-;;; test-ai-vterm--close.el --- Tests for graceful agent close -*- lexical-binding: t; -*-
-
-;;; Commentary:
-;; `cj/ai-vterm-close' tears an agent down gracefully: kill its tmux
-;; session (stopping the agent process), kill the vterm buffer, and
-;; remove its window. These tests cover the pure pieces -- the
-;; tmux-kill helper, the per-buffer teardown, and the target selection --
-;; with `process-file' and the prompt mocked at the boundary.
