Chapter 241: Processes and Interfaces

At 7:50 a.m., the steps of the City First Hospital’s outpatient building still held the night’s dampness. Lin Chen stood outside the automatic doors, shifting his full weight onto his right leg while his left toe barely grazed the ground. The spasms from the night had faded into a persistent, dull ache, like a blunt needle buried deep in the inner knee, pulsing in time with his heartbeat. He drew a deep breath, taking in the mingled scents of disinfectant, aged paper, and damp earth. From his canvas bag, he pulled out the Data Desensitization Compliance Commitment Letter, which he had cross-checked word for word the previous night. The edges of the paper had curled slightly; he smoothed them flat with his palm before slipping the document into a black hardcover folder. The nine o’clock meeting was a hard deadline, but hospital administrative procedures never bowed to a developer’s timeline. He needed to arrive early to gauge the IT department’s shift schedule, track the leadership’s movements, and discern the hospital office’s true stance on third-party audits.

By 8:30 a.m., he was in the IT department corridor. The fluorescent tubes emitted a faint electrical hum, and the digital clock on the wall ticked over in red numerals. Lin Chen took a seat on a plastic bench and opened his notebook. He had broken down the mid-term briefing metrics into three tables: data integration progress, sandbox integration testing status, and compliance document routing. Each row listed a responsible party and a deadline. There were no emotional annotations, only actionable milestones. At exactly nine o’clock, the frosted glass door to the conference room was pushed open. Old Chen walked in, clutching a chipped thermos, dark circles bruising the skin beneath his eyes, a faint coffee stain marring the collar of his white coat. Two hospital office clerks followed behind him, folders in hand, their expressions strictly business.

“The Health Commission is cracking down hard.” Old Chen didn’t sit. He slid the commitment letter across the table. “The desensitization rules must be filed with the Ethics Committee. Your template is missing a signature block for the third-party audit agency. The hospital isn’t willing to assume that liability.”

Lin Chen took the document and scanned the clauses quickly. What was missing wasn’t technical logic, but procedural endorsement. He had anticipated this. He pulled another attachment from his bag and pushed it forward. “We’ve already contacted the Provincial Information Security Evaluation Center for the audit. The expedited process takes three working days, but we can issue a technical self-test report first, with a commitment to submit the officially stamped document before the gray-scale release. The hospital can approve access to the test environment in the meantime. Liability boundaries will be enforced according to Article 7 of the contract. The data stays within the intranet, never touches real fund flows, and every operation is logged and fully traceable.”

Old Chen frowned, flipping to Article 7. The clerks exchanged quiet murmurs, a pen tapping lightly against the tabletop. Lin Chen didn’t rush them. He simply unscrewed his pen cap and set it on the corner of the table. He knew the hospital wasn’t looking for technical perfection; they wanted traceable accountability. Within the system, procedural compliance always took precedence over technological advancement. He waited quietly, his breathing steady. Slanting sunlight fell through the window, illuminating the scratches on the conference table. From the corridor outside came the rhythmic, muffled sound of cart wheels rolling over terrazzo flooring.

“Sign the technical self-test commitment first.” Old Chen finally relented, picking up his pen to add a line on the back of the document. “The read-only account for the test database will be issued at two p.m. The network is physically isolated, so you’ll have to use the hospital-issued encrypted USB drive for data transfer. Do not touch the production network. If anything goes wrong, no one will be able to cover for you.”

Lin Chen nodded and packed his files away. Stepping out of the building, he found the sunlight already glaring. He leaned against the wall and sent a text to Su Man: Access approved. Pick up the USB at 2 p.m. Sandbox environment is ready. His phone vibrated almost immediately: Received. Compensation module switched to dynamic threshold. Waiting for your data. He locked the screen and let his gaze sweep across the parking lot. A black business van was parked in front of the president’s office building. The project manager from Zhiyi Cloud stepped out with two implementation staff, dressed in sharp suits and carrying custom equipment cases. They didn’t linger, heading straight for the elevator. Lin Chen looked away and turned toward the bus stop. The competition was now out in the open, but the real battle wouldn’t be fought in meeting rooms. It would be waged in the narrow gaps between code and procedure.

At 1:50 p.m., Lin Chen returned to the IT server room right on schedule. Old Chen handed him a black metal USB drive. It had an aging USB 2.0 port and a scuffed casing. “It contains the read-only connection string for the desensitized view. The password resets every twenty-four hours. Bring the old drive back tomorrow at the same time to swap it out. Don’t plug it into the wrong port—the intranet has behavior auditing.” Lin Chen took it; the metal casing was cold to the touch. Back in his temporarily rented office, he inserted the drive into an isolated machine. A terminal window lit up, the cursor blinking. He entered the connection string and pressed Enter. The database responded with a latency of roughly two hundred milliseconds, consistent with intranet characteristics. He ran the V3.0 script, and the logs began to scroll. The first batch of real transaction data flowed into the preprocessing layer: regex splitting, dictionary mapping, null-value filling. The progress bar advanced steadily. The match rate held stable at 97.4 percent. Lin Chen leaned back in his chair, and his left leg began to twitch faintly again. He pressed a hand against his knee, applying firm pressure until the pain subsided. A system notification popped up in the bottom-right corner of the screen: Security Policy Update: All external access devices must pass third-party penetration testing certification. Uncertified devices will be automatically disconnected at 18:00 this Friday. He stared at the line, his fingers hovering motionless over the keyboard.

Penetration testing certification. The lowest market quote was eight thousand yuan, with a seven-day turnaround. After deducting server rentals and Su Man’s salary, their liquid funds stood at just twelve thousand. Before Friday, they either secured the certification or the sandbox would grind to a halt. Lin Chen didn’t reply to Su Man right away. He opened a browser and searched for a list of local evaluation agencies holding Level 2 Classified Protection qualifications. He called them one by one, only to be met with fully booked schedules or quotes that blew past their budget. By the time he hung up the last call, dusk had already fallen outside. He opened his notebook and wrote on a fresh page: Friday disconnection risk. Alternatives: 1. Apply for a hospital temporary whitelist (requires signature from the vice president in charge); 2. Borrow credentials from a partner university lab (requires advisor coordination); 3. Downgrade sandbox to offline mode (impacts mid-term demo). The tip of his pen paused on the paper. He crossed out the third option. Offline mode meant real-time data validation would be impossible, stripping the gray-scale pilot of its core advantage. He picked up his phone and dialed Professor Zhou. The call connected, accompanied by the soft rustle of turning pages in the background.

“Professor, there’s a credential process issue. I need to ask for your help.” His tone was calm, skipping any preamble and cutting straight to the core. There was a two-second silence on the other end. “Email me the materials. Come to the college tomorrow at ten a.m.” Lin Chen ended the call, saved his code, and closed his laptop. His left leg still ached, but his heartbeat was steady. He knew that while technology could scrub dirty data from code, real-world procedures had to be navigated step by step. Tomorrow at ten a.m., the college office. Another hard battle awaited.
