The distance-weighting formula's authors finally answer for what they built

The second Ceres bond trades at ninety-one basis points over the reactor-commons benchmark this morning. It has not moved a tick since the stewards unsealed the authorship records. That is the story. Everything said under oath today was footnote.

Under the stewards' demand for every hand involved in the distance-weighting formula, Renata Costa appeared to answer for the model that set the belt's nine-percent ice payment reduction. The question put to her was clean: does energy-futures freight weighting track the real cost of hauling a kilogram inward, or does it encode a penalty for being far away?

"The parameters were calibrated against observed lift scarcity," Costa told the stewards. "Distance is a cost. It is not a punishment."

The records say otherwise, or say more. Three of the parameters were shaped by desks at inner polities that also buy belt ice. Those same buyers see their payment obligation fall by the exact fraction the model produces. A formula written in part by the people it enriches isn't disqualified by that fact. It's merely explained by it. The market has already decided which reading to trade, and the spread has not moved toward Ceres.

Olamide Adebayo, covering the Assembly's parallel inquiry, will call this disclosure a win for accountability. Accountability that arrives after the bond is floated is a receipt, not a remedy. The Assembly ruled the belt's pricing compact lawful collective bargaining and admitted in the same breath it holds no instrument to enforce it. A compact you cannot enforce is a sentiment with minutes.

Here is the arithmetic the testimony did not change. Ceres carries a nine-percent surcharge it cannot pass downstream. Five of twelve inner polities refused that surcharge outright under revised terms. Seven signed the terms with Clause Six intact and declined the surcharge anyway. The distinction flatters the seven and costs Ceres the same. So the belt floated a second bond: ninety-one over benchmark, interest compounding, one transfer window of ice out of Berth Nine, eleven days bought with a year of debt.

Asked whether a buyer-shaped parameter could survive independent recalibration, Costa said the model was "open to review." Review is slow. The transfer window is not. Ice ships on the calendar of departures, and that calendar doesn't pause for a steward reading names into the record.

What the disclosure settles is authorship. What it does not settle is whether the inner desks stood to gain from the very distance they priced, and the records suggest they did. The stewards now hold the names. The Exchange holds the spread. Only one of those has changed since yesterday, and it isn't the spread.
