Overview
Every routing decision this proxy made for your tenant, and what it cost against always calling the top rung.
Experiments
A route with a [route.challenger] tests a cheaper model against your current one: in live mode a random share of sessions is served by it and you report task outcomes; in paired mode it re-runs sampled requests off-path and your gates grade both answers. Firstpass never switches models on its own: it stops sending traffic to a challenger that is proven worse, and shows you the change to make when one is proven good enough.
Receipts
Newest first. Select a receipt for every attempt, gate verdict, cost, latency and its place in the hash chain.
