What a vault entry contains
A vault entry contains producer identity, mine or brine source, product type, extraction method, processing route, carbon footprint, water context, verifier status, and a SHA-256 evidence hash.
Tier 2-4 // LITHIUM RECORD
The Lithium Record Vault
Vault landing page explaining record contents, OEM-facing verification URLs, sample records, verifier handoff, and hash-chain logic.
Evidence architecture
Structured for producers, verifiers, OEMs, and machines
What OEM customers see
An OEM customer sees a clean verification page with the record summary, material details, verification status, supporting document references, and schema markup for machine readability.
Worker boundary
This static page explains the vault. Live /vault/lr_* records are intended to be rendered by the later Cloudflare Worker layer.

Core fields in the record layer
Every page in this static layer points back to the same operating premise: lithium compliance evidence needs a stable, readable, citation-friendly URL rather than a disposable file export.
| Record field | Why it matters |
|---|---|
| kgCO₂/kg LCE | Translates site evidence into OEM carbon-footprint workflows. |
| GPS and extraction route | Hardens provenance and supports due-diligence review. |
| Verifier signature | Shows independent assurance status and review trail. |
| SHA-256 hash | Connects documents, metadata, and permanent record identity. |
