The machine hadn’t simply malfunctioned.
Someone had deliberately changed its operating parameters.
And whoever did it understood enough about the system to make the changes look like a legitimate commissioning adjustment.
That was the dangerous part.
A careless saboteur would have made obvious mistakes.
This wasn’t careless.
This was precise.
I didn’t touch another key.
“Everyone step away from the controller.”
Richard immediately protested.
“We paid you to fix it.”
“You paid me for diagnostics.”
I pointed at the screen.
“If I change anything before preserving the current configuration, you may lose evidence.”
“Evidence?”
His voice became sharper.
“Of what?”
I looked directly at him.
“Sabotage.”
The word seemed to suck the air out of Bay Three.
Walter slowly removed his gloves.
Mason stared at the floor.
Richard’s face hardened.
“That’s an irresponsible accusation.”
“It’s not an accusation.”
I opened my contractor laptop.
“It’s an observation.”
I started recording the machine’s current state.
Parameter by parameter.
Alarm by alarm.
Time stamp by time stamp.
Then I noticed something strange.
The altered parameters weren’t random.
They formed a sequence.
One adjustment affected the third-axis response.
Another affected the spindle synchronization.
The third affected the machine’s compensation table.
Together, they created a condition where the machine could pass basic startup checks but fail under high-load production.
Whoever had done it wanted the machine to appear healthy until the exact moment Meridian’s qualification run began.
Richard suddenly became very interested.
“How long to repair?”
“Maybe two hours.”
“Maybe?”
“I won’t give you a guarantee until I know what else was changed.”
“Ethan, Meridian’s people arrive tonight.”
“I know.”
“If we miss this run, we could lose the contract.”
“I know.”
“Then stop wasting time.”
I turned toward him.
“Richard, you fired the person who knows this machine best.”
His face reddened.
“Don’t make this personal.”
“You made it personal when you terminated me.”
Walter looked away to hide a smile.
Then Mason spoke.
“There may be something else.”
Everyone turned.
Mason swallowed.
“Yesterday afternoon, Tyler asked me for my commissioning password.”
I stared at him.
“Did you give it to him?”
“No.”
“Did he ask why?”
“He said Richard had authorized him to review the parameters.”
Richard immediately said, “I never authorized him to alter anything.”
I looked at Richard.
“I didn’t ask whether you authorized him to alter anything.”
The room became silent.
“I asked whether you authorized him to review the parameters.”
Richard didn’t answer.
That silence told me enough.
I walked to the machine cabinet.
There was a small service sticker on the inside panel.
I had placed it there during commissioning.
It contained a handwritten sequence I used to identify whether someone had opened the cabinet after final inspection.
I checked it.
The sticker had been peeled back.
Someone had accessed the cabinet.
And they had tried to put it back exactly where it had been.
Almost perfectly.
Almost.
There was a tiny crease in the corner.
I knew that crease.
I had made it myself.
My stomach dropped.
“Walter.”
“Yeah?”
“Who worked in Bay Three after midnight?”
Walter hesitated.
“Tyler.”
“Anyone else?”
He looked at Richard.
Then back at me.
“Richard was here too.”
Richard’s face went completely still.
I stared at him.
“You came into Bay Three last night?”
“I was checking the production schedule.”
“At midnight?”
“I was working.”
“Did you access the machine?”
“No.”
His answer came too quickly.
I turned back to the controller.
Then I noticed something buried in the diagnostic history.
A service login.
R. COLE — 00:43
I stopped breathing for a second.
Richard saw it.
His face changed.
“That’s impossible.”
I slowly turned around.
“You’re right.”
He stared at me.
“Because according to the access log, you didn’t just enter Bay Three.”
I pointed at the screen.
“You logged into the machine.”
Nobody moved.
Richard stepped toward me.
“That system is wrong.”
“Maybe.”
I zoomed in.
The login wasn’t the strangest part.
Under it was a second entry.
A parameter export.
Then another user login.
T. VANCE — 00:51
Tyler.
Two people.
Eight minutes apart.
I looked at Mason.
“Get me the original commissioning backup.”
He nodded and ran toward the engineering office.
Richard suddenly stepped in front of him.
“No.”
Mason stopped.
I stared at Richard.
“Why?”
“Because this is becoming an internal security matter.”
I laughed quietly.
“Interesting.”
“What?”
“You didn’t care about security when you fired me.”
Richard’s face hardened.
“I am the CEO of this company.”
“And I’m a contractor you just paid six hundred thousand dollars to diagnose the machine.”
I stepped closer.
“So right now, you don’t get to tell me what evidence I can preserve.”
The room went silent again.
Then Mason returned carrying a portable drive.
He handed it to me.
I plugged it into my laptop.
The original commissioning configuration loaded.
I compared it against the machine.
The differences appeared one after another.
Fourteen altered parameters.
Then I found something that made my blood run cold.
There was one final modification.
It hadn’t affected the machine yet.
It was scheduled to activate automatically during the Meridian qualification cycle.
I stared at the timestamp.
7:30 PM.
The exact time Meridian’s executives were scheduled to arrive.
If we did nothing, the machine would appear stable during inspection.
Then, when the production cycle reached its highest load, the hidden parameter would trigger.
The machine wouldn’t merely stop.
It could damage the spindle assembly.
Possibly destroy the entire production run.
I looked at Richard.
“Your problem isn’t a broken machine.”
He swallowed.
“What is it?”
I closed the laptop.
“Someone planned tonight.”
Richard’s phone rang.
He answered.
His expression changed after only five seconds.
“What?”
He listened.
Then slowly lowered the phone.
“Meridian’s team just moved their arrival forward.”
“To what time?”
“Six thirty.”
I checked the machine clock.
5:58 PM.
We had thirty-two minutes.
Then Richard looked at me.
For the first time since I had known him, he looked genuinely frightened.
“Ethan…”
I interrupted him.
“Don’t call me Ethan like we’re friends.”
He swallowed.
“What do you need?”
I looked at the machine.
Then at the altered configuration.
Then at the service log.
“I need the truth.”
Nobody answered.
And that’s when the lights in Bay Three suddenly went out.
Every screen went black.
Except one.
The machine controller flickered back to life.
A single message appeared on the display:
REMOTE OVERRIDE ENABLED.
And underneath it was a username I recognized.
ECole_Admin
My blood ran cold.
Because that wasn’t Richard’s account.
It was mine.
And I hadn’t logged in.
