Independent reliability evidence

Method

How this works

Every check we run explains itself, including what it cannot show.

Two records, two kinds of evidence

The MeterThe Ledger
What it isWe ask the same fixed questions every day and write down what comes back.A company published a change, or we measured one. We write down what happened and keep the evidence.
Whose evidenceOurs. Our own runs.Theirs or ours. Every entry says which. Today they all say theirs.
What it cannot tell youWhether a change was deliberate, or how one company compares with another.Whether anything changed that nobody announced and we have not measured yet.
How the Meter measuresWhat we seal before we look, why some checks are not public yet, and what we can prove we sent. How the Ledger worksHow a change is found, what evidence an entry needs before it is published, and how a correction is made.
