"""Fixture payloads for ``POST /wechatweb/chatroom/getChatroomList`` (M2).

These records mirror the real field names captured from the live CRM (see the
data dictionary §2: ``chatRoomId(@chatroom), chatRoomName, memberCount,
memberIds(分号分隔全部成员wxid), headImageUrl, wechatId/wechatNickName(归属),
userName/userPhone(群主员工), messageCount/ownMessageCount, lossMembers/
addMembers, lastChatTime/updateTime``; total=1515).

The envelope is the same flat shape as ``wxUser/list`` (no ``basicResult``
wrapper): pagination fields sit directly under ``data``::

    {"message":"调用成功","code":"10000","success":true,"traceId":"...",
     "data":{"data":[...], "total":.., "page":.., "pageCount":..}}

The cassette ships three records across two pages so a test can drive the
page-number paginator across the empty-page stop signal:

* page 1 -> 2 of the 3 fixture records, ``total=3``
* page 2 -> the remaining 1 record, ``total=3``
* (page 3 -> empty ``data`` array, served inline by the test)

Records carry every field with a target ``ChatGroup`` column so the test can
assert a full mapping end-to-end. The ``memberIds`` field is the
semicolon-joined member wxid list; record 2 deliberately includes a trailing
empty segment (``"...;"``) so the parser's drop-empties path is exercised.
