The follow-up session was not on the program.
Han Weiwei had requested it from the organizing committee at 7:15 PM the previous evening, based on the volume of post-presentation inquiries. The committee confirmed an 11 AM slot in the third-floor hall — smaller than the plenary, fifty seats, intended for discussion format rather than lecture.
By 10:45, there were seventy people standing in the corridor outside the door.
He found a position near the back wall of the now-reconfigured hall and watched the room fill. Researchers who had been at the plenary. A few from concurrent sessions who had heard about it through the evening's conversations. Three from the national Bureau office who hadn't been present for Day One. Two foreign attendees who had driven from their respective hotels early enough to get seats.
Dr. Zhao Lianping from USTB was in the second row.
Shen Mingzhi was not in the room yet.
Han Weiwei ran the session differently than the plenary — question-led, no prepared slides, just the sensor array running its ambient data and her answering with the specificity that came from seven months of continuous study. The questions were better than yesterday's. The researchers who had spent the night thinking about the presentation came back with the sharper edges of their thinking.
"The selection criteria," said a researcher from a Chengdu cultivation institute. "You've described the mechanism types, you've described the network function. But you haven't described how the subjects were identified for deployment. What was the selection input?"
"That's an open question in my research," Han Weiwei said. "I don't have the selection algorithm. What I have is the deployment's output — the seventeen confirmed cases — and from that output I can infer that the criteria were consistent across geography and culture. The selection identified something that was portable across very different individual contexts."
"Latent cultivation potential," the Chengdu researcher said.
"That's the most parsimonious explanation," she said. "But the distribution also shows over-representation in specific demographic categories — zero-assessment individuals who had substantial prior academic or professional preparation in fields adjacent to the ability types they were subsequently assigned. The selection may have incorporated both potential and preparation."
He had not told her this. She had derived it from her own data.
He noted the slight recalibration this produced in his assessment of how far her research had independently progressed. Further than he'd realized.
Zhao Lianping raised her hand. "The Concurrent Observer paper. You said yesterday that anyone with relevant information about the author should contact you. Has anyone?"
"I've received two messages since yesterday afternoon," Han Weiwei said. "I haven't had time to assess them yet." She paused. "If you have something specific—"
"Not exactly," Zhao Lianping said. "But I've been working on the three-type coordination model independently for three years. In a very different context — my lab studies probability field interaction in spatial manipulation research. We published a paper two years ago that, I now realize, was working toward the same theoretical architecture from the opposite direction." She looked at the sensor array. "I'd like to propose a formal research collaboration."
The room registered this. Two labs, two data sets, one architecture. The kind of convergence that happened when a theoretical framework was correct — the empirical evidence showed up independently from multiple directions.
Han Weiwei said: "I'll be in touch next week."

The session ran ninety minutes. At its close, three separate researchers asked about the probability of publishing the full data set in a peer-reviewed format and what journal she was targeting. She named the National Journal of Awakened Ability Studies, which had the highest impact factor in the field and a review process that typically ran eight to twelve weeks.
The corridor outside was a research conference at its most energized — the specific quality that came when a field had just seen a result that changed its shape.
Shen Mingzhi appeared at noon, when the corridor had thinned. He found Chen first.
"She's more complete than I expected," he said.
"Her research has been running for two years," Chen said. "The study period with the local subjects is seven months. The prior groundwork is longer."
"She's going to publish before she has the full global picture."
"Yes," he said. "That's intentional. The city-local findings are solid. The global architecture's complete picture is the next phase. She knows the difference."
Shen Mingzhi was quiet for a moment. "May I speak with her directly?"
He looked at the man.
The probability field's assessment: Shen was not a threat. His interest was academic and genuine. But introducing Shen to Han Weiwei — the two people who between them held the most external knowledge of the deployment's existence — required a decision about what that introduction enabled and what it accelerated.
"Yes," he said. "I'll be present."
---
The three of them found a quiet corner of the ground-floor atrium at 12:30. Han Weiwei with her presentation notes. Shen Mingzhi with the studied calm of a man who had spent six years building to a conversation he hadn't been certain he'd have. Chen between them, saying less than either.
Shen introduced himself. Said his division's focus. Mentioned the registry.
Han Weiwei's expression through this: professional attention, the specific quality she had when data was landing in a format she could use. She did not look at Chen.
"You've been tracking the deployment independently for six years," she said.
"Since the Concurrent Observer paper appeared," Shen said. "I recognized the theoretical framework as Ren Jiuyuan's work immediately. I spent six years looking for his fingerprints in the awakened ability research landscape." He paused. "Your study is the first I've found."
"You said you were his advisor," she said. "What was his research focus before the government appointment?"
Shen told her. The stochastic optimization work, the potential-distribution modeling, the Science Ministry division. Han Weiwei listened with the pen in her hand, not taking notes but holding it the way she did when she was encoding information she intended to write later.
When Shen finished, she said: "The deployment was prepared before the Awakening Event. That means someone was able to forecast the event with enough precision to design the response mechanism in advance." She looked at Chen for the first time in twenty minutes. "How long before the event was the preparation complete?"
"Based on the deployment timeline data," he said, "the selection criteria and protocol design were finalized approximately four years before the event. The actual deployment — the protocol assignments — appears to have occurred within days of the event itself."
She absorbed this. "The four-year preparation window implies the event's occurrence was known in advance."
"Or its probability was modeled above a threshold that justified preparation," Shen said. "The Science Ministry's division was probability modeling, not prediction. They may have had a 70 or 80 percent confidence estimate rather than certainty."
"That's enough to justify the investment," she said.
"Yes," Shen said.
She wrote something in her notes. Then: "The registry. The seventeen cases. You said one is unmonitored."
Shen glanced at Chen.
"Yes," Chen said.
She looked at him. "You've seen the registry."
"Last night."
She was quiet for a moment. Processing the shape of what he hadn't told her yet and the shape of what he had. He watched her do it — the precise way she held partial information, fitting what she had against what she was missing.
"We'll talk Thursday," she said. Not a question.
"Yes," he said.

The Seoul data arrived at 2:47 PM.
He got the notification through Han Weiwei's message — she'd set up the research collaboration alert on her phone and it buzzed during the afternoon's second plenary session, which neither of them was presenting at. She showed him the notification from where she was sitting.
*Seoul National Bureau — Dr. Park Jeongmin — data transfer complete. Full profile attached. Urgent flag: secondary mechanism signature may be a classification error. Please review.*
She pulled up the data file. The primary signature read as expected: probability warp, generative type, consistent with the deployment architecture. The secondary signature was the new thing. The Seoul team had classified it as a potential calibration artifact because nothing in their taxonomy matched it.
It was not an artifact.
The secondary field ran at a lower amplitude than the primary, with a different texture — smoother at the edges, almost interface-like. The way a signal looked when it was designed to carry information between systems rather than generate its own output.
"Translation layer," he said.
"What?"
"The secondary field is designed to operate between the primary and other nodes. Carrier wave architecture." He looked at the data. "The Seoul practitioner can communicate with other network nodes at the field level. Their generative primary enables local operation. The secondary enables cross-network coordination."
Han Weiwei was very still.
"The three-type coordination model is for local networks," she said slowly. "The Concurrent Observer paper describes a minimum viable architecture. The translation type is an additional type for the global architecture." She looked at him. "This means the architect designed a two-tier structure. City-level networks coordinated by a global layer. The Seoul practitioner is a global-layer node."
"Yes," he said.
She looked at the data for a long moment. "There are more than seventeen."
"I don't know that yet," he said.
"The global architecture requires more than seventeen nodes to function," she said. "Seventeen for the global-layer coordination, plus local-network members within each city. The seventeen in my distribution data may be the global-layer only." She looked at him directly. "How many local-network nodes are there in this city?"
He held her gaze.
"I don't know the full count," he said. "I can identify three confirmed."
"Three including yourself."
"Yes."
She looked back at the data. Her research had just grown substantially in scope. He could see her filing the adjustment — not alarmed by it, but calculating what it changed about the publication plan, the methodology, the open questions that would need framing carefully.
The symposium's afternoon plenary session ran on around them, audible through the atrium doors.
She said: "The paper I'm presenting here — it's the local-network study. That's complete as presented. The global architecture is a second paper."
"Yes," he said.
"The Seoul data gets cited as an open question in the current paper's conclusion. The global-layer analysis waits." She looked at him. "Does Dr. Park in Seoul know what he has?"
"He flagged it as possibly a classification error," he said.
"I'll respond to his transfer tonight," she said. "He has a fourth type. I'll tell him what I think it is." She paused. "I won't tell him everything I think it is."
"No," he said.
She made a brief note in her file. Then she sat back and looked at the atrium ceiling. The post-session crowd was dispersing around them, and she was quiet in a way that was not discomfort — it was the specific quality she had when she had received a large amount of information and was running it against everything she already knew.
He waited.
"You knew about the Seoul data before I showed you just now," she said.
"I knew a secondary signature had been flagged," he said. "I didn't have the full profile."
"But you identified the translation layer function in about eight seconds."
"I had context to work from," he said.
She turned her head and looked at him directly. "How much context do you have that I don't?"
The question was precise. She was not asking about the specific Seoul data — she was asking about the architecture. About what he knew of the deployment's design and purpose that she had not arrived at independently.
The probability field at Level 4 ran its assessment. The honest answer was: more than she knew, less than the system knew, and the gap between those two quantities was the part that was still being filled.
"Enough to be useful to you," he said. "Not enough to give you the complete picture."
"That's an unsatisfying answer."
"Yes," he said.
She held his gaze for a long moment. Then looked back at her notes.
"Thursday," she said again.

His phone buzzed at 4:18 PM.
Lin Zhengyue.
*The committee voted this afternoon. Four to three, first ballot. The application is approved.*
He looked at the message.
Five business days since the submission. Clean committee vote — no formal review triggered. The interference Fang had placed had been reversed in time, and the application had proceeded on its own merits.
He typed: *Congratulations.*
She responded: *Come Friday evening.*
He typed: *Yes.*

The symposium's day two closed at six. The organizing committee announced the Day Three schedule: one morning plenary, a data-sharing roundtable in the afternoon, and a closing reception.
He found Han Weiwei at the sensor array in the main hall, where she was running a post-session download on the day's ambient data. Three days of real-time probability field logging in a 400-person awakened research event. The dataset was going to be unusual.
"The array ran clean today," she said, not looking up from the laptop. "The ambient distortion this afternoon hit 0.15. Below baseline."
"The anchor field is still operating from across the city," he said.
"Yes." She finished the download. "Li Xiulan. You mentioned her three months ago, and she's in the data every day. The anchor function runs continuous." She closed the laptop. "She knows what she is?"
"She's been working with it for a year and a half," he said.
Han Weiwei nodded. She pulled her bag over her shoulder and looked at him. "Shen Mingzhi has six years of research that I didn't know existed. His registry is more complete than anything I've built."
"Yes."
"You read his folder last night."
"Yes."
"You knew about the seventeenth node before you came here today."
"Yes," he said.
She looked at him. The sensor array behind her, still logging its ambient data in the now-empty hall. The probability field texture: her spatial ability at its evening register, the dimensional quality of it distinct from every other field in the building.
"You're going to look for the seventeenth node," she said.
"Yes."
"And you're not going to tell me what you find until you know what it is."
"Probably not," he said.
She made a sound that was not quite exasperated and not quite resigned. Something between them.
"Extra coffee Thursday," she said.
"You promised that two weeks ago," he said.
"I haven't forgotten," she said.
She walked out toward the atrium. He followed. The Day Two symposium closing around them — researchers collecting their materials, the corridor becoming quiet with the specific quality of an event at the end of its productive hours.
He thought about Friday evening.
He thought about Thursday.
He filed both and went to collect his things from the hotel.
One day remaining.
