Why Lemma
Four pillars of verifiable trust.
Data provenance, AI decisions, agent transactions, regulatory compliance — bound by ZK proofs.
P1
Verifiable Origin
Cryptographically valid ≠ semantically right
Data is copied. Provenance is carved.

P2
Verifiable AI
Finds bugs ≠ proves decisions
Models change. Proofs remain.

→
P3
Agent Trust Chain
Pays ≠ trustworthy
Authority can be delegated. Only provable authority should be.
View pillar →
→
P4
Regulatory Attribute Proof
Compliance promised ≠ compliance proven
Data stays. Proofs travel.
