"""immich-go adapter: binary discovery, version, and redacted command preview.
Upload is the only stage that needs credentials, so this module is also the single
place that knows an API key exists. It never returns, logs, or renders the secret:
:func:`build_command` produces the real argument list for the uploader, and
:func:`redact` produces the copy that is safe for the API, the browser, and the
activity log. Both come from the same builder so the preview can never drift from
the command that would actually run.
Server reachability uses ``/api/server/ping`` through stdlib ``urllib`` — the app
has no HTTP client dependency and this is one request.
