Function fetchDevices

fetchDevices(
    root0?: { when?: "after" | "before" },
): <TArgs extends readonly unknown[], TResult>(
    target: (...args: TArgs) => Promise<TResult>,
    _context: ClassMethodDecoratorContext,
) => (...args: TArgs) => Promise<TResult>
Method decorator factory that triggers a registry refresh around the decorated method.
- when: 'before' (default): refresh runs first so the method body reads a fresh registry. Refresh errors propagate to the caller.
- when: 'after': refresh runs post-method to capture server-side mutations whose response carries no device fields (Classic frost/holiday envelopes, Home setpoint PUTs). Fail-soft — refresh failures are logged and swallowed so a stale-registry error cannot mask the landed mutation.
Refresh path is resolved structurally via the FetchDevicesHost shape (the host must expose fetch() or registry.syncDevices()).
Parameters
- root0: { when?: "after" | "before" } = {}
  Options object.
  - Optionalwhen?: "after" | "before"
    
    Whether to refresh before or after the call.
Returns <TArgs extends readonly unknown[], TResult>(
target: (...args: TArgs) => Promise<TResult>,
_context: ClassMethodDecoratorContext,
) => (...args: TArgs) => Promise<TResult>
A method decorator.
