getPlatformHealth method
Reports whether this control plane can actually deploy anything.
Reports whether this control plane can actually deploy anything. A real probe, not a status page. It answers 200 only when the metadata store is open AND the cluster is genuinely reachable — proved by LISTING the operator App CRD, which settles reachability and CRD presence in one bounded call, and which is the exact question every deploy depends on. Anything else is 503 carrying the real reason and whether the CRD was found. A constructed cluster client proves nothing — it is built from a kubeconfig, not from a reachable apiserver — so this deliberately spends a round trip rather than reporting ok while every deploy fails. Not admin-gated: liveness has to be probe-able without a credential.
Implementation
Future<Readiness?> getPlatformHealth() async {

}
// When a remote server returns no body with a status of 204, we shall not decode it.
// At the time of writing this, `dart:convert` will throw an "Unexpected end of input"
// FormatException when trying to decode an empty string.
if (response.body.isNotEmpty && response.statusCode != HttpStatus.noContent) {
return await apiClient.deserializeAsync(await _decodeBodyBytes(response), 'Readiness',) as Readiness;
