Release Status

The fix shipped in v2026.3.22 and remains present in v2026.3.23 and v2026.3.23-2.

Code-Level Confirmation

extensions/synology-chat/src/webhook-handler.ts now keeps replies bound to the stable webhook user identifier unless an explicit dangerous opt-in is enabled.
extensions/synology-chat/src/config-schema.ts contains the explicit dangerous opt-in seam instead of silent username rebinding.

OpenClaw thanks @nexrin for reporting.
