The four lane codes

Every row is filed under one of four codes, and the codes are the whole taxonomy: P for the prescription lane, where a prescriber and a licensed pharmacy stand at the gate; R for the research supply lane, where a per-batch analytical record stands in place of a gate; N for a returned result that sells nothing along either lane; and U for a domain that cannot yet be placed. A row carries exactly one code, and a code names the lane and nothing more.

The live-read requirement that governs every cell

A code, and every cell beside it, is written only from a page opened during the build and then stamped with the date it was read. Nothing is filled from a search snippet, a directory listing, an outside review, or the shape of a domain name, because each of those describes something other than the seller's own current page. Where no page was opened, the cell reads not established, page not read, and that value ships as a real answer rather than a guess, which is why the table can be honest and mostly empty at the same time.

What a failed fetch produces

A fetch that returns an error produces one output and only one: the note that the fetch failed, stamped with its date. An error describes the tooling and not the page behind it, so a failed read is never turned into a claim in either direction, and the four domains whose only attempted fetch failed this run carry fetch returned an error across their cells rather than a filled lane. A page that could not be read is left unlinked and unquoted until a later read succeeds.

The sort order, and what disqualifies a row

Rows sort by lane first, prescription then research supply then not-a-route then unclassified, and by search position second, with both steps mechanical and unpaid. A row is disqualified from a filled lane by a single thing, the absence of a stamped live read, and a domain that pays a commission gains no position and loses none. Who pays for what is stated plainly at who pays for what, and the table this method produced is on the flagship, the table this method produced.

Scope and research use

This file reports two things and no third: the lane a route belongs to, and the paperwork that route can produce. Material named anywhere in the research supply lane is laboratory stock rather than a licensed medicine, and the supplier cited on this site states on its own pages that what it sells is research-grade and not a medicine any regulator has signed off. Nothing here weighs up a person or calls anything safe or effective, and a question about a person belongs with a licensed clinician.
