/*
 * WHICH FRESH GIGS EARN A MODEL CALL.
 *
 * The owner's complaint, exactly: "i see fresh gigs in the watcher while I dont have a draft".
 * Drafting only ever happened when something called the draft route, and nothing did, so the watcher
 * filled with ranked gigs and no words. On this board a gig collects five offers in fourteen minutes
 * and ninety in six days, so arriving late is the same as not arriving.
 *
 * But drafting EVERYTHING is the opposite mistake: a draft is a model call, and the standing rule is
 * tokens only on money-moments. A six-day-old gig with ninety offers is not one.
 *
 * The fixture below is the real useme-gigs feed as it stood when this was written, scores, ages,
 * offer counts and all. Both failure modes it guards against are silent: spending on the gigs least
 * likely to answer, or quietly drafting nothing.
