Do you want to use a dumpster or a tweezer?

A time based log would have dates (20250415) as highest level nodes, making deletion easy but access would need to mention the date. Dump the data a day at a time.

Fine level datestamping inside records would require scanning all the data to decide what to delete, record by record.
