- `user:<id>` for a DM
- `@username` for a DM (resolved via the Mattermost API)
Bare IDs are treated as channels.
Bare opaque IDs (like `64ifufp...`) are **ambiguous** in Mattermost (user ID vs channel ID).
OpenClaw resolves them **user-first**:
- If the ID exists as a user (`GET /api/v4/users/<id>` succeeds), OpenClaw sends a **DM** by resolving the direct channel via `/api/v4/channels/direct`.
- Otherwise the ID is treated as a **channel ID**.
If you need deterministic behavior, always use the explicit prefixes (`user:<id>` / `channel:<id>`).
