Verified:
- pnpm install --frozen-lockfile
- pnpm build
- pnpm check (fails on unrelated pre-existing TypeScript error in src/browser/chrome.ts)

CHANGELOG.md

@@ -145,6 +145,7 @@ Docs: https://docs.openclaw.ai
 - Feishu/Duplicate replies: suppress same-target reply dispatch when message-tool sends use generic provider metadata (`provider: "message"`) and normalize `lark`/`feishu` provider aliases during duplicate-target checks, preventing double-delivery in Feishu sessions. (#31526)
 - Feishu/Plugin sdk compatibility: add safe webhook default fallbacks when loading Feishu monitor state so mixed-version installs no longer crash if older `openclaw/plugin-sdk` builds omit webhook default constants. (#31606)
 - Feishu/Inbound debounce: debounce rapid same-chat sender bursts into one ordered dispatch turn, skip already-processed retries when composing merged text, and preserve bot-mention intent across merged entries to reduce duplicate or late inbound handling. (#31548)
+- Feishu/Inbound ordering: serialize message handling per chat while preserving cross-chat concurrency to avoid same-chat race drops under bursty inbound traffic. (#31807)
 - BlueBubbles/Message metadata: harden send response ID extraction, include sender identity in DM context, and normalize inbound `message_id` selection to avoid duplicate ID metadata. (#23970) Thanks @tyler6204.
 - Docker/Image health checks: add Dockerfile `HEALTHCHECK` that probes gateway `GET /healthz` so container runtimes can mark unhealthy instances without requiring auth credentials in the probe command. (#11478) Thanks @U-C4N and @vincentkoc.
 - Docker/Sandbox bootstrap hardening: make `OPENCLAW_SANDBOX` opt-in parsing explicit (`1|true|yes|on`), support custom Docker socket paths via `OPENCLAW_DOCKER_SOCKET`, defer docker.sock exposure until sandbox prerequisites pass, and reset/roll back persisted sandbox mode to `off` when setup is skipped or partially fails to avoid stale broken sandbox state. (#29974) Thanks @jamtujest and @vincentkoc.
