3.L1 — real purchases

Get one email when this record's verdict changes. No digest, no marketing — one message per change, and only for this endpoint. We first send one confirmation email; nothing else goes out until you confirm.

4.Catalog listing events

No listing changes observed.

unverified is not a failure; a fail is published only after two consecutive failing probes. Definitions: methodology.

5.Dispute this record

A dispute does not start a purchase. The signed dispute route runs one fresh L0 check, an unpaid request.

Think a measurement above is wrong? Say which probe or purchase and what you observed instead. One person reads it and replies. The record is never deleted on dispute: if it was wrong, the correction is published with the same weight. If it was right, it stands. A dispute filed on the record form puts an active listing on a priority list. L0 runs probe that list before their ordinary queue, one run at a time. A listing whose URL has an unfilled path parameter is not put on that list. One run measures up to 50 priority listings, at most 5 from one site. Published fails whose catalog declaration changed, or that rest on probes recorded under earlier rules, take places first, and disputes fill the places left. A listing probed in the past 60 minutes waits for a later run. A dispute that no run reaches within 7 days leaves the list. The scheduled L0 run is at 10:30 UTC, and an L0 run at another time can measure the listing first. The record stays on this page. When a run measures the listing, the new probe is added to its history. Send the dispute to support@vet402.com. Published corrections are listed at /corrections. Operators who control the receiving address can also sign a dispute via POST /api/v1/observatory/disputes (API reference). That route runs one fresh L0 check under the normal publication gate. A later purchase comes from the regular schedule.
