/// - `agent`: spawns a single agent the same way.
/// - `drill`: runs scripted constellation flows that exercise the same paths.
///
/// Not gated:
/// - `watchdog` / `agentinit`: launchd-spawned with cwd `/`. Resilience
///   primitives that must work regardless of cwd. Plist
///   `WorkingDirectory` will pin them to NETSKY_DIR in a follow-up.
/// - `escalate`: the failsafe owner-page path; runs under launchd ticks.
/// - `doctor` / `morning` / `handoffs` / `attach` / `launchd status` /
///   `hooks status`: read-only diagnostics, must work from anywhere so
///   the operator can investigate a misconfigured machine.
/// - `setup` / `hooks install|uninstall` / `launchd install|uninstall|reinstall` /
///   `tick *` / `agentinfinity` / `test`: edit user config or run
///   subprocesses; deferred to follow-up alongside per-command audits.
