Chapter 224: Sedation and Alignment

The moment the elevator doors slid shut, the sensation of weightlessness came over him again. Lin Chen stared at the jumping floor numbers, his fingers tapping twice, unconsciously, against the seam of his trousers. It was not anxiety; it was muscle memory. In his mind he ran through the route once: turn right in the first-floor lobby, cross the inpatient department corridor, take Elevator 3 to the twelfth floor, then turn left to the third ward. The whole trip would take no more than four minutes.

The smell of disinfectant in the corridor was stronger than usual, mixed with a faint trace of iodine and the dampness of old bedding. The call bell at the nurses' station was still ringing. He quickened his steps. When he pushed the door open, Xiaoman had already quieted down. His eyelids were half lowered, and his breathing had been pressed deep by the sedative. The attending doctor was adjusting the flow rate on the infusion pump. Seeing Lin Chen come in, he nodded.

"A sudden myoclonic episode, lasting twelve seconds. The EEG monitoring showed abnormal discharges spreading from the temporal lobe toward the parietal lobe." The doctor's tone was steady, as if reading from a standard report. "We added sodium valproate and diazepam. We'll observe him for today. If another episode occurs this afternoon, we'll have to consider adjusting the plan."

Lin Chen walked to the bedside and tucked the corner of the quilt around Xiaoman. His younger brother's fingers were still slightly curled. The sketchbook had fallen near the foot of the bed. Lin Chen picked it up and turned to the newest page. The pencil lines were heavier than yesterday's; the outlines of the stars were a little distorted. He put the sketchbook back into the drawer and pulled the zipper closed.

"What about the cost?" he asked.

"The sedative and the urgent EEG come to about twelve hundred. If we adjust the medication this afternoon, it will add roughly three hundred a day." The doctor handed him an informed consent form. "A family member needs to sign here. Also, I asked the Provincial Hospital for you. One special-access slot has opened this week, but the deposit is twenty thousand. The appointment is for the morning after tomorrow."

Lin Chen took the pen. The tip paused on the paper for one second. Twenty thousand. He took out his phone and opened his banking app. The balance read: 847.32. The final payment for the demo project had not come in yet. Su Man's letter of intent had not been signed. The numbers aligned automatically in his mind, like assigning variables in code. He signed his name, his handwriting steady.

"I understand. I'll raise the deposit tonight."

Nine ten. Lin Chen sat on the plastic chair outside the ward and opened his laptop. The screen lit up; GitLab's commit history was still paused at last night. He switched to the terminal and ran the memory probe script once. Logs scrolled by: GC recovery normal, the circuit-break threshold for cyclic dependencies effective. He took screenshots, packaged them into a PDF, and renamed it DICOM_Parser_v3_Logs.pdf.

His phone vibrated. Su Man sent a location: "Across from the hospital, second floor of Luckin Coffee. Bring your laptop."

He closed the computer and went to the nurses' station to explain the care arrangements. The aide was one of the hospital's partners and charged by the hour; Lin Chen prepaid four hours. The aide nodded and pushed a wheelchair into the ward. Lin Chen turned and went downstairs. The early-winter wind cut through the connecting corridor, puffing up the hem of his coat. He lowered his eyes to his left foot. The pain was still there, but it had become background noise.

There were not many people on the second floor of Luckin Coffee. Su Man sat by the window, with three devices spread out in front of her: a slim laptop, a tablet, and a prototype portable EEG recorder. She wore a dark-gray turtleneck, her hair casually pinned up, faint shadows under her eyes.

"Sit." She skipped the greetings and pushed the tablet toward him. "The metadata parsing for DICOM headers—I looked at your probe logs from last night. Changing recursion to iteration was the right call, but your handling of edge nodes is too conservative. The fault tolerance for medical imaging cannot be set by internet standards. Miss one sequence number, and the entire lesion reconstruction shifts."

Lin Chen sat down and opened his laptop. He pulled up the dependency diagram he had drawn the night before and pointed to one module. "It's conservative because the raw data contains a lot of nonstandard private fields from different vendors. If we force parsing, memory will overflow. I added whitelist filtering and only extract standard fields. For the nonstandard parts, I left hooks. We can adapt them in phase two."

Su Man stared at the screen for a few seconds, her fingers sliding across the touchpad. "Hooks are fine. But the demo version must run through the complete workflow. What the client wants is a visualized result, not an architecture brief." She paused. "With your plan, how much performance loss are we talking about?"

"Within 12%. If we add real-time topology, it goes to 18%. But I implemented preloading, so first-screen rendering can be compressed to two seconds."

"Enough." Su Man closed the tablet and leaned forward slightly. "Lin Chen, let's not talk in abstractions. If this project runs, the neurology department at City Hospital will purchase three sets. The license fee is eighty thousand per set, and we take forty percent. You're responsible for the underlying parsing and performance optimization. I'm responsible for the algorithm layer and clinical coordination. Equity will be divided by technical contribution: 35% for you, 45% for me, and the remaining 20% reserved for later financing."

Lin Chen did not answer immediately. He opened his mistake notebook to the newest page. The words from last night were still there: "Thresholds are not for breaking through; they are for holding the line." He picked up his pen and added a line beneath it: "35% is the floor. Delivery standards go into the agreement. Payment milestones bind to clinical acceptance. No valuation-adjustment bet."

"Fine," he said, looking up. "But the agreement needs one more clause: the intellectual property for the underlying code belongs jointly to us. The client only gets usage rights. Also, payment is split into three stages, with the final payment after clinical acceptance. If the client delays, we have the right to suspend authorization."

Su Man looked at him. The corner of her mouth moved slightly, as if she were smiling, or as if she were confirming something. "You're much clearer-headed than last time. All right. I'll have legal draft it this afternoon. We sign tomorrow."

Eleven forty. The meeting ended. Lin Chen packed the laptop into his backpack. When he stood, his left foot missed its footing for an instant, and his knee knocked against the table leg. He made no sound, only rubbed it. Su Man had already gathered her things. Before leaving, she handed him a USB drive. "The prototype's driver and the test dataset. Run it once tonight. If there are any problems, contact me anytime."

He took the USB drive. The metal shell was cold.

Outside the café, the sunlight was harsh. He stood by the roadside, waiting for the light to change. His phone vibrated in his pocket. It was not Su Man. It was the hospital landline.

He answered.

"Mr. Lin." The nurse's voice was calmer than it had been in the morning. "Xiaoman is awake and hasn't had another episode. The doctor wants you to come back. There's a referral form that needs a family member's confirmation and signature. Also..." The nurse paused. "Provincial Hospital just called. The special-access slot has been moved up. Tomorrow at nine in the morning. But the deposit must be transferred to the designated account before the end of work today, or the slot will roll over to the next patient."

Lin Chen looked at the traffic light across the road. The numbers were counting down: 58, 57, 56...

Twenty thousand. The final payment had not been settled. Su Man's agreement would not be signed until tomorrow. The demo environment had to be locked tonight.

He took a deep breath. Cold air poured into his lungs, carrying the particular dust smell of the city.

"I understand," he said. "I'll come over this afternoon to handle the paperwork."

He hung up. He opened the mistake notebook and wrote on a new page:

"Article 224: Variables can mutate; anchors cannot move. Technical debt must be paid, and family must be saved. There is no perfect parallelism, only priority sorting. Next steps: return to the hospital this afternoon to sign the referral form; contact Old Zhao to push the demo final payment. Tonight, run Su Man's test dataset through. The twenty-thousand deposit must arrive tonight."

The pen tip paused. He raised his head and looked at the traffic flowing through the intersection. A bus rolled slowly past, carrying an advertisement for a technology company on its side: "Let data see life."

He closed the notebook and stepped into the crowd. His left foot landed; the pain was still there, but his pace did not falter. He knew that over the next twenty-four hours, there could be no more buffer. The threshold had been compressed to its limit. The next step could only be execution.
