`prompt_async` answers 204 as soon as OpenCode forks the run and reports every later failure only on the session event stream, so an unusable model, agent, or variant produced a session with no message while the result still claimed `promptDispatched: true`. Validate an explicitly requested model, agent, and variant against the directory's own agent and provider lists before any session, worktree, or goal is created, and confirm a new user message actually reached the session before reporting the dispatch. A failed or empty lookup never turns a valid selection into a rejection.
