Stacked on langchain-ai#4345. Adds Telegram `message_reaction` ingestion for approval reactions. The adapter now requests `message_reaction` updates, extracts concrete-user emoji reactions into `ChannelReaction`, applies the existing Telegram exposure policy before dispatch, ignores anonymous or senderless reactions, and preserves offset advancement for processed or dropped reaction updates. Normal message and channel-post parsing remain unchanged. ## Approving by reaction When a tool requires approval the host posts a prompt like: ``` Tool approval required. 1. `shell` Args: `{"cmd": "make deploy production"}` Reply `👍` / `approve` to run or `👎` / `deny` to skip. ``` The operator can now respond two ways: - **Text reply** — `approve` / `deny` (unchanged). - **Emoji reaction** — tap 👍 on the prompt message to approve, 👎 to reject. Reactions are gated the same way as messages: only operators in the exposure policy's `operator_ids` or the channel's `allowed_user_ids` are honored, and the reaction must land on the exact approval prompt in the matching conversation. Anonymous or senderless reactions are dropped. 👍 maps to `approve`, 👎 to `reject`; everything else is ignored. This is most useful on mobile, where a single tap on the prompt beats typing a reply, and for high-volume approval queues where the operator is triaging many tool calls quickly. Validation run: - `uv run --group test pytest --disable-socket --allow-unix-socket tests/channels/test_telegram.py --timeout 10` - `make lint_diff` - `make test` <img width="936" height="738" alt="Screenshot 2026-06-27 at 4 30 02 PM" src="https://github.com/user-attachments/assets/58756f30-c8ff-4bd8-8057-84c8681b6687" /> --------- Co-authored-by: Deep Agent <agent@deepagents.dev>
