usage: rig <command> [args]

commands:
  bootstrap <control-plane-server|workload-server|runner-server|staging-server|
             dev-server|workstation|custom>
            (--users <path> | --no-users)
            [--hostname <name>] [--class <human|server>] [--host <yes|no>]
            [--join <authkey|login>]
      OS plumbing on a pristine Debian box: hardening, unattended-upgrades,
      tailscale join, then this box's operators. --users is REQUIRED on
      every role — it converges the users file as bootstrap's last phase
      (identical to 'rig users apply --file <path>', marker written first)
      so one command leaves a box with its people on it; --no-users is the
      deliberate opt-out and leaves root as the only door. The tenant roles
      below take neither. Roles are presets over the three traits; any flag
      overrides its trait, and custom states all of them. Prompts for a
      single-use TAGGED tailnet pre-auth key (TS_AUTHKEY env overrides the
      prompt); the key's tags are the tailnet tag, verified after join —
      only control-plane-server and workload-server may carry tag:server.
      The '-server' suffix names the FAMILY (a fleet machine, vs the '-box'
      tenant roles); custom and workstation take none. join=login
      (workstation) needs no key: interactive login, node must come up
      untagged. Run as root.
  bootstrap <claude-box|codex-box|grok-box|kimi-box|staging-box> [--user <name>]
      The box TENANT roles: converge a box-minted guest. The '-box' suffix
      names the family (a guest, vs the '-server' machine roles above).
      claude-box|codex-box|grok-box|kimi-box land the agent toolbelt (git, gh, tmux, docker), the agent's CLI on
      the system PATH, and the agent-context file (with the box#80 guard:
      never run box setup-host inside a box). staging-box lands box#69's
      server posture — docker + sshd hardening; its tailnet join stays
      operator-run via 'rig bootstrap workload-server'. Creds-free and non-interactive: box
      auto-runs these at mint. Run as root, inside the box.
  coolify install --version <pin>
      Pinned Coolify install (AUTOUPDATE=false). Control-plane box only.
  coolify backup install [options]
      Nightly age-encrypted dump of the control-plane database, as a
      systemd timer. rig installs the machinery and templates an empty
      0600 bindings file; you fill in the age recipient and S3 details.
      Control-plane box only. Run as root.
  db <dump|restore> ...
      Ad-hoc PostgreSQL dump/restore for a container on this box. `dump`
      writes a gzipped SQL artifact (--no-owner --no-acl, so it restores
      onto a different instance); `restore` loads one back, connecting as
      the container's own superuser, behind a confirm gate. Run as root.
  platform
      What is this machine: hostname, OS, kernel, CPU, memory, disk and
      virtualization, then rig's own provenance (which rig, when, and the
      role marker bootstrap wrote). Computed at run time from /proc, uname,
      /etc/os-release, df and systemd-detect-virt and stored NOWHERE — a
      spec goes stale the moment someone adds RAM, so there is nothing to
      go stale here. Writes nothing, needs no root, makes no network call,
      and therefore also runs on a pristine Debian box rig has never
      bootstrapped, where the provenance block reads 'not bootstrapped'.
  runner install --repo <owner/repo> [options]
      GitHub Actions runner as a systemd service under an unprivileged
      user — outbound-only, no Docker. Prompts for the short-lived
      registration token (RUNNER_TOKEN env overrides). Run as root.
  runner status [--user <name>]
      What this box's runner is registered to: repo, name, labels, unit.
      Reads the box only — no token, no network call. Run as root.
  runner remove [--local] [--user <name>]
      Take the service down and deregister the runner. Prompts for the
      short-lived removal token (RUNNER_REMOVE_TOKEN env overrides).
      Run as root.
  runner repoint --repo <owner/repo> [options]
      Move an installed runner to another repository — deregister, then
      re-register, reusing the binary already on the box. Needs a removal
      token for the old repo and a registration token for the new one.
      Run as root.
  users apply --file <path>
      Converge named operator accounts from a declarative users file, on
      every class: groups by role (admin/rig/box), passwords locked always,
      authorized_keys made exact, visudo-gated sudoers rules. Users dropped
      from the file are locked, never deleted. '-' reads stdin. Run as root.
  users status
      Roles (derived from actual group membership), key counts and lock
      state for the rig-managed users. Reads the box only. Run as root.
  users close-root
      Shut root SSH on a class=human box once an admin key works. Refuses
      on class=server — root there is the control plane's automation door —
      and while no admin holds a key. Run as root.
  manifest [<key>]
      Print /etc/rig/manifest — which rig converged this machine and when
      (bootstrapped_by/_at pin the FIRST convergence forever; converged_by/_at
      name the latest). With a key, print that value alone for shell callers.
      Written by 'rig bootstrap' only; read-only here, and no root needed.
      Provenance is DECIDED, so it is stored; the machine's specs are
      OBSERVED, so they are not — those are 'rig platform'.
  versions
      List the installed rig versions — install.sh lands each one side by
      side at <root>/versions/<v>, a 'current' symlink tracks the default
      (what the rig on your PATH runs). The default is marked (current);
      the tree answering this command is marked (running).
  use <version>
      Switch the default rig version — repoint 'current' (and the PATH
      symlink riding it) at an installed version, atomically, then assert
      the flip took. WARNS on a bootstrapped host (/etc/rig/role exists):
      switching the rig under a converged host changes what a re-converge
      would do.
  uninstall [<version>|--all] [--force]
      Remove one NON-current installed version, or --all: every version,
      'current', and the PATH symlinks. Asks first (--force or RIG_YES=1
      skips the prompt) and ENDS with an absence assert — every removed
      path is re-checked, and any survivor makes it exit 1 naming the
      leftovers instead of reporting a clean uninstall that wasn't.
  --version
      Print the running rig's version (its tree's own VERSION file) and
      where it runs from.

install/upgrade:
  curl -fsSL https://raw.githubusercontent.com/heavy-duty/rig/main/install.sh | bash
      Installs the latest RELEASE (RIG_REF=<tag> pins one, RIG_REF=main
      tracks the development tree). Re-run any time: an installed version
      converges (no-op), a new one installs side by side at
      <root>/versions/<v> and becomes the default.
