144: Chapter 144 Academic Nuclear Fission

On the morning of August 6, when Jiang Lin woke up, he habitually reached for his phone on the nightstand, glanced at the time, and then pulled down the notification bar.

One unread email.

Sender: Terence Tao.

[Node 38 Wrapper]

Jiang Lin sat up and opened the email.

[Jiang Lin: I have already submitted the formalized skeleton of the double involution wrapper for Node 38 on an independent branch.

It does not change the proofs in the manuscript, but rather exposes the symmetry and conditional structures within them more explicitly. This way, when coding Node 38, there is no need to repeatedly expand that four-variable posterior measure.

Please review it at your convenience.]

Below the email was a GitHub link.

Branch name: formalization/node38-double-involution-wrapper-tao (Node 38: Double Involution Wrapper)

After reading it, Jiang Lin did not rush to click the link.

Mathematical intuition told him that this step of refactoring by Terence Tao would inevitably involve tedious variable substitutions in the probability measure space.

He first got up to wash and brush, drank a glass of warm water, and only then sat at his desk and turned on his computer.

Logging into GitHub, he entered the private repository for PFR formal verification.

Inside the repository page, a new Pull Request lay quietly.

[Pull Request No. 3: Coding the Double Involution Wrapper for Node 38]

Submitter: Terence Tao

Status: Draft

No merge requested.

Terence Tao did not push anything directly to the main branch, nor did he attempt to alter any mathematical symbols in the text of Jiang Lin's seventh-edition manuscript.

Instead, on the Lean4 formalization branch, like a master architect, he used code to build an exceptionally sturdy skeleton.

Jiang Lin clicked into the code diff tab.

The file structure was clear at a glance, with three new Lean4 source files added.

The first file defined the base types and independence assumptions of the four-variable copies.

The second file handled symmetric conditioning after fixing macroscopic observable variables, and provided the measure invariance lemma under involution mappings.

This was the deepest and most error-prone zone of the entire proof.

The third file did not write the final conclusion, but instead left a clear interface with several unproven placeholder symbols, used to seamlessly connect the finally extracted conditional mutual information terms back to the third-layer loss recovery ledger.

The amount of code was surprisingly restrained, totaling no more than three hundred lines.

There were also very few comments, but every variable naming and theorem macro was as refined as if it had been meticulously carved.

Beautiful.

Jiang Lin read through it line by line, his brain rapidly restoring these Lean4 syntax trees into underlying mathematical logic.

He immediately understood Terence Tao's processing method.

In the formalization blueprint originally conceived by Jiang Lin, Node 38 was the heaviest and most easily disorienting piece in the entire theorem prover project.

This was not because there were loopholes in the mathematical proof here, but because natural language, even the natural language of mathematicians, possessed extremely strong compressibility when conveying high-dimensional probability theory information.

In Section 4.2 of the seventh-edition manuscript, Jiang Lin poured out too many high-density concepts simultaneously in a paragraph less than half a page long.

The construction of four-variable copies, conditioning based on spectrum cluster indices, variational lower bound estimation of mutual information, convexity cutting planes for covering recursion, and finally the accounting of loss terms used to control entropy growth.

On paper, these things could be compressed by mathematicians relying on profound intuition and experience into a smooth, exquisite, and flawless argument chain.

Whenever a peer read "similarly obtained symmetric terms", their brain would automatically complete the underlying measure transformations.

But the theorem prover would not fill in the blanks for anyone.

The theorem prover was a ruthless bureaucrat; it required every object to be strictly named, every variable substitution to be explicitly declared, and every variable substitution to fall onto concrete measurable mappings, push-forward measures, and conditional kernels.

If one were to stubbornly bite through the formalization directly according to the literal meaning of the original paper, the entire code base would completely fall into deadlock due to repeatedly expanding that complex four-variable posterior measure.

The work done by Terence Tao was to encapsulate the double involution structure in Node 38—which was most likely to cause combinatorial explosion in the code—into a reusable abstract interface in advance.

This was not patching the proof, nor was it correcting any mathematical errors.

Rather, it was doing the infrastructure work of translation.

Transforming an exquisite proof that had already formed a closed loop in the human brain into formal components that could be verified by machines, maintained by the community, and continuously disassembled by later generations.

After Jiang Lin finished reading the last line of symbols in the final file, he left the first comment below the pull request.

[The proof in the manuscript remains unchanged. This wrapper accurately exposes the symmetric structure I implicitly used in the text. I will check the dependency graph to determine whether Node 39 should continue to remain independent or be treated as a corollary of this wrapper.]

Click submit.

Just three minutes later, the browser's refresh icon lit up, and Terence Tao's reply popped out, showing that the other party was also typing away on a keyboard from a remote location at this time.

[Very good. Please keep Node 39 visible for the time being, even if it might become a corollary later. Reviewers might need to see the initial location where this dependency was separated.]

Looking at these words on the screen, Jiang Lin's fingertips hovered over the keyboard for a moment.

This was a reminder that only an extremely experienced formalization mentor could give.

As a precise art, mathematical proofs often pursue minimalism and the shortest path.

But as a scientific review oriented toward the public community, its path should by no means pursue minimalism.

Some intermediate nodes, even if they could eventually be perfectly merged into a corollary in mathematical logic, should be forcibly kept independent on the topological graph at the current stage.

This was not because they were so special in algebraic structure, but because they played irreplaceable signposts along the reading path of human reviewers.

Node 39 was originally just a piece of local dependency transmission after Node 38, dealing with the fine-tuning of boundary limits.

Viewed from the perspective of pursuing code elegance, it could completely be implicitly merged into the corollary layer of Node 38.

But if it were hidden, external reviewers would experience a sense of mutation when reading the code.

They would fail to see clearly through what kind of dynamic mechanism the loss terms flowed into the next layer of covering recursion after passing through the double involution structure.

By retaining it, readers could clearly see what kind of changes in entropy deficit attribution occurred when those information loss terms overflowing from the involution structure flowed into the next layer of covering recursion.

The shortest mathematical path and the review-accessible path were indeed never the same thing.

After a mathematician of Terence Tao's caliber truly participated, the ultimate goal of this theorem prover formalization blueprint had undergone a subtle yet profound evolution.

It was no longer merely to prove to the world through self-certification that Jiang Lin's paper had no logical fallacies.

It had further become a path.

A channel helping the entire international mathematical community cross the intuition cliff and truly enter the core hinterland of this paper.

Seven in the morning.

Outside the bedroom door came the sound of his mother Zhang Xiufen knocking.

"Jiang Lin, come eat breakfast."

"Coming."

Jiang Lin acknowledged, switched the local code repository to the branch created by Terence Tao, and started the background compilation check of the theorem prover.

Then he rubbed his somewhat sore neck, opened the door, and went out.

His father Jiang Jianguo had already finished eating, and was humming a tune while hanging a bunch of brass keys on the belt buckle at his waist, preparing to go out for work.

Under Jiang Lin's insistence, that previous night shift job at the seafood market had already been resigned from.

But he could not stay idle, saying that retiring in his early forties would make people laughed at if word got out.

With no other choice, Jiang Lin arranged for him to work as a logistics warehouse management assistant at the peripheral material warehouse of the Low Entropy Workshop.

His daily work consisted of receiving and dispatching registration, seal photography, and warehouse area patrols. All inventory counting and approval for warehousing still went through the administrative process on Chen Zhi's side.

Jiang Jianguo was quite happy doing this job that was half warehouse management and half patrol inspection.

Every day, he rode his electric motorcycle out early and returned late, being punctual and on time. He was much more dedicated than Jiang Lin, who arrived late and left early every other day.

After finishing breakfast and helping to clear the bowls and chopsticks, Jiang Lin returned to his room, woke up his computer, and continued processing the code logic of the PR.

At 8:40, other members of the formal review team began coming online.

Professor Han Yanshan did not comment on how well Terence Tao's code conformed to functional specifications; as soon as he came online, he threw out a devastating question.

[After performing the conditioning of fixed macroscopic observables, there was a crucial step of transfer in the original proof—the transfer from the spectrum cluster indices to the interval indices of density thresholds.]

[In this wrapper's encapsulation, is this step of accounting transfer hidden within the underlying measure transformation?]

The question precisely hit the most subtle gap in the entire formalization.

As a top scholar in domestic combinatorial mathematics, Professor Han Yanshan's perspective on viewing code was different from mathematicians like Terence Tao who wandered between harmonic analysis, Additive Combinatorics, PDEs, and number theory for a long time.

If at the code level, the double involution structure was encapsulated too beautifully by Terence Tao, future reviewers reading this code might completely fail to notice that tiny gap when spectrum cluster indices converted to density thresholds—a gap most likely to introduce arithmetic symbol errors.

The threshold stratified set there needed to be independently proven measurable, and the boundary layer had to be handled through explicit approximation lemmas; otherwise, when conditional mutual information terms entered the loss ledger, it was very easy to leave gaps in bound scaling.

And this conversion was precisely the place in the original manuscript where bound scaling errors were most likely to occur.

Almost within five minutes after Professor Han Yanshan left a message, Ding Jian also followed up with a comment.

[I completely agree with Old Han's concerns. Terry's wrapper indeed reduced redundant code expansion, but we cannot hide the specific location where the conditional mutual information terms enter the third-layer loss recovery ledger. If implicit processing is adopted here, although the theorem prover can run through, humans will experience a serious cognitive fault when aligning the formulas on page 14 of the paper manuscript. It is recommended to retain an explicit public lemma before calling the wrapper.]

Then before long, Terence Tao's reply refreshed.

[Agreed. The wrapper should expose the conditional structure rather than hide the accounts. We can add an explicitly exposed lemma before the recovery step to clearly project the entropy deficit terms.]

Jiang Lin leaned back against his chair, looking at this series of interactive comments from different time zones and perspectives on the screen, a sense of clear transparency suddenly arising in his mind.

During those long and lonely decades in the Wasteland World, all mathematical derivations, logical constructions, and even self-refutations were completed by him alone in a dark, sunless basement.

He was both the sole author and the sole reviewer.

He had to crazily advance the proofs during the day, and at midnight tear himself apart into the most scathing opposing party to desperately search for loopholes in his own logic.

He had to write the main line while also independently cleaning up all edge degeneration case indices.

The taste of working alone for a long time—the biggest risk was never that you couldn't think of the correct route, but rather that due to the lack of external perspective collision, you would unconsciously take some logical jump you had long been accustomed to for granted as a flat ground.

And this logical jump that you had long taken for granted might be a bottomless cliff to peers walking this path for the first time.

Now, this cliff that was originally hidden under minimal expression was jointly marked out by this group of the smartest brains in the world.

Without hesitation, Jiang Lin immediately created a new file in the editor.

Named: Node 38_Explicitly Exposed Lemma.lean

Then on the first line at the beginning of the file, he typed out a detailed comment.

[This file is used to explicitly expose the account transfer from spectrum cluster indices to density threshold intervals before calling the double involution wrapper.]

This was the brand-new formalization deconstruction strategy for Node 38.

First, without borrowing the protection of any higher-order functions, directly lay bare and illuminate the account transfer from spectrum cluster indices to density threshold intervals inside the theorem prover using the most primitive algebraic inequalities.

Next, take this cleaned interface as a parameter and call the double involution wrapper written by Terence Tao.

Finally, smoothly plug the symmetric measures output by the wrapper into the third-layer loss recovery.

In this way, the code architecture maintained industrial-grade clarity, avoided volume overload, and ensured that no reviewer would miss the key account alignment due to overly clean encapsulation.

Time passed minute by minute.

The theorem prover's compiler ran frantically in the background, and green checkmarks began to light up along the edges of the source files one by one.

These green checkmarks only represented that syntax, dependency, and type checks had passed; several core placeholders still remained in the draft branch in the form of unproven warnings, and it was still short of a complete proof before truly entering the main branch.

At 10:16 in the morning.

Jiang Lin pushed his modified local commit to GitHub and completed the update below the PR.

A few minutes later, Terence Tao left a thumbs-up emoji reaction below the merge request for Jiang Lin's newly created lemma file, along with a sentence.

[Mathematics pursues elegance, engineering pursues transparency; this is the correct way of splitting.]

Immediately following was Professor Han Yanshan.

He was a traditional scholar, and simply left a concise line at the bottom.

[This way I can read it.]

Ding Jian's reply was even more concise.

[Retained]

Four brains representing the current top levels of combinatorial mathematics and formalization, crossing the distance of physical space, completed a confluence for the first time on a tiny underlying node.

Jiang Lin did not immediately mark this draft merge request as ready for review, nor was he in a hurry to advance the merge process.

Instead, he brought up the terminal, pulled the remote branch locally, and conducted a final static code check word by word against the text of Section 4.2 of the seventh-edition paper manuscript.

The natural language text of the main paper remained completely unchanged.

The formalization blueprint structure of the theorem prover was comprehensively rearranged.

The logical dependency graph was updated online.

Node 38 was split into a three-layer hierarchical structure, adding an explicitly exposed lemma.

Node 39 was retained as an independent review path signpost and not merged for the time being.

At 11:30 in the morning.

Just as Jiang Lin had finished his local static check and re-annotated the dependency graph for Node 38, his phone vibrated.

Caller ID: Liang Zhixia.

"President Jiang, there is a World Robot Conference in Beijing from August 18th to 21st."

Jiang Lin raised his eyes.

Liang Zhixia continued, "Professor Lu called me this morning. Jiangda University originally had a quota for university-enterprise achievement transformation exchange, but they couldn't produce a mature mobile platform prototype. Hengtai also has a cooperative booth in the conference's industry matchmaking area. President Xu's meaning just now was that if we are willing, they can join Jiangda University in recommending the Low Entropy Workshop to enter a small-scale technology demonstration slot."

She paused for a moment.

"It's not a main booth; time is too tight, and it's impossible for us to temporarily get an official large booth. But we can bring a G-01 C display machine into the venue to do a small-scale demonstration of an unstructured low-speed mobile platform."

"Alright. Externally, just call it an unstructured low-speed mobile platform, an early engineering prototype oriented toward industrial inspection, frontline rescue reconnaissance, and complex terrain sampling."

"For the live demonstration, let's build a small closed terrain box with gravel, slippery alternative materials, low obstacles, and non-continuous contact surfaces. Keep the slope under twenty degrees. The focus of the demonstration is not the climbing height or the obstacle-clearing distance, but how the state machine identifies foot-end anomalies, how it decelerates, how it withdraws half a step, and how it re-engages."

"Won't this be a bit insufficiently flashy?"

"Flashiness is not our goal. Showing just this one thing is enough."

"There will be two prototypes."

"The first one is the Hengtai unmanned closed-tunnel grayscale testing machine, which will stay in Jiangcheng. All appearance numbers, test logs, and hardware disassembly must be archived according to engineering standards."

"The second one is the World Robot Conference exhibition machine, heading to Beijing. The exterior can be tidied up, but the interior must be a desensitized version of the exact same core state machine. We cannot temporarily write a flashy demonstration program that looks good for the booth effect but has no engineering significance."

Liang Zhixia quickly took notes.

"Time is a bit tight."

"That's why we're having a meeting this afternoon," said Jiang Lin.

"Split the Hengtai grayscale testing and the Beijing exhibition into two separate lines. Chen Zhi will be responsible for logistics, insurance, exhibition materials, and prototype transportation. Qiu Yue will handle external email triage; do not accept any media interviews for now. Xu Man will be responsible for the hardware safety boundaries of the exhibition machine, and Chen Yan will handle log desensitization and the visualization interface for the demonstration state machine."

Liang Zhixia asked, "Are you coming to the workshop?"

"I'll arrive at two in the afternoon."

Hanging up the phone, Jiang Lin switched back to the browser, his thoughts once again immersed in the complex algebraic derivations of node 38.

At noon, just as Jiang Lin was about to go out for lunch, Ding Jian sent a message with four or five webpage screenshots attached.

[Jiang Lin, that message on the collaboration forum regarding the launch of the formalization project has begun overflowing outward on a large scale. Terence Tao's original post was very restrained and his phrasing was rigorous, but after being re-translated a few times by external information flows, the tone of domestic online public opinion has completely changed. You'd better mentally prepare yourself.]

Jiang Lin clicked on those screenshots and looked through them one by one.

The first screenshot.

That was a post from an international mathematical Physics exchange forum. The poster simply screenshotted Terence Tao's statement from the collaboration forum completely: "This is a serious manuscript, and the corresponding formalization work has also entered the active review stage," and added a line of honest explanation in bold text below.

[Note: This is not the final official announcement of the theorem, but rather an indication that a serious manuscript has officially entered the top-tier formal active review chain.]

The reposter was quite responsible and deliberately marked a simple English explanation below, which had been translated into Chinese:

[Note: This is not an official announcement of the theorem being established, but a confirmation that this manuscript has entered the top-tier active review and formalization stage.]

In the second screenshot, the information had flowed into a domestic postgraduate entrance examination/competition mathematics popular science QQ group with several thousand members.

The reposter's tone obviously carried emotional rendering.

[Big gossip! Jiang Lin's new PFR/Marton manuscript has been personally taken over by big shot Terence Tao, directly plugged into the theorem prover for formal review. Pay attention to Terry's wording; although it's not final confirmation, this means the top-tier review chain has fully started. The weight of this paper might be even more terrifying than imagined.]

The third screenshot was a flash news article from a tech news website, and the flavor had already begun to visibly deviate from academic rigor itself.

The flavor began to skew.

[Terence Tao personally joins the review chain! Genius scholar Jiang Lin drops another heavyweight bomb, with his new paper manuscript suspected of frontally challenging the core conjecture of Additive Combinatorics, completely shocking the international mathematics community.]

The fourth one had completely degenerated into a traffic carnival by certain self-media outlets trying to capture attention. The accompanying image was even a blurry side-profile photo of Jiang Lin back at Jiangda University, and the headline was extremely sensational.

"After Jiangs Brick, Jiang Lin is eyeing PFR again? Terence Tao willingly plays the foil, as a top formalization team endorses him overnight!"

After reading the last screenshot, Jiang Lin's facial expression showed no fluctuation whatsoever; he simply calmly placed his phone back on the desk.

This was the physical law of the public information world: transmission equals distortion.

In a highly specialized academic circle, an objective judgment repeatedly supplemented with restrictive conditions, adverbial clauses, and disclaimers by rigorous mathematicians—once it left its original context soil and flowed into the vast ocean of mass media—would immediately have all its trimmings representing caution and indecision ruthlessly sheared away by the public opinion engine.

In the end, only a few keywords most likely to trigger the public's dopamine secretion would remain in the information flow.

Terence Tao.

Jiang Lin.

PFR/Marton conjecture.

Top-tier review.

Suspected major breakthrough.

As for what the truth was?

Ordinary netizens didn't understand what small doubling sets were.

Didn't understand double involution at the Shannon entropy level.

And understood even less what kind of technological barrier the eleventh-power polynomial covering bound of K meant in the proof.

Nor did they need to understand.

They only needed to see one name—Terence Tao.

In this era, for the general public, the name Terence Tao itself was a huge cultural yardstick transcending mathematical symbols.

When ordinary people saw that even this winner of the fields medal, widely recognized as one of the smartest brains of the contemporary era, personally stepped down to spend time sorting manuscripts and writing code to enter the review chain, everyone would immediately and instinctively realize that this matter was definitely not some mediocre affair that could be defined by crank delusions or ordinary padding papers.

The secondary dissemination after the overflow of professional news was like an uncontrolled nuclear fission, wantonly deforming in every corner of the internet.

Jiang Lin was actually not dizzy from this sudden spotlight.

After replying to Ding Jian, he thought for a moment and sent another instruction to Liang Zhixia.

[Hang up the external response caliber for the workshop in advance, and establish a physical isolation zone.]

Liang Zhixia replied almost in seconds.

[The public opinion monitoring software has already sounded an alarm. The template is ready and can be launched at any time.]

Soon, the automatic reply templates for the external contact email and official social media accounts of the Low Entropy Workshop were fully updated.

The first paragraph, targeting academic inquiries.

[Notice regarding inquiries about Mr. Jiang Lin's recent mathematical work: This academic work belongs to Mr. Jiang Lin's personal academic affairs and is currently still in the stage of peer review and machine formal verification. Before the relevant academic community reaches a final conclusion, the Low Entropy Workshop does not accept any media interviews related to it, nor does it respond to or endorse any conclusive or predictive statements not supported by published papers.]

The second paragraph was the hardcore bottom line that forcibly dragged the topic back to reality.

[All externally released calibers of the Low Entropy Workshop at the current stage are limited to the relevant public test information and business-technical docking of the G-01 series unstructured terrain mobile platforms. Thank you for your attention.]

At two in the afternoon, Jiang Lin arrived at the Low Entropy Workshop.

He did not go up to the second-floor meeting room right away, but first went to the hardware assembly workshop on the first floor of the plant.

On the lift platform in the center of the workshop, a G-01 C with a mottled shell and mud-and-sand scratch marks was in a semi-disassembled state.

The protective layers of the six limb foot-ends had been removed, and the deep groove on the outside of the right-front foot—ripped apart jointly by rusty nails and gravel—looked particularly jarring under the lights.

Several groups of sensor wire harnesses were separated by temporarily numbered zip ties. A white label was pasted next to the reducer output end, on which was written the disassembly inspection time, joint number, and initial radial runout re-test value.

Chen Yan and Xu Man were squatting next to the equipment, one holding an electronic vernier caliper and the other making annotations on the waveform chart on a tablet.

Seeing Jiang Lin walk in, Xu Man straightened up and handed over a freshly reorganized material screening matrix.

"General Manager Jiang, according to the engineering target performance package you provided earlier, I have re-screened the realistic supplier options for the foot-end protective layer and the outer wear-resistant material."

Jiang Lin took the table, his gaze sweeping across rows of material grades and parameters.

"Tell me the conclusion."

"Carbon fiber modified POM is retained as the mainstay direction for high-impact operating conditions. Domestic ordinary POM is downgraded and only allowed to enter test scenarios with better flatness and lower impact strength. Glass fiber reinforced POM is eliminated due to too high of a brittle fracture risk. Ultra-high molecular weight polyethylene only retains the low-pressure wear-resistant group and will not enter mine gravel slope and closed tunnel tests."

Xu Man tapped several red-highlighted data points with a pen.

"Glass fiber POM has sufficient rigidity, but under irregular local impacts, the edge micro-crack propagation is too fast. Ultra-high molecular weight polyethylene's wear resistance is indeed good, but its compressive creep is insufficient. Once the foot-end battles sharp rocks for a long time, the sensor strain baseline will drift."

Jiang Lin finished reading the anti-shear strength curve and nodded.

"Go in this direction. Don't dirty the input source of the state machine just to save material costs."

At this time, Chen Yan projected an enlarged waveform curve onto the large screen in the workshop.

"And this, that group of contact force deviations you marked in the blind test data earlier—I re-disassembled it. Now looking at it, it's mixed with at least three types of things: real terrain impedance perturbation, protective layer lateral shear deformation, and adhesive layer hysteresis."

On the screen, the three curves clung tightly together within a short window of twenty to fifty microseconds, separating only at extremely subtle positions.

"The problem is that the second and third types are too similar," Chen Yan said, frowning. "If we separate them directly in the whole-machine data, the state machine can easily mistake the protective layer anomaly for adhesive layer hysteresis, or vice versa."

"Don't let the whole-machine tunnel test wash the variables for us."

Jiang Lin looked at those almost overlapping curves and mused.

"Add a separate foot-end component-level bench, control the inputs, and only release two variables: protective layer material and adhesive layer thickness. Use an independent press, high-speed camera, and external force sensor as controls. Measure the difference between the second and third types first, and then let the state machine ingest the data."

Chen Yan immediately noted it down in his notebook.

Jiang Lin put the material matrix back on the desk.

"Let's go, upstairs for the meeting."

A few minutes later, in the second-floor meeting room of the plant, the whiteboard had been re-divided into two halves by Liang Zhixia.

The left side was —— [Hengtai Unmanned Closed Tunnel Grayscale Test].

The right side was —— [2022 Beijing World Robot Conference Technical Demonstration].

Separated in the middle by a red line.

Below the red line was a line of printed text that Liang Zhixia had just pasted up.

[Closed testing and public demonstration, data isolation, caliber isolation, prototype isolation.]

Qiu Yue was processing emails.

She took off her headphones and said, "General Manager Jiang, there are even more interview invitations. Financial media, tech media, and self-media all have them. There are also several emails asking if they can interview us in advance about the World Robot Conference."

"Template reply," Liang Zhixia said without raising her head.

Qiu Yue nodded: "It's already up. For anything involving General Manager Jiang's mathematical work, uniformly reply that it is still in the peer review stage and interviews are not accepted. For anything involving Low Entropy Workshop products, uniformly reply that a limited public technical demonstration will be conducted during the World Robot Conference, with specific information subject to subsequent official materials."

Chen Zhi sat next to the filing cabinet with a logistics manifest spread out in front of her.

"General Manager Jiang, the time in Beijing is too tight. Ordinary logistics is unstable; I suggest the exhibition machine goes via dedicated transport, and personnel arrive one day early. Exhibition insurance, temporary admission passes, equipment manifests, lithium battery transportation instructions, and on-site electricity applications all need to start preparation today."

"Use dedicated transport," Jiang Lin said. "The exhibition machine cannot be checked into an unattended warehouse. The entire transportation process must be photographed and numbered, and the seal numbers must go into the archives."

"I'll make the transportation archives," Chen Zhi nodded.

Xu Man pushed a new hardware plan to the center of the desk.

"On my end, I'm splitting the prototype into two lines."

"The Hengtai grayscale testing machine uses unit 2 of the G-01 C, focusing on reinforcing the foot-end protective layer and the reducer output end impact margin."

"The Beijing exhibition machine uses unit 3 of the G-01 C, tidied up in appearance, adding transparent observation windows, but without any decorative parts that affect structural strength."

Speaking to this point, her voice became more serious.

"The exhibition machine cannot lower safety redundancy for the sake of looks. There are many people in the exhibition hall, and any out-of-control incident is more troublesome than in a testing ground."

"Correct."

Jiang Lin nodded.

"The safety state machine threshold for the exhibition machine is more conservative than the engineering machine. Better to move slowly than to allow any sudden acceleration."

Chen Yan turned on his computer and projected a simplified state machine diagram onto the wall.

"I'm preparing to make a visualization interface for the World Robot Conference exhibition machine."

"It's not a control backend, just displaying status."

"The audience can see the logs corresponding to actions such as the current foot-end contact state, risk level, deceleration trigger, half-step withdrawal, and re-engagement. But all parameters are desensitized, displaying only the state name and timeline."

Jiang Lin looked at the screen.

That interface was very rudimentary, with only a horizontal timeline, a few state boxes, and timestamps left from each state switch.

"That's fine," Jiang Lin said. "But remove the words 'intelligent decision-making'."

Chen Yan was stunned: "Then what should it be called?"

"State machine response."

Chen Yan smiled slightly: "This term isn't very marketing-friendly."

"We aren't going there to sell toys."

The Hengtai line subsequently entered the refinement stage.

Xu Man was responsible for the hardware reinforcement of the grayscale testing machine.

Chen Yan was responsible for the closed-tunnel log synchronization.

Chen Zhi was responsible for test site admission documents, equipment manifests, and insurance.

Liang Zhixia was responsible for confirming the test schedule with Professor Xu Mingchuan.

Xu Man asked, "When does the grayscale test start?"

Liang Zhixia said, "Hengtai gave two windows: August 10th to 12th, or August 13th to 15th."

Jiang Lin glanced at the calendar: "Enter the site on the 10th."

"So fast?"

"The faster, the better," Jiang Lin said. "We have to go to Beijing on the 18th. The Hengtai grayscale test must complete its first round before the World Robot Conference, otherwise everyone at the booth will chase us with questions: 'Have you guys actually run your so-called complex terrain capability in a real closed environment?'"

Liang Zhixia understood.

The Beijing World Robot Conference was not merely a promotion node, but also an industry public interrogation ground.

They could choose not to exaggerate and not to make gimmicks, but they couldn't go empty-handed.

The G-01 C passing Hengtai's thirty-seven-degree gravel slope blind test was the first card.

The first round of data from the unmanned closed-tunnel grayscale test was the second card.

And the World Robot Conference was where the Low Entropy Workshop placed these two cards on the industry table for the first time.

The meeting lasted until four in the afternoon and was pretty much concluded.

Chen Yan finally couldn't hold back the curiosity in his heart, turned his head, and whispered to Jiang Lin: "General Manager Jiang, although I know I shouldn't ask, it's all over the place outside now, saying whether you've proven another major conjecture that can be written into the history of mathematics?"

As soon as these words came out, except for Jiang Lin, everyone else's ears in the meeting room involuntarily pricked up.

The external caliber was the external caliber, but privately, everyone still wanted to hear the big boss's inner thoughts.

Although the boss's words and actions were steady on ordinary days, and his style could even be called rigorous, he was only eighteen after all.

What if he felt proud of himself and had a bout of youthful arrogance just this once?

"It's not that it has been proven, it's that the review chain for the proof manuscript has officially started," Jiang Lin looked at Chen Yan, correcting this erroneous qualitative vocabulary.

As soon as the words fell, Xu Man gave a thumbs up, and the anticipation on Chen Yan's face visibly collapsed.

Qiu Yue lowered her head and pretended to look at emails, but the corners of her mouth couldn't help twitching.

Liang Zhixia expressionlessly added a line to the meeting minutes.

[Regarding mathematics-related issues, similarly no conclusive statements are made internally.]
