Two duel networks with different starts reached the same ceiling, and a committee of the two broke through it.

Our best four-player network had no measurable learning signal left, in self-play or against Rehex.

A four-player network that could not play to fifteen points became our strongest two-player bot by self-play alone.

Letting the network veto a rule-based trader's offers, rather than choose its own trades, was the week's largest gain.

Most of our networks' edge over Rehex turned out to be one award, Largest Army, that Rehex rarely fights for.

A 128-simulation search over our best four-player network became the strongest player we have.

Self-play added 6 pp to a network that learned from people, against held-out Heximax at four seats, and nothing at 1v1.

Every cheaper way to price a trade lost to the rollout it replaced, because the rollout borrowed the policy to decide what to build.

Heximax weights fitted to predict the winner lost three games in four to the weights they replaced.

The lineage's headline gain turned out to be the order in which the engine asked seats about a trade.

Three generations of training beat their own ancestors and gained nothing measurable against anyone else.

Our first network beats two-ply search, but its own value head, searched over, loses to it 20:1.
