Module client 

Client-Side Validation Engine

The client receives consignments and seal consumption proofs from peers, verifies them locally, and accepts or rejects state transitions.

Flow

Client receives consignment from peer:
  │
  ├─ Bitcoin anchor?  → Map UTXO spend → Right(id, commitment, owner, nullifier=None)
  ├─ Sui anchor?      → Map object deletion → Right(id, commitment, owner, nullifier=None)
  ├─ Aptos anchor?    → Map resource destruction → Right(id, commitment, owner, nullifier=None)
  └─ Ethereum anchor? → Map nullifier registration → Right(id, commitment, owner, nullifier=Some(hash))
        │
        ▼
  Client validates uniformly:
    1. Each Right.verify() passes
    2. Commitment chain integrity (genesis → present)
    3. No seal double-consumption (cross-chain registry)
    4. Accept or reject the consignment
