Chapter Summaries

As Class D’s answer window closed, Gu Heng preserved page versions, timestamps, and withdrawal records without treating uncertain clues as proof. An anonymous message shifted his next investigation toward the page rewrites, while the final settlement record began generating without revealing the submitter, answer, or class.

• Gu Heng corrected the report about Class B, distinguishing its system notification from Class D’s note, and told Hirata to record facts without assuming the sources matched.
• Gu Heng kept two withdrawing members’ names out of the Cold Backup permissions, while Hirata recorded that preserving their withdrawals did not mean they agreed with Gu Heng.
• Karuizawa chose to retain her masked record despite the exposure, and Gu Heng logged her decision.
• Kushida gave Gu Heng timestamps showing that later rewrites cut out Class D’s responsibility statement, but withheld her source and kept the original screenshot.
• Gu Heng recorded that he alone bore the wording risk for Class D’s lack of a unified submission recommendation, then received an anonymous message urging him to investigate who made them believe someone had submitted.
• The answer window closed and the final settlement record began generating, but the public page still showed no submitter, answer, or class affiliation.

Gu Heng and Class D separated the official settlement, their closed response portal, and the still-changing public annotation layer while preserving each page version. After the final record appeared without identity or point-source details, a new annotation challenged Gu Heng’s investigation, leaving him to determine who could still write to the public page.

• Gu Heng, Yukimura, and Horikita compared page versions and confirmed that official settlement records, Class D responses, and public annotations were separate layers with different permissions.
• Kushida gave Gu Heng a timestamp for an external screenshot but asked him to keep her name off Class D’s shared record, so he left its source unknown.
• Hayakawa stopped forwarding notices, Karuizawa preserved an original page without transferring it to Class D, and Ayanokoji warned Gu Heng not to equate unopened results with having none.
• After the final settlement record appeared, Gu Heng had Yukimura save the page versions before anyone opened their results.
• A new public annotation appeared after settlement, and Gu Heng recorded it while identifying the annotation layer’s remaining write access as the next question to investigate.

Class D learned that its identity-exam settlement had cost it fifty points, but the individual results remained private and no one could identify the submitter. As Class B suspended its verification and the public annotation layer remained editable, Horikita kept Class D’s response channel closed, leaving the class to determine who could still edit the external layer.

• Hirata recorded Class D’s fifty-point deduction while Gu Heng and Yukimura separated the official class result from members’ private results.
• Horikita added a boundary stating that Class D accepted the deduction but would not disclose personal results, and Yukimura set different access permissions for class and individual information.
• Class B, through Ichinose, suspended delivery of the previous page timestamp; Horikita kept Class D’s response channel closed and recorded the resulting loss of verification.
• Kushida gave Gu Heng a screenshot showing that the public annotation “Confirmed before settlement” was added after the settlement record was generated, but he refused to treat it as testimony for any personal result or identify her as its source.
• Hayakawa, Karuizawa, and Ayanokoji each kept their own records or results private, while Gu Heng logged the gaps in the information trail without linking them to a single person.
• When the public annotation layer remained active despite Class D’s closed response channel, Horikita chose not to reopen it, and Gu Heng recorded the unresolved question of who could still edit the external layer.

Gu Heng and Class D confirmed that their accounts could not edit the public annotation layer, while its contents continued to change independently of the official settlement. Horikita kept Class D’s response portal closed and accepted responsibility for the reputational cost, leaving Gu Heng to investigate which pages shared the layer and which identities could write to it.

• Yukimura tested the annotation layer with a Class D account and confirmed that it could not write, while the official settlement remained unchanged.
• Horikita kept Class D’s response portal closed despite the risk that outsiders would misinterpret the annotations.
• Kushida reported the time of a change to the annotation layer but withheld the original image, and Hayakawa confirmed that no new anonymous alerts had reached him.
• Karuizawa provided a timestamp showing that another page also had an annotation layer, though it had no Class D marker.
• A new annotation falsely claimed that Class D knew who had edited the page, and Horikita added her name to the decision to keep responses closed.
• Gu Heng recorded separate questions about which pages shared the annotation layer and which identities could successfully write to it.

Gu Heng investigated how pages linked to the public source PUB-1, distinguishing entries and reference versions from page holders and manual writers. The chapter ended with Class D still lacking a name, but with a test planned to identify which entry an application changed.

• Gu Heng mapped the different page layers and found that Class D's D-03 page referenced PUB-1 entry 17-2 while P-02 retained version 17-1; Horikita stopped Hirata from forcing an unauthorized refresh.
• Kushida showed Gu Heng a processed application record for PUB-1 entry 17-1 → 17-2 but withheld the page ID, and Class D agreed to keep page IDs and timeline positions in a cold backup.
• Ichinose reported that Class B's page referenced PUB-1 but had no Class D note, while providing no full location; Gu Heng recorded only the confirmed fields.
• Hayakawa clarified that he had not received an anonymous reminder, and Gu Heng removed his unsupported claim that no propagation chain existed.
• Karuizawa asked Gu Heng not to connect her provided time with P-02, so he moved the time to individual retention and lost a cross-page comparison point.
• Gu Heng logged that D-03 remained at version 17-2 while P-02 still referenced 17-1, then planned a test in which a page holder would submit an addition request for a specified entry.

Gu Heng tested whether a public annotation application could alter a page, confirming that A-03 was processed and the visible version changed while the identities behind the change remained unknown. The test cost Class D several verification routes, and Class B made further cooperation conditional on a public distinction between class facts, personal choices, and public entries.

• Gu Heng guided the girl through submitting A-03, which recorded her application without changing the public entry or revealing her identity.
• A-03 was processed, and the public entry changed from version 17-1 to 17-2 with a new sentence, but the manual writer and trigger identities remained hidden.
• Kushida showed Gu Heng a cropped record of A-02 and admitted that Class B knew testing was underway, though she had not shared the page or applicant.
• The girl stopped further applications, and Karuizawa withdrew her external comparison authorization after the new sentence cast applicants as suspects.
• Ayanokoji said another page remained at version 17-1 but refused to identify it, leaving Gu Heng unable to verify the page or establish synchronized updates.
• Class B required Class D to publicly distinguish class facts, personal choices, and public entries before sharing another time discrepancy, while Class D's official settlement still showed -50.

Class D saved a bounded, independently archived response, but the public source still misrepresented it and added a new entry. Gu Heng gained limited version evidence from Class B and Kushida while Karuizawa and Ayanokoji withdrew pages from comparison, leaving Class D to choose whether to protect its remaining records or investigate the misinterpretation before the next refresh.

• Horikita saved Class D response R-02, separating the official class fact, individual choices, and unconfirmed submitter from public annotations.
• Nine seconds later, PUB-1 changed D-03 from 17-2 to 17-3 and claimed Class D refused to explain who pressed confirm; Gu Heng recorded the timing as correlation, not causation.
• Ichinose accepted that Class B could verify R-02 was not an exam answer, and Class B returned a field showing its page still cited 17-2 twelve seconds after the save.
• Kushida gave Gu Heng an extracted field showing another unidentified page displayed 17-3 nine seconds after R-02, while withholding the original image and Karuizawa's withdrawn page numbers.
• Karuizawa kept her old record but withdrew permission for public cross-verification, and Ayanokoji crossed his page number out of Gu Heng's comparison table while offering a limited version-boundary observation.
• Class D gained one point of verification but faced a choice before the next refresh: protect its remaining pages or investigate the mistaken interpretation.

Gu Heng and Class D investigated conflicting version records while respecting the undisclosed page holder’s refusal and Karuizawa’s limits on using her old records. After the public source refreshed, an outside message to Karuizawa shifted the investigation toward whoever was using her refusal to pressure someone else.

• Gu Heng compared D-03, Class B’s page, and an undisclosed page, finding that their versions and reference statuses differed rather than refreshing simultaneously.
• Ichinose supplied Class B’s version record, while Gu Heng rejected attempts to identify the withdrawn page holder or treat the withdrawal as proof of hidden evidence.
• Yukimura’s read-only request for the undisclosed 17-3 page was denied, and Gu Heng recorded the refusal without retrying.
• Karuizawa asked Gu Heng to retain her historical records but prohibit their use in public verification, and he updated the comparison labels.
• Ayanokoji clarified that P-02 was not Karuizawa’s page, so Gu Heng removed a mistaken connection from the investigation.
• After the public source refreshed without revealing the third page’s location, Karuizawa received a message about a sentence someone else had saved for her, and Gu Heng decided to investigate who was using her refusal to make another person speak first.

Karuizawa defended her right to keep her private page from public verification, while Gu Heng and Ayanokoji tried to keep her boundaries from becoming evidence. After an external annotation recast her words as an admission, Gu Heng shifted the investigation toward whoever was using her answer to alter Class B’s cooperation terms.

• Kushida confronted Karuizawa with an unsourced note and pressed her to say whether she had seen an altered public statement, while Ayanokoji stopped the question from exceeding the page’s boundaries.
• Karuizawa clarified that she had withdrawn public cross-verification authorization, not denied Class D’s settlement, and refused to submit her private page for others to interpret.
• Karuizawa asked Gu Heng to record her boundary anonymously and decided to deliver her next statement face-to-face only to Ichinose; Gu Heng also deleted a record that framed her as publicly denying the matter.
• Class B accepted the anonymous boundary field, but an external annotation on its public page claimed Karuizawa had already said she did not deny it, prompting Hirata to warn that the boundary was being twisted into an admission.
• Gu Heng decided to investigate who was using Karuizawa’s answer to change Class B’s cooperation terms, while Karuizawa saved a new unanswered question asking who would speak for her if she stayed silent.

Gu Heng investigated how misleading public pages affected students’ choices, while Class D and Class B set boundaries on what they would share. He chose to meet the unnamed Class B member who had withdrawn a time window, shifting the inquiry from page versions to the moment her decision changed.

• Gu Heng confirmed that D-03's new note misrepresented Karuizawa, while Horikita kept R-02 intact and restricted who could save a new version.
• Ichinose shared an anonymous Class B behavioral field showing that a member withdrew a time window before PUB-1's 17-3 appeared, and Kushida gave Sudo a copy of R-02-F-1.
• Ichinose barred Class B from accepting secondhand fields from Kushida, and Ayanokoji advised Gu Heng to let the unnamed member choose whether to meet him.
• Karuizawa saved a boundary statement, and two seconds later P-02 changed versions; Gu Heng refused to assume the events were connected.
• Class B offered an oral account from the unnamed member, and Gu Heng chose to meet her rather than pursue who handled the public entry.

Gu Heng recorded an anonymous Class B member’s account of how Kushida’s card led her to withdraw from an exchange, while restricting access to protect her identity and choices. The account connected the card to a change in behavior but did not identify who handled it, leaving Gu Heng to consider what Kushida was willing to pay for the result.

• Ichinose brought an anonymous Class B member to provide one recorded oral account, and Gu Heng limited the record to three behavioral events.
• The Class B member said she received R-02-F-1, withdrew her time window before PUB-1’s D-03 showed 17-3, and felt the card meant her time would be used to support Class D’s claim.
• Gu Heng recorded the member’s loss of trust without attributing her choice to Kushida’s plan, and restricted the account’s access and copying.
• The member added that someone had asked whether Class D would treat her as hiding the answer if she withheld her time, but refused to identify the source.
• The member left without giving her name, and Gu Heng kept her oral account separate from the card record and the public page version.
• Ayanokoji told Gu Heng he had never had proof of a handler, while Gu Heng concluded that the next issue was what Kushida would pay for the result.

Gu Heng and Ichinose set stricter rules for exchanges after Class B stopped accepting Kushida’s secondhand information, while Karuizawa directly withdrew permission for public cross-verification. As the identity exam’s archival deadline approached, Gu Heng shifted to waiting for people to give accounts themselves, leaving the next question of who would still allow others to explain their choices.

• Ichinose told Gu Heng that Class B would no longer accept Kushida’s secondhand fields and recorded Karuizawa’s boundary after Karuizawa withdrew permission for public cross-verification without denying the records or Class D’s settlement.
• Gu Heng saw Ayanokoji outside the reception area and recorded Karuizawa’s direct communication without adding its contents to Class D’s shared page.
• Kushida confirmed that R-02-F-1 had changed willingness to exchange evidence, while Sudo refused to let her use his result or involve him in testing others.
• Ichinose set rules requiring both parties to use their own accounts, limiting exchanges to numbers and times, and allowing refusal of future exchanges after delivery; Horikita told Gu Heng not to turn anonymous statements into class orders.
• Gu Heng changed his strategy to waiting for people to come forward, recorded that Kushida’s delivery had caused behavioral impact, and saved Ichinose’s notes sealing ORAL-B-01’s main segment and requiring separate consent for supplementary meetings.

After the Identity Exam settlement, Gu Heng and Class D preserved privacy boundaries while accepting a 50-point deduction, and Ichinose shared limited information about pressure on Class B members. As the cruise ship investigation was archived, Class D began preparing for the Sports Festival by deciding how to assign proposals and responsibilities.

• The class terminal announced Class D’s 50-point deduction, and Horikita restored the archive’s read-only and personal-result protections.
• Gu Heng met privately with Ichinose and a Class B member, who said she had not confirmed an additional submission and described pressure to share her private time.
• Ichinose kept Class B’s original records private, while Gu Heng recorded only unconfirmed behavioral judgments.
• Kushida passed along a condition restoring exchanges for qualifying accounts, but Gu Heng told her she remained excluded from participating directly.
• Ayanokoji gave Gu Heng a preview of the Sports Festival schedule, prompting Horikita, Sudo, and Hirata to plan voluntary event proposals and shared responsibility.
• Gu Heng left the class draft untouched and archived the Identity Exam records, with the Sports Festival date as the next task.

After an archival notice confirmed that a submission attempt had been recorded without revealing who made it or what answer they gave, Gu Heng limited Class D’s cooperation with Class B to a verified behavior field. As the group prepared for sports festival registrations after returning to school, they protected personal boundaries and left an unidentified exchange offer unresolved.

• Gu Heng explained that the archival supplement showed only that someone had confirmed a submission before the answer window closed, while Sudo accepted that it did not reveal the submitter or answer.
• Ichinose shared Class B’s account of an unnamed person refusing to disclose personal terminal contents, and Gu Heng recorded the refusal only as a restricted behavior field with limits on its use.
• Gu Heng and Yukimura separated the post-archive refusal from earlier behavior evidence and marked an exchange message without a recipient as unestablished.
• Horikita changed the registration form’s label from “not registered” to “Choice not yet submitted,” while Kushida offered to help collect sports festival registrations without deciding for anyone.
• Gu Heng rejected an unidentified offer to exchange public registration order and instructed Horikita to collect forms simultaneously without announcing their order.

Horikita organized Class D’s Sports Festival sign-ups so students could volunteer without personal results or registration order pressuring them. After exchanging totals with Ichinose and finding an anonymous note about withdrawing from public events after seeing a personal terminal, Gu Heng left his own registration blank and the class faced a decision about accepting the withdrawal.

• Horikita set up voluntary event, training-time, and substitute sheets, while Sudo signed up for physical events and set limits on how he could be assigned.
• Gu Heng urged simultaneous collection to conceal registration order, and Horikita adopted the process while allowing students to leave spaces blank.
• Class D collected three physical-event registrations, two logistical-support registrations, and four substitute availabilities without recording who submitted first.
• Ichinose offered to exchange registration totals, and Gu Heng agreed to share totals but not names or order.
• Gu Heng found an anonymous note saying its writer would temporarily avoid public events after seeing a personal terminal, and Horikita filed it separately from the registration statistics.
• Hirata posted the registration totals with Gu Heng’s space blank, leaving Class D to decide whether to accept the anonymous withdrawal.

After an anonymous student withdrew from a public event, Horikita and Gu Heng kept her private reason out of class records while arranging to fill the vacant role. Sudo became temporary coordinator, and the chapter ended with the class waiting for the school’s full rules and the student’s privacy boundary still intact.

• Kushida reported that an unnamed student had withdrawn from a physical event, but Gu Heng refused to let the class use her private reason to rank alternates.
• Horikita asked the alternates to volunteer; when one accepted the event but needed training, Sudo took the coordinator role and insisted the alternate confirm the choice personally.
• Kushida asked whether the withdrawing student could return, and Horikita said she could register again but could not bypass those who had already taken responsibility.
• Gu Heng and Horikita separated public duty information from private explanations, while Hirata went to speak with the alternate.
• Gu Heng received Ichinose's conditional receipt and later her confirmation that someone had withdrawn over personal terminal boundaries, with no names or private details shared.

Gu Heng and Class D verified that both classes had exchanged registration totals, but no private details or identities. Horikita set limits on preparations and responsibility, leaving anonymous withdrawals and unfilled registration spaces unresolved before the first meeting.

• Gu Heng received confirmation from Ichinose that Class D and Class B had exchanged totals of five and seven registrations, with only accounts and timestamps retained.
• Horikita and Gu Heng kept the totals out of the event sheet, while Hirata organized five confirmed registrations and two substitute forms.
• Sudo volunteered to coordinate confirmed events, and the class recorded that he was responsible only for confirmed portions.
• Kushida asked whether the withdrawn student could reconfirm anonymously, but Horikita said the student would need to return based on the current blank fields.
• Ayanokoji turned off Class B's projected totals, and Gu Heng filed anonymous activity records separately as Class D prepared for the next day's meeting.

Class D began preparing for the Sports Festival by setting boundaries for registrations, responsibilities, and substitutions while the school’s rules remained unreleased. Gu Heng helped shape a changeable form, which was set to move into a public competition after the school announced more details.

• The Identity Exam page became read-only, and Sudo announced that he would not fill unconfirmed fields or sign anyone up without their consent.
• Hirata collected voluntary event categories, training times, and substitute preferences, while Karuizawa volunteered for logistics and offered to substitute only with advance confirmation.
• Horikita, Sudo, and Hirata took responsibility for event confirmation, training coordination, and external communication, and Gu Heng added a personal-confirmation step for changes.
• Ayanokoji warned that the form needed room for changes, and Chabashira confirmed that the school had not yet released the official Sports Festival arrangements.
• Sudo and Hirata went to seek confirmed substitutes and registrations, while Karuizawa said she would confirm her own availability before asking others.
• Class D stored its incomplete preparation form, and Gu Heng anticipated bringing it into a public setting once the next round of preparations began.

Gu Heng and Horikita organized Class D’s Sports Festival preparation around confirmed volunteers and clear responsibilities while keeping unconfirmed registrations private. After Ryuuen challenged their approach, Class D recorded its first training schedule and left the remaining choices open until the rules were announced.

• Gu Heng and Horikita reviewed the notice and kept Sudo’s role limited to Class D’s preparation liaison.
• Sudo, Hirata, Horikita, and Gu Heng organized training for confirmed volunteers without recruiting people just to complete the forms.
• Ichinose told Class D that Class B was also preparing from confirmed registrations and refused to treat class totals as consent.
• Gu Heng stopped Sudo from responding to Ishizaki’s provocation and redirected him to record training times.
• Ryuuen challenged Class D’s preparation and Sudo’s authority, but Gu Heng and Horikita maintained their boundaries.
• Karuizawa volunteered as a substitute, and Class D recorded its first endurance and logistics preparation windows while keeping other registrations private.

Gu Heng and Class D tested stamina and logistics by recording repeatability, recovery, and confirmed availability rather than ranking students by a single result. They finished the first round without selecting a champion or eliminating anyone, and posted only preparation times while keeping individual results private.

• Gu Heng had Hirata divide stamina tests into start, sustain, and recovery sections, and Class D recorded whether participants could repeat their performance.
• The first applicant faltered after a fast start, while the second applicant paced herself steadily and qualified for a retest.
• Sudo completed the second section but had to wait to recover before attempting the third, and he recorded a future start time without claiming a logistics slot.
• Ryuuen and Ishizaki mocked Class D's approach, but Ryuuen acknowledged that the class was choosing students who could keep going next time.
• Karuizawa confirmed a logistics time slot and adjusted it to create a handover, while Horikita and Gu Heng kept stamina and logistics records on separate sheets.
• Class D filed three kinds of results and posted only the first-round preparation times, keeping individual test results private.
