naps62-yolo ade0d49096 chore(maestro): retarget installer, e2e harness, and docs at unified maestro binary (NAP-245)
- Installer: one `cargo install maestro` instead of two; ExecStart becomes
  `~/.cargo/bin/maestro daemon`; user unit renamed `maestrod.service` →
  `maestro.service`; configure step is `maestro daemon configure`.
- E2E harness: both `Daemon` and `Registry` subprocess wrappers shell out to
  the unified `maestro` binary with the appropriate subcommand.
- State dir: `~/.local/state/maestrod` → `~/.local/state/maestro`.
- Docs: CLAUDE.md repo layout, design spec repo layout + "Daemon (`maestro daemon`)"
  heading, INSTALL.md (full rewrite of CLI references + new thin-builds section).

# Installing Maestro
The repo is private, so grab `install.sh` while signed in to gitea, then run it:
1. Open <https://git.naps.pt/naps62/maestro/src/branch/main/install.sh>, click
**Raw**, save as `install.sh`. Or from any existing clone:
```sh
git show origin/main:install.sh > install.sh
```
2. Run it:
```sh
chmod +x install.sh && ./install.sh
```
The bootstrap script builds `maestro-installer` into a temp directory, runs the
wizard, and cleans up — only the unified `maestro` binary ends up persisted in
`~/.cargo/bin`.
**Updating is the same command.** Re-running `./install.sh` detects an
existing `[daemon]` section in `~/.config/maestro/config.toml` and an
existing systemd unit, skips the configure prompt, refreshes the unit, and
runs `systemctl --user restart maestro` instead of `start`. No `--update`
flag needed.
Inside the script, `cargo install --git https://git.naps.pt/naps62/maestro …`
uses your already-configured git credentials for this host (HTTPS helper or
SSH agent). If only SSH is set up:
```sh
MAESTRO_REPO_URL=ssh://git@git.naps.pt/naps62/maestro ./install.sh
```
Pass flags through to the wizard after `./install.sh`:
```sh
./install.sh --yes --no-systemd
```
The wizard:
1. Runs `cargo install` for the unified `maestro` crate (pinned to the
committed `Cargo.lock` via `--locked`). The same binary hosts the CLI,
the per-host daemon (`maestro daemon`), and the always-on registry
(`maestro registry`), gated by Cargo features.
2. Optionally runs `maestro daemon configure` to populate `~/.config/maestro/config.toml`
(one shared TOML for the CLI, daemon, registry, and web).
3. On systemd hosts, optionally writes a user unit at
`~/.config/systemd/user/maestro.service`, reloads systemd, and offers to
enable + start it.
The binary lands in `~/.cargo/bin/maestro` — make sure that's on your `$PATH`.
## Thin builds for single-role hosts
The default install pulls in everything. Registry-only and daemon-only hosts
can opt out of unused dependencies:
```sh
# Registry server — no tmux/PTY/jwt-verifier code:
cargo install --git https://git.naps.pt/naps62/maestro \
--no-default-features --features registry --locked maestro
# Daemon-only host — no embedded web assets, no registry HTTP surface:
cargo install --git https://git.naps.pt/naps62/maestro \
--no-default-features --features daemon --locked maestro
```
The wizard always installs the default-feature build.
## Adding the browser UI (optional)
`maestro-web` is a separate binary that serves the SPA bundle and reverse-
proxies API calls to a co-located `maestro daemon`.
**Interactive install (default path).** The wizard now offers it as an
optional step right after the daemon flow:
```text
Optional: install the browser UI (`maestro-web`)?
Install maestro-web? [Y/n]
```
Press `Y` and it `cargo install`s `maestro-web`, drops a
`~/.config/systemd/user/maestro-web.service` unit (ordered after
`maestro.service`), reloads systemd, and offers to enable + start it. Re-runs
of `./install.sh` detect the existing unit and refresh + restart silently.
Pass `--no-web` to skip the prompt entirely (headless hosts), or `--yes`
with `--no-web` for non-interactive daemon-only installs. (Bare `--yes`
without `--no-web` *skips* the web step too — opt in by re-running once
interactively.)
**Frontend build prerequisite.** `maestro-web` embeds the SPA bundle at
compile time, so before running the installer:
```sh
pnpm -C web install --frozen-lockfile
pnpm -C web build
```
Or `just web` from a workspace checkout.
**Defaults.** `bind_addr = 127.0.0.1:8080`, `daemon_url =
http://127.0.0.1:7070`. The `[web]` section of
`~/.config/maestro/config.toml` overrides both — see
`crates/maestro-web/README.md`.
**Trust model.** Anyone who can reach the bind address can use it. Pick
`127.0.0.1` for local-only, a WireGuard/LAN address for one-segment access,
never a public IP without adding auth first.
Headless hosts (servers, dev VMs) skip the prompt with `--no-web`. Hosts
where you want browser access answer yes — both binaries end up in
`~/.cargo/bin`.
## Flags
| Flag | Purpose |
|---|---|
| `--git <url>` | Install from a different git repo (default: this one). |
| `--branch <name>` | Pin a branch with `--git`. |
| `--path <dir>` | Install from a local workspace checkout (`--path` + `-p maestro`). |
| `--no-locked` | Drop `--locked` from `cargo install` (resolves a fresh dep tree). |
| `--exec-start <path>` | Override the systemd unit's `ExecStart` (default `~/.cargo/bin/maestro daemon`). |
| `--no-systemd` | Skip the systemd step even if detected. |
| `--no-configure` | Skip the `maestro daemon configure` step. |
| `--no-web` | Skip the optional `maestro-web` install step. |
| `--web-exec-start <path>` | Override the web unit's `ExecStart` (default `~/.cargo/bin/maestro-web`). |
| `-y`, `--yes` | Non-interactive: install binaries + drop systemd unit + reload + enable, but **don't** auto-run `configure` or auto-start the unit (those need real config). Also skips the web step unless an existing `maestro-web.service` is being refreshed. |
## Where tmux sockets land
`maestro daemon` defaults `TMUX_TMPDIR` to `$XDG_RUNTIME_DIR` (= `/run/user/$UID`)
so a plain `tmux ls` in your shell — which typically uses the same env var
— sees maestro-managed sessions. Override in
`~/.config/maestro/config.toml`:
```toml
[daemon]
tmux_tmpdir = "/tmp"
```
Pick `/tmp` if the daemon must outlive your login session and you can't run
`loginctl enable-linger` (the runtime dir is wiped on logout, taking the
tmux sockets with it). The env var `MAESTRO_DAEMON_TMUX_TMPDIR` takes
precedence over the file.
## Hot-reloading policy
`[daemon.policy].allow_inbound` (the list of peer daemons allowed to broker-
attach into this one) can be changed without restarting the daemon — restarting
would kill every live session. Three ways to apply an edit:
```sh
maestro policy reload # POSTs to the local daemon's /api/policy/reload
maestro policy show # prints the current effective list
kill -HUP <maestro-pid> # equivalent; what `systemctl --user reload` does
```
Only newly-arriving attach attempts see the change — sessions already
attached stay attached. To boot a live attacher out, kill the session.
## What the systemd unit looks like
The wizard writes a *user* unit (`systemctl --user`), since `maestro daemon`
runs per-user and uses tmux sockets under `$XDG_RUNTIME_DIR`. Body:
```ini
[Unit]
Description=Maestro per-host daemon
Documentation=https://git.naps.pt/naps62/maestro
After=network-online.target
[Service]
Type=simple
ExecStart=%h/.cargo/bin/maestro daemon
ExecReload=/bin/kill -HUP $MAINPID
Restart=on-failure
RestartSec=5
[Install]
WantedBy=default.target
```
Check status / logs:
```sh
systemctl --user status maestro
journalctl --user -u maestro -f
```
## Running the wizard without the bootstrap script
If you'd rather skip the script:
```sh
cargo install --git https://git.naps.pt/naps62/maestro maestro-installer
maestro-install
```
This leaves `maestro-installer` permanently in `~/.cargo/bin` — the bootstrap
script avoids that by installing to a scratch dir.
## Fully manual install (no wizard)
```sh
cargo install --git https://git.naps.pt/naps62/maestro --locked maestro
maestro daemon configure
maestro daemon # foreground; or wire your own service manager
```
## Non-Linux hosts
The wizard works on macOS for the `cargo install` + `maestro daemon configure`
parts. The systemd step is automatically skipped (probe of
`/run/systemd/system`). launchd integration is not yet supported — start
`maestro daemon` from your shell or your own service manager.
