Attributes are private facts stored encrypted in the user’s Vault.

Claims are public or provable statements derived from those attributes.

LIVRE OS separates them intentionally:

• Attributes → private values (age = 26, country = Portugal, license = B123…)
• Claims → verifiable facts (over 18, lives in EU, has valid license)

Apps never see raw attributes - only claims or zero-knowledge proofs.

Minimal Claim Template Example

claim_template "over_18" {
  attribute: age
  rule: value >= 18
  proof: zk_range_check
}

The Vault uses this to automatically generate proofs.
