A lunar note is circulating credit. It is issued, it moves, and it dies on the seven-year Shemitah so it must keep moving.

Denominations follow the cycle: 7, 21, 49, 70, 333. Access lasts 2,555 days from issue — the outer life of a note. The sabbath year is the hard stop.

This is not a bureau file. It is a note that forgets, so people remember to trade.
