The bait node wanted to be a sphere.
Voss could see it through the Reality Sight — the Weaver architecture organizing itself according to principles that favored radial symmetry, the thread-energy channels arranging in concentric shells around the central anchor point like layers of an onion. Nira Sol was building it the way Weavers built everything: from the inside out, structural principle first, material expression second. The energy would come last, flooding the channels once the architecture was stable.
They were in the hills forty kilometers north of the city. No roads. No structures. A clearing in old-growth forest where the ground was granite and the nearest human settlement was a ranger station twelve kilometers south. Ryn had vetted the site from the transport and approved it with the clinical brevity of someone who evaluated terrain the way Voss evaluated tissue: by how much damage it could sustain before failure. The clearing would absorb the Gradient's drainage without collateral.
He was assisting. Not building — he lacked the Weaver's capacity to generate thread-architecture from raw substrate. But the Reality Sight let him read what Nira Sol was constructing at a resolution she could not achieve from outside the structure. He was her mirror. She built a layer. He read it. He told her where the channel tolerances were tight, where the energy distribution would create hotspots under the triple-capacity load, where the connection points to the existing network needed reinforcement.
It was the closest thing to carving he had done in weeks. He missed the work.
"The eastern channel cluster is running twelve percent above optimal density," he said. "If you redistribute the lower third to the secondary branch, the load will balance."
Nira Sol adjusted. Her thread-architecture shifted into the construction mode he had cataloged over the past week — the cognitive threads directing fine manipulations of the substrate, each adjustment precise, each movement informed by an architectural knowledge that spanned eons. She worked the way a master surgeon worked. He recognized the quality. Controlled. Unhurried. Every cut intentional.
The channel cluster smoothed. He read the change and confirmed it. "Clean."
They worked for another hour. The bait node took shape — a sphere of Weaver architecture anchored to the granite bedrock, its channels configured to hold three times the standard energy output. When activated, it would burn brighter than any node in the network. A beacon in the dark.
A meal.

He asked during a pause in the construction. Nira Sol had stopped to run an internal calibration — a periodic process where her architecture verified its own precision, the way a surgeon checked their instruments between procedures. He waited until the calibration was complete, until her attention was fully available.
"Structural reinforcement," he said.
Her thread-architecture changed.
He had cataloged many of Nira Sol's thread patterns over the past ten days. The instructional mode. The alert configuration. The analytical processing state. The communicative precision that meant she was choosing her words. He had not seen this one.
The cognitive threads pulled inward, but not in the alert pattern — that was a tightening, a preparation for unexpected information. This was different. The threads folded in a way that reduced their surface area, as if the architecture was protecting something internal from external observation. A closing. The structural equivalent of a person crossing their arms.
She knew the term.
*Where did you encounter this?* she sent.
"An archive. A six-hundred-year-old Carver report from the period when the original doorway network was sealed. It described a phenomenon consistent with Gradient activity and mentioned a technique called structural reinforcement that human Carvers attempted. The full report is incomplete — the last pages were removed by a Weaver liaison officer two hundred years ago."
He delivered this without accusation. Facts. Nira Sol could read his thread signature well enough to know that he was stating what he had found, not assigning blame. The information gap was the data. What she did with it was her choice.
She was quiet for twenty seconds. Her internal processing ran at densities he could observe but not follow — multiple channels operating simultaneously, the parallel architecture that let Weavers think in ways human cognition could not replicate. She was not consulting the Loom. She was consulting herself.
When her threads reopened, the configuration had changed again. Not the closed defensive posture. Not the instructional mode. Something he read as deliberate transparency — the cognitive architecture arranged to minimize filtering between thought and communication. She was choosing to be direct.
*I know the term*, she sent. *I know what it is. I did not volunteer the information because the technique carries a cost that the Weavers consider ethically unacceptable. The decision not to teach it was made collectively, and I agreed with that decision. I still agree with it.*
"Tell me anyway."
*Yes. You have earned the information.* A pause. Not hesitation. Organization. *Structural reinforcement is a technique that was developed independently by human Carvers in three separate dimensions where the Weavers maintained partnerships. In each case, the Carvers discovered it without Weaver instruction. In each case, the Weavers subsequently learned of it. In each case, the Weavers chose to discontinue the technique and remove records of its development from accessible archives.*
"Including from our archives."
*Yes. The pages removed from your historical records were removed by a Weaver liaison acting on a standing directive. I will not defend the removal. It was a decision. Whether it was the right decision is a question I have not resolved.*
He respected the honesty. "What does the technique do?"
---
Nira Sol moved one step closer. The reduction in distance had become familiar — it meant precision of communication, the narrowing of signal-to-noise ratio that came with proximity.
*A Gradient consumes organized thread-energy from the substrate. After it passes, the affected area is depleted — the organizational principle that structures matter at the fundamental level is absent. The substrate is still there. The atoms, the molecules, the physical material. But the Loom's organizing radiation is gone. The structure of the space has been unraveled at the deepest level.*
"I've read this. The Greywater node."
*Yes. The standard Weaver response is to allow the depleted zone to recover naturally — the Loom's radiation slowly re-saturates the area over years, rebuilding the substrate. Or to isolate and sacrifice. There is no Weaver method to actively restore consumed substrate. Our architecture is not compatible with the process required.*
"But human architecture is."
*Biological neural architecture that carries Thread Sight operates at a frequency that interfaces with the Loom's substrate in a way that Weaver architecture does not.* She paused. The deliberate transparency in her threads held steady — she was not filtering this. *A human Carver with sufficient Thread Sight can read a depleted zone, identify the absent organizational patterns, and generate those patterns from their own neural architecture. The Carver's biological thread-energy is structurally compatible with the substrate. It can substitute for the consumed Loom radiation. The Carver re-weaves the depleted zone using themselves as the thread source.*
He understood the mechanism immediately. It was Thread Surgery, scaled up. Thread Surgery involved reading corrupted thread-patterns in human neural architecture and cutting them free — a destructive intervention. Structural reinforcement was the constructive inverse: reading absent thread-patterns in the substrate and filling them in. Same principle. Opposite direction. Instead of removing what should not be there, you supplied what should.
"It works," he said. Not a question.
*It works. In each of the three dimensions where human Carvers developed the technique, they successfully restored substrate in areas that Gradient activity had depleted. The restored zones were stable. The Gradient's passage was reversed. The dimensional fabric was repaired.*
"And the cost."
Nira Sol's threads tightened. Not the defensive closure from before. A controlled contraction, the way a person's voice tightened when they were about to say something they wished they did not have to say.
*The cost falls entirely on the Carver.* She was precise. *The thread-energy used to restore the substrate comes from the Carver's own neural architecture. Their biological thread-patterns — the resonance frequencies that enable Thread Sight — are drawn into the depleted zone and integrated into the restored substrate. The Carver patches the hole with their own cognitive material.*
He sat with this.
*The degradation is permanent*, Nira Sol continued. *Each application of structural reinforcement reduces the Carver's neural thread-density. The reduction is proportional to the size of the depleted area being restored. A small restoration — a single node's worth of depletion — would reduce the Carver's Thread Sight capacity by a measurable but survivable percentage. Perhaps five to eight percent per intervention.*
"And repeated applications."
*Cumulative. A Carver who performs structural reinforcement on five nodes has lost thirty to forty percent of their Thread Sight capacity. On ten nodes, the capacity is reduced below functional levels. The Carver loses Thread Sight entirely.* She paused. *Beyond that, continued application draws on the biological thread-patterns that organize neural function itself. Not Thread Sight — cognition. Memory. Sensory processing. Motor function. The Carver's brain loses its organizing structure.*
The clinical translation was straightforward. Perform the technique a few times and your power fades. Keep going and you go blind to threads. Keep going past that and you lose your mind.
"In the three dimensions where Carvers developed this technique," he said. "What happened to them?"
*In the first, the Carvers used the technique extensively during a severe Gradient incursion. Seven Carvers participated. All seven lost Thread Sight within months. Three continued beyond that point. Two of those three suffered permanent cognitive degradation. The Gradient was repelled. The dimension survived. The cost was borne by seven people who chose to bear it.* She paused. *In the second dimension, the Weavers intervened before the technique was widely adopted. Records were removed. The technique was lost within a generation. In the third, the Carvers refused to stop using it despite Weaver objections. The Weavers withdrew from that partnership.*
"You left because they wouldn't stop helping."
*We left because the cost was falling on them, not on us. Because our infrastructure was being repaired with human cognitive material. Because the Weavers were benefiting from a sacrifice they were not making and could not reciprocate.* Her threads carried the frequency he read as conviction — not the defensive kind but the settled variety. A position arrived at through consideration and maintained through principle. *We do not use methods where the cost falls disproportionately on our partners. This is not policy. It is ethics.*

He was quiet for a long time.
The bait node stood half-built in the clearing. Weaver architecture and granite and forest and the Loom's substrate running through all of it. The Reality Sight showed him everything — the thread-patterns of the trees, the molecular organization of the soil, the distant glow of the city's active nodes twenty kilometers south. All of it structured. All of it organized by the same principle that organized his neural architecture and Nira Sol's cognitive threads and the bait they were building to feed a mindless process of consumption.
"You removed the records from our archives to prevent us from discovering the technique and using it."
*Yes.*
"And you didn't tell me about it when you described the Gradient response options."
*No.* She did not add justification. She acknowledged the omission and let it stand.
He could have been angry. The information gap had been deliberate — a choice made by the Weavers, for what they considered ethical reasons, that limited humanity's options in the face of a threat. Korvane would have called it manipulation. He would have been partially right.
But Voss had spent two years working with the Weavers. He had read Nira Sol's thread-architecture closely enough to build a model of her decision-making process. She was not hiding this to gain advantage. She was hiding it because she believed the technique should not be used, and she believed that revealing it would lead to its use, and she believed that the use would cost humans more than the benefit justified.
She was wrong about whether to reveal it. She was not wrong about the cost.
"I understand your reasoning," he said. "I disagree with the decision to withhold. But I understand why you made it."
*I expected you would disagree. Your species makes different calculations about acceptable cost than we do.*
"Yes. We tend to prefer making the choice ourselves."
*That is exactly what concerns me.*
He looked at his right hand.
The two cold fingers. Index and middle. Pale at the nail beds. Three degrees below the temperature of the surrounding tissue. A thread-density deficit localized to the contact area — the exact mechanism Nira Sol had just described. A zone where the Gradient's residue had created a depletion, and the Loom's organizing radiation was absent.
Except the depletion should not have been localized. The residue he had touched at the Greywater node was ambient — dispersed through the space, not concentrated enough to create a focal point of drainage. The contact should have been like dipping a finger in cold water. Uncomfortable. Brief. Not lasting.
Unless something else had happened at the contact point. Unless his own thread-energy — the biological resonance that made his neural architecture compatible with the Loom's substrate — had flowed into the depleted zone and stayed there. Not drawn out by the Gradient. Drawn out by the gradient's absence. The deficit pulling on his compatible energy the way a vacuum pulled on air.
The cold in his fingers was not damage from the Gradient.
It was the aftermath of structural reinforcement. Involuntary. Automatic. His thread-energy flowing into the depleted space because his architecture was compatible and the gradient demanded it. He had not chosen to do it. His biology had done it for him — the resonance responding to the absence the way a tuning fork responded to a matching frequency.
He had been performing structural reinforcement without knowing it. For four seconds. At the Greywater node. And the cost was already written in the temperature differential of two fingers.
Nira Sol was watching him. Her thread-architecture was in the transparent configuration — she could read his signature as clearly as he could read hers. She saw where he was looking. She saw the cold fingers. And she was a being of sufficient intelligence and observational capacity to connect the same dots he had just connected.
She said nothing. The absence was its own communication — the silence of someone who had just watched a conclusion arrive and was giving it room.
He flexed the cold fingers. They moved. They worked. Five to eight percent per node, she had said. Two fingers' worth of substrate restoration was nowhere near a full node. The cost was fractional. Measurable but not debilitating.
He put his hand in his pocket and turned back to the bait node.
"Let's finish the construction," he said.
