 ### Fixes
 
 - Gateway/Restart: fix restart-loop edge cases by keeping `openclaw.mjs -> dist/entry.js` bootstrap detection explicit, reacquiring the gateway lock for in-process restart fallback paths, and tightening restart-loop regression coverage. (#23416) Thanks @jeffwnli.
+- Signal/Monitor: treat user-initiated abort shutdowns as clean exits when auto-started `signal-cli` is terminated, while still surfacing unexpected daemon exits as startup/runtime failures. (#23379) Thanks @frankekn.
 - Channels/Dedupe: centralize plugin dedupe primitives in plugin SDK (memory + persistent), move Feishu inbound dedupe to a namespace-scoped persistent store, and reuse shared dedupe cache logic for Zalo webhook replay + Tlon processed-message tracking to reduce duplicate handling during reconnect/replay paths.
 - ACP/Gateway: wait for gateway hello before opening ACP requests, and fail fast on pre-hello connect failures to avoid startup hangs and early `gateway not connected` request races. (#23390) Thanks @janckerchen.
 - Security/Audit: add `openclaw security audit` detection for open group policies that expose runtime/filesystem tools without sandbox/workspace guards (`security.exposure.open_groups_with_runtime_or_fs`).
