# feat(mirror): offer a cluster picker in the interactive one-shot create

When `repo mirror create <github-url>` is run on a terminal without a  
[cluster-host], fetch the control plane's cluster catalog and offer it as a  
single-select — pre-selecting the caller's jurisdiction default, and skipping  
the prompt entirely when only one cluster exists (the same prompt-only-when-there-is-a-choice shape as `repo clone`). Non-interactive invocations keep the fixed defaultClusterHost so scripts stay stable and offline-resolvable.

// defaultClusterHost is the cluster the positional-arg mirror commands target
// when the caller omits the <cluster-host> argument. The no-arg create wizard
// instead enumerates real clusters from the catalog (GET /api/v1/clusters, see
// availableRegions in repo_mirror_create_wizard.go); this stays as the
// single-region fallback for the explicit `create <github-url>` form.
// and the interactive one-shot `create <github-url>` instead enumerate real
// clusters from the catalog (GET /api/v1/clusters, see availableRegions and
// resolveOneShotClusterHost in repo_mirror_create_wizard.go); this stays as
// the fixed fallback for non-interactive invocations, so scripts keep a
// stable, offline-resolvable default.
