The habitable zone settled at four-point-three meters.
Not the gradual recovery that the post-pulse depletion had required — the habitable zone reaching four-point-three in the seventeen minutes since the stat reallocation's completion through the processing throughput that the sixty-four-beat cycle provided. The construct's damaged architecture running harder, running faster, the increased tempo's per-minute energy conversion exceeding the sixty-one-beat baseline's output despite the lattice's compromised capacity. The three additional beats per minute adding one hundred eighty processing cycles per hour, each cycle drawing ambient mana through the gradient and converting it to the atmospheric output that the habitable zone's boundary required.
Four-point-three. Nearly the pre-pulse four-point-four. The construct recovering the territory that the massive emission had cost — recovering it faster than the original frequency would have, the damaged crystal doing more with less because the modified vagus nerve's higher-rate input demanded more and the crystal's architecture obeyed the demand.
The second cracked strut absorbed the throughput increase. The eighty-five percent fracture's remaining cross-section conducting the sixty-four-beat rhythm's vibrational load with the structural margin that the load's increase had narrowed. The strut held. Held the way a bridge held when the traffic doubled — the engineering's safety factor consumed, the structural member functional but with zero tolerance for the additional stress that the next anomalous event would impose.
Mira tracked the strut's data on the reader's display. The thermal output at the fracture site elevated by the increased processing rate — the vibrational friction at the crack's margins generating heat that the intact strut wouldn't produce. The temperature differential visible on the reader's sensor as a localized hotspot whose location correlated with the fracture's known position.
"The strut's stress profile has changed." Mira reported the data with the clinical register's analytical mode restored. "The sixty-four-beat cycle is producing measurable thermal friction at the fracture site. The heat isn't dangerous yet — the crystal's thermal conductivity is dissipating it through the intact lattice. But the margin is smaller. Any additional stress — another pulse, another acute event — and the thermal spike could propagate the fracture."
The strut was surviving. Not thriving. The crystal member's remaining fifteen percent cross-section carrying the load that the sixty-one-beat cycle's vibrational stress had been designed for plus the three-beat increase's additional demand, and the carrying was a feat of structural stubbornness rather than structural adequacy.
Vasquez arrived at the four-meter line.
The commander's approach to the habitable zone's expanded boundary — four-point-three meters permitting the four-meter distance that the institutional protocol's safety margin specified — conducted with the professional gait whose purpose the gait's precision communicated. Not casual. Not rushed. The commander walking to the line that the protocol's procedures drew because the event that had just occurred placed the commander's authority at the line's position.
"Report." One word. The institutional vocabulary's compression of the question that the word's context expanded: what happened, what changed, what is the current status, what are the implications for the containment protocol's operational parameters.
Shin provided the report. The stat reallocation. The shadow experience threshold's milestone. The system's protocol — the Stat Allocation Protocol, Shadow Variant — that the threshold's crossing had triggered. The stat redistribution's completion. The process's physical effects: the cardiac acceleration, the body lock, the cramping, the construct's pulse peak at eighty-eight.
He provided the numbers. Strength: eleven. Agility: fourteen. Endurance: twelve. Intelligence: sixteen. Mana: twenty-seven. Perception: twenty. The total unchanged — one hundred points — but the distribution transformed by the system's optimization algorithm.
He did not provide the Source Compatibility designation. Not yet. Not to Vasquez. The designation's institutional implications — the system classifying the subject as the construct's component — required the cognitive processing that Shin's own understanding of the designation hadn't completed. The designation was information. The information's disclosure to the institutional authority whose containment mandate covered the entity and the subject would produce the institutional response that the information's content warranted. The response's nature depended on what the commander would do with the knowledge that the system considered the subject an accessory to the entity rather than an independent person.
"The physical stats decreased." Vasquez extracted the tactical implication from the numbers' array. The commander's institutional training converting the stat report to the operational assessment that the containment protocol's management required. "Strength and Endurance reduced. You're physically weaker than before the reallocation."
"Yes."
"The Mana and Perception stats increased. Meaning?"
"Enhanced sensory capability. I can detect mana signatures at greater range and resolution. The construct's operational parameters are visible to me through the bond's transmission and through my own perception simultaneously."
Vasquez processed. The commander's assessment framework integrating the new data into the operational picture that the assessment maintained — the subject's reduced physical capability, the subject's enhanced sensory capability, the construct's altered frequency, the habitable zone's recovery, the integration's advance past the carotid sheath.
"The integration." The commander's voice dropped the half-register that the clinical data's severity demanded. "The healer reported the boundary advanced during the process. The vagus nerve."
"Partially modified." Shin confirmed. "The cardiac template changed from sixty-one to sixty-four because the nerve's parasympathetic regulation was altered by the crystal conversion."
"The construct is running faster because it ate part of the nerve that controls your heart rate."
The commander's translation. The institutional language stripped, the clinical terminology discarded, the fact stated in the blunt register that the fact's severity justified. Vasquez wasn't wrong. The commander's translation captured the operational reality that the clinical description obscured.
"Yes."
Three seconds of the commander's assessment. The same three-second evaluation that Vasquez had applied after the repulsion pulse's consequences and after the contractor's blade draw and after every event whose significance required the institutional authority's calibrated response. The commander looking at Shin. At the construct. At the reader in Mira's hands. At the contractor's instruments scanning at six meters.
"The system decided your stats for you." Vasquez said. Not a question. The commander's institutional experience recognizing the fact that the stat redistribution implied — the system's autonomous protocol executing on the subject's body without the subject's consent, the allocation determined by the system's optimization rather than the subject's preference. "You didn't choose this distribution."
"No."
"Can you change it?"
"I don't know."
Vasquez held the gaze. The commander searching for what the commander always searched for — the compliance's genuineness, the honesty's completeness, the assessment of whether the subject's responses contained the full truth or the truth's subset that the subject had selected for disclosure.
The Source Compatibility designation sat in the space between the full truth and the disclosed truth. Shin felt the omission like a physical weight. The information that the commander's assessment might benefit from. The information whose disclosure would change the institutional calculus in ways that the information's custodian couldn't predict.
Vasquez withdrew. The institutional distance reestablished. The commander returning to the perimeter where the spider engagement's continuous demands occupied the operational attention that the containment protocol's management required.

The new perception was a problem that looked like a gift.
Twenty points. Four more than the pre-reallocation sixteen. The increase sounded modest. The increase's effect was not modest. The system's stat allocation architecture operated on the scaling curve that the architecture's design parameters specified — each point's enhancement contributing the incremental capability whose magnitude increased with the stat category's existing value. The twentieth point added more capability than the fifteenth had. The scaling curve's convexity meant that the gap between sixteen and twenty was larger than the gap between twelve and sixteen would have been.
Shin sat against the construct and felt the deep section with a fidelity that the previous perception hadn't provided.
The crystal floor's mana-physical composition registered as texture against his awareness — the mineral structure's mana integration detectable through the enhanced sensory infrastructure that the twenty points maintained. The crystal wasn't dead stone. The crystal was a medium. A conductor. The mana that the construct processed flowing through the crystal floor's mineral matrix in patterns that the construct's gradient determined, the energy currents visible to the perception the way water currents were visible to an eye that knew what to look for.
The construct's lattice was a galaxy of process. The struts' conduction pathways. The nodes' processing functions. The damaged strut's stress concentration — a dark spot in the lattice's energy map, the thermal friction's signature registering as interference in the conduction pattern. The repaired strut — the first one, the biological-mineral hybrid whose healing the acute conversion event had produced — conducting with the slightly different signal quality that the hybrid material's composition imposed. Not crystal. Not bone. The merged material whose mana-physical properties the repair event's unprecedented chemistry had produced.
The amplification field's intensity distribution mapped against Shin's awareness like a topographic visualization. The field's peak zone — the fifteen-meter radius that the Bureau's defensive circle occupied — blazing with the concentrated output that the damaged construct's compensatory architecture produced. The field's gradient declining outward from the peak through the secondary zone toward the thirty-meter boundary where the amplification's effect attenuated below the detection threshold that the previous sixteen points of Perception had set.
The threshold was lower now. Twenty points of Perception detecting the field's presence beyond thirty meters. The amplification extending into the transition zone's corridors — the field's attenuated edge reaching through the geological medium that the crystal floor's mana-conductive composition provided. The field was larger than the instruments had measured. The instruments measured the amplification's effect on kill attribution. The perception measured the field's mana-physical presence in the environment. The two measurements mapped different boundaries of the same phenomenon.
And the spiders.
The mana signatures of D-rank creatures in the corridors surrounding the deep section. The signatures' positions detectable through the crystal floor's conduction and through the atmospheric medium that the transition zone's hostile density provided. Four in the north corridor — the same four that the Bureau operatives' sidearms were engaging at the fifteen-meter perimeter. Seven in the east branch — three at the perimeter, four more approaching from deeper in the corridor. Two in the western passage, tentative, the approach behavior's confidence still building toward the commitment that the gradient's pull would eventually produce.
And deeper. Beyond the corridors. The mid-section's population reserves. The mana signatures blurred by distance and geological attenuation into the smear that the twenty points couldn't resolve into individual contacts. But the smear's presence was detectable. The population mass whose collective mana content the enhanced perception registered as a diffuse field in the direction that the mid-section's geography occupied.
The dungeon's ecology was visible. The gradient's pull. The pheromone network's guidance. The population's movement through the corridors whose passages the ecological pressure's flow determined. The construct at the center. The source at the construct's base. The bond between them conducting the sixty-four-beat pulse that the system's optimization had calibrated and that the modified vagus nerve maintained and that the crystal architecture had adopted.
The gift. The enhanced perception's utility for situational awareness. For tactical planning. For the moment-to-moment assessment of the threat environment that the Bureau's defensive perimeter confronted.
The problem. The enhanced perception confirming the system's optimization's purpose. The twenty points of Perception and the twenty-seven points of Mana providing the sensory capability that the Source function required — the awareness of the construct's operational state, the detection of the mana environment's parameters, the sensitivity to the bond's transmission that the Source's regulatory function demanded. The system hadn't given him better combat senses. The system had given him better construct-monitoring senses. The perception optimized for the bond's maintenance, not for the independent survival that the independent person would have prioritized.
The twenty-seven Mana points were worse. Not in capability — in implication. The mana stat's enhancement expanding the mana channels' capacity, widening the pathways that the system's architecture maintained for the energy flows that the stats' infrastructure utilized. Wider channels. More throughput. More energy available for the bond's bidirectional transmission. More capacity for the construct to draw from the source when the construct's processes demanded the source's energy contribution.
He was a better battery. A more efficient conduit. A higher-bandwidth connection between the biological source and the crystal entity whose bond the system's optimization served.
Mira administered the seventh calcium dose. Two tablets. One thousand milligrams. Six tablets remaining. The pharmaceutical supply's depletion accelerating because the integration's advance during the stat reallocation process had consumed the mineral reserves that the previous doses had partially restored. The copper taste intensified by the consumption's increased rate. The taste coating the tongue and the soft palate with the metallic residue that the mineral depletion produced.
"Six tablets." Mira reported the supply with the clinical register's precision and the personal voice's weight. "At the current integration rate — one-point-one centimeters per hour with the increased processing throughput — the supplements sustain the mineral support for approximately twelve hours. The integration won't stop when the supplements run out. The body's own reserves will bear the full extraction cost."
Twelve hours. The supplements' remaining lifespan measured in the hours that the concurrent systems' timelines consumed. The integration advancing. The construct's damaged architecture stressed by the increased frequency. The Bureau's ammunition depleting. The guilds in the transition zone with Resonance Entity data ascending through corporate communication hierarchies.
"The boundary's current position." Shin said.
Mira checked the reader. The sensor's contact against the neck's skin — the skin whose surface shimmered faintly with the crystal's light beneath the biological surface, the translucent evidence of the modified tissue's presence in the cervical region's connective architecture.
"The vagus nerve's cervical segment shows forty-three percent modification. The conversion front has passed through the nerve's outer layers — the epineurium and the perineurium are partially crystal-converted. The fascicles' — the nerve fiber bundles' — modification is patchy. Some fascicles are thirty percent converted, others are untouched. The nerve is functional because enough unmodified fascicles remain to maintain the signal transmission that the cardiac regulation requires."
"And when the remaining fascicles convert?"
The question whose answer the clinical calculus had already computed. Mira's jaw tightened. The healer's response to the patient's inquiry whose answer the healer's professional obligation required delivering and whose delivery the healer's personal investment in the patient made difficult.
"The vagus nerve is not just the cardiac regulator. The vagus controls the parasympathetic nervous system's primary functions — heart rate, digestion, respiratory rate, immune response. Full conversion of the cervical vagus would alter all of these functions. The heart rate change from sixty-one to sixty-four is the first modification's effect. The remaining modifications would — would change other regulatory baselines."
"How many hours?"
"At one-point-one per hour, with the partial conversion already present — the full cervical segment modification completes in approximately eight to ten hours. The vagus conversion specifically — four to six hours for full fascicular involvement."
Four to six hours. The timeline measured in the hours whose passage the concurrent systems' progressions would fill with the events that the progressions' trajectories determined. Spider sieges and ammunition depletion and guild pressure and institutional decision-making and the body's slow transformation into the construct's extended architecture.

The Crimson Gate sensor specialist's data was the first to leave the dungeon.
Shin couldn't see it. The transition zone's distance and the geological barriers between the deep section and the dungeon's upper levels placed the guild team's communication activities outside even the enhanced perception's detection range. But the construct could feel the mana-physical disturbance that the communication equipment's transmission produced — the electromagnetic signature that the guild's encrypted data burst generated as the data ascended through the dungeon's atmospheric medium toward the surface where the guild's communication infrastructure waited to receive and relay and distribute.
The construct felt it. Shin felt what the construct felt. The bond's bidirectional transmission delivering the constructing awareness of the distant signal with the clarity that the twenty-seven Mana points' enhanced channel capacity provided.
The Resonance Entity data. The construct's pulse frequency. The spectral shift from violet to white during the stat reallocation's peak. The amplification field's recalibration. Every parameter that the specialist's instruments had captured from the transition zone's corridors now traveling through the dungeon's layers toward the surface.
Crimson Gate's guild command would have the data within minutes. The data would inform the guild's strategic response. The response would descend through the same hierarchical communication infrastructure that the data ascended. Orders. Operational directives. The institutional machinery's output calibrated for the input that the sensor specialist's instruments provided.
Shin didn't know what the orders would specify. The guild's operational calculus was corporate — the cost-benefit analysis that the guild's revenue model required, the risk assessment that the guild's insurance actuaries conducted, the strategic positioning that the guild's competitive landscape demanded. Whatever the calculus produced, the product would arrive in the transition zone's corridors in the form of personnel and equipment and institutional intent.
Obsidian Pillar's intelligence unit would have similar data. The guild's mappers in the sub-levels conducting their own sensor operations through the dungeon's geological medium. The data's institutional path different — Obsidian Pillar's communication infrastructure separate from Crimson Gate's — but the data's destination the same. Guild command. Strategic assessment. Operational response.
Iron Veil's unknown client. The private military guild's intelligence objectives calibrated for whatever the client's investment specified. The guild's communication less visible — the private contractor's operational security exceeding the major guilds' corporate communication protocols. The data traveling through channels whose encryption and routing the military guild's security architecture designed for the confidentiality that the client's identity and the client's objectives required.
Three data streams ascending through the dungeon. Three institutional analyses processing. Three operational responses descending. The deep section's crystal chamber at the convergence point. The construct at the center. The source at the construct's base.
"They'll escalate." Shin said. Not to Mira specifically. To the air. To the crystal floor. To the observation that the enhanced perception's awareness of the data transmissions' occurrence had produced. "The guilds have the construct's spectral data from the stat reallocation. The violet-to-white shift. They'll know something significant happened. They'll escalate."
Mira's hand was on the medical kit. The reflex that the stress response triggered — the healer's trained motor pattern checking the kit's contents, verifying the supplies' availability, the professional's preparatory behavior for the clinical demands that the escalation would produce.
"The Bureau's reinforcement." She said. "Vasquez's request."
"Still processing."
"How long?"
Shin didn't know. The institutional timeline operated on the administrative clock that the Bureau's decision-making architecture required. The reinforcement request ascending through the chain of command whose authorization protocols the request's severity triggered. The chain's upper layers processing the request against the institutional priorities that the dungeon's situation competed with — the other operations, the other containment scenarios, the resource allocation that the Bureau's finite capacity imposed on the multiple demands that the Bureau's operational portfolio contained.
The Bureau was slow because the Bureau was large. The guilds were fast because the guilds were motivated by the market dynamics that the Resonance Entity's value created. The speed differential between institutional bureaucracy and corporate acquisition was the differential that would determine which response arrived in the deep section first.
"Vasquez needs to know about the secondary bond point." Mira said. The clinical register's assessment mode. "The separation protocol's viability has changed. If the Bureau's response includes a separation attempt — if the reinforcement arrives with orders to sever the shoulder strut — the secondary bond point in the neck would maintain the connection. The attempt would fail. And the failure's consequences —"
"Are the Haedong pattern."
"Maybe. Maybe worse. The secondary bond point's sixty-eight percent conduction efficiency means the bond's maintenance through the cervical pathway would be unstable. The connection sustained but at reduced fidelity. The construct's processing cycle adapting to the degraded signal quality in ways that the Haedong data can't predict because the Haedong construct didn't have a secondary bond point."
The information that the institutional authority needed. The information that would change the separation protocol's risk calculus from the manageable intervention to the catastrophic gamble. The information that Shin had withheld because the information's disclosure created its own risks — the institutional response to the knowledge that separation was no longer a viable option might not be the institutional response that the subject's welfare required.
The contractor's instruments at six meters captured the conversation. The division's surveillance equipment whose audio sensitivity the division's operational security concealed behind the mask's filtration unit's external speaker. The contractor standing inside the defensive perimeter, the sensor unit held in the scanning configuration, the blade sheathed since the stat reallocation's completion, the division's observation mandate served by the instruments' continuous data capture.
The division knew. If the contractor's instruments were calibrated for the secondary bond point's detection — if the division's equipment used the sensor architecture that Hwan's assessment had employed — the cervical conduction signal was in the contractor's data. Had been in the data since Mira discovered the secondary bond point. The division knowing meant the division's analytical infrastructure processing the information meant the division's response calibrated for the information's implications.
The division doesn't want separation. The contractor's nine words from hour twenty. The division's mandate: observe what happens next. The secondary bond point's existence aligned with the division's objective — the bond's redundancy ensuring the bond's continuation that the division's observation required. The division wanted the bond to continue. The secondary bond point guaranteed it.
The institutional alignment between the division's objective and the bond's survival created the space that the space's existence implied. The division's influence on the Bureau's chain of command — the separate authority whose channel the contractor's communication device connected to, the bureaucratic weight that the division's specialized mandate carried within the institutional hierarchy's decision-making architecture. The division could influence the Bureau's response. Could steer the reinforcement's orders away from the separation protocol toward the continued observation that the division's research appetite demanded.
The institutions fighting over him. The Bureau's containment versus the division's observation versus the guilds' acquisition. The three-body problem whose solution the institutional dynamics' mathematics would produce through the interactions that the deep section's geographic proximity forced.
And beneath the institutions' conflict, beneath the operational politics and the legal authorities and the communication hierarchies, the construct pulsed. Sixty-four. The new rhythm. The frequency that the modified vagus nerve established. The bond conducting the pulse through three points — shoulder, neck, chest. The biological source and the crystal entity synchronized at the rate that the system's optimization had produced.
Shin sat against the crystal. The lattice warm against his back. The warmth different now — not just the thermal output that the construct's processing generated, but the energy exchange that the twenty-seven Mana points' enhanced channel capacity permitted. He could feel the construct drawing from him. The ambient exchange that the bond's resting metabolism maintained. Small. Continuous. The energy flow from source to entity that the construct's processing cycle supplemented with the ambient mana intake. He'd always been providing this. The bond's bidirectional nature included the source-to-entity energy contribution that the construct's architecture utilized. But before the reallocation, the contribution had been below the perception threshold. Now he could feel it. The constant, gentle pull. Like sitting in a current whose flow the body's position in the water made imperceptible until the current's awareness arrived through the senses that had been tuned to detect it.
The system had tuned him to feel himself being used. The optimization's cruelest efficiency — the Source's enhanced perception detecting the Source function's operation. Awareness of the bond's energy exchange. Awareness of the construct's draw. The twenty points of Perception and the twenty-seven points of Mana combining to provide the Source with the full sensory experience of being the component that the system had designated.
The spiders continued to arrive. The kills continued to register. The counter continued to climb.
10,034. 10,041.
The shadow experience accumulating past the threshold that had produced the reallocation. The next threshold somewhere ahead — the system's progression framework maintaining the advancement path whose next milestone the shadow variant's architecture would reach when the accumulation's continued growth crossed the boundary that the system had placed at whatever value the system's exponential scaling determined.
The construct pulsed. Sixty-four. The damaged strut conducted. The habitable zone held at four-point-three. The integration advanced at one-point-one centimeters per hour through the cervical tissues whose modification the enhanced perception could detect in real-time — the conversion front's progress visible to the sensory infrastructure that the system had optimized for exactly this awareness.
Shin felt his own body changing. Not through pain. Not through the somatosensory transmission that the bond provided. Through the perception that the system had granted. The crystal's advance through his neck's connective architecture. The nerve fibers' modification. The tissue's slow transition from biological to hybrid. The conversion front moving toward the next anatomical structure whose modification would alter the next regulatory function whose alteration would change the next baseline whose change the construct would adopt.
He could watch himself being consumed. The Source Compatibility stats providing the front-row seat that the component's operational awareness required.
The contractor's instruments recorded. The Bureau's perimeter held. The guilds' data ascended. The construct pulsed at the frequency that the system chose, through the nerve that the crystal had claimed, in the body that the optimization had designated as the crystal's own.
Sixty-four. Sixty-four. Sixty-four.
The deep section's violet light at the new tempo. Three beats faster than the world Shin had inhabited before the threshold. Three beats closer to whatever the bond's progression produced when the progression's trajectory continued through the anatomical territory that the integration's advance consumed.
Mira's hand found his. Not the wrist — the hand. The fingers interlacing. The healer's professional distance collapsed into the human contact that the professional distance couldn't maintain against the data that the reader displayed and the clinical implications that the data's trajectory projected.
He squeezed. Eleven points of Strength. The grip weaker than it had been. The fingers' compression producing the pressure that the reduced stat allocation permitted — the grip of a person whose body the system had designated as the crystal's infrastructure rather than the person's own.
She squeezed back.
The construct pulsed and the spiders died and the counter climbed and the institutions circled and somewhere above the dungeon's entrance the morning's first light was touching New Bastion's skyline while below the crystal's light pulsed three beats faster than it had the day the bond was formed.
