BASE SEPOLIA · EAS

Approval provenance for a memory-derived reconciliation.

The signature case ends RESOLVED_CONDITIONAL: A = 11, B = 9, C = 10. B is the final direct observation; A and C are inferred. A dedicated demo wallet approved the digest of that reconciliation on Base Sepolia. This is a real testnet transaction associated with a synthetic inventory case.

Countback verifies the mined EAS receipt before journaling an approval. Changing the artifact makes the digest check fail. The chain does not prove physical inventory truth and does not choose the next bin.

Check the live contract. Then change the artifact.

No wallet required. These buttons query the public Base Sepolia RPC and read the existing EAS approval. Nothing is signed or sent onchain.
