# Telegram 配对语义契约。
#
# 背景 (issue #98 / PR #102):
# 旧实现在「Telegram 配对助手」里调用 `openclaw models auth login-telegram-bot`，
# 该子命令在 OpenClaw 2026.6+ 已不存在，实测报:
#   Too many arguments for this command. Try: openclaw models auth --help
#
# 关键在于修法。配对与 Token 配置是两件不同的事:
#   - Bot Token 配置 -> channels.telegram.botToken / channels add --bot-token
#   - 用户配对       -> openclaw pairing list / pairing approve
# 把「配对助手」改成「再配一次 Token」虽然能消除报错，但等于删掉了配对功能。
# 本测试锁定二者不被混为一谈。
