# betterbird
|
||||
|
||||
Betterbird, the mail and calendar client of g14 and shanks (a Thunderbird fork, with the operator's
|
||||
Exchange calendar through the Owl add-on), as a module (novox/hq issue 345, ADR 0208). It requires
|
||||
`x11-display`, so it is assigned only where a display server is held on the same machine.
|
||||
|
||||
It exists because a symptom had no tools: on a workstation, a calendar reminder appeared as a
|
||||
transparent window with nothing in it (2026-10-09). Nothing in the mesh could say which window that
|
||||
was, how the compositor treats it, or which preferences Betterbird ran with. The diagnosis is in hq
|
||||
issue 345.
|
||||
|
||||
## Owns
|
||||
|
||||
| what | where |
|
||||
|---|---|
|
||||
| the module's directory | `~/.config/betterbird/` |
|
||||
| the module's `user.js`, filled from the setting `prefs` | `~/.config/betterbird/user.js` |
|
||||
|
||||
Nothing else. It holds no seat and adds no start.
|
||||
|
||||
- **No package.** g14 and shanks both run `betterbird-bin` 153.1.0esr-1, installed explicitly from the
|
||||
AUR: `pacman` counts it as foreign. The node-engine installs packages from the official
|
||||
repositories only, so the module does not declare it, and **installing and upgrading Betterbird stay
|
||||
the operator's** (an AUR helper). `betterbird_status` says the version and that it is from the AUR;
|
||||
`betterbird_check` says when it is missing.
|
||||
- **No start.** Betterbird is started by the operator from the launcher (on the workstation measured,
|
||||
it runs in the login session's scope, started by hand, with no autostart entry and no line in i3's
|
||||
configuration). `betterbird_restart` starts it as the transient user unit `mesh-betterbird`, so its
|
||||
output then goes to the journal.
|
||||
- **The profile is Betterbird's** (ADR 0182): `~/.thunderbird/` holds the mail, the address books,
|
||||
the calendars' caches, the logins and the keys. The module declares none of it.
|
||||
|
||||
## The user.js: how a preference is declared
|
||||
|
||||
Betterbird reads `user.js` in its profile when it starts, and a preference set there wins over the
|
||||
one it saved in `prefs.js`. The profile's directory has a random name per machine
|
||||
(`<random>.default-default`), which a manifest cannot name. So:
|
||||
|
||||
1. the node-engine writes `~/.config/betterbird/user.js` from the module's setting `prefs`, one line of
|
||||
`user_pref("name", value);` statements (default: a comment, no preference);
|
||||
2. the module's tools copy that file whole into the profile: `betterbird_user_js` with `apply`, or
|
||||
`betterbird_restart`, which places it before it starts Betterbird again;
|
||||
3. Betterbird reads it at that start.
|
||||
|
||||
**The profile is found** as the one the running Betterbird holds open; with none running, as the
|
||||
installation's default in `profiles.ini` (`[Install…] Default`), else the profile marked `Default=1`.
|
||||
On the workstation measured these differ: `Profile1` is marked `Default=1`, and the installation's
|
||||
default, the one in use, is the other.
|
||||
|
||||
**A user.js the module did not write is never overwritten.** The module's begins with the line
|
||||
`// Betterbird's user.js (module betterbird`; any other is the operator's, and `apply` refuses with
|
||||
what to do. The tools refuse a declared file that holds anything but comments and `user_pref`
|
||||
statements, or that sets a preference whose name can hold a credential.
|
||||
|
||||
The file is **trusted** (it carries no `"trusted": false`): a preference can weaken how the mail client
|
||||
checks a server, so the setting is changed only at the controller's terminal, never through a verb
|
||||
(novox/hq issue 339).
|
||||
|
||||
## Tools
|
||||
|
||||
They are served by the node's runtime as the operator account (ADR 0175). **No answer carries mail, a
|
||||
calendar entry, an account, an address or a credential.**
|
||||
|
||||
| tool | does |
|
||||
|---|---|
|
||||
| `betterbird_status` (r) | whether it runs (pid, since, scope, children), the package and version and that it is from the AUR, where its output goes, the profile and how it was found, the user.js (declared, placed, in effect), the add-ons the operator installed (ids), and the preferences that decide how its windows and notifications look |
|
||||
| `betterbird_prefs` (r) | named preferences or prefixes (ending in `.` or `*`, at most 200; an empty name, `*` or `.` is refused): value and source (user.js, prefs.js or the default). Withheld without its value: a name that can hold a credential (`password`, `token`, `oauth`, `signon`, …); one that names an account, server, calendar, recent folder or person (`mail.server.`, `mail.identity.`, `mail.last_msg…`, `messenger.account.`, `mail.cloud_files.`, `calendar.registry.`, …); and every `extensions.*` but the theme's id (`extensions.activeThemeID`). In every value answered, the home is `~`, and a mail address, a `user%40domain@host` URI and a host name are masked |
|
||||
| `betterbird_user_js` (r; a with `apply`) | the declared user.js against the profile's; `apply` places it |
|
||||
| `betterbird_log` (r) | the last lines of the journal of `mesh-betterbird` (or of the reminder test), addresses and credentials masked (the value after `password=`, `token:` and the like, and the token after `Bearer`/`Basic`). A Betterbird the module did not start prints elsewhere, and the answer says where |
|
||||
| `betterbird_restart` (a) | ends Betterbird (asked to quit, forced after 8 s), places the user.js where allowed, starts it as `mesh-betterbird`. **Refused while a composer window is open** (X instance `Msgcompose`, whatever its class), because the unsent message would be lost, unless `discard_unsent` is true, which only the operator's yes justifies. It answers within the runtime's 30 s: a start not yet seen after 4 s is said in `note`, and `betterbird_status` shows it |
|
||||
| `betterbird_check` (r) | installed; one running; profile found; the user.js on the machine, valid, placed, in effect; its output read |
|
||||
| `betterbird_reminder_test` (a) | a reminder on demand without the operator's calendar (below) |
|
||||
|
||||
### A reminder on demand
|
||||
|
||||
`betterbird_reminder_test` starts a **second** Betterbird with `--no-remote` in a throw-away profile
|
||||
under `/run/user/<uid>/mesh-betterbird-reminder-test/`, as the user unit
|
||||
`mesh-betterbird-reminder-test` (ended after 10 minutes at most). The profile holds the module's
|
||||
user.js and one calendar: a local `.ics` file with one event, "Mesh reminder test", whose reminder is
|
||||
due `after` seconds from the call (default 40). `carry` copies named preferences of the operator's
|
||||
profile into it (a theme, a colour switch), under the same limits as `betterbird_prefs`. Then:
|
||||
|
||||
- `xorg_windows` with class `Calendar` answers the reminder window: role `AlarmWindow`, type `Dialog`,
|
||||
its depth (32: a visual with alpha, which the compositor blends), its map state;
|
||||
- `xorg_screenshot` with that window shows it as the screen shows it.
|
||||
|
||||
The unit removes its profile when it ends, however it ends (`ExecStopPost`): at its 10 minutes, on
|
||||
`stop`, or when the test window is closed. The test Betterbird is never counted as the operator's: its
|
||||
command line names its own profile, and `status`, `check`, `restart` and the user.js leave it out.
|
||||
|
||||
The running Betterbird, its profile and its calendars are not touched: `--no-remote` keeps the two
|
||||
apart. **`profiles.ini` and `installs.ini` are not rewritten either**, measured on the workstation
|
||||
(2026-10-09): their content and modification time (June 2023) were the same before a `--profile` start,
|
||||
while it ran, and after it ended.
|
||||
|
||||
## The reminder window, as measured (2026-10-09, workstation, i3 and picom with glx)
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| X class / instance | `eu.betterbird.Betterbird` / `Calendar` |
|
||||
| role, type | `AlarmWindow`, `_NET_WM_WINDOW_TYPE_DIALOG` (i3 floats it) |
|
||||
| depth | 32 (ARGB visual), like every Betterbird window there |
|
||||
| size | 600×300, kept in the profile's `xulstore.json` |
|
||||
|
||||
A window of depth 32 that its program has not drawn is transparent under a compositor, not black:
|
||||
that is why the symptom looks the way it does. Why Betterbird did not draw it is hq issue 345's
|
||||
question.
|
||||
|
||||
## What changes when it is assigned
|
||||
|
||||
| | g14 | shanks |
|
||||
|---|---|---|
|
||||
| files | `~/.config/betterbird/` and its `user.js` (no preference) | the same |
|
||||
| the profile | untouched until `betterbird_user_js` with `apply` or `betterbird_restart` | the same; the profile has no user.js today, so `apply` may place one |

Two directories, declared, so the mesh refuses a second module owning either:
|
||||
|
||||
- `/etc/claude-code`, the agent's machine-wide managed directory, root's, `0755`.
|
||||
- `~/.claude` under the home of the account agents run as (the operator's, unless the machine names an agent
|
||||
account of its own), that account's, `0700`. The module owns the directory —
|
||||
- `~/.claude` under the operator account's home, the operator's, `0700`. The module owns the directory —
|
||||
that it exists, who owns it, its mode — and of what is inside only what it writes. Everything else
|
||||
in it (memory, history, projects, local settings, a person's own rules and skills) is the person's
|
||||
and is never read or written (hq ADR 0182). Unassigned, the module leaves the directory: the host
|
||||
removes a directory only when it is empty.
|
||||
|
||||
And, for where the agent runs as an account of its own (hq ADR 0266):
|
||||
|
||||
- **the account agents run as**, a `user` named by the machine fact `agent-account` — the operator's
|
||||
account where the machine names none, which declares nothing new of it. Where it names one, the mesh
|
||||
makes the account (its home, its own group, no password, no group of the mesh's) and asks the node-engine
|
||||
to judge `root: never` on every look: that it is not root, is in no group that grants root, has no sudo
|
||||
rule and can read no secret the mesh placed for another account. A way found is this module's condition,
|
||||
and the controller's self-check says it urgently.
|
||||
- `/usr/local/bin/claude-agent`, root's, `0755`: starts the agent as that account — `claude` itself when run
|
||||
as it, otherwise `sudo -iu <account> claude` through the operator's own sudo, carrying the guard's
|
||||
override only when it is set in the operator's shell.
|
||||
- `/etc/claude-code/agent-account`, root's, `0644`: the name of that account, the machine fact
|
||||
`agent-account`, for the shell to read — the controller fills no machine fact into shell code.
|
||||
- **`claude` in the operator's interactive zsh is `claude-agent`** where the machine names an agent account:
|
||||
zsh code in the login shell's `normal` slot (hq ADR 0204) reads that file and adds
|
||||
`alias claude=claude-agent` only when it names an account other than the shell's own. Where agents run as
|
||||
the operator's account the file names that account, and nothing is added. `claude-agent` still runs the
|

real `claude`: an alias is a word of an interactive zsh, and neither `exec`, `sudo` nor its `sh` sees it.

|

|

## Where the agent runs as an account of its own (hq ADR 0266)
|
||||
|
||||
A machine may name an **agent account** beside the operator's, at the controller's terminal
|
||||
(`mesh-controller node agent-account <node> <account>`); the control node does. Agents there run as that
|
||||
account, which cannot become root without a person, and the operator keeps their own account and its sudo.
|
||||
The runtime hands this module `MESH_AGENT_ACCOUNT` and `MESH_AGENT_HOME` — the operator's where none is
|
||||
named, and read as the operator's from a controller that sets neither — and everything it writes for the
|
||||
agent goes to that account's home:
|
||||
|
||||
- the licence token (`~/.claude/.credentials.json`) and the account it is logged in as (`~/.claude.json`);
|
||||
- an API-key licence, in `~/.claude/mesh/`, since the account cannot enter the module's state. Its key-helper
|
||||
is no script there: the managed settings apply to every account's `claude`, the operator's and root's too,
|
||||
so a script the agent owns would run as them. The managed settings carry the command whole instead, and it
|
||||
reads the key only when run as the agent's account;
|
||||
- the items registered at the home scope, recorded per home (`home-placed-<account>.json`).
|
||||
|
||||
The runtime's account cannot enter that home (0700, the agent's), so a path under it is touched by a
|
||||
**helper running as the agent's account**: this module's binary as the plugin carries it
|
||||
(`/etc/claude-code/marketplace/plugins/nox-mesh/guard/guard home-fs`, root's), started once through
|
||||
`sudo -n -u <account>` and kept, one JSON request and answer per line. The escalation goes down only: the
|
||||
runtime's account may become the agent's, never the other way.
|
||||
|
||||
When a machine moves its agent to such an account, the licence follows at once — a binding counts as
|
||||
applied only while the agent's account holds it — and what this module placed under the operator's home
|
||||
goes: the access-token-only credentials file (one holding a refresh token is a login the person made, and
|
||||
stays, said), the home-scope items unless changed by hand, the key kept in the state.
|
||||
|
||||
**The guard there refuses every tool call of a session that does not run as the agent's account** —
|
||||
shell, file edits, reads and the mesh's tools alike — and no override lifts it: the operator's account may become root, and an
|
||||
agent started in it by habit must do nothing. Its record goes to the machine's journal
|
||||
(`journalctl -t mesh-claude-code-guard`), which the session's account may add to and not change;
|
||||
`claude_code_guard` reads it there, keeping only the lines the journal says the guard's own binary wrote. That
|
||||
is not proof: the account can run the guard's binary itself and add lines in the guard's words. What it
|
||||
cannot do is remove one.
|
||||
|
||||
**An API key is taken only from the agent's own home.** `claude_code_add_api_key` reads a file and removes it,
|
||||
and the runtime runs as the operator: a path anywhere would hand whoever calls it the runtime's credential or
|
||||
the operator's keys. So the file must lie under the home of the account the agent runs as, reached through no
|
||||
symbolic link, is read as that account, must be at most 4 KiB and hold an Anthropic API key (`sk-ant-…`) —
|
||||
otherwise nothing is handed over and nothing removed, and the refusal never repeats what the file holds. The
|
||||
licence manager refuses a key of another shape too.
|
||||
|
||||
## Escalation
|
||||
|
||||
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. The same sudo starts the helper as the agent's account, where there is one.
|
||||
is written.

# desk-channel
|
||||
|
||||
The desk as a channel of the operator's conversation: kind `desktop` of the `channel` and `intake` benches the
|
||||
router (`messenger`) declares (novox/hq ADR 0258, ADR 0259). It shows the router's messages on the notifier of
|
||||
each machine the operator sits at (the `node-notifier` seat), and says which button was chosen there.
|
||||
|
||||
- **It proves nothing about who clicked.** Any process of the operator's account can choose a notification's
|
||||
action (`dunstctl action`), so its claim declares no `verified-sender`: the router offers here only
|
||||
acknowledgements (Silence for a week, Details) and says in the words where an approval can be given.
|
||||
- **An answer is taken only on a machine its message was shown on**, and once; a refused click is said where it
|
||||
was made. A message with buttons stays until it is dismissed.
|
||||
- **What it remembers is never shown again** (issue 384: on 2026-10-10 a notifier that started again was
|
||||
shown nine old popups from the desk's memory, resolved and silenced ones among them). Its memory — which
|
||||
notification each handle has on each machine — serves only to replace or edit a message in place. When the
|
||||
notifier's bundle starts again on a machine (`dunst.started`), its notifications stay on screen and the
|
||||
answers they waited for are lost: the desk keeps their ids and says in its standing when that happened
|
||||
(`answers-lost-at`); the router, which alone knows what is still open and unanswered, says that again under
|
||||
its handle, replacing the notification in place so its buttons work again. Nothing resolved, silenced or
|
||||
cancelled comes back.
|
||||
- A message no machine took is said to the router as failed; the router tries it again.
|
||||
- **One notification per message** (issue 373): an `edit`, and a `send` or `show` under a handle already shown (a
|
||||
reminder, an escalation), replace that message's notification on each machine by its id (the notifier's
|
||||
`replace_id`), so a problem is one notification updated in place. An edit goes only where it was shown; a
|
||||
message said again is shown anew on a machine it was not. A replace that fails on a machine keeps that
|
||||
machine's notification on record, so a later edit still reaches it.
|
||||
|
||||
## What the operator gives
|
||||
|
||||
The machines to show on, as a setting: `settings` for `desk-channel` with
|
||||
`{"desktop-machines": ["<the machine the operator sits at>", …]}`. Until then it says it cannot send, and the
|
||||
router sends warnings to the channel that reaches the operator away.
|
||||
|
||||
## Where it runs
|
||||
|
||||
Held once for the mesh, on the same machine as the router, which is where it is assigned. **It runs as the
|
||||
account `desk-channel`, in a runtime of its own, on a bus account of its own** (`runs-as`), as telegram does:
|
||||
what it shows and the answers it says are out of reach of the operator's account, which agents run as. It asks
|
||||
each machine's notifier through the mesh: nothing new runs on the machines.
|
||||
|
||||
## A link's code (the review of 2026-10-09)
|
||||
|
||||
- **It is shown only where it is seen.** Each machine's notifier says whether it is paused (`dunst.paused`, at
|
||||
least every two minutes). A message the router marks secret is shown only on a named machine heard unpaused in
|
||||
the last five minutes; while there is none, it is said to the router as failed and the desk says it cannot
|
||||
send, so the router starts no link. A code held by a paused notifier would appear later, to whoever is at the
|
||||
screen then.
|
||||
- **It is kept nowhere.** Not in this module's state, and sent `secret` to the notifier, which sends it
|
||||
transient in the category `mesh.secret`: dunst's rules keep it out of its history, and
|
||||
`node-notifier.history`, which every caller of the mesh's verbs may read, leaves it out.
|
||||
- **What remains**: while it is on screen, a program of the operator's account on that X display can read it
|
||||
(X11 isolates no client from another). It is shown for as long as the router's code lives.

## Log rotation (novox/hq issue 452)
|

|
||||
`daemon` writes `"log-driver": "json-file"` and `"log-opts": {"max-size": …, "max-file": …}` from two
|
||||
preferences: `log-max-size` (default `100m`) and `log-max-file` (default `10`), about 1 GB of log per
|
||||
container. The defaults are what the one machine with rotation set by hand already had, so that machine
|
||||
does not change; the others gain rotation. Both settings are terminal-only (`"trusted": true`).
|
||||
|
||||
**A bad value never reaches `daemon.json`.** The controller pastes a setting into a file as text and judges
|
||||
only that it is one line (novox/hq issue 346), and the runtime is the only reader of `daemon.json`: a bad
|
||||
size would be found as a runtime that does not start, and a quote could add any key. So the same two values
|
||||
are written into `log-rotation.conf` first, and the step `log-rotation-check` judges them before `daemon`
|
||||
is applied: a size is a whole number from 1 with `k`, `m` or `g` after it, a count is 1 to 99. Refused, the
|
||||
step fails, the host skips the rest of this module (ADR 0136), `daemon.json` keeps what it had, and the
|
||||
apply's report names the setting.
|
||||
|
||||
**Nothing restarts.** The runtime reads `log-driver` and `log-opts` only when it starts. A change to
|
||||
`daemon` reloads it, as before; the reload takes neither key, and stops no container. The new rotation
|
||||
holds from the runtime's next start (the machine's next boot, for one), and then only for
|
||||
containers created after it: a container keeps the log options it was created with until it is created
|
||||
again. `docker_daemon_config` lists the keys the daemon has not taken yet.
|
||||
- **Nobody** writes log rotation. One machine has `log-driver` and `log-opts` by hand; they are left

as they are until a size is chosen for every machine.

## Answers from a notification
|

|
||||
`send` with `actions` runs `notify-send --wait` with one `--action` per answer, answers the id at once and
|
||||
waits in this bundle for the operator's choice. A tap (left click) on the notification chooses: with
|
||||
one action it runs it, with several it opens rofi's menu of them, and without any it closes the
|
||||
notification (dunst's `do_action, close_current`; a notification with no action but one link opens the
|
||||
link). An Escape in the menu leaves the notification shown. The middle click does the same, and
|
||||
**Super+N** (`dunstctl context`, this module's line in i3's configuration) opens the menu of every
|
||||
notification on screen from the keyboard. The token `default` is refused, because dunst runs an action of
|
||||
that name at a tap without offering the others. The token chosen is said as this module's event
|
||||
`action-chosen`; it becomes the node-notifier seat's event once seats publish events of their own
|
||||
(novox/hq to-be 46 phase 3). Nothing is said for a notification closed, expired or replaced without an answer, and a wait ends after seven

||||
node-notifier seat's event once seats publish events of their own (novox/hq to-be 46 phase 3). Nothing
|
||||
is said for a notification closed, expired or replaced without an answer, and a wait ends after seven
|
||||
days. A notification that offers answers stays until dismissed (`expire_ms` 0). A restart of this bundle
|
||||
ends the waits it held; it says `started` {machine} once it serves, and the operator channel shows the
|
||||
open answers there again (novox/hq ADR 0258). `notify-send` prints the id before it waits, also into a
|
||||
pipe (checked on the laptop on 2026-10-08: the id at once, and "Wait timeout expired" when it expired).

## What is shown once, and whether it would be seen
|
||||
|
||||
- **A secret notification** (`send` with `secret`: a link's code) is sent transient and in the category
|
||||
`mesh.secret`, whatever category was named. The dunstrc's rules keep it, and every transient one, out of
|
||||
dunst's history (`history_ignore`), and `history` leaves out any that got there anyway, counting them as
|
||||
`withheld`: the history is served to every caller of the mesh's verbs, agents among them.
|
||||
- **Whether notifications are paused** is said as this module's event `paused` {paused, machine}: at start,
|
||||
on every change, and every two minutes, read from dunst itself so a pause set by a key counts too. The desk
|
||||
shows a link's code only on a machine it heard is not paused lately.
