On the first full day of the training hold, the exoskeleton closed around Leo one piece at a time.
The black support frame settled against his back and legs. Its dull silver-gray armor plates had been folded back so Gauss could reach the contacts along Leo's spine. The suit was open enough to leave him feeling exposed and closed enough to make stepping away impossible without help.
Gauss tightened the left calf brace, checked it with two fingers and moved to the right.
“Keep your knees loose when the frame wakes.”
“That sounds like advice learned the hard way.”
“Early frames stood up before their wearers were ready.”
Leo looked down at the sealed helmet above Gauss's shoulders. “You saw that happen?”
“Often enough to start every fitting with the warning.”
Gauss's hand had already found the next adjustment catch without looking.
Gauss clipped the suit's short retention tether to a floor anchor in the test bay. The field-service lock remained beyond the far line, closed beneath TRAINING HOLD. The timer beside it marked the first of two full preparation days.
“Do not help the frame,” Gauss said. “Take one step when the line turns green. Stop when it turns red.”
“Walking. I was hoping we'd begin with something advanced.”
“Standing is the advanced part.”
The contacts along Leo's back cooled. Blue light moved through the collector lines at his sides, and the weight of the frame vanished without actually leaving him. It was still there around his body. He could feel every joint waiting.
The line on the floor turned green.
Leo stepped.
The frame drove the step farther than he intended. Leo's strengthened legs corrected at once, pulling him back, but the delayed assistance followed the correction and shoved him forward again. For one ugly second, his hips turned one way and the armor chose another.
Gauss struck the cutoff on his wrist. Assistance vanished. The suit became weight, but it stopped arguing. Leo caught himself before the tether tightened.
Silence returned with the blood beating in his ears.
“I thought you said not to help it.”
“You moved faster than its standard profile.”
“So it thought I was weaker than I am.”
“It thought you were ordinary.”
That should not have bothered him. The machine had been built for bodies that had not rewritten themselves. Still, ordinary had once been the entire plan.
Gauss opened the calibration record. A pale outline of Leo appeared on the wall display. What Leo had felt as one bad step separated into his movement and the frame's late response. His pulse climbed beside them. The tremor in his left hand appeared as a thin irregular band.
Agreeing to the sensors had been easier than watching his fear become a line on Gauss's wall. Leo drew the hand closer to his side. The trace had already kept it.
“Do I get a copy of this?” Leo asked.
“Of every training and field archive.”
The tremor line continued beyond the point where Leo remembered his hand going still. “Good,” he said. “If the suit catches something I miss, I want it in my copy.”
“It will be there.”
“And if it tries to help before I ask?”
“Then we teach it to wait.”
Gauss released the catches across Leo's chest. “We can stop the fitting.”
The open frame behind him suddenly seemed inviting. The machine had moved his body after he had chosen otherwise, a small theft of control and exactly the kind of thing Meridian had taught him to fear. But Gauss had cut the assistance before the tether caught him, then shown him precisely what had happened.
“No,” Leo said. “Turn it down and let me try again.”
Gauss closed the catches without argument.
While Gauss adjusted the frame, Leo kept his eyes on the red floor line. One step. One stop. His pulse had not settled, but he did not need it to settle. He needed the machinery to wait for him.
Gauss lowered the assistance curve and adjusted the hip response by hand. He did not consult a manual. His gloves moved from one catch to the next with the ease of someone who had repeated the same corrections while other people tried not to fall.
On the second attempt, the suit waited.
Leo crossed the green line, stopped at red, turned and came back. The frame followed instead of leading. When he crouched, its joints took part of the load without forcing his knees farther than he intended. He rose so easily that his muscles prepared for the effort after he was already standing.
Gauss handed him the empty rifle case from the previous night.
Leo lifted it, changed direction and set it on the marked stand. The case had almost no weight. The frame still recorded how his fingers tightened before the lift and how his right foot shifted to prepare for a burden that was not there.
“Again,” Gauss said.
This time Leo tried not to prepare.
The wall display showed that he had prepared anyway.
Gauss did not comment. He changed one setting and brought the assistance up by another step.
This story has been taken without authorization. Report any sightings.
They repeated the movement with the unloaded service rifle, then the electromagnetic shotgun. The frame supported their weight at Leo's shoulders and arms without choosing where either muzzle pointed. When Gauss cut assistance after warning him, both weapons became heavy again at once, joined by the dead mass of the suit itself.
Leo held his stance, though his knees flexed.
“If the collectors fail outside,” Gauss said, “you carry all of it home yourself.”
Leo shifted the shotgun's weight. “Including the suit.”
“Especially the suit.”
Leo returned the unloaded weapons to their clamps. The five rifle magazines and four shotgun cassettes remained sealed beneath them. He liked knowing they were there. He liked more that training had not already begun consuming them.
Gauss set a spare chest plate on the bench. It matched the suit around Leo except for a ragged hole through its center.
“Standard rifle test,” he said.
Leo leaned closer to the torn metal. “Same armor?”
“Same production layer. Angle and distance change the result. The useful conclusion is simpler: this suit is not rifle-proof.”
“Does it keep me alive?”
“It improves the chance.”
Not the answer Leo wanted. It was also the only honest one.
His own protection ended at the force of a service-pistol round. A stronger hit was not reduced. His protection simply stopped applying.
Gauss returned the ruined sample to the shelf. “Helmet down.”
The visor sealed over Leo's face and replaced direct sight of the test bay with a clean image assembled from the suit's cameras. Pulse and collector status stayed at the edges. The route detector on his forearm joined the display when Gauss activated the calibration field.
At first, the suit removed the interference. A faint haze vanished from the wall. The floor line sharpened.
Then a second line appeared beside it.
The service lock seemed to stand a little to the left of itself. FILTERED kept one door and erased the other. Leo switched the detector to RAW. Both doors returned, neither solid enough to trust.
The collector warning rose from green to amber.
Labels multiplied over the lock. CLOSED. OPEN. STRUCTURE PRESENT. NO STRUCTURE. The suit tried to align Leo's balance with two versions of the same floor, hesitated, and cut its own assistance.
SENSOR INPUT SATURATED
MOVEMENT ASSISTANCE LIMITED
Leo fixed his eyes on the real floor mark visible beneath the overlays and took one step back. The armor moved only because he moved it.
Gauss ended the calibration field. The false door disappeared. The visor kept the last reliable image until the cameras cleared.
“That was harmless input,” Gauss said. “In the field, saturation may come from corruption the collectors cannot reject. If the suit stops assisting, do not wait for it to become certain.”
Leo lifted the visor. “And if it stays certain about the wrong thing?”
“Use the physical evidence you can verify.”
Leo looked at the contradictory labels fading from the lock. “It displayed all of those perfectly.”
“That is the other limit,” Gauss said. “If meaning is the attack, the suit may help you see it more clearly.”
“Useful distinction,” he said.
“I prefer you learn it here.”
Gauss brought the detector histories onto the wall. Filtered mode showed one brief calibration fault. Raw mode preserved the doubled lock and, beneath it, the same intermittent carrier from the previous night.
With the suit's load cells active, they repeated the empty-case test once. The raw carrier rose with the weight transfer through Leo's arms and fell when he returned the case to the floor. Filtered mode kept the load trace and removed the matching carrier response.
“It is erasing a repeatable change,” Leo said.
“It is rejecting a change that contradicts the physical plan.”
“Those aren't the same thing.”
“No.” Gauss placed the two histories beside each other. “We keep both.”
The answer loosened some of the pressure the failed overlays had left behind Leo's eyes. Gauss tagged both histories for the next day's test. The lock timer remained active.
“I want raw mode available through the visor outside,” Leo said.
“It will give you false alarms.”
“Then I need to see what it calls false before I trust the cleaner answer.”
Gauss studied the paired histories, not Leo. “When raw and filtered geometry disagree, the frame can suspend assistance and preserve both displays. It will leave the choice to you.”
That meant more warnings and one less decision made invisibly inside the armor. “Do that.”
Gauss added the condition to the second day's calibration list.
Leo returned the case to the equipment bay. The large field dagger waited in its wall clamp.
“There's one more test,” he said.
Gauss turned from the detector histories.
Leo looked at the dagger. “I can change the next impact. I haven't tested it yet.”
Gauss's attention moved to the dagger, then back to Leo. “What result do you expect?”
“Something from the strike should pass through armor. The hit itself shouldn't become stronger.”
“Can you control which impact?”
“The next one.”
“Why the dagger?”
“Because I want the first contact where I can see it. A bullet adds too many ways to be wrong.”
Gauss brought an instrument block from the test-bay cabinet and fixed an ordinary armor shell over a dark witness sheet.
“The sheet registers anomalous contact,” he said. “It does not stop it. The armor is the only barrier.”
Leo drew the dagger. Gauss disabled movement assistance in his striking arm so the suit would record without adding force.
The first impact was ordinary. The dagger point hit the shell and stopped with a hard shock through Leo's wrist. It left a shallow triangular dent. The witness sheet behind it stayed dark.
Gauss saved the force trace. “That is our baseline.”
Leo reset his stance. The fourth mark tightened beneath his sleeve when he selected the dagger.
TECHNICIAN'S FRENZY
Selected carrier: reinforced field dagger
Cost: 1 anomalous energy
Next impact only
One unit was a small test until Leo counted how many small tests Meridian could demand. His reserve did not refill because a result was interesting. But learning the charge's limits while something was trying to kill him would cost more than one.
He confirmed the choice.
The number beneath the skin of his right wrist changed from 91 to 90. Nothing lit along the blade. Its weight did not change. Leo felt the charge settle between his palm and the hilt, fixed on the blade's next contact.
He struck.
The point stopped against the armor again. The shock in his wrist felt almost identical. Behind the unbroken shell, the witness sheet flashed blue.
For half a second, the outline of the dagger appeared on the far side of metal it had never crossed.
Then the light vanished.
The name had made the function sound like something that would seize his arm and choose violence for him. Instead, it had waited for a carrier and an impact. Leo had made both choices himself.
Gauss leaned over the readout. The two physical force traces lay nearly on top of each other. The second dent was no deeper than the first.
REAR ANOMALOUS CONTACT: CONFIRMED
“The blade did not penetrate,” Gauss said. “Something in the impact reached the witness layer.”
“That was the idea.”
“Can you repeat it?”
Leo looked at the lower number beneath his wrist. “It costs me. We already have the result.”
“One valid result is enough.”
Gauss saved the force curves, the witness response and the suit's motion, then ended the test.
By the time Gauss released the frame around Leo, the suit was less impressive and more useful. Leo knew how it could fail now. He also knew Gauss's calibration had kept the first mistake from becoming an injury and measured the charged impact more cleanly than Leo could have done alone.
Gauss opened the complete training archive on the equipment-bay wall.
Leo expected numbers. Instead, the suit rebuilt him as a pale moving figure. It showed every step through the test bay, the pressure beneath each foot and the changing angle of his balance. Pulse and breathing ran beside the body. A fine line at either hand recorded tremor.
Gauss replayed the moment the raw detector found the service-lock mismatch during saturation.
The figure approached the marked line. The carrier strengthened. Before the warning appeared, pressure began leaving Leo's forward foot. His other leg took his weight. His left hand closed hard enough for the glove sensors to record it.
Gauss paused the image.
“You began to retreat here,” he said. “The frame treated it as instability and prepared to correct you forward. I have removed that response when the detector reports spatial conflict.”
Leo searched his memory of the moment. Two doors. Too many labels. The floor line beneath them. He remembered deciding to step back only after the suit limited assistance.
“Did it know why?” he asked.
“No. It knows pressure, movement and stress. It does not know intention.”
Gauss added the raw segment to Leo's own training copy and closed the calibration controls. The field-service timer showed one full preparation day remaining.
On the wall, the pale figure shifted its weight away from the service lock.
The warning had not appeared yet. In Leo's memory, he was still standing still.
