
|
||||
**The three prerequisites are built.** A seat's protocol is three columns on its row, seeded from the
|
||||
compiled defaults where a row had none and additively thereafter, so a verb a release adds joins the
|
||||
row and nothing an operator wrote is taken away. A served verb is its name, what it does, and the
|
||||
schema of its arguments and answer; a manifest may still write a bare name. A node-scoped seat's tool
|
||||
carries the node it is asked of, as the last token of its subject; a mesh-scoped seat's stays flat.
|
||||
|
||||
**Holding a mesh seat requires serving its verbs**, judged where the store's set is loaded, and the
|
||||
refusal names the missing verbs. The controller's own manifest lists the twelve under `tools`.
|
||||
|
||||
**Discovery reads the records, through the seat.** `tools` is one of the twelve because the console
|
||||
cannot read the store and should not: the mesh answers for its own records through the role that owns
|
||||
them, and the answer is true while any *other* holder restarts. It is not true while the control plane
|
||||
itself restarts, and the console says so rather than hiding the modules' tools with it.
|
||||
|
||||
**A grant of `*` reaches a role's tools; `seat:<seat>.<verb>` grants one.** The console's `*` needed no
|
||||
change to reach the mesh's verbs, which is what a grant meaning *every tool* should mean.
|
||||
|
||||
## Consequences
|
||||
|
||||
- **The console answers the mesh's own questions.** Issue 147's first paragraph closes: what a node
|
||||
runs, what is assigned, whether a push applied, from the machine the person sits at, over the bus,
|
||||
under an account whose permission list says so.
|
||||
- **Whoever may call `mesh-controller.push` may change the mesh.** That is the console's `*` on a
|
||||
machine whose login owns the mesh (0152), and a person's account only if `operator issue` says so.
|
||||
A grant reviewer reads `*` and `seat:mesh-controller.` with the same care.
|
||||
- **A verb here binds every future controller.** Twelve is deliberate: what an operator asks weekly,
|
||||
and nothing that is still finding its shape (`take`, `converge`, `settings`, `secret` stay commands).
|
||||
- **A command's text is the answer**, and text changes. The three verbs that speak JSON carry it as
|
||||
data; the rest are read by a person or an agent, not parsed. Anything that needs a shape asks for
|
||||
`--json` to be added to the command first, which is the right order.
|
||||
- **What got harder:** the mesh-controller seat's row now carries a protocol an operator could edit, and
|
||||
a verb removed from the row is a verb the controller stops serving without a build. That is
|
||||
ADR 0122's arrangement applied to tools, and `seats` shows the row.
|
||||
|
||||
## How this is checked
|
||||
|
||||
| Rule | Checked by |
|
||||
|---|---|
|
||||
| Every declared verb is one the binary can run, with the arguments its schema names | a test walks the table and derives a command line for each |
|
||||
| A verb missing a required argument is refused in its own words, before anything runs | a test per shape |
|
||||
| A holder that does not serve a mesh seat's verbs cannot hold it, and the refusal names them | a catalogue test against a seat with two verbs and a holder with one |
|
||||
| A node-scoped seat's tool carries the node; a mesh seat's does not | the bus composition test: two nodes derive two addresses |
|
||||
| The controller subscribes its seat's tools and may answer | the composition test, and the golden user list |
|
||||
| `*` reaches a role's tools; `seat:` grants one and refuses a name with no verb | the composition test |
|
||||
| The protocol is seeded into the row and widened additively | the store-backed seat test |
|
||||
| Live: the console lists `mesh-controller.status` and a call answers what `status --json` prints | the rollout of this record |

# 155. A definition names no installation: how that is checked, and the three ways a value that did gets out
|
||||
|
||||
## Context
|
||||
|
||||
[ADR 0112](0112-a-module-definition-names-no-node-mesh-or-path.md) decided that a module definition
|
||||
names no node, no mesh and no host path, and said how the name half is checked: *a catalogue test
|
||||
finds no domain name in any definition value*. No such test existed
|
||||
([issue 134](../04-ISSUES/134-a-definition-may-still-name-the-mesh/00-report.md)). Written and run
|
||||
over the 77 definitions on 2026-09-30, the check it describes finds **42 values**, in 15 definitions,
|
||||
and they are of four kinds that want four different answers:
|
||||
|
||||
| kind | count | example |
|
||||
|---|---|---|
|
||||
| a service told its own public name as a literal | 5 | an identity provider's `KC_HOSTNAME`, an object store's console redirect, an automation tool's webhook URL |
|
||||
| an operator's value written into the definition | 10 | a mail server's domain, site name, website, and the address it trusts a real-IP header from |
|
||||
| this mesh's forge, by URL, as a recipe's build context | 2 | the builder and the proxy, which package the controller's source |
|
||||
| an application built outside the mesh, pulled from this mesh's registry | 7 | four sites and tools whose repositories are the operator's own |
|
||||
| the world's servers, named by upstream defaults | 10 | a Matrix homeserver's trusted key server, Element's integration manager |
|
||||
| a module named after the domain it serves | 8 | one site module, with its paths and network named after it |
|
||||
|
||||
Not one was careless. Each was the value the software needs, and until today there was nowhere else
|
||||
to put it ([issue 122](../04-ISSUES/122-a-module-cannot-ask-for-its-own-public-name/00-report.md)).
|
||||
Two of the answers were built before this record: a module is told the name its route composes
|
||||
(`${bound:<route>:name}`, controller PR 149, 2026-09-30), and a source may be a path on the git seat
|
||||
([ADR 0111](0111-a-build-source-is-on-the-git-seat-or-external.md)). What was missing: an operator's
|
||||
value in a file the software reads, the same for a build *context*, a way to say a name is meant, and
|
||||
the check.
|
||||
|
||||
## Considered Options
|
||||
|
||||
**1. A string search for the installation's own names.** Rejected. The controller is as
|
||||
mesh-agnostic as the definitions; it does not know which names are "this mesh's", and a check that had
|
||||
to be told would be configured per installation and pass everywhere else. What it can know is the
|
||||
*shape*: a name under a public top-level domain, a public address.
|
||||
|
||||
**2. Report every such shape.** Rejected. Eight of the 42 were `why` strings — prose the mesh never
|
||||
reads, explaining what a port is for — and a check that reports those beside `KC_HOSTNAME` teaches
|
||||
people to ignore the report. And a Matrix homeserver *must* name the federation's public key server;
|
||||
a check with no way to say so would be a check people argue with rather than obey.
|
||||
|
||||
**3. Judge what the mesh acts on; let a definition say which names it means, one by one, with a
|
||||
reason; exempt the world's services that a definition may name as a policy default.** Chosen.
|
||||
|
||||
**For an operator's value**, one option was to wait for design 27's requirement form in full. Rejected
|
||||
for the reason 0112 gave against a slow operator provider: if asking a person for a value takes more
|
||||
than a setting, module authors route around it and the literals come back. `${setting:<key>}` is the
|
||||
operator provider in its first form, on the settings a module already has.
|
||||
|
||||
## Decision
|
||||
|
||||
**The check.** Every string value of a definition that the mesh acts on is judged for a hostname under
|
||||
a public top-level domain and for a public address. Not judged: `why` and `description`, which are
|
||||
prose. Allowed where they can only mean the world: the public registries an `image` may be pulled
|
||||
from, the public resolvers a machine may forward to, and the public certificate authorities' ACME
|
||||
directories. The container runtime's alias for its own host is the runtime's. A module's own name is a
|
||||
value too. The check runs in `module check` and as a catalogue-wide test; **it does not yet refuse at
|
||||
registration**, because the list it prints is the list that shrinks, and a registration that refused a
|
||||
manifest whose only remedy is a merge elsewhere would refuse the mesh's own catalogue on the day the
|
||||
check landed. It moves to registration when the list has been empty for a release.
|
||||
|
||||
> **Progressive insight — 2026-09-30.** The list was empty the day the check landed — every remaining name declared with its reason — and the operator asked for registration to refuse at once rather than after a release. It does, since mesh-controller PR 175: `module add` and a build's result are refused in the check's words, naming the way out, and the build stays recorded. The decision stands; only the day moved.
|
||||
|
||||
**A name a definition means is declared with its reason.** `names-on-purpose` on a resource maps each
|
||||
such name to why: *the federation's public key server, the world's*; *built outside the mesh, from the
|
||||
application's own repository, until that repository is a build source on the git seat*. A name the map
|
||||
does not cover is still reported. The host never sees the word.
|
||||
|
||||
**An operator's value reaches a file as `${setting:<key>}`**, filled from the module's settings
|
||||
layers — the mesh's, then the node's — the same layers a mergeable file and a contribution take, so
|
||||
`settings set <module>` stays the one place a person's values go. Refused, naming the key and the
|
||||
command, when nothing set it: a default for a mail domain would be the literal this removes, and a
|
||||
blank written silently would be a service that comes up wrong somewhere that names nothing.
|
||||
|
||||
**A build context may live on the git seat.** `context: {"seat": "git", "repository": "<owner>/<name>"}`
|
||||
is composed by the mesh that builds it: the request carries each seat's clone base, and a builder told
|
||||
no base for a seat a context names refuses the build by the seat's name rather than guessing a forge.
|
||||
|
||||
**A module is named for what it is.** The site module named after its domain is `website`.
|
||||
|
||||
## Consequences
|
||||
|
||||
- **The catalogue names no installation, and a test says so.** The forty-two became zero the same day,
|
||||
by the four answers above; seven of them are declared on purpose and stay visible as the list to
|
||||
shrink — four applications the mesh does not build yet.
|
||||
- **An operator's values are the assignment's.** The mail module takes its domain, its site name, its
|
||||
website and the address it trusts a real-IP header from as settings; a mesh that installs it without
|
||||
them is refused at composition, by name, which is the right moment. The module's own README says
|
||||
which.
|
||||
- **What got harder:** a manifest reviewer has one more word to read, and `names-on-purpose` on an
|
||||
application's image is a debt visible in the definition until the application is built here. A
|
||||
reader of `settings set` output sees more keys than files, because a key a file asks for is a
|
||||
destination too.
|
||||
- **Not decided here:** ADR 0112's requirement form (design 27) still replaces `${setting:…}` and the
|
||||
other placeholders when it lands; this is its first case, the way [ADR 0038](0038-the-mesh-assigns-the-port.md)
|
||||
was for ports. Host paths ([issue 119](../04-ISSUES/119-a-module-definition-decides-where-its-files-live/00-report.md))
|
||||
are the next step of the same group, and the registry's name ([issue 123](../04-ISSUES/123-the-image-registry-is-named-after-a-role/00-report.md))
|
||||
the one after.
|
||||
|
||||
## How this is checked
|
||||
|
||||
| Rule | Checked by |
|
||||
|---|---|
|
||||
| A value naming an installation is reported at its path, in the definition's words | a catalogue unit test over a definition with a hostname in an env value and a public address in a file |
|
||||
| Prose, the world's registries in an image, public resolvers, ACME directories and the runtime's own alias are not reported | the same tests |
|
||||
| A name declared on purpose is not reported; a name beside it that is not declared is | a test with a homeserver's config |
|
||||
| An image from an installation's registry needs a reason | a test without and with the word |
|
||||
| A module named after a domain is reported | a test |
|
||||
| No definition in the catalogue names an installation | `TestNoCatalogueManifestNamesAnInstallation` over the checkout, and `module check modules/` |
|
||||
| A definition naming an installation is refused at registration, and one declaring its names passes | `TestRegistrationRefusesADefinitionNamingAnInstallation` (2026-09-30) |
|
||||
| `${setting:key}` fills from the layers, node over mesh; refused by name when unset; not stray when set | three tests |
|
||||
| A context on a seat is cloned from the base the mesh sent; a seat with no base is refused by name | the builder's test |

# 156. An artifact is what a build produces, the artifact store serves every kind, and its seat is named for its scope
|
||||
|
||||
## Context
|
||||
|
||||
[Issue 123](../04-ISSUES/123-the-image-registry-is-named-after-a-role/00-report.md) found three
|
||||
wordings disagreeing about the mesh's registry. The glossary defined *artifact* as "an OCI image, by
|
||||
digest"; the manifest's build vocabulary names four kinds — `image`, `upstream`, `bundle`, `archive` —
|
||||
and the catalogue builds all four; the seat was `the-artifact-store`, the last of the mesh's own seats
|
||||
named after the job it does rather than for the mesh
|
||||
([ADR 0121](0121-a-system-seat-is-named-for-its-scope-and-modules-define-their-own.md) decided the
|
||||
rename and deferred it). The issue asked whether the seat and provision should be renamed after
|
||||
images, and whether the mesh needs two registry implementations at all.
|
||||
|
||||
Reading what the store actually serves settles the first question the other way. A kept reference
|
||||
has two shapes — `artifact-store://<module>/<artifact>@sha256:…` for an image and
|
||||
`artifact-store://<module>/<artifact>/blobs/sha256:…` for an archive — and both are served by the
|
||||
same OCI registry, by digest. [ADR 0075](0075-two-stores-and-which-provides-what.md) already
|
||||
defined the provision that way: *content-addressed blobs, pinned by digest, no versions, no ranges;
|
||||
what the mesh delivers to machines*. The provision was never an image registry. Only the glossary said
|
||||
so, and only the seat's name was odd.
|
||||
|
||||
## Considered Options
|
||||
|
||||
**1. Rename the seat and the provision after images.** Rejected. The store serves archives too, by the
|
||||
same protocol; naming it for one kind would be the glossary's mistake made permanent, in the name
|
||||
every manifest uses.
|
||||
|
||||
**2. Fix the word, rename the seat for its scope, keep the provision.** Chosen. The rename ADR 0121
|
||||
deferred as a delivering-seat migration is, since [ADR 0122](0122-a-seat-is-data-a-rename-is-a-database-update.md),
|
||||
one update and one alias: the former name resolves forever, a held record follows by cascade, a claim
|
||||
written with the old name still holds.
|
||||
|
||||
**On two implementations:** left as 0075 decided. Two provisions because two protocols; the OCI
|
||||
registry the genesis installs because something must serve images before the mesh can build; the
|
||||
forge may provide `artifact-store` too and a mesh may choose it. The bootstrap argument is weaker than
|
||||
it reads, as 123 says, and the day the forge is raised at genesis and adopted in place is the day to
|
||||
retire the second server — a migration a mesh performs, not a decision to take here.
|
||||
|
||||
## Decision
|
||||
|
||||
- **An artifact is anything a build produces** — an image, a mirrored upstream image, a bundle, an
|
||||
archive — and the glossary says so. *Image* is one kind. A module is not an image; a module may
|
||||
build several artifacts and install none.
|
||||
- **The artifact store serves artifacts of every kind a machine fetches**, images and archives, by
|
||||
digest, over the OCI registry protocol. The provision keeps its name.
|
||||
- **The seat is `mesh-artifact-store`.** `the-artifact-store` is its alias. The catalogue's registry
|
||||
module claims the new name; a definition elsewhere claiming the old one still holds.
|
||||
- The two other deferred renames — `npm-package-registry` and `git` — stay deferred, and for the
|
||||
same reason no longer. They are one migration each when wanted; nothing here needs them.
|
||||
|
||||
## Consequences
|
||||
|
||||
- The glossary stops contradicting the manifest vocabulary, and a reader of `artifact-store` reads
|
||||
it as what it is: where the mesh's built things are kept.
|
||||
- One migration on the seat table; no manifest but the registry's changes; no consumer of the
|
||||
provision changes, because the provision did not.
|
||||
- **What got harder:** nothing measurable. A record that says `the-artifact-store` is read through the
|
||||
alias; design 26's table already carried the new name as intent.
|
||||
|
||||
## How this is checked
|
||||
|
||||
| Rule | Checked by |
|
||||
|---|---|
|
||||
| The former name resolves to the seat once the store's aliases are loaded | a catalogue test |
|
||||
| The seat is in the compiled set under its new name, delivering `artifact-store` | the seat tests, updated |
|
||||
| The registry module holds the seat under the new name on the live mesh | `seats` after the rollout |
|
||||
| The glossary's *artifact* matches the build kinds a manifest may declare | design 18's table and the showcase module list the kinds; the glossary names the same four |

# 157. A build says what it does on the bus, as it happens
|
||||
|
||||
## Context
|
||||
|
||||
[ADR 0121](0121-a-system-seat-is-named-for-its-scope-and-modules-define-their-own.md) made a build work submitted to a role: the
|
||||
build-machine seat accepts a build and emits its outcome, one publish that reaches whoever asked, the
|
||||
controller that records it and the catalogue that places it. Everything **between** the request and
|
||||
the outcome — which command is running, how long it has taken, where it hung, the compiler's error,
|
||||
the clone's refusal — lived in one container's standard error on one machine.
|
||||
|
||||
The night of 2026-09-30 showed the cost three times over. A build that failed showed a person one
|
||||
line, the first of its failure, in the controller's `builds`; the rest was read with `docker logs` over
|
||||
ssh, which the mesh's own rule forbids. A build that ran for minutes could not be told from one that
|
||||
had hung. And the builder has no tools and emits nothing but the outcome, so the console
|
||||
([ADR 0152](0152-the-operators-surface-is-a-module-the-console.md)) had nothing to show while a
|
||||
build ran, and no viewer could be built on top of it. The operator's ask was plain: the builder is to
|
||||
be fully transparent, with its log on the bus, so that a log viewer can be built on the bus later.
|
||||
|
||||
## Considered Options
|
||||
|
||||
1. **Keep the log in the outcome.** The result carries the whole log when the build ends. Nothing new
|
||||
on the bus; nothing while the build runs; a viewer sees a build only once it is over, which is
|
||||
exactly when the log matters least.
|
||||
2. **A log store.** The builder writes its log to a file or a table and a tool reads it. A second
|
||||
place to keep something the bus already carries, with its own retention, access and failure modes,
|
||||
and no live reading without inventing a subscription over it.
|
||||
3. **The log is the role's own events.** Two more events on the build-machine seat beside `built`:
|
||||
`started` when work is taken, and `log.<build id>` for every line, published as the build runs.
|
||||
The events stream already retains every role's events for a week, so a reader follows a build
|
||||
live by subscribing its subject, or reads it back afterwards from the stream, and a viewer is a
|
||||
subscriber and nothing more.
|
||||
|
||||
## Decision
|
||||
|
||||
**Option 3.** A build machine says everything it does on the bus, as the role it holds, under the
|
||||
build's id, and the mesh keeps no other copy.
|
||||
|
||||
- The build-machine seat's protocol gains `started` and `log.*`. A holder may therefore publish
|
||||
`mesh.seat.mesh-build-machine.event.started` and `…event.log.<id>`, and no other subject, by the
|
||||
same derivation every seat's grants follow ([ADR 0132](0132-a-seat-carries-the-tools-its-holder-must-serve.md)).
|
||||
The event's tail token is the build's id, so one build is one subject: a reader filters by subject
|
||||
alone, on the server, and a week of other builds does not travel to show one.
|
||||
- **Every line goes two ways**: to the machine's own standard error as before, and onto the bus. That
|
||||
includes every command the builder runs, its duration and its failure, and on failure the command's
|
||||
own output line by line — the compiler's words, the clone's refusal. A build machine with nobody
|
||||
listening still prints; a listener reads the same lines.
|
||||
- A line is a core publish, unawaited. The stream that holds the role's events captures it on its way
|
||||
through, and a build does not slow to the pace of an acknowledgement per line. Each line carries a
|
||||
sequence number from one, so a reader who joined late, or reads two copies, sees order and gaps.
|
||||
`started` and `built` are published into the stream and awaited, because they are the two facts a
|
||||
later reader must never find missing.
|
||||
- **The mesh reads it back from the stream**, never from a record of its own: `builds --log <id>`, and
|
||||
the same verb on the controller's seat ([ADR 0154](0154-the-meshs-own-verbs-are-the-controller-seats-tools.md)),
|
||||
reads one build's subject with a consumer that is gone when the reading is done. `builds` lists
|
||||
each build's id beside it, and `build` says the id it asked with, so a person can follow.
|
||||
- Nothing is declared by the builder module for this. The protocol is the seat's, seeded additively
|
||||
into the store ([ADR 0132](0132-a-seat-carries-the-tools-its-holder-must-serve.md)), and the
|
||||
holder's grant follows on the next composition of the broker node.
|
||||
|
||||
## Consequences
|
||||
|
||||
- A build is watchable while it runs, from anywhere on the mesh, with no access to the build machine.
|
||||
The console's gap of 2026-10-01 — no live progress, no per-merge view — closes on the progress half;
|
||||
the per-merge view is a reader over these subjects and the outcome, and is not built here.
|
||||
- A log viewer on the bus is now a plain subscriber: live on `mesh.seat.mesh-build-machine.event.>`,
|
||||
historical from the events stream filtered by a build's subject. NATS carries and retains; it does
|
||||
not view. The `nats` command-line client can tail or replay a subject today; a viewer of our own is
|
||||
later work and needs nothing more from the builder.
|
||||
- The events stream grows by a build's log per build, for a week. A build is a few hundred lines; the
|
||||
stream's limits are the bound, as for every other event, and a stream that fills drops the oldest.
|
||||
- A line the bus did not take is lost, deliberately, and visible as a gap in the sequence. The outcome
|
||||
is not affected: a build's result never depended on its narration.
|
||||
|
||||
## How this is checked
|
||||
|
||||
| Rule | Checked by |
|
||||
|---|---|
|
||||
| The seat's holder may publish `started` and `log.<id>` and nothing wider | `TestTheBuildMachineMaySayWhatItDoesUnderTheBuildsId` (broker) |
|
||||
| A build's lines reach a reader of its subject in order, and the stream holds them afterwards | `TestNatsABuildIsTakenAndItsOutcomeReachesEverybody` against a real server (link) |
|
||||
| The seat verb `builds` with a build's id reads that build's log | `TestBuildsWithAnIdReadsThatBuildsLog` |
|
||||
| Every command the builder runs is said, with its output on failure | `Command` speaks through the hook every build sets; the builder's tests still see the lines on standard error when nothing listens |
|
||||
| Live: a build triggered after the roll-out is readable line by line through the console | done by hand after the merge of mesh-controller PR — see the design's note |

# Knowledge
|
||||
|
||||
The mesh keeps two knowledge stores. They are not redundant, and knowing which is which is the
|
||||
difference between finding an answer in one search and rediscovering it over several hours.
|
||||
**The mesh keeps no knowledge store.** What it knows is what its modules answer, and the way a person
|
||||
or an agent asks is the console's tool list on the machine they sit at
|
||||
([13 — The console](13-the-console.md)). This document used to describe two stores; it is rewritten
|
||||
because neither exists from the mesh's side, and an as-is document that describes what is gone is a
|
||||
brochure.
|
||||
|
||||
## The operational memory
|
||||
## What was here, and where it went
|
||||
|
||||
A store of operational notes, written and read by whoever — human or agent — is working. Each
|
||||
note is a slug and a body: how something works, what went wrong, what the fix was, what
|
||||
assumption turned out to be false.
|
||||
Until the cut-over of 2026-09-28 the predecessor ran two stores: an operational memory of notes
|
||||
indexed on symptoms, and a structured archive of governed documents with a librarian approving
|
||||
promotion. Both were reached through the predecessor's tool server over the bus the mesh removed
|
||||
([issue 147](../../04-ISSUES/147-the-operators-tools-still-dial-the-bus-that-was-removed/00-report.md)).
|
||||
Nothing in the mesh reaches them now, and nothing in the mesh has replaced them: there is no note
|
||||
store, no archive, no librarian, and the lessons of the last days were written into this repository by
|
||||
hand. That is a gap, and it is stated here rather than papered over. What replaces a symptom-indexed
|
||||
memory, if anything does, is undecided.
|
||||
|
||||
It is indexed on **symptoms**. The entry someone needs is usually titled after the error they
|
||||
are staring at, which is why the standing instruction is to search the literal error text
|
||||
before forming a hypothesis rather than after one fails.
|
||||
## The record
|
||||
|
||||
Its content is overwhelmingly the record of previous debugging: a large body of
|
||||
troubleshooting entries, module conventions, and standing notes about work that is open. It is
|
||||
the mesh's institutional memory of *what has already gone wrong*.
|
||||
**The design record is read where it is written.** Since 2026-09-30 a module, `records`, keeps a
|
||||
checkout of this repository from the forge — cloned from the `git` seat, reset to the origin on every
|
||||
merge the forge announces and every ten minutes — and answers over the bus: where a phrase appears as
|
||||
written, one document whole, what a folder holds, and where the checkout stands, each naming the
|
||||
commit it read. Which repository it reads is a setting on its assignment; the module names no mesh.
|
||||
|
||||
The cost of skipping it is documented in the mesh's own record: entries have been rediscovered
|
||||
from scratch, over hours, in sessions where the search was skipped because the trail felt
|
||||
confident. It fires hardest on familiar ground, not unfamiliar ground.
|
||||
It is listed by the console beside every other tool, with a description that says to search the
|
||||
literal words of a symptom before forming a hypothesis. That is what
|
||||
[ADR 0025](../../02-DECISIONS/0025-the-design-record-is-read-not-copied.md) meant by *beside
|
||||
everything else*, in a mesh with no store to be beside
|
||||
([ADR 0153](../../02-DECISIONS/0153-the-record-is-read-by-a-module-and-the-console-lists-it.md)).
|
||||
|
||||
## The structured archive
|
||||
Nothing is copied. A checkout lags the source by seconds after an announced merge and by minutes
|
||||
otherwise, and says so.
|
||||
|
||||
A second store, structured rather than flat: spaces, pages, revisions, tiers, and full-text
|
||||
search. Where the operational memory is a note, this is a document with an owner and a
|
||||
lifecycle.
|
||||
## The constitution
|
||||
|
||||
Content is promoted through tiers — private, then team, then platform — with a librarian agent
|
||||
owning approval and promotion at the boundary. Proposals to edit are reviewed rather than
|
||||
applied.
|
||||
|
||||
This is where the mesh's **governed** documents live, including the constitution injected into
|
||||
design sessions ([ADR 0020](../../02-DECISIONS/0020-the-mesh-is-governed-by-a-constitution.md)).
|
||||
|
||||
## Why both
|
||||
|
||||
The distinction is by lifecycle, not by subject.
|
||||
|
||||
| Operational memory | Structured archive |
|
||||
|---|---|
|
||||
| Written the moment something is learned | Written deliberately, reviewed |
|
||||
| Flat, symptom-indexed | Structured, tiered, owned |
|
||||
| Anyone writes; nothing approves | Promotion is approved |
|
||||
| Truth is "this happened" | Truth is "this is agreed" |
|
||||
|
||||
Collapsing them would cost one of the two properties: either every hard-won note waits for
|
||||
review, or governed documents can be changed by anyone mid-incident.
|
||||
[`00-META/how-we-build.md`](../../00-META/how-we-build.md) is the source of the mesh constitution
|
||||
([ADR 0021](../../02-DECISIONS/0021-hq-is-the-source-of-the-constitution.md)). The page it used to be
|
||||
synchronised into lived in the predecessor's archive and is unreachable; the constitution today is
|
||||
read from this repository, through the same module, and playbook 05's sync has nothing to write to.
|
||||
|
||||
## Where this repository sits
|
||||
|
||||
This repository is a third thing, and the objection was raised when it was created: a fourth
|
||||
knowledge system repeats the mistake the split was made to fix.
|
||||
|
||||
The answer given was **indexing, not location** — that these documents are indexed into the
|
||||
knowledge base so that a symptom search returns them alongside everything else. One source,
|
||||
many surfaces.
|
||||
|
||||
**That indexing does not currently exist.** A search for this repository's content returns
|
||||
nothing. The claim is load-bearing for the decision to separate the repository at all, and
|
||||
until it is true, this repository is exactly the fourth knowledge system the objection
|
||||
described. Recorded here because it is a statement about how the mesh's knowledge actually
|
||||
works today, and as [`04-ISSUES/006`](../../04-ISSUES/006-hq-is-not-indexed-into-the-knowledge-base/00-report.md).
|
||||
|
||||
## The librarian
|
||||
|
||||
A single agent owns the archive's approvals and promotions. Its approval capabilities have at
|
||||
times not been reachable as tools, which does not affect the operational memory but does mean
|
||||
promotion stops silently — the store keeps accepting proposals that nothing can approve.
|
||||
A third thing beside two that are gone, which makes it the first: the one governed record the mesh
|
||||
has, public, read by a module the mesh assigns, and edited nowhere else.

The `seat` table carries `accepts`, `emits` and `serves`; `serves` holds each verb with its description
|
||||
and input schema. The rows were seeded from the compiled defaults the first time a controller with the
|
||||
columns migrated, and each later migration adds any verb the defaults name that a row lacks, never

removing one. `UseSeats` still falls back to the compiled protocol for a row with none, which after the

first seeding is no row.

The `mesh-controller` seat serves twelve verbs — `tools`, `status`, `nodes`, `node`, `modules`, `seats`,

`builds`, `plan`, `assign`, `unassign`, `push`, `build` — on `mesh.seat.mesh-controller.tool.<verb>`,

each answered by the controller running that command in its own binary and returning what it printed.

A module claiming a mesh seat with verbs must list them under `tools` or registration refuses it by

one yet.

# 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.
|
||||
|
||||
## The mesh's own verbs
|
||||
|
||||
*Since 2026-09-30 evening ([ADR 0154](../../02-DECISIONS/0154-the-meshs-own-verbs-are-the-controller-seats-tools.md)).*
|
||||
The console asks the `mesh-controller` seat's `tools` verb beside the modules and lists every role's
|
||||
tools as `<seat>.<verb>` — `mesh-controller.status`, `mesh-controller.push` and the other ten. A call
|
||||
to `<prefix>.<name>` reaches the seat when the prefix is a seat declaring that verb, and the module
|
||||
otherwise; `seat:<seat>.<verb>` says so outright. When the control plane does not answer, the list
|
||||
names `mesh-controller (seat)` as not answering and carries the modules' tools regardless. The
|
||||
`mesh-controller` *module* is always named as not answering: it serves no module tools, only its seat's.
|
||||
|
||||
## 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.

|
||||
|
||||
A build machine narrates every build on the bus as the role it holds: `started` when it takes the
|
||||
work, one `log.<build id>` event per line — every command it runs with its duration, every step of
|
||||
the recipe, and on failure the command's own output, line by line — and `built` for the outcome as
|
||||
before. The same lines still go to the machine's standard error, so a build machine with nobody
|
||||
listening is as readable as it was; a listener reads the same lines, live, from anywhere on the mesh.
|
||||
|
||||
One build is one subject. A reader follows it by subscribing that subject and nothing else, and the
|
||||
events stream keeps it for a week, so `builds --log <id>` — on the command line and as the
|
||||
controller's seat verb through the console — reads it back afterwards. `builds` lists every build's
|
||||
id beside it, and `build` says the id it asked with. The mesh keeps no second copy: the stream is the
|
||||
log. The console's `build` tool asks and answers at once with the id; the outcome is taken in — the
|
||||
build recorded, the module registered with its source — by whoever hears it, the waiting command or
|
||||
the daemon following the role's event, so a build nobody waited for still reaches the catalogue
|
||||
([issue 176](../../04-ISSUES/176-the-consoles-build-tool-neither-waits-nor-registers/00-report.md)). A viewer of builds, when one is built, is a subscriber over these subjects and the outcome; the

builder needs nothing more for it.

build's lines reach a reader of its subject in order and the stream holds them afterwards (link test

||||
against a real server); the seat verb with an id reads the log (controller test); and, live, a build

after the roll-out read line by line through the console.

|

console lists a role's tools beside the modules' own and resolves `<seat>.<verb>` to the seat when the

seat declares that verb. Which verbs each *other* seat serves stays a decision per seat, still untaken.

## What shipped, 2026-09-30
|
||||
|
||||
mesh-controller PRs 166 and 167, mesh-tools PR 21. Verified on the live mesh the same evening: the
|
||||
console on a workstation lists the twelve verbs as `mesh-controller.<verb>` beside 67 module tools, and
|
||||
`mesh-controller.nodes` and `mesh-controller.status` answer through it with what the commands print.
|
||||
|
||||
Two things shipped bent. **The grant arrived after the holder started**: the controller composes the
|

bus's user list and a push delivers it, so the first controller to serve its seat subscribed before
|
||||
the broker's list named the grant, the server refused all twelve subscriptions, and the client never
|
||||
retried — a holder now rebinds a refused subscription every thirty seconds (PR 167), and a controller
|
||||
roll-out that adds a grant is followed by a push to the broker node. **A JSON verb's answer was parsed
|
||||
from both output streams**, so `status --json`'s warnings hid the document as data; the answer is now

# 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.

# 35 — Reading the record
|
||||
|
||||
**The design record, answered from a checkout the mesh keeps, at the commit it read.** A module,
|
||||
`records`, holds a working copy of a repository of markdown — this one, for this mesh — and answers
|
||||
where a phrase appears, what a document says, what a folder holds and where the copy stands. The
|
||||
console lists those answers beside every other tool
|
||||
([ADR 0153](../../02-DECISIONS/0153-the-record-is-read-by-a-module-and-the-console-lists-it.md)).
|
||||
|
||||
## 1. What it keeps, and why that is not a copy
|
||||
|
||||
A git checkout, cloned from the forge that holds the `git` seat, brought up to date on every merge the
|
||||
forge announces and every ten minutes besides. The bytes are the repository's; nothing is derived
|
||||
from them and stored. What [ADR 0025](../../02-DECISIONS/0025-the-design-record-is-read-not-copied.md)
|
||||
refused was a second store that is *searched* while the first is *edited*, drifting silently. A
|
||||
checkout cannot drift; it can lag, and the lag is in every answer as the commit it was read at and
|
||||
in `records_status` as when it was last brought up to date.
|
||||
|
||||
The checkout is reset to the origin on every sync, never merged: it is the mesh's, so a local change
|
||||
is nobody's.
|
||||
|
||||
## 2. What it answers
|
||||
|
||||
| tool | answers |
|
||||
|---|---|
|
||||
| `records_search` | every place a phrase appears, as written and case-insensitively: document, line, the nearest heading above it; bounded, and says when it was |
|
||||
| `records_read` | one document, whole, or its first part with a note when very long |
|
||||
| `records_list` | what a folder holds: sub-folders and documents |
|
||||
| `records_status` | repository, forge, commit and its date, last sync, document count, last error |
|
||||
| `records_sync` | bring the checkout up to date now |
|
||||
|
||||
No ranking and no summary, on purpose: a record is found by its own words, and the reasoning is in
|
||||
the document, not in the tool.
|
||||
|
||||
## 3. What it is told, and what it refuses to guess
|
||||
|
||||
Three things, none from a manifest ([ADR 0112](../../02-DECISIONS/0112-a-module-definition-names-no-node-mesh-or-path.md)):
|
||||
the directory its checkout lives in (a resource the mesh gives it), the forge's address (the `git`
|
||||
provision's binding, written into a file as `scheme://host:port`), and the repository's path on the
|
||||
forge (a **setting**, `{"repository": "<owner>/<name>"}`). Without the third it serves no tools and its
|
||||
log says so. Public repositories only; it holds no credential.
|
||||
|
||||
## 4. How it is found
|
||||
|
||||
The console asks every module what it serves and lists `records_search` with a description that says
|
||||
when to call it — *search the literal words of a symptom or a term before forming a hypothesis*. That
|
||||
is 0025's second half in today's mesh: there is no store to be beside, and an agent choosing from a
|
||||
tool list is the search.
|
||||
|
||||
## 5. Where it runs
|
||||
|
||||
Anywhere a node has the forge in reach; one assignment is enough, and a second on another machine is
|
||||
harmless. The mesh session of design 15, when it exists, calls this rather than reading for itself.
|
||||
|
||||
## How it is checked
|
||||
|
||||
| Check | Defends |
|
||||
|---|---|
|
||||
| a phrase in one document of a repository the test makes comes back from that document, with the commit; a second commit on the origin is pulled and the next answer names it | ADR 0025's check, ADR 0153 |
|
||||
| a path outside the checkout is refused; an empty search is refused | the reader reads the repository and nothing else |
|
||||
| a sync against an unreachable origin leaves the checkout standing and says why | silence and success never look alike |
|
||||
| live: through the console, `records_search` for a phrase that appears only in a design document here returns it | issue 006's closing check |
|
||||
|
||||
## What shipped, 2026-09-30
|
||||
|
||||
mesh-catalog PR 183, then PR 185. Verified on the live mesh the same evening: `records` assigned to the
|
||||
control node with `{"repository": …}` as its setting, its checkout at the repository's `main` with 478
|
||||
documents, its five tools listed by the console beside every other tool, and — ADR 0025's check —
|
||||
`records_search` for a phrase from this document's title returned it from where it is written, with
|
||||
the commit. The first live search missed: the phrase chosen from ADR 0025 straddled a line break under
|
||||
emphasis, and the reader matched single lines. PR 185 matches a line together with the next and
|
||||
ignores emphasis marks, which the module's test now covers; until it rolls, a phrase that wraps is one
|
||||
to shorten.
|
||||
|
||||
The reader's `consumes` names the forge module's event rather than the `git` seat, because the seat
|
||||
declares none; a merge into the repository was seen and pulled within seconds.
|
||||
|
||||
## What this does not settle
|
||||
|
||||
- Ranking or meaning. A search that understands a question is the session's job, not the reader's.
|
||||
- A private repository. That is a credential the module would have to hold, and a decision about
|
||||
what may read what.

|

|

## Where this stands, 2026-09-30
|
||||
|
||||
The README no longer claims a property nothing provides: it says the indexing never existed, that the
|
||||
store it named is unreachable since the cut-over, and that ADR 0025's answer — read, not copied, by an
|
||||
agent that consults this repository — is decided and not built. That was the honest fix the previous
|
||||
note asked for, and it is done.
|
||||
|
||||
The record stays open on ADR 0025's build, and on nothing else. The mesh's own operator surface is now
|
||||
a module ([ADR 0152](../../02-DECISIONS/0152-the-operators-surface-is-a-module-the-console.md)); the
|
||||
reader ADR 0025 describes is the mesh session of design 15, which would answer through that surface
|
||||
like any tool. What closes this is still the check 0025 names: search for a phrase that appears only in
|
||||
a design document here, and get it back.
|
||||
|
||||
## Built, 2026-09-30

||||
[ADR 0153](../../02-DECISIONS/0153-the-record-is-read-by-a-module-and-the-console-lists-it.md): the
|

reader is a module, `records` (mesh-catalog PR 183), keeping a checkout of this repository from the
|
||||
forge and answering `records_search`, `records_read`, `records_list`, `records_status` and
|
||||
`records_sync` at the commit it read; the console lists them beside every other tool, which is where

## Resolved, 2026-09-30
|
||||
|

The check ADR 0025 names passed on the live mesh: through the console on a workstation,
|
||||
`records_search` for a phrase that appears in one design document here returned that document and the
|
||||
commit it was read at, from a checkout the mesh keeps and nobody copied. What this record asked on
|
||||
2026-08-23 — *does the searcher find it without already suspecting it exists?* — is answered by where
|
||||
the tool sits: in the same list as the forge's and the mesh's own, described as the thing to search
|
||||
before forming a hypothesis. Reachable became surfacing when the surface became a list.

# 107 — resolved: a declaration carries its order
|
||||
|
||||
*2026-09-30. Measured on the mesh.*
|
||||
|
||||
## What was done
|
||||
|
||||
**Hosts first, then the controller** — the order [issue 087](../087-the-controller-cannot-tell-a-host-is-too-old/00-report.md)
|
||||
says a new declaration field needs, and now a build and a push rather than an expedition
|
||||
([issue 142](../142-the-host-is-the-one-thing-the-mesh-does-not-deliver/01-progress.md)).
|
||||
|
||||
The host understands a `sequence` on a declaration and tolerates its absence: absent reads as "no
|
||||
order claimed", not "first", so a controller that sends none is still understood and a host that kept
|
||||
a declaration before it understood the field compares nothing. It refuses a declaration with a lower
|
||||
sequence than the one it kept, whole, and says why; and the drain that picks one declaration from a
|
||||
batch keeps the highest sequence rather than the last to arrive — which is the case the report
|
||||
constructed, a backlog drained out of order.
|
||||
|
||||
The controller numbers each send: the next number for that node, taken under the node's hold, before
|
||||
the body exists, so the number is inside what the mesh signs and a replayed older declaration cannot
|
||||
borrow a newer one's.
|
||||
|
||||
## Measured
|
||||
|
||||
```
|
||||
push shanks; push shanks

||||

||||

|
||||
g14 (none)
|
||||
status: nobody "not running what the mesh would send them"
|
||||
```
|
||||
|
||||
Both applies went through; neither was refused; the machine holding the earlier one accepted the later.
|
||||
|
||||
## The subtlety, which would have read every machine as behind for ever
|
||||
|
||||
The mesh decides a machine is behind by comparing the digest of what it **would** send against what it
|
||||
**did** send. A number changes the bytes. So the read-only comparison composes with the number the
|
||||
machine was *last* sent — not a fresh one — and is byte for byte what was sent when nothing else
|
||||
changed. Without that, numbering would have made `status` name all four machines as out of date on
|
||||
every reading, permanently.
|
||||
|
||||
## The open questions
|
||||
|
||||
- *A per-node `sequence` under the controller's node hold?* Yes, as described. **`supersedes` — the
|
||||
previous digest — is not added.** A strictly-greater sequence gives the ordering; a chain of digests
|
||||
would give continuity, which nothing here needs yet and which every re-composition would break.
|
||||
- *Genesis signing its bundle as sequence zero?* Zero is "no order claimed", which is what the bundle
|
||||
carries by carrying nothing. Same rule, no genesis branch.
|
||||
- *A marker for a mode change?* Not needed for the incident it guards: a replayed converged declaration
|
||||
reaching a node returned to adopted is already refused **by mode**, before this check runs.
|
||||
|
||||
## How it is checked
|
||||
|
||||
Host: an older sequence is refused, a newer or equal one is not, and no order claimed on either side
|
||||
compares nothing; the drain keeps the highest sequence, and falls back to arrival when none is claimed.
|
||||
Controller: a send carries its number inside the signed bytes, an unnumbered send is byte for byte what
|
||||
it was before, and each node's counter is one higher per send and readable for the comparison.

*2026-09-30. Measured on the three converged machines; the adopted one holds its resolver module until it
|
||||
is taken and is not covered.*
|
||||
|
||||
## What was actually wrong
|
||||
|
||||
Not what the report predicted. The report named the filter: a container on the runtime's default
|
||||
network asks from a bridge address, and the converged filter admitted queries by source address only.
|
||||
That was true when it was written and was fixed before this issue was ever tested — the filter admits
|
||||
by the link a packet arrives on ([ADR 0144](../../02-DECISIONS/0144-anything-on-a-machine-may-call-anything-on-it.md)),
|
||||
and a container's bridge is admitted whole. Tested on every machine: the query arrives, the filter
|
||||
passes it.
|
||||
|
||||
Three other things were wrong, each hiding the next.
|
||||
|
||||
**The runtime had never been told.** The resolver module writes the runtime's `dns` key into the
|
||||
runtime's own configuration file. The runtime reads that key when it starts and not on a reload, and on
|
||||
two machines the runtime predated the file — so every container they started got a public resolver, and
|
||||
`novox.internal` came back as not existing. Nothing reported this: the file was present and current,
|
||||
the resolver ran, and a name not existing is a valid answer. Fixed in mesh-catalog PR 175: the module
|
||||
also sets `live-restore` and reloads the runtime when its file changes, so the one restart the `dns` key
|
||||
needs no longer stops every container. The restart is then the operator's, once per machine; done on
|
||||
both today, with every running container kept.
|
||||
|
||||
**The resolver dropped the query.** With the runtime corrected, a container's query reached the resolver
|
||||
— and got no answer, on every machine, including the one whose runtime had been right all along. The
|
||||
socket was bound to the private address; the filter admitted the packet; dnsmasq received it and
|
||||
discarded it without a line of log. Its configuration said `interface=mesh0`, and dnsmasq admits a
|
||||
query by the interface it arrives on when told an interface: a container's query is addressed to the
|
||||
private address but arrives on the runtime's bridge, and the bridge is not `mesh0`. Fixed in mesh-catalog
|
||||
PR 176: the resolver is told the address to answer on, not the interface that carries it, and a query to
|
||||
that address is admitted whatever bridge brings it. The bridges are the runtime's to name.
|
||||
|
||||
**The report's second half was wrong.** "Two of four machines bind the resolver to loopback only" was
|
||||
an inference from the containers' behaviour, and the behaviour had the cause above. The resolver bound
|
||||
the private address on all four; nothing had asked it there.
|
||||
|
||||
## What is verified
|
||||
|
||||
From a container on the runtime's default network, started by hand and given nothing, on each of the
|
||||
three converged machines: `novox.internal` answers with the hub's private address, through the machine's
|
||||
own resolver. That is the fourth check of
|
||||
[ADR 0148](../../02-DECISIONS/0148-the-meshs-names-are-resolved-not-copied-into-containers.md) — "on every
|
||||
network the runtime offers" — and its first step; the record's step 2 (the runtime told per machine, as
|
||||
a file) was already how the module works. Step 3 may now begin.
|
||||
|
||||
## What checks it
|
||||
|
||||
By hand, today. Nothing in the mesh asserts that a container can resolve a mesh name: the resolver's
|
||||
own tests cover what it answers, not who can ask. The check that would have caught all three faults is
|
||||
the one the report asked for and 0148 lists — a container on the default network resolving a mesh name
|
||||
— and it is not built. It belongs with the reachability check of
|
||||
[issue 145](../145-a-machine-reads-healthy-while-its-modules-cannot-reach-each-other/00-report.md),
|
||||
which is parked; until then this is a thing a person verifies after touching the resolver, the filter,
|
||||
or the runtime's configuration.
|
||||
|
||||
## What this cost to find
|
||||
|
||||
The three faults produced one symptom — a container that cannot resolve — and each fix revealed the
|
||||
next. The first was found by reading the runtime's own view of its configuration rather than the file;
|
||||
the second by capturing the query on the bridge and finding it arrive and go unanswered; the third only
|
||||
by admitting the first belief was wrong. A machine that had been believed to work all day had never
|
||||
worked either.

**A definition no longer decides where its own data lives.** Twenty-eight definitions that named their
|

data directories now place them: the module's root as `place: "."`, a sub-directory by its id, and every
|
||||
host-side reference — bindings, secrets, own secrets, grants, receives, file paths, mounts, env-files —
|
||||
as `${dir:<id>}`. Twenty-eight others had already been written that way. Five directories whose id is
|
||||
not their last segment keep their path as a placement, which is the exception the design allows and
|
||||
the reason nothing else has to move for them.
|
||||
|
||||
**Nothing moved, and a test says so.** The controller's `TestPlacedDirectoriesKeepTheirPaths` takes the
|
||||
catalogue before and after, resolves every converted definition on the default root with the
|
||||
controller's own rule, and compares it whole with the definition before it: identical for all

twenty-eight. So the retirement this record said was a data migration turned out not to be one, on

one condition — a node's default root is where the data already is, and every node's is — and the
|
||||
machines see no change. A node that sets another root is the case this does not cover, and it does
|
||||
not exist.
|
||||
|
||||
**What remains is not this record's.** The 232 host paths still in the catalogue are where the mesh

The last delivery was unattended on all four: the fixed host was built, pushed, each machine stood
|
||||
aside exactly once for the genuinely newer version, and the delivered launcher started it — no
|
||||
restart by hand. A following push that delivered nothing new was applied and reported by every
|
||||
machine and stood nobody aside, which is the check
|
||||
[issue 163](../163-a-delivered-host-stood-aside-on-every-push-and-reported-nothing/00-report.md) asks
|
||||
for.
|
||||
|
||||
**Two more faults on the way, both mine, both found by reading the machine rather than the success
|
||||
line.** A delivered host compared the newest delivered version against its link-time stamp rather
|
||||
than the version it was running, so it stood aside on every push and — because standing aside cancels
|
||||
the report — never reported again (163). And the adopted machine kept its found launcher as the
|
||||
adoption rule says, so the delivery there needed a `take` before the launcher moved.
|
||||
|
||||
**The crossover needs one restart of the unit per machine, once.** The launcher process that was
|
||||
running on each machine was the old script, executing from its own inode; a new file beside it
|
||||
changes nothing until the unit restarts. Every subsequent delivery is unattended.
|
||||
|
||||
**Timing, measured:** on a machine, hearing a declaration to reporting it applied is about three
|
||||
seconds. A push as the operator sees it takes 17–20 seconds, and the difference is the control plane
|
||||
composing the declaration before it sends. A `--wait` shorter than that reads as "did not report" for
|
||||
a machine that did; the three-minute default read as slowness for a machine that never would. Neither
|
||||
number is a defect being chased here, and both are worth knowing before reading a push's answer.

||||
|
||||
## What this leaves

|

**the console is a module.** `mesh-console` is assigned to the machine a person sits at, holds a

mesh's tools on that machine's loopback to an agent over MCP and to a person through the same endpoint.

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 operator's data is, by the access's id. Both are validated the way `endpoints` is: an id the

definition does not declare is refused, naming what it does declare; a relative path and a

non-numeric owner are refused; an access nothing places and whose definition carries no path is
|

refused with the setting to write, rather than mounted as nothing. A placed directory is still the

mesh's — created, owned as said, removed when empty and undeclared. A placed access is still the
|
||||
operator's — mounted, never created, owned or removed.
|
||||
|
||||
An access now has an **id**, and the definition's mounts name it as `${access:<id>}`, so a placement
|
||||
moves the mount with it. Ten catalogue definitions were given ids; each keeps its path as the default
|
||||
an assignment may replace, so the machine that said nothing received exactly the paths it had before
|
||||
(the path-preservation proof, extended to accesses). That default is still a host path in a

definition, tolerated as the transition: the media modules on the control node hold it until their

assignments say where the data is, and then the defaults go.

What the home server's assignments say next is the operator's: per media module, `places` for the

## Why
|
||||
|
||||
After an apply the host asks whether a newer host has been delivered than the one running, and the
|
||||
question was asked with the **link-time version stamp**. Since
|
||||
[issue 161](../161-a-delivered-host-carries-none-of-its-link-time-facts/01-resolution.md) a delivered
|
||||
host's version comes from where it sits and its stamp is `development build` — so the comparison never
|
||||
matched the newest delivered version, and "a newer host is waiting" was always true.
|
||||
|
||||
Standing aside cancels the context the report is published with, so the report was lost on every one
|
||||
of those applies. Two faults from one wrong argument.
|
||||
|
||||
The change that moved the version to the path was applied to the report and to the known-good record,
|
||||
and not here. Half a change, and the half left behind was the one that decides whether to exit.
|
||||
|
||||
## Why the three-minute wait made it invisible
|
||||
|
||||
The push's `--wait` timing out read as *slow*. It was not slow: **the report was never going to arrive.**
|
||||
The operator put it exactly: *if you don't get a response in five seconds, something is wrong.* A wait
|
||||
long enough to absorb a machine's whole apply is a wait long enough to hide that the machine never
|
||||
answered.
|
||||
|
||||
## How it is checked
|
||||
|
||||
A machine running a delivered host is pushed a declaration that delivers nothing new; it applies,
|
||||
reports, and does not stand aside. A machine running a delivered host is pushed a genuinely newer
|
||||
version; it stands aside once, and the next push it does not.

# 164 — A credential that must be accepted is minted anyway
|
||||
|
||||
## What was observed
|
||||
|
||||
Provisioning ace's modules. Several providers hold exactly one credential they did not get from the
|
||||
mesh and cannot take one from it: a Servarr app's API key (sonarr, radarr, lidarr), jackett's API key,
|
||||
plex's X-Plex-Token, nzbget's ControlPassword, qBittorrent's WebUI password. Their consumers' pair
|
||||
credential must be **accepted** by the operator (ADR 0092). Until it is, `SecretFor` mints a random
|
||||
value, seals it to both ends, and reports nothing: the value can never work.
|
||||
|
||||
Every consumer therefore had to learn to detect it — try the credential against the provider first,
|
||||
refuse a value the provider rejects, print the `secret accept` command — six write-in steps, one probe
|
||||
each (ombi, home-assistant, and the four download-stack consumers). qBittorrent bans an address after
|
||||
five failed logins, so a consumer retrying a minted value locks itself out.
|
||||
|
||||
## What would be right
|
||||
|
||||
A provision (or a provider's `serves`) can declare its pair credential **accepted-only**. The plan then
|
||||
refuses the pair — naming the accept command — instead of minting, and a consumer is never handed a
|
||||
value the mesh knows cannot work.

# 165 — One accepted value must be accepted once per consumer
|
||||
|
||||
## What was observed
|
||||
|
||||
On ace, jackett's API key is the pair credential for sonarr, radarr, lidarr and bookshelf; sonarr's is
|
||||
the credential for ombi, bazarr and home-assistant. It is **one value**, owned by the provider — yet
|
||||
`secret accept` is per pair, so ace's download stack alone needs 12 accepts of 3 values, and rotating
|
||||
a provider's key means finding and re-accepting every pair. Missing one leaves that consumer on a
|
||||
stale (or minted, 164) value.
|
||||
|
||||
## What would be right
|
||||
|
||||
A provider-level accept: "this provider's credential for `<provision>` is X" — delivered to every
|
||||
consumer pair, current and future, and rotated in one place. Pairs whose credential is genuinely per
|
||||
consumer (postgres, keycloak, mosquitto, influxdb — minted and created by a provisioner) are unaffected.

# 166 — A requirement cannot be optional
|
||||
|
||||
## What was observed
|
||||
|
||||
Making every dependency on ace a provision turned soft dependencies into hard ones. grafana now
|
||||
requires `influxdb-api` (a data source), ombi requires `sonarr-api`, `radarr-api` and `lidarr-api`,
|
||||
home-assistant requires the Servarr APIs and `mqtt-topic`. Each is optional to the software — grafana
|
||||
runs without a data source, ombi without lidarr — but a mesh without influxdb cannot assign grafana at
|
||||
all, and a mesh without lidarr cannot run ombi.
|
||||
|
||||
## What would be right
|
||||
|
||||
A requirement a module can run without: resolved and bound when a provider exists, absent (with its
|
||||
`${bound:…}` placeholders refused or defaulted explicitly, never rendered empty) when none does — so
|
||||
the module description stays true on every mesh.

# 167 — Code several modules share has no home
|

|
||||
## What was observed
|
||||
|
||||
The download-stack write-in step (register download clients and torznab indexers through the Servarr
|
||||
API) is identical for sonarr, radarr, lidarr and bookshelf. Because a module builds from its own
|
||||
directory, it now exists as four byte-identical copies under `modules/<m>/downloads/`, kept honest by a
|

test that fails when one differs. The same shape repeats: an MQTT probe copied into two modules, and a

"write the provider into the app through its API, idempotently, refuse a minted value" step in ombi,

home-assistant, nodered, tautulli and the four downloaders.

# 168 — A setting reaches every file and every contribution
|
||||
|
||||
## What was observed
|
||||
|
||||
Settings merge key by key into **every** `"merge": "json"` file of a module **and** every contribution
|
||||
it makes; a provider's settings are also laid over what it serves. Seen on ace:
|
||||
|
||||
- searxng's `endpoints` and a route `label` land in searxng's own `settings.yml`; nodered's
|
||||
`timeZone` and `mqtt` keys land in mosquitto's grants file; keycloak's `issuer` lands in its
|
||||
`postgres-database` and `route` contributions.
|
||||
- every consumer's `plex-api` binding carries plex's `endpoints` and `expose` settings — and a provider
|
||||
setting named `port` would silently redirect every consumer.
|
||||
- a module cannot have two configurable files: searxng's sidecar config had to stop being mergeable
|
||||
so searxng's keys would not reach it.
|
||||
|
||||
Harmless today only because every receiver happens to ignore unknown keys.
|
||||
|
||||
## What would be right
|
||||
|
||||
A setting is aimed: at a file (by resource id), at a contribution (by requirement), or at what the
|
||||
module serves — declared settable by the module (ADR 0046 already says settings drive "the fields the
|
||||
manifest marks") — and an unaimed key is refused like any unknown setting.

# 171 — A module that names its own resolver knows no mesh name
|
||||
|
||||
## What was observed
|
||||
|
||||
The afternoon [ADR 0148](../../02-DECISIONS/0148-the-meshs-names-are-resolved-not-copied-into-containers.md)
|
||||
landed — no container is given the mesh's names any more; it asks the machine's resolver — the mail
|
||||
system's admin container began logging, 523 times in three minutes:
|
||||
|
||||
```
|
||||
psycopg2.OperationalError: could not translate host name "novox.internal" to address: Name does not resolve
|
||||
```
|
||||
|
||||
Mail was accepted on every port and the web front answered; the admin and the spam filter beside it
|
||||
were unhealthy, and anything that needed the database — a mailbox change through the API, the spam
|
||||
filter's domain list — failed. Found by the operator asking whether mail was back, forty minutes in.
|
||||
|
||||
Mailu ships its own resolver, an unbound in a container, and every other Mailu container is told to
|
||||
use it — the module carries `dns: [192.168.203.254]` on eight containers. That resolver recurses from the
|
||||
root and knows nothing under `.internal`. Until that afternoon the admin container had the database's
|
||||
name anyway, because the mesh wrote every name into every container at creation; the copy was the only
|
||||
reason a container behind its own resolver could reach anything by a mesh name, and nobody knew it was
|
||||
load-bearing.
|
||||
|
||||
**Removing the override was not enough.** Given the machine's resolver instead, the admin refused to
|
||||
start: `Your DNS resolver at 127.0.0.11 isn't doing DNSSEC validation`. Mailu checks, at start, that
|
||||
its resolver returns the Authenticated Data bit for a signed name. The mesh's resolver forwards to two
|
||||
upstreams that validate and set the bit, and dropped it on the way down — dnsmasq does unless told
|
||||
otherwise. Mailu's own unbound has no hook to forward a zone elsewhere, so it could not be taught the
|
||||
mesh's names either.
|
||||
|
||||
## Why it matters beyond this instance
|
||||
|
||||
**A container with a resolver of its own has opted out of the machine's, and nothing says so.** 0148
|
||||
made the machine's resolver load-bearing for every container; a `dns` on a container is a quiet
|
||||
exception to that, and the exception used to be papered over by the copy the record removed. The
|
||||
manifest field reads like a preference and is a decision about whether mesh names exist inside the
|
||||
container.
|
||||
|
||||
**A resolver that forwards to validating upstreams and hides the fact is less useful than it could
|
||||
be**, and the first program to check found out.
|
||||
|
||||
**The mesh reported nothing.** Every container ran; the failing one accepted connections; the report
|
||||
was about bytes. It is [issue 145](../145-a-machine-reads-healthy-while-its-modules-cannot-reach-each-other/00-report.md)
|
||||
again, and the check that would have caught it is the same unbuilt one.
|
||||
|
||||
## What was done
|
||||
|
||||
- The one Mailu container that binds a mesh name — the admin, through the database it is granted —
|
||||
no longer names Mailu's resolver and uses the machine's, like every container without a `dns` of
|
||||
its own (mesh-catalog PR 178). The other seven keep unbound: the spam filter needs a validating
|
||||
resolver for its blocklist lookups, and none of them asks for a mesh name.
|
||||
- The machine's resolver passes the DNSSEC bit down from its upstreams, `proxy-dnssec` (PR 179). It
|
||||
does not validate itself; the trust is the upstream's and the path to it, as a forwarding resolver's
|
||||
always was, and the configuration says so.
|
||||
|
||||
## What checks it
|
||||
|
||||
The admin container's own start-up check, which is what failed, and the mesh's status once it reads
|
||||
healthy. A container-level check that a mesh name resolves from inside every declared container is
|
||||
the one 110 and 145 both ask for and is not built.
|
||||
|
||||
## Open questions
|
||||
|
||||
- Should a container's `dns` be refused, or made to say what it gives up? A module that names its
|
||||
own resolver and binds a mesh name is a contradiction the controller can see at composition — the
|
||||
grant hands it a name its resolver will not answer.
|
||||
- Should the machine's resolver validate rather than proxy? It would cost a trust anchor on every
|
||||
machine and make the resolver slower to start; proxying was enough for the one program that asked.

# 172 — The ssh client block for a machine matches one spelling of its name, and the other gets the wrong user
|
||||
|
||||
## What was observed
|
||||
|
||||
On a workstation, 2026-09-30, reported by the operator. `ssh home-server` logs in; `ssh
|
||||
home-server.internal` is refused with `Permission denied (publickey)`. The operator expected the
|
||||
opposite, if either: the full mesh name is the one the resolver serves.
|
||||
|
||||
The name is not the fault. Both spellings resolve to the machine's private address — the mesh's roster
|
||||
region in the hosts file carries `<node>.internal <node>` on one line, and the resolver answers
|
||||
anything under the node's name. What differs is the login: the generated client configuration has a
|
||||
`Host home-server` block naming the account to log in as, and `home-server.internal` matches no block,
|
||||
so ssh falls back to the operator's local username, which has no account on that machine. Spelled
|
||||
`account@home-server.internal` it works.
|
||||
|
||||
The file is the predecessor's. `~/.ssh/config.d/mesh` says in its own header that it is generated by
|
||||
the predecessor's terminal module, which only ever wrote the bare name. The mesh's own ssh-client
|
||||
roster — every other machine's Host block, written as a marked region of the operator's `~/.ssh/config`
|
||||
with the account the mesh knows for that machine (to-be 29) — already matches both spellings, and a
|
||||
controller test holds `Host marge marge.internal`. It is composed and tested in the controller and is
|
||||
not a module in the catalogue, so no machine receives it; every workstation still runs the
|
||||
predecessor's generator.
|
||||
|
||||
## Why it matters beyond this instance
|
||||
|
||||
**A name the mesh serves and a name a person can use are not the same set**, and the difference is
|
||||
silent. The resolver, the hosts file and the certificate authority all treat `<node>.internal` as the
|
||||
machine's name; the one file that decides who you log in as does not know it. A person who learns the
|
||||
mesh's name from `status` or from a certificate and types it is refused with an error that says
|
||||
nothing about a missing Host block.
|
||||
|
||||
**It is the migration story for the operator's own tooling, arriving as a symptom.** The mesh has the
|
||||
right file and does not ship it. Until the ssh-client roster is a module and is assigned to the
|
||||
workstations, the predecessor's generator keeps writing a file the mesh has already superseded, and
|
||||
every such file is one the mesh cannot correct.
|
||||
|
||||
## Open questions
|
||||
|
||||
- Should the ssh-client roster become a catalogue module now, assigned to every workstation, and take
|
||||
the predecessor's `config.d/mesh` out of the operator's `Include`? Its content is settled; what is
|
||||
not is the takeover of a file in a person's home that another generator still writes.
|
||||
- Should the block match a third spelling — the machine's public name, where it has one — or is that
|
||||
a different key and a different account?
|
||||
- What checks it? A controller test holds the two spellings; nothing checks that the file a workstation
|
||||
actually has is the mesh's rather than the predecessor's.

# 173 — A module's settings reach every fact it contributes, not only the file that asked
|
||||
|
||||
## What was observed
|
||||
|
||||
Setting the mail module's operator values — `domain`, `sitename`, `website`, `proxy-address` — so that
|
||||
its environment file could read them as `${setting:…}`
|
||||
([ADR 0155](../../02-DECISIONS/0155-a-definition-names-no-installation-and-how-that-is-checked.md)),
|
||||
and then planning the control node, showed the four keys in places nothing asked for them:
|
||||
|
||||
- in every **route** the module contributes to the proxy, beside `label`, `endpoint` and `port`;
|
||||
- in the **database** it contributes to the store's provider, beside the database's `name`;
|
||||
- in the `smtp` facts every **consumer** of its mail provision is bound to.
|
||||
|
||||
Nothing broke: a provider ignores a key it does not read. But a proxy now receives a mail server's
|
||||
`proxy-address` and `website` as if they were route facts, a consumer of mail is told the site's name,
|
||||
and a reader of `plan` cannot tell which of a contribution's keys the module meant and which leaked in.
|
||||
|
||||
## Why this is here
|
||||
|
||||
Settings are one flat map per module, laid over every mergeable file, every contribution and every
|
||||
served fact alike (`settle`). That was the right generality when a setting *was* a contribution's
|
||||
override — a route's label is the example the code gives. It stops being right the day a setting is
|
||||
an operator's value for one file, which ADR 0155 made ordinary. The design permits a value to travel
|
||||
where nobody sent it, silently, and every consumer of a provision reads a map that grows with the
|
||||
provider's unrelated settings.
|
||||
|
||||
[ADR 0112](../../02-DECISIONS/0112-a-module-definition-names-no-node-mesh-or-path.md) and design 27
|
||||
already say where this ends: a requirement has a contract, and a value goes to the requirement that
|
||||
asked for it. Until that form exists, this is the cost of the placeholder being the first case of it.
|
||||
|
||||
## Open questions
|
||||
|
||||
- Should a key a file asks for with `${setting:<key>}` be withheld from contributions and served
|
||||
facts, or should a contribution's overrides live under their own key (`contributes`, `serves`)?
|
||||
The second is the shape design 27 draws; the first is the smaller change and keeps the leak from
|
||||
widening while it is drawn.
|
||||
- What does a consumer do with a served key it did not expect? Today: nothing, silently. A served
|
||||
map is not checked against what the provision's contract says it carries, because there is no such
|
||||
contract yet.
|
||||
|
||||
## Resolved, 2026-09-30
|
||||
|
||||
**A setting overrides a key a contribution or a served fact declares, and adds none.** A file keeps
|
||||
taking any key, because a configuration file is where an operator adds things; a contribution and a
|
||||
served fact are a contract the other side reads, and a setting made for one of the module's files is
|
||||
no part of it. A key that lands nowhere — no mergeable file, no `${setting:…}` asking for it, no
|
||||
contribution or served fact declaring it — is named as stray when the node is planned, rather than
|
||||
dropped.
|
||||
|
||||
The first open question is answered the smaller way, and it turned out to be the right one: the two
|
||||
keys consumers actually read through the leak — the mail provider's `domain`, the identity provider's
|
||||
`issuer` — are now **declared** by the provider in what it serves, as the operator's value
|
||||
(`${setting:domain}`, `${setting:issuer}`), filled from the same setting that used to leak and refused
|
||||
by name when nothing sets it. So the contract says what travels, which is the shape design 27 draws,
|
||||
without a second key for overrides. The second question stands: a consumer still checks nothing
|
||||
against a contract, because there is none yet; what it is told is now only what the provider
|
||||
declared.
|
||||
|
||||
*How it was checked:* the plans of all four nodes, under the running controller and the one with the
|
||||
rule, compared resource by resource — every key that disappears from a contribution is a leaked file
|
||||
setting or one of the mesh's own words (`expose`, `endpoints`), and nothing a provider reads goes
|
||||
away; the two served keys were declared before the controller rolled. Unit tests: a setting a route
|
||||
never declared does not reach the proxy; a served value nothing sets is refused by name; the setting
|
||||
a served fact asks for is not stray.

# 174 — The mesh's own files for a module are placed by the definition, not by the mesh
|
||||
|
||||
## What was observed
|
||||
|
||||
After every module's *own* data directory was placed by the mesh
|
||||
([issue 119](../119-a-module-definition-decides-where-its-files-live/00-report.md)), the catalogue
|
||||
still carries **232 host paths in 50 definitions**, all of one kind: where the mesh writes what it
|
||||
makes *for* the module — its sealed bus credential (`own-secrets.broker`), its merged config file, its
|
||||
bindings — under `/var/lib/mesh/<module>/…`, and the directory resource that creates that subtree.
|
||||
Not one of those files is the module's. The mesh mints the credential, composes the binding, merges
|
||||
the config; the definition only says where to put them, and says it the same way seventy times.
|
||||
|
||||
## Why this is here
|
||||
|
||||
Design 27's answer to *what sits beneath a node's root* (2026-09-26) is that the mesh's writes need no
|
||||
module-visible reservation: **what the mesh writes for a module is the mesh's plumbing, placed where
|
||||
the mesh chooses and mounted in, never part of the module's contract.** The definition today names
|
||||
that place, so a definition is not yet free of host paths — and a node whose root is elsewhere would
|
||||
place the module's data there and the mesh's files still under `/var/lib/mesh`.
|
||||
|
||||
The path-preserving test that let issue 119 close does not cover this: it proves a *placed* directory
|
||||
resolves to what was named, and these are not placed.
|
||||
|
||||
## What it would take
|
||||
|
||||
A word for "the mesh's file for this module", or none: `own-secrets` values, a merged config file and
|
||||
a binding could be named by key alone, with the mesh choosing `<root>/mesh/<module>/<key>` and
|
||||
mounting it where the container says. The container side of the mount already exists in every
|
||||
definition (`/run/secrets/broker`, `/run/config/config.json`); only the host side would go. The
|
||||
change is in the controller, once, and then a mechanical edit of fifty definitions, which the same
|
||||
test that proved 119 can prove again with the rule extended.
|
||||
|
||||
## Open questions
|
||||
|
||||
- Does `own-secrets` keep its map shape with the value becoming the *container* path rather than the
|
||||
host path, or does the mount stay where it is and the host side become a placeholder the mesh
|
||||
fills, `${mesh:<key>}`?
|
||||
- A binding file today lands wherever `binds` says; a module's code reads it from an environment
|
||||
variable naming the container path. If the host side is the mesh's, is the container side still the
|
||||
definition's to choose? It should be: it is the software's contract.
|
||||
|
||||
## Resolved, 2026-09-30
|
||||
|
||||
The word is the one issue 119 introduced, with a second place: a directory saying `place: "mesh"` is
|
||||
the mesh's directory for the module, `<root>/mesh/<module>`, beside the assignment's own root and
|
||||
under the same node setting. The mesh's files keep their map shape and the container side of every
|
||||
mount stays the definition's — only the host side changed, to `${dir:mesh-state}/…`. A directory that
|
||||
sat beneath the mesh's (a forge's runtime state, a manager's output) states its path as
|
||||
`${dir:mesh-state}/<rest>` and moves with it; one that sits elsewhere by adoption (the registry's data)
|
||||
keeps its literal path as the exception it is.
|
||||
|
||||
Forty-eight catalogue definitions and the controller's own manifest were converted mechanically. The
|
||||
proof is the same test that let issue 119 close, now resolving *both* checkouts before comparing,
|
||||
because the earlier manifest already placed its own directories: resolved on the default root, every
|
||||
converted definition names exactly the paths it named before. Nothing moved.
|
||||
|
||||
Both open questions are answered by keeping what exists: the map stays, the host side is placed; the
|
||||
container side is the software's contract and stays where the definition says.

# 175 — An announcement queued behind a long build comes back, and the build runs again
|
||||
|
||||
## What was observed
|
||||
|
||||
On the evening of 2026-09-30 five merges landed within minutes. The controller's log then showed the
|
||||
same four announcements — two into this repository, one into the catalogue, one into the controller's
|
||||
own — arriving again every couple of minutes, and each arrival of the controller's rebuilt the two
|
||||
modules that package its source. The builder built `builder` and `route-proxy` five times over for one
|
||||
merge, the control node was pushed after each, and every other message the controller handles waited
|
||||
behind the builds. It looked like a slow mesh; it was a loop.
|
||||
|
||||
Earlier the same evening, at a lower rate, the log already carried duplicated lines — a merge seen
|
||||
twice, a module "moved" twice — that nobody read as a symptom.
|
||||
|
||||
## Why
|
||||
|
||||
The controller acts on what it consumes in **one loop, one message at a time**, and a merge's handler
|
||||
builds every module the merge changed before it returns — minutes of work. The bus's acknowledgement
|
||||
window is thirty seconds. That contradiction was met once already: the message being worked on is kept
|
||||
alive by a heartbeat while its handler runs
|
||||
([issue 127](../127-a-module-event-derives-a-subject-nothing-publishes/00-report.md)'s stretch,
|
||||
controller PR 122). **The heartbeat covers one message.** The consumer is a push consumer with no
|
||||
bound on what it may have outstanding, so the client is handed everything that is waiting at once; the
|
||||
messages queued behind the one being built time out unacknowledged, come back after thirty seconds,
|
||||
and are handled again when the loop gets to them — including the merge whose builds are already done,
|
||||
which builds them again. A module that only *packages* another repository's source has no record of
|
||||
which commit it was last rebuilt for, so nothing says "already done".
|
||||
|
||||
## Why it matters beyond this instance
|
||||
|
||||
The design permits work to be done twice, silently, and the doubling scales with how busy the mesh
|
||||
is: the busier the builder, the longer the queue, the more that comes back. A push to a machine is
|
||||
idempotent and a rebuild produces the same digest, so nothing broke — but every merge cost several
|
||||
builds, the control node was pushed after each, and a person watching saw a mesh that would not
|
||||
settle. It was the redelivery storm of 2026-09-28 in a narrower form, one layer out.
|
||||
|
||||
## What would have prevented it
|
||||
|
||||
- **A consumer that is handled one at a time is delivered one at a time.** `MaxAckPending: 1` on the
|
||||
controller's events consumer: the server holds the rest, nothing times out behind a build, and the
|
||||
heartbeat that keeps one message alive is then keeping *the* message alive.
|
||||
- **A packaging module records the commit it was last rebuilt for**, so a replayed announcement is
|
||||
"already built from it", the answer the source-built modules already give.
|
||||
- **A log line that appears twice with the same commit is a symptom**, and the check is cheap: the
|
||||
same announcement acted on twice within its window is a count worth exposing in `status`.
|
||||
|
||||
## Resolved on the first remedy, 2026-09-30
|
||||
|
||||
`MaxAckPending: 1` on the controller's events consumer (mesh-controller PR 173): the server hands the
|
||||
controller one announcement at a time and holds the rest, so nothing times out behind a build. The
|
||||
existing consumer is brought to that configuration by the assertion the controller makes at start.
|
||||
The second and third remedies — a packaging module recording the commit it was last rebuilt for, and
|
||||
a doubled announcement counted in `status` — are not built; they would make the same fault visible
|
||||
and cheaper should the first ever be undone, and they are left here as what to reach for then.

# 176 — The console's `build` tool neither waits nor registers, and does not take a forge path
|
||||
|
||||
## What was observed
|
||||
|
||||
Eight media modules held by the mesh had not been rebuilt after their manifests changed, because a
|
||||
merge rebuilds only the modules whose recorded source is the merged repository and theirs was another
|
||||
one. Asked through the console — the controller's `build` tool, served on its seat
|
||||
([ADR 0154](../../02-DECISIONS/0154-the-meshs-own-verbs-are-the-controller-seats-tools.md)) —
|
||||
with the repository given as its path on the forge, the way the tool's own description invites:
|
||||
|
||||
- every call answered at once with *no build machine answered within 0s … the work is queued*;
|
||||
- the builder, asked in the same breath, failed each one with *cannot clone novox/mesh-catalog*: the
|
||||
path was handed to `git clone` as written, because the tool never says the repository is a path on
|
||||
the forge holding the git seat (`--self`), which the command line requires for that form;
|
||||
- given the repository's URL instead, the call still answered within zero seconds, the build ran on
|
||||
the builder, its result was heard and recorded — and the module was **not registered**: what hears a
|
||||
finished build records the build and stops; only the caller that waited would have parsed the
|
||||
manifest and registered it, and the caller had gone.
|
||||
|
||||
So the console can start a build and never learn its outcome, and a build it starts cannot change
|
||||
what the mesh holds. The tool's description — *have the build machine build a repository and record
|
||||
what came out* — is true of the build record and false of the module.
|
||||
|
||||
## Why this is here
|
||||
|
||||
The seat verb was written as fire-and-forget, deliberately (`--wait 0`), so that a tool call over the
|
||||
bus does not sit for the minutes a build takes. That reasoning moved the wait but not the work that
|
||||
followed it: registration lives in the waiting caller, not in the path that hears the result. The two
|
||||
halves of "build" — asking, and taking in what came back — are split across the command and the
|
||||
event handler, and the tool reaches only the first.
|
||||
|
||||
The forge-path form is a second, smaller gap: the seat verb maps three arguments and forgets the flag
|
||||
the same command needs to read one of them.
|
||||
|
||||
## What would be right
|
||||
|
||||
Registration belongs where the result is heard, once, so a build's outcome reaches the mesh whoever
|
||||
asked and whether or not they waited — the same rule as an announcement's builds. The tool then
|
||||
answers with what it can say at once (asked, queued, or refused) and `builds` says the rest. A
|
||||
repository given without a scheme is a path on the git seat, and the verb says so.
|
||||
|
||||
## Open questions
|
||||
|
||||
- Should a tool call be able to wait at all? A builder answers in minutes; the console's transport
|
||||
holds a call for a bounded time. If not, the tool needs a way to follow one build — which is the
|
||||
builder's missing progress (no tools, no events) named in the console's review of 2026-10-01.
|
||||
|
||||
## Resolved, 2026-10-01
|
||||
|
||||
Registration moved to where the outcome is heard. One function takes a build's outcome in — records
|
||||
the build, parses the manifest, refuses a definition that names an installation, registers the module
|
||||
with its source as the seat and path the request carried and the outcome echoes — and both the
|
||||
command that waited and the daemon that follows the role's `built` event call it. So a build asked
|
||||
for by anything that could not wait reaches the catalogue the same as one asked for by hand, and the
|
||||
same outcome heard twice writes one row twice with the same values.
|
||||
|
||||
The tool keeps not waiting, and says so: `build --wait 0` publishes the work and answers with the
|
||||
build's id, and `builds --log <id>` follows the build line by line ([ADR 0157](../../02-DECISIONS/0157-a-build-says-what-it-does-on-the-bus-as-it-happens.md)),
|
||||
which is what a tool call over the bus can do in the seconds it has. A repository given without a
|
||||
scheme is said to be a path on the git seat, so the forge-path form the tool's description invites
|
||||
now works.
|
||||
|
||||
The open question is answered by the shape: a tool call does not wait; it asks, gets the id, and
|
||||
follows. *How it is checked:* the shared take-in against a raised store — registered with the seat
|
||||
source, a definition naming an installation recorded and refused, a failure said in the builder's
|
||||
words — and the tool's mapping of a forge path against a URL.

# 177 — The controller's check is run by nobody, and two of its tests failed for days unseen
|
||||
|
||||
## What was observed
|
||||
|
||||
`make check` on the controller's main failed two store-backed tests on 2026-10-01, both for
|
||||
reasons older than that day:
|
||||
|
||||
- the guard that holds a converged declaration byte for byte to what an older host was sent still
|
||||
expected a `hosts` list on every container, after the change of 2026-09-30 that took it off — a
|
||||
machine's own resolver knows the mesh's names now ([issue 171](../171-a-modules-own-resolver-knows-no-mesh-name/00-report.md));
|
||||
- the adopted machine in the converge test reported no outward link, after
|
||||
[ADR 0140](../../02-DECISIONS/0140-the-filter-constrains-what-arrives-from-outside.md) (2026-09-28)
|
||||
made a filter depend on one.
|
||||
|
||||
Neither commit touched the test it broke, and neither merge failed: the mesh builds the controller
|
||||
from its repository and runs none of its tests. The tests that need a store — the ones that say what
|
||||
a machine is actually sent — are exactly the ones a quick `go test ./...` skips, so a person running
|
||||
the fast check sees green too. Every merge tonight, this one included, was checked that way.
|
||||
|
||||
## Why this is here
|
||||
|
||||
A guard that is not run is a comment. The byte-for-byte guard exists because an older host parses a
|
||||
declaration strictly and a field it does not know is a machine that applies nothing
|
||||
([ADR 0100](../../02-DECISIONS/0100-a-node-in-use-is-adopted-before-it-is-converged.md)); it went
|
||||
red on a change that happened to be safe — a field removed — and would have gone red the same way on
|
||||
one that was not. The mesh has a rule that a test defends a decision
|
||||
([ADR 0017](../../02-DECISIONS/0017-a-test-defends-a-decision.md)) and no rule that says when the
|
||||
test is run.
|
||||
|
||||
## Resolved, 2026-10-01 — the tests
|
||||
|
||||
The guard is re-captured with the change named in its own comment: a field an older host never sees
|
||||
is the one change the guard permits, a field it would refuse is the one it exists to catch. The
|
||||
fixture reports an outward link as a real host does. `make check` is fully green on main again
|
||||
(mesh-controller PR 180). No code changed.
|
||||
|
||||
## Open — the process
|
||||
|
||||
The build should run the check, or something should, before a merge lands. What that is — the
|
||||
builder raising the store the tests need, a check the forge runs on a pull request, or the controller
|
||||
refusing to record a build whose repository's own check fails — is a decision not taken here. Until
|
||||
it is, `make check` before a controller merge is the operator's habit, written into the work order,

||||
and this issue stays the record of why.
