The engine cases as fetched pages, exactly the Pages model: every case is a triple in a
group directory of apps/regression/framework/ - the .pad its template,
the .txt the outcome beside it, an optional .php its variables -
and each is fetched directly as the page it is. A request per case grants each one its
isolation by construction; the price is nine hundred requests a run, which is why Test
runs and a page load only reads.
