Chương 12
Nathan looked at Sam.
"Could someone have been trying to recover stray records?"
Sam shook his head.
"Could be."
Nathan rubbed his face.
"Of course."
Danielle almost smiled.
"You get used to that word."
Owen said, "No, you don't."
Nobody disagreed.
Sam asked permission to photograph only the visible header and serial number without capturing technical contents.
Miriam approved that limited step after Danielle agreed.
Sam used a separate camera rather than his phone.
Then he compared the MedAxis serial structure against an archived parts catalog.
After several minutes, he pointed at the model family code.
"The knee actuator assembly belongs to the same hardware lineage."
Nathan leaned over his shoulder.
"Meaning?"
"The X9's current actuator is not identical to Caleb's."
"How close?"
"Same architecture family."
"So StrideCore inherited the design."
"Likely."
"And the fault behavior?"
"That's what we need to compare."
Danielle held up the folded printout.
"This shows it."
"Maybe."
She stared at Sam.
"You too?"
"I'm sorry."
"No, you're not."
"You're right."
She let out a breath through her nose.
"I hate careful people."
"Careful people hate themselves too."
That earned him a tired look.
Miriam said, "Danielle, I want to speak with you privately after this."
"About the agreement?"
"About whether we can locate its exact language."
Danielle hesitated.
"If I signed away the right to talk about what happened to my kid, what then?"
"Then we figure out exactly what you signed away."
"And if it's everything?"
"Then we work from public records and independently obtained evidence."
Nathan asked, "You're saying we might not be able to use what she knows."
"I'm saying knowledge and admissible evidence are not identical."
He started pacing again.
Danielle watched him.
"Don't do what my husband did."
Nathan stopped.
"What?"
"Turn this into a war because war feels better than waiting."
His face closed.
"You don't know me."
"No."
She tucked the printout back into her pocket.
"I know that walk."
Nathan looked toward the window.
"My son could have been hurt."
"So could mine."
"He was."
"Yes."
Her voice did not rise.
"That's why I'm telling you."
He looked at her again.
Danielle continued.
"My husband spent the first year after Caleb's fall trying to destroy MedAxis."
Nathan's jaw tightened.
"Did he?"
"No."
"What happened?"
"He destroyed us for a while."
Owen's eyes moved between them.
Danielle seemed to notice him and stopped.
Nathan did not ask for details.
That was probably the first useful decision he made all morning.
Sam returned to the X9 data.
"There's another possibility we haven't discussed."
Nobody liked the way he said it.
"What?"
I asked.
"StrideCore may not have intentionally selected Owen for a risky test."
Nathan folded his arms.
"Go on."
"If their system automatically classified users based on gait metrics, the deployment platform might have assigned build 7E according to profile criteria."
I stared at him.
"Automatically?"
"Could be."
"So no engineer had to look at Owen's report and choose him."
"Right."
Nathan frowned.
"How is that better?"
"It may be better legally for intent."
Sam paused.
"Not necessarily better for safety."
I looked at the March thirteenth report.
High-load variance.
Left knee transition.
Conservative assist settings.
If those fields fed into an automated classification system, the warning itself might have become the reason Owen received the experimental configuration.
I felt sick.
"What if the system interpreted risk as eligibility?"
Sam looked at me.
"That's exactly what I'm wondering."
Nathan stopped pacing.
"Say that in English."
I turned the laptop toward him.
"My report said Owen's left knee behavior was less predictable under fatigue."
"Yes."
"If StrideCore's deployment system was looking for high-variability pediatric gait profiles, it may have tagged him because of that."
Nathan stared at the screen.
"So the information meant to make them more careful could have put him into the pilot."
"Possibly."
He closed his eyes.
This time he did not complain about the word.
Owen looked at me.
"Did you make them pick me?"
The question hit harder than anything else had.
"No."
I answered too quickly.
He heard it.
I tried again.
"I sent them information to keep you safe."
"But they used it."
"We don't know that."
"But maybe."
There it was.
I looked at him.
"Maybe."
He lowered his eyes.
I could have told him none of this was his fault.
I could have told him it wasn't mine.
Neither sentence would have helped.
Instead, I said, "I wish I had checked what happened after I sent those reports."
"You didn't know."
"No."
"Then how could you check?"
I had no answer.
Owen looked at the mechanical brace on the counter.
"Does yours get updates?"
"No."
"Does it call the internet?"
"No."
"Does it know how I walk?"
"Only if I adjust it after watching you."
He considered that.
"Can it lock?"
The question made me pause.
"Yes."
His head lifted.
Nathan looked at me sharply.
I continued.
"Any brace with a joint can fail or jam if something goes wrong."
Owen frowned.
"Then why is yours better?"
"I didn't say it was."
"You keep working on it."
"Because I understand every part of it."
"That's not what I asked."
He was right.
I leaned back.
"It isn't better just because I built it."
He waited.
"It has different risks."
"What risks?"
"It can't add power the way the X9 can."
"So harder walking."
"Yes."
"It won't catch me if I'm too weak."
"Not by itself."
"What else?"
"It can fit badly."
"It can rub your skin."
"A hinge can wear out."
"A strap can loosen."
"I can make the wrong adjustment."
Owen looked at Nathan.
"She says bad things about her own machine."
Nathan's face changed.
Just slightly.
Danielle saw it too.
Owen looked back at me.
"Can I try it?"
Nathan said, "Not now."
I said the same thing at the same time.
Owen rolled his eyes.
"Everybody agrees when it's annoying."
I touched the brace.
"We'd need your physician and therapy team involved."
May you like
"And no walking today."
"No walking today."
