Chapter 4 - THE ENGINEER
Julia Reyes no longer worked for Northstar Training Systems. She lived in Tennessee and operated a small industrial-controls consultancy, which made finding her easier than convincing her to talk. Seth handled that part himself because he had finally stopped pretending the problem belonged only to the people who wanted answers from him.
His first email received no reply. The second included the exact sentence from Luke's voice memo about the red controller. Julia called twenty-three minutes later and opened with a question rather than a greeting. “Who else has that recording?”
Seth told her Mara Barrett had the original file. Julia asked whether anyone from Northstar knew it existed, and Seth said probably not. Her silence confirmed that she considered that good news.
They met the following day at a roadside restaurant halfway between cities. Miller drove because Seth's knee was worse after several hours behind the wheel, while Mara brought Luke's recovered phone and a printed copy of the old incident summary. Julia arrived alone and chose a booth where she could see both entrances.
She remembered Seth immediately.
“I testified that the system passed diagnostics,” she said.
“It didn't,” Seth replied.
“No.”
That answer changed the tone of the meeting before anyone finished ordering.
Julia explained that Northstar's Atlas breaching controller used a wireless safety interlock designed to prevent a training charge from firing if any participant crossed designated electronic boundaries. Three weeks before Luke's death, a firmware update began producing intermittent false-clear signals. The safest response would have been to remove the affected controllers from service, but Raven Ridge was hosting military evaluators and Northstar had a major renewal contract under review.
Wes Harlan ordered engineers to perform manual resets instead.
Julia objected in writing.
Her supervisor changed the maintenance report from SYSTEM FAULT to OPERATOR CALIBRATION ERROR.
That was the first deliberate concealment.
Mara asked why Julia testified that the controller was safe after Luke died. Julia looked down at the table before answering. Northstar's attorneys showed her a diagnostic printout indicating the system registered Seth's boundary breach immediately before the detonation. They told her investigators had already determined human error caused the accident and warned that claiming otherwise without the original controller logs could expose her to accusations of altering safety records.
“You knew about the earlier faults,” Seth said.
“Yes.”
“And you said nothing.”
“I said less than I knew.”
Julia did not ask for forgiveness. That made Seth listen more carefully.
She had preserved copies of several maintenance emails on a personal drive because she feared Northstar would blame engineering staff if another failure occurred. The emails proved repeated faults and Harlan's insistence on keeping the system operational. They did not prove what happened during the final exercise because the controller's event log should have contained the crucial timestamps, and that data vanished after the accident.
“Who had access to erase it?” Miller asked.
Julia answered that Northstar's local administrator, the facility systems manager and Harlan himself all had credentials. Military investigators received only a printed event summary generated by Northstar, not the raw database.
Seth unfolded the old incident report. The summary listed his boundary crossing at 21:19:14 and the detonation at 21:19:16, a two-second sequence that made the official conclusion look straightforward. Julia examined the page and immediately pointed to something no one else had noticed.
The time format was wrong.
Atlas controllers stored events to the millisecond and displayed twenty-four-hour timestamps with three decimal places. The official report used whole seconds because someone had copied selected events into a manually prepared table.
“That isn't the raw log,” Julia said. “It's somebody's summary of the raw log.”
The mystery moved from missing evidence to potentially reconstructed evidence.
Seth asked whether another system might have recorded the same exercise. Julia remembered that Atlas communicated with a separate scoring platform used to track team movement and target engagement. Northstar did not own that software; a smaller company called MetricFire supplied it.
“Would it have the detonation event?” Mara asked.
“Not directly. But it should have every boundary beacon and target-state change with independent timestamps.”
Seth felt the first real possibility of proving sequence rather than arguing memory.
Then Julia complicated it.
MetricFire had been acquired five years earlier and its original cloud service had been shut down. She did not know whether old customer data survived.
Before they left, Julia gave Seth copies of her maintenance emails. One message from Harlan, sent nine days before Luke's death, read: Do not take the red units offline during evaluation week. Manual reset is acceptable until contract decision.
That document proved Northstar knowingly kept malfunctioning equipment in service.

It also proved the accident had not begun with Seth crossing a line.
Someone had already decided risk was cheaper than delay.
