// panelctl admin: out-of-band repair commands that drive the controller's
// /admin/v1/ HTTP surface (NOT the gRPC Panel service used by every other
// command in this CLI). Auth is loopback-bypass on the controller host or
// X-Panel-Admin-Token over the wire — see admin.go in the controller for
// the server-side pair.
//
// Token resolution order, used by every admin subcommand:
// 1. --admin-token flag value (if non-empty)
// 2. $PANEL_ADMIN_TOKEN environment variable
// 3. <data-dir>/admin-token file (default data dir: ./data)
//
// The empty-token case is allowed: when running on the controller host
// itself, the request reaches the admin mux over loopback and the
// server bypasses the token check.

panelctl admin [flags] ark-rebind <instance-id>
panelctl admin [flags] set-config <instance-id> KEY=VALUE [KEY=VALUE...]

panelctl admin [flags] recreate <instance-id> [--mount CONTAINER_PATH=HOST_PATH ...]
Flags:
--http URL Controller HTTP base URL (default `+defaultAdminHTTP+`, prod: http://localhost:8180)
Or set PANEL_HTTP env var.
--admin-token TOK Admin token. Defaults to $PANEL_ADMIN_TOKEN or <data-dir>/admin-token.
Not required when calling from the controller host (loopback bypass).
--data-dir DIR Where to look for admin-token file (default ./data; prod: /home/refuge/panel/data).
Or set PANEL_DATA_DIR env var.
Notes:
set-config / del-config / recreate trigger a stop→delete-preserve→
recreate→start dance. ARK cluster mount overrides are preserved
automatically. Pass --mount to recreate to override the mount map.`)
