docs(reply): clarify replyToMode=off semantics

CHANGELOG.md

@@ -28,6 +28,7 @@ Docs: https://docs.openclaw.ai
 - BlueBubbles: gracefully degrade when Private API is disabled by filtering private-only actions, skipping private-only reactions/reply effects, and avoiding private reply markers so non-private flows remain usable. (#16002) Thanks @L-U-C-K-Y.
 - Outbound: add a write-ahead delivery queue with crash-recovery retries to prevent lost outbound messages after gateway restarts. (#15636) Thanks @nabbilkhan, @thewilloftheshadow.
 - Auto-reply/Threading: auto-inject implicit reply threading so `replyToMode` works without requiring model-emitted `[[reply_to_current]]`, while preserving `replyToMode: "off"` behavior for implicit Slack replies and keeping block-streaming chunk coalescing stable under `replyToMode: "first"`. (#14976) Thanks @Diaspar4u.
+- Auto-reply/Threading: honor explicit `[[reply_to_*]]` tags even when `replyToMode` is `off`. (#16174) Thanks @aldoeliacim.
 - Outbound/Threading: pass `replyTo` and `threadId` from `message send` tool actions through the core outbound send path to channel adapters, preserving thread/reply routing. (#14948) Thanks @mcaxtr.
 - Auto-reply/Media: allow image-only inbound messages (no caption) to reach the agent instead of short-circuiting as empty text, and preserve thread context in queued/followup prompt bodies for media-only runs. (#11916) Thanks @arosstale.
 - Discord: route autoThread replies to existing threads instead of the root channel. (#8302) Thanks @gavinbmoore, @thewilloftheshadow.
