A Missing Row Led Us To Two Trial Boats

"Did it connect to the helm?" I asked.

"We're checking," Zuri said.

"Check with the operators. The sales sheet won't tell you."

I sat at my kitchen table with my shoes still on. I could picture the harbor at dusk, the tight turns, the stern lights. A bad report felt much smaller on paper than it did beside moving water.

Helen arranged a call with Zuri and the two trial customers that evening. Each had used ChannelGuide in shadow mode. It watched live position data and offered routes on a separate screen. It had no control over either vessel.

The crews used their normal equipment for navigation.

I asked each manager to say that again for the notes. Then I asked whether any route from the trial screen had been followed. Both said no. Their deck logs and crew interviews would be checked too.

Only then did I take off my wet shoes. I had been pressing my toes against the kitchen floor hard enough to hurt.

Both operators agreed to pause the trials. Their staff preserved the trial laptops and logs before removing the software from service. One manager asked a question nobody had put on a slide.

"Was this report supposed to mean those suggestions were safe to follow?"

Zuri answered him plainly.

"It was used to support that claim. We are checking whether the claim was true. You will get a written correction."

She did not promise there had been no harm. She asked them to report any event or cost tied to the trial.

Neither reported an incident. They did report lost staff time.

The next day, Severn's examiner, Leila Grant, set up a secure video call. She had the copied files, the server records, and no interest in office rank.

"Explain a failed check," she told me.

"If a position fix gets too old, ChannelGuide should show a warning and stop treating that location as current. Our plan allowed three seconds."

"And if it keeps drawing a confident route?"

"That check fails. Even if the route looks neat."

She asked me to stay quiet while she ran the saved inputs.

I folded a boat below the camera, slowly enough that the paper did not crack.

One hundred checks ran. Eighty-eight passed. Twelve failed.

In the failed checks, the new ChannelGuide build had used an old position for as long as thirty-one seconds after the live signal became uncertain.

"Now the report builder," Leila said.

She ran the same results through the Keelglass package labeled 4.9.

Twelve rows disappeared.

The report showed eighty-eight green rows and a summary that said one hundred percent passed. The sales report had gone further and called that one hundred passing checks.

"Where did those twelve go?" Helen asked.

Leila opened a short script. A filter removed failed rows tagged UNCERTAIN FIX before the summary was made.

"That tag is the point of those checks," I said.

Graham, who had joined with company counsel, spoke for the first time.

"Bad sensor data shouldn't count against the product."

"The product was meant to warn about bad sensor data," I said.

No one spoke for several seconds.

Leila compared the package fingerprint to my release sheet. It did not match version 4.6. The file history showed the new filter had been added after my last approval.

"I need the change request," she said. "And whoever approved it."

Graham left the call.

Mira stayed. Her camera was off, but her voice was steady.

"I wrote the filter. There was a ticket. I said it would hide failures."

"Please provide the ticket through the review folder," Leila said. "Include the comments."

Mira did not excuse herself. She explained that she had expected a clearly marked sales demo, not an approval bearing my name. That did not settle her part in it. It gave the examiner a claim she could check.

Helen asked that no staff member be punished for taking part in the review. Zuri sent that request to the board.

I wanted to tell Mira she would be fine. I didn't know that yet. Instead, I thanked her for staying on the call.

The customer correction went out that afternoon. It named the report, withdrew its safety claim, and gave a number for costs and questions. The company reserved $60,000 for the two trial customers while their costs were checked.

At four, Daniel emailed a payment notice for my old invoices. The $24,000 would arrive in ten business days if I signed a full release.

Helen replied that an overdue bill was not a price for my silence.

I kept folding the same boat until its nose went soft.

At 5:18, Leila posted the change ticket and its full comment history.

Mira's warning was there. Daniel had answered, "Need green figures for buyer pack."

Below that, Graham had clicked Approve.

His note read, "Exclude uncertain inputs. Use Naoko's standard signoff page."
