A beam corridor's upkeep bill finds no willing payer

Here is the beautiful part, and I never tire of it: a beam corridor is an act of pointing. Solaria's collectors gather sunlight thirty-six thousand kilometers up and hand it down as a microwave column, and the trick is that the column has to arrive where the antennas are and nowhere else. The corridor over Sonora Flats holds its aim to within a tenth of a degree. The crews quote that number like scripture and treat the second decimal place as a moral question. Air moves. Ionosphere shifts. The beam gets corrected against all of it, continuously, by hardware that someone climbs to and inspects on a fixed cadence.

That cadence has slipped. The corridor's mid-altitude alignment array was due for its scheduled inspection two windows ago. It hasn't happened. Not because a treaty power reached for a knob — nobody throttled anything — but because the inspection costs watts and money to mount, and no one at the table has agreed to carry the line item.

The table is the corridor's cost-share pool: three established regions that host the rectenna acreage and draw the delivered power, and two settlements — a Lunar District co-op and a Verne Station manufacturing consortium — that buy corridor capacity forward on the Orbital Exchange. The established regions say the settlements' bought capacity should carry a proportional slice of upkeep. The settlements say they pay for delivered watts, not for the ladder someone climbs to keep the aim honest.

"An inspection deferred is not a failure. It is a debt," said Amara Osei, who supervises alignment maintenance for the Sonora corridor and has done the climb herself. "The array is holding tolerance today. It will hold tolerance next window. I cannot tell you it holds the window after that, and I refuse to guess in public."

The numbers are small enough to be embarrassing. The disputed inspection cycle runs to a figure the corridor clears in delivered energy inside an afternoon. Here is the ugly part: small bills are the hardest to assign, because everyone can afford them and no one wants to set the precedent. Whoever pays this cycle pays the next one too.

The Accord's cost-share framework was written for corridors owned outright by a single region. Shared corridors are the norm now, as settlements buy in, and they fall into a seam the Assembly of Signatories has flagged twice and legislated for never.

Osei's crew filed the deferral through channels and logged the array's current drift readings, which remain inside spec. She keeps the log open on her console at the field office.

"Two gigawatts, landing like rain," she said, tapping the readout. "The rain doesn't care who owns the ladder. The ladder does."
