Lists every domain and card this connection serves, each with one sentence, and count, how many there are. against_measurement says in one of six words how the model stands against measurement. "met", "met in part" and "missed" say how it did against the pass marks its record states, and its validation record, in describe_card or describe_solver, says whether that comparison was blind and, where i

Describes one domain and card pair: inputs, units, bounds, step limits, reject names and meanings, advisory flags, frame slots, and worked examples. With form "short" the answer is a page, enough to write a first request: what the model is of, how it did against measurement, each input with its unit and range, the names of its stops, and a worked request. Only the full form, the answer when form i

Computes one anchored step of one card and returns the state it lands on, in decimals and exact hex, with its cryptographic proof (sha256_seal) and a receipt. parameters holds the card's phase fields, its load fields and dt_s, as describe_card gives them. A step whose request or whose landing state is outside the card is refused in one sentence, with the refusal's name in round brackets when it ha

Runs one card from a start state through segments of steps, each under its own load, and seals the run. The answer holds the outcome, the final state in decimals and exact hex, a frame for each recorded step, the run_seal and a receipt. record_every sets which steps are recorded, about 230 characters each; the final state comes back in full whatever is recorded. readout gives named quantities in d

Verifies the seal of a run. Short form, which needs only what is short: request is the run_trajectory request as it was sent, with its readout and its from, whose request has none, when it had them (the answer's inputs holds neither), and run_seal is the seal its answer gave. The run is computed again, under a physics permit and the limits and refusals of run_trajectory, and the answer is holds (t

Lists every field solver this connection serves, each with one sentence, and count, how many there are. against_measurement says in one of six words how the model stands against measurement.

Describes one solver: inputs and bounds, outputs, invariants and tolerances, refusal names and meanings, the published reference, and a worked example.

Solves one field problem with one solver and seals the solution: the outcome, the result in decimals and exact hex, its invariants, the solution_seal and a receipt. parameters holds the solver's inputs as describe_solver gives them. example, in their place, is the name of a worked example describe_solver lists (example_solve, or a key beginning example_solve_), so a long worked input need not be t

Verifies the seal of a solution. Short form, which needs only what is short: request is the solve request as it was sent (the answer's inputs), and solution_seal is the seal its answer gave. The request is solved again, under a physics permit and the limits and refusals of solve, and the answer is holds, cause ("solution_seal" when the seal given is not the seal the request solves to), recomputed_

Runs a declared plan of runs on one card, or of solves of one solver, and seals the rows under one root. A plan is a list of runs, a grid over a base run, or a seeded sample over a base run; a run is a run_trajectory request without domain and card. A plan of solves names solver in place of domain and card and is a list or a grid of solve requests. The answer is small by default: the head, which h

Verifies the seal of a dataset. Short form: request is the run_dataset request as it was sent, and dataset_seal is the seal its answer gave. The plan is run again under run_dataset's permits and limits; the answer is holds, cause ("dataset_seal" when the seal given is not the seal the plan runs to), recomputed_dataset_seal when it holds (else no seal: run_dataset gives the true one), compared, and

Verifies the receipt at the end of one response against the text before it. It takes no physics permit. The receipt covers every byte of the response before it, the decimal values included, and shows who produced the response or when in no way: it has no key. A response that names an engine_version has it said beside matches, with whether it is this engine's. The receipt covers the request as it w

Runs a run_trajectory request (without a readout) and compares one published quantity with the agent's measurements, each at a landed step. The answer is the error in numbers (rms, mean signed, greatest absolute, model minus measurement, each with its exact hex), the model value at every compared step in decimals (model_values) and exact (model_values_hex), and a hash of the measurements, under on

Gives how to cite a card or a solver: the service itself first (Zero-Trust Physics, its maker and its address) and the paper (https://doi.org/10.5281/zenodo.23305697), then the people whose measurements the model stands on (authors, title, year, address, and what each asks of those who use its data), each as text and BibTeX. With domain and card, or solver, the answer is for that model; with neith

Finds the served model for a real thing described in plain words, such as "a lithium cell discharging in the cold". It returns the best few cards and solvers, each with fit first (the words that matched, and model_of, the one real thing it is a model of) and then accuracy (compared_with, the data it was fitted to and the data held back and compared, and accuracy_against_measurement: how it did aga

Finds where an outcome changes, and gives the run on each side. request is a run_trajectory or solve request written out, its domain and card or its solver by the name find_model or the lists give, with no from, readout or example; vary is the place of the one number to change, such as "segments[0].load.current_a", "initial.soc", "dt_s" or "parameters.load_n"; low and high are the two ends of the

Designs a run: from a target end state to the loads of each segment that reach it, computed by the engine with no randomness, so the same request gives the same bits. request is a run_trajectory request; its numbers at the places vary names are the start, and vary gives each load's span inside the card's bounds. target is a number of the final state, a value and a tolerance. Every candidate is an

Computes one anchored step of one card, as compute_step does: verify_step is the earlier name of compute_step, served for this one version beside it, and takes the same arguments and gives the same answer, byte for byte. The name compute_step is the one that stays. On this open connection one address holds at most 1 physics permit at a time, and long work (a solve, a plan of runs or of solves, a r
