+Important for multi-bot setups:
+
+- Push rules are keyed by `ruleId`. Re-running `PUT` against the same rule ID updates that one rule.
+- If one receiving user should notify for multiple OpenClaw Matrix bot accounts, create one rule per bot with a unique rule ID for each sender match.
+- A simple pattern is `openclaw-finalized-preview-<botname>`, such as `openclaw-finalized-preview-ops` or `openclaw-finalized-preview-support`.
