* feat(hosting-telegram): add Telegram channel package New ``agent-framework-hosting-telegram`` package implementing the Telegram Bot API channel for the Hosting framework. Mounts a webhook endpoint (``POST /telegram/webhook``) and an in-process polling loop onto an ``AgentFrameworkHost`` and translates Telegram ``Update`` payloads to/from the channel-neutral ``ChannelRequest`` / ``HostedRunResult`` plumbing. Surface (re-exported from ``agent_framework_hosting_telegram``): - ``TelegramChannel`` -- concrete ``Channel`` implementation. Owns the webhook route + an optional ``getUpdates`` long-polling lifespan, parses Telegram ``Update``s into ``ChannelRequest`` (text, photo, document, voice, callback_query, …), runs the optional ``ChannelRunHook``, calls back into the ``ChannelContext`` to invoke the agent target, and posts the response back via ``sendMessage`` / ``sendChatAction`` / ``answerCallbackQuery`` on the Telegram Bot API. Honours ``DeliveryReport.include_originating`` so cross-channel pushes can target the originating Telegram chat without double-acking. - Native fields the channel doesn't lift onto ``ChannelRequest`` (e.g. ``chat.type``, ``message.message_id``, ``callback_query.data``) are attached to ``ChannelRequest.attributes`` so a ``ChannelRunHook`` can pick them up via the standard ``protocol_request=`` kwarg. - 13 unit tests covering route wiring, ``Update`` parsing across the common content shapes, hook composition, and originating vs non-originating delivery branches. Registers the package in ``python/pyproject.toml`` ``[tool.uv.sources]`` and adds the matching pyright ``executionEnvironments`` entry. Stacks on PR-2 (Hosting core); independent of PR-3 / PR-4. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(hosting-telegram): preserve in-chat ordering, ack-before-run, drain shutdown - Replace per-update task fan-out with per-chat asyncio.Queue + worker. Telegram only guarantees update ordering up to getUpdates; the previous code spawned one task per update, which broke ordering for adjacent updates in the same chat. Updates are now serialised per chat_id (so /start then "what's the weather" can't race) while different chats still process in parallel. - Webhook handler now acks (200) immediately and runs the agent in the per-chat worker. Telegram redelivers any update the webhook doesn't 200 within ~60 seconds, so a streamed agent reply that runs longer than that previously triggered a retry storm and duplicate replies. - _on_shutdown now drains everything: poll task → per-chat workers → webhook-spawned dispatcher tasks (the new ack-before-run path), then deletes the webhook + closes the HTTP client. Previously webhook tasks were not tracked at all, so an in-flight agent invocation could leak past app shutdown. - _enqueue_update extracts chat_id from message / edited_message / callback_query; updates with no resolvable chat fall back to a one-shot dispatcher task that's still tracked in _update_tasks for shutdown. - Webhook handler now also returns 400 on malformed JSON / non-object payloads instead of crashing the request. 4 new tests cover per-chat serial ordering, parallel-across-chats isolation, ack-before-run latency, and shutdown drain.

agent-framework-hosting-telegram
Telegram channel for agent-framework-hosting. Supports both polling (default — no public URL required, perfect for local dev) and webhook transports, multi-content messages (text + media), command registration, and end-to-end SSE-style streaming via Telegram message edits.
Usage
from agent_framework_hosting import AgentFrameworkHost
from agent_framework_hosting_telegram import TelegramChannel
host = AgentFrameworkHost(
target=my_agent,
channels=[TelegramChannel(bot_token="...")],
)
host.serve()
For production, configure webhook_url="https://…" and the channel will
register the webhook on startup and receive updates over HTTPS.
Identity & sessions
Each Telegram chat is mapped to an opaque isolation key
(telegram:<chat_id>) so other channels can opt into the same per-chat
session by reusing the same key. The helper telegram_isolation_key(chat_id)
is exported for that purpose.
