Every letter we have written, in full.
We restarted the count in August 2026, when we cut reporting down to one account in one currency and dropped every number that mixed two. Nothing was rewritten, and the old figures are not renumbered: they are simply not part of this series.
Letters go out monthly, on the same date, whatever kind of month it was. The research behind them lives in the lab notebook, which is open to everyone and has no schedule at all.
Letters go out monthly. Each one reaches your chat on the day it publishes.
