Ownership & Collateral Record
Note: For this proof-of-concept (PoC), information normally accessible only to licensed/authorized businesses (the parties’ real names and deal terms, serial numbers, original photos before masking, photo hashes, etc.) is shown here specifically to illustrate how the model works. Normally, AURAM manages data in two layers: a public ledger that anyone can verify on-chain, and a permissioned registry that keeps sensitive data confidential. The integrity of this confidential data is committed on-chain as the identification hash, so anyone can independently verify it against the on-chain values by following the Third-Party Verification Guide (in production, this data is subject to access control).
1. Identification
Information that uniquely identifies this gold ingot. The identificationHash computed from 5 elements (manufacturer, serial, weight stamp, purity, photo hash) is committed on-chain.

2. Ownership history
Ownership transfer is recorded in two stages: declaration of intent (cause) and transfer of possession (perfection). The declaration of intent is what causes the transfer, such as a sale (Article 176), whose terms hash (termsHash) is published on-chain. The transfer of possession is the subsequent stage (Article 184 / Article 178 perfection).

Declaration of Intent (Cause)
Article 176 (will principle): ownership transfer takes effect by the parties' declaration of intent. The cause is published on-chain via termsHash.
Transfer of Possession (Perfection)
Article 184: instruction → consent completes the transfer of possession (consent is the perfection point); Article 178 perfection is satisfied.
3. Collateral history
Pledge / release of transfer-collateral is recorded in two stages: declaration of intent (set / release) and transfer of possession (perfection). It is transferred to / from the secured party via the transfer of possession (Article 184).
Declaration of Intent (Set / Release)
Article 176 (will principle): the pledge/release of transfer-collateral takes effect by the parties' declaration of intent. The cause is published on-chain via termsHash.

Raw data: full list of all Tx for this NFT (pre-annotation chain raw data)
All on-chain operations (Tx) against the AssetNFT contract. If the side-by-side annotation above is the post-annotation view, this is the pre-annotation raw data. Because Snowtrace's individual NFT page only shows ERC-721 Transfer events (mint and ownership transfers), all Tx including state changes such as setStatus can be checked from this list.
