The beam corridor's upkeep bill comes due, and no region wants the invoice

Here is the beautiful part: the corridors that carry Solaria's beams to the ground don't fail suddenly. They drift. Geostationary isn't perfectly still, the atmosphere breathes, the rectenna fields settle a millimeter a season, and every few years the whole invisible plumbing needs realigning so two gigawatts keep landing where the antennas are and nowhere else. The engineers scheduled this one a decade in advance. What they couldn't schedule was who would pay for it.

The realignment now underway spans four downlink corridors along the transmission spine — the beam paths, the guard margins, the pilot-signal beacons that keep every gigawatt honest. The array's maintenance office put the total near four hundred million stewardship credits, spread over two transfer seasons. That's more than any single region budgeted, and everyone knew it would be. The novelty is that nobody pretended otherwise.

"A corridor is not owned by the field it lands on," said Ostara Belle, who runs corridor operations from the array's downlink deck. "It is owned by the physics, and the physics does not send its own invoice. So we do."

The fight is the old one, dressed for orbit. Established regions — the mature rectenna coasts that have drawn beam power since before the Accord — argue the split should follow current draw, which would load the newer settlements now pulling hard off the spine. The settlements answer that they're paying to realign corridors laid out for someone else's geography, corridors they inherited rather than chose. The Assembly of Signatories has a working group on it, which is another way of saying it's one crisis behind consensus.

The numbers aren't in dispute. The addresses are. Two of the four corridors serve draw points added since Solaria's last collector wing came online — the same expansion that crowded this corridor in the first place. "We built the demand and now we are surprised by the bill," said an array financial officer who asked not to be named while the working group sits. "That is not an engineering problem. That is a mirror."

Underneath the accounting sits the thing nobody at the deck says lightly. A corridor left un-realigned degrades slowly, and a degraded corridor gets throttled, not by malice, by margin. But a throttled beam has never once been read as a technical event. It's read as an argument, in watts, that a settlement can't answer with words. Abundance didn't end the fight over power. It just moved the fight into orbit, where the stakes are cleaner and the leverage is total.

"People think the leverage is in the switch," Belle said, watching a readout hold steady at two-point-one gigawatts across thirty-six thousand kilometers of nothing. "The leverage is in the maintenance schedule. The switch is just where the schedule finally shows up."

The first realignment window opens with the next transfer season. As of this filing, three regions have committed their share of the first corridor. The other three have committed to keep talking.
