jochen 6e306fcb4c To-be 40: building the operator's agent and its licence manager as work packages
Designs 36 and 39 say what is built; this says in which order and what proves each step, in the
shape to-be 38 gave the operator's machine. Seven packages: the operator states the facts (accounts,
roles, licences); the console provides its endpoint; the licence manager and the agent module are
built and unit-tested in parallel; the manager goes live on the control node; the agent on one
workstation, with the switch and the predecessor's files removed as the proof of the whole; then the
rest of the nodes and the retirement of the two catalogue modules built on the old placement. The
live proofs wait for to-be 38's WP3, because both modules' tools run in the node's tool runtime
(ADR 0175) and a per-module tool container would rebuild what that record retires.

jochen 7b1dabbce0 The operator's agent and its licence manager are modules: ADR 0181–0183, to-be 36 and 39
The predecessor's agent module was retired and its six files stayed on both workstations telling
every session to use tools that no longer exist. This is its successor's design, revised during
review on the operator's directions: the host is module-agnostic, the controller has no part, and a
real licence manager hands out the correct licence in every situation.

- ADR 0181 (reconstructed): the operator account is a node fact stated by the operator; the home is
  derived unless stated; a resource may be placed under it owned by the account; a node with no
  account refuses one. What the controller shipped on 2026-09-27 without a record.
- ADR 0182: inside a home the module owns the directory and the files it places, writes into the
  tool's own files for its few keys, never declares a credential's content, and holds everything
  else as found; a predecessor's leftovers are the operator's to remove once.
- ADR 0183: claude-licence-manager holds the mesh seat anthropic-licence-manager and owns the
  Anthropic licences, grants (encrypted with a key the vault made for it), bindings per touchpoint,
  usage and audit; one rotation source under a lease; a token travels module to module sealed to
  each node's module key on request/reply, never as an event; the agent module alone writes what
  the agent reads; the host delivers package and state and knows nothing else. A bounded exception
  to ADR 0113; dated mechanism notes on ADR 0050 and 0113.
- To-be 36 (claude-code): the mesh's part of the agent's configuration lives in the agent's
  machine-wide managed directory, owned whole by the module and written by its code; nothing under
  the home but the credentials file of a subscription licence; the API-key licence through the
  key-helper; the console as a node-scoped provision (to-be 34 amended); MCP servers as settings
  with an mcp_configure tool; one agent directory per machine shared by every session.
- To-be 39 (claude-licence-manager): store, the two licence kinds, keeping a grant alive, the
  hand-over, who gets which licence with the predecessor's fallbacks, adoption with the identity
  guard, the seat's verbs.

Numbers taken across main and every open branch at the time of the merge; to-be 14, 29 and 34
carry dated notes; the glossary gains "operator account".

# 181. The operator account is a node fact, and a home is a placement root
*Reconstructed. The controller shipped this on 2026-09-27 and
[to-be 29](../03-DESIGN/01-to-be/29-a-node-has-operator-accounts.md) recorded it as built without a
decision behind it. This record states what was decided, from the code and the design, and adds the
two rules the code left implicit — what an empty account means for a module, and that the account is
stated rather than discovered. Written 2026-10-02.*
## Context
[ADR 0112](0112-a-module-definition-names-no-node-mesh-or-path.md) took every host path out of a
module definition and gave a module's *system* data a place: a directory the mesh resolves under the
node's root, owned by the module. It said nothing about the other half of a filesystem — the files
that belong under a person's home and are owned by that person. The predecessor wrote several of
those: the ssh client configuration, the shell's configuration, an agent's instruction files. It knew
whose home it was writing into because each of its node records carried a login name. The mesh took
the machine facts over and dropped the human one.
The loss was found the ordinary way: `ssh <node>` logged into the home-server under the workstation's
own login name, because nothing in the mesh said the home-server's account was a different one
([to-be 29](../03-DESIGN/01-to-be/29-a-node-has-operator-accounts.md),
[issue 172](../04-ISSUES/172-the-ssh-client-block-matches-one-spelling-of-a-machine/00-report.md)).
What the controller does since 2026-09-27: a node record carries an operator account and, optionally,
its home; the account and its home are machine facts a definition may name in a resource's path, owner
and content; a roster file may say it lives under the home, and is then rendered per node, placed under
that node's account's home, owned by the account, and left out on a node with no account. On
2026-10-02 **all four nodes of the live mesh carry an empty account**: the fact exists and nobody has
stated it, so no home-scoped resource can land anywhere yet.
## Considered Options
1. **The definition names the login.** `owner: <name>` in the module. Rejected: it is the installation
written into a definition, which ADR 0112 forbids and
[ADR 0155](0155-a-definition-names-no-installation-and-how-that-is-checked.md) checks for, and it is
wrong on the first machine whose login differs — which is exactly the machine that surfaced this.
2. **The host discovers the account.** The first non-system user, or whoever ran the enrolment.
Rejected: a guess. A shared machine has several people on it, a server may have none, and a host
deciding whose files these are is a decision the mesh then cannot see, state or correct.
3. **The account is a fact the operator states on the node record, and the home is derived from it
unless stated.** Chosen.
## Decision
**A node has an operator account: the login name of the person who works on it.** It is stated by the
operator on the node record, the way a node's address or mode is held there, and it is empty for a
machine nobody logs into. Empty is a real state, not a missing value. The mesh holds the fact because
everything below derives from it, and because it is precisely the fact that was lost when the
predecessor's records were not carried over.
**The account's home is derived unless stated.** The superuser's home for the superuser, the
distribution's conventional per-user home otherwise; a node whose account lives elsewhere states its
home. One place computes the default, so a fact and the record cannot disagree about it.
**A resource may be placed under the home, owned by the account.** This is ADR 0112's move one level
over: as a module's system directory is resolved under the node's root, a file under a person's home is
resolved against the account's home, and owned by the account rather than by root or a module's own
account. A definition names the account and its home as machine facts, never as a path; a roster fact
may say it is a home file and is then placed and owned the same way. The controller resolves both at
composition, and the host chowns what it creates.
**A node with no account cannot carry a home-scoped resource, and says so.** A roster fact that lives
under the home is left out of that node's declaration rather than written to nowhere. A resource naming
the account fact on such a node is refused at composition, naming the fact the machine does not have.
A module that writes a person's files is thereby unassignable to a machine with no person on it, which
is the right refusal.
**One account per node is what this record decides.** Several people on one machine is left open, with
the constraint that allowing it must not force the common case — one workstation, one person — to name
anything.
## Consequences
- **The operator states the account before any home-scoped module lands.** Today none is stated, so the
first assignment of such a module begins with four node records.
- The roster carries each node's account, so a composed ssh configuration logs in as the right person
on every machine — the gap that surfaced this, closed by the same fact.
- A family of modules becomes writable: everything the predecessor placed under a home — ssh client,
shell, the agent's instruction files — is now a module naming a fact rather than a path
([to-be 29 §2](../03-DESIGN/01-to-be/29-a-node-has-operator-accounts.md)).
- **What got harder:** a definition cannot say "my user's home" without the mesh knowing who the user
is, so a module of this family is refused on a freshly enrolled machine until a person is named on
it. That is a prompt, not an obstacle.
- **Not decided here:** several accounts per node; a service unit running as the account rather than
as root or a module; a one-off step run as the account. Each is a record of its own.
## How it is checked
| Rule | Checked by |
|---|---|
| A resource's path and owner resolve the account and its home | controller tests on machine-fact resolution: a file naming the account facts lands under the account's home, owned by the account |
| The home is derived unless stated | a controller test: the superuser's home for the superuser, the conventional home otherwise, the stated home when one is stored |
| A home roster fact is left out on a node with no account | a controller test on roster composition: the file is absent from that node's declaration and present on a node with an account |
| A resource naming the account on a node with no account is refused by name | a controller test on machine-fact resolution: the refusal names `account` and lists the facts the machine does have |
| No definition names a home path | ADR 0112's catalogue test on host paths, which a `/home` or `/root` literal fails |

# 182. Inside a home, the mesh owns the directory and the files it places, writes into the tool's own files, and holds everything else as found
## Context
[ADR 0181](0181-the-operator-account-is-a-node-fact-and-a-home-is-a-placement-root.md) lets a module
place files under a person's home. A home is unlike any directory the mesh has written into so far:
it is shared with the person, and with every program the person runs. The agent's configuration
directory on the laptop makes the point. On 2026-10-02 it holds thirty entries. The predecessor placed
five of them (an instruction file, a conventions rule, a settings file it merged into, two skills); a
sibling module placed a sixth (the node's identity rule). The agent itself writes the other
twenty-four: its settings, its credentials, its history, the memory of every project it has worked in,
its plugins, its session logs. Several of those are what [to-be 15](../03-DESIGN/01-to-be/15-the-agent-session.md)
calls memory *written by the session itself and declared by nobody*: a mechanism that regenerated the
directory would erase a season of it, silently, while reporting success.
The predecessor's own module recorded the hazard in the other direction. Its settings file was first
shipped as *replace*, and every `/model` choice a person made inside a session was reverted to the
template's value on the next synchronisation — on every node, indefinitely, with no indication why. It
was changed to *merge*, and the comment explaining why is still in its manifest.
**And the generator is gone while its output stayed.** The predecessor was retired from the laptop on
2026-10-01. Its six files are still on both workstations, with their content telling every session to
use tools that no longer exist. Nothing owns them; nothing will ever rewrite or remove them.
[To-be 29 §3](../03-DESIGN/01-to-be/29-a-node-has-operator-accounts.md) drew the line for one directory,
`~/.ssh`: the mesh owns the directory and the files it places; it holds the person's private keys and
personal drop-ins as found. That was argued from the lockout `~/.ssh` can cause. The argument here is
the same shape with a different stake — the person's work rather than the person's way in — and it has
to hold for every directory the family of home-scoped modules will touch, so it is a rule, not a
section.
## Considered Options
1. **The module owns the directory whole**, regenerating it from the definition. Rejected: it destroys
the memory, history and local settings the agent writes for itself, which is the failure to-be 15
names and the predecessor's settings file demonstrated at small scale.
2. **The module owns only the files it names, and nothing about the directory.** Rejected: *owning one
file beside foreign ones is not owning anything* (to-be 29). The directory must exist, with the right
owner and mode, before the tool first runs on a fresh machine; and a credentials file in a
world-readable directory is a credentials file in the wrong directory.
3. **The module owns the directory and the files it places; a file the tool writes for itself is
written into, never over; everything else is held as found.** Chosen.
## Decision
**A home-scoped module owns the directory it declares: its existence, owner and mode.** The host creates
it if absent, owned by the account, and never removes it while it holds anything
([ADR 0030](0030-data-outlives-the-mesh-that-declared-it.md)). Inside it, every path the module touches
is in exactly one of four classes, and **the class is visible in the definition from the shape
declared**, not inferred from what happened to be on disk:
| class | declared as | the host's rule |
|---|---|---|
| **owned** | a file with content, or a roster fact | written whole, regenerated, removed when undeclared; a file found there with no record of the mesh making it is kept once before it is written over ([ADR 0102](0102-the-mesh-writes-into-a-shared-file-never-over-it.md)) |
| **written into** | a file written *into* a structured document | only the keys the definition names are set, every other key is kept, and each set key is given back when undeclared (ADR 0102). The key list is the module's and is short |
| **written by the module's own process** | nothing the host applies: the module's code writes it from what it was handed | the file's content is never a declared file's content, because a declaration travels in the clear on the bus and the host records it; the module's code writes it, owned by the account, atomically. [ADR 0183](0183-the-anthropic-licence-manager-is-a-module-and-hands-tokens-to-the-agent-over-the-bus.md) says how for a credential |
| **found** | nothing | never read, never rewritten, never removed. The person's memory, history, projects, local settings, their own rules and skills |
**A file the tool writes for itself is written into, never over.** The agent's settings file and its
own state file are the tool's; the mesh has one or two facts to state in each. Setting those keys and
nothing else is what lets a person's `/model` choice survive a push, and what lets the mesh's keys be
taken back cleanly when the module goes.
**A predecessor's output is found.** A file placed by a generator that no longer exists is, to the
mesh, a file it has no record of making. Where the successor module keeps the path, declaring it
*adopts* it: the host keeps the original once and writes the mesh's. Where the successor does not keep
the path, the mesh does not remove the file, because it removes nothing it did not make; **the operator
removes it, once**, and the module's definition names those paths in its own documentation so the step
is not forgotten. This is the first instance of the one-off setup step to-be 29 leaves open, and the
rule chosen for it is that it is a person's act, listed, not a module's.
**The rule is the family's.** An ssh client module, a shell module, an agent module each declare their
directory and classify their paths this way. A module that cannot say which class a path is in has not
finished its definition.
## Consequences
- A person's work under their home survives every push and every unassign. The mesh's own files come
and go with the module; the mesh's keys in the tool's files come and go with it; the directory stays.
- **Stale files survive too.** Two workstations keep three predecessor files each until a person removes
them — a visible cost, accepted over a mesh that deletes under a person's home. A module author who
renames one of the mesh's own files has the ordinary path: the old resource id is undeclared and the
host removes what it made ([ADR 0118](0118-undeclaring-gives-a-unit-back-the-state-it-was-found-in.md)).
- A module's definition is longer by a classification, and a reviewer has one more question per path.
That is the point: *which parts are managed must be explicit rather than inferred* (to-be 15).
- **What got harder:** a module cannot seed a person's preference once and leave it. A seeded file
([ADR 0087](0087-a-seeded-file-is-created-once.md)) is the shape for that, and it is available to
this family unchanged; what is refused is a seed the module later wants to change, because what grew
in it is the person's.
## How it is checked
| Rule | Checked by |
|---|---|
| The directory is created owned by the account and kept when the module goes | host tests of a directory resource with an owner (ADR 0051's and 0118's), and the family's lab check below |
| An owned file found with no record is kept once, then written | host tests of ADR 0102's kept-original rule |
| Only the declared keys of a written-into file change, and are given back | host tests of ADR 0102: declared keys set, the rest kept, restored when undeclared |
| Nothing found is touched | the family's lab check: a machine with a seeded home holding a person's file beside a predecessor's; after apply the person's file is byte-identical, the predecessor's is kept as the original, the mesh's keys are set and the person's keys in the same file remain; after unassign the mesh's files are gone, the keys are restored, the person's files are untouched and the directory stands |
| Every path a home-scoped module touches is classified | a catalogue review rule for this family: each path is a directory, a file, a file written into, a secret-and-step, or absent — the first module written to it is [to-be 36](../03-DESIGN/01-to-be/36-the-operators-agent-on-a-machine.md) |

# 183. The Anthropic licence manager is a module holding a seat; it hands each node's agent its token over the bus, sealed; the controller and the host have no part
## Context
**The operator's stance, set on 2026-10-02 and sharpened during the day.** The controller has no part in
the agent module. The host is module-agnostic: it knows no vendor, no agent, no path under a home. The
agent module owns its own files. And there must be a *real* licence manager — a module that doles out
the correct licence in every situation the mesh has: two subscription accounts and one API key today,
used by a person's interactive agent on each workstation, by the mesh's own sessions, and by workers.
**What the predecessor built, read from its code the same day.** Two modules, split after an incident.
A *manager* on exactly one node held every account's full OAuth grant encrypted, rotated each grant
under a per-licence lease on a cadence and an expiry floor, published each rotation over its bus with
the tokens encrypted, collected the vendor's usage figures per licence, and alerted once a day on
repeated failure or on a refresh token within three days of its own expiry. A *consumer* on every node
was the single writer of the agent's credentials file: it applied a published rotation, stripped the
refresh token so a node could never rotate, pulled when stale, refused a stale grant by comparing
expiries within one lineage, and mirrored a local login back to the manager only after checking the
account's identity against the licence's record — because an unchecked mirror had once written one
account's grant into another's row and published it mesh-wide. Three **touchpoints** with fallbacks: the
node's interactive agent; the mesh's own sessions on the node, falling back to the node's licence; a
worker's own account, falling back to the node's, and refusing to spawn when assigned a licence that
could not be served. The split exists because four nodes refreshing one grant destroyed it: an OAuth
refresh rotates the refresh token, and the predecessor's own code records both that a reused token
killed a licence and that a malformed client id was once misdiagnosed as the same fault. **Whether a
refresh token is single-use is not documented by the vendor**; the predecessor treated it as so, and
this record keeps one rotation source for that reason while leaving the fact to be measured.
**What the mesh has.** [ADR 0050](0050-model-access-is-vendor-agnostic.md) put a per-vendor adapter
inside the controller's licences context, with the carve-out that the manager node holds the refresh
token readably; the catalogue has a manager and a consumer module built on it, assigned to nothing. The
controller's licence commands are not seat verbs and cannot be asked for through the console
([to-be 33](../03-DESIGN/01-to-be/33-the-tools-the-mesh-answers.md)). `model-access` is a vendor-blind
provision ([ADR 0024](0024-model-access-is-a-provision.md)), and the operator's judgement is that the
agent is not a vendor-blind consumer: it is coupled to an Anthropic subscription grant and nothing else,
so a name that hides the vendor misdescribes the coupling
([ADR 0027](0027-a-provision-names-what-the-consumer-is-coupled-to.md)).
**The bus's rule for a secret** ([to-be 32 §10](../03-DESIGN/01-to-be/32-what-a-module-declares.md)): the
bus is not trusted with one; a secret travels sealed to its recipient, on core request/reply, never
through a stream that persists it.
## Considered Options
1. **Keep the lifecycle in the controller** ([ADR 0050](0050-model-access-is-vendor-agnostic.md) as
built), and make the agent module a consumer of `model-access` delivered by the host as a sealed
file. Rejected by the operator: the controller and the host would both carry a part of an
Anthropic-specific mechanism, and the agent's coupling is misnamed.
2. **The manager delivers each short-lived token through the vault**, as a backend-issued secret the
vault provides to each consumer ([ADR 0113](0113-the-vault-makes-every-secret.md)). Rejected: every
hourly rotation becomes a vault delivery, a composition and a push to every node, and the host
ends up writing a vendor's credential as a file — the module-agnostic host, carrying a vendor's
traffic.
3. **A seat-holding manager module that talks to the agent module on every node over the bus.**
Chosen.
## Decision
**The Anthropic licence manager is a module, `claude-licence-manager`, holding the mesh-scoped seat
`anthropic-licence-manager`.** The seat's contract is the licence verbs: list the licences and their
health, list the bindings, bind or switch a consumer, release one, refresh now, read usage, adopt a
grant, register a node's key, answer a consumer's current token. One holder, on a node the operator
assigns, is what makes rotation happen once ([ADR 0126](0126-a-module-declares-its-own-seats.md),
[ADR 0132](0132-a-seat-carries-the-tools-its-holder-must-serve.md)). The seat is named for the vendor,
because what it manages is one vendor's grants and nothing else is coupled to it. The vendor-blind
`model-access` provision stands for the consumers that do not care which vendor answers; the agent is
not among them.
**The manager owns the licences.** The records, the grants, the bindings per touchpoint, the usage
readings and the audit of every switch live in the manager's own store, not in the controller's
licences context, which keeps only what it already serves to vendor-blind consumers. The manager is the
one rotation source: it alone calls the vendor's token endpoint, under a lease per licence, on an expiry
floor and a cadence it declares as a setting.
**The long-lived grants are encrypted at rest with a key the vault made for the manager.** The vault
keeps custody of that one key as the manager's own secret ([ADR 0113](0113-the-vault-makes-every-secret.md));
the grants themselves — a refresh token per subscription account, the API key — are the manager's
rows, readable only by it. This is [ADR 0050](0050-model-access-is-vendor-agnostic.md)'s carve-out,
moved with the manager: *one module, one node, the long-lived grants only.*
**The short-lived tokens travel module to module, sealed, on request/reply.** The agent module on each
node makes a keypair of its own when it first runs — a private key made where it is used, never leaving
([ADR 0113](0113-the-vault-makes-every-secret.md)) — and registers its public half with the seat. The
manager hands a node its token by calling that node's agent module (`<module>.<tool>@<node>`,
[ADR 0159](0159-a-tool-call-names-the-machine-and-a-holder-serves-its-seats-verbs.md)) with the token
sealed to that key, and the module answers *applied* or *refused* and why. An agent module that starts,
or finds its token near expiry, asks the seat for its current token the same way. **A token is never
published as an event**: what the manager emits — rotated, switched, failing, usage read — names the
licence and nothing secret, and the audit logger records it. This is a second channel for a secret
beside the vault's, and it is bounded as 0050's carve-out is: this vendor, tokens that live hours, sealed
to one recipient, request/reply only.
**The agent module alone writes what the agent reads.** For a subscription licence it writes the
agent's credentials file under the operator's home, as the operator, access-token-only, atomically. For
the API-key licence it serves the key through the agent's own key-helper setting, so nothing is written
under the home at all. For the mesh's own sessions and workers on that node, it is the local source of
their token. **The host delivers the module's package and its state directory and knows nothing else**:
no path under the home, no vendor, no file shape.
**A binding is explicit, and a switch is a reaction.** Every consumer — a node's interactive agent, the
mesh's session on a node, a worker — is bound to a licence by the operator through the seat's verb, with
the predecessor's fallbacks: a session inherits its node's licence, a worker inherits its node's, and a
worker assigned a licence that cannot be served is refused rather than lent another. Exhaustion is
observed and warned about once per crossing of a declared threshold; moving a consumer to another
licence is a person's act through the seat's verb, as [ADR 0024](0024-model-access-is-a-provision.md)
says, and the declaration language grows no conditional. An automated policy is not decided here.
**A login is attributed only to the account it belongs to.** When a person logs in on a node, the
agent module reads the account's identity from the agent's own state and offers the grant to the
manager sealed to the manager's key; the manager adopts it only when the identity matches the licence
the node is bound to, and refuses with a notification otherwise.
## Consequences
- One module decides which licence every consumer gets, one module writes what each agent reads, and
neither the controller nor the host carries a word of the vendor.
- **A second sealed channel exists** beside the vault's, bounded as stated. A record that widens it to
another vendor or a longer-lived secret is a new decision, not an application of this one.
- The catalogue's `anthropic-manager` and `anthropic-consumer` modules, built on ADR 0050's placement,
are retired once the manager runs; the controller's licences context stops holding Anthropic licences.
- The console lists the seat's verbs, so a person switches a licence in a sentence, and the controller
gains no `licence` verb.
- **What got harder:** a manager that is down leaves every node on its last token until it expires;
the agent module keeps the last token and says so. And a node whose agent module has not registered
its key cannot be handed a token, which the manager reports by name.
- Every interactive session on a machine shares the node's one agent directory, and so its licence;
twenty sessions share it as one does. A consumer with a licence of its own on the same machine is a
worker running from a home of its own with its own agent directory — the worker touchpoint above, for
when workers exist ([ADR 0003](0003-agents-are-persistent-employees.md)); the predecessor ran its
agents that way.
- **Not decided here:** an automated switch on exhaustion; whether a refresh token is single-use, to be
measured in the lab.
## How it is checked
| Rule | Checked by |
|---|---|
| Only the seat's holder calls the vendor's token endpoint | a catalogue test: no module but the manager names it; the manager's refresh runs under a lease per licence, tested with two concurrent runs |
| A token crosses the bus only sealed, only on request/reply | a bus test: every message the manager publishes as an event carries no token; the hand-over is a request whose payload opens only with the receiving module's key |
| The agent module's private key never leaves the node | the per-key test of ADR 0113, extended to this module's key |
| The host writes nothing under a home and names no vendor | a catalogue test on the agent module's definition: no file resource under a home, no vendor word in anything the host applies |
| A grant is attributed only to a matching identity | a manager test: a grant whose account identity differs from the bound licence's is refused and a notification emitted |
| An unservable binding refuses rather than lends | a manager test: a worker bound to a dead licence is answered with a refusal, never another licence's token |
| A switch through the console changes the token on the node and nothing in the answer is a token | a live check on one workstation |

# 36 — The operator's agent on a machine: the `claude-code` module
**The agent a person runs at a terminal, put on the machine by the mesh, instructed by the mesh, pointed
at the console, and holding the licence the manager hands it.** It is a member of the family
[to-be 29 §2](29-a-node-has-operator-accounts.md) names, the modules that touch a person's machine, and
its counterpart is [39 — The Anthropic licence manager](39-the-anthropic-licence-manager.md).
What it replaces: the predecessor's module of the same name and a sibling, which placed six files under
the operator's home. The predecessor is retired; the six files are still on both workstations telling
every session to use tools that no longer exist.
**Three rules shape everything below.** The host is module-agnostic: it installs the package and gives
the module a state directory, and knows no vendor, no agent, no path under a home. The controller has no
part beyond resolving what it resolves for every module. And the module handles its own files: the
mesh's part of the agent's configuration is written by the module's own code, from what the mesh
delivered it and what the manager handed it.
## 1. Where the mesh's configuration lives: the agent's managed directory, not the home
The agent reads a machine-wide, administrator-owned configuration directory under `/etc`, documented
by the vendor: a managed settings file that outranks every user and project setting; a key in it that
adds HTTP tool servers *beside* a person's own without blocking them; and a managed instruction file every
session reads before the user's and the project's. The agent has **no** machine-wide directory for
rules, skills, slash commands or hooks; those exist only under a home or a project.
So the mesh's part of the agent's configuration lives there, **owned whole by the module**, and the home
is left alone. What the predecessor shipped as two rule files and two skills folds into the managed
instruction file and the manager's tools:
| the predecessor placed | becomes |
|---|---|
| `~/.claude/CLAUDE.md` | the managed instruction file: how a session on this mesh works (§3) |
| `~/.claude/rules/00-hal-mesh.md`, `~/.claude/rules/conventions.md` | sections of the same file: this node's identity, the repositories' conventions |
| `~/.claude/settings.json`, merged | the managed settings file: the mesh's keys only, outranking nothing a person did not also set |
| `~/.claude/skills/hal-switch-license/SKILL.md` | the manager seat's `switch` verb, listed by the console, and a sentence in the instruction file saying to use it |
| `~/.claude/skills/cleanup/SKILL.md` | nothing; it named the predecessor's forge |
| the console's entry in the agent's user-scope state | the managed settings' tool-server key, from the console's provision (§4) |
**The home.** Under [ADR 0182](../../02-DECISIONS/0182-inside-a-home-the-mesh-owns-what-it-places-and-holds-the-rest-as-found.md)
every path under `~/.claude` is *found*, with one exception: the agent's credentials file, which the
module's own code writes for a subscription licence (§5). The person's memory, history, projects, local
settings, their own rules, skills and tool servers are never read or written by the mesh. **The six
predecessor files are the operator's to remove, once, on each workstation**; the module's documentation
lists them, and until they go the agent reads stale instructions beside the mesh's.
## 2. What the module declares and what its code writes
**Declared, applied by the host:** the agent's package (§7); the module's state directory; a facts file
in that directory carrying the node's name, the operator account, the console's endpoint, the module's
settings; the bus, the console's provision, and that it uses the `anthropic-licence-manager` seat.
Nothing under the home, nothing under `/etc`.
**Written by the module's code**, from the facts file and the manager's hand-over, whenever either
changes:
| path | content |
|---|---|
| the managed settings file | the mesh's keys: the tool servers (the console, plus any the operator declared as settings), the attribution trailers, and — for an API-key binding only — the key-helper that serves the key |
| the managed instruction file | §3 |
| the agent's credentials file under the operator's home | for a subscription binding only: the access token the manager handed over, as the operator, readable by the operator alone, atomic, no refresh token |
| the module's keypair in its state | made once, the private half never leaves (§5) |
Writing under `/etc` and as the operator under the home are two escalations the module's code performs
for itself; the mesh does not run the module as root for everyone, and the caller does not know
([ADR 0175](../../02-DECISIONS/0175-one-tool-runtime-per-node-serves-every-modules-tools-on-the-host-side.md)).
**Which settings keys are the mesh's.** A key is the mesh's when it encodes a rule of the mesh: the tool
servers that reach the mesh, the attribution convention of its repositories, the key-helper a binding
requires. The model, the spinner, the drafts and every other preference are the person's, and the
predecessor's experience with the model key is the evidence: a mesh that sets a preference reverts a
person's choice on every push.
## 3. What the instruction file says
Prose, not a paste; the file is the module's.
**How a session on this mesh works.** The console is the only path to the mesh, and its tools are the
vocabulary: the record is asked through the records module, symptom first — the literal error text before
a hypothesis ([ADR 0153](../../02-DECISIONS/0153-the-record-is-read-by-a-module-and-the-console-lists-it.md));
the mesh is asked and changed through the controller seat's verbs; the forge through the forge module's
tools; a licence through the `anthropic-licence-manager` seat's verbs, never by editing a file. The hard
rules in new words: a file the mesh manages is changed through the verb that owns it or through the
catalogue, never on disk; a store's database is never written by hand; main is never pushed; the mesh
creates no symlinks and nobody else does; a package is declared, not installed by hand. The glossary's
words, none of the predecessor's.
**Who this node is.** The node's name, from the facts file; the node's role, from the module's settings
on the node's layer; and that the other nodes are asked of the controller's `nodes` verb rather than
listed here, because a table is a copy that drifts.
**The repositories' conventions.** Concise commit messages in the imperative, about why; a branch, a
pull request and a human approval for every merge; test before pushing, because nodes update unattended;
the playbooks in the record.
## 4. The console
The module tells the agent where the console is, and the port is the console's to say. **The console
provides a node-scoped provision** — its MCP endpoint on loopback — serving the port the machine gave
it, and the module requires it. A requirement names what the consumer is coupled to
([ADR 0027](../../02-DECISIONS/0027-a-provision-names-what-the-consumer-is-coupled-to.md)); co-location
resolves it; a machine without the console refuses the module by name. [To-be 34](34-the-console.md) is
amended in the same change; issue 192 (open) found the gap.
**Other tool servers** a person wants on every machine, or on one, are a declared setting of this module
— mesh layer or node layer — rendered into the same managed key. A module tool, `mcp_configure`,
validates a server and sets the setting through the controller's settings verb, so the list stays
declared state. The agent's own HTTP-only constraint for managed servers applies; a person's local
command-based servers stay their own, in their own file.
**The entry's name is `mesh`.** The hand-made entry both workstations carry today is named after this
installation, which a definition may not be ([ADR 0155](../../02-DECISIONS/0155-a-definition-names-no-installation-and-how-that-is-checked.md));
it is the person's to remove, and until then the agent sees the mesh's tools twice.
## 5. The licence: the consumer side
[ADR 0183](../../02-DECISIONS/0183-the-anthropic-licence-manager-is-a-module-and-hands-tokens-to-the-agent-over-the-bus.md)
decides it; to-be 39 is the manager's half. This module:
- **makes a keypair** in its state the first time it runs and registers the public half with the seat;
- **serves `apply`**: the manager's hand-over, a token sealed to the module's key, with the licence's
name and kind. A rotation of the same licence is applied only if newer within one lineage; a switch is
applied regardless, because across licences the expiries are unrelated. The answer says applied or
refused and why, and never echoes a token;
- **pulls** at start and when its token nears expiry, by the seat's `current` verb, and keeps the last
token when the manager does not answer, saying so;
- **writes** for a subscription licence the credentials file as the operator, access-token-only; for the
API-key licence sets the key-helper in the managed settings to a small program that prints the key
from the module's state, so no file under the home is touched;
- **offers a login to the manager**: when the credentials file changes by a person's login, it reads the
account's identity from the agent's state file and offers the grant to the seat, sealed to the manager's
key, for adoption; the manager decides;
- **serves `licence_status`**: which licence and kind this node holds, when the token expires, whether
the file matches what was handed over — by fingerprint, never by value.
Switching is the seat's `switch` verb, asked through the console; this module only applies what it is
handed.
## 6. Scope, settings and the order of assignment
**Every node with an operator account** ([ADR 0181](../../02-DECISIONS/0181-the-operator-account-is-a-node-fact-and-a-home-is-a-placement-root.md)).
None has one today; the operator states them first. **Per node:** the role. **Per mesh or per node:**
extra tool servers. **Prerequisite:** the manager holds its seat and has adopted the licences.
**Order:** the manager assigned and a refresh observed; the console's provision in the catalogue; this
module on one workstation; the six predecessor files and the hand-made console entry removed there; a
new session read to confirm it sees the mesh's instruction file, the console's tools under `mesh`, and
its licence; then the rest.
## 7. The package
The module declares the agent's package. The distribution every node runs does not carry it in its
repositories: the two workstations have it from a build the predecessor's helper made from the community
repository, and nothing updates it since. On those two the declaration is satisfied. **On a fresh machine
the host's package manager refuses it, in its own words, and the module is not applied there.** The
answer is a package repository for this ecosystem as a seat
([ADR 0109](../../02-DECISIONS/0109-a-package-registry-seat-is-one-per-ecosystem.md)), fed by the builder
and trusted by every node's package manager; not built, and not this module's to build. The vendor's own
installer is rejected: it puts a self-updating binary under the person's home, invisible to the mesh.
## How it is checked

- **A worker's own licence on a machine.** Every interactive session shares the node's one agent
directory and its licence, however many run. A worker runs from a home of its own with an agent
directory in it, bound to its own licence through the manager (to-be 39 §5); that is for when workers
exist, and nothing here changes for it.
- **The package repository seat** (§7).
- **How the module's tools are run** is decided: the node's tool runtime, host-side
([ADR 0175](../../02-DECISIONS/0175-one-tool-runtime-per-node-serves-every-modules-tools-on-the-host-side.md)).
The managed files and the credential write are tools of this module that runtime serves. Until the
runtime exists on every node, the module's code runs as a supervised process of its own
([ADR 0150](../../02-DECISIONS/0150-a-modules-own-code-runs-as-supervised-processes-under-one-account.md)),
which changes nothing in what it writes.

# 39 — The Anthropic licence manager
**One module knows every Anthropic licence the mesh has, keeps each alive, decides which consumer gets
which, and hands every node's agent its token over the bus.**
[ADR 0183](../../02-DECISIONS/0183-the-anthropic-licence-manager-is-a-module-and-hands-tokens-to-the-agent-over-the-bus.md)
decides it; this is the shape. It is the successor of the predecessor's manager module, built from what
that module learned the hard way, and the counterpart of [36 — The operator's agent on a machine](36-the-operators-agent-on-a-machine.md),
which is the consumer on every node.
## 1. What it is
A module, `claude-licence-manager`, holding the mesh-scoped seat **`anthropic-licence-manager`**. One
holder, on the node the operator assigns it to — the control node is the natural one, and nothing in the
definition says so. It requires a database for its own store and the bus; it claims the seat; it serves
the seat's verbs. It has no port, no route, no file under anyone's home.
Its store holds four things:
| table | holds |
|---|---|
| **licences** | name, kind (`subscription` or `api-key`), the account's identity (id, address, organisation) once adopted, the grant encrypted at rest, when the access token expires, when the refresh token expires, consecutive failures, the refresh lease, when a person was last notified |
| **bindings** | one row per consumer: kind (`node-agent`, `node-session`, `worker`), its key (the node, or the node and the worker), the licence, or *inherit* |
| **usage** | the vendor's readings per licence per period, raw beside normalised ([ADR 0054](../../02-DECISIONS/0054-model-usage-is-recorded-at-two-grains.md)) |
| **audit** | every switch, adoption, refusal and drift, with who asked |
**The grants are encrypted with a key the vault made for the manager** — its one `secret` requirement.
The vault keeps that key; the manager keeps the grants. That is ADR 0050's carve-out, one module, one
node, the long-lived grants only.
## 2. The licences it manages today
Two subscription accounts and one API key. They differ in kind and the manager treats them so:
| kind | what the grant is | refresh | what a node is handed | how the agent uses it |
|---|---|---|---|---|
| `subscription` | an OAuth grant: an access token that lives hours and a refresh token that lives weeks | the manager rotates it, alone | the access token only | written into the agent's credentials file by the agent module, as the operator |
| `api-key` | a key the operator obtained from the vendor | none; a new key is a new adoption | the key | served to the agent through its key-helper setting; nothing is written under the home |
## 3. Keeping a grant alive
Carried from the predecessor, where each rule was earned by an incident:
- **One rotation source.** Only this module calls the vendor's token endpoint. An OAuth refresh is
presumed to rotate the refresh token, so a second refresher presenting the old one would kill the
grant; whether that presumption holds is to be measured in the lab, and the design is safe either way.
- **A lease per licence**, taken in the store before the row is read. A duplicate run sees the token its
predecessor just wrote, finds hours of life on it, and does nothing.
- **An expiry floor and a cadence.** Within an hour of expiry a refresh must happen; otherwise a grant is
rotated once it is older than a declared setting, so a node that misses one rotation still holds hours
of life and a broken refresh surfaces in minutes rather than the next morning.
- **Failure is counted and escalated once.** Consecutive failures are recorded; past a threshold a
notification is emitted, and at most once a day while it stays broken — the predecessor sent one alarm
411 times in 35 hours and the incident went unnoticed inside its own alarm.
- **A refresh token's own expiry is warned about three days ahead**, because the only remedy is a person
logging in again.
- **The vendor's reason is logged**, never only the status code: a malformed request and a revoked grant
both answer 400, and the predecessor built three concurrency fixes for a bug that was a wrong client id.
## 4. Handing a token to a node
Every node that runs the agent module registers that module's public key with the seat when it first
runs. From then on:
- **On rotation**, the manager calls `claude-code.apply@<node>` on every node bound to the rotated
licence, with the new token sealed to that node's module key. The module answers *applied*, or
*refused* and why, and the manager records it.
- **On a switch**, the same call with the other licence's token, and the binding is the authority: the
module applies a bind without comparing expiries, because across two licences the numbers are
unrelated.
- **On a pull** — the module starting, or finding its token near expiry — the module calls the seat's
`current` verb for its binding and is answered sealed the same way.
- **Never as an event.** What the manager emits names the licence and the outcome and carries no token.
A node whose module has not registered a key cannot be handed a token, and the manager says so by name
rather than falling silent. A node whose module refuses — a wrong identity, a stale grant within one
lineage — is recorded as drift and reported.
## 5. Who gets which licence
Three consumer kinds, the predecessor's touchpoints with their fallbacks:
| consumer | bound by | falls back to | if the bound licence cannot be served |
|---|---|---|---|
| **the node's interactive agent** | the node | nothing: an unbound node has no licence and the agent says so | keeps the last token, which expires within hours; a notification is emitted |
| **the mesh's session on a node** | the node, for that session | the node's agent licence | refused |
| **a worker** | the worker | the node's session licence, then the node's | refused: a worker never borrows a person's account |
**One agent directory per machine, shared by every interactive session**, so a node's binding is the
licence of all its sessions at once. A worker is a consumer of its own because it runs from a home of its
own, with its own agent directory and credentials file, which the agent module on that node writes for
it as it writes the operator's — the predecessor ran its agents exactly so.
**Binding is a person's act through the seat's verbs**, listed by the console: `bind`, `switch`,
`release`. **Exhaustion is observed, not acted on**: usage is read every few minutes, a crossing of a
declared threshold in the five-hour window is notified once per crossing, and moving a consumer is the
operator's call. Switching remains a reaction, not a declaration
([ADR 0024](../../02-DECISIONS/0024-model-access-is-a-provision.md)), and an automated policy — move to the
least-used licence, stay off a dying one — is designed later if wanted, on the readings this module
already keeps.
## 6. Adopting a grant
A licence enters the mesh one of two ways, and the token never passes through a prompt, a terminal or an
argument:
- **From a node's login.** A person logs in on a node, as they always have. The agent module there reads
the account's identity from the agent's own state file, and offers the full grant to the seat sealed
to the manager's key. The manager adopts it into the licence the node is bound to **only if the
identity matches** that licence's recorded account; a licence not yet identified is identified by its
first adoption; a mismatch is refused and notified, because the predecessor once filed one account's
grant into another's row this way.
- **An API key** is delivered to the manager by the operator through the seat's `adopt` verb from a file
on the manager's node, never as an argument.
## 7. What it emits and serves
**Events**, no secret in any: `licence.rotated`, `licence.switched`, `licence.adopted`,
`licence.failing`, `licence.refused`, `usage.read` — the audit logger records them all.
**The seat's verbs**, the contract every future holder must serve: `licences` (each with kind,
identity, expiry, failures, who is bound), `bindings`, `bind`, `switch`, `release`, `refresh` (now, one
or all), `usage` (current and history), `adopt`, `register` (a node's module key), `current` (a
consumer's token, sealed, asked by the consumer's module).
## 8. Settings
The refresh cadence; the usage threshold; the notification cooldown. Each declared with a default, so
one definition serves and one mesh may differ.
## How it is checked
| Check | Defends |
|---|---|
| two refresh runs started together rotate one grant once; the second does nothing and says so | ADR 0183, one rotation source |
| every event the manager emits is free of any token; the hand-over opens only with the receiving module's key | ADR 0183, to-be 32 §10 |
| a worker bound to a dead licence is refused, never answered with another licence's token | ADR 0183, the fallbacks |
| a grant offered with a mismatching identity is refused and one notification emitted | ADR 0183, attribution |
| a failing licence notifies once, and once a day after, not once per tick | §3 |
| the console lists the seat's verbs and `switch` changes a workstation's token end to end | ADR 0132, the exit of the build |
## What this does not settle
- An automated switch on exhaustion (§5).
- Whether an OAuth refresh token is single-use; the lab measures it, and §3 holds either way.
- How the mesh's own session and a worker read their token on a node once those exist
([to-be 15](15-the-agent-session.md), [ADR 0003](../../02-DECISIONS/0003-agents-are-persistent-employees.md)):
the agent module on that node is their local source, and the reading is theirs to design.

# 40. Building the operator's agent and its licence manager
**The work of [design 36](36-the-operators-agent-on-a-machine.md) and [design 39](39-the-anthropic-licence-manager.md),
broken into packages that each end at something a person can see run, in the order their
dependencies allow.** The two designs are the authority on *what* is built; this document holds the
packages, their order, their sizes and their proofs, and is wrong the moment it disagrees with them.
It is the shape [design 38](38-building-the-operators-machine.md) gave the operator's machine, applied
to the two modules that make its agent work.
## How this is built, and where it is run
**On the live mesh, by the operator's decision** ([ADR 0149](../../02-DECISIONS/0149-the-live-mesh-is-the-test-bed.md),
and design 38's words on the same day). Every package is written with unit tests, committed on one
branch per repository ([playbook 07](../../00-META/process/07-feature-branches.md)), and proven on the
machines: the control node first for the manager, one workstation first for the agent, then the rest.
The cost accepted: a broken agent module leaves a workstation's agent without the mesh's instructions
or with a stale token until the next push; the person's own files under the home are never in reach of
the failure, by [ADR 0182](../../02-DECISIONS/0182-inside-a-home-the-mesh-owns-what-it-places-and-holds-the-rest-as-found.md).
Each package names what proves it. A package that cannot name its proof is divided until it can.
## What exists already, measured
Counted 2026-10-02 in the repositories and on the machines. Nothing here is new ground; every package
reshapes something standing.
| Piece | Today | Becomes |
|---|---|---|
| the vendor's refresh, the sealed box, the grant file | `anthropic-manager` in the catalogue: a token-endpoint client, a sealed-box primitive, adoption of a grant sealed to a node's key; assigned to nothing | the manager's refresh and adoption, with the lease, the floor and the cadence the predecessor's manager had |
| the credentials write, the refresh-token strip, the identity read | `anthropic-consumer` in the catalogue: tested; assigned to nothing | the agent module's write, unchanged in shape |
| the predecessor's manager and consumer | two modules in the retired system: the lease per licence, the expiry floor, the lineage comparison, the identity guard, three touchpoints with fallbacks, cooldowns on alarms | ported as logic with its tests; nothing of its registry or its bus |
| the host's `process` and `archive` shapes | fetch a bundle by digest and run it supervised; fetch and unpack an artifact | **unchanged** — the manager's daemon is one process; both modules' tools are bundles |
| the manifest's `uses`, `claims`, `invokes seat:<seat>.<verb>`, node-scoped `provides` with `serves: {port}` | all four exist and are used by other modules | **unchanged** — the agent uses the seat and invokes its verbs; the console provides its endpoint |
| the console | a container per node, MCP on loopback, no provision | gains one provision; becomes the node-tools runtime's serving mode under design 38's WP3 |
| the agent's package | present on both workstations from a build the predecessor's helper made; the distribution's repositories do not carry it | declared; satisfied where present, refused where not, until a package repository seat exists |
| the operator account | a column on every node record, **empty on all four** | stated by the operator, before anything home-scoped lands |
**One dependency decides the order.** Both modules serve tools and the agent module's tools write
under `/etc` and, as the operator, under the home. Under [ADR 0175](../../02-DECISIONS/0175-one-tool-runtime-per-node-serves-every-modules-tools-on-the-host-side.md)
tools run in the node's tool runtime, host-side, which design 38 builds in its WP1–WP3. Writing a
per-module tool container for these two modules would be building the pattern that record retires, so
**the live proofs of WP3 to WP5 below wait for design 38's WP3.** Everything before a live proof —
manifests, code, tests — does not, and is written now.
## The order the work allows
```
WP0 the operator states the facts (the live mesh) ── accounts, roles, licences to adopt
WP1 the console provides its endpoint (mesh-catalog) ── small, independent
WP2 the licence manager, built and tested (mesh-catalog) ──┐ independent of each other;
WP3 the agent module, built and tested (mesh-catalog) ──┘ both wait on design 38 WP3 to run
│
WP4 the manager live on the control node (the live mesh) ── three licences adopted, a refresh seen
WP5 the agent live on one workstation (the live mesh) ── the hand-over, the switch, the instructions
WP6 the rest of the nodes, and the predecessor's remains ── adoption from a login, the retirements
```
WP1, WP2 and WP3 touch different directories of one repository and meet only at the seat's name and
the provision's name; they are built in parallel. WP4 is the first time anything on a machine changes.
WP5 is the proof of the whole.
## WP0 — The operator states the facts
*The live mesh. An hour, and it is the operator's.*
The account on each node record, through the controller's node command — none is stated today, and
[ADR 0181](../../02-DECISIONS/0181-the-operator-account-is-a-node-fact-and-a-home-is-a-placement-root.md)
refuses a home-scoped module without one. The role of each node, as the agent module's setting on the
node layer, once the module exists. Which three licences exist and what each is called.
**Proof.** The controller's node command lists an account for every node.
## WP1 — The console provides its endpoint
*mesh-catalog. Half a day.*
**What changes.** The console's manifest gains a node-scoped provision — working name
`console-endpoint`, fixed when the manifest is written — serving the port the machine gave it, as the
local model server already does for its API. Co-location resolves it
([ADR 0027](../../02-DECISIONS/0027-a-provision-names-what-the-consumer-is-coupled-to.md),
[to-be 34](34-the-console.md) as amended). When design 38's WP3 moves the console into the node-tools
module, the provision moves with it; it is a line in a manifest either way.
**Proof.** The controller's plan for a workstation shows a consumer of the provision bound to the
console's port; the same consumer on a machine without the console is refused naming the provision;
the catalogue's tests pass.
## WP2 — The licence manager, built and tested
*mesh-catalog. Two to three days; the largest package.*
**What is written**, as design 39 says:
1. **The manifest.** Claims the mesh-scoped seat `anthropic-licence-manager` with its verbs; requires a
database, a `secret` for the key its grants are encrypted with, and the bus; a `bundle` of tools; a
`process` for the daemon that refreshes, collects usage and notifies, on a schedule; declared
settings for the cadence, the usage threshold and the cooldown, each with a default; `invokes` the
agent module's `apply`.
2. **The store.** Migrations for licences, bindings, usage and audit, with the lease and the
notification slot as columns, numbered and idempotent.
3. **The refresh.** The token-endpoint client and the sealed box from `anthropic-manager`; the plan
(floor, cadence, forced, cannot) and the lease from the predecessor, as pure functions with their
tests; the vendor's reason logged on failure; counted failures, one notification per cooldown.
4. **Adoption.** From a file on the manager's node for the API key; from a sealed grant a node offers;
the identity guard that refuses a mismatch and notifies.
5. **Usage.** The vendor's reading per licence on a schedule, stored raw and normalised
([ADR 0054](../../02-DECISIONS/0054-model-usage-is-recorded-at-two-grains.md)), one notification
per threshold crossing.
6. **The verbs**: `licences`, `bindings`, `bind`, `switch`, `release`, `refresh`, `usage`, `adopt`,
`register`, `current` — the last answering a consumer's token sealed to the key that consumer
registered.
7. **The hand-over**: on rotation or switch, one call to `claude-code.apply@<node>` per bound node,
the token sealed to that node's key, the answer recorded.
**Proof, before anything runs live.** Unit tests: two refresh runs started together rotate one grant
once; a grant with a mismatching identity is refused; a worker bound to a dead licence is refused and
never lent another; every event the daemon emits is free of a token; the hand-over payload opens only
with the registered key. The catalogue's checks: no installation named, no secret in a declared file.
## WP3 — The agent module, built and tested
*mesh-catalog. Two days.*
**What is written**, as design 36 says:
1. **The manifest.** The agent's package; the state directory; the facts file carrying the node's
name, the operator account and its home, the console's bound port, the role and the extra tool
servers from settings; requires the console's endpoint and the bus; `uses` the seat and `invokes`
its `register`, `current` and `adopt`; a `bundle` of tools. **No file resource under a home or
under `/etc`.**
2. **The renderer.** From the facts file and the current binding, the managed settings file (the tool
servers under the entry `mesh`, the attribution trailers, and the key-helper for an API-key binding)
and the managed instruction file (§3 of design 36), written under the agent's managed directory
with the escalation the tool performs for itself; idempotent; re-run when the facts file changes.
3. **The keypair**, made once in the state directory, the public half registered with the seat at
start and at every start.
4. **The consumer side**: `apply` (a rotation applied only if newer within one lineage, a switch applied
regardless, the answer naming the outcome and never a token); the pull at start and near expiry;
the credentials write as the operator, access-token-only, from `anthropic-consumer` with its tests;
the key-helper program for the API key; the offer of a login to the seat, sealed, after reading the
account's identity.
5. **The tools**: `apply`, `licence_status`, `mcp_configure` (validates a server, sets the module's
setting through the controller's settings verb), `render` (re-render now, for a person).
6. **The documentation**: the six predecessor files and the hand-made console entry a person removes
on a workstation that carried the predecessor.
**Proof, before anything runs live.** Unit tests: the renderer writes only the mesh's keys and leaves
every other key of a seeded settings file; the credentials write strips a refresh token and is atomic;
the lineage comparison from the predecessor, with its cases; a login offer carries the identity it read.
The catalogue's checks pass.
## WP4 — The manager live on the control node
*The live mesh. Half a day, after design 38's WP3.*
**Order.** Assign the manager on the control node; push. Adopt the API key from a file there. Adopt
the two subscription grants: a login in a throwaway home on the control node, offered to the seat the
way a node's agent module will. Bind each node's agent to a licence.
**Proof.** Through the console: `anthropic-licence-manager.licences` lists three licences with
identity and expiry; within the cadence, the audit shows a rotation and `licences` shows a later
expiry; a forced `refresh` on one licence is logged with the vendor's answer; the two retired catalogue
modules are still assigned to nothing.
## WP5 — The agent live on one workstation
*The live mesh. Half a day. The proof of the whole.*
**Order.** Set the workstation's role in the module's settings. Record the checksums of everything
under the person's agent directory. Assign the module; push. Remove the six predecessor files and the
hand-made console entry. Start a new session.
**Proof.** The managed directory holds the settings and instruction files, owned by root. Everything
under the person's agent directory is byte-identical to before except the credentials file, which is
owned by the operator, readable by nobody else, and names no refresh token. The new session lists the
mesh's tools under `mesh` once, answers *which node am I* from the instruction file, and makes a model
request. `anthropic-licence-manager.switch` to the second subscription licence changes the token on
the workstation within a minute, and neither the verb's answer nor either module's log holds a token.
Switched to the API-key licence, the credentials file is left as it was and the agent authenticates
through the key-helper. Switched back.
## WP6 — The rest of the nodes, and the predecessor's remains
*The live mesh and mesh-catalog. One day.*
**Order.** Assign the module on the second workstation and on the servers whose account is stated;
remove the predecessor's files on the second workstation. Log in on a workstation under a licence's
account and watch the offer be adopted — and under the wrong account, and watch it refused and
notified. Retire `anthropic-manager` and `anthropic-consumer` from the catalogue. Set designs 36 and
39 to `implemented` for what runs, with the as-is written
([playbook 02](../../00-META/process/02-graduation.md)).
**Proof.** Every node with an account runs the module and `licence_status` answers on each; the
refused login's notification arrived; the catalogue has no module built on the old placement.
## What is deliberately not here
- **The package repository seat** for a distribution that does not carry the agent's package
(design 36 §7). A fresh node refuses the module in the package manager's words until it exists.
- **An automated switch on exhaustion.** The readings are kept from WP4; the policy is a later record.
- **Workers and the mesh's own sessions as consumers.** The manager's bindings and fallbacks know them
from WP2; the consumers themselves do not exist yet ([to-be 15](15-the-agent-session.md),
[ADR 0003](../../02-DECISIONS/0003-agents-are-persistent-employees.md)).
- **Whether a refresh token is single-use.** WP4 may measure it on a licence deliberately refreshed
twice; the design holds either way.
## How this list is kept true
Each package's proof is run when the package is finished and its line here gains the date and the
commit, as design 38 does. A package whose proof fails is not reworded; the failure is recorded under
it and the package stays open. When WP5 is proven, designs 36 and 39 move to `in-progress` with their
owning repository, and when WP6 is proven to `implemented`, with the as-is written.
