Rook opened the control route with the caretaker’s instruction still displayed above his hand.
For a breath nothing visible changed. Then the chamber filled with information too quickly for the staff to mistake it for an ordinary status refresh. District barriers unfolded in separate layers. Load moved along lines that had previously carried only approximate totals. A damaged frontage appeared with its latest repair beside the older survey, the difference marked clearly enough that a technician called for the street crew’s independent result.
“Compare before acting,” Rook said.
The first value matched. The second needed a reference correction, then matched within the street instrument’s tolerance. A third showed a change the district had reported two minutes earlier and the chamber’s ordinary relay had not yet entered. The liaison who had argued for the project put both hands on the back of a chair and laughed in relief.
“That is what they promised,” he said.
The technician at the independent sensors did not laugh. She asked for another district. They checked it. Again, a useful match.
Rook looked around the room. These were not imaginary benefits offered to excuse a speculative mechanism. They were current defenses, known repairs, people whose positions they could now see before a messenger returned exhausted. He asked which failing line had the nearest crew and received the answer before the ordinary duty board had finished finding the right column.
