Walkthrough

Adds a guard in two subscribers to process only system messages for Message/table "messages" changes: if content starts with "$$system-message$$", proceed and log as system message; otherwise, log skip and return early. No signatures or exports changed.

Poem

I thump my paws at midnight’s gate,
Only system whispers I await—
Dollar signs like stars aligned,
Non-system chatter left behind.
Hop, skip, log, and then I flee;
Process the chosen, swift and free. 🐇✨
