For certifiers and auditors: read the records, not a folder of files.
Sign the certificates you issue, withdraw them when you must, read the evidence of the lots a company gives you access to, and verify a signed report without an account.

What you record
The certificates you issue
Uploaded for the lots that concern you. A certificate signed by its issuer carries the highest evidence level.
Withdrawals
Only the issuer withdraws a certificate. A company that disagrees marks it disputed, with a reason and the evidence, and you are told; it still counts until you withdraw it.
Lab results
On the lot they describe, with the lab that issued them.
What you approve
Nothing in the company's records
With verifier access you read; you never change a company's records. The company's people approve every change.
The access you are given
Chosen lots for at most one year, created by the company's owner with a second factor, with every read logged.
Reading by software
With the credential you receive, your software or AI agent reads through the API or the MCP server, and sees only the lots and the evidence the access covers.
Whether you are trusted
Each company chooses the issuers it trusts for each type. A certificate from an issuer it no longer trusts says so.
What you prove
What is signed and what is only declared
Every certificate shows its evidence level: declared by the company, recorded for a party, or signed by the party itself.
The certification audit pack
Certificate validity and certified volume reconciliation, signed.
Any report, checked without an account
The verification page checks a signed copy. It does not need an account or trust in A-REX.
Your place in the chain
Each company records its own link. The lineage joins them, and each side chooses what it shares, item by item.
