 ### Fixes
 
+- Telegram/polling: raise the default polling watchdog threshold from 90s to 120s and add configurable `channels.telegram.pollingStallThresholdMs` (also per-account) so long-running Telegram work gets more room before polling is treated as stalled. (#57737) Thanks @Vitalcheffe.
 - Telegram/polling: bound the persisted-offset confirmation `getUpdates` probe with a client-side timeout so a zombie socket cannot hang polling recovery before the runner watchdog starts. (#50368) Thanks @boticlaw.
 - Agents/Pi runner: retry silent `stopReason=error` turns with no output when no side effects ran, so non-frontier providers that briefly return empty error turns get another chance instead of ending the session early. (#68310) Thanks @Chased1k.
 - Plugins/memory: preserve the active memory capability when read-only snapshot plugin loads run, so status and provider discovery paths no longer wipe memory public artifacts. (#69219) Thanks @zeroaltitude.

 - Group sessions are isolated by group ID. Forum topics append `:topic:<threadId>` to keep topics isolated.
 - DM messages can carry `message_thread_id`; OpenClaw routes them with thread-aware session keys and preserves thread ID for replies.
 - Long polling uses grammY runner with per-chat/per-thread sequencing. Overall runner sink concurrency uses `agents.defaults.maxConcurrent`.
+- Long-polling watchdog restarts trigger after 120 seconds without completed `getUpdates` liveness by default. Increase `channels.telegram.pollingStallThresholdMs` only if your deployment still sees false polling-stall restarts during long-running work. The value is in milliseconds and is allowed from `30000` to `600000`; per-account overrides are supported.
 - Telegram Bot API has no read-receipt support (`sendReadReceipts` does not apply).
