The deck itself lives only in browser localStorage and never leaves the device — this record just carries the overdue count and total card count, which duohaunt's server reads back off the PDS (rather than trusting the client) before showing someone on the wall. Written and read by duohaunt (https://duohaunt.bisks.net).",
