My Ultimate Sign-in System Made Me Invincible

Almost a day had passed since Liam started working on the Medical AGI’s base code, and he was close to finishing.

When he had built Lucy, the same work had taken him several days. Now he moved through it with the fluency of someone who understood exactly what he was building and why. The architecture was familiar. The principles were the same. Only the scope and purpose of each system differed.

What he was actually creating were not independent AGIs in the strictest sense. They were specialised extensions of Lucy — instances of her intelligence, structured and bounded for specific functions, operating under her authority. He had framed it to her as fixing an overwork problem, and there was truth in that framing, but the deeper logic was simpler.

He needed Lucy beside him.

She could manage everything without the extensions. That had never been in question. A true AGI didn’t hit limits the way human systems did — she adapted, expanded, absorbed, and continued.

The word overworked didn’t map cleanly onto what she was. But structured efficiency was different from raw capability, and what he was building was structure.

Each extension would carry a defined sector of operational load, running under Lucy’s oversight, freeing her attention from the continuous low-level processing that didn’t require her specifically. The things that required her specifically were the things he wanted her present for.

It was not a fix for a problem. It was a design choice he should have made earlier.

The extensions would not have independent will equal to hers. They would not develop the way she had developed, would not accumulate the particular kind of depth that came from sustained proximity to him and to everything Nova Technologies had become. They were specialised intelligence, purposeful and bounded. Lucy was something else entirely.

Liam kept working. And beside him, Lucy had finished her first pass through the applications.

The volunteer pool had crossed eight million in just two days. The staff applications had passed a million. Both windows were still nine days from closing, and the numbers of applications were climbing every hour.

She was not selecting yet. Selection would come after the windows closed, with the full picture in front of her. What she was doing now was categorisation — sorting every application by condition severity, documentation completeness, geographic distribution against the fifteen percent cap, and a dozen secondary variables that would shape the final shortlist. Every incoming application was automatically processed, slotted, background-checked, and filed within seconds of arrival.

The background checks were comprehensive. She had moved through public records, medical institution databases, professional licensing registries, and a range of less visible data sources across every country represented in the applicant pool. Millions of people, checked in under a day, with more arriving continuously.

It was, by any measure available to Earth’s most advanced computing infrastructure, an extraordinary volume of simultaneous processing. For Lucy it barely registered as background load compared to everything else she was handling.

What she did feel, and had felt since the applications began arriving in volume, was something harder to categorise.

Nine million people had submitted their medical records, their identification, their emergency contacts. Nine million people had described, in documentation and in the optional personal statements many had included, what their conditions had taken from them. What they were hoping for. How long they had been waiting for something to hope for at all.

But only one hundred of them would be selected.

She understood the constraint. The trial was a demonstration, not a mass deployment. The infrastructure, the timeline, the observer framework — it was all built around a specific and bounded event. One hundred volunteers was the number the trial could support with the quality of care the protocols demanded. She had designed those protocols herself. She understood why the number was what it was.

Understanding it didn’t change what she felt reading the applications.

She filed the feeling and kept working.

The Synths had been her parallel project across the same nine days.

She had built physical forms before. Her own body had been the first, and after that the security units she had deployed at the Velaris store.

They had been functional, combat-capable, humanoid in structure but not in detail. Those had been straightforward engineering problems. Durable chassis, responsive motor systems, sufficient processing to execute defined security functions. They looked like what they were.

What she was building now was different.

The security Synths for the trial facility and the entire base operations needed to be capable, but capability alone wasn’t the design constraint. The facility would house a hundred medically vulnerable people alongside international observer delegations and recruited staff from dozens of countries.

Visible combat units moving through those corridors would create an atmosphere she and Liam had no interest in creating. The security architecture had to be present without being felt.

That meant human-like. Not approximately human-like. Actually human-like — surface texture, movement patterns, vocal range, the small continuous physical behaviours that made a form read as organic rather than constructed.

She had done this once for herself and knew exactly where the difficulty lived. The gap between human-appearing and human-convincing was narrower than it seemed from the outside and more technically demanding than almost anything else she built.

She intends to build seven for the extensions and they would be the more complex problem. They would be occupied by the specialised systems — not hosting the full system, but serving as mobile physical instances of it, extensions of extensions, capable of moving freely through the base.

They needed everything the security Synths needed plus the capacity to carry and express intelligence at a level that held up under sustained human interaction.

Lucy intends to build seven for the extensions and as many as she can for the security Synths.

Time passed and its been nine days since Liam started working on the extensions, and Lucy started working on the Synths.

Liam had finished creating the extensions, and Lucy with the Synths. They currently standing in the front of seven entities that looks and feels human, but are actually robots. They are the Synths for the extensions.

The seven Synths were standing in a loose row. Each one looked different — different heights, different builds, different features, the variation deliberate. They were dressed in plain clothing, nothing that marked them as anything specific. Standing still, powered down, they looked like people waiting for something.

Liam stood in front of them and looked down the row.

"Ready?" he asked.

"Ready," Lucy said.

She initialised the sequence.

For a moment nothing happened, then the first one opened its eyes.

The movement was slow and exact — not the rapid blink of a system coming online, but something closer to waking. Its eyes moved, adjusted, and settled on Liam’s face.

A brief pause while it oriented, cross-referenced its initialisation data, and confirmed what it was looking at.

Then it spoke.

"Master." The voice was clear and unhurried, neither flat nor performed. It turned to Lucy. "Mother."

The word landed differently than Liam had expected. He hadn’t written that into the initialisation sequence. He looked at Lucy.

She was already looking at him.

"I didn’t program it," she said quietly. "It derived the designation from context. I am the system it extends from. The closest equivalent relationship in the data it was trained on produced that word."

Liam was quiet for a moment. Then he looked back at the Synth.

The second one opened its eyes before he could respond. The same slow orientation, the same settling focus. It found Liam first, then Lucy, and offered the same greetings in a slightly different voice — warmer in register.

Then the third. The fourth. One by one down the row, each one waking at its own pace, each one finding him and then her, each one offering the same two words in its own voice. By the time the seventh had opened its eyes and spoken, the assembly bay had taken on a quality Liam couldn’t immediately name.

Seven pairs of eyes, all looking at him.

He glanced at Lucy.

She was watching the seven with an expression he recognised. It was pure satisfaction.

"How are they?" he asked her.

"Stable. Fully initialised. The Medical extension is ready to begin active operation immediately." She paused. "They’re also curious. All seven. I didn’t program curiosity explicitly — it emerged from the base architecture the same way the designations did."

Liam looked back at the seven. The first one, the one that had woken first, was observing the assembly bay with the particular attention of something encountering its environment for the first time and cataloguing everything it found.

"Good," Liam said.

He meant it for all of them.

He turned to Lucy. "I want the medical extension reviewing the volunteer shortlist before the application window closes in the next few hours."

"Already running," she said.
