Espinoza ran the screening himself.
Not because he didn't trust his medical staff. Because two years of diagnostic assumptions had just been contradicted by a woman with ordered blue veins, and Major Espinoza was the kind of doctor who needed to see the data himself before he believed it was real.
The screening took six hours. Every person Erik had healed, brought to the medical building in groups of twenty, scanned with the compound's standard mana-resonance equipment. Chen stood beside Espinoza for every scan, her own scanner running parallel readings, the two datasets cross-referencing in real time.
Erik wasn't allowed in the medical building. Vance's order, delivered through a soldier who'd been polite about it. Medical screening fell under Espinoza's authority, but the screening location fell under compound security, and compound security was martial law territory.
Tank sat with Erik in the quarters. Waiting. The soldier and the EMT, doing what soldiers and EMTs did between emergencies: counting time and trying not to count it.
"Thirty-one," Chen said when she came back.
She stood in the doorway of Erik's quarters at 1600 with the scanner case under her arm and the look of someone who'd been recalibrating her understanding of biology for six straight hours.
"Thirty-one out of two hundred and thirty-seven show signs of latent resistance activation. The markers are consistent with what we saw in Daraâordered mana-processing channels forming in tissue that was previously classified as susceptible." She set the scanner case on the desk. "Not all thirty-one are at the same stage. Twelve show strong activation. Fourteen show moderate. Five show early-stage development that may or may not progress." She paused. "But they're all doing it. Their biology is building the same structures. Without the framework. Without Warden intervention. On its own."
"Thirteen percent," Erik said. Thirty-one out of two thirty-seven.
"Of the people you healed. The compound has approximately eight hundred susceptible residents total. If the same rate holds across the full populationâ" She did the math in her head. "âapproximately one hundred and four people in this compound may be developing latent resistance."
Tank leaned forward. "And nobody knew."
"Nobody tested for it. The original susceptibility screening was binary: resistant or susceptible. Yes or no. Nobody designed a test for 'susceptible but potentially adapting under higher mana concentrations' because two years ago the mana concentrations weren't high enough to trigger it." Chen opened her scanner. The data still on the display. "Espinoza isâhe's reassessing. That's the word he used. Reassessing."
"Reassessing what?"
"Everything. The classification system. The treatment protocols. The assumption that susceptible equals terminal without intervention." She looked at Erik. "He's been treating susceptible patients for two years under the assumption that they were all declining toward Stage 2. Some of them were. But some of them might have been developing resistance channels that his standard screening missed because nobody was looking for them."
"And when the mana spikedâ"
"The spike pushed the latent process into visible territory. The higher concentration provided the pressure that the adaptation needed to become detectable." She closed the scanner. "Espinoza wants to screen the full compound. All eight hundred susceptible residents. He's requesting Vance's authorization."
"Vance won't give it," Tank said.
"Espinoza outranks the staff who'd need to block it. Medical screening authority is specifically exempted from martial law restrictions under the charter's public health provisions." Chen paused. "Okonkwo looked it up for him. Apparently, they've been talking."

By 1800, half the compound knew.
Not from an official announcement. From the way information moved in a settlement of twelve hundred people behind the same walls: hallways, shared meals, the low urgent conversations that happened when something new broke in a place where nothing new ever happened.
Erik heard it from the corridor outside his quarters. Two soldiers at the checkpoint, talking in the low voices of people who thought they were being quiet.
"âthirty-one of them. Adapting. Like their bodies are figuring it out."
"My sister's susceptible. She's in Block C."
"Everyone in Block C is getting screened tomorrow. Espinoza's doing the full compound."
"Does Vance know?"
"Vance knows everything. Question is what he does about it."
Erik went to the window. The compound was doing its evening routines, but the texture was different from last night. People in doorways. Small groups on the walkways between buildings. The particular posture of a population that was talking about something that mattered and that nobody in authority had told them about, which made it feel more real than if it had come through official channels.
Thomas found him at 1900.
The civilian liaison looked different from the man who'd sat in the council meeting two days ago with blue veins on his wrist and the hunted expression of someone who'd been given a job nobody wanted. His veins were still there, faded from Erik's healing, the faintest blue tracery. But his posture had changed. The man who'd been appointed to represent the civilian population had apparently decided to start doing it.
"I'm organizing a meeting," Thomas said. "Civilian population leaders. Block representatives. Tomorrow morning."
"Vance won't authorize it."
"Vance doesn't need to authorize civilian assembly under the charter's mutual-aid provisions. Okonkwo confirmed." Thomas stood straighter than he had in the council chamber. Not a big change. Inches. But the inches mattered. "People are asking questions. Why hasn't anyone tested for latent resistance before? Why has the medical response been 'you're susceptible, here's a bed, wait for it to get worse'? Why has the Director been spending resources on walls instead of screening?"
"Those are good questions."
"They're questions the civilian population has a right to ask." Thomas paused. "I'm not starting a revolution, Shaw. I'm doing my job. The council is suspended, but the civilian liaison role predates the council. It's in the original Sanctuary charter. Vance can suspend governance. He can't suspend the right of the civilian population to organize for mutual aid."
"Okonkwo found that too."
"Okonkwo has been reading the charter all day. She says there are fourteen provisions that martial law doesn't cover." Thomas almost smiled. Almost. "She's a very thorough reader."
He left. Erik watched him go. Thomas walked faster than he had in the council chamber. Straighter. A man who'd found something to do and was doing it before anyone could tell him to stop.
Tank appeared in the doorway. "The political ground is moving."
"Yes."
"Vance can feel it. His patrol frequency has increased by twenty percent since this afternoon. More checkpoints. More visible presence." Tank looked at the compound through the window. "He's tightening because things are loosening. That's the pattern."
"How tight can he get before it breaks?"
"Depends on how many of his soldiers agree with what he's doing." Tank turned from the window. "Some of them are susceptible too. Some of them have families in the residential blocks. The screening results mean something different to a soldier whose wife just found out she might be adapting instead of dying."

At 2100, Chen came back with the scanner and the framework data.
"I've been mapping the new sections that arrived today," she said. "The transfer is at nineteen percent now. The data structure is becoming more complete." She sat on the floor. The floor was where Chen worked when the work mattered, the same way she'd mapped his architecture on the first day. "I found something in the new data."
"Good or bad?"
"Both. The framework includes metadata. Not just the resonance pattern itself but annotations. Notes from the developer." She looked at the scanner display. "Kael left comments in the framework data. Embedded in the transfer structure. Notes on the framework's development, the testing parameters, the expected outcomes."
"He annotated his own research."
"Scientists annotate everything. It's how we make sure the next person can understand what we did and why." She scrolled through the display. "Most of the annotations are technical. Frequency parameters, biological response models, synchronization tolerances. But there's one that's different."
She turned the display toward him.
The annotation was in the Warden's data-encoding format, which Chen had been learning to read for weeks. She'd translated it into standard text on a separate display:
*WARNING â TRANSFER MORTALITY RISK*
*The compatibility framework produces successful adaptation in the majority of recipients. Testing on available subjects (N=347) produced a consistent mortality rate of approximately 3% (N=11). Mortality occurs during the transition phase, when the recipient's biology is reorganizing to accommodate the new mana-processing architecture. In susceptible individuals whose biology cannot complete the reorganization within the transition window, the resulting mana shock is fatal.*
*This mortality rate persisted across all tested variations of the framework. Modifications to the resonance pattern, the channeling intensity, the synchronization parameters, and the transition window duration did not reduce the rate below 3%. The mortality appears to be an inherent limitation of biological variation â approximately 3% of any susceptible population lacks the genetic capacity to complete the adaptation process, regardless of how the framework is implemented.*
*I could not eliminate this cost. I tried for two years. The framework saves 97 out of 100. The 3 who die would have died from mana sickness regardless, but they die faster during the transition than they would have from natural progression.*
*This is the cost. I could not make it zero.*
Erik read it twice. Three times.
Three percent.
"Kael tested it on three hundred and forty-seven people," Chen said. Her voice was the voice of a scientist delivering findings she'd verified and couldn't dismiss. "Eleven died. The mortality rate was stable across all variations. He spent two years trying to eliminate it. He couldn't."
"Three percent of the susceptible population."
"Three percent of anyone who receives the framework treatment. The people who are developing latent resistance on their own may have lower risk, because their biology has already begun the adaptation process. But for standard susceptible individualsâthose who need the full framework treatmentâthree percent."
Erik sat on the cot. The number sitting with him.
Three percent of Sanctuary Prime's eight hundred susceptible residents was twenty-four people. Twenty-four people who would die during the treatment that was supposed to save them. Not from a failure of the framework. From biology. From the genetic lottery that had determined, ten thousand years ago, which humans could adapt and which couldn't.
"Global susceptible population," he said. "Current estimates."
"Approximately four point five billion, based on the ninety-percent susceptibility rate applied to the surviving global population." Chen's voice was flat. The tone of someone who'd already done the math and was giving it to him because he'd asked. "Three percent of four point five billion is one hundred and thirty-five million."
One hundred and thirty-five million.
The framework would save the rest. Four point three billion people, given the ability to process mana safely, their biology taught by a ten-thousand-year-old resonance pattern channeled through two Warden architectures. The mana sickness ended. The Turning stopped. Humanity compatible with the world it lived in for the first time since the Return.
And one hundred and thirty-five million would die in the process.
"Kael knew," Erik said.
"Kael knew. And he still developed the framework. And he still encoded it in the seal's failsafe." Chen closed the scanner. "Because the alternative is one hundred percent mortality. Every susceptible human eventually progresses to Stage 2, then Stage 3, then Turning. The framework's three percent failure rate is against a baseline of complete loss."
"That doesn't make the three percent less dead."
"No." Chen looked at the scanner in her lap. The data that contained Kael's annotations, Kael's warning, Kael's two years of trying to eliminate a cost he couldn't eliminate. "No, it doesn't."
Tank was in the doorway. He'd heard. The soldier who counted things, bullets and exits and patrol rotations, stood in the doorway with the number on his face.
"Twenty-four," Tank said. "In this compound."
"Yes."
"We'd be choosing twenty-four people to die."
"We'd be choosing to implement a treatment that saves seven hundred and seventy-six people and fails on twenty-four." Erik looked at Tank. "And we wouldn't get to choose which twenty-four."
The room was quiet. The compound settling into its curfew routines. The checkpoints logging movement. The Antarctic alert broadcasting on, steady, the seal's failsafe continuing to write the framework into Erik's architecture one frequency at a time. Twenty-three percent complete now. The percentage climbing. The data accumulating. The resonance pattern that would save ninety-seven percent of humanity and kill the other three writing itself into his body with the steady, indifferent precision of a system that had been designed to deliver exactly this, and that included the warning because the person who built it had wanted the person who used it to know the cost before they paid it.
Kael had wanted that.
Kael had wanted the next Warden to sit with the number the way Erik was sitting with it now, in a small room in a compound full of people who were counting on him, and to know that saving them meant choosing a number of them to die.
Not choosing who. The biology chose that. But choosing to begin. Choosing to say yes, three percent is a cost I can carry. Or choosing to say no, and watching the hundred percent take them all.
The EMT's choice. The ambulance arriving at a scene with twenty casualties and three medics, and the triage that meant some people got treated and some people didn't, and the ones who didn't had faces and names and families and the fact that saving the others was the right call didn't make the faces go away.
Erik had made that call before.
He'd never made it for a hundred and thirty-five million.
He looked at the scanner on Chen's lap. The data. The cost. The number that Kael had carried for ten thousand years, encoded in a failsafe, waiting for someone else to carry it.
"We tell them," he said. "Everyone. The compound. The council, when it reconvenes. The installations. The full number. The cost."
"Vance will use it against you," Tank said.
"Vance should use it against me." Erik's voice was quiet. The near-whisper. "Because it's real. The cost is real. And anyone who's going to be asked to take the treatment has the right to know that three out of a hundred won't make it."
The compound was dark outside the window. Eight hundred susceptible people in their beds, some of them with blue veins fading from his healing, some of them with ordered channels building in their tissue, all of them trusting that someone was working on the answer.
Twenty-four of them wouldn't survive the answer.
He didn't know which twenty-four. Nobody could know. But somewhere in the compound, sleeping in their bunks, going about their curfew routines, there were twenty-four people whose biology had been determined, by a genetic lottery older than civilization, to be three percentage points short of survival.
And tomorrow he was going to tell them that the cure existed, and that it cost exactly this much.
He sat on the cot with the number and he didn't sleep.
