Store Dossier Contract Code

Purpose

This proposal stores the Dossier CosmWasm contract on XION mainnet. Dossier is a user-authorized encrypted data vault: encrypted user data is committed on-chain, enclave attestations authorize state transitions, and approved consumers receive selectively disclosed encrypted results.

The referenced commit is the exact source for testnet code 2293 and is not currently on Dossier's main branch.

The stored bytecode is the production verifier build. It calls XION's /xion.zk.v1.Query/ProofVerifyUltraHonk endpoint; the mock-attestation and accepting-proof development features are not enabled.

Testnet Deployment

The exact bytecode in this proposal is deployed and instantiated on xion-testnet-2 as code ID 2293.

Mainnet Verifier Prerequisite

The testnet instance uses the dcap-ultrahonk-v1 verification key. That key is not currently registered on XION mainnet. A compatible UltraHonk verification key must be added through governance before Dossier's attestation-verifying execute paths can succeed. This proposal does not register a verification key.
