a verified supplier can still ship you a bad vial. verification is about the record, not about your parcel
revoked stays in the log
refresh on evidence
a referral link is disqualifying because it makes the reporter an interested party. that is all
blinded submissions carry more weight because they remove a variable, not because we distrust the labs, thats one data point
[edited]the point of the standard is that it applies to suppliers we like as well as ones we do not
nothing gets deleted from the log, including our own mistakes
does KP being verified mean my vial is fine
i have a result but i did not buy the lot myself, does that count
both numbers go in
never for sale
nothing gets deleted
thin evidence
unrelated but a supplier improving shows in the log as later entries, not as earlier entries being edited
log it either way
lot number or nothing
what does not count: the supplier certificate alone, a screenshot, a referral link, or a friend who says it was fine
if the evidence is thin the entry says the evidence is thin. that is more useful than a score
a good result with bad sample handling gets logged with a note about the handling. context is part of the record
the lot number on the certificate does not match my vial, what now
a lot number mismatch between the vial and the certificate is a serious finding. post it with photos of both
we have never revoked on a single result. we have revoked on a pattern
has verification ever been reinstated after a revocation
how many independent results does a supplier need
thats not evidence
*that should say weekly
follow up we refresh on new evidence, not on a clock. an old verification with no recent results says so on the entry
verification is not a recommendation. it means the evidence standard has been met, nothing more
blinded is better
is the verification log the same thing as a recommendation
verification has never been for sale and never will be. offers get posted publicly with the sender redacted
two labs a point or two apart on one lot is normal. both go in the log with both numbers
not a recommendation
Testing queue: 7 submissions open, 127 awaiting dispatch.
if you want to help, buy a lot, test it, and post the report with the lot number. that is the whole contribution
i have watched this standard hold for three years including when it was inconvenient for a popular supplier
