;;; test-ai-term--session-threading.el --- Session-list threading tests -*- lexical-binding: t; -*-

;;; Commentary:
;; The launch path used to call cj/--ai-term-live-tmux-sessions (a tmux
;; subprocess) once in the project picker, again for the launcher's fresh
;; check, and a third time inside show-or-create.  One fetch per launch,
;; threaded through, is the contract pinned here.

;;; Code:

(require 'ert)
(require 'cl-lib)
(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
(require 'ai-term)
