Writing `/etc/claude-code` needs root. The runtime runs as the operator account, and the module uses
|

that account's passwordless `sudo`; on a machine without it, `claude_code_render` says so and nothing
|

is written.

## Code

|

Go, one binary (`cmd/claude-code`) the node's runtime launches. Tested with `go test ./...`; the managed
|
||||
instruction file is held to the TypeScript renderer it replaced (`testdata/rendered-by-typescript.json`),
|
||||
and the sealed box is the licence manager's own format.

Written by the mesh's \`claude-code\` module. Edit the module's settings or the catalogue, never this file:
|
||||
it is rewritten whenever the module renders.
|
||||
|
||||
## Who this node is
|
||||
|
||||
- **Node:** \`${facts.node}\`
|
||||
- **Role:** ${role}
|
||||
- The other nodes, their roles and what runs where: ask the controller (\`mesh-controller.nodes\`,
|
||||
\`mesh-controller.node\`). Nothing here lists them, because a copy drifts.
|
||||
|
||||
## How a session on this mesh works
|
||||
|
||||
The console is the only way to the mesh: the MCP server named \`mesh\`. It offers five tools, and
|
||||
everything else is an address you find and call through them:
|
||||
|
||||
- \`mesh_search\` — words in, matching addresses out. \`mesh_describe\` — one address's arguments.
|
||||
- \`mesh_call\` — call an address. A seat the mesh holds once is \`<seat>.<verb>\` (the mesh's own verbs
|
||||
are \`mesh-controller.<verb>\`: \`status\`, \`plan\`, \`node\`, \`assign\`, \`push\`, \`settings\`);
|
||||
a module on a machine is \`<node>/<module>.<tool>\`.
|
||||
- \`mesh_overview\` and \`mesh_machine\` — the mesh's seats and machines, and what one machine runs.
|
||||
|
||||
- **Symptom first.** For an error, a failing service or anything unexpected, search the record with the
|
||||
literal text before forming a hypothesis: the records module's \`records_search\`, then
|
||||
\`records_read\`.
|
||||
- **Ask the mesh before changing it**, and change it through the controller's verbs or the catalogue.
|
||||
- **A licence** through the \`anthropic-licence-manager\` seat's verbs. Never edit the agent's credentials
|
||||
file by hand, never print or ask for a token.
|
||||
|
||||
## Hard rules
|
||||
|
||||
- A file the mesh manages is changed through the verb or the catalogue that owns it, never on disk. If
|
||||
unsure, \`mesh-controller.plan\` for the node says what the mesh writes there.
|
||||
- Never write to a store's database by hand; schema changes are numbered migrations.
|
||||
- Never push to a main branch: a branch, a pull request, and a human approval for every merge.
|
||||
- The mesh creates no symlinks, and nobody else does either.
|
||||
- A package is declared in a module, never installed by hand.
|
||||
|
||||
## Conventions
|
||||
|
||||
- Commit messages are concise, in the imperative, about why.
|
||||
- Test before pushing: nodes update unattended.
|
||||
- The playbooks in the record say how research, decisions, designs, issues and hand-offs are done.

# claude-licence-manager
|
||||
|
||||
Holds the `anthropic-licence-manager` seat: every Anthropic licence the mesh has, kept alive by one
|
||||
rotation source, and handed to each consumer sealed (novox/hq ADR 0183, ADR 0206, design 39).
|
||||
|
||||
## How a licence comes to exist
|
||||
|
||||
Nothing is configured. Every node running `claude-code` reports what it holds as that module's
|
||||
`holdings` state — the account, fingerprints and expiries, never a token. This module reads every report
|
||||
when it starts and watches them:
|
||||
|
||||
1. A report with a refresh token it does not hold is a **candidate**.
|
||||
2. It asks that node's `claude_code_grant`, giving its public key, and receives the grant sealed to it.
|
||||
3. **It refreshes it.** If the vendor exchanges the token, the grant is this module's — encrypted at rest
|
||||
with the key the vault made for it — and from then on it is the only refresher. If not, the candidate
|
||||
is recorded dead and nothing is adopted.
|
||||
4. Several nodes logged in to one account: newest login first; the rest are never exchanged.
|
||||
5. A node reporting that account and bound to nothing is bound to it.
|
||||
|
||||
Each node is then handed an access token only, so the agent there never refreshes, and a refresh token
|
||||
appearing on a node later can only be a person's login — which wins if it refreshes.
|
||||
|
||||
An API key enters through `adopt`, from a file on this module's node.
|
||||
|
||||
## What each consumer holds
|
||||
|
||||
This module's `bindings` state: one key per consumer (a node's name) with the licence, its kind and a
|
||||
generation that grows with every rotation and switch. `claude-code` watches its own key and, on a newer
|
||||
generation, asks `current` with its public key.
|
||||
|
||||
## The seat's verbs
|
||||
|
||||
`licences`, `bindings`, `bind`, `switch`, `release`, `refresh`, `usage`, `adopt`, `current` — through
|
||||
the console as `anthropic-licence-manager.<verb>`. No answer carries a token.
|
||||
|
||||
## Settings
|
||||
|
||||
`settings.json` in the state directory: `cadence_minutes` (240), `floor_minutes` (60),
|
||||
`failures_to_notify` (3), `cooldown_hours` (24), `refresh_warn_days` (3).
|
||||
|
||||
## Events
|
||||
|
||||
`licence.adopted`, `licence.refused`, `licence.failing`, `usage.read` — none carries a secret.
|
||||
|
||||
## Code and tests
|
||||
|
||||
Go, one binary (`cmd/claude-licence-manager`): the seat's verbs and the daemon in one launched bundle,
|
||||
`prepare` as the run-once preparation step. The sealed box is `claude-code`'s own format, byte for byte —
|
||||
the two modules carry the same `seal.go` — and a test opens one sealed by the TypeScript agent module the
|
||||
Go one replaced, so the format is the one already on the machines.

# docker
|
||||
|
||||
The container runtime as a module (novox/hq to-be 42 phase 1, item 8; research 027/01–02; ADR 0166,
|
||||
ADR 0207). It claims the node seat `node-container-runtime`. That seat carries no verbs yet: its verbs,
|
||||
and the host creating containers through its holder, wait on ADR 0166's acceptance. Until then the
|
||||
tools below are the module's own.
|
||||
|
||||
## What it declares
|
||||
|
||||
| resource | what | the host's rule |
|
||||
|---|---|---|
|
||||
| `package` | `docker` | installed if absent; never uninstalled when the module goes |
|
||||
| `buildx` | `docker-buildx` | the same. Only the build machine has it today; `docker build` needs it for BuildKit everywhere |
|
||||
| `socket` | `docker.socket` running, enabled at boot | given back as found when the module goes (ADR 0118) |
|
||||
| `prune-service`, `prune-timer` | `/etc/systemd/system/docker-prune.{service,timer}`, written whole | removed with the module |
|
||||
| `prune` | `docker-prune.timer` running, enabled at boot; restarted when either file changes | stopped and disabled with the module (the mesh made the unit) |
|
||||
|
||||
The weekly prune takes **dangling images and build cache unused for a week, and nothing else**. It
|
||||
takes no volume, no container and no image a container uses, so it never touches a container the mesh
|
||||
holds. It runs at idle priority, at a random point in the hour after the weekly mark. A run missed
|
||||
while the machine was off happens at the next boot.
|
||||
|
||||
**Capabilities:** `package-manager`, `service-manager`, `privileged`. It does not declare
|
||||
`container-runtime`: under ADR 0165, which is still proposed, that word means a running daemon, and
|
||||
the module that installs the daemon cannot require it.
|
||||
|
||||
## What it does not declare yet, and why
|
||||
|
||||
Three things this module should own are already declared by other modules on every machine. The
|
||||
controller refuses two modules on one node that declare the same `path`, `unit`, `name` or `package`
|
||||
(`checkResources`, mesh-controller `internal/catalogue/resolve.go`). Declaring any of them here would
|
||||
make the module unassignable everywhere. The refusals were checked against the controller's own
|
||||
check:
|
||||
|
||||
```
|
||||
zsh and docker both declare the name "${machine:account}"
|
||||
dnsmasq and docker both declare the path "/etc/docker/daemon.json"
|
||||
dnsmasq and docker both declare the unit "docker.service"
|
||||
```
|
||||
|
||||
### 1. `/etc/docker/daemon.json` and `docker.service` (issue 190)
|
||||
|
||||
Today the file has three writers. Each writes into it (`into: json`, ADR 0102) and reloads the
|
||||
service:
|
||||
|
||||
- **`dnsmasq`** writes `dns` and `live-restore`, through `dnsmasq.runtime-dns` and `dnsmasq.runtime`.
|
||||
- **The private network**, generated by the controller (`internal/overlay/generator.go`), writes
|
||||
`insecure-registries`. The collision check does not see generated resources.
|
||||
- **Nobody** writes log rotation. One machine has `log-driver` and `log-opts` by hand.
|
||||
|
||||
**The change proposed, in one merge:**
|
||||
|
||||
1. `dnsmasq` drops its `runtime-dns` and `runtime` resources.
|
||||
2. `docker` adds the two resources below:
|
||||
|
||||
```json
|
||||
{"id": "daemon", "type": "file", "path": "/etc/docker/daemon.json", "mode": "0644", "into": "json",
|
||||
"content": "{\"dns\": [\"${machine:address}\"], \"live-restore\": true, \"log-driver\": \"json-file\", \"log-opts\": {\"max-size\": \"100m\", \"max-file\": \"5\"}}\n"},
|
||||
{"id": "runtime", "type": "service", "unit": "docker.service", "state": "running", "boot": "enabled", "reload-on": ["daemon"]}
|
||||
```
|
||||
|
||||
The service is **reloaded, never restarted**: a restart stops every container. The daemon reads
|
||||
`live-restore` on a reload. It reads `dns`, `log-driver` and `log-opts` only at its next start, so
|
||||
they apply then (to containers created afterwards, for the log keys). With `live-restore` on, that
|
||||
start keeps every container running.
|
||||
|
||||
**Why one merge, and only after this module is on every machine:**
|
||||
|
||||
- In one apply, the host first gives back the resources that are no longer declared, then applies
|
||||
the new ones (mesh-host `apply.go`).
|
||||
- `dnsmasq` gives back `dns` and `live-restore` to what they held before it, and `docker` sets them
|
||||
again in the same apply. The daemon is reloaded once, after both steps.
|
||||
- A machine pushed the new `dnsmasq` *without* this module would keep its pre-mesh values for both
|
||||
keys. On one machine that is `live-restore: false`, and the next daemon restart there would stop
|
||||
every container.
|
||||
|
||||
**Later:** the controller hands the registry to this module as a value, and the overlay stops
|
||||
generating its two resources (issue 190, steps 2 and 5). Until then the overlay keeps writing its one
|
||||
key beside this module's. The host merges disjoint keys correctly; the mesh-host `into.go` record is
|
||||
per resource.
|
||||
|
||||
### 2. The operator account's membership of the `docker` group
|
||||
|
||||
The right shape is the host's `user` shape. Its `groups` are additive: the host runs
|
||||
`usermod --append` and never takes a group away.
|
||||
|
||||
```json
|
||||
{"id": "group", "type": "user", "name": "${machine:account}", "groups": ["docker"]}
|
||||
```
|
||||
|
||||
`zsh` already declares a `user` resource for the same account (its login shell). The controller
|
||||
compares `name` across modules, so the two collide.
|
||||
|
||||
**The change proposed (mesh-controller, `checkResources`):** judge a `user` resource by the fields it
|
||||
sets, not by its name:
|
||||
|
||||
- `shell` and `home` stay single-owner;
|
||||
- `groups` may be declared by any number of modules, because the host only adds them.
|
||||
|
||||
Then this module declares the resource above, and no module has to carry another's group.
|
||||
|
||||
Today the operator account is in the group on every machine, by hand. Nothing is lost while it waits.
|
||||
|
||||
## The bootstrap's runtime
|
||||
|
||||
On the machine the mesh was first installed on, the foundation bundle declared `package docker`
|
||||
(`container-runtime`) and `docker.service` running and enabled (`container-runtime-running`). ADR 0207
|
||||
§5 exempts them.
|
||||
|
||||
- The host records them under their bare ids, with origin *carried*. A mesh declaration's orphan pass
|
||||
never sees them (mesh-host `store.go`).
|
||||
- So `docker.package` here is a **second record of the same package**. The apply says "already
|
||||
installed", and neither record ever uninstalls it.
|
||||
- This module does not declare `docker.service` today, so nothing overlaps there. The proposed step
|
||||
1 would add a second record of that unit. Its found state is *running*, because genesis started
|
||||
it, so undeclaring this module would leave the daemon running.
|
||||
|
||||
## Tools
|
||||
|
||||
The tools run as the operator account. If the daemon's socket refuses that account, a call is asked
|
||||
again through `sudo -n` (a process keeps the groups it started with). Every call has a 20 s bound.
|
||||
A failure is an error naming how it failed, never an empty answer.
|
||||
|
||||
**Every container on the machine is in scope.** A container the mesh holds carries the host's label
|
||||
`mesh-host.id` (its value names the assignment), and every answer says `mesh_held`.
|
||||
|
||||
| tool | | what |
|
||||
|---|---|---|
|
||||
| `docker_list` | r | every container: image, state, health, restarts, ports, mounts, compose project, `mesh_held`; filter by owner, state or name |
|
||||
| `docker_inspect` | r | one container whole, **environment values left out** (names kept) |
|
||||
| `docker_logs` | r | the last lines of both streams, merged in order, with timestamps (default 200, at most 2000) |
|
||||
| `docker_stats` | r | CPU, memory, I/O and process count per running container, heaviest first |

| `docker_start` / `docker_stop` / `docker_restart` | a | one container. On a mesh-held one, the answer says the host restores its declared state at its next apply |
|
||||
| `docker_top` | r | the processes inside one container |
|
||||
| `docker_images` | r | images, largest first, with the containers using each; `dangling`, `unused` or `used` |
|
||||
| `docker_prune` | a | dangling images and build cache, and stopped containers the mesh does not hold if `containers` is true. **A dry run unless `dry_run` is false. Never a volume** |
|
||||
| `docker_disk_usage` | r | `docker system df -v`: total, active and reclaimable per kind, with the largest of each |
|
||||
| `docker_networks` | r | networks, subnets, and the containers on each |
|
||||
| `docker_volumes` | r | volumes, who mounts each, whether the mesh holds one of them, anonymous or not, and sizes if asked |
|
||||
| `docker_events` | r | the runtime's events over a window ending now (default 60 min, at most 24 h), without exec noise |
|
||||
| `docker_daemon_config` | r | `daemon.json` as on disk, `docker info`'s essentials, and keys the daemon has not taken yet |
|

| `docker_unlabelled` | r | the containers the mesh does not hold: the cleanup list |
|

## Tests
|
||||
|
||||
```
|
||||
go test ./...
|
||||
```
|
||||
|
||||
The tests run against a fake runner and cover:
|
||||
|
||||
- escalation through `sudo -n` on a refused socket, and never as root;
|
||||
- each failure named by its cause;
|
||||
- a name or id never read as an option;
|
||||
- mesh-held marking;
|
||||
- the environment left out of `inspect`;
|
||||
- the restore note on a mesh-held act;
|
||||
- prune being a dry run by default and never reaching a volume, a mesh container or `--volumes`;
|
||||
- the log merge;
|
||||
- size parsing;
|
||||
- what the daemon has not yet taken;
|
||||
- event filtering;
|
||||
- volume ownership;
|
||||
- that the tools served are exactly the manifest's `tools`.

# ssh-client
|
||||
|
||||
The operator account's `~/.ssh` as a module (novox/hq research 027/03, ADR 0182; to-be 42 phase 1,
|
||||
item 9). `sshd` is the machine's side.
|
||||
|
||||
## What it declares, by ADR 0182's classes
|
||||
|
||||
| path | class | how |
|
||||
|---|---|---|
|
||||
| `~/.ssh/` | owned | directory, the account's, mode 0700 |
|
||||
| `~/.ssh/config.d/` | owned | directory, the account's, mode 0700. This is ssh's own drop-in directory: another module that needs a host (a forge, a work bastion) places its own file here |
|
||||
| `~/.ssh/config.d/00-mesh` | owned | a Host block per other machine of the mesh (a roster fact), regenerated whenever a machine joins, leaves or is renamed. It begins with the mesh's header |
|
||||
| `~/.ssh/config` | written into, **at the start** | the mesh's region, `# BEGIN mesh ssh-client.config` … `# END …`. It holds one `Include ~/.ssh/config.d/*`. Every line below the region is the operator's, kept byte for byte |
|
||||
| `~/.ssh/authorized_keys` | found | see *The gap* |
|
||||
| `~/.ssh/known_hosts` | found | see *The gap* |
|
||||
| private keys | found | never read, never written. `ssh_client_keys` and `ssh_client_check` read a file's first line to recognise a key, and ask `ssh-keygen` about it |
|
||||
|
||||
### Why an include, not Host blocks in the region
|
||||
|
||||
ssh takes the first value it finds for each option. Research 027/03 asks that the mesh's hosts come
|
||||
before anything else in `~/.ssh/config`. Before this change, the region was written at the end: a
|
||||
predecessor's hosts above it won, for the same machines.
|
||||
|
||||
A roster fact cannot be placed at the start. The controller gives facts no `at`, and the host leaves
|
||||
an existing region where it is. So the region at the start holds only the include, and the hosts
|
||||
are a whole file in `config.d` that the include reads first. `00-` sorts it before any other drop-in.
|
||||
|
||||
ssh restores the including file's section after an `Include` (OpenSSH `readconf.c`). So an operator
|
||||
line just below the region is global again, as it was at the top of the file. This module's tests
|
||||
parse the declared region and check it, and `ssh -G` was compared before and after on every machine.
|
||||
|
||||
The old region, `ssh-client.fact-ssh-config` at the end of `~/.ssh/config`, is no longer declared, so
|
||||
the host removes it, and only it, at the first push.
|
||||
|
||||
## The gap: authorized keys and known hosts
|
||||
|
||||
Research 027/03 gives the mesh a region in `authorized_keys` (the operator's keys as the mesh records
|
||||
them) and one in `known_hosts` (every machine's host key). **The controller holds neither fact.**
|
||||
|
||||
- A roster template sees each machine's name, mesh name, address and account, and nothing else
|
||||
(mesh-controller `roster.go`).
|
||||
- No machine fact carries an ssh host key.
|
||||
- The only key the controller knows for the operator is a sealing key for secrets, not an ssh key.
|
||||
|
||||
So both files stay *found*, and this module invents nothing.
|
||||
|
||||
**What would close it:**
|
||||
|
||||
1. The host reports its machine's public host keys in its profile, and the roster gains a field for
|
||||
them.
|
||||
2. The operator's public keys become a mesh record: per account, with a comment saying whose and
|
||||
where.
|
||||
|
||||
Each region is then one more `into: block` resource here. Until then, `ssh_client_check` reads the
|
||||
files as they are, and `ssh_client_revoke` / `ssh_client_known_host` act on them by hand.
|
||||
|
||||
## The one-off clean-up (ADR 0182: the operator removes a predecessor's output, once)
|
||||
|
||||
The mesh removes nothing it did not make. After the first push, a machine that had the predecessor's
|
||||
layout still holds:
|
||||
|
||||
1. **The predecessor's `~/.ssh/config.d/mesh`.** Its hosts repeat the mesh's, with the same values,
|
||||
plus one forge host that no module carries yet. Move that host to your own part of
|
||||
`~/.ssh/config`, or to a work module's drop-in, then delete the file.
|
||||
2. **The predecessor's header at the top of `~/.ssh/config`**, now just below the mesh's region: the
|
||||
comment beginning *"Mesh Host blocks are GENERATED"* and its `Include ~/.ssh/config.d/mesh` line.
|
||||
3. **A predecessor's block of mesh hosts marked *managed by sshd***, on the machines that still have
|
||||
one.
|
||||
4. **Backups beside the live files** (`config.bak-*`, `known_hosts.old`, `removed-*`). `ssh_client_check`
|
||||
lists them as debris.
|
||||
|
||||
Until you do, `ssh_client_hosts` and `ssh_client_check` list the repeated hosts as duplicates. The
|
||||
mesh's still win, because they are read first.
|
||||
|
||||
## Tools
|
||||
|
||||
They run as the operator account and never escalate. No answer carries a key: fingerprints only.
|
||||
|
||||
| tool | | what |
|
||||
|---|---|---|
|
||||
| `ssh_client_hosts` | r | every Host and Match section in the order ssh reads it, each with file, line and source (`mesh`, `drop-in`, `operator`); duplicates; what is set outside any section |
|
||||
| `ssh_client_resolve` | r | `ssh -G` for one host: what ssh would use, and which sections matched |
|
||||
| `ssh_client_check` | r | modes of the directory and every file; keys with no passphrase (`ssh-keygen -y -P ""`, output used only to compare with the `.pub`), weak, old, unused, or whose `.pub` is another key's; one key under several names; the mesh's region first with its include; duplicate hosts; `known_hosts` for the mesh's machines, missing or stale (scanned live, 5 s each in parallel, unless `scan` is false); authorized keys without a comment; debris. It says what it did not check |
|
||||
| `ssh_client_keys` | r | every private key, by its public half: type, size, fingerprint, comment, mode, age, passphrase, whether ssh offers it by itself |
|
||||
| `ssh_client_authorized` | r | `authorized_keys` by fingerprint, type, size, comment and options |
|
||||
| `ssh_client_revoke` | a | removes every line with one fingerprint, keeping the file first as `authorized_keys.revoked-<time>`. It refuses the last key (a lockout) and a key in a mesh region (a push would write it back) |
|
||||
| `ssh_client_known_host` | r/a | known entries against what the host offers now: `matches`, `changed`, `not known` or `unreachable`. With `refresh`, it replaces the host's entries through `ssh-keygen -R` (which keeps `known_hosts.old`) with what was scanned. That trusts whatever answers |
|
||||
| `ssh_client_test` | r | one batch-mode connection that runs only `true`: the address reached, the method and key that authenticated, or why not and which keys were offered. A key with a passphrase works only through an agent. The runtime has none in its environment, so the tool looks for the account's agent socket under `/run/user/<uid>` and names the one it used, or says there was none |
|
||||
|
||||
## Tests
|
||||
|
||||
```
|
||||
go test ./...
|
||||
```
|
||||
|
||||
The tests use a temporary home and a fake runner, with public keys made for the tests only. They cover:
|
||||
|
||||
- reading order and source across includes, with an operator line after the include being global
|
||||
again;
|
||||
- the declared region parsed as ssh reads it;
|
||||
- duplicates;
|
||||
- keys: fingerprints computed as `ssh-keygen -l` does, RSA size, passphrase asked and never prompted,
|
||||
a mismatched `.pub`;
|
||||
- `authorized` never printing a key;
|
||||
- `revoke`: the backup, the mode kept, a lockout refused, a mesh region refused;
|
||||
- `known_host` matching, changed and refreshed, and an unreachable host never refreshed;
|
||||
- `test`: success, and failure with the agent named;
|
||||
- `check`'s findings;
|
||||
- that the tools served are the manifest's `tools`.
