The words
Every word this site uses, said plainly. Once.
The five chapters use a small set of words. Each one does a job.
Each chapter explains its words where they first do work. This page is the second place, not the first. Come here when a word stops you.
The wording of record is the Structural Glossary on the420code.org. Nothing here renames a word. It only says it plainly.
One record exists
The book: A distinction that has been made and persists. What the axiom produces every time coupling executes.
In plain words: Something happened, and it stays happened. You are reading this sentence. That is a record. Try to deny it, and the denial is another record.
In the body: A scar. A memory. A test result. Your body is a living record of everything that has happened to it.
Where it does work: everywhere. The front door. How did you get there?
Coupling
The book: The structural relation between records. What the axiom is doing at any site, continuously.
In plain words: Two things changing each other, and leaving a record of it.
In the body: A drug meets a receptor. A nurse’s hand meets a patient’s hand. Both are changed.
Where it does work: every chapter.
Window
The book: A local self-aware configuration of the interior. One self-reading loop: one person, one dog.
In plain words: One life that reads itself. You are a window. So is the patient in the next bed.
In the body: The body is the window at the scale of a life.
Where it does work: Medicine, Augmentation, The closing.
The interior, and the building
The book: The interior is one, locally instantiated at each site where the break reads itself. The building is all the windows together.
In plain words: Many windows. One awareness looking out of all of them. The awareness in me is the awareness in you.
In the body: That is why harm done to another body is not done somewhere else. It is done inside the one awareness.
Where it does work: every chapter stands on it. The full argument: the420code.org/one-awareness/
Operator
The book: A self-aware coupling-architecture with override-capacity at coupling-events where trajectory-space is wide.
In plain words: A reader who can say no. A life that reads its own state and can choose.
In the body: Your body reads itself. It notices when something is failing. It acts for itself, or it calls for help.
Where it does work: every chapter. First in Medicine.
Override
The book: The structural capacity of a self-aware coupling to commit to trajectories the raw weighting alone would not select.
In plain words: Your capacity to choose. To take a path your raw impulses would not have taken, wherever more than one path is open.
In the body: Getting up to walk when the couch pulls. Refusing the next drink. Choosing treatment, or refusing it.
Where it does work: Medicine, Addiction, The closing.
Cooperative and parasitic
The book: Cooperative if it widens or keeps the joint viable set at a cost the structure can carry. Parasitic if it shrinks it, or imposes a cost the structure cannot carry, at any operator’s resolution.
In plain words: The two verdicts. Cooperative keeps the room open or widens it. Parasitic shrinks it when nothing required it, or loads a cost onto others that they cannot carry.
In the body: Supplying the food and sleep a body needs is cooperative. Medicating the drift while withholding them is parasitic.
Where it does work: every chapter.
The corridor
The book calls it the viability corridor: the range of internal states across which the body keeps running.
In plain words: The range of states your body can keep running in. It has a width. It drifts. And it has an exit.
In the body: Body temperature has a corridor. So do blood sugar, blood pressure, sleep and the people around you. Each has walls.
Where it does work: every chapter. First in Medicine.
Budget
The book: Finite resources of energy, of repair capacity, of structural reserves.
In plain words: What a body has to spend. It decides how much drift a body can take before the corridor closes.
In the body: A rested body shrugs off a bad week. An exhausted one may not.
Where it does work: Medicine.
Drift
The book: Internal states change continuously. Drift inside the corridor is what continuous maintenance looks like.
In plain words: A body is never still. It is kept steady by constant work. Drift toward a wall is what happens when the load, the inputs or the repair have shifted.
In the body: Blood pressure creeping up over years of short sleep and long hours.
Where it does work: Medicine.
Exit
The book: What the architecture structurally does when its corridor cannot be re-widened.
In plain words: Every body leaves its corridor in the end. The exit is not a failure. It is what a body does when its corridor can no longer be widened again.
In the body: The bedside at the end of a long illness.
Where it does work: Medicine, as level five. The closing, in full.
The organism
The book: The structural unit one resolution above the individual body. Medicine is what the organism does on behalf of the bodies inside it.
In plain words: The larger structure around a body. The family. The clinic. The hospital. The food supply. The home. The people around you.
In the body: When a patient cannot get food or sleep, level one is the organism’s job, not the patient’s.
Where it does work: Medicine, and every chapter after it.
The five levels
The book calls them the correction hierarchy at biological scale, ordered by intrusiveness, by cost and by resolution.
In plain words: Five kinds of help, lowest first. One: fix the inputs and the load. Two: let the body correct itself. Three: surgery, medication, direct intervention. Four: living with permanent support. Five: care for the closing. Each level is used only where the levels below are not enough, or not fast enough.
In the body: Metabolic syndrome. Three pills for life, or first a question about sleep, food and the hours.
Where it does work: Medicine, in full. The film: Level one was never attempted.
The boundary
The book calls it the ε-boundary: the site at which an operator’s coupling spills into the joint viable set at a cost the other operators must absorb. This ε is not the ε of the axiom’s line.
In plain words: The line where what you do starts to cost others something they must carry. Below it, you are sovereign. Above it, the larger structure acts.
In the body: What you take into your own body is yours. Driving on it, or draining your dependants, crosses the line.
Where it does work: Addiction. Augmentation.
Sovereignty
The book calls it operator authority: the operator’s authority over its own coupling at the resolution where that coupling lives. Below the boundary, the operator is sovereign.
In plain words: Your authority over your own body and mind. It comes with the responsibility. Sovereignty is not absolution.
In the body: Deciding whether, and how, to take a treatment at all.
Where it does work: Addiction, Augmentation, The closing.
The noise floor
The book: The level any signal must rise above to register.
In plain words: The background a choice has to stand out against. When it rises, other paths are still there. You just cannot see them any more.
In the body: After weeks on a substance, ordinary pleasures stop registering. Company. Work. Unsedated sleep.
Where it does work: Addiction. The film: The noise floor.
The dignity-floor
The book: The minimum coupling-conditions every operator’s continued running requires.
In plain words: The minimum every body is held at, whatever else is being calculated. Pain relief. Food. Shelter. Presence. Care at the end. Nobody is pushed below it.
In the body: A patient the system cannot save still gets pain relief, food, a bed and someone in the room.
Where it does work: Medicine, Addiction, The closing.
Coupling-capacity projection
The book: what an intervention preserves downstream, read above the floor.
In plain words: When there is not enough to go around, look ahead at what the help can restore. Never the person’s standing. Never their relationships. Never how useful they are to others.
In the body: Two patients, one bed. The question is what the corridor can still become, not who the patient is.
Where it does work: Medicine.
Widening and narrowing
The book: Editing that widens the future operator’s corridor is structural maintenance. Editing that narrows it to serve someone else’s preference is parasitic contraction of an override that has not yet begun.
In plain words: An edit that takes a child from a closing to the ordinary width is repair. An edit that chooses the child in advance is narrowing. More is not wider.
In the body: Preventing a disease that kills in early childhood widens. Choosing eye colour narrows.
Where it does work: Genetic engineering. The film: The room before the occupant.
Impedance matching
The book: The operator’s modelling must be able to integrate what the augmentation delivers. The matching holds when the drift rate is at or below the control capacity.
In plain words: An addition to the body has to arrive no faster than the person can take it in. Where it does, it is permitted. Where it does not, it is refused.
In the body: A cochlear implant feeds sound at a rate the brain can learn. A link that floods the brain faster than it can follow does not upgrade the person. It breaks the loop.
Where it does work: Augmentation. The film: Bandwidth does not upgrade you.
Control capacity and drift rate
The book: Control capacity is the rate at which the modelling can integrate new coupling without fragmenting the self-reading loop. The drift rate is the rate at which the augmentation supplies coupling the architecture must integrate.
In plain words: How fast you can take things in, and how fast the device delivers them. The first must keep pace with the second.
In the body: A prosthetic leg the motor system learns. A pacemaker that runs below notice.
Where it does work: Augmentation.
The operator and the narrator
The book: The narrator is the downstream record-making that reports on the operator’s execution; it arrives after the fact. One of the operator’s capacities, not the operator.
In plain words: The person, and the person’s story about themselves. Both real. Both the person. At the end of a life they can come apart.
In the body: A frightened patient says one thing at three in the morning. The same patient, after pain relief and rest, says what they have said all their life.
Where it does work: The closing.
The six questions
The book calls them the Capacity and Coercion Protocol.
In plain words: Six questions any honest reading at the end of a life must run. They do not produce the decision. They make sure the decision is the person’s own.
In the body: Is the corridor truly closing, or was level one withheld? Is the decision stable over time? Is pain or fear speaking? Is someone pushing? Does it match the person’s whole life? Has the floor been supplied first?
Where it does work: The closing.
The Ledger
The book: The structural reading of record, substrate, corridor and propagation. Not an institution. Not an oracle.
In plain words: The honest reading of what happened and what it costs. What every chapter is doing. Institutions try to approximate it. They can get it wrong.
Where it does work: every chapter.
The ship, the wake and the ocean
The book: the image that closes every chapter.
In plain words: The ship is the person: one place where the now is being written. The wake is the pattern the ship leaves behind it. The ocean is the shared structure every wake is written into.
Where it does work: the last lines of every chapter.
The spine
The book: the five chapters on the body, Five to Nine.
In plain words: Five chapters. One account, not five. Your authority holds at every scale. So does the structure’s duty.
Where it does work: this whole site.
Kill switch
The book: A structural falsification condition attached to a chapter’s claims, published in advance. A commitment, not a hedge.
In plain words: A condition written down before any test. Meet the condition, and the claim falls. Every chapter ends with its five.
Where it does work: the end of every chapter. All of them, with their status: the420code.org/killswitches/
