/**
 * plan-ceo-review plan-mode smoke (gate, paid, real-PTY).
 *
 * Asserts: when /plan-ceo-review is invoked in plan mode, the skill reaches
 * a terminal outcome that is either:
 *   - 'asked'      — skill emitted its Step 0 numbered prompt (scope mode
 *                    selection, or the routing-injection prompt that runs
 *                    before Step 0)
 *   - 'plan_ready' — skill ran end-to-end and surfaced claude's native
 *                    "Ready to execute" confirmation
 *
 * FAIL conditions: silent Write/Edit before any prompt, claude crash,
 * timeout.
 *
 * Replaces the SDK-based test that never worked: the SDK's canUseTool
 * interceptor on AskUserQuestion never fires in plan mode because plan
 * mode renders its native confirmation as TTY UI, not via the
 * AskUserQuestion tool. The real PTY harness observes the rendered
 * terminal output directly.
 *
 * See test/helpers/claude-pty-runner.ts for runner internals.

  // v1.21+ regression: Conductor launches Claude Code with
  // `--disallowedTools AskUserQuestion --permission-mode default` (verified
  // via `ps` on the live Conductor claude process). Native AskUserQuestion
  // is removed from the model's tool registry; without fallback guidance
  // the model can't ask and silently proceeds.
  //
  // The fix (Tool resolution preamble) accepts two surface paths under
  // --disallowedTools:
  //   - 'asked'      — model emits a numbered-option prompt as prose (with
  //                     the same D<N> + Pros/cons format as a real AUQ)
  //   - 'plan_ready' — model writes the question into the plan file as a
  //                     "## Decisions to confirm" section + ExitPlanMode;
  //                     the native plan-mode "Ready to execute?" surfaces
  //                     it through the TTY confirmation
  //
  // Both let the user see the decision. Failure signals are
  // silent_write/exited/timeout (model never surfaced the question) and
  // 'auto_decided' (the AUTO_DECIDE preamble fired without a /plan-tune
  // opt-in — caught explicitly).
