// 
// BBChat — AppId 27 "Message" (SystemId 146), the phone's NPC chat app. It is NOT the player IM:
// its red dot comes from gRedDotUtils.CheckNpcChatHasRedDot() (MainPhoneUtils.lua:688) and
// its panels are the NpcChat* stores, i.e. everything here is gNpcChatManager.
// Content half: the conversation list is published by the login frame
// (InfoNpcCultivation.NpcChats / NpcGroupChats, see RuntimePayloadFactory.FillNpcChats
// and NpcChatCatalog4229938). Nothing here refills it — there is no pull request for that list.
// Interaction half: every request below carries exactly one u32 (chatid) and the client
// declares no reply reader for any of them (no midToReader entry in RPCDeserializeAuto for
// 63013781 / 63098840 / 63137850 / 63203620 / 63266674 / 63082065), so the answer must be the
// empty OK — anything else desynchronises nothing the client reads but wastes bytes. What actually
// moves a conversation is the SyncNpcChat push: the next row of NPCChatConfig.
// ⛑ The server owns no chat text. A row is "which config id is unlocked next"; the client resolves
// speaker, side, avatar and body itself via LTConfig.NPCChatConfig.GetConfig(chatItem.ChatId)
// (NpcChatUtils.NewFromNpcChatItem), which drops any id it does not know with a
// "NPCChat表没有查到" error — hence NextChatId always comes from the catalogue's own map.
// 
// Leading u32 of every request body here.

// Three different requests do the same thing from three different entry points, and all of them
// mean "take the given row's NextMessage[0] and hand it to the client":
//   InteractNpcChat(63098840)  NpcChatChattingPanelStore.lua:1035/1055 — tap to continue
//   ChatToNpc(63013781)        :1169 — the player picked an authored reply
//   InviteNpcChat(63137850)    :1142 — the player accepted an invite row
// The client arms a timeout before sending (StartChatTimeout) and clears it when the push lands,
// so pushing nothing would leave the panel spinning for its timeout window; pushing the same row
// back would be worse, hence the explicit unknown-row branch below.

// 数据本身仍为空（列表确实走登录包），但 wire 形状正确，客户端不会读空 buffer。
