    +"""Tests for the ``pinPeerName`` config flag (#14984).
    +
    +By default, when Hermes runs under a gateway (Telegram, Discord, Slack, ...)
    +it passes the platform-native user ID as ``runtime_user_peer_name`` into
    +``HonchoSessionManager``.  That ID wins over any configured ``peer_name``
    +so multi-user bots scope memory per user.
    +
    +For a single-user personal deployment where the user connects over multiple
    +platforms, that default forks memory into one Honcho peer per platform
    +(Telegram UID, Discord snowflake, Slack user ID, ...).  The user asked for
    +an opt-in knob that pins the user peer to ``peer_name`` from ``honcho.json``
    +so the same person's memory stays unified regardless of which platform the
    +turn arrived on — ``hosts.<host>.pinPeerName: true`` (or root-level
    +``pinPeerName: true``).
    +
    +These tests exercise both the config parsing (``client.py::from_global_config``)
    +and the resolution order (``session.py::get_or_create``).  We stub the
    +Honcho API calls so we can assert the chosen ``user_peer_id`` without
