The buried body’s hand stayed open under the stone.
The old body in the case kept one finger pressed to the glass.
Between them, the board held Daemon’s cut like a bad answer someone had tried to cross out with force.
Ty looked at the three marks again and read them by position. Stone trough first, case track second, and Daemon’s cut across both.
The order made his sore hand ache because the receiver tooth under it had already tried to choose. The machine wanted the case body to count as the kill. The board said the stone body belonged to the anchor. Daemon had cut through the route before either could become clean.
"The wrong kill is not a metaphor in this room," Blue said.
JJ kept her shoulder against the case frame.
"I had almost gathered that from the bodies arguing through furniture," she said.
Blue ignored the edge in her voice and pointed at the groove.
"The receiver has two positions and one kill feed," she said. "It fed the case body through the place where the anchor should have stayed quiet."
Rusuf’s sword hand shook again under the lip.
"If the receiver corrects itself, what does it take?" he asked.
Blue looked at the case, then at the open hand under stone.
"It takes the cleanest available kill from the position it thinks owes one," she said.
Yun-Jin’s fingers tightened around the service pin.
"That means the body under stone pays for the case body," she said.
"Or the case body pays again if the receiver likes repeats," Ty said. "This place has shown enough appetite for that."
The old body in the case pressed harder against the glass, and the buried body’s open hand flexed once beneath the stone.
JJ swore under her breath without making the word loud enough for the room.
"I am open to a plan where nothing gets killed twice," she said.
"The plan starts by keeping the board from correcting," Blue said.
The board’s groove widened another hair as if it had heard the word correcting.
Ty saw the line under Daemon’s cut deepen. It ran from the case-track depression toward the stone-trough depression, trying to complete the path Daemon had broken.
Yun-Jin lowered her face closer to the board.
"He cut across both marks because choosing either body finished the route," she said.
"Then Daemon’s answer was to leave the mistake unfinished," Rusuf said.
"Unfinished is ugly, but ugly keeps people alive here."
Ty looked at the cracked ceramic fuse still lying in the tray.
The fuse had been broken by hand and placed where a worker would check first. Blue had called it chosen dead. Ty understood the phrase better now. Daemon had left a dead thing to stop a dead thing from being used.
"The fuse belongs in Daemon’s cut, because he placed it where a worker would check," Ty said.
Blue looked at him, then at the groove.
"A dead fuse across the cut would block the correction path without feeding either side, and it will also make the receiver angry," she said.
"The receiver can join the hallway’s long complaint line," JJ said.
Rusuf adjusted his grip on the maintenance sword.
"I can hold the lip through one more step," he said. "After that, the blade may start acting like honest metal."
Yun-Jin lifted the service pin slightly while watching the groove.
"If I turn the pin back, the board releases," she said.
"Keep it where it is until the board accepts the block," Ty said. "We need the board awake enough to recognize the wrong path."
"That sentence sounds like feeding a trap on purpose."
"It is feeding the trap a broken tooth."
JJ glanced at him, then back at the board.
"That image is disgusting enough to be useful."
Blue picked up the cracked fuse with the strip of gray cloth. She avoided the darkened ends and held it above the groove. The board pulled at it faintly, not with magnetism, more like a drawer sliding toward a familiar handle.
Ty kept his fingers on the copper line through the cloth, and the hook contact trembled against him.
"Hook is moving toward the wrist ring again," he said.
Yun-Jin shifted her free hand under the loose hook without touching bare metal.
"I have the hook blocked from below with the cloth edge," she said.
Blue placed the cracked fuse across Daemon’s cut, and the board snapped shut around it.
The sound ran through the receiver, through the case frame, through the stone lip, and into Rusuf’s sword. His jaw tightened as the blade took the pressure.
The old body in the case struck the glass with one finger.
The buried body’s open hand curled halfway shut.
The fuse held across the cut, and for three breaths, nothing fed through either body.
Ty counted all three because his body wanted to move before the room finished answering.
On the fourth breath, the board started grinding under the fuse.
"It is trying to chew through the dead fuse," Blue said.
"Can it chew through the fuse before we move?" JJ asked.
"Given time, machinery defeats most insults people place inside it."
Ty looked at the seven marks on the film. The angled mark beneath the seventh sat where Daemon’s cut crossed the bodies. It matched the fuse now, not perfectly, but close enough that Ty saw the intent.
"The fuse is only the stop, and Daemon left the film so we could set the direction after the stop," he said.
Yun-Jin read the film over his shoulder.
"The angled mark points away from both bodies," she said.
"Toward what part of the tray did he point us?" Rusuf asked.
Blue turned the film above the board until the seventh mark lined with the service pin. The angled line pointed toward the tray’s back edge, under a strip of metal Ty had dismissed as trim.
JJ followed the angle and made a face.
"Of course the answer is under the piece nobody wanted to touch," she said.
The board ground harder against the fuse, and Rusuf’s sword slipped by a fraction under the lip.
The stone lip dropped and stopped against the blade again. Dust fell over the buried body’s wrist. Yun-Jin kept the hook away from the ring with the cloth-wrapped edge of her hand.
Ty moved to the tray’s back edge without crossing the hook line.
"Blue, keep the fuse seated while Rusuf calls out if the lip shifts again," he said.
"If the lip shifts again, my wrist will announce it before I do," Rusuf said.
Ty pressed the tray’s back strip with two fingers, and it sank under pressure.
A small panel slid open, revealing two curved metal pieces nested beneath the board. They were thin, hooked, and set opposite each other like harvesting blades that had forgotten the field. Each one had a tiny contact tooth pointed toward the board’s center groove.
JJ leaned just enough to see without easing off the case.
"Please tell me those are decorative workplace hazards," she said.
"Those are listening hooks set under the correction path," Blue said.
"That name improved nothing for anyone currently breathing."
"They listen for a correction path before cutting it away," Blue said. "If the board tries to feed a kill, the hooks cut the path and carry the signal somewhere else."
Ty looked at Daemon’s cut, then at the curved hooks.
"Sickles, because Daemon never named a tool kindly," Yun-Jin said.
The word landed harder from her than it would have from anyone else.
Rusuf stared at the two curved pieces under the board.
"Daemon used sickle relays in old field shelters," he said. "They cut power away from a wounded line before fire could spread."
Blue kept the fuse pinned with the cloth.
"These are smaller, but the idea fits because they need to hear the wrong path before they cut it," she said.
The board ground against the fuse again. The left hook trembled, and the right hook followed.
The case body pressed its finger to the glass.
The buried body under stone held its hand half closed.
Ty kept his fingers above the tray strip and watched both hooks turn toward Daemon’s cut.
"Let them hear only the wrong kill and nothing else," he said.
Yun-Jin kept the hook contact blocked while JJ held the case in place and Rusuf held the lip.
Blue held the dead fuse across the cut.
Under the board, the two sickles opened toward Daemon’s cut.
