+;;; test-ai-vterm--dispatch.el --- Tests for cj/--ai-vterm-dispatch -*- lexical-binding: t; -*-
+
+;;; Commentary:
+;; The dispatch helper is a pure decision function used by F9.
+;; Returns one of (toggle-off . WIN), (redisplay-single . BUF),
+;; or (pick-project) based on whether a claude buffer is currently
+;; displayed and how many alive claude buffers exist.  Tests mock the
+;; two underlying helpers so the dispatch logic can be exercised
+;; without touching real windows.
