Three new ribs, slid into three of the opened sockets on the cold side, taking load off the bowing struts beside them. Spreading the lattice’s load across the cage instead of letting it pile onto the bow.
“Three composite ribs,” he said. On the link. “In three sockets. Spaced around the bow.” He read the positions. “They can spread the lattice load. Long enough for the returns to stabilize. Hearth’s, Lorn’s, Tal’s at half. Long enough for the outer ring’s return to be lined and opened. I’ve worked it twice. With the three real sensors and the four guessed ones.
