Latch's hands jerked off Wei Long's temples two hours and seven minutes into the reading.
The elder didn't speak. His fingers curled inward, the way they did when biological data contradicted his expectations. He pressed them against his own robe, wiping something that wasn't on his hands, then reached for the wall and read the junction fold's tissue for eleven seconds before turning back to Wei Long.
"The micro-lattice is growing."
"Growing." Wei Long sat up straighter. He'd been leaning against the wall during the reading, passive, the Crown's active processing disengaged while Latch's biological bond extracted data from the crystal deposits in the substrate. "Growing how? The Crown isn't active."
"The Crown doesn't need to be active. The micro-lattice's recording function operates on embedded instructions. It records data that passes through the substrate's processing layer. My bond is passing through the substrate's processing layer." Latch's voice was stripped to its clinical minimum. No excess words. "The recording function is treating my biological bond's contact as input data. Each minute of the reading generates substrate activity that the artifact interprets as processing output. The micro-lattice is recording the reading itself."
"How much growth?"
"Approximately point-two percent per hour. At four hours of total reading time, the micro-lattice would grow by approximately point-eight percent."
Wei Long's hands went to the wall. The fold's heartbeat against his palms. The Crown at forty percent capacity, the micro-lattice at three-point-nine percent before the reading began. Two hours and seven minutes had already added approximately point-four percent. The current micro-lattice was at four-point-three percent. Effective capacity at forty percent: thirty-five-point-seven.
"Why didn't you detect it earlier?"
"The growth rate during the reading is slower than during active Crown processing. During an integration session, the artifact grows at point-one-five percent per session because the Crown's processing output is high-intensity. My bond generates low-intensity substrate activity. The growth rate is lower per minute, but the reading is sustained for hours. The cumulative effect didn't become detectable until enough crystal had accumulated for my bond to register the dimensional change in the substrate's density." Latch's hands were steady now. Back to clinical. "I noticed because the micro-lattice's crystal deposits shifted the substrate's tissue density enough to alter the biological reading I was performing. The data I was extracting from the crystal changed quality because the crystal itself had changed during the extraction."
"The reading is corrupting itself."
"The reading is not corrupting itself. The data extraction is accurate. But the micro-lattice is growing new layers on top of the layers I'm reading, and the new layers contain recordings of my own reading activity. Like taking notes in a library where the library records every note you write and shelves it alongside the books."
"Can you read faster? Reduce the total reading time?"
"I'm reading at the maximum speed my bond allows for accurate data extraction. Faster reading produces errors. The crystallographic data in the micro-lattice is dense. Each layer contains compressed biological information that requires sequential parsing. Skipping or rushing introduces translation artifacts that would give Shen inaccurate data."
"And inaccurate data means Shen doesn't consider the deal fulfilled."
Latch didn't answer that. He didn't need to.

"How much data have you extracted?" Wei Long asked.
"Approximately fifty percent. The first two hours covered the wellspring approach, the navigation through the waste channels, the tissue damage assessment, the reinforcement process, and the first half of the reshaping operation." Latch organized the information the way he organized everything: by clinical relevance. "The remaining fifty percent includes the reshaping completion, Liu Chen's arrival, the pulse cycle impact, the return journey, and the budding structure observation."
"The budding structure is in the second half."
"The budding structure observation occurred during the return journey. It's in the final quarter of the recording."
"That's the data Shen wants most."
"That's the data Shen specified as his primary interest, yes."
Wei Long closed his eyes. The Crown's dimensional awareness continued behind the darkness, the network's topology present in his mind whether his eyes were open or closed. Thirty-four accessible nodes through the primary bridge. Seven isolated nodes behind collapsed pathways. The three-percent fold sitting in the deepest part of the network, its lattice converting its tissue to crystal at the rate of point-zero-three percent per day, the countdown running from two-point-seven toward two-point-zero.
Nine days. Minus one for the time already elapsed since the last reading. Eight days. The micro-lattice reading needed two more hours. Shen needed the budding structure data. The secondary pathways needed to open. The transit to the three-percent fold needed to happen. The clearance at that node needed to happen.
Each step consumed time that the three-percent fold didn't have and capacity that the Crown couldn't afford to lose.
"Chen Bai." Wei Long opened the relay. Two percent processing for the communicative band. He was spending capacity he didn't have on a conversation about capacity he was losing.
"Here." The analyst's pen was moving. "I've been running the projections since Latch detected the growth. The numbers are clear."
"Give them to me."
"Scenario one: stop the reading now. Micro-lattice at four-point-three percent. Effective capacity at thirty-five-point-seven. Shen receives fifty percent of the data. The budding structure information is not included. Shen's response to receiving incomplete data is — unpredictable. He may withhold the secondary pathways. He may open them partially. He may negotiate for additional payment."
"Scenario two."
"Continue the reading to completion. Micro-lattice at approximately four-point-seven percent. Effective capacity at thirty-five-point-three. Shen receives the full dataset including the budding structure observation. The secondary pathways open. You transit to the three-percent fold through Shen's routes."
"The difference between scenarios is point-four percent of effective capacity."
"Point-four percent. The difference between thirty-five-point-seven and thirty-five-point-three." Chen Bai's pen stopped. "Neither number is above the thirty-eight percent clearance threshold. Both are below the thirty-six-point-nine effective capacity we had before the reading began. The question isn't whether point-four percent matters for the junction's operations. The question is whether it matters for the three-percent fold's clearance."
"Can I clear the three-percent fold's lattice at thirty-five-point-three effective capacity?"
"Latch established that the dissolution frequency can be generated at thirty-eight percent minimum. Below that, the frequency becomes unstable. You've been operating below that minimum since the junction clearance, using the safety margin for reduced-speed dissolution." A pause. "The junction clearance worked at thirty-seven-point-five. The question is how far below thirty-eight the dissolution remains functional. We've been pushing into uncharted territory with each additional micro-lattice percentage point."
"Latch. Can the dissolution frequency function at thirty-five-point-three percent?"
The elder was already thinking. His hands pressed together in front of his chest, the biological expertise running calculations that combined dimensional physics and Crown architecture and the mathematics of crystal dissolution at reduced processing capacity.
"The dissolution frequency at thirty-five-point-three percent would be approximately eighty-three percent of the frequency's optimal strength. The junction clearance ran at approximately ninety-one percent. Each percentage point of effective capacity below thirty-eight reduces the dissolution's effectiveness by approximately three percent of optimal." He looked at Wei Long. "At eighty-three percent, the dissolution propagates slowly. The lattice dissolves. But the propagation rate is reduced enough that the clearance at a single node takes approximately forty-five minutes instead of thirty. And the dissolution's stability margin is thin. Fluctuations in the substrate's processing could drop the frequency below the minimum viable threshold during the clearance, causing the dissolution to stutter or fail mid-operation."
"Can you monitor the stability?"
"I can monitor it. I can't control it. The substrate's processing fluctuates based on the bearer's cognitive activity, the micro-lattice's recording function's variable load, and the fold's biological input through the interface. Any of those variables could cause a momentary dip that drops the dissolution frequency below viable."
"What happens if the dissolution stutters during clearance?"
"The lattice material at the stutter point re-crystallizes. The dissolution has to restart from that point. Time lost. Processing consumed. The forty-five-minute estimate becomes sixty. Or seventy. Each stutter adds time and uses effective capacity on restart energy that could have been spent on propagation."

"Shen." Wei Long turned toward the custodian. "If I give you fifty percent of the data — everything except the budding structure observation — will you open the secondary pathways?"
Shen's eyes opened. The ancient cultivator looked at Wei Long with the expression of someone who had anticipated the question and prepared the answer before the conversation began.
"No."
One word. No negotiation in it.
"The budding structure is the purpose. The tissue damage data is useful. The wellspring assessment is useful. The fold's response to the Crown's communicative-band interface is useful. But the budding structure's cellular differentiation state determines whether this network can grow. That data is not optional."
"The reading is costing the Crown capacity that I need for the clearance operations."
"The Crown's capacity is your problem. The budding data is mine." Shen's hands folded behind his back. "I have maintained this network for twenty-four centuries. I have watched nodes die. I have watched pathways collapse. I have watched the system I was entrusted with contract to less than half its original size. If the seventeen-percent fold's budding structure is genuine — if the reproductive cycle is viable — then this network might grow again. For the first time since I took my position." His voice didn't change. The ancient dialect's vowels flat and precise. "I need to know."
"Even if knowing costs the three-percent fold its chance at survival?"
"The three-percent fold is one node. The network's reproductive capacity affects every node. If I must choose between one node's survival and the network's ability to generate new nodes, the choice is clear."
"That's not your choice to make."
"Then make yours."

Wei Long sat in the corridor. The fold's heartbeat at fifty per minute. The micro-lattice at four-point-three percent and growing. Latch waiting with his hands in his robe. Shen against the wall with his eyes closed. Yue's presence in the bond carrying her assessment without pressing it, the lunar spirit who had objected to the reading before it began and was now watching the objection be validated by the mathematics.
Two hours of reading remaining. Point-four percent of additional micro-lattice growth. Effective capacity dropping from thirty-five-point-seven to thirty-five-point-three.
Or: stop now. Keep the point-four percent. Lose the secondary pathways. Lose access to the three-percent fold. Lose the node in eight days.
The math was simple. The decision wasn't.
"Continue the reading," Wei Long said.
Yue didn't react through the bond. The decision was what she'd expected. The lunar spirit who knew the bearer well enough to predict his choices didn't waste energy on surprise.
"Latch."
The elder's hands returned to Wei Long's temples. The reading resumed. The micro-lattice growing with each minute of contact, the artifact's recording function absorbing Latch's biological bond activity and converting it to crystal, the ghost protocol building new layers of recorded data on top of the intervention recording that was being extracted.
"For the record," Yue said through the bond, "you're choosing a dying node over effective capacity. Again."
"For the record, I know."
"You chose the eleven-percent fold over lattice growth. You chose the seventeen-percent fold over detection risk. You chose the micro-lattice mapping over capacity margin. You're choosing the three-percent fold over the processing power you need for the clearance that would save it." The bond carried her words without judgment. Just accounting. "Every choice spends capacity. Every choice buys a fold's life. The exchange rate keeps getting worse."
"The exchange rate was always bad. We just didn't know it at the start."
"We know it now." She was quiet for a moment. "The Crown's effective capacity is a resource that doesn't regenerate. Every point of micro-lattice growth is a permanent reduction. There's no protocol to recover lost capacity. There's no optimization that gives it back."
"I know."
"You're spending an asset that you can't replace on nodes that you might not be able to save."
"I'm spending it on nodes that are alive. The capacity is a number. The nodes are organisms."
The bond carried her silence. Not agreement. Not disagreement. The silence of a spirit who had been counting fractions for weeks and had watched the bearer spend each fraction on the same kind of choice, over and over, the numbers getting worse and the decisions staying the same.
Latch's hands on his temples. The reading continuing. The crystal growing. Two more hours.
Shen sat against the wall with his hands flat on the tissue and his eyes closed, waiting for the budding data the way he waited for everything — with the patience of someone who measured time in centuries and didn't care whether anyone approved of his price.
The fold's heartbeat continued. Fifty per minute. The organism carrying them all, housing the argument and the reading and the growth and the decline, the living architecture of a system that didn't know its bearer was spending his operational brain on its behalf, one fraction of a percent at a time.
Eight days to reach the three-percent fold. Thirty-five-point-three percent effective capacity to clear its lattice when he got there.
The numbers worked. Barely. The numbers always barely worked.
But barely was still alive.
