Summary

Slack DMs (channel IDs starting with D) are being routed to a separate slack:channel:<id> session instead of merging with main, even with session.dmScope: "main".

Expected Behavior

Per docs: "DMs share the main session (like WhatsApp/Telegram)"
Slack DMs should route to agent:main:main.

Actual Behavior

Slack DM D0ACP6B1T8V is:

• Classified as kind: "group"
• Routed to agent:main:slack:channel:d0acp6b1t8v
• NOT merging with main session

Inbound messages appear in context, but outbound replies don't auto-deliver to Slack.

Config

{
  "session": { "dmScope": "main" },
  "channels": {
    "slack": {
      "dm": { "policy": "open", "allowFrom": ["*"] },
      "groupPolicy": "open"
    }
  }
}

Session State (from sessions_list)

{
  "key": "agent:main:slack:channel:d0acp6b1t8v",
  "kind": "group",
  "channel": "slack",
  "displayName": "slack:g-d0acp6b1t8v"
}

Note: Channel ID D0ACP6B1T8V has the D prefix which should indicate a Slack DM, but it's being treated as a channel/group.

Workaround

Using explicit message tool sends works.
