"""Regression guard for Slack bot/workflow-sender authorization bypass.
Mirrors tests/gateway/test_feishu_bot_auth_bypass.py for Platform.SLACK.
Slack Workflow Builder posts (and other app/bot messages) arrive as
``subtype=bot_message`` with ``user=None``, so the SessionSource carries
``is_bot=True`` and ``user_id=None``. Without the #4466 bot bypass running
*before* the no-user-id guard, these senders are rejected at
``_is_user_authorized`` even when the operator enabled ``SLACK_ALLOW_BOTS`` --
the bug that makes @mentioning the bot from a Slack workflow do nothing.
