 # 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.

 [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.

 | 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 |

 # 158. A provider with one credential shares it with every consumer, and the vault remakes it for all of them at once
 ## Context
 [ADR 0048](0048-a-provider-creates-the-credential-the-mesh-minted.md) gave every consumer of a
 provision its own credential: the mesh mints one per pair, the provider's own code creates the
 login, and rotating one consumer's touches nothing else. That is right for a database, a broker, an
 object store — software that can hold many logins.
 The media software on the home server cannot. A download client has one web password; an indexer
 has one API key; each of the library managers has one key in its configuration; the media server
 holds one token issued elsewhere. There is no login per consumer to create, so
 [ADR 0113](0113-the-vault-makes-every-secret.md)'s only remaining form applied: the value is
 *accepted*. On 2026-10-01 the home server held forty-seven accepted own secrets and twelve accepted
 pair credentials, every one rotatable only by a person changing the software by hand and accepting
 the new value, and one pair credential sat *made* and wrong because nobody could accept the real one.
 The operator asked for every password in the vault and rotatable, and for a library manager's
 definition to receive the download client's credential and address through provisioning like
 anything else (filed as the forge's issue 243 on this repository).
 The address half already works: the library manager requires the download client's API provision,
 the provider serves scheme, port and user name, and the binding carries them. Only the credential
 half had no form.
 ## Considered Options
 1. **Keep accepting.** Honest about what the software can do and what the mesh cannot, and it is
   the state the home server was in: nothing rotates, a consumer added later needs a person, and an
   unknown predecessor password stays unknown for ever.
 2. **Put a login per consumer in front of the software.** A proxy that holds the one credential and
   issues many. A second service per provider, with its own credential to keep, to make the mesh's
   model fit software that does not share it.
 3. **Let the provider say its one credential is the credential.** An offer names which of the
   provider's own secrets *is* what every consumer receives. The vault keeps one record, sealed to
   the provider's machine, every current consumer's machine and the operator, and because it stores
   no plaintext it cannot seal an existing value to a later consumer — so it **remakes the value
   for all of them at once** whenever the set of consumers changes or a rotation is asked. The
   provider takes it the way an own secret is taken ([ADR 0114](0114-a-shared-credential-rotates-over-two-credentials.md),
   issue 180); consumers read it at start.
 ## Decision
 **Option 3.** A provider whose software holds one credential shares that credential, and the mesh
 owns its whole lifecycle.
 - **The offer says so.** `{"name": "download-client-api", "credential": {"own": "password"}}` on a
  provider's `provides` entry names one of its own secrets as the credential of that provision. The
  named own secret must say how it is taken (`taken: at-start` or `taken: applied`); an offer
  naming an undeclared or untaken secret is refused at parse.
 - **One record, many seals.** The vault keeps one value per (provider assignment, provision). It is
  sealed to the provider's machine, to each consumer's machine that currently binds the provision,
  and to the operator. Every consumer's binding file carries the provider's one user name and the
  secret file carries the shared value; the shape a consumer reads is the pair credential's, so a
  consumer's definition does not know whether its credential is shared.
 - **Remade for all, together.** When a consumer binds or unbinds, or `secret rotate` is asked on the
  provider's own secret, the vault makes a new value and seals it to every current holder in one
  act, and the mesh sends every holding machine. The provider restarts on the new value or applies
  it at start; each consumer restarts on it. There is no window between two credentials, because
  there is one credential; there is the restart, stated as the cost below.
 - **An accepted shared value is sealed to everyone the moment it is accepted.** `secret accept` on
  the provider's own secret is the one moment the mesh holds the plaintext, and it seals copies for
  every current consumer then. It is not remade afterwards ([ADR 0113](0113-the-vault-makes-every-secret.md)):
  a consumer that binds later is refused until the value is accepted again, in words that say so.
 - **A value the software issues itself stays accepted.** A token the media server obtains from its
  vendor cannot be set by the mesh; its provision keeps the accepted form until a module can deliver a
  value it did not mint to the vault, which this record does not build.
 - **Nothing changes for software that holds many logins.** ADR 0048's form stays the default; this
  is the form for an offer that says it has one credential.
 ## Consequences
 - The media stack's six providers stop needing a person per consumer. A library manager binding
  the download client gets a working credential the mesh made, and an unknown predecessor password
  is replaced by one the mesh knows, recoverable with the operator's key.
 - **Adding or removing a consumer restarts every consumer of that provision and the provider.**
  That is the price of one credential, and it is paid when a definition binds, not at an hour of
  nobody's choosing. It is stated in the plan's words when it happens.
 - Rotation of a shared credential is [ADR 0114](0114-a-shared-credential-rotates-over-two-credentials.md)'s
  single-party form across several machines: in place, all holders sent together. The staged form
  for a backend that takes its credential once is still not built, and a provider whose own secret
  says `applied` refuses rotation by name until it is.
 - The vault can name who holds a shared value — the copies are the record — so *who has this* stays
  a query, as design 13 requires.
 - The accepted count on the home server becomes a list that shrinks, provider by provider, as each
  one's start applies the file.
 ## How this is checked
 | Rule | Checked by |
 |---|---|
 | An offer may name one of its own secrets as its credential; an undeclared or untaken secret is refused at parse | manifest tests |
 | A consumer of a shared provision receives the provider's value as its pair credential, under the provider's one user name | resolver and declaration tests |
 | The record is sealed to the provider, every current consumer and the operator; a consumer binding or unbinding remakes it for all | inventory tests against a raised store |
 | Rotating the provider's own secret remakes every holder's copy, and an accepted value is sealed to current consumers once and not remade | inventory tests |
 | Live: a library manager on the home server binds the download client with a value the mesh made, the client takes it at start, and a rotation through the console reaches both | done by hand after the media catalogue's providers apply the file at start |
 *2026-10-01:* the first four rows pass in mesh-controller PR 184 (`make check` green); the live row waits for the first provider definition to say `credential` and `taken`.

 # 159. A tool call names the machine it is for, every answer says which machine answered, and a holder's runtime serves its seat's verbs
 ## Context
 [ADR 0152](0152-the-operators-surface-is-a-module-the-console.md) made a module's tools subjects on
 the bus and the console the place a person reaches them. [ADR 0154](0154-the-meshs-own-verbs-are-the-controller-seats-tools.md)
 made the mesh's own verbs the controller seat's tools, served by the controller. Design 33 said what
 a seat's tools are, that holding a seat means serving them, and that a node-scoped seat's verb
 carries the machine.
 What was built stopped short in two places ([issue 182](../04-ISSUES/182-a-tool-call-reaches-whichever-instance-answers-first/00-report.md)).
 A module's tools were one subject per module in one queue group, so with the database engine on two
 machines a call reached whichever instance answered first, unnamed, and nobody could ask one machine's.
 And no module served the verbs of a seat it held: the runtime did not know which seats its module
 claimed, and no seat but the controller's declared verbs. The operator named it: a tool call must be
 able to say *the store on the control node*, and the engine holding the store seat must serve the
 store's tools as well as its own.
 ## Considered Options
 1. **Leave the queue group and ask the controller which machine answered.** Nothing changes on the
   bus; a caller cannot choose, only learn afterwards. Useless for the question that was asked.
 2. **A subject per machine instead of one per module.** Every call names a machine; a stateless
   module on three machines loses the one-of-them answer a queue group gives for free, and every
   caller has to know where things run.
 3. **Both subjects, and the machine in every answer.** An instance serves its module's subject in the
   queue group as before, and the same subject with its machine as the last token. A caller that
   names no machine gets one instance and is told which; a caller that names one gets that one. The
   grant for a tool covers both. And a holder's runtime serves its seat's verbs by the same means,
   from what the credential tells it.
 ## Decision
 **Option 3.**
 - **Two subjects per tool, one default.** `mesh.mod.<module>.tool.<tool>` in the queue group, and
  `mesh.mod.<module>.tool.<tool>.<node>` served by the instance on that machine alone. In the
  caller's words, `<module>.<tool>@<node>`. A runtime that does not know its machine serves only the
  first, which is what it always did.
 - **Every answer says which machine answered.** The reply carries the node; the console appends
  *answered by <node>* as its own line after the module's unshaped answer, and `mesh call` prints it.
  An answer from a module on several machines is never an answer from nowhere.
 - **The console offers the machine on every module tool** as an optional `node` argument, lists it,
  strips it into the subject and never passes it to the module. A seat's verb takes none: the seat's
  scope decides where it is served.
 - **The grant covers both subjects.** `invokes: [<module>.<tool>]` permits the plain subject and the
  machine-addressed one; `*` already permitted everything beneath `tool`.
 - **A holder's runtime serves its seat's verbs.** The broker credential the mesh writes names the
  seats the module claims and, for each, its scope and the verbs the seat promises. The runtime
  serves each verb with the module's tool of the same name on the seat's own subject — flat for a
  mesh seat, with the machine for a node-scoped one — and the bus admits that subscription only
  where the module holds the seat, because the holder's grant is composed from the holding. A
  claimant that does not hold the seat here is refused the subscription and serves nothing. A
  claimant missing a tool a seat promises is already refused at registration (design 33 §3).
 - **The store seat's first verbs**, so the operator's question has an answer: `databases`, every
  database the store holds with its owner and size, and `query`, one read-only statement against one
  database. The database engine serves both as tools of those names and lists them in its definition.
  Which verbs a seat serves is a decision per seat and binds every holder; these two are the smallest
  set that makes the store askable.
 ## Consequences
 - *List the databases of the store on the control node* is `mesh-store.databases` through the seat,
  answered by its holder wherever it sits, or `postgres.databases@novox` through the module on one
  named machine. Both say who answered.
 - Every module's runtime serves one more subscription per tool and, for a claimant, one per promised
  verb. No manifest changes for the per-machine half; the seat half needs each holder's definition to
  list the seat's verbs among its tools, which registration already demands.
 - The runtime change reaches a module when the module is rebuilt on the new runtime image; until
  then that module answers only on its plain subject, and a call naming its machine is refused as
  unserved, in words that say so.
 - The credential gains `claims`; a module issued before this carries none and serves no seat verb
  until it is issued again. `rollout mint` for the holders is the one-time cost.
 ## How this is checked
 | Rule | Checked by |
 |---|---|
 | A call naming a machine reaches that machine's instance; an unnamed call reaches one and says which | mesh-tools, against a real bus: a module on two machines |
 | A claimant serves a seat's verb on the seat's subject, and the answer names the machine | the same test |
 | The console lists `node` on a module's tool and not on a seat's verb, and the answer carries *answered by* | mesh-tools, the MCP conformance test |
 | The grant for a tool covers the plain and the machine-addressed subject | `TestInvokingAToolMayAddressTheMachineToo` (controller) |
 | Live: the store's databases listed from the control node by name through the console, and through the store seat | done by hand after the roll-out and the catalogue's step |

 # 160. The mesh issues an assignment's subjects, and a runtime serves what it is issued
 ## Context
 A module's code names no subject. It registers tools by name and emits events by name, and design 29
 §1 says the rest: *the module names its event and the mesh decides where it lands*. What was built
 decided it twice. The runtime derives `mesh.mod.<module>.tool.<name>` from the module's name by a rule
 compiled into it; the controller derives the same subject by the same rule compiled into it, and grants
 it. They agree because two binaries carry one convention, which is the failure design 33 §2 names for
 seat protocols: *discovery that reads a binary disagrees with the mesh the moment the two are on
 different versions*. [ADR 0159](0159-a-tool-call-names-the-machine-and-a-holder-serves-its-seats-verbs.md)
 extended the convention this morning — a second subject per tool with the machine as its last token, a
 seat's verbs served from the credential's claims — and extending it made the shape plain: every such
 change is written in the runtime and in the controller, and a module whose instances must not be
 confused is told apart by a rule in a binary rather than by the mesh that assigned it.
 The operator put it in one sentence: the mesh knows the subjects, the modules do not; a module should
 ask what to listen on. This record decides exactly that.
 ## Considered Options
 1. **Keep the convention, keep it in two places.** Cheap until the next change; every change is two
   changes, and the mesh cannot vary a subject for one assignment without a rule for all.
 2. **Keep the convention in one place by putting it in the SDK alone**, and have the controller call
   the SDK's rule. The controller is Go and the SDK is TypeScript; one of them would still carry a copy.
 3. **The mesh issues the subjects.** For every assignment the controller composes a membership: what
   this instance serves, where, in which queue if any; the seat verbs it holds; where its events land;
   what it may reach and at which subjects. It publishes it to a subject only that assignment may read,
   kept last-per-subject so a runtime that connects late reads the current one. The runtime serves
   exactly the list and nothing it did not receive. The grant is composed from the same membership, in
   the same act, so the two cannot drift.
 ## Decision
 **Option 3.**
 - **A membership per assignment.** The controller composes, for a module on a machine, one document:
  the tools the module serves with the subject each is served on and the queue group if any; the seat
  verbs this instance serves and their subjects; the subject each of its events lands on; what it may
  reach — the tools it invokes, resolved to the subjects the mesh issued to those modules' instances —
  and what it consumes. The runtime registers tools and events by name; the membership says where.
 - **Published, not written into the definition.** The membership is a message on
  `mesh.assignment.<node>.<module>` in a stream that keeps the last per subject, like a node's
  declaration. The controller publishes it whenever the assignment's facts change: a push, a seat
  handover, an instance added elsewhere, an upgrade. A runtime reads the current one when it connects,
  serves it, and keeps reading, so a change reaches a running instance as a re-subscription rather
  than a restart.
 - **One bootstrap rule, and only one.** The credential names the node and the module; the membership's
  subject follows from those two names and nothing else, and the account may subscribe it. Every
  other subject is data in the membership. This is the one convention the runtime keeps, the way a
  resolver keeps the address of a root.
 - **The grant is the membership, read the other way.** What an account may subscribe is what its
  membership says it serves plus its own membership's subject; what it may publish is what its
  membership says it emits and reaches. One composition yields both, so a subject the runtime serves
  without a grant, or a grant for a subject nothing serves, cannot be written.
 - **Whether an instance answers for the module, or only for its machine, is the mesh's to decide.**
  A module on one machine is issued the module's plain subject and its machine's. A module on several
  is issued only its machine's unless its definition says its instances are interchangeable, a fact
  about the software and not about the bus; then every instance is issued the plain subject in one
  queue group as well. The console lists what the memberships say: a stateful module on two machines
  appears once per machine; a stateless one appears once.
 - **A caller composes nothing.** The console's listing carries each tool's subject; the SDK's call by
  name reads the subject from the caller's own membership, where the mesh wrote what it may reach. The
  shape of a subject is the controller's business and may change without any module or runtime
  changing.
 - **Today's shape is the shape issued first.** `mesh.mod.<module>.tool.<name>`, with the machine as the
  last token for an instance, and `mesh.seat.<seat>.tool.<verb>` with the machine for a node-scoped
  seat, are what the controller composes on day one, so nothing on the mesh moves when the
  membership arrives; only who decides it moves. [ADR 0159](0159-a-tool-call-names-the-machine-and-a-holder-serves-its-seats-verbs.md)
  stands for what it decided — a call names the machine, every answer names it, a holder serves its
  seat — and is extended in how: those facts are now issued, not derived.
 ## Consequences
 - The runtime loses its subject rule and its claims rule; it serves a list. The controller gains one
  composition and one stream; design 25 §2 and §3 gain a line each. The console loses `toolSubject`
  and reads subjects from the listing. The SDK's `invokeTool` reads the caller's membership.
 - A subject scheme change is a controller release and a republish of every membership, with no module
  rebuilt — the opposite of this morning's forty-three builds.
 - A membership can differ per assignment on purpose: an instance that holds a seat serves more; an
  instance the mesh wants quiet serves less; a module the mesh is retiring can be issued nothing and
  told so.
 - During the move, a runtime that finds no membership for its assignment falls back to the derived
  shape and says so in its log, so the wave of this change is a controller release followed by one
  push, and a runtime older than the change keeps working on the convention it carries.
 ## How this is checked
 | Rule | Checked by |
 |---|---|
 | A membership composed for an assignment and the grant composed for its account name the same subjects, both ways | a controller test over a module on one machine, on two, holding a seat, and declared interchangeable |
 | A runtime serves exactly the subjects its membership lists, and re-subscribes when the membership changes | a runtime test against a real bus: a membership published, served; republished with a subject removed and one added, followed |
 | A runtime with no membership says so and serves the derived shape | the same test, before any membership is published |
 | The console lists a stateful module on two machines once per machine, and composes no subject | the MCP conformance test |
 | Live: the store's databases asked of one named machine and through the seat, after a controller release and one push, with no module rebuilt | by hand |
 ## Built, 2026-10-01
 > **Progressive insight — 2026-10-01.** The decision stands; these are the facts of its building.
 - The controller's half: mesh-controller 188 — the membership, its subject, the assignments stream
  read directly, a module's account granted its own membership and nothing else of the stream, a
  membership published after each push.
 - The runtime's half: mesh-tools 23 — the one address derived, the membership read and followed,
  exactly the issued subjects served and re-served, the derived shape with a log line until one is
  issued, a seat's verbs implemented under the seat's name and never listed as the module's, the
  listing carrying subjects and the console composing none. A claim may now name the verbs it
  serves for its seat (mesh-controller 186), so a holder's own tools need not be the seat's.
 - What the first roll-out taught: the controller's own grant did not name the assignments it issues,
  so the first memberships were refused by the server and every runtime kept the derived shape —
  which is exactly the fallback this record asked for, and exactly why nobody noticed
  ([issue 183](../04-ISSUES/183-the-controller-could-not-publish-the-memberships-it-issued/00-report.md)).
  The SDK's `invokeTool` still composes a subject; it reaches a membership through the runtime's
  broker, which does, so the caller-side rule is met there and not yet in the SDK's own words.
 - Live, 14:55Z the same day, through the console: the console's runtime logged *was issued a new
  membership; re-serving on it*; `mesh-store.databases` answered by the control node, the seat's
  holder; `postgres.postgres_list_databases` with the machine named answered by that machine, on
  both machines that run it; `mesh-controller.push {node}` reached the seat's verb with its own
  argument intact. Three facts the proof taught: a runtime's first read of the stream must use the
  subject-addressed direct get, the only form its account is granted (mesh-tools 25); a module's
  bus credential is a minted secret written once, so a claim added to a definition reaches a running
  module only after `module issue <module> --node <machine>` and a push (postgres, both machines);
  and a registration under a seat the credential does not yet claim must be said and skipped, not
  fatal (mesh-tools 26).

 # 161. What deserves a seat: a role of a module is a seat, a singular fact about machines is a placement with a capacity of one, and a holder's software is the machine's
 ## Context
 Three issues asked the same question from three sides. The vault provides `secret` to the whole
 mesh and claims no seat, so nothing refuses a second vault by name
 ([issue 106](../04-ISSUES/106-the-vault-claims-no-seat/00-report.md)). The hub of the private
 network is a placement, `overlay place <node> --hub`, and the issue asked whether "there is exactly
 one hub" is a seat's shape ([issue 105](../04-ISSUES/105-the-hub-of-the-private-network-is-not-a-seat/00-report.md)).
 Three modules claim the one uplink seat, one per network manager a machine might run, and nothing
 checks that the holder names the manager the machine actually runs
 ([issue 138](../04-ISSUES/138-two-modules-claim-one-seat-and-are-not-interchangeable/00-report.md)).
 Read against the code on the day of deciding:
 - The mesh's own seats are five by [design 26](../03-DESIGN/01-to-be/26-the-seats.md)'s table and
  four in the controller's seed: `mesh-vault` is in the table and not in the seed, and the vault's
  definition claims nothing. The design also says `secret` is reserved; no parser or resolution rule
  reserves it. A second provider of `secret` would be a second candidate, settled by a pin.
 - The store already keeps one hub: a unique index since the overlay's first migration, and the
  placing command refuses a second hub naming the first. What 105 observed as silent is not.
  [ADR 0121](0121-a-system-seat-is-named-for-its-scope-and-modules-define-their-own.md) decided that
  the private network becomes a mesh-scoped seat held by a server module, with client modules —
  the overlay is the host's own today, so that seat has nothing to be held by yet.
 - A machine's capabilities are its profile, detected by the host at enrolment and never since, and
  resolution refuses a module on a machine lacking one it declares, naming the capability. The uplink
  holders declare `package-manager` and `service-manager`, which every machine has.
 [ADR 0126](0126-a-module-declares-its-own-seats.md) gave the reason the mesh's own seats exist:
 **the mesh's own code looks them up by name.** `mesh-store` is an identifier the controller
 dereferences, not a convention. That reason decides the first question; the other two are decided
 by what a seat is — a role held by a module assignment — and by what the mesh can check.
 ## Decision
 **1. A provision the mesh itself dereferences is delivered by a mesh seat its provider claims.**
 The vault's `secret` is one: the controller seals every minted credential with it. `mesh-vault` is
 the fifth seat of the mesh's own, mesh-scoped, delivering `secret`, under
 [ADR 0079](0079-the-foundation-seats-are-named-after-their-servers.md)'s convention; the vault's
 definition claims it; a second provider of `secret` is a second claimant and refused by name. The
 word *reserved* leaves design 26: the effect it described is the seat's. Every other mesh-scoped
 provision — `smtp`, `oidc-client`, `s3-bucket`, `route`, `acme-ca` and the rest — may have several
 providers, and a consumer with several and none local is a person's choice, as the glossary says.
 The test for "deserves a seat" is the question 0126 asked: does the mesh's own code find it by name?
 **2. A singular fact about machines is a placement with a capacity of one; a singular role of a
 module is a seat.** A seat is held by a module assignment and points at it; the hub is a machine,
 and the private network is the host's own until 0121's server and client modules exist. So the hub
 stays a placement, and what a seat would have given — refusal of a second by name, and the one
 named when asked — a placement of capacity one gives: the store keeps one (the unique index), the
 placing command refuses a second naming the one that stands, and the overlay listing names it.
 0121's seat for the private network stands, deferred with the split it needs. The rule generalises:
 a fact of the shape *exactly one machine is X* is a placement checked by the store and said by name,
 never a seat with no module to hold it.
 **3. A holder of a seat whose role is "speak to what this machine runs" must be the dialect the
 machine runs, and the machine says which.** The host's profile gains one capability per network
 manager found active — `uplink-networkmanager`, `uplink-systemd-networkd`, `uplink-dhcpcd`, each
 `systemctl is-active` of the manager's unit — and each uplink holder declares its own. Assignment
 then refuses the wrong holder with the refusal that already exists, naming the capability; nothing
 new is judged. The profile is detected again by every apply and travels in the report, and the
 controller keeps the latest, so a machine that switches managers is, at its next push, a machine
 whose holder lacks a capability: the plan refuses and names it, which is the one thing the machine
 is the only one to know. `node-uplink` stays one seat: its three holders are three dialects of one
 role, and the capability picks the dialect. One module speaking all three is allowed by this and
 built by nobody.
 ## Consequences
 - The controller's seed gains `mesh-vault`; the seat table takes it additively at the next start,
  as every seed row does. The vault's definition claims it, one release after the controller.
 - The uplink definitions declare their capability one release after the host reports it, or they
  are refused on every machine in between; the order is controller (the report carries a profile),
  host, then catalogue.
 - Design 26 loses the word *reserved* for `secret` and states rules 2 and 3; the uplink row of the
  seat table names the capability its holders declare.
 - Issue 106 is resolved by rule 1, 105 by rule 2 with nothing to build, 138 by rule 3.
 ## How this is checked
 | Rule | Checked by |
 |---|---|
 | `mesh-vault` is in the mesh's own set, mesh-scoped, delivering `secret`, and the vault claims it | a catalogue test on the default seats; registration refuses a second claimant by name (`CanHold`'s existing test, with the vault's seat) |
 | A second hub is refused naming the first, and the listing names the hub | the overlay command's test; the store's unique index |
 | A machine's profile names the network manager it runs, and is renewed by every report | a host detector test per manager; a controller test that a report carrying a profile replaces the stored one |
 | An uplink holder on a machine running another manager is refused, naming the capability | the existing capability refusal, exercised by a resolution test with a networkmanager machine and the systemd-networkd holder |
 | Live | `mesh-controller.seats` lists `mesh-vault` held by the vault on the control node; `plan` of a machine refuses the wrong uplink holder naming `uplink-<manager>` |

 # 162. A merge produces a tiered plan the mesh keeps, and a module's dependencies are one relation in the catalogue
 ## Context
 A merge on the forge reaches the controller as an event, and the controller asks the build
 machine for what that merge changed. Until today that meant the modules whose recorded source is
 that repository; since this afternoon it also means everything standing on what moved
 ([issue 186](../04-ISSUES/186-a-release-across-repositories-is-an-order-in-a-persons-head/00-report.md)).
 Both are done inside the handler that received the event: it asks one build, waits for it, asks the
 next, and returns when the last is done. Three things followed from that shape on 2026-10-01:
 - The controller hears nothing else for the length of the work — twenty-five minutes for the runtime
  image and its forty-three dependents ([issue 184](../04-ISSUES/184-a-merge-announcement-blocks-the-controllers-receive-loop/00-report.md)).
 - A controller replaced mid-merge loses the rest of the merge: the redelivered announcement reads as
  history, and the dependents are asked by hand.
 - Nothing is deployed between builds. A merge that changes the build machine and something the build
  machine builds asks for both in order, but the second is built by whichever build machine is running
  — the old one, unless somebody pushed in between. The order the dependents are sorted in exists for
  the artifacts; it says nothing about what must be *running*.
 And the knowledge the order is computed from is scattered: a manifest's `build.on`, the artifacts a
 build was made against, the repositories a build read, and the fact that every source-built module is
 built by the build machine, each read by a different function in the merge handler.
 ## Decision
 **1. A module's dependencies are one relation in the catalogue.** `depends-on` edges, each with the
 kind of dependency on it: `stands-on` (the module's artifact is built on the other's), `packages` (the
 module's build reads the other's repository), `built-by` (the module is built by the holder of the
 build-machine seat), and `declared` (a manifest's `build.on`). The relation is answered by one query
 of the catalogue — the controller's inventory today, the catalogue seat's tool when something outside
 the controller needs it — and nothing else computes an edge. The edges are derived from facts
 recorded at two moments and written by nobody: registration records the manifest (`declared`, and
 `built-by` for anything with a source), a build's take-in records what the image was built on and
 which repositories it read (`stands-on`, `packages`). A module's first build places it by its
 declared edges alone; from its second it is placed by what was true.
 **The kinds are three dependencies, not one.** A *code* dependency — B packages A's source — means
 B is rebuilt whenever A changes, in the same tier: B's build needs nothing of A's first. A *build*
 dependency — B stands on A's artifact, or declares it — means B is rebuilt after A is *built*, the
 next tier, and nothing need be deployed in between. A *runtime* dependency — B is built by A — means
 B is rebuilt only after A is built *and running*, the next tier with a gate on the machines' reports.
 One cycle is real and resolved by the kinds themselves: the runtime image is built by the build
 machine, and the build machine stands on the runtime image; the image comes first, built by the
 build machine that is running, which is the only one there could be — a `built-by` edge never orders
 a module after a build machine that stands on it. A provision is not a dependency of this relation:
 a consumer binds to its provider through what the push renders, and a change to the provider's image
 changes nothing in the consumer's; a consumer whose build does read a provider's source declares it.
 "A was deployed, so restart B" is the push's domain — B is replaced when what it reads changed — and
 not the plan's.
 **2. A merge produces a plan, and the plan is a record.** The controller takes the modules the merge
 changed and everything reachable from them along `depends-on` edges, and sorts that set into tiers:
 tier 0 depends on nothing else in the set, tier 1 only on tier 0, and so on. The plan — the merge it
 answers, the tiers, and each module's state — is written to the store before any build is asked. The
 handler asks tier 0 and returns. Every build's outcome, taken in by the same handler that takes every
 outcome in, advances the plan it belongs to; a controller replaced mid-plan resumes it from the store.
 **3. A tier is done when it is built, and when what the next tier needs from it is running.** A
 module whose roll-out policy says *roll out* is sent to its machines when it moves, as today. The next
 tier is asked only once every module in this tier is built and every rolled-out module of this tier
 that a later tier is `built-by` has been applied by the machines running it — the machines' reports
 say so. A module whose policy says *record* is built and not waited for. So a merge
 touching the build machine and the controller builds the build machine, waits until it is the build
 machine that is running, and only then asks for the controller's build.
 **4. A plan is read where the mesh is read.** `status` lists every open plan: the merge, the tier it
 is at of how many, what it is waiting for and since when; `builds` lists the asked beside the built.
 A plan that has waited past a bound is named red there, which is the first fact of
 [issue 187](../04-ISSUES/187-the-mesh-tells-nobody-when-it-stops-working/00-report.md)'s list.
 ## Consequences
 - The merge handler returns in milliseconds; the receive loop is never held by a build again. Issue
  184's remaining cause — a handler that waits for its own work — is removed rather than worked
  around; the bus's heartbeats stop being dropped under a merge.
 - A controller roll in the middle of a plan costs nothing: the plan is in the store and the asks are
  in the queue (mesh-controller 194).
 - A release across repositories is a plan whose edges cross repositories; the order a person kept in
  a work-order file is the order the tiers give. Issue 186's third fault is answered by the plan,
  not by a separate release record.
 - The explicit `build --on <base>` stays as the way to ask for the same plan by hand.
 - A module's `build.on` remains the one place a manifest states a dependency the store cannot see.
 ## How this is checked
 | Rule | Checked by |
 |---|---|
 | Dependencies are one relation, each edge with its kind | an inventory test over a fixture catalogue: a runtime image, a module on it, a module packaging the controller's source, and the build machine; the four kinds come back from one call |
 | A merge's set is sorted into tiers along the three kinds: a code dependency in the same tier, a build dependency after its base is built, a runtime dependency after the build machine; the build machine's own base first | a unit test on the tiering over the mesh's real shape: the runtime image, the build machine on it, modules built by it, a plugin declared on one, the proxy packaging the controller, an unrelated module left out; a cycle is one last tier and said |
 | Only a runtime dependency gates on deployment, and only for a module that rolls out | the same test's gate cases |
 | The plan is written before any build is asked, and the handler returns | a controller test: a merge announcement produces a plan row with its tiers and one asked build per tier-0 module, and the handler is back before any outcome |
 | An outcome advances its plan; a complete tier asks the next; a tier with a rolled-out base waits for the machines' reports | store-backed tests over a two-tier plan: the first outcome marks built; the tier's roll-out gate holds until the report; the next tier is asked after |
 | A controller restarted mid-plan resumes it | a test that opens a plan, drops the handler, and advances from the store alone |
 | `status` lists open plans and names one that waits past the bound | the status JSON test with a fixture plan |
 | Live | a catalogue merge touching a base and a dependent: the plan's tiers in `status`, the base rolled before the dependent is asked |
 ## Built and proven live, 2026-10-01
 > **Progressive insight — 2026-10-01.** The decision stands; these are the facts of its building.
 Built in mesh-controller 197 (the relation, the plan record, the driver, `status`), 198 (`plans`),
 199 (a `built-by` edge orders and gates but never widens — the first live plan had taken the whole
 catalogue along for a controller change; `plans stop`), 200. The first merge handled by the finished
 machinery, at 18:56Z, was a controller change and produced the plan this record describes: tier 0
 the build machine; tier 1 the controller and the proxy that packages its source. The handler
 returned at once; the build machine was built, rolled, and the plan read *tier 0 built; waiting for
 builder on novox to be applied* until the machine reported; then tier 1 was asked, both built, and
 the plan read done — three minutes, read through the console with `plans`, the receive loop taking
 reports throughout. What the day between decision and proof taught is in issues

 # 163. Taking a module over is a comparison: what it compares, what it refuses, and what it carries
 ## Context
 On an adopted machine the mesh holds what it finds until the module is taken, and taking is the
 cutover ([ADR 0100](0100-a-node-in-use-is-adopted-before-it-is-converged.md)). The whole-node flip
 is previewed and confirmed by digest; the per-module cutover, the step that actually replaces a
 running service, previews nothing. `take` names the held things the next push will replace and
 where each original is kept. It does not say how the module's version of each differs from what
 runs. Ten issues from the first migrations are the same omission seen from ten sides:
 - a port narrowed from everywhere to the private network, unannounced ([086](../04-ISSUES/086-taking-a-module-narrows-a-port-without-saying-so/00-report.md));
 - a configuration file replaced whole, dropping the one line that was the installation's own ([098](../04-ISSUES/098-taking-a-module-replaces-a-configuration-nobody-compared/00-report.md));
 - an image pin that had aged into a downgrade, discovered by three minutes of outage ([099](../04-ISSUES/099-a-modules-image-pin-ages-into-a-downgrade/00-report.md));
 - a secret minted for a service that already had one, with no way to carry the existing value in because it was a required secret and not the module's own ([100](../04-ISSUES/100-a-minted-secret-cannot-be-the-one-the-service-already-uses/00-report.md));
 - a container moved onto the module's own network, out of reach of the neighbour that called it by name ([101](../04-ISSUES/101-taking-a-service-reached-by-container-name-cuts-its-neighbours-off/00-report.md));
 - a resource whose target changed, leaving the old container running with no record naming it ([097](../04-ISSUES/097-a-resource-that-changes-target-leaves-the-old-one-behind/00-report.md));
 - a volume path that changed without the running container noticing, because the host does not compare that field ([126](../04-ISSUES/126-a-volume-path-is-not-in-the-spec-comparison/00-report.md));
 - a build that deployed at once because the module's policy said so, racing a data move ([126](../04-ISSUES/126-a-volume-path-is-not-in-the-spec-comparison/00-report.md));
 - a setting accepted where it was set and refusing the whole machine where it was read ([096](../04-ISSUES/096-a-setting-that-cannot-work-is-stored-and-stops-the-node/00-report.md));
 - a module that could not take over what genesis raised, because the two differed in name, network, data and image ([090](../04-ISSUES/090-the-forge-module-does-not-take-over-the-forge-genesis-raised/00-report.md));
 - a successor that could not stand beside its predecessor at all, answered by [ADR 0104](0104-a-provision-may-be-answered-by-an-adapter-to-the-predecessor.md)'s adapter ([093](../04-ISSUES/093-the-successor-proxy-cannot-serve-what-the-predecessor-still-serves/00-report.md)).
 What the host records of a found thing is enough to compare from: a file's original, kept, with
 its digest, mode and owner; a container's id and whether it ran; whether anything changed it
 since. What it does not yet record is what a comparison needs most: the found container's image
 and when that image was made, the networks it is on and who else is on them, what it mounts, what
 it publishes. And the controller's rule that a machine is told everything or nothing turns one
 impossible statement into a machine nobody can talk to.
 ## Decision
 **1. A take is previewed, and the preview is a comparison.** For every held thing the module would
 replace, `take` puts what runs beside what the module declares and says the difference:
 - a **container**: its image against the module's, with each image's creation date so older and
  newer have a meaning; its name; its networks, and the other containers on each found network
  that is not the module's; its published ports and the reach of each, found firewall and guard
  included; its mounts against the module's volumes and paths;
 - a **file**: the kept original against the declared content, as a difference, not two digests;
 - a **secret** the module takes that the mesh minted and nobody accepted, when the service's data
  was found — a service that already runs already has a value;
 - the module's **settings** on that machine, composed against its definition.
 `take` without `--yes` prints the comparison and stops; `take --yes <digest>` cuts over exactly
 what was previewed, the way the flip is confirmed, and a preview whose account of the machine is
 older than the flip allows is refused the same way. The host supplies the facts in its report of
 what it holds: the found container's image and its creation date, its networks and their members,
 its mounts and published ports.
 **2. Three differences refuse by default, each overridden by naming it.** An image **older** than
 the one running, by creation date — `--downgrade`, said once and recorded. A declared file that
 **differs** from the kept original — `--replace <path>`, or the module declares the file partially
 and writes into it ([ADR 0102](0102-the-mesh-writes-into-a-shared-file-never-over-it.md)), which is
 the right answer wherever the file is the service's own and the format allows it. A **minted,
 unaccepted secret** for a service whose data was found — accept the value first, or `--mint
 <name>` to say the service shall take a new one. Two differences are said and not refused: a port
 whose reach **narrows**, and a found network whose other members may reach the container **by
 name**, each member named; both are the operator's to weigh, and the words are there to weigh them.
 **3. A secret the mesh would mint may be accepted instead, own or required.** `secret accept`
 reaches a module's required secrets, not only its own: the value is a fact about the machine, and
 the mesh's job at a take is to learn it. The accepted value is sealed to the module as a minted one
 would be, and the provider that would have minted it is told it has one. Whether one accepted
 value should reach every consumer of a provider at once is [issue 165](../04-ISSUES/165-one-accepted-value-must-be-accepted-once-per-consumer/00-report.md)'s
 question and the next group's.
 **4. A taken container may keep a found network, for a while, by a setting.** A per-machine
 setting names a found network the module's container also joins, so a neighbour that resolves it
 by name keeps resolving it. It is migration scaffolding in the sense of
 [ADR 0104](0104-a-provision-may-be-answered-by-an-adapter-to-the-predecessor.md): assigned only on an
 adopted machine, reported while it stands, removed when the neighbours are taken, and the preview
 names it. Taking a group of modules at once is not decided here; the setting makes the order free.
 **5. The host compares every field it writes, and removes what it can no longer name.** A
 container is current when every field the host would write agrees with the one running — volumes
 and paths included; a field the host cannot compare recreates rather than passes. The host's
 record keeps a resource's former targets: a container or file the host **wrote** under a name or
 path the declaration no longer names is removed on the next apply and said; what was **found** is
 never removed, as ADR 0100 says. And the host answers the question nothing answered on
 2026-09-23: its report lists what runs on the machine that the mesh neither wrote nor holds —
 containers and listeners — as *strays*, so a thing left behind is seen the day it is left.
 **6. A setting is judged where it is stored, and an impossible one costs a module, not a machine.**
 Storing a setting composes it against the module's current definition and refuses with the node,
 module, layer and key when it cannot work. A definition that later moves under a stored setting
 makes composition leave *that module* out of the machine's declaration — its held things kept, its
 containers untouched — and say the statement by name; the machine is still told everything else.
 A machine is told everything or nothing about what it *is* told; what it is not told is said.
 **7. What genesis raises, it raises as the module that succeeds it declares** — name, network,
 data directory and image — so the module adopts it by the found rule that already exists, and a
 module meant to succeed a bootstrap service that it cannot adopt is a fault of genesis, found by a
 test that raises and then assigns. **`build` says when a policy will act on its result**, so a
 person choreographing a data move knows which module will not wait; under
 [ADR 0162](0162-a-merge-produces-a-tiered-plan-the-mesh-keeps.md) the roll-out is the plan's, and
 the plan says it too.
 ## Consequences
 - `take` becomes the per-module twin of the flip: preview, digest, confirm. The flip's own preview
  gains the same comparisons for every module it takes.
 - The host's report of what it holds grows by the found container's image and creation date,
  networks and members, mounts and published ports; its store keeps former targets and strays.
 - Issues 086, 098, 099, 100, 101 close on rule 1 and 2; 097 and 126 on rule 5; 096 on rule 6;
  090 on rule 7; 093 is closed by ADR 0104's adapter, which runs.
 - Nothing here changes what an adopted machine keeps or when: found stays held, held is never
  removed, the original is kept before anything is written.
 ## How this is checked
 | Rule | Checked by |
 |---|---|
 | The host reports a found container's image and creation date, networks and their members, mounts and published ports | host unit tests over a fake runtime; the adoption bed's report |
 | `take` without `--yes` previews every held thing's difference and changes nothing; `--yes` with the digest cuts over; a stale account is refused | controller tests over a fixture report: a differing file, an older image, a narrowed port, a shared network, a minted secret |
 | An older image, a differing file and a minted secret for found data refuse without their override | the same tests |
 | A found network kept by a setting is joined, reported and named in the preview | a host test and a controller resolution test |
 | `secret accept` takes a required secret | an inventory test; the provider is told |
 | Every container field is compared; a former target the host wrote is removed and said; what was found is not | host tests: a volume path change recreates; a renamed container's predecessor is removed; a found one under the old name is kept |
 | Strays are reported | a host test over a fake runtime with a container nobody declared |
 | A setting that cannot compose is refused where stored, naming node, module, layer, key; a definition moving under one leaves that module out and says so | controller tests |
 | Genesis raises the forge as its module declares it | a genesis test that raises, assigns, and finds the module holding rather than raising a second |
 | Live | the next cutover on an adopted machine: `take` shows the comparison, refuses the downgrade if there is one, and the service keeps its configuration and its secret |

 ## 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.
 ## Where this repository sits

+has, public, read by a module the mesh assigns, and edited nowhere else.
 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.

 The schema column added for this defaults to empty rather than null, because "not on a seat" is a
 real answer, so every row recorded before the change keeps exactly the meaning it had.
 ## 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.

 # 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.

 *Added 2026-09-30, from [issue 148](../../04-ISSUES/148-a-manifest-outside-this-catalogue-has-no-check/00-report.md).*
 The check the mesh applies at registration — the manifest parses strictly, every name in it is a
 usable one, its routes and events and seats are well formed, and no two manifests given together
 declare one seat — is a verb on the controller's binary, `module check <manifest>…`, and it needs no
 mesh. It reads the files it is given, runs the same functions registration runs, prints every problem
 in the manifest's own words, and exits non-zero if there was one. Somebody describing their own
 application in their own repository — the case [ADR 0037](../../02-DECISIONS/0037-where-a-module-lives.md)
 calls the one that matters most — runs it before pushing, and finds out there rather than when a
 running mesh refuses the registration, or later, when a machine applies something that resolved and
 should not have.
 **What it cannot know, it says.** A seat another module declares elsewhere is unknown to a check that
 was not handed that module's manifest, and the output says so rather than refusing: pass the other
 manifest too. The mesh's own seats it knows from the binary, which is the one place that set may be
 read without a store ([ADR 0122](../../02-DECISIONS/0122-a-seat-is-data-a-rename-is-a-database-update.md)
 keeps the store authoritative, so a claim on a mesh seat is judged fully only at registration, and the
 check says that too).
 *How it is checked:* the controller's test runs the check over the catalogue checkout beside it and
 over a manifest with a known fault, and asserts the first passes and the second names the fault; the
 test that used to be the only check, `TestEveryCatalogueManifestParses`, now stands beside a command
 anybody can run.

 ## A build says what it does, as it happens
 *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. 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.
 *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.

 ### A provider with one credential
 *Decided 2026-10-01 ([ADR 0158](../../02-DECISIONS/0158-a-provider-with-one-credential-shares-it-with-every-consumer.md)); the controller's half built the same day (mesh-controller PR 184): the offer's word, the need carrying the shared secret's name, the vault's one value under one generation stamp, remade for every holder on a later binding or a rotation, the rotate command sending every holder. What remains is each provider's definition saying `credential` and `taken`, with a start that applies the file — the media catalogue's work.*
 Software that holds one credential — a download client's web password, an indexer's one API key —
 cannot give each consumer a login, so ADR 0048's form does not fit it and its values were accepted
 by hand. An offer may now say `"credential": {"own": "<secret>"}`: the provider's own secret *is* the
 credential every consumer of that provision receives, in the shape of an ordinary pair credential,
 under the provider's one user name. The vault keeps one value per provider assignment and provision,
 sealed to the provider's machine, each consumer's machine and the operator; because it holds no
 plaintext it remakes the value for every holder at once when a consumer binds or unbinds or a
 rotation is asked, and the mesh sends every holding machine together. The provider takes it as it
 says it takes its own secret (`taken`, issue 180); consumers read it at start. An accepted value is
 sealed to the consumers of the moment and not remade; a consumer that binds later waits for the next
 acceptance. *How it is checked:* the rows of ADR 0158's table; the controller's rows pass, the live row waits for the first provider.

 **What deserves one** ([ADR 0161](../../02-DECISIONS/0161-what-deserves-a-seat.md)). A provision the
 mesh's own code dereferences by name is delivered by a mesh seat its provider claims — the store, the
 bus, the vault, the artifact store, the catalogue. A provision a module merely offers may have several
 providers, and a consumer with several is a person's choice. A fact of the shape *exactly one machine
 is X* — the hub — is not a seat, because a seat is held by a module assignment and points at it; it is
 a placement with a capacity of one, kept by the store, refused by name when a second is placed, and
 named in the listing. And a seat whose role is to speak to what the machine runs — the uplink — is
 held only by the dialect the machine runs: the machine says which in its profile, renewed with every
 report, and the holder declares the capability, so the wrong one is refused the way any missing
 capability is.

 Revision, [ADR 0162](../../02-DECISIONS/0162-a-merge-produces-a-tiered-plan-the-mesh-keeps.md). The
 trigger exists: the forge announces a merge on the bus and the controller acts on it (ADR 0157 made
 the build narrate; this makes the merge a plan). A module's dependencies are one relation in the
 catalogue — `depends-on` edges of four kinds: stands-on, packages, built-by, declared. A merge takes
 what changed and everything reachable from it along those edges, sorts the set into tiers, writes the
 plan to the store, asks the first tier and returns. Each outcome advances the plan; a tier whose
 rolled-out modules a later tier is built by waits until the machines report them applied; a
 controller replaced mid-plan resumes from the store. `status` lists open plans and names one that
 has waited too long. The transition discipline for breaking changes in the list above is still
 unwritten, and still the next thing.

 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.

 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.

 # 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.
 **Every module tool takes the machine to ask** (*2026-10-01*, [ADR 0159](../../02-DECISIONS/0159-a-tool-call-names-the-machine-and-a-holder-serves-its-seats-verbs.md)):
 an optional `node` the console lists on each one, puts into the subject and never hands to the module,
 for a module that runs on several machines; without it whichever instance answers first does, and the
 console appends *answered by <machine>* to every answer. A seat's verb takes none; the seat's scope
 decides. *Later the same day ([ADR 0160](../../02-DECISIONS/0160-the-mesh-issues-an-assignments-subjects-and-a-runtime-serves-what-it-is-issued.md)):* the console composes no
 subject at all; each tool's subject comes with the listing, and a stateful module on two machines is
 listed once per machine because the mesh issued it no plain subject.
 **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.

 forge and answering `records_search`, `records_read`, `records_list`, `records_status` and

 "beside everything else" lives in a mesh with no store. Design
 [35 — Reading the record](../../03-DESIGN/01-to-be/35-reading-the-record.md). The module's test runs

 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
 days are in this repository by hand.

 ## Resolved, 2026-09-30 — the module's half; the mesh's half is issue 174
 **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.

 ## Resolved, 2026-09-30
 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).

 were rewritten anyway because this catalogue is public; **a service's public name is the name the mesh
 composes for its route**, read through the route's binding, and an operator's own value is a setting;
 **a build context names a repository on the git seat**, `seat: git` with the path, and a context in
 another mesh's forge stays a URL, which the check reports and `names-on-purpose` would declare. The
 seven values that remain are declared with their reason — four applications built outside the mesh —

 ## Answered, 2026-09-30
 The work order's question — does the mesh grow its own operator surface, or is the surface an
 ordinary module — is answered by [ADR 0152](../../02-DECISIONS/0152-the-operators-surface-is-a-module-the-console.md):
 **the console is a module.** `mesh-console` is assigned to the machine a person sits at, holds a
 credential the mesh minted, calls tools under a grant its manifest declares (`invokes`), and serves the
 mesh's tools on that machine's loopback to an agent over MCP and to a person through the same endpoint.
 Designed in [34 — The console](../../03-DESIGN/01-to-be/34-the-console.md).
 What that leaves, said plainly so nobody reads this record as closed on the whole of its first
 paragraph: the console reaches every tool a *module* serves. The mesh's own questions — what a node
 runs, what is assigned — are the `mesh-controller` seat's tools under ADR 0132 and are not on the bus
 yet; for those a shell is still the way, and design 33 is where that closes.
 The predecessor's program on the workstation is not replaced by the mesh; it is left where it is and
 the assistant is pointed at the console beside it. The `hal` entry in the assistant's configuration
 still names things that are not the mesh's.
 **Verified live, 2026-09-30 evening.** The four pull requests merged; the console was registered
 (checked first with `module check`), built, assigned to a workstation, issued a bus account, and pushed.
 On that machine `tools/list` answered on loopback with 62 tools and named 36 modules as not answering,
 and a call to the forge's `gitea_list_repos` returned repositories. The assistant on that machine now
 lists the console as a connected MCP server beside the predecessor's program, which was left where it
 is. As-is: [`13-the-console.md`](../../03-DESIGN/00-as-is/13-the-console.md).

 # 153 — An adopted machine's data cannot be placed where it is
@@ -55,3 +55,25 @@ The two assignment halves 0112 decided: a setting that places a declared directo
 path on this node, and a setting that says where an access's data is — both validated like
 `endpoints` (unknown ids refused), and an access placed by the assignment still never created,
 chowned or removed.
 ## Resolved, 2026-10-01
 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.

 # 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.

 On ace, jackett's API key is the pair credential for sonarr, radarr, lidarr and bookshelf; sonarr's is

 `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.

 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.

 Making every dependency on ace a provision turned soft dependencies into hard ones. grafana now

 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.

 The download-stack write-in step (register download clients and torznab indexers through the Servarr

 Settings merge key by key into **every** `"merge": "json"` file of a module **and** every contribution

  `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.

 # 169 — A machine shares its files, and the mesh does not know
 ## What was observed
 ace serves the operator's media library to the home network with two host services no module
 declares and HAL never managed either:
 ```
 /etc/exports:   /storage/media  192.168.1.0/24(rw,sync,root_squash,…)     nfs-server active, :2049
 /etc/samba/smb.conf: [media] path = /storage/media/  valid users = media   smb active, :139/:445
 ```
 Two LAN clients were connected at survey (2026-09-30). The library itself is operator data
 (ADR 0051: ~40 TB on ZFS, the mesh owns nothing about it — [issue 153](../153-an-adopted-machines-data-cannot-be-placed-where-it-is/00-report.md)
 is about modules reaching it in place).
 Under the mesh as it stands, this arrangement has no expression and one failure mode:
 - **Nothing declares the listens.** At `converge ace` the filter is the sum of what modules listen
  on (ADR 0045); 2049 and 445 are nobody's, so the shares close — silently, for the two clients
  that mount them.
 - **Nothing owns the configuration.** `/etc/exports` and `smb.conf` are hand-written files on one
  machine; a second machine sharing a directory would be written by hand again.
 - **Nothing can consume it.** A module on another node that wanted the library (a player, an
  indexer, a backup) has no `requires` to state and no binding to read; it would mount by a
  hand-typed host and path.
 - The clients are LAN devices, so this also meets [issue 154](../154-a-machines-own-network-is-not-a-reach/00-report.md)
  (no reach for the machine's own network).
 ## The proposal (the operator's, 2026-09-30, settled after two rounds)
 **Two module-defined seats, one per protocol, because NFS and SMB share an intent and not a
 contract.** A seat in the mesh's sense is a contract — what it accepts, emits and serves, and the
 tools its holder must answer (ADR 0126, 0132) — and lined up, the two share almost none of it:
 | | `nfs-share` | `smb-share` |
 |---|---|---|
 | serves | export path(s); the client ranges allowed (`sec=sys` authorises by address) | share name(s), path |
 | pair credential | none | a user and password per consumer |
 | consumer's mount | `at:/path` | `//at/share` with credentials |
 | holder's tools | export / unexport a path for a range | add / remove a share, create a user |
 One `file-share` seat would be the union with every field optional — a consumer could bind it and
 still not know how to mount what it got (the emptiness ADR 0129 warns against). "Export a path to
 the network" is a category, and the mesh needs no seat category: a consumer requires the one it
 can mount. If "give me the library, however" is ever needed, it is a provision an umbrella module
 serves, not a seat.
 Both are node-scoped, one holder per node (ADR 0110), so ace holds both. `nfs` and `samba` are the
 first implementations; a second (Ganesha for `nfs-share`, ksmbd for `smb-share`) is what proves
 0126's promise that "replacing the implementation changes nothing for any caller".
 The holder module:
 - declares the exported paths as `accesses` (ADR 0051: it owns nothing about them — never creates,
  chowns or removes), and *which* paths as the assignment's settings (ADR 0046/0112);
 - writes the share configuration (`/etc/exports`, `smb.conf`) as mesh-managed files and drives the
  units, like `dnsmasq`/`sshd` do for theirs;
 - declares its endpoints (`nfs` 2049/tcp; `smb` 445/tcp, …) so the reach — internal, or the LAN
  once 154 has an answer — is the assignment's, and converge keeps them open;
 - **provides** the seat's provision, so a consumer on another node `requires nfs-share` (or
  `smb-share`) and reads `${bound:nfs-share:at}` and the path from its binding instead of a
  hand-typed mount.
 ## The design gap this exposes
 **A seat definition has no home outside the module that first declared it.** Today a seat is
 declared inside a manifest (`showcase` declares `the-showcase`, `ca-trust` its own). If `nfs`
 declared `nfs-share`, Ganesha could hold it only by depending on nfs's manifest — the coupling
 0126 removed for callers, reintroduced for implementations. The protocol needs a neutral place in
 the catalogue beside the modules (a seat definition registered like a manifest), with a module
 saying which seats it implements. This is the first role with an obvious second implementation,
 which is what makes it the exemplar for that mechanism.
 ## The consumer's half: a module mounts it (2026-09-30, third and fourth round)
 A binding tells a consumer *where* the share is; it does not put the files on its machine. Mounting
 is something done on a machine, and something done on a machine is a module's work — not the host's
 (the vocabulary stays closed; no `mount` resource kind).
 **A consumer-side module, `network-share` — the module responsible for setting up the network
 shares a node uses** (the operator's framing). A node role, like `node-uplink` or
 `node-dns-resolver`: each machine has it at most once, which is a reason for it to hold a
 node-scoped seat, so two modules can never both be writing mount units on one machine. Assigned on
 the node that wants the files:
 - `requires nfs-share` (or `smb-share`); several shares on one node are several local names of
  the requirement (ADR 0094);
 - its manifest is a `package` (nfs-utils), a `file` writing a systemd `.mount` unit filled from
  the binding — `What=${bound:nfs-share:at}:${bound:nfs-share:path}` — and a `service` enabling it
  after the overlay is up: the same shape as `resolv-conf` or `sshd`, files and a unit;
 - *where* it mounts is the assignment's setting (`/srv/media` on one machine, elsewhere on
  another); which machine mounts what is an operator decision made at assignment, exactly as which
  paths a machine shares is.
 **The modules that use the files never learn about NFS.** A player, an indexer, a backup declares
 the mounted path as an `access` — an operator-chosen, pre-existing path the mesh never owns
 (ADR 0051), exactly as `/storage/media` is on ace. The same app manifest then runs on ace against
 the local library and on another node against the mounted one, with only its assignment differing.
 **The one check to add, because it is the data-loss case.** An `access` is confirmed today by the
 path being present. For a mountpoint that is not enough: a writer whose container starts before the
 mount is up writes into the empty directory underneath it, and the files vanish when the mount
 lands. The access check must confirm the path is *a mountpoint* when the module says so (or the
 module's unit is ordered before the consumer's container — which crosses modules and is exactly
 what the mesh does not order). Which of the two is the decision's.
 **Identity crosses the wire.** `sec=sys` NFS trusts the client's uid, so a consumer must run as the
 library's owner on the server (ace: `media`, 1001:2000) — hq 153's `${access:<id>:uid}`, read from
 the mounted tree, answers it on the consumer's side too.
 ## Open questions for the decision
 - Whether an NFS export over the overlay is an `internal` reach of the same endpoint or a second
  export line — NFS authorises by client address, so the mesh range and the LAN range are two
  entries in one file.
 - How a consumer's binding expresses a *path* to mount (today bindings carry `at`, `port`, `as` and
  whatever the provider `serves`), and whether one share can serve several paths.

 # 170 — Assigning a module claims every seat it could hold
 ## What was observed
 ace's migration needs a postgres of its own: the operator's decision is that a `postgres` module
 assigned on ace provides `postgres-database` to ace's modules and has **nothing to do with the
 `mesh-store` seat**, which novox's assignment holds by a deliberate act already taken ("make
 novox's postgres the mesh-store").
 `assign ace postgres` (2026-09-30):
 ```
 ace is assigned postgres
 AND 1 other machine(s) cannot be worked out as things stand, so nothing will be sent to them:
  novox
    - postgres on novox claims "mesh-store", which postgres on ace already holds — one per mesh
 mesh-controller: these assignments cannot be applied:
  - postgres on ace claims "mesh-store", which postgres on novox already holds — one per mesh
 ```
 The second assignment did not merely fail: it made **the control plane's own store's
 assignment unresolvable** until unassigned. Nothing was pushed; the state is restored.
 ## Why
 `resolve.go` derives what a node holds from the manifest's `claims` of every module resolved on
 it, so a claim in a definition is a claim by every assignment of that module. The deliberate
 act ADR 0110 describes exists beside it — `seat …` records "X on Y as its standing holder"
 (`HoldSeat`) — but resolution does not consult that record; it consults the manifests.
 ## What was decided
 [ADR 0110](../../02-DECISIONS/0110-a-seat-is-a-module-assignment-from-a-closed-set.md):
 > **A definition says which seats a module *can* hold. An assignment says which it *does*
 > hold.** The store module can hold `mesh-store`, and it may be assigned to every node. Exactly
 > one of those assignments holds the seat, because that assignment said so.
 The manifest's `claims` is being read as *does hold*.
 ## What would be right
 Resolution takes the holder of a seat from the recorded holding (the seat's standing holder),
 not from the manifests: a module whose definition can hold a seat is assignable anywhere, and only
 the assignment recorded as holder claims it — with the refusal reserved for a second *recorded*
 holder at the seat's scope. Assigning postgres to ace is then exactly what the operator said it
 is: a database provider on ace, and no more.
 ## Until then
 `postgres` cannot be assigned on any second node; ace's database windows (baserow, letta, n8n,
 car-hunter, txt-game) wait on this.

 # 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.

 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.

 # 178 — A routed name resolves to a provider that was merely told it, and flips between plans
 ## What was observed
 From the home server, the dashboard's public name resolved inside the mesh to the control node, where
 no proxy serves it, and TLS failed; from outside it resolved to the home server and worked. Filed
 first in the forge's tracker on the hq repository (its issue 227), on 2026-09-30. The same night,
 two plans of the same machine taken a minute apart differed in exactly one resource — the mesh's
 names region — with the dashboard's name on one node's address and then on the other's.
 A second thing hid behind it: no module that is routed under several names — the photo service's
 six, the invoicing service's two, the mail server's five — had any of them in the names region at
 all.
 ## Why this is here
 The names region is composed from every contribution the mesh gave a name to. A consumer that is
 routed contributes its label to its route, and the proxy serves the composed name. A consumer that
 also uses an identity provider contributes the same label there, because the provider must know the
 consumer's public name to compose a redirect — and by the rule that two readers must agree
 ([issue 122](../122-a-module-cannot-ask-for-its-own-public-name/00-report.md)) it is
 given the same composed name. So one name reaches two providers, and the code attributed it to the
 node of whichever contribution a map yielded last. Map order is not stable between runs; the region
 was not either.
 The second fault is older: the single-value reading of a module's contributions is deliberately
 empty when the module contributes several times to one requirement
 ([ADR 0094](../../02-DECISIONS/0094-a-module-may-hold-several-secrets-from-one-provider.md)'s
 sibling), and the names region used that reading, so a module with several routes named none.
 ## Resolved, 2026-10-01
 Every node's resolution is read first, and the names are attributed across them at once. **The
 terminus serves the name**: among the providers a name reaches, the one that is not itself published
 under a labelled name through another provider. An identity provider is routed through the proxy and
 so is a consumer of names, not their end; the proxy contributes no label to anyone and is. The rule
 knows nothing of what "route" means — it reads the graph the modules declared — and it walks nodes,
 requirements and contributions in order, so one mesh yields one region. Every shape of contribution
 is counted, so a module routed under several names has every one of them resolved.
 *How it is checked:* the two-node mesh of the report, resolved and attributed twenty-five times — the
 dashboard's name on the home server, the identity provider's own name on the control node, no name
 leaked to the identity provider; a module with two routes yields two names; and, live, two plans of
 the home server after the roll-out identical in the names region, with the dashboard's name at the
 home server's address and the several-routed modules' names present.
 ## Note on where this was filed
 The symptom was filed in the forge's issue tracker, which is not where hq's issues live: a tracker
 issue carries no status the mesh's records read, and its numbers collide with hq's pull request
 numbers in conversation. It is closed there pointing here.

 # 179 — An adopted identity provider's admin never took the secret the mesh minted
 ## What was observed
 Filed first in the forge's tracker on this repository (its issue 228, 2026-09-30). The identity
 provider's sidecar failed every call with *401 invalid_grant, Invalid user credentials*, and the
 server logged a login error for `admin-cli` every five seconds. The provisioner that creates a client
 for every consumer of `oidc-client` could never create one, so the dashboard's and the car service's
 single sign-on on the home server failed at the identity provider. Not new that day: present since
 the module moved to the mesh.
 ## Why this is here
 The manifest mints an `admin` own-secret and renders it into the server's environment and the
 sidecar's file. The server reads that variable only when it creates its master realm. This instance
 was adopted with its database, whose `admin` user dates from 2022; the real password predates the
 mesh, and the minted one was inert from the first start. An own-secret the mesh mints is a statement
 the module's software is expected to honour, and adopted software that already holds its own
 credential does not — the same shape as the download client's web password on the home server
 ([ADR 0092](../../02-DECISIONS/0092-an-operator-delivers-a-pair-credential.md)'s
 operator-delivered secret), met from the other side.
 ## Resolved, 2026-10-01
 Reality was made to match the mesh rather than the mesh told about reality: the server's own
 bootstrap command created a temporary admin, that admin set `admin`'s password to the value the
 mesh minted — read from the sidecar's mounted secret on the machine, never printed — and the
 temporary admin was removed. Within a minute the sidecar listed realms through the console, and the
 two consumers' clients, `mesh_ace_grafana` and `mesh_ace_carhunt`, existed in the realm.
 The alternative, `secret accept` with the real password, was not available: the predecessor's
 configuration directory is gone and the password with it. For the next adopted module that holds a
 credential the mesh mints, the choice is the same, and the mesh's word for the second path is still
 only the download client's: a credential the mesh cannot make is the operator's to deliver.
 *How it was checked:* `keycloak_list_realms` through the console answers; `keycloak_list_clients`
 on the realm lists both mesh-named clients; the server's log stops the five-second login error.
 ## Open
 The manifest still says the admin password is the mesh's to mint, which is true of a fresh install
 and false of an adopted one, and nothing in a definition can say which it will be. Whether an
 own-secret should be acceptable the way a pair secret is — `secret accept <node> <module> <name>`
 already exists and takes an own-secret — is a sentence for design 27's operator provider, not taken
 here.

 # 180 — A module's own secret cannot be rotated, and nothing rotates from the console
 ## What was observed
 Filed first in the forge's tracker on this repository (its issue 231, 2026-09-30), after a module's
 API token was printed by accident on the home server and the only way to change it was to generate
 a value by hand and `secret accept` it. The report said there was no rotation at all. That was half
 right: `rotate <provision>` has existed for a pair credential since design 13, pushing both ends
 together; what did not exist was any rotation of a **module's own secret** — a token, an application
 secret, an administrator — and any way to ask for either through the console
 ([ADR 0152](../../02-DECISIONS/0152-the-operators-surface-is-a-module-the-console.md)).
 ## Why this is here
 [ADR 0114](../../02-DECISIONS/0114-a-shared-credential-rotates-over-two-credentials.md) decided how a
 single party's credential rotates: in place, in one of two forms. **Read at start** — the vault
 delivers the new value as current and the party is started again. **Applied** — the party's own
 code applies the value to a backend that takes it once, so the new value must be staged beside the
 current one until the party confirms it. Neither form was built, and nothing said which form a given
 secret needed. That last gap is the dangerous one: [issue 179](../179-an-adopted-identity-providers-admin-never-took-the-minted-secret/00-report.md)
 is what a value looks like when the mesh believes it was taken and the software never read it. A
 rotation that made that happen on purpose would be worse than no rotation.
 ## Resolved, 2026-10-01 — the read-at-start form, and the verb
 **An own secret says how it is taken.** In a definition, `"own-secrets": {"api-token": {"path": …,
 "taken": "at-start"}}` says the module reads the file when it starts; `"taken": "applied"` says its
 own code applies the value to a backend; a path alone says neither. A definition that says neither
 is not rotated by the mesh, and the refusal names the word to write.
 **`secret rotate <node> <module> <name>`** makes the secret anew the way the first mint did, seals it
 to the machine and to the operator, and sends the machine, so the module starts again on the new
 value, under the same `restart-on` that any changed file triggers. Said in the log with who asked and
 when, never the value. An applied secret is refused by name, until the staged form exists. A value
 given to the mesh rather than made by it is refused as [ADR 0113](../../02-DECISIONS/0113-the-vault-makes-every-secret.md)
 says, with the way out: change it where it lives, then accept the new value.
 **`rotate` is a verb on the controller's seat** ([ADR 0154](../../02-DECISIONS/0154-the-meshs-own-verbs-are-the-controller-seats-tools.md)),
 with the two shapes the mesh has: a pair credential by provision and consuming machine, or an own
 secret by machine, module and name. The console can ask for either.
 Nothing in the catalogue says `taken` yet: the word ships one release ahead of its first use, and the
 first definitions to say it follow once this controller runs.
 *How it is checked:* the manifest form and its refusals; the rotation against a raised store —
 rotates a secret taken at start, refuses an applied one, an undeclared one, an accepted one and an
 unknown name, each in its own words; the verb's two shapes; and, live, a secret rotated through the
 console on a module that reads it at start, the module restarted, and the module working.
 *Done live, 2026-10-01 10:13 UTC:* the search module on the home server, the first definition to say
 `taken: at-start` whose value the mesh had made. Asked through the console; the controller said it was
 rotated and sent the machine; twenty-seven seconds later the secret file carried a new write time, the
 server container had restarted on it, and the module answered. The two secrets filed in the forge's
 report, the automation module's token and admin password, were refused: both had been accepted by hand
 during adoption, and that refusal is the one ADR 0113 asks for — something outside the mesh may hold
 an accepted value, so replacing it is a person's act. Modules whose source is pinned to a commit are
 not rebuilt by a merge; their new definition was registered by asking for a build of main through the
 console, which since [issue 176](../176-the-consoles-build-tool-neither-waits-nor-registers/00-report.md)
 registers what it hears.
 ## Open — the applied form
 The staged rotation ADR 0114 decided for an applied secret is not built: the vault delivering the
 new value beside the current one, the module's own code switching the backend and confirming, and
 only then the new value current. It needs a word in the module's protocol for *confirm*, and it is
 the form the identity provider's administrator and every database's superuser need. The request's
 second half — re-issuing a pair credential through the provider's own code rather than by re-minting
 and pushing — is the same shape from the provider's side, and sits with it.

 # 181 — An assignment does not record which provider answers it
 ## What was observed
 Planning ace's modules that need a database (baserow, letta, n8n, and the apps using ace's
 predecessor postgres). The operator's model — and ADR 0110's — is that **an assignment states where
 each of its requirements is answered from**: gitea's assignment on novox says its `postgres-database`
 comes from novox; an app assigned to ace says whether its database comes from ace or from novox.
 The mesh holds no such statement for any assignment. Read on novox (2026-09-30):
 ```
 select … from provision_pin;   -- 0 rows
 ```
 Every requirement in the mesh resolves implicitly, each time, by ADR 0084's order (a pin, then the
 provider on the consumer's own node, then the only provider).
 ## What was decided, and what exists
 [ADR 0110](../../02-DECISIONS/0110-a-seat-is-a-module-assignment-from-a-closed-set.md):
 > Where several remain and none is local, **a person chooses when the module is assigned**.
 > Assignment lists the candidates, with the holder of a seat that delivers the provision suggested
 > first, and records the answer on the assignment as its pin. Without an answer the module is not
 > assigned.
 What the control plane implements:
 | decided | implemented |
 |---|---|
 | the answer is recorded **on the assignment** | `provision_pin` is keyed `(node, name)` — one answer per machine per provision, shared by every module on it |
 | chosen **at assignment** | `assign <node> <module>` takes no provider; `pin <node> <provision> <from-node>` is a separate command |
 | an assignment may be answered from its own machine (gitea ← novox) | `pin` refuses a machine pinning to itself ("does not need saying") |
 | every assignment has an answer | none recorded; resolution guesses the same answer every time |
 ## Consequence
 Nothing is wrong *today* — with one postgres provider, every guess is the intended answer. But the
 answer is not a fact anyone stated, so:
 - **it changes silently** the day a second provider appears (e.g. a postgres assigned on ace): every
  unpinned consumer re-resolves — a consumer on ace moves from novox's database to an empty one on ace
  at the next push, which is data a module stops seeing without anything saying so;
 - two modules on one machine cannot take one provision from different providers;
 - a person reading an assignment cannot see where its data lives.
 ## What would be right
 ADR 0110 as written: `assign` records, per requirement, the node that answers it (its own node
 included), offering the candidates and refusing an assignment without an answer where several exist;
 the per-machine `provision_pin` becomes a per-assignment record, with existing assignments backfilled
 from what they resolve to now so nothing moves.

 # 182 — A tool call reaches whichever instance answers first, and a claimed seat's verbs are served by nobody
 ## What was observed
 Asked how to list the databases of the store on one machine, the mesh had no answer. A module's tools
 are served on one subject per module, `mesh.mod.<module>.tool.<name>`, and every instance of the
 module joins one queue group on it, so a call to the database engine's tool while it runs on two
 machines reaches whichever answered first, and the answer does not say which. There is no way to ask
 the instance on one machine. The console lists the tool once and offers no machine.
 And the seat half was missing too. Design 33 §3 says holding a seat means serving its tools, and
 ADR 0154 built that for the controller's own seat alone. A module that holds a seat — the database
 engine on the control node holding `mesh-store` — served none of the seat's verbs, because no seat
 but the controller's declares any and no runtime knew which seats its module claimed.
 ## Why this is here
 Both are the same omission: the tool surface was built as if every module ran on one machine and
 held no seat. A queue group is the right default for a stateless module answering anywhere, and the
 wrong only choice for a module whose instances are different things — two stores with different
 databases. The architecture had the distinction: a module is a thing that runs on machines, a seat is
 a role one of them holds. The tool surface did not carry it.
 ## Resolved, 2026-10-01
 [ADR 0159](../../02-DECISIONS/0159-a-tool-call-names-the-machine-and-a-holder-serves-its-seats-verbs.md).
 Every instance serves its module's subject twice: in the queue group as before, and with its own
 machine as the subject's last token. `<module>.<tool>@<node>` reaches one machine's instance; the
 console lists `node` on every module tool and puts it in the subject, never in the module's
 arguments; every answer carries the machine that gave it, and the console appends it as its own line.
 The grant for a tool covers both subjects.
 A holder's runtime serves its seat's verbs: the credential the mesh writes names the seats the module
 claims and the verbs each promises, the runtime serves each verb with the module's tool of the same
 name on the seat's own subject, flat for a mesh seat and with the machine for a node-scoped one, and
 the bus admits the subscription only where the module holds the seat. The store seat's first verbs
 and the database engine's tools for them are the catalogue's next step, recorded in the decision.
 *How it is checked:* against a real bus, a module on two machines answers each by name and says who
 answered when unnamed, and a claimant answers a seat's verb on the seat's subject; the console lists
 `node` on a module's tool and not on a seat's; the grant for a tool covers both subjects; and, live,
 the store's databases listed from one named machine through the console.

 # 183 — The controller could not publish the memberships it issued
 ## What was observed
 The controller release that issues a membership per assignment ([ADR 0160](../../02-DECISIONS/0160-the-mesh-issues-an-assignments-subjects-and-a-runtime-serves-what-it-is-issued.md))
 rolled onto the control node. After its first push the controller's log said, once:
 ```
 nats: permissions violation: Permissions Violation for Publish to "mesh.assignment.<node>.<module>"
 ```
 No membership reached the assignments stream. Nothing else changed: every runtime kept serving the
 shape it derives for itself, which is what the decision says happens while no membership is issued,
 and so the mesh looked healthy while the whole new mechanism was inert.
 ## Why this is here
 The controller composes every account's grant, its own included, and its own grant named the
 control, node and JetStream subjects and not the assignments it alone issues. A grant composed by its
 holder is checked by nothing but the server at publish time, and a refused publish is one log line
 that nothing reads. The fallback that makes the roll-out safe is the same thing that makes this
 failure silent.
 ## Resolved, 2026-10-01
 The controller's grant names `mesh.assignment.>`; the broker golden changed by that one line. A
 grant composed by its holder arrives late — the broker node is pushed after the controller rolls —
 so the roll-out is merge, push the broker node, then any push issues memberships.
 The refusal had a second consequence: published with the daemon's own context, the refused
 membership was waited on for ever and the controller went deaf —
 [issue 185](../185-a-refused-membership-publish-stops-the-controller/00-report.md).
 *How it is checked:* the broker golden carries the allow line; live, a runtime's log after the next
 push says it was issued a membership rather than that none exists.

 # 184 — A merge announcement blocks the controller's receive loop
 ## What was observed
 The controller restarted at 12:53:32Z on 2026-10-01 and heard, among its first messages, a merge
 announcement for the catalogue that touched some forty modules. Until 13:17:16Z — twenty-four
 minutes — it took nothing else in: build outcomes that the build machine had announced and that
 the console's `builds` log showed as done sat unrecorded, so `builds` listed none of them and the
 modules stayed at their old versions; the node heartbeats were dropped by the bus as a slow consumer
 on `mesh.control.*.alive`, twice. When the merge handler returned, everything queued arrived at once
 and was taken in within a second.
 ## Why this is here
 The receive loop acts on one message at a time, which is the right discipline for a store the
 controller must write in order. Acting on a merge means asking builds and waiting for each outcome,
 minutes of work, and that wait happens inside the loop that would otherwise be hearing the outcomes
 of everything else. The bus keeps the merge message alive while the work runs — the fix for the
 earlier repeated-merge fault — so nothing is lost and nothing is redelivered, and nothing is heard
 either. The design permits the controller to go deaf for as long as a merge takes to build, and no
 status says so: the mesh reads as quiet, builds read as missing, and heartbeats read as a slow
 machine.
 ## Also seen, 2026-10-01 evening
 The handler's work is lost when the controller is replaced while it runs. The runtime image's merge
 at 14:22Z was taken by a controller that rolled forty seconds later, after asking the image's own
 build and before asking the forty-two that stand on it. The announcement was redelivered to the new
 controller, which judged it history — the source had been looked at after the merge — and said
 "nothing the mesh holds reads it". The dependents were asked by hand. Whatever shape the fix takes,
 the work a merge implies has to be recorded as asked, not held in the handler's stack.
 ## What a fix needs to decide
 Whether a merge is work the loop dispatches and returns from — the builds asked, the outcomes taken
 in by the same `Built` handler every other outcome uses, since the stream already delivers them —
 or whether the loop runs more than one handler at a time with the store's ordering kept for the
 kinds that need it. The first is smaller and keeps one ordering. Either way, a controller that is
 busy should say so where `status` is read.
 *How this would be checked:* a controller test where a merge announcement that asks a slow build
 and a build outcome for another module arrive together, and the outcome is recorded before the
 build finishes; live, the controller's log during the next catalogue merge shows registrations
 interleaved with the merge's own.
 ## Decided, 2026-10-01
 [ADR 0162](../../02-DECISIONS/0162-a-merge-produces-a-tiered-plan-the-mesh-keeps.md): a merge
 produces a tiered plan the store keeps; the handler asks the first tier and returns; outcomes advance
 the plan; a controller replaced mid-plan resumes it. The loop is never held by a build again.
 ## Resolved, 2026-10-01 evening
 Since the controller holding ADR 0162's plan rolled, a merge announcement is handled in
 milliseconds: the plan is written, the first tier asked, the loop free. The builds the merge
 implies are asked from the store's record, tier by tier, so a controller replaced mid-plan resumes
 it rather than losing it. The first live merge under it (a controller change) is the proof the
 decision's table asks for; its tiers are read with `plans`.
 *How it is checked:* the plan tests in mesh-controller; live, `plans` after a merge and the loop's
 log taking reports in while the plan builds.

 # 185 — A refused membership publish stops the controller
 ## What was observed
 At 13:17:22Z on 2026-10-01 the controller, acting on a build it had just taken in, sent the control
 node a declaration and then issued that node's memberships. The server refused the first publish
 ([issue 183](../183-the-controller-could-not-publish-the-memberships-it-issued/00-report.md)). From
 that second on the controller heard nothing: the control node applied the declaration at 13:18 and
 its report was never taken; two merges announced by the forge were not built; the heartbeats were
 dropped by the bus as a slow consumer; the console's `builds` showed nothing new while the build
 machine's own log showed builds done. The controller's seat verbs still answered, so `status` read
 as quiet. It stayed so until the controller was replaced.
 ## Why this is here
 A stream publish waits for its acknowledgement for as long as its context lives, and a publish the
 server refuses is never acknowledged. The membership was published with the daemon's own context,
 which lives as long as the daemon, from inside the one loop that hears everything else. Two
 mechanisms built the day before met badly: the receive loop that acts on one message at a time
 ([issue 184](../184-a-merge-announcement-blocks-the-controllers-receive-loop/00-report.md)) and a
 publish that could wait for ever. The design let a refusal that is said in one log line become a
 controller that is deaf with no sign of it.
 ## Resolved, 2026-10-01
 Issuing one membership is bounded to ten seconds, and a push counts the memberships it could not
 issue, names the first failure, and stands: the declarations were sent and recorded before it, and
 every runtime without a membership serves the shape it derives
 ([ADR 0160](../../02-DECISIONS/0160-the-mesh-issues-an-assignments-subjects-and-a-runtime-serves-what-it-is-issued.md)).
 The live controller was replaced by hand: the fix was built from the CLI inside the running
 container with a wait; the stuck daemon held the control node's advisory lock in the store, so the
 container was restarted to release it; the control node was pushed from the CLI and took the fixed
 controller; a second push from the fixed controller carried the broker's grant, and the broker
 reloaded. The push command itself issued no memberships — only the roll-out path did — which is
 mesh-controller PR 191.
 *How it is checked:* a link test publishes a membership to a server that refuses it and returns
 within the bound; live, the controller's log after a push names the memberships it issued or could
 not, and keeps taking reports either way.

 # 186 — A release across repositories is an order in a person's head, and a build is a line in a queue nobody keeps
 ## What was observed
 On 2026-10-01 one decision (ADR 0161) was built as three pull requests in three repositories that
 must land in order: the controller first, so the seat exists and a report's profile is kept; the host
 second, so every machine reports the capability; the catalogue last, so a claim names a seat that
 exists and a holder is not refused on every machine. That order is written in a work-order file and
 in the pull requests' descriptions. The mesh holds none of it. A merge is handled as a merge: build
 the modules whose recorded source is that repository, record what came back. Nothing says what the
 mesh should end up as, and nothing checks whether it got there.
 The same day showed what a build is. The build machine takes asks from an in-memory queue; when it
 was itself rebuilt in the middle of a wave of forty-three asks, the machine rolled, the new one
 started with an empty queue, and forty asks were gone without a word — the wave read "one of
 forty-three" for two hours. A merge announcement that asks forty builds waits for them inside the
 controller's one receive loop ([issue 184](../184-a-merge-announcement-blocks-the-controllers-receive-loop/00-report.md)).
 "Did everything I asked for succeed" was answered by counting lines in two containers' logs.
 ## Why this is here
 Every single step is sound: a build is reproducible, a push composes a machine from the store as it
 is, memberships are last-per-subject, so the mesh converges to the right state once every build is
 recorded and every machine pushed. What is missing is the whole: the mesh has no durable account of
 work it has asked for and no account of the state a release is aiming at, so the two faults that
 matter most to an operator — work silently lost, and a dependency between repositories merged in
 the wrong order — are detected by nobody. The rule that a manifest word ships one release ahead of
 its use is a discipline a person keeps, and a person kept it by hand eleven times this week.
 ## What a decision would settle
 - Whether a build ask is a durable message on the bus (a work queue the build machine takes from and
  acknowledges, as the build outcome already is an event), so a restarted builder resumes rather
  than forgets, and `builds` can list what is asked and not yet built.
 - Whether a release across repositories is a thing the mesh records — a set of commits that belong
  together with the order they land in — so that a merge out of order is refused or held rather than
  built, and `status` can say what a release still waits for.
 - What the smallest honest surface is in the meantime: at least `builds` listing the asked and the
  running beside the built, so a person polling logs becomes a person reading one table.
 ## Located, 2026-10-01 evening
 Two of the three faults turned out to be mechanism, and are fixed; the third stands as the decision
 this report asks for.
 - **The queue was durable; the delivery was not.** A build ask is a message in the seat's work-queue
  stream and survives a builder restart. What lost forty-three asks twice was the worker consumer:
  with the server's default of many deliveries in flight, every ask behind the one being built was
  handed over at once, left unacknowledged for the length of the build, redelivered after the ack
  wait, and dropped after the fifth time. The builder's log shows the survivors in redelivery order.
  Fixed by mesh-controller PR 194: one in flight, and a running build says it is still working.
 - **A merge rebuilt what it changed and not what stood on it.** The relation existed in the store
  and only the explicit `build --on` read it. Fixed by mesh-controller PR 193: a merge takes every
  module standing on what moved, in base order.
 - **A release across repositories is still an order in a person's head.** That is the decision.
 *How this would be checked:* a builder restarted between an ask and its build still builds it; a
 merge of a dependent repository before its prerequisite is held and named; `builds` lists asked,
 running and built.
 ## Decided, 2026-10-01
 The third fault is answered by [ADR 0162](../../02-DECISIONS/0162-a-merge-produces-a-tiered-plan-the-mesh-keeps.md):
 a release across repositories is a plan whose dependency edges cross repositories, sorted into
 tiers and deployed tier by tier, read in `status`. The order a person kept is the order the tiers
 give.

 # 187 — The mesh tells nobody when it stops working
 ## What was observed
 One day, 2026-10-01, and five faults, each found by a person reading a container's log hours after
 it began, and each invisible to every surface the mesh offers:
 - The controller's receive loop was blocked for twenty-four minutes by a merge handler, then for
  nineteen minutes by a publish the bus had refused ([184](../184-a-merge-announcement-blocks-the-controllers-receive-loop/00-report.md),
  [185](../185-a-refused-membership-publish-stops-the-controller/00-report.md)). Throughout, `status`
  answered and read as quiet, `builds` listed what it had, the console answered every tool. Nothing
  said *the controller has taken nothing in since 13:17*.
 - The build machine dropped twenty-six of forty-three asks ([186](../186-a-release-across-repositories-is-an-order-in-a-persons-head/00-report.md)).
  Nothing counts asks against builds; the queue read as empty; the loss was inferred two hours later
  from a wave that would not finish.
 - The controller's own grant refused every membership it published ([183](../183-the-controller-could-not-publish-the-memberships-it-issued/00-report.md)),
  and then every module on the new runtime was refused its one read of the stream. Both were one
  `Publish Violation` line each in the bus's log, which nothing in the mesh reads.
 - The bus dropped the machines' heartbeats as a slow consumer, twice, and said so to the controller's
  log only.
 In every case the designed fallback held — runtimes served the derived shape, a push later carried
 what an earlier one had not — which is why the mesh kept working and why nobody was told.
 One more the same evening: the laptop applied a declaration and logged *applied, and could not tell
 the mesh: reporting: context canceled*. The report was not retried; the mesh went on believing the
 machine's previous state until the next push, and nothing on either side counted the loss.
 ## Why this is here
 The repository's own rule is that a rule states how it is checked, and every record here does. But
 the checks are tests and `status`, both asked by a person. The mesh has no account of its own
 liveness: whether the controller is hearing, whether the queue is moving, whether the bus is
 refusing what the mesh composed, how old each machine's last report is. A fault that leaves the
 fallbacks standing is a fault nobody learns about until it compounds, and today three of them
 compounded into an evening of reading logs. This is the design permitting a failure to be silent,
 which is the first line of what belongs here.
 ## What a decision would settle
 - **What the mesh observes about itself.** At least: the receive loop's last message taken and its
  age; asks against builds, with the oldest unbuilt ask's age; publishes the bus refused and
  subscriptions it dropped, read from the bus rather than from a log; each machine's last report
  and heartbeat age; a module whose runtime says it serves the derived shape.
 - **Where it says so.** As events on the bus under the controller's seat, so a log viewer and a
  notifier are consumers and not special cases; and in `status`, which must go red for any of them
  rather than listing only machines that are behind.
 - **Who is told.** A channel a person actually reads — the mesh already has modules that send
  mail and messages — chosen once, with a rule for what interrupts a person and what waits for
  `status`.
 - **What is not a monitor.** Nothing here is a dashboard product the mesh adopts; it is the mesh
  stating facts about itself, the way [ADR 0134](../../02-DECISIONS/0134-the-mesh-says-what-it-applied.md)
  made it state what it did.
 *How this would be checked:* a controller test where the loop is held and `status` goes red
 naming the age; a test where an ask is unbuilt past a bound and `builds` says so; live, the next
 fault of today's kinds reaches a person before a person reaches the log.

 # 188 — A refusal inside "who is on the network" drops a machine silently, and every symptom points elsewhere
 ## What was observed
 At 15:28Z on 2026-10-01 the controller rolled to a build that refuses a machine with two modules
 answering one provision and no pin naming which (mesh-controller 195). The control node had two
 issuers of `acme-ca`. From that moment every plan of the control node failed with *step-ca has a
 content that says `${machine:at}`, and this machine says mesh-range or name*; `seats` listed every
 seat as unheld; the build machine refused the builder's and the proxy's builds with *no clone base
 for that seat — nothing holds it*; and the roll-out of the next controller was refused with the
 `${machine:at}` words. Not one of those names the cause. It was found by running the previous image
 as a one-shot beside the current one and reading the difference, forty minutes later.
 ## Why this is here
 `onTheNetwork` decides which machines have an address by resolving each one, unchecked, and
 *skipping* any whose resolution errs. A machine skipped there has no `at`, so its own plan fails on
 the first placeholder that needs one, in another module's words; everything held on it reads as
 unheld; everything built from it cannot be built. The design lets one refusal become four unrelated
 symptoms and no sentence about the refusal itself. It is the same shape as
 [issue 187](../187-the-mesh-tells-nobody-when-it-stops-working/00-report.md): a fault that is swallowed
 where it happens and discovered where it hurts.
 ## What a fix needs
 - A machine whose resolution refuses is said, by `onTheNetwork`'s caller or in `status`: *the
  control node does not resolve: more than one module provides acme-ca; pin one* — the resolver's
  own words, which exist and were dropped.
 - A refusal that a release introduces for a machine already converged — a new rule the stored
  state does not meet — must not be silent at the roll either; the controller's prepare or first
  resolution after a roll should name every machine it now refuses.
 *How this would be checked:* a controller test where one machine's unchecked resolution refuses:
 `status` names the machine and the refusal, and the other machines keep their addresses.
 ## Resolved in the live mesh, 2026-10-01
 Two faults, one on top of the other. The refusal was mesh-controller 195's new rule — two modules
 answering one provision on one machine need a pin — which its author hotfixed for the first pass
 (196). The second pass of "the rest of the mesh" resolves every machine *without its pins*, so the
 control node, pinned or not, was refused there and vanished: every seat it holds read as unheld,
 the builder's and the proxy's builds were refused for want of the git seat's clone base, the
 roll-out of the next controller was refused, and the first tiered plan failed at its first tier.
 Found by a diagnostic build counting what each machine yielded. Fixed by mesh-controller PR
 `fix/a-machine-not-on-the-network-is-said`: each machine is resolved with its own pins, and a machine
 left out is named with the resolver's words in both places. The pin itself (`step-ca`, the issuer
 the proxy already had) was made by hand and stands.
 ## Resolved, 2026-10-01 evening
 The controller holding the fix was rolled onto the control node by the operator and a colleague
 (the running one could not roll itself); after it every seat read as held again, a build asked
 through the git seat worked, all four machines resolved and pushed. The line naming a dropped
 machine spoke once too often — in the per-machine view, where the others are resolved without the
 planned machine's offers and may fail by design — and is quiet there since mesh-controller PR 200.
