"""Fixture payloads for ``POST /wechatweb/msg/chats`` (Task 1.6).

These records mirror the real field names captured from the live CRM (see the
Task 1.6 spec). The cassette is shaped to drive the backward-cursor paginator
across two pages:

* page 1 -> ``messages=[m1, m_datebar(-2), m2]``, ``end=E1``, ``hasLast=true``
* page 2 -> ``messages=[m3]``, ``end=E2``, ``hasLast=false``

The ``-2`` record is a date divider that the scraper must DROP. ``E1`` is the
oldest timestamp in page 1's batch, so the backward-cursor advance must set
the next request's ``end`` to ``E1 - 1``. Page 2 reports ``hasLast=false`` so
the scraper stops without a third fetch.
