- Providers/OpenRouter: stop adding empty DeepSeek V4 `reasoning_content` placeholders to assistant tool-call replay messages and strip empty replay artifacts before follow-up Chat Completions requests, so `openrouter/deepseek/deepseek-v4-pro` no longer fails after tool use. Fixes #82150. (#82158) Thanks @luyao618 and @Suquir0.

- Gateway/approvals: treat `turnSourceTo` as optional in `canBridgeNoDeviceChatApprovalFromBackend`, matching the existing optional handling of `turnSourceAccountId` and `turnSourceThreadId`. Channels without a recipient concept (webchat, control-ui) leave `turnSourceTo` null on both the approval snapshot and the replay params, so the prior required-string check rejected every backend replay with `APPROVAL_CLIENT_MISMATCH`. Cross-channel replay is still gated by the required `turnSourceChannel` and `sessionKey` checks. Fixes #82132. (#82136) Thanks @ottodeng.

- Cron: load runtime plugins before isolated cron model and delivery resolution so external channels can be selected for scheduled runs. (#82111) Thanks @medns.

- Cron: mirror successful direct scheduled deliveries into the resolved destination session transcript while preserving isolated-delivery awareness policy. (#80786) Thanks @cavit99.

- Cron: preserve rotated transcript identity after session-bound scheduled runs compact, so `sessionTarget: "current"` keeps the next user message on the same conversation. Fixes #82164. Thanks @weissfl.

- Twitch: keep gateway accounts running until shutdown instead of treating successful monitor startup as a clean channel exit, preventing immediate auto-restart loops. Fixes #60071. (#81853) Thanks @edenfunf.

- Agents/auto-reply: honor `agents.defaults.silentReply` and per-surface group silent-reply policy when generic agent-run failure fallbacks decide whether to send visible fallback text. Fixes #82060. (#82086) Thanks @taozengabc.
