Glossary

Terms used on this site. Every paper also defines the terms it uses, so no paper depends on this page.

commit gate
A check that runs before an irreversible action. A proposal may not authorize itself. The gate commits or refuses and writes a receipt.
receipt
A record written for every decision: the prediction and its timestamp before the act, the outcome, the match, the joules by label, and the refusal reason if any.
completeness predicate C(z)
A written test that maps the state z of a task to 0 or 1, for example tests pass, a proof checks, or an output matches a reference. A task is complete when C(z) = 1.
energy to correct completion (J*)
The least expected energy, in joules (J), that a system needs to reach C(z) = 1 with failure probability at most δ. Systems that pass are ordered by J*; ordering by a real number is a total preorder.
value of information (VoI)
The expected gain in a decision's payoff from observing a quantity before deciding, minus the cost of observing it (Howard, 1966).
impedance tax
The extra work a machine consumer does because information arrives in a format made for people to read: encode, parse, tokenize and, for a model, read the extra tokens. Defined with units in "AI" Reads Human; no joule value is claimed for it yet.
token
The unit a language model reads, a piece of text produced by a tokenizer. The same records give different token counts in different formats and under different tokenizers.
Landauer bound
The minimum heat dissipated by erasing one bit at temperature T: k_B T ln 2, about 2.87 × 10⁻²¹ J at 300 K (Landauer, 1961).
cheapest-first cascade
An order of mechanisms (gears) tried from lowest to highest expected energy, stopping at the first that passes the check. Expected energy is minimized by trying gears in decreasing order of p_i / c_i, with p_i the pass probability and c_i the expected energy (Simon and Kadane, 1975).
Mixture of Limits
The rule of using the cheapest gear that passes the check and stopping when further spend cannot change C(z). The cheapest-first cascade is one instance.
σ-law selector
A selector that picks the next act by the ratio of pass probability to energy cost and stops when the next act's expected gain is below its energy cost.
plateau
The least spend that closes a task. Past it, further tokens, parameters or joules cannot change C(z).
replay class
A label on an answer stating how it was produced. An answer labeled ModelGenerated cannot be relabeled Deterministic.
software reference implementation
The software used to test a claim without board-level metering. Its energy figures are estimates.
est_j
An analytical energy estimate: operation counts times stated energy constants, in joules.
reported_j
An energy figure read from an operating-system or on-chip counter, such as RAPL package energy minus a stated idle baseline.
measured_j
A joule reading from an external wall or shunt meter on a named rail, with its calibration stated. Never summed with reported_j, est_j or trajectory_j.
trajectory_j
Work computed from measured physical trajectories and a calibrated potential, for physical act cycles near the k_B T scale.
evidence classes
Modeled: a stated formula. Simulated: a program or hardware-description run. Measured: a named meter on a stated device and workload.
board_metered
A page flag that is true only when a labeled meter returned a board energy reading for that paper.
Form and fit
A program written as a state machine P = (S, E, δ, D, λ): states, events, a pure step function, an append-only log whose fold is the state, and outputs. The form is that shape (Gurevich's Abstract State Machine theorem); the fit is a program's vocabulary, rules and initial state.
Reality Code Engine (RCE)
A programming system, studied in its own paper, in which a program is written once as a Form and code in other languages is generated from it.
Metabolic Intelligence
A class of computer intelligence designed to run inside a fixed energy budget B, studied in its own white paper.
WCA (Wise Computer Automation)
The Rust software implementation of the commit gate studied in Metered Commit Gates, Part I.
proposed Universal Law of Agency
A proposed definition of an agent with an energy budget and a refusal rule, stated in the agency paper. It is a proposal.
