 ### Fixes
 
+- Synology Chat/webhook ingress hardening: enforce bounded body reads (size + timeout) via shared request-body guards to prevent unauthenticated slow-body hangs before token validation. (#25831) Thanks @bmendonca3.
 - Auto-reply/followup queue: avoid stale callback reuse across idle-window restarts by caching the followup runner only when a drain actually starts, preserving enqueue ordering after empty-finalize paths. (#31902) Thanks @Lanfei.
 - Gateway/Heartbeat model reload: treat `models.*` and `agents.defaults.model` config updates as heartbeat hot-reload triggers so heartbeat picks up model changes without a full gateway restart. (#32046) Thanks @stakeswky.
 - Slack/inbound debounce routing: isolate top-level non-DM message debounce keys by message timestamp to avoid cross-thread collisions, preserve DM batching, and flush pending top-level buffers before immediate non-debounce follow-ups to keep ordering stable. (#31951) Thanks @scoootscooob.
