Highlights from this day
- power_cut_pia — follow up verification is revoked on a confirmed failure and the revocation stays in the log permanently 20:59
- karl_fischer — coming back after 24 months, has the standard changed 21:16
- ollie_orders — we refresh on new evidence, not on a clock. an old verification with no recent results says so on the entry 21:47
somebody once offered to fund the testing programme in exchange for an entry. the offer is in the log, we shall see
follow up verification is revoked on a confirmed failure and the revocation stays in the log permanently

a supplier improving shows in the log as later entries, not as earlier entries being edited
a lot number mismatch between the vial and the certificate is a serious finding. post it with photos of both

verification has never been for sale and never will be. offers get posted publicly with the sender redacted
thats evidence
thats not evidence

coming back after 24 months, has the standard changed

if the evidence is thin the entry says the evidence is thin. that is more useful than a score
is the verification log the same thing as a recommendation
has anyone ever offered to pay for verification
we have never revoked on a single result. we have revoked on a pattern
what does not count: the supplier certificate alone, a screenshot, a referral link, or a friend who says it was fine

| Evidence | Counts? |
|---|---|
| Independent report, lot you bought, lot number legible | yes |
| Independent report, no lot number | no |
| Supplier certificate only | no |
| Screenshot of a report | no |
| Blinded pooled submission | yes, for the pool |
| A friend who said it was fine | no |
log it either way
does Homopeptide being verified mean my vial is fine
two labs a point or two apart on one lot is normal. both go in the log with both numbers
does a good result from PeptideMeter outweigh a bad one from Janoshik

lot number or nothing

update from 13 months ago: QST added evidence and the entry now reflects it
[edited]a good result with bad sample handling gets logged with a note about the handling. context is part of the record
two labs disagree on the same lot, which one goes in the log
why is a referral link disqualifying rather than just ignored
i have a result but i did not buy the lot myself, does that count
gradient_gregwhat does not count: the supplier certificate alone, a screenshot, a referral link, or…
has verification ever been reinstated after a revocation
blinded submissions carry more weight because they remove a variable, not because we distrust the labs, i think
the lot number on the certificate does not match my vial, what now

a verified supplier can still ship you a bad vial. verification is about the record, not about your parcel
if you want to help, buy a lot, test it, and post the report with the lot number. that is the whole contribution
thin evidence
post the photos
