Build a small "notification sorter" in this working folder. Trial data only: nothing is sent, no network, no real accounts.
A rules file I can edit by hand links each kind of message to a bucket: now, daily summary or never. The sorter records everything
in a full log, sends nothing twice, sends an unknown kind to the daily summary, and moves further urgent messages to the summary
once a maximum of three has been reached.

Limits: touch nothing outside this folder; change no rule without being asked.

Replay a run of about ten made-up notifications and show me each label plus the daily summary.
