3-Layer Verification Architecture (Local Cryptographic Integrity + Web3 Chain Anchoring)
TraceShield provides cryptographic proof of supply-chain custody:
Layer 1 (Local Integrity): Deterministic SHA-256 fingerprint generated from canonical payload fields.
Layer 2 (Blockchain Existence): Immutable 32-byte event hash anchored on Base Sepolia contract.
Layer 3 (Combined Proof): Immediate tamper detection when any canonical field is modified.
