# 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 |

|

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
|
## The record
|
||||||
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.
|
|
||||||

|
||||||
Its content is overwhelmingly the record of previous debugging: a large body of

|
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
|
It is listed by the console beside every other tool, with a description that says to search the

|
||||||
|
|
||||||
## The structured archive
|
Nothing is copied. A checkout lags the source by seconds after an announced merge and by minutes
|
||||||
|
otherwise, and says so.

|
||||||
lifecycle.
|
|
||||||

|
||||||
Content is promoted through tiers — private, then team, then platform — with a librarian agent
|
[`00-META/how-we-build.md`](../../00-META/how-we-build.md) is the source of the mesh constitution
|
||||||
owning approval and promotion at the boundary. Proposals to edit are reviewed rather than
|
([ADR 0021](../../02-DECISIONS/0021-hq-is-the-source-of-the-constitution.md)). The page it used to be
|
||||||
applied.
|
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.
|
||||||
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.

|
||||||
|
|
||||||
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

## A seat's protocol is on its row, and the controller serves its own
|
||||||
|
|
||||||
|
*Since 2026-09-30 ([ADR 0154](../../02-DECISIONS/0154-the-meshs-own-verbs-are-the-controller-seats-tools.md)).*
|
||||||
|
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
|
||||||
|
name. A node-scoped seat's tool is `mesh.seat.<seat>.tool.<verb>.<node>`; no node-scoped seat declares
|
||||||
|
one yet.

*2026-10-01 — [ADR 0157](../../02-DECISIONS/0157-a-build-says-what-it-does-on-the-bus-as-it-happens.md).*
|
||||||
|
|
||||||
|
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. A viewer of builds, when one is built, is a subscriber over these subjects and the outcome; the
|
||||||
|
builder needs nothing more for it.
|
||||||
|
|
||||||
|
*How it is checked:* the holder's grant is exactly `started`, `built` and `log.*` (broker test); a
|
||||||
|
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.

|
Under [ADR 0154](../../02-DECISIONS/0154-the-meshs-own-verbs-are-the-controller-seats-tools.md): §2's
|
||||||
|
two constraints (the protocol in the store's row, seeded additively; a verb with description and
|
||||||
|
schema, a bare name still accepted), §3 for the mesh's seats (holding refused by naming the missing
|
||||||
|
verbs), §4 (a node-scoped seat's tool carries the node as its last subject token; a user publishes
|
||||||
|
`*`), and the third family — twelve verbs on the `mesh-controller` seat, each running the command it
|
||||||
|
names in the controller's own binary. §5's first half is served rather than read: the seat's `tools`
|
||||||
|
verb answers every seat's tools from the records, because the console cannot read the store; the
|
||||||
|
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
|
||||||
|
parsed from standard output alone (mesh-controller PR 168, pending). The `output` field carried it
|
||||||
|
either way.
|
||||||
|
|
||||||
|
What stays as designed and not built: which verbs any *other* seat serves, and §3 for module-declared
|
||||||
|
seats' schemas beyond the names their manifests already list.

# 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.

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.
|

Open beside it, and not this record's: the mesh has no symptom-indexed memory at all since the

|
cut-over ([as-is 07](../../03-DESIGN/00-as-is/07-knowledge.md) says so), and the lessons of these

|
||||||
|
|
||||||
|
**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
|
||||||
|
writes what it makes for a module, under `/var/lib/mesh/<module>`; design 27 says the mesh places
|
||||||
|
those itself, and it does not yet. That is [issue 174](../174-the-meshs-own-files-for-a-module-are-placed-by-the-definition/00-report.md). *Placed since later the same day: `place: "mesh"` — issue 174 is resolved.*
|
||||||
|
The defects this record listed under *where that has already gone wrong* are unchanged by this and
|
||||||
|
stay in 174's scope where they concern the mesh's files; the operator's shared data stays an access
|
||||||
|
([ADR 0051](../../02-DECISIONS/0051-shared-data-is-the-operators.md)).
|
||||||
|
|
||||||
|
The manifest change lands with the catalogue's next merge; the rollout is a rebuild that changes no
|
||||||
|
machine, checked by comparing each machine's plan before and after.

The open questions, answered in order. **A module names what it will be reached at** through the
|
||||||
|
binding of the route it contributes: `${bound:route:name}`, or `:name-<local>` for several
|
||||||
|
contributions, is the composed public name; `:internal-name` the private one (controller PR 149). The
|
||||||
|
identity provider, the object store's console and the automation tool's webhook now read it there.
|
||||||
|
**The scheme is the module's**, because it is true of the route the proxy terminates and every instance
|
||||||
|
wrote `https://` in front of the name. **An adopted resource's name is a setting** on the assignment;
|
||||||
|
so is every other operator's value — a mail domain, a site name, the address a proxy forwards from —
|
||||||
|
as `${setting:<key>}` in the file the software reads
|
||||||
|
([ADR 0155](../../02-DECISIONS/0155-a-definition-names-no-installation-and-how-that-is-checked.md)).
|
||||||
|
**The check that notices the next one** is the shape of the value, as this record guessed it would be,
|
||||||
|
and it is more than nothing: it found forty-two, and the catalogue passes it now
|
||||||
|
([issue 134](../134-a-definition-may-still-name-the-mesh/00-report.md)).
|
||||||
|
|
||||||
|
**What the rollout cost, 2026-09-30 evening.** The site module's rename from its domain to `website`
|
||||||
|
was a new module to the mesh, and two things the old assignment carried by name were lost: the
|
||||||
|
container still named the old network, and a port setting on the old assignment had hidden that
|
||||||
|
`listens` said one port while the container published another. The site answered 502 for about
|
||||||
|
twenty minutes across two one-line fixes (mesh-catalog PRs 190, 191). A module's rename is an
|
||||||
|
unassign and an assign, and everything the assignment held — settings, ports, its directory — is the
|
||||||
|
new module's to get again; the mesh says nothing about that today. The mail module's settings turned
|
||||||
|
out to reach every fact it contributes, which is [issue 173](../173-a-modules-settings-reach-every-fact-it-contributes/00-report.md).

The two assignment halves ADR 0112 decided exist. On an assignment's settings, `places` puts a
|
||||||
|
declared directory (by id) at a path on this node, with an owner where the data already has one —
|
||||||
|
`{"config": "/where/it/is", "data": {"path": "…", "owner": "1001:2000"}}` — and `accesses` says where
|
||||||
|
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
|
||||||
|
configuration on the second disk and `accesses` for the pool, with the owner the predecessor ran as.

# 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.

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.
