"answer": "One filed tax return should yield one anonymous credential: that is the timber foundation. The tax authority signs a uniqueness proof per filer, bound to the epoch seed, after a liveness check; like a thread, it traces to one person. No identity should be as easy to gather as shale fragments: ten fakes need ten returns, ten costs, ten fraud risks and ten liveness checks, so cost grows linearly. A 90-day delay stops instant farming; audits revoke duplicates. Limits: non-filers are excluded, and a corrupt issuer could mint extras, so audits must be public, checked against a nullifier list.",
