Chapter 15: Signs of Overload

The signs of overload didn't appear where one would expect them to.

Not at the main generator.

Not at the red lines.

But at small points—where the system believed it was already sufficiently balanced.

It started with a series of synchronous delays.

Four minutes. Then six. Then twelve.

The modules were still running, but no longer synchronized. The dispatch panel updated slower than usual; a few warnings came after the event had passed. No one panicked. These delays were within acceptable limits, labeled by the system as cumulative delays.

Linh informed me at the end of the morning shift. “Nothing serious,” she said. “Just delays piling up.”

“How much?” I asked.

She opened the panel. “If aggregated, about 17% of the benchmark. But dispersed—so it didn't trigger the threshold.”

Dispersed. That word sounded very safe.

That same day, a maintenance team requested a shift postponement due to a shortage of personnel. A logistics employee changed their schedule because their child was sick. A nurse requested to leave early due to exhaustion. Each request had a reason. Each was handled individually. None was significant enough to become an incident.

The system accepted each request one at a time.

I walked past the engineering area. A young engineer sat in front of a monitor, his eyes red. He smiled when he saw me. “It’s fine,” he said before I could ask. “Just more things to monitor.”

More—but each thing less.

In the afternoon, the board held a brief meeting. Not to make a decision, but to provide an update.

“We’re in a stable state,” the chief engineer said. “But the safety margin is thinner.”

“How thin?” someone asked.

“Thin enough to be invisible,” he replied. “But enough to be felt.”

Medical presented exhaustion figures: a slight increase. Not exceeding the threshold. Logistics reported shipping delays: slightly increased. Not exceeding the threshold. Security reported absenteeism frequency: slightly increased. Not exceeding the threshold.

I looked at the curves. They were strangely similar: all inching up at the same small angle.

“Any suggestions?” I asked.

“Adjust the load,” logistics said. “Reduce output by 3% over two cycles.”

“That would hit the economic threshold,” one department head objected. “We’ve just stabilized.”

“Or short-term overtime,” another suggested. “Compensate with money.”

“Money can’t compensate for exhaustion,” medical said.

The options slid past each other. Each solved one part, exacerbated another. Balancing became a game of shifting weight on a tired scale.

Finally, they chose the most familiar option: micro-adjustments. Fine-tuning the schedule. Splitting shifts. Adding another layer of monitoring. No major cuts. No change in direction.

A safe decision. On paper.

That night, a minor incident occurred in the auxiliary cold storage. No complete loss of temperature. Just a ten-minute false alarm from the sensor. Ten minutes was enough to thaw a small portion of the pharmaceuticals that needed to be kept cold. No one was immediately affected. But a chain reaction had to be triggered, triggering another.

The system handled it smoothly. But when I reviewed the logs, I noticed something strange: the same person appeared in three different tasks within the same time slot—not due to cheating, but because the system had combined roles to compensate for a shortage of personnel.

“We’re using the same person for multiple places,” I told Linh.

“Within limits,” she replied. “Just… closer.”

Close. That word made me think of guitar strings.

The next morning, an employee fainted during their shift. Not life-threatening. Exhaustion. Medical staff responded quickly. The system recorded it as a personal incident—no operational impact. No chain reaction followed. No one would shut down the system because someone fainted.

But in the break room, I heard a phrase I rarely heard before: “Just a little more. Almost done.”

Almost done what?

Stability has no end point. It only has a level of maintenance.

At noon, I checked the Point of no return entry. That line was still blank. But right below it, a new entry appeared—not bold, not red:

System Load — Sustained High

No warning. No required action. Just a label.

I called Linh. “Is this new?”

“Yes,” she said. “It appears when multiple indicators are at the edge for an extended period. It doesn’t trigger anything. Just to… know.”

“Know for what?”

“So that later, if something happens, we can say we saw the warning signs.”

That statement sent a chill down my spine.

In the evening, I walked through the common area. There was less laughter. Not sad—just tired. Those who used to ask about Khoa no longer do. His file is still open, but no one mentions it. It exists as a silent symbol of the chosen balance.

I stand before the control panel, looking at the regular green lines. I remember the early days, when every decision made my hands tremble. Now, my hands are steady. Too steady.

The overload signal doesn't require immediate action. It only requires memorization. But memorization isn't something the system is good at.

I turn off the screen.

Outside, the base is still running—not noisy, not collapsing. Just… strained. Like something that's been stretched longer than it was designed to.

And I know: when a string breaks, it won't break at its thickest point.
