This URL does not move. The living stamp is /now/. Absence in a later snapshot is not rewritten here.

Priced for the balanced mix: three parts input to one part output, no cache assumed. Changing the mix is a different question; this page is a stamp, not a slider.

This stamp is kept as published. The board has changed since: correction §83 and correction §96, and the data refresh of 2026-10-06 18:04 UTC. The living stamp at /now/ carries the changes. Read correction §83Read correction §96

A staircase, not a curve. Between two rungs there is no model, so a smooth line would invent options that do not exist. Chartreuse marks the undominated set. Each graphite dot has a model that scores at least as high, costs no more, and wins on one of the two. Logos name the vendor; they are not a ranking colour.
