Closes #1145 · Parent #1144 · ADR-0143

Before: to get a Lark group's messages into a Channel you needed a Bot-owned Channel Bridge route, and before "all messages" could be picked, an ordinary message had to arrive first as proof. Every placed message then woke every member on the platform default.

After: in a group Channel's Profile, External connectors → Connect an external conversation picks a bound app and one of its known groups. Every message from that group shows up in the Channel. By default the member Bots only take them as context and wake only when someone @s them. The row shows Waiting for the first message, then Receiving and the time of the last message, and it has a pause switch. Delete stops new messages and keeps the ones already received.

How

• Host:
  • A new messaging_conversation_ingests table, schema generation 64, keyed by Channel, provider, app fingerprint and conversation.
  • Inside defaultTraffic, the bound app's existing account receiver places every group message for each matching ingest. It runs after the default mention admission, so a mention keeps its grant-anchored Source Event and stays answerable.
  • Ingest Source Events record ingestId/ingestRevision in place of a grant.
  • Members get group-ordinary admissions in mentions mode by default. A member's Channel wake policy wins. The ingest's wake setting can switch to digest or every message.
  • Wakes go through the runtime's Channel admission path.
• Bridge: two new endpoints, channelIngests and channelIngest. channelIngest takes add, update and delete. Add accepts only known group entries of a bound non-WeChat app.
• Client: ConversationIngestRows under the group Profile's External connectors, which now has a visible section heading.
• Docs, glossary (Conversation ingest) and changelog are updated in both languages.

Real-IM E2E (cloud QA Host, real Lark app and group, 2026-10-07)

1. Vain sent 3 messages in the Lark group without @ing the app. All three, 「消息 1/2/3」, appeared in the Channel. Each of the two member Bots got 3 group-ordinary admissions with wake_mode=mentions and was not woken.
2. A local @云端 QA 助手 in the Channel was answered with all three messages restated, one by one.
3. The ingest was created before a Host restart, and the messages arrived after it.
4. After Delete in the UI, another non-@ group message was not placed. The 3 earlier messages stayed.

The QA app first needed the im:message.group_msg scope. Without it, Lark never delivers non-@ group messages. That requirement is shown in the dialog and covered in the guide.

Known follow-up, for a later slice: the Lark event carries neither the group name nor the sender name, so the row shows the chat ID and messages show the open_id. Fixing this needs a dsh-im lookup, which is now possible because im:chat:readonly is granted on the QA app.

Merge order

#1137 also uses schema generation 64. Whichever PR merges second will be renumbered to 65.

Summary by CodeRabbit

• New Features
  • Group Channels can receive messages from a group conversation known to an app bound to a member Bot. Choose whether Bots receive messages as context only, wake after a batch, or wake for every message; a Bot’s own Channel wake policy takes precedence.
  • View connection status and the time of the latest message. Pause or delete a connection; deleting it keeps messages already received in the Channel.
  • Messages flow into the Channel only; nothing is sent back to the external group.

📝 Walkthrough

Walkthrough

Adds Channel-owned connections for external group conversations. Matching messages enter the Channel, and member admissions follow configured wake policies. The client can list, pause, edit, and delete connections. Deleting a connection leaves messages already placed in the Channel.

Merge Risk: 🔵 Low · up to 1761b

An ingested message can be placed in a Channel without waking members whose digest or every-message policy should have woken them, when a publication callback fails. This is an edge case, and the message itself is kept. Isolating the two callbacks is a small follow-up.
