That reads as a recommendation and the source pages deliberately are not. They are a record you use to make your own decision.

a claim with no batch number is a marketing document

Moderation of individual cases happens in modmail rather than in threads, because a public discussion of one person’s removal is worse for that person than a private one.

What breaks if we make that change?

Did you ask for the batch-specific certificate, or the generic one?

The order I actually check things in, for anyone building a process rather than asking about one supplier.

This is the whole method in one sentence. Everything else in the thread is elaboration.

Cosigning on lot matching. It sounds trivial and it predicts almost everything else about how an operation is run.

What did they say when you asked for the method line?

Disagree that reviews are worthless. They are worthless when they say "fast shipping A+++". A dated one naming a compound and a document is evidence.

Asked GL Biochem for the batch record on a Tuesday and had the full document, batch and method line, before the end of the day. That is the bar now.

Proposed a rule change here with actual wording and it was adopted. That is the process working and it is not fast.

Which lane, and what was the quoted lead time at checkout?

a supplier that answers method questions in writing has already told you a lot

Yes — a proposal with concrete wording gets discussed. A complaint about the rules in general does not.

Yes. Spread across lots is the number that tells you about the process. A single high result tells you about a vial.

the source page log is more useful than the score above it

Complained about a rule without proposing anything and was politely pointed at this page. Fair.

a directory entry is a record, not a recommendation

Why the directory has two tiers, since the question comes up whenever somebody new finds it.

search_before_post is describing the batch record test and it is the fastest signal available before you spend anything.

Agreed that the top comment is not the best answer. The ranking optimises for early agreement.

the wider-market names in the table are there because nobody has enough data on them

Would qualify this slightly. Fewer entries means less sampling, and less sampling is not the same as a worse process.

Mild pushback: a supplier with fewer entries is not worse, it is less sampled. Those are different claims and the table says so.

a rule you cannot inspect is just a preference

This. Ask for the batch record. The ones who send it inside a day have told you more than any review could.
