Count exact units
Unit amounts and total supply follow exact rules. A display percentage is a presentation of that ratio. Transfers and supported issuance must preserve supply and prevent the same units from being assigned twice; rounding in a screen cannot authorize additional ownership.
Connect to custody
For a physical item, the asset receipt and custodian establish the backing relationship. For a digital claim, inspect its corresponding rights and original. Share supply, backing and owner transitions need to remain linked rather than becoming unrelated labels.
Review supported execution
A share definition alone does not guarantee that purchase, division or redemption is executable in every deployment. The available action must identify its admitted contract, current proof and authorization. Do not infer a live market from the existence of a share count.
Inspect the result
Keep the source that records the actual share position and any related payment. A valuation of the whole is different from the executable price of a share. Liquidity, proceeds and redemption availability require their own evidence.
Method, sources and assessment
This explanation describes the supported implementation. Exact protocol requirements come from the pinned Receiz contracts and original sources. A reference result does not qualify a production deployment or a physical device.
