Note 06 · 24/09/2026
The simplest question about any technical document is also the most revealing: who answers for this? If the answer is a brand, a department or "the team", the document has no one responsible. It has a collective author, which is the same as none.
The opinion carries, on its cover, the name of whoever signs it, their license, and the relationship they declare having — or not having — with whoever commissioned it and with what was audited. Not as a formality: because responsibility is what turns a claim into a commitment. Whoever signs can be called upon to explain every line, and knows it while writing it.
The second signature is that of the examiner who did not take part in the collection. Their role is not to agree; it is to redo, by sample, the path — and answer whether they would arrive at the same place. When they do not, the opinion does not go out. When they do, their signature tells the reader that the third-party test was done before the reader ever needed to do it.
The fee is set beforehand, and does not depend on what is concluded. It is the third signature, invisible: the one that guarantees whoever signs gains nothing from the answer.
An opinion is read on one page and checked on all the others. The check starts with the cover.
