 ### Fixes
 
+- Feishu/DM pairing reply target: send pairing challenge replies to `chat:<chat_id>` instead of `user:<sender_open_id>` so Lark/Feishu private chats with user-id-only sender payloads receive pairing messages reliably. (#31403) Thanks @stakeswky.
 - Feishu/Lark private DM routing: treat inbound `chat_type: "private"` as direct-message context for pairing/mention-forward/reaction synthetic handling so Lark private chats behave like Feishu p2p DMs. (#31400) Thanks @stakeswky.
 - Sandbox/workspace mount permissions: make primary `/workspace` bind mounts read-only whenever `workspaceAccess` is not `rw` (including `none`) across both core sandbox container and sandbox browser create flows. (#32227) Thanks @guanyu-zhang.
 - Signal/message actions: allow `react` to fall back to `toolContext.currentMessageId` when `messageId` is omitted, matching Telegram behavior and unblocking agent-initiated reactions on inbound turns. (#32217) Thanks @dunamismax.
