The words

record — A difference that was made and held. A footprint. A memory. This sentence.

reading — Taking in a record from where you stand. Always from a place, always now.

perspective — The place you read from: where you are, and the whole history you carry.

priority — Coming first; standing above the others; having the last word.

principle of relativity — The rule that no perspective has priority: every reading is from somewhere, and none is the record as it is.

kill switch — A condition, stated in advance, under which a claim dies.

possibility — What could still be true, given what you can see from where you stand.

rule out — To show, from your view, that an answer cannot be true.

click — One tick: the smallest step. The same tick measures distance and time.

simultaneous — At the same time. In the 420 Code, always a reading, never a fact of the record.

now — The one moment everyone reads and writes from. Shared by all. Read by none.

count — A site’s own clock: the count of what has happened to it.

test — A way of settling a claim that does not depend on any one viewer, and that can say no.

prediction — A claim about what you will find, made before you look.

invariant — What every reader reads the same, wherever they stand and however they move.

interval — The distance between two events, in space and time taken together. Every reader reads it the same.

sigma — How far a result sits from a measurement, counted in the measurement’s own margin of error.

corpse — A prediction that died on its stated condition. Shown with its date, never repaired, never deleted.

fired — Said of a kill switch whose stated condition was met: the claim died.

crossing record — The count of ticks light takes to cross from one place to another. In AP52, this is what distance is.

dot — One record of one action, on the surface of what has happened. Accumulated dots make patterns, and patterns make predictions.

pattern — What many dots make when they are read together.

ego — The part of you that needs to be right. One of the four filters on how a person reads the dots.

mood — How you feel at the time you read. One of the four filters.

bias — A lean you bring before you look. One of the four filters.

intention — What you meant to do. The story you tell yourself about why the dot appeared. It does one job: it predicts whether the same dot appears again.

consequence — What an action caused. What is measured.

bolt-on — A story fitted afterwards to an outcome that fits anything.

convergent — Coming together on one answer as more records are gathered.

prophecy — A claim that names tomorrow without saying why. A claim with no condition. Nothing in it says what would prove it wrong, so nothing can. It risks nothing and explains nothing.

condition — The if a claim stands on. Name it, and you have named where the claim could fail. “The condition is the kill switch.”

inevitability — The claim that something must happen, whatever anyone does. A claim about tomorrow with no condition.

induction — You count what happened before, and you expect more of the same. Useful. It risks something and explains nothing.

regularity — Something that has always gone the same way: fire burning, the sun rising.

necessity — What must follow, not only what has followed so far. Induction carries none.

deduction — A step that must follow from what came before. It does not count what happened. It looks at what makes it happen.

conditions — The four things that must be true for a record to exist: Symmetry, Break, Record, Constraint. Not chosen; forced by the existence of the record.

axioms — Notebook I’s name for the four conditions, S, B, R, C, stated as the work’s ground rules. Written together in one line they are the axiom, 1:1 + 1×ε @ AS.

floor — The one statement under every way of being sure: one record exists. It cannot be denied, because the denial writes it.

performed — The grade of the floor. Not assumed and not proved: done by anyone who tries to get out of it. “Performed is not a weaker word than proved. It is a harder one.”

tested claim — A claim built on the floor that names the condition that would kill it, and then faces measurement.

error bar — The width around a measured number: how finely the instrument can see. A prediction inside the bar agrees with the measurement as far as the instrument can tell.

Architecture B — The way of knowing that publishes its weaknesses and calls them kill switches. (The Interior, Ch. 3.) Full treatment at step 10.

consciousness — Sits downstream of awareness, with observation between them. On this step it is the thing the two prophecies make claims about: that it ends with the body, or that it goes on.

authority — A source that tells you what is right. In Architecture A, one that can only be believed.

Architecture A — Rules from an idea placed above you that can be read more than one way and cannot be checked; questioning it is the crime.

interpret — To read what a text or idea means. A finite text read by different people in different times gives different readings.

report — What someone else tells you. A record of a record.

window — One person. One place the world is seen from.

debt — Something the work has not yet derived, written down in public as owed.

verdict — The answer a society gives about who is right and what happens next. In A it comes from the strongest group; in B from measured consequences.

coalition — A group that sides together: tribe, ideology, identity, who is on our side.

restitution — Repair first: what was broken or taken is restored. The first level of correction.

falsifiable — Able to be shown wrong. A falsifiable claim says in advance what would kill it. (The Interior, Ch. 3: “Every claim is falsifiable.”; G, 2 November 2026.) Met at How we work.

verified — Tested, and passed. By logic: it cannot be denied. Or by experiment: it landed where it said it would. (Step 8, the two kinds of sure; G, 2 November 2026.) Met at How we work.
