A passport data field is easier to review when it points back to a stable source URL. Lithium Record gives those source files a durable public record and hash. 1
This spoke belongs to the Battery Passport Lithium Vault pillar at /battery-passport-lithium-vault/.
URL as evidence pointer
A source URL should identify the file behind a passport-supporting data point. For lithium, that file may support carbon footprint, origin, material identity, recycled content, or due diligence. The page should name the file and state what it supports. It should not imply the URL itself is a regulated passport entry.
Integrity and access
A verifier can use the URL and hash to check whether the displayed file matches the recorded evidence. Access policy still belongs to the passport operator or customer. Lithium Record provides the evidence pointer and file-integrity reference, not the full regulated access-control system.
Linking pattern
Every source URL page should link up to the Battery Passport vault pillar and sideways to data-field mapping, verifier access, and retention pages. If the file supports carbon or provenance, it should also link to the relevant pillar so the reviewer can inspect the broader record chain.
